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 sub- ject 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. Make sure the wiper blades are properly installed. 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.

Warning!

The dimensions of the spare wheel (Minispare wheel or collapsible tire) are dif- ferent 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 a spare wheel mounted, ensure proper tire pressure and do not ex- ceed 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® when a Minispare wheel is mounted.

Preparing the vehicle

왘 Vehicles with air suspension program*:

Make sure the vehicle level is set to highway (컄 page 257).

Warning!

Vehicles with air suspension program*:

Do not open or close any doors or the tailgate while mounting a spare wheel. The vehicle could rise or lower to a previously selected level. You or others could be injured as a result.

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 141).

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

왘 Set the parking brake (컄 page 57). 왘 Set the automatic transmission to park

position P (컄 page 185).

왘 Turn off the engine (컄 page 39). 왘 Have any passenger exit the vehicle at

a safe distance from the roadway.

i Open door only when conditions are safe to do so. 왘 Vehicles with SmartKey: Remove the

SmartKey from the starter switch. Vehicles with KEYLESS-GO*: Open the driver’s door (this puts the starter switch in position 0, same as with the SmartKey removed 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.

왘 Take the wheel wrench, the collapsible wheel chock, and the vehicle jack out of the cargo compartment (컄 page 448).

Vehicles with collapsible tire (ML 63 AMG only): 왘 Take the collapsible tire, wheel wrench, wheel bolts, jack, and electric air pump out of the cargo compartment (컄 page 454).

! Depending on vehicle production date your vehicle may be equipped with a scissors-type jack (located under the cargo compartment floor). If so equipped, only use this jack when jacking up the vehicle as otherwise the vehicle’s underbody can be damaged. See separate instructions for scissors-type jack.

i Vehicles with collapsible tire (ML 63 AMG only): 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 emergency spare tire (컄 page 485). 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 re- mains to start the engine.

Lifting the vehicle

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- jury, use the jack only to lift the vehicle dur- ing a wheel change.

Never get beneath the vehicle while it is sup- ported by the jack. Keep hands and feet away from the area under the lifted vehicle. Always lower the vehicle onto sufficient capacity jackstands before working under the vehicle.
