PRINCIPLE OF OPERATION
Using the Terrain Management
System
The terrain management system optimizes
drivability and comfort by maximizing
traction when operating on different types
of terrain.

Press the TM button on the center console
to choose between the following modes:
Note:
Changing terrain modes could
automatically change your 4X4 setting for
optimal performance.
E283048
Normal
- For on-road
conditions. Select this mode
before driving on surfaces which
are similar to a hard road surface or once
the need for a special mode has passed.
Note:
This is the default when you switch
on your vehicle and whenever you select 4x2
via the four-wheel drive control.
E283044
Grass/Gravel/Snow
- For
off-road conditions. Select this
mode where loose or slippery
material such as packed snow, ice, grass,
or a thin layer of gravel or sand covers a
firm surface. If your vehicle cannot gain
traction in deep snow, switching off the
traction control system could help.
Note:
Make sure you switch traction control
back on when you regain traction.
E225313
Mud/Ruts
- For off-road
conditions. Select this mode for
muddy, rutted, soft or uneven
terrain.
E283037
Sand
- For off-road conditions.
Select this mode in soft dry sand
or deep gravel. If crossing wet
sand that could be sufficiently deep
enough for the wheels to sink into the
surface, select Mud/Ruts mode.
Note:
The Grass/Gravel/Snow, Sand and
Mud/Ruts modes are for off-road use only.
Note:
The curve control portion of the
AdvanceTrac® system is unavailable when
you select Sand or Mud/Ruts. If the system
becomes inoperable, selecting some modes
may not be possible and a message
displays. If it becomes inoperable due to a
system fault, all of the mode indicators on
the control turn off and one of the following
messages appears in the information
display:
TERRAIN MANAGEMENT SYSTEM
FAULT
Switching the engine on and off may clear
the fault. If that does not work, have the
system serviced by an authorized dealer.
MODE CHANGE NOT ACCEPTED,
RETRY
This mode change cannot be made at the
time of your request. Try the mode change
again.
Off-road Screen
You can continuously monitor the
real-time status of your vehicle's off-road
systems using the information display.

(If Equipped)
Note:
Operating your vehicle in any of the
off-road modes does not guarantee that it
cannot become stuck in sand, snow or mud
or other debris. It is your responsibility to
assess off-road situations and determine if
the terrain is passable.
