— Read and follow the important information
and notes under > page 257.
— Never use the hex socket in the screwdriver
handle or the hex socket wrench with the
ratchet to loosen or tighten the wheel bolts.
This increases the risk of an accident, be-
cause you will not be able to achieve the cor-
rect tightening specification.

rim could hit the brake rotor and damage the
rotor. Work carefully and have a second per-
son help you.
U irectional tires
unidirectional tire profile is identified by arrows
on the tire sidewall that point in the running di-
rection. You must always maintain the specified
running direction. This is necessary to ensure the
tire’s optimal performance in regard to adhesion,
running noise, and friction, and to reduce the risk
of hydroplaning.
To benefit fully from the advantages of the uni-
directional tire design, you should replace faulty
tires as soon as possible and restore the correct
running direction on all of the tires.
» Reinstall any covers on the wheel bolts that
were removed.
» Store the vehicle tool kit in its designated
place.
» If the removed wheel does not fit in the spare
wheel well, store it securely in the luggage
compartment page 86.
» Check the tire pressure on the installed wheel
as soon as possible.
» Correct the tire pressure and store it in the MMI
