the right direction.
Using a spare tire with a tread pattern
intende d fo r use in a specific direction
When using a spare tire with a tread pattern
intended for use in a specific direction, p lease
note the fo llowing:
- T he direction o f rotation is marked by an a r­
row on the side of the tire.
- If the spare t ire has to be installed in the in ­
correct di rection, use the spare tire only
temporarily since the tire will not be able to achieve its optimum performance character­
ist ics with regard to aquaplaning, noise and
wear.
- We recommend that you pay particular at­
tent ion to this fact during wet weather and
that you adjust your speed to matc h road
condit ions .
- Replace the flat tire w ith a new one and
have it installed o n your ve hicle as soon as
poss ible to restore the handling advantages
of a un id irect iona l tire .

@ Tips
Check carefully to make sure the hook-up
is secure before moving the car up the flat­
bed truck ramp.
Vehicle transport
Whenever you have your vehicle transported,
be sure to note the following:
(D Note
Mount the tie-down chains/cables over the
running surface (circumference) of the
tires. Never secure the vehicle by the axle,
the suspension struts or the front or rear
towline eye. For technical reasons, the
pressure in the suspension struts may
change during the transport and this will
adversely affect vehicle handling.
Lifting vehicle
