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. Contact an autho- rized 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.

왔 Replacing wiper blades

Warning!

For safety reasons, switch off wipers and remove 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 subject to wear and tear. Replace 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. For your convenience, we recommend that you have this work carried out by an authorized Mercedes-Benz Light Truck Center. 왘 Remove the SmartKey from the starter

switch. Vehicles with KEYLESS-GO*: 왘 Make sure the vehicle’s on-board

electronics have status 0 (컄 page 41).

Practical hints Flat tire

Warning!

The dimensions of the spare wheel are different from those of the road wheels. As a result, the vehicle handling characteristics change when driving with a spare wheel mounted. Adapt your driving style accord- ingly.

The spare wheel is for temporary use only. When driving with spare wheel mounted, ensure proper tire inflation pressure and do not exceed a vehicle speed of 50 mph (80 km/h).

Drive to the nearest Mercedes-Benz Light Truck Center as soon as possible to have the spare wheel replaced with a regular road wheel.

Never operate the vehicle with more than one spare wheel mounted. Do not switch off the ESP® with a spare wheel mounted.

Preparing the vehicle

왘 Vehicles with AIRMATIC*:

Make sure the vehicle level is set to highway level (컄 page 276).

왘 Park the vehicle in a safe distance from

moving traffic on a hard, flat surface when possible.

왘 Turn on the hazard warning flasher

(컄 page 150).

왘 Turn the steering wheel so that the front wheels are in a straight-ahead position.

왘 Set the parking brake (컄 page 65). 왘 Set the automatic transmission to

position P (컄 page 190).

왘 Turn off the engine (컄 page 66). 왘 Have any passenger exit the vehicle at

a safe distance from the roadway.

i Open doors only when conditions are safe to do so.

왘 Remove the SmartKey from the starter

switch. Vehicles with KEYLESS-GO*: 왘 Turn off the engine by pressing the

KEYLESS-GO* button once (컄 page 66).

왘 Open the driver’s door (this puts the starter switch in position 0, same as with the SmartKey re- moved from the starter switch). The driver’s door then can be closed again.

왘 Remove the KEYLESS-GO*

start/stop button from the starter switch.

i You can use the power outlets, except for the power outlet in the front center console, to operate the electric air pump even when the ignition is switched off, e.g. in order to inflate the collapsible tire (컄 page 499). An emergency shut-off feature ensures that the vehicle’s electrical voltage does not fall below a minimum level. If the voltage drops to this mini- mum level, the power outlets are automatically switched off. This ensures that enough power remains to start the engine.

Lifting the vehicle

Practical hints Flat tire

Preparing the vehicle 왘 Prepare the vehicle as described

(컄 page 492).

왘 Take the wheel wrench and the vehicle

jack from the vehicle tool kit (컄 page 469).

왘 Take the spare wheel from the wheel

well under the cargo compartment floor (컄 page 472).

Warning!

When jacking up the vehicle, only use the jack which has been specifically approved by Mercedes-Benz for your vehicle.

The jack is designed exclusively for jacking up the vehicle at the jack take-up brackets built into both sides of the vehicle. Make sure the jack arm is fully seated in the jack take-up bracket.

The jack is intended only for lifting the vehicle briefly for wheel changes. It is not suited for performing maintenance work under the vehicle. To help avoid personal in-
