Possible cause/consequence Possible solution You are driving with the parking brake set.

왘 Release the parking brake (컄 page 57).

EBV, ABS, ESP inoperative See Operator’s Manual

The EBP, the ABS, and the ESP® have switched off due to a mal- function. The BAS is also switched off. The brake system is still func- tional but without the EBP, the ABS, and the ESP® available.

왘 Continue driving with added caution. Wheels may lock during hard braking, reducing steering capability.

왘 Have the system checked at an

authorized Mercedes-Benz Light Truck Center as soon as possible.

Failure to follow these instructions increases the risk of an accident.

Display message Check brake fluid level

Possible cause/consequence Possible solution There is insufficient brake fluid in the reservoir.

왘 Risk of accident! Carefully stop the vehi- cle in a safe location or as soon as it is safe to do so.

왘 Apply the parking brake (컄 page 66). 왘 Contact an authorized Mercedes-Benz

Light Truck Center. Do not add brake flu- id! This will not solve the problem.

! If you find that the brake fluid in the brake fluid reservoir has fallen to the minimum mark or below, have the brake system checked for brake pad thickness and leaks.

Warning!

Driving with the message Check brake fluid level displayed can result in an ac- cident. Have your brake system checked im- mediately. Do not add brake fluid before checking the brake system. Overfilling the brake fluid reservoir can result in spilling brake fluid on hot engine parts and the brake fluid catching fire. You could be seriously burned.

Display message Coolant level Stop car, switch engine off

Possible cause/consequence Possible solution The coolant is too hot. Among other possible causes (the cooling fan could be malfunctioning), the poly-V-belt could be broken.

왘 Stop the vehicle in a safe location or

as soon as it is safe to do so.

왘 Turn off the engine. 왘 Apply the parking brake (컄 page 66). 왘 Check the poly-V-belt.

If it is broken: 왘 Do not continue to drive. Otherwise

the engine will overheat due to an inoperative water pump which may result in damage to the engine. Contact an authorized Mercedes-Benz Light Truck Center.

If it is intact: 왘 Wait for the message to disappear

Display message

Possible cause/consequence Possible solution

왘 Observe the coolant temperature in the

multifunction display (컄 page 166). If the temperature rises again: 왘 Contact an authorized

Mercedes-Benz Light Truck Center immediately.

During severe operation 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 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 engine 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.

Possible cause/consequence Possible solution The coolant level is too low.

왘 Add coolant (컄 page 370). 왘 If you have to add coolant frequently,

have the cooling system checked by an authorized Mercedes-Benz Light Truck Center.

Warning!

Do not spill antifreeze on hot engine parts. Antifreeze contains ethylene glycol which may burn if it comes into contact with hot engine parts. You could be seriously burned.

! Do not ignore the low engine coolant level warning. Extended driving with the message and symbol displayed may cause serious engine damage not covered by the Mercedes-Benz Limited Warranty. Do not drive without sufficient amount of coolant in the cooling system. The engine will overheat, causing major engine damage.

Warning!

The vehicle jack is located underneath the storage compartment floor.

The jack is designed exclusively for jacking up the vehicle at the jack take-up brackets built into both sides of the vehicle. 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.

Make sure the jack arm is fully seated in the jack take-up bracket. Always lower the vehicle onto sufficient capacity jackstands before working under the vehicle.

왔 Replacing SmartKey batteries If the batteries in the SmartKey or the SmartKey with KEYLESS-GO* are discharged, the vehicle can no longer be locked or unlocked. It is recommended to have the batteries replaced at an autho- rized Mercedes-Benz Light Truck Center.

Warning!

Keep the batteries out of reach of children.

If a battery is swallowed, seek medical help immediately.

Batteries contain materials that can harm the environment if disposed of improperly. Recycling of batteries is the preferred method of disposal. Many states require sellers of batteries to accept old batteries for recycling.

i When replacing batteries, make sure they are clean and free of lint.

Bulbs

Safe vehicle operation depends on proper exterior lighting and signaling. It is there- fore essential that all bulbs and lamp assemblies are in good working order at all times. Correct headlamp adjustment is extremely important. Have headlamps checked and readjusted at regular intervals and when a bulb has been replaced. See an authorized Mercedes-Benz Light Truck Center for headlamp adjustment.

Practical hints Replacing bulbs

Warning!

Bulbs and bulb sockets can be very hot. Allow the lamp to cool down before chang- ing a bulb.

Keep bulbs out of reach of children.

Halogen lamps contain pressurized gas. A bulb can explode if you: 앫 touch or move it when hot 앫 drop the bulb 앫 scratch the bulb Wear eye and hand protection.

Because of high voltage in Xenon lamps, it is dangerous to replace the bulb or repair the lamp and its components. We recommend that you have such work done by a qualified technician.

Practical hints Replacing wiper blades

Warning!

Front wiper blades

For safety reasons, switch off wipers and remove the SmartKey from starter switch (vehicles with KEYLESS-GO*: Make sure the vehicle’s on-board electronics have status 0) before replacing a wiper blade. Otherwise the motor could suddenly turn on and cause injury.

Warning!

Wiper blades are components that are sub- ject to wear and tear. Change the wiper blades twice a year, preferably in the spring and fall. Otherwise the windows will not be properly wiped. As a result, you may not be able to observe surrounding traffic condi- tions and could cause an accident.

! Never open the hood when the wiper arms are 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. Make sure the wiper blades are properly in- stalled. Improperly installed wiper blades may cause windshield damage. For your convenience, we recommend that you have this work carried out by an authorized Mercedes-Benz Light Truck Center.
