Risk of injury G
A propeller shaft may fall down and injure you when being removed. Secure the propeller shaft prior to
removal to prevent it from falling, e.g. with the aid of a second person or by tying up the propeller shaft.
Do not turn the vehicle key in the steering lock to the drive position when the front axle is raised. Otherwise
the automatic ASR function may cause uncontrolled braking of the rear wheels may while the vehicle is being
towed. This can cause the vehicle to lose lateral stability and break away.
