Wheel Securing Bolts
If the wheels have to be removed at the workshop, please do not forget to hand over the wrench socket for the wheel securing bolts along with the car key.

The wrench socket for the wheel securing bolts is in the tool box.

To loosen or tighten the wheel bolt with anti-theft protection, a wrench socket with the appropriate coding must be used between the wheel bolt and the wheel-bolt spanner.

  • When positioning the wrench socket, ensure that it engages fully in the teeth of the wheel bolt.

Changing a wheel

Unsafe Stopping

Other vehicles could collide with your vehicle if you are parked in a dangerous position.

  • If you have a flat tire, move a safe distance off the road. Turn the emergency flasher on and use other warning devices to alert other motorists.
  • Do not remain in the car. Someone approaching from the rear may not realize your vehicle is stopped and cause a collision.

Stopping Over Nearby Flammable Matter

Exhaust fumes and the exhaust system are very hot when the engine is running. The exhaust system remains hot for some time after the vehicle is turned off.

  • Do not park your vehicle in areas where the hot exhaust system may come in contact with dry grass, brush, fuel spill or other flammable material.

  • Passengers must not be in the vehicle when it is jacked up.
  • Before you change a wheel, be sure the ground is level and firm. If necessary, use a board under the jack to ensure that the jack does not sink into the ground.
  • Set the parking brake and block the wheels opposite the flat tire on the other side of the vehicle.
  • The jack is only to be used for changing a wheel. Do not use it as a support to work under the car.
  • The car must be jacked up only at the illustrated jacking points.Lifting at any other place may result in personal injury.
