Preparing the vehicle

WARNING
You must remove the spare wheel from the spare wheel carrier before lifting the vehicle.

Otherwise the vehicle could fall off the jack and injure you or others.

Prepare the vehicle as described .

Remove the vehicle tool kit and the jack .

Secure the vehicle to prevent it from rolling away.

Remove the spare wheel from the spare wheel bracket .

Vehicles without a spare wheel or emergency spare wheel are not equipped with a tire-change tool kit at the factory. For more information on which tools are required to perform a wheel change on your vehicle e.g. lug wrench or jack, consult an authorized Mercedes-Benz Center.

Securing the vehicle to prevent it from rolling away

On level ground:

place chocks or other suitable items under the front and rear of the wheel that is diagonally opposite the wheel you wish to change.

On downhill gradients:

place chocks or other suitable items in front of the wheels of the front and rear axle.

Raising the vehicle

WARNING
If you do not position the jack correctly at the appropriate jacking point of the vehicle, the jack could tip over with the vehicle raised.

There is a risk of injury.

Only position the jack at the appropriate jacking point of the vehicle. The base of the jack must be positioned vertically, directly under the jacking point of the vehicle.

The jack is designed exclusively for jacking up the vehicle at the jacking points.

Otherwise, your vehicle could be damaged.

The following must be observed when raising the vehicle:
Х to raise the vehicle, only use the vehiclespecific jack that has been tested and approved by Mercedes-Benz. If used incorrectly, the jack could tip over with the vehicle raised.

Х the jack is designed only to raise and hold the vehicle for a short time while a wheel is being changed. It is not suited for performing maintenance work under the vehicle.

Х avoid changing the wheel on uphill and downhill slopes.

Х before raising the vehicle, secure it from rolling away by applying the parking brake and inserting wheel chocks. Never disengage the parking brake while the vehicle is raised.

Х the jack must be placed on a firm, flat and non-slip surface. On a loose surface, a large, load-bearing underlay must be used. On a slippery surface, a non-slip underlay must be used, e.g. rubber mats.

Х do not use wooden blocks or similar objects as a jack underlay. Otherwise, the jack will not be able to achieve its loadbearing capacity due to the restricted height.

Х make sure that the distance between the underside of the tires and the ground does not exceed 1.2 inches (3 cm).

Х never place your hands and feet under the raised vehicle.

Х never lie under the raised vehicle.

Х never start the engine when the vehicle is raised.

Х never open or close a door or the tailgate when the vehicle is raised.

Х make sure that no persons are present in the vehicle when the vehicle is raised.

► Using lug wrench 1, loosen the bolts on


Using lug wrench 1, loosen the bolts on the wheel you wish to change by about one full turn. Do not unscrew the wheel bolts completely.

Pump lever

2 Notch on pump lever

Assemble the pump lever for the jack. It can be found with the vehicle tool kit .

► Turn pressure release screw 3 clockwise


Turn pressure release screw 3 clockwise as far as it will go using notch 2 on the pump lever.

Pressure release screw 3 is closed.

Do not turn pressure release screw 3 by more than one to two revolutions.

Otherwise, hydraulic fluid could escape.

► Set jack 1 on solid ground.


Set jack 1 on solid ground.

Position jack 1 on the axle carrier tube 2 of the front or rear axle. Jack 1 must always stand vertically, even on slopes.

Make sure that jack 1 is correctly positioned under axle carrier tube 2. The front or rear axle must sit securely in the recess of jack 1.

Raise the vehicle by pumping in the direction of the arrow, until the tire is a maximum of 1.2 in (3 cm) off the ground.

Removing a wheel

Do not place wheel bolts in sand or on a dirty surface. The bolt and wheel hub threads could otherwise be damaged when you screw them in.

Unscrew the wheel bolts.

Remove the wheel.

Mounting a new wheel

WARNING
Always replace wheel bolts that are damaged or rusted.

Never oil or grease wheel bolts. This could cause the bolts to loosen in the wheel hub.

WARNING

Never apply oil or grease to wheel bolts.

Damaged wheel hub threads should be repaired immediately. Do not continue to drive under these circumstances! Contact an authorized Mercedes-Benz Center or call Roadside Assistance.

Incorrect wheel bolts or improperly tightened wheel bolts can cause the wheel to come off.

This could cause an accident. Make sure to use the correct wheel bolts.

WARNING

Only use genuine Mercedes-Benz wheel bolts.

Other wheel bolts may come loose.

Do not tighten the wheel bolts when the vehicle is raised. Otherwise, the vehicle could fall off the jack.

To prevent damage to the paintwork, hold the wheel securely against the wheel hub while screwing in the first wheel bolt.

Always pay attention to the instructions and safety notes in the "Changing a wheel" section .

Clean the wheel and wheel hub contact surfaces.

Place the new wheel on the wheel hub and push it on.

Tighten the wheel bolts until they are finger-tight.

Lowering the vehicle

WARNING
The wheels could work loose if the wheel nuts and bolts are not tightened to the specified tightening torque. There is a risk of accident.

Have the tightening torque immediately checked at a qualified specialist workshop after a wheel is changed.

► Open the pressure release screw on the


Open the pressure release screw on the jack using the pump lever  by approximately one turn.

Lower the vehicle until it is once again standing firmly on the ground.

Place the jack to one side.

Tighten the wheel bolts evenly in a crosswise pattern in the sequence indicated (1 to 5). The specified tightening torque is 96 lb-ft (130 Nm).

Disassemble the pump lever.

Push the jack piston back in and close the drain plug.

Use the bolts to secure the faulty wheel to the spare wheel bracket .
