248 Tires and wheels
driving a few yards and correct if neces
sary. Follow the instructions from the
snow cha in manufacturer when doing so.
(D Tips
Where snow chains are mandatory oncer
tain roads, this normally also applies to
vehicles with all wheel drive.
Wheel bolts
Wheel bolts must always be tightened to the
correct torque.
The design of whee l bolts is matched to the
factory installed rims. If different rims are fit
ted, the correct wheel bolts with the right length and correctly shaped bolt heads must
be used. This ensures that wheels are fitted
securely and that the brake system functions
correctly .
In certain circumstances, you may not use
wheel bolts from a different vehicle -even if it
is the same model
¢ page 275.
.&_ WARNING
Improperly tightened or maintained wheel
bolts can become loose causing loss of
control, a collision and serious persona l in
Jury.
- Always keep the wheel bolts and the
threads in the wheel hubs clean so the
wheel bolts can turn easily and be prop
erly tightened.
- Never grease or oil the wheel bolts and
the threads in the wheel hubs. They can
become loose while driving if greased or
oiled, even if tightened to the specified
torque.
- Only use wheel bolts that belong to the
rim being installed.
- Never use different wheels bolts on your
vehicle.
- Always maintain the correct tightening
torque for the wheel bolts to reduce the
risk of a wheel loss . If the tightening tor
que of the wheel bolts is too low, they
can loosen and come out when the veh i- cle
is moving.
If the tightening torque is
too high, the wheel bolts and threads
can be damaged and the wheel can be
come loose.
(D Note
The specified torque for the whee l bolts is
90 ft lbs . (120 Nm) with a tolerance of
± 7,4 ft lbs. (± 10 Nm). Torque wheel bolts
diagonally . After changing a wheel, the
torque must be checked as soon as possi
ble with a torque wrench -preferably by an
authorized Audi dealer or qualified work
shop.
Low aspect ratio tires
Your Audi is factory -equipped with low aspect
ratio tires. These tires have been thoroughly
tested and been se lected specifically for your
model for their superb performance, road feel
and handling under a variety of driving condi
t ions . Ask your authorized Audi dealer for
more details .
The low aspect ratio of these tires is indicated
by a numeral of
55 or less in the tire's s ize
designation . The numeral represents the ratio
of the tire's sidewall height in relation to its
tread width expressed in percentage. Conven
tional tires have a height/w idth rat io of 60 or
more.
The performance of low-aspect-ratio tires is
particularly sensitive to improper inflation
pressure. It is therefore important that low
aspect ratio tires are inflated to the specified
pressure and that the inflation pressure is
regularly checked and maintained. Tire pres
sures should be checked at least once a
month and always before a long trip
¢ page 237, Checking tire pressure.
What you can do to avoid tire and rim
damage
Low aspect ratio tires can be damaged more
easily by impact with potholes, curbs, gul lies
or ridges on the road, particularly if the tire is
underinflated . ..,.
264 Emergency situations
@ Tips
The discharged battery must be properly
connected to the vehicle's electrical sys
tem. When jump starting or charging the
battery, never connect the negative
ground cable to the battery negative post
because the batte ry manager system must
be able to detect the battery 's state of
charge. Always connect the negative
ground cab le to the negative ground post
of the battery manager control unit.
Use of jumper cables
Make sure to connect the jumper cable
clamps in exactly the order described below!

h ide :@ booster battery, @ disc harged vehicle battery
The procedure described below for connecting
jumper cables is intended to provide a jump
start for your vehicle .
Vehicle with discharged battery:
.. Turn off lights and accessories, move lever
of automatic transmission to N (Neutral) or
P (Park) and set parking brake .
Connect POSITIVE(+) to POSITIVE(+)
(red)
.. Remove the cover above the jump start con
nection .
.. Open the red
cover on the positive pole
¢fig. 195.
1. Connect one end of the red positive cable
on the
jump start bolt c::> fig. 196 @
(Bolts under red cover= "positive") of the
vehicle to be started @.
2. Connect the other end to the positive ter-
mina l@ of the booster battery@.
Connect NEGATIVE (-) to NEGATIVE (-)
(black)
3. Connect one end of the b lack negative ca
ble to the negative terminal @of the
booster battery @.
4. Connect the other end to the
jump start
bolt @
(Bolts with hex head= "negative")
of the vehicle to be started ®·
Starting the engine
.. Sta rt the engine of the vehicle with the
booster battery@. Run the engine at a
moderate speed.
.. Start engine with discharged vehicle battery
® in the usual manner .
.. If the eng ine fails to start: do not keep the
starter cranking for longer than 10 seconds .
Wait for about 30 seconds and then try
again .
.. With engine running, remove jumper cables
from both vehicles in the exact
reverse or
der .
.. Close the red
cover on the positive pole .
T he battery is vented to the outside to prevent
gases from entering the vehicle interior . Make
sure that the jumper clamps are well connect
ed with their
metal parts in full contact with
the battery terminals.
A WARNING
--
To avoid serious personal injury and dam
age to the veh icle, heed all warnings and
