& WARNING Risk of injury through incor‐

Vehicles with rear-wheel drive
Only use the middle rod and the pump lever rod
with the largest diameter for the jack as a wheel
wrench extension. Only insert the middle rod on
the wheel wrench, and always as far as it will go.
Otherwise, the rods could bend and deform so
much that they can no longer be used as pump
levers for the jack.
Vehicles with Super Single tyres: if you mount the
spare wheel to the rear axle, do not exceed the
maximum speed of 55 km/h and the maximum
distance of 100 km. Otherwise, the transmission
could be damaged due to the different rotational
speeds of the wheels.
Using the pump lever, slowly turn the lower‐
#
ing screw on the jack approximately one revo‐
lution and carefully lower the vehicle.
Place the jack to one side.
#
Pull the rod with the smallest diameter off the
#
pump lever.
The shortened pump lever serves as a wheel
wrench extension.
Starting with the middle rod, slide the wheel
#
wrench extension as far as it will go onto the
wheel wrench.
