Lock-up wheel nuts
The wheels of your vehicle can be made theft-
proof by means of a wheel nut lock. The wheel
nut lock consists of a wheel nut and a plug-on
sleeve with lock. The same lock is used on all
four wheels.
Three keys are supplied. Copies of lost keys
cannot be supplied. Please store separately!
If wheels are to be removed whilst your car is in
the garage, please do not forget to hand over
a key for the lock-up wheel nuts along with the
master key.
To remove the wheel nut lock, take off the
plastic cap, insert the key as far as it will go into
the lock, turn approx. 30° to left and remove
the sleeve with the key.
To fit the wheel nut lock, turn the key back
again 30° to right, remove and slip the sleeve
onto the wheel nut until it is felt to lock in.
Check whether the sleeve is up against the
shoulder of the wheel nut.
Fit the plastic cap.
It is not usually necessary to re-balance the
wheels.
Puncture
When a tyre is punctured, drive as far over to
the offside of the road as possible, and if ne-
cessary turn the hazard warning lights on and
set up a warning triangle at the correct distance
behind the car.
The ground should be firm and level before
jacking up the car. The handbrake must be
firmly applied, and the wheels on the other
side of the car should be blocked with a chock.
For vehicles with manual gearbox, engage
1st gear; for vehicles with automatic gearbox,
engage selector "P". Nobody must be in the
vehicle while it is being jacked up.
