Securing the vehicle against rolling
General information
The vehicle manufacturer recommends to ad‐
ditionally secure the vehicle against rolling
away when changing a wheel.
On a level surface
Place chocks or other suitable objects, for ex‐
ample a rock, in front of and behind the wheel
that is diagonally opposite to the wheel that
you wish to change.
On a slight downhill gradient
If you need to change a wheel on a slight
downhill grade, place chocks and other suita‐
ble objects, for instance a rock, under the
wheels of both the front and rear axles against
the rolling direction.
Preparing the vehicle
▷ Change the wheel as far away as possible
from passing traffic.
▷ Park the vehicle on solid, non-slip and level

▷ Switch on the hazard warning system.
▷ Set the parking brake.
▷ Engage a gear or selector lever position P.
▷ As soon as permitted by the traffic flow,
have all vehicle occupants get out of the
vehicle and ensure that they remain out‐
side the immediate area in a safe place,
such as behind a guardrail.
▷ Depending on the equipment version, get
tools and the emergency wheel from the
vehicle.
▷ If necessary, set up a warning triangle or
portable hazard warning lamp at an appro‐
priate distance.

reach its carrying capacity because of the
restricted height.

ing.
