Preparing for a wheel change
WARNING Risk of injury from incorrect positioning of the jack

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

Only position the jack at the appropriate jacking point of the vehicle. The base of the jack must be positioned vertically under the jacking point of the vehicle.
WARNING Risk of injury from vehicle tipping

On slopes, the jack could tip with the vehicle raised.

Never change a wheel on a slope.
Consult a qualified specialist workshop.
WARNING Risk of injury from jack tipping

If you park a vehicle with air suspension, the air suspension may remain activated for up to one hour, even when the ignition is switched off. If you then raise the vehicle with the jack, the air suspension will attempt to adjust the vehicle level.

The jack may tip.

Press the Service button on the air suspension remote control before raising the vehicle.

This prevents automatic readjustment of the vehicle level and prevents it from being raised or lowered manually.

WARNING Risk of accident through using an underlay when changing a wheel

If you use an underlay to drive onto with the inner wheel when changing the outer wheel of twin tires, the inner wheel is placed under a load. The wheel can then not be properly pressed and pulled onto its contact surface.

As a result a wheel could be lost when driving.

Always use the jack for a wheel change.
WARNING Risk of accident through losing a wheel

Oiled, greased or damaged wheel nuts, wheel stud threads or conical spring washers can cause the wheel nuts to loosen.

As a result a wheel could be lost when driving.

Never oil or grease the threads or conical spring washers.
In the event of damage to the threads or conical spring washers, contact a qualified specialist workshop immediately.
Have the damaged wheel nuts, wheel studs or conical spring washers replaced.
Do not drive on.
WARNING Risk of injury through losing a wheel

If you loosen a wheel that is resting on the wheel studs under load, it could drop down or tip.

Only remove the last three wheel nuts when it is clear that the wheel is resting on the wheel studs and is not under load.
NOTE Damage to the chassis due to incorrect raising of the vehicle

Do not raise vehicles equipped with a loading crane or cargo liftgate by using the hydraulic supports.

This would cause damage to the chassis frame.

Use the jack to raise the vehicle.
When changing a wheel observe the following:
  • Only use wheel nuts that are approved for the vehicle.

  • The wheel nuts for steel and light-alloy wheels are different.

  • The wheel nuts for light-alloy wheels on the front and rear axles are different.

  • Wheels with a tyre pressure sensor are furnished with a red ring.

Observe the following notes when raising the vehicle:
  • Make sure that the maximum load capacity for the jack is not exceeded. The maximum load capacity of the jack is stated on the adhesive label affixed to the jack.

  • The jack is designed only to raise the vehicle for a short time, e.g. while a wheel is being changed. It is not suitable for raising and holding the vehicle so that work can be carried out underneath it.

  • Only position the jack at the appropriate jacking point on the vehicle. Make sure that the jack is correctly positioned on the jacking point before raising the vehicle.

  • The jack support point may differ on special bodies. Observe the manufacturer's operating instructions.

  • Secure the vehicle before raising it to prevent it from rolling away, e.g. by applying the parking brake and/or using chocks. Do not release the parking brake while the vehicle is raised.

  • The surface on which the jack is standing must be firm and level. The jack must be placed on an underlay if the surface is not firm.

  • Make sure that the distance between the underside of the wheel and the ground does not exceed 30 mm. The vehicle could otherwise slip off the jack or tip over.

  • Do not change a wheel on an incline. The vehicle could otherwise slip off the jack.

  • Do not place your hands or feet under the raised vehicle.

  • Do not lie under the raised vehicle.

  • Make sure that nobody is in the vehicle when it is raised.

  • When the vehicle is raised do not start the engine and avoid other jolting or shaking of the vehicle. The vehicle could otherwise slip off the jack.

Park the vehicle on a firm and level surface.
Apply the parking brake.
Use chocks to safeguard the vehicle against rolling away.

For further information on tyre pressure, see the "Wheels and tyres" section null.

Manoeuvring and tow-starting/towing away
WARNING Risk of an accident when using the vehicle as working machinery when distance control assistant is activated

If the distance control assistant is activated, the vehicle accelerates or brakes automatically in certain situations.

If you use the vehicle as working machinery with distance control assistant activated, the vehicle may accelerate or brake unexpectedly.

Always deactivate the distance control assistant in this or similar situations.
WARNING Risk of an accident when using the vehicle as working machinery with Active Brake Assist activated

If Active Brake Assist is activated while you are towing your vehicle or using it, e.g. as working machinery, the vehicle may brake automatically.

The wheels could lose grip.

Always deactivate Active Brake Assist in this or similar situations.
WARNING Risk of accident due to malfunctioning compressed-air supply system

If the engine is not running, the power steering and the compressed-air supply systems are inoperative. You will then need to apply significantly more force when steering. The spring-loaded brake cylinder on the parking brake may activate if there is a loss of compressed air and the vehicle may then brake uncontrollably.

This could cause you to lose control of the vehicle.

Always use a tow bar.
Always check the compressed-air supply system is working, e.g. using an external compressed-air source.
NOTE Damage to attachments and add-on equipment when towing

Attachments and add-on equipment can affect the vehicle height and width.

Do not exceed the permissible vehicle height and observe the legal requirements for the country you are currently in.
If the rear of the vehicle is raised for towing away, fold back the wind deflectors.
Drive carefully and anticipate road and traffic conditions. Observe the maximum clearance of underpasses.
NOTE Damage to the transmission and air suspension when towing

If the engine is not running during towing, the transmission may be damaged.
