In the tire pressure table
To check the tire pressure using the tire pres-
sure specifications in the tire pressure table,
proceed as follows:
1.
Determine the nominal tire pressure for the
vehicle’s tires by referring to the informa-
tion on the driver’s door pillar.
2.
Check the tire pressure in all four tires, e.g.,
using a pressure gage.
3.
Correct the tire pressure if the current tire
pressure deviates from the target tire pres-
sure.
4.
Make sure that all valve caps are screwed
onto the tire valves.
The tire pressure specifications in the tire pres-
sure table correspond only to cold tires or to
tires at the same temperature as the ambient
temperature.
If vehicle
is equipped with an emergency
wheel: Check the tire pressure of the emer-
gency wheel in the cargo area regularly and
correct as necessary.
On the control display
To check the tire pressure using the tire pres-
sure information on the control display, pro-
ceed as follows:
1.
Go through the menu as follows: Apps
menu / "Vehicle" / "Vehicle status" / "Tire
Pressure Monitor".
2.
Check whether the current tire inflation
pressure levels deviate from the intended
tire pressure value.
3.
Correct the tire pressure if the current tire
pressure deviates from the target tire pres-
sure.
The display of current tire pressure on the con-
trol display may be restricted when the vehicle
is stationary. The tire pressure will update after
a short drive.
After correcting the tire pressure
If your vehicle is equipped with a Tire Pressure
Monitor, the corrected tire pressures are ap-
plied automatically. Make sure that the tire set-
tings are correct. When using tires not found in
the tire inflation pressure specifications on the
control display, reset the Tire Pressure Moni-
tor.
If your vehicle is
equipped with the flat tire
monitor, reinitialize it.

Uniform Tire Quality Grading
Quality grades can be found where applicable
on the tire sidewall between tread shoulder
and maximum section
width.
For example: Treadwear 200; Traction AA;
Temperature A
DOT Quality Grades
Treadwear
Traction AA A
B C
Temperature A B C
All passenger car tires must conform to Fed-
eral Safety Requirements in addition to these
grades.
Treadwear
The treadwear grade is a comparative rat-
ing based on the wear rate of the tire when
tested under controlled conditions on a speci-
fied government test course. For example, a
tire graded 150 would wear one and one-half,
1 g, times as well on the government course
as a tire graded 100. The relative performance
of tires depends upon the actual conditions
of their use, however, and may depart signifi-
cantly from the norm due to variations in driv-
ing habits, service practices and differences in
road characteristics and climate.
Traction
The traction grades, from highest to lowest,
are AA, A, B, and
C.
Those grades represent the tire's ability to
stop on wet pavement as measured under
controlled conditions on specified government
test surfaces of asphalt and concrete. A tire
marked C may have poor traction perform-
ance.
The traction
grade assigned to this tire is
based on straight-ahead braking traction tests,
and does not include acceleration, cornering,
hydroplaning, or peak traction characteristics.
Temperature
The temperature grades are A, the highest, B,
and C, representing the tire's resistance to the
generation of heat and its ability to dissipate
heat when tested under controlled conditions
on a specified indoor laboratory test wheel.
Sustained high temperature can cause the
material of the tire to degenerate and reduce
tire life, and excessive temperature can lead to
sudden tire failure. The grade C corresponds
to a level of performance which all passenger
car tires must meet under the Federal Motor
Vehicle Safety Standard No. 109. Grades Band
A represent higher levels of performance on
the laboratory test wheel than the minimum
required by law.
WARNING
The temperature grade for this tire is estab-
lished for a tire that is properly inflated and
not overloaded. Excessive speed, underinfla-
tion, or excessive loading, either separately
or in combination, can cause heat buildup
and possible tire failure. There is a risk of
accident, injury and a risk of damage to prop-
erty.

Safety information
WARNING
Damaged tires can lose tire pressure, which
can lead to loss of vehicle control. There is
a risk of accident, injury, and property dam-
age. If tire damage is suspected while driving,
immediately reduce speed and stop. Have
wheels and tires checked. Drive carefully to
an authorized service center or another quali-
fied service center or repair shop. Have the
vehicle towed or transported as needed. Do
not repair damaged tires, but have them re-
placed.
WARNING
The wheels, tires and chassis components
can become damaged when driving over
curbs, road damage, or other obstacles.
Larger wheels have a smaller tire cross-sec-
tion. The smaller the tire cross-section, the
higher the risk of tire damage. There is a risk
of accident, injury, and property damage. If
possible, avoid driving over curbs, road dam-
age or other obstacles, or drive over them
slowly and carefully.
Exchanging wheels and
tires
Mounting and wheel balancing
Have the wheel mounted and balanced by an
authorized service center or another qualified
service center or repair shop.
Suitable wheels and tires
General information
Only certain wheel/tire combinations are suita-
ble, depending on vehicle and equipment. The
vehicle manufacturer determines wheel/tire
combinations based on the following criteria:
▷
Tire size, e.g., tire width, aspect ratio.
▷
Wheel size, e.g., rim diameter, offset.
For more information on wheel/tire combina-
tions and special equipment, contact an au-
thorized service center or another qualified
service center or repair shop.
Safety information
WARNING
Wheels and tires that are not suitable for
the vehicle can damage parts of the vehicle.
There is a risk of accident, injury, and prop-
erty damage. The vehicle manufacturer rec-
ommends that you use only wheels and tires
that have been recommended for the vehicle
type.
Warning
Wheel/tire combinations that are not suitable
for the vehicle can affect vehicle handling
and a number of system functions, e.g.,the
Antilock Braking System or Dynamic Stability
Control. There is a risk of accident, injury,
and property damage. The manufacturer of
the vehicle recommends that you use wheels
and tires that have been recommended by
the vehicle manufacturer for the vehicle type.
Following tire damage, have the original
wheel/tire combination remounted on the ve-
hicle as soon as possible.

Changing run-flat tires
When changing from run-flat tires to standard
tires, it must be ensured that the vehicle con-
tains an emergency wheel or tire mobility kit.
For more information, contact an authorized
service center or another qualified service cen-
ter or repair shop.
Wheel change between axles
Different tread wear patterns can occur on the
front and rear axles depending on individual
driving conditions. The tires can be rotated in
pairs between the axles to achieve even abra-
sion. For more information, contact an author-
ized service center or another qualified service
center or repair shop. After changing a wheel,
check the tire pressure and correct as neces-
sary.
Storing tires
When storing tires, do not exceed the maxi-
mum tire pressure specified on the tire side-
wall.
When storing
tires, note the following:
▷
Store wheels and tires in a cool, dry and
dark place.
▷
Protect tires from coming into contact with
oil, grease, and solvents.
▷
Do not leave the tires in plastic bags.
▷
Remove dirt from wheels or tires.
Runflat tires
Principle
Runflat tires permit continued driving under
limited conditions even in the event of a com-
plete tire pressure loss.
General information
The wheels consist of tires that are self-sup-
porting to a limited degree and may also in-
clude special rims.
The reinforced tire sidewall makes it possible
to continue driving to a limited extent if a tire
loses pressure.
Follow
the instructions for continuing to drive
with a flat tire.
Safety information
WARNING
The vehicle handles differently when a runflat
tire has insufficient or no tire pressure; for
instance, reduced directional stability when
braking, braking distances are longer and the
self-steering properties will change. There is
a risk of accident, injury, and property dam-
age. Drive moderately and do not exceed a
speed of 50 mph/80 km/h.
WARNING
Heavy trailers can start swinging when con-
tinuing to drive with a flat tire. There is a
risk of accident, injury, and property damage.
Do not exceed a speed of 35 mph/60 km/h
when driving with a trailer and a flat tire. If the
trailer swings, brake immediately and apply
necessary steering corrections as carefully as
possible.
WARNING
Vibrations or loud noises while driving can
indicate the final failure of a tire. Tire compo-
nents may come loose. There is a risk of ac-
cident, injury, and property damage. Reduce
your speed and stop. Do not continue driving.
Contact an authorized service center or an-
other qualified service center or repair shop.

Tire Pressure Monitor
Principle
The Tire Pressure Monitor monitors the tire
pressure and issues a warning if the tire pres-
sure has dropped.
The
sensors in the tire valves measure the tire
pressure and tire
temperature.
Depending on the tires detected or registered,
the system displays the specified nominal
pressures on the control display and compares
them with the current tire pressures.
General information
When using tires not found in the tire inflation
pressure specifications on the vehicle, such as
tires with special approval, the Tire Pressure
Monitor must be actively reset. The system will
then take over the current tire pressures as the
target pressures.
When
operating the system, also note the in-
formation found in the Tire inflation pressure
chapter.
Additional
information:
Tire inflation pressure, refer to page
Safety information
WARNING
The display of the target pressures is not
a substitute for the tire inflation pressure de-
tails on the vehicle. Incorrect entries in the
tire settings can lead to incorrect target tire
inflation pressure values. In this case, it can-
not be guaranteed that the notification of a
tire pressure loss will be reliable. There is a
risk of injury and risk of property damage.
Make sure that the sizes of your mounted
tires are displayed correctly and match the
information on the tires and the tire inflation
pressure specifications on the vehicle.
Functional requirements
To use the Tire Pressure Monitor, the following
functional requirements must be met:
▷
After each tire or wheel change, the system
detects and updates the mounted tires on
the control display and displays them after
a short trip.
▷

vate until after driving for a few minutes:
▷
After a tire or wheel change.
▷
After a reset, when using tires with spe-
cial approval.
▷
After changing tire settings.
▷
In the case of tires with special approval, a
reset was performed after a tire or wheel
change or after adjusting the tire pressure.
▷
Wheels with tire pressure sensors are
mounted.

Vehicle handling with damaged tires
Vehicles driven with a damaged tire will han-
dle differently, potentially leading to conditions
such as the following:
▷
Greater likelihood of skidding of the vehicle.
▷
Longer braking distances.
▷
Changed self-steering properties.
Modify your driving style. Avoid abrupt steering
or driving over obstacles, for instance curbs or

System limits
Temperature
The tire pressure depends on the tire's tem-
perature.
Driving or
exposure to the sun will increase the
tire temperature, thus increasing the tire infla-
tion pressure.
The tire
inflation pressure is reduced when the
tire temperature falls
again.
These circumstances may cause a warning
when temperatures fall very
sharply.
Following a temperature-related warning, the
target pressures are displayed on the control
display again after a short distance.
Sudden tire pressure loss
The system is not able to indicate sudden and
serious tire damage and the resulting loss of
tire pressure caused by external circumstan-
ces.
Failure performing a reset
For tires with special approval, this system will
not function correctly if it has not been reset.
For example, a flat tire is being reported de-
spite the tires having the correct pressure.

Tire repair set
Principle
The tire repair set is used to temporarily seal
minor tire damage so that it is possible to con-
tinue driving.
The
filled in tire sealant closes the damage
from the inside when it
hardens.
The compressor can be used to check the tire
inflation pressure.

Safety information
DANGER
If the exhaust pipe is blocked or ventilation is
insufficient, harmful exhaust gases can pene-
trate the vehicle. The exhaust gases contain
pollutants which are colorless and odorless.
In enclosed areas, exhaust gases can also
accumulate outside of the vehicle. There is a
danger to life. Keep the exhaust pipe free and
ensure sufficient ventilation.
NOTICE
The compressor can overheat during ex-
tended operation. There is a risk of property
damage. Do not run the compressor for more
than 10 minutes.
Filling the tire with sealing compound

System limits
If the tires cannot be made ready to drive, con-
tact an authorized service center or another
qualified service center or
repair shop.
If your vehicle is equipped with a Tire Pressure
Monitor, note the following: using tire sealant
can damage the tire pressure sensor. If the tire
pressure sensor is damaged, have it replaced
at the next opportunity.
Emergency wheel
Principle
In the event of a flat tire, one emergency spare
wheel maximum can be used as a replace-
ment for defective tires. The emergency wheel
is only intended for temporary use until the
faulty tire/wheel has been replaced.
General information
Also check the tire pressure of the spare wheel
in the cargo area regularly, and correct as nec-
essary.
If the vehicle
is equipped with a Sport brake,
the emergency wheel can only be mounted on
the rear axle. If there is tire damage on the
front axle, the emergency wheel must first be
fitted on the rear axle on the same side of the
vehicle. The intact wheel of the rear axle can
then be mounted on the front axle.
Safety information
WARNING
The emergency wheel has particular dimen-
sions. When driving with an emergency
wheel, changed handling characteristics may
occur, for instance reduced directional stabil-
ity when braking, longer braking distance,
and changed roll steer in the stability limit.
There is a risk of accident, injury, and prop-
erty damage. Drive moderately and do not
exceed a speed of 50 mph/80 km/h.
WARNING
The vehicle can be damaged when the emer-
gency wheel is used for too long. There is a
risk of accident, injury, and property damage.
Drive moderately and do not exceed a driving
distance of 600 miles/1,000 km.

The jack is optimized for lifting the vehicle
and for the jacking points on the vehicle only.
There is a risk of injury. Do not lift any other
vehicle or cargo using the jack.
WARNING
When the jack is not inserted into the jacking
point provided for this purpose, the vehicle
may be damaged or the jack may slip when
it is being cranked up. There is a risk of injury
and risk of property damage. When cranking
up the jack, ensure that it is inserted in the
jacking point next to the wheel well.
WARNING
A vehicle that is raised on a jack may fall
off of the jack if lateral forces are exerted
on it. There is a risk of injury and risk of
property damage. While the vehicle is raised,
do not exert lateral effort on the vehicle or
pull abruptly on the vehicle. Have a stuck
wheel removed by an authorized service cen-
ter or another qualified service center or re-
pair shop.
NOTICE
Using an impact wrench to loosen or tighten
the wheel lock bolt can damage the wheel
lock bolt. There is a risk of property damage.
Only use a lug wrench to loosen and tighten
the lug bolt lock.
Securing the vehicle against rolling
away
General information
The vehicle manufacturer recommends secur-
ing the vehicle to prevent it from rolling away
when changing a wheel, in addition to engag-
ing the parking brake.
On a level surface
Place chocks or other suitable objects in front
and behind the wheel that is diagonal to the
wheel being changed.
On a slight downhill gradient
Place wheel chocks or other suitable objects,
e.g., rocks, under the wheels of the front axle
and rear axle, opposite the rolling direction.
Lug bolt lock
Principle
The wheel bolt lock offers effective protection
against wheel theft.
