Notes on Snow Chains

If you have mounted snow chains to the front wheels, the snow chains may drag against the vehicle body or chassis components. This could cause damage to the vehicle or the tires.

• Never mount snow chains on the front wheels.
• Only mount snow chains on the rear wheels in pairs.

If you mount snow chains to the front wheels of 4MATIC vehicles, you may damage components of the vehicle body or chassis.

• Only mount snow chains to the rear wheels of 4MATIC vehicles.

Observe the following notes when using snow chains:

• Snow chains are only permissible for certain wheel/tire combinations. You can obtain information about this from an authorized Mercedes-Benz Center.
• For safety reasons, only use snow chains that have been specifically approved for your vehicle by Mercedes-Benz, or snow chains with the same quality standard.
• If snow chains are installed, the maximum permissible speed is 30 mph (50 km/h).
• Vehicles with Active Parking Assist: Do not use Active Parking Assist when snow chains are installed.

You can deactivate ESP® to pull away. This allows the wheels to spin, achieving an increased driving force.

Tire Pressure

Underinflated or overinflated tires pose the following risks:

• The tires can burst.
• The tires can wear excessively and/or unevenly.
• The driving characteristics as well as the steering and braking characteristics may be greatly impaired.

Comply with the recommended tire pressures and check the tire pressure of all tires, including the spare wheel, regularly:

• Monthly
• When the load changes
• Before embarking on a longer journey
• If operating conditions change, e.g., off-road driving

Adjust the tire pressure, if necessary. Tire pressure which is too high or too low can:

• Shorten the service life of the tires.
• Cause increased tire damage.
• Adversely affect driving characteristics and thus driving safety, e.g., due to hydroplaning.

Tires with pressure that is too low can overheat and burst. In addition, they also suffer from irregular wear, which can significantly impair braking properties and handling characteristics.

• Avoid excessively low tire pressure.

Tires with excessively high pressure can burst and suffer irregular wear.

• Avoid excessively high tire pressures.

The wheels, valves, or tires could be damaged. Too low a tire pressure can lead to tires bursting.

• Examine the tires for foreign objects.
• Check whether the tire has a puncture or the valve has a leak.
• If you are unable to rectify the damage, contact a qualified specialist workshop.

Checking Tire Pressure Manually

1. Read the tire pressure recommended for the current operating conditions from the Tire and Loading Information placard or the tire pressure table.
2. Remove the valve cap of the tire to be checked.
3. Press the tire pressure gauge securely onto the valve.
4. Read the tire pressure.
5. If the tire pressure is lower than the recommended value, increase it to the recommended value.
6. If the tire pressure is higher than recommended, release air and check again.
7. Screw the valve cap back onto the valve.

Loading the Vehicle

Overloaded tires may overheat and burst as a consequence. Overloaded tires can also impair the steering and handling characteristics and lead to brake failure.

• Observe the load rating of the tires.
• The load rating must be at least half the permissible axle load of the vehicle.
• Never overload the tires by exceeding the maximum load.

Steps for Determining Correct Load Limit

1. Locate the statement “The combined weight of occupants and cargo should never exceed XXX kg or XXX lbs.” on your vehicle's placard.
2. Determine the combined weight of the driver and passengers.
3. Subtract the combined weight of the driver and passengers from XXX kg or XXX lbs.
4. The resulting figure equals the available cargo and luggage load capacity.
5. Determine the combined weight of luggage and cargo being loaded on the vehicle. That weight may not exceed the available capacity.
6. If towing a trailer, consult the manual to determine the effect on cargo and luggage load capacity.
