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 sup- ported 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, es- pecially on hills. Always try to use the jack on level surface. Make sure the jack is posi- tioned correctly under the axle housing. Al- ways lower the vehicle onto sufficient capacity jackstands before working under the vehicle.

Warning!

The brush guard is designed solely to en- hance the appearance of the vehicle and help protect grille and head lights from mi- nor mishaps, either on- or off-road. 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.

To help prevent personal injury when open- ing or closing the brush guard, use extreme caution not to trap hands or feet.

The brush guard must be in raised and locked position while driving.

Practical hints Brush guard*

Warning!

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

The wiper with air spoiler should be mounted on the driver’s side For your convenience, we recommend that you have this work carried out by an authorized Mercedes-Benz Light Truck Center.

Removing wiper blades

왘 Fold the wiper arm forward.

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 windshield glass without a wiper blade inserted. Make certain that the wiper blades are properly installed. Improperly installed wiper blades may cause windshield damage.

Information on spare wheel When you replace the vehicle’s tires, you can use the spare wheel as a regular wheel if: 앫 it is not more than six years old 앫 rim and tire are the same model as the

regular wheels

Warning!

G 55 AMG only

Vehicles with different tire dimensions on the front and rear axle: rim and tire size of spare wheel and normal wheel differ. Han- dling will be adversely affected when the spare wheel is used.

Warning!

Do not exceed the maximum speed of 50 mph (80 km/h).

If the spare tire is more than six years old or is not the same model as the regular tires, have the spare tire replaced with a new tire at the nearest Mercedes-Benz Light Truck Center.

Never operate the vehicle with more than one spare tire.

Practical hints Flat tire 왔 Flat tire Preparing the vehicle

왘 Park the vehicle as far as possible from

moving traffic on a hard surface.

왘 Turn on the hazard warning flashers. 왘 Engage the steering wheel lock in the

straight ahead position and set the parking brake.

왘 Move the gear selector lever to P. 왘 Have any passenger exit the vehicle at

a safe distance from the roadway.

왘 Remove the vehicle tool kit (컄 page 283) and the jack (컄 page 284).

왘 Remove the spare wheel from the

spare wheel mounting bracket (컄 page 285).

Warning!

For your safety, remove spare wheel from the spare wheel mounting bracket before undertaking any further steps.

306

Mounting the spare wheel

왘 Prepare the vehicle (컄 page 306).

Lifting the vehicle 왘 Prevent the vehicle from rolling away by blocking wheels with wheel chocks (not included) or other sizable objects.

When changing wheel on a level surface: 왘 Place one chock in front of and one be- hind the wheel that is diagonally oppo- site to the wheel being changed.

When changing wheel on a hill: 왘 Place chocks on the downhill side

blocking both wheels of the other axle.

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 sup- ported 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, es- pecially on hills. Always try to use the jack on level surface. Make sure the jack is posi- tioned correctly under the axle housing. Al- ways 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).

To do so, turn indent 1 to the right in the pump lever until its stop. Never turn release bolt 2 more than one or two revolutions. Hydraulic fluid can otherwise escape.

왘 Place jack on firm ground. 왘 Position jack under the axle housing, so that it is always vertical (plumb-line) as seen from the side, even if the vehi- cle is parked on an incline. Be certain the jack arm is positioned correctly under the axle housing (axle must fall into jack contour).

왘 Jack up the vehicle by pumping (arrow) until the wheel is clear of the ground. Never start engine while vehicle is raised.

Warning!

Always replace wheel bolts that are dam- aged or rusted.

Never apply oil or grease to wheel bolts.

Damaged wheel hub threads should be re- paired immediately. Do not continue to drive under these circumstances! Contact an au- thorized Mercedes-Benz Light Truck Center or call Roadside Assistance.

Incorrect wheel bolts or improperly tight- ened wheel bolts can cause the wheel to come off. This could cause an accident. Make sure to use the correct wheel bolts.

Lowering the vehicle 왘 Using the pump lever, open the lower- ing screw on the jack approximately one turn (컄 page 308). The vehicle is resting fully on its own weight.

왘 Remove the jack.

왘 Tighten the five wheel bolts evenly, fol- lowing the diagonal sequence illustrat- ed (1 to 5), until all bolts are tight. Observe a tightening torque of 97 lb-ft (130 Nm).

Warning!

After use, disassemble pump handle (컄 page 308) and store jack in the des- ignated storage compartment (컄 page 284).

Have the tightening torque checked after changing a wheel as soon as possible. The wheels could come loose if they are not tightened to a torque of 97 lb-ft (130 Nm).

왘 Press the jack piston in again and close

the lowering screw. Store the jack (컄 page 284) and the other vehicle tools (컄 page 283).

왘 After changing the wheel, secure the damaged wheel on the spare wheel mounting bracket (컄 page 286). Make sure the wheel cannot come loose.
