Possible solution 왘 Observe the coolant temperature gauge in the

instrument cluster (컄 page 26). If the temperature rises again: 왘 Contact an authorized Mercedes-Benz

Light Truck Center immediately.

During severe operating conditions and stop-and-go city traffic, the coolant tem- perature may rise close to 248°F (120°C).

! The engine should not be operated with the coolant temperature above 248°F (120°C). Doing so may cause serious engine damage which is not covered by the Mercedes-Benz Limited Warranty.

Warning!

Driving when your engine is overheated can cause some fluids which may have leaked into the engine compartment to catch fire. You could be seriously burned.

Steam from an overheated engine can cause serious burns and can occur just by opening the hood. Stay away from the engine if you see or hear steam coming from it.

Turn off the engine, get out of the vehicle and do not stand near the vehicle until the engine has cooled down.

Make sure the jack is positioned correctly under the axle housing. Always lower the vehicle onto sufficient capacity jackstands before working under the vehicle.

If the vehicle is not raised as described, it could slip off the jack as a result of vibra- tions (e.g. opening or closing a door or the tailgate).

Observe the safety guidelines in the “Flat tire” section (컄 page 390) when using the vehicle jack.

Warning!

The jack is designed exclusively for jacking up the vehicle under the axle housing. To help avoid personal injury, use the jack only to lift the vehicle during a wheel change. Never get beneath the vehicle while it is supported by the jack. Keep hands and feet away from the area under the lifted vehicle. Always firmly set parking brake and block wheels before raising vehicle with jack.

Do not disengage parking brake while the vehicle is raised. Be certain that the jack is always vertical (plumb line) when in use, especially on hills. Always try to use the jack on level surface.

Since the safety characteristics are limited in the event of an accident, brush guards are not intended to prevent injury or damage in the event of an accident. Also check state and local regulations on installation and use.

Raise and lower brush guard in an open space with plenty of room.

Practical hints Replacing wiper blades

Warning!

Wiper blades

! Never open the hood when the wiper arm is folded forward. Hold on to the wiper when folding the wiper arm back. If released, the force of the impact from the tensioning spring could crack the windshield. Do not allow the wiper arms to contact the wind- shield glass without a wiper blade inserted. For your convenience, you should have this work carried out at an authorized Mercedes-Benz Light Truck Center. 왘 Remove the SmartKey from the starter

switch.

For safety reasons, switch off wipers and remove SmartKey from starter switch before replacing a wiper blade. Otherwise, the wiper motor could suddenly turn on and cause injury.
