Vehicle jack

Warning!

The vehicle jack is located underneath the cargo 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 the 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 a level surface.

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

Warning!

Preparing the vehicle

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

The Minispare wheel is for temporary use only. When driving with a Minispare wheel mounted, ensure proper tire 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 Minispare 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.

Warning!

Your vehicle is equipped with air suspen- sion. Do not open or close any doors or the tailgate while mounting a spare wheel. The vehicle could rise or lower to a previously se- lected 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 151).

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

왘 Set the parking brake (컄 page 60). 왘 Set the automatic transmission to park

position P (컄 page 194).

왘 Take the wheel wrench, the collapsible wheel chock, and the vehicle jack out of the cargo compartment (컄 page 495).

왘 Take the Minispare wheel out of the

cargo compartment (컄 page 499).

! Vehicles with factory-mounted running-boards*: Your vehicle is equipped with a scissors-type jack (located under the cargo compartment floor) designed for use with factory-mounted running boards. Only use this jack when jacking up vehicles with factory-mounted running boards as otherwise the vehicle’s underbody can be damaged. See separate instructions for scissors-type jack.

Warning!

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 that the jack arm is fully seated in the jack take-up brack- et. Always lower the vehicle onto sufficient capacity jackstands before working under
