21 8 What do I do no w ?
When removing or installing the wheel,
the rim could hit the brake rotor and dam-
age the rotor. Work carefully and have a
second person help you.
Never use the hexagonal socket in the han-
dle of the screwdriver to loosen or t ighten
the wheel bolts.
- Pull the reversible blade from the screw-
driver before yo u use the hexagonal
socket in the handle to turn the wheel
bolts.
- When mounting tires with
unidirectional
tread design
make sure the tread pat-
tern is pointed the right way
~page 218.
- The wheel bolts should be clean and easy
to tu rn. Check for dirt and corrosion on
the mat ing surfaces of both the whee l
and the hub. Remove all dirt from these
surfaces before remo unti ng the wheel.
Notes on wheel change
Please read the informa t ion ~ page 198, New
tires and replacing tires and wheels,
if you are
going to use a spare t ire which is different
from the tires on your vehicle.
After you change a tire :
- Check the tire pressure on the spare imme-
diately after mountin g.
- Have the wheel bolt tightening torque
che cked with a torqu e wrench as s oon as
pos s ible by your auth orized Audi deal e r or
a qualified service station .
- With steel and alloy wheel rims, the wheel
bolts are correctly tightened at a torque of
90 ft lb (1 2 0 Nm).
- If you notice while changing a tire that the
wheel bolts are corroded and difficult to
turn, then the y should be replaced befo re
you check the t ightening torque .
- Replace the flat ti re with a new one and
have it installed on your veh icle as soon as
possible. Remount the wheel cove r.
Until then , drive with extra care and at re-
duced speed s.
_& WARNING
-
- If you are going to equip your vehicle
with tires or rims which differ from those
which were factory installed, then be
sure to read the information
9 page 198,
New tires and replacing tires and
wheels.
- Always store the tools securely in lug-
gage compartment. Otherwise, in an ac-
cident or sudden maneuver they could fly
forwa rd, causing injury to passengers in
the vehicle.
Tires with unidirectional tread design
Tires with unidirectional tread design must be
mounted with their tread pattern pointed the
right direction.
A unidirectional tire can be identified by ar-
rows on the sidewall ,
wh ich point in the direc-
tion of the rota t ion. You must follow the
specified direction of rota t ion. This is necessa-
ry in order fo r these t ires to develop t heir op-
timum character istics regarding grip, road
noise, wear, and hydrop laning.
