A WARNING
- Loose objects in the luggag e compar t­
ment can slide about suddenly and alter
the vehicle's handling characterist ics.
- Loose objects in the passenger compart­
ment can fly forward dur ing abrupt ma­
neuvers or accidents and injure occu­
pants.
- Always store objects in the luggage com­
partment and use suitab le straps, pa rtic­
ularly with heavy objects.
- Whe n you transport heavy objects, a l­
ways remembe r that a change in the cen ­
te r of gravity may result in a change in
the vehicle 's handling characterist ics.

Stee ring re comm endat ion
The ESC helps to stabilize the vehicle by
changing the steering torque.
Selective wheel torqu e control
Select ive wheel torque control is used when
driving on curves . The front wheel on the in­
side of the curve or both wheels on the inside
of the curve are braked selective ly as needed.
This a llows more precise driving in curves.
Automatic post -collisi on brakin g system
The "Automatic post-collision braking system "
can help to reduce the risk of slidi ng and of
other coll is ions afte r an accident. I f the airbag
con tro l modu le detects a collision above ace r­
tain vehicle speed, the vehicle is braked by the
ESC.
The vehicle does not brake automatically if:
- the driver presses the accelerator pedal, or
- the braking force generated by the pressed
brake pedal is greater than the braking force
that would be initiated by the system, or
- the ESC, the brake system or the vehicle
electrical system are not functioning.
A WARNING
-The ESC and its integrated systems can­
not overcome the limits posed by natura l
physical laws. This is especially impor ­
tant on s lippery or wet roads. If the sys-
Switching on/off
Sm art Te chnol og y 189
terns beg in acting to stabilize your vehi­
cle, you should immediately alter your
speed to match the road and traffic con­
ditions . Do not let the increased safety
provided tempt you into taking r isks .
This could increase your risk of a co lli­
SIOn.
- Please note the r isk of a coll is ion increas­
es when driving fast, especially through
curves and on slippery or wet roads, and
when dr iv ing too close to objects ahead.
The ESC and its integrated systems can ­
not a lways prevent collisions -there is
still a risk of accidents!
- Press the accelerator pedal caref ully
when acce lerating on even, slippery sur­
faces such as ice and snow. The drive
wheels can spin even when these control systems are installed and this can affect
driving stability and increase the r isk of a
coll is ion.
@ Tips
-ABS and ASR only function correctly
when all four wheels are equipped w ith
identical tires. Different t ire sizes can
lead to a reduct ion in engine power.
- You may hear noises when the systems
descr ibed are working.
- If the
Bl or [I] indicator light appears,
there may be a malfunction

The ESC is designed to funct ion in levels . De­
pend ing on the level that is selected, the sta­
bilization funct ion of the ESC is lim ited or
swi tched off . The amoun t of stabilization con­

In the follow ing unusual situations it may
make sense to switch the ESC sport mode on
to allow the wheels to sp in:

wall.
The correct tire pressure for the
spare wheel is located on a la­
bel on the driver's side B-pillar.
Because technical changes may
be made to vehicle equipment
during the model year, always
compare the tire size designa­
tion on the tire pressure label on your vehicle with the tires on
your vehicle. Make sure that the tire size information on the ve­
hicle label is the same as the
size of the tires on the vehicle. This is
especially important if
the vehicle belongs to someone else or you bought the vehicle
with different rims/tires or you bought the vehicle as a previ­
ously owned vehicle.
Remember, your safety and
that of your passengers also de­ pends on making sure that load
limits are not exceeded. Vehicle
load includes everybody and ev­
erything in and on the vehicle.
These load limits are

Driving style
Driving fast around curves,
heavy acceleration and hard
braking increase tire wear.
Rotating tires for more even
wear
For all four tires on your vehicle
to have the same service life,
we recommend that the front
and rear tires are rotated ac­
cording to the tire manufactur­
er's suggested tire rotation in­
tervals. Please remember the
following:
-Tire rotation intervals may dif­ fer from the vehicle service in­tervals outlined in your War­ranty
& Maintenance booklet .
-The longer one tire is used in one location on the vehicle ,
the more it wears at certain points; therefore, we recom­
mend that you follow the tire
manufacturer's suggested tire
rotation intervals.
-Vehicles with front-wheel drive experience more tread
wear on the front wheels com­
pared to all-wheel drive (quat­
tro).
-Please rotate ti res as shown
¢ fig. 175.
Tires and wheels 24 7
-Extra care must be taken when rotating direction-specific
tires ¢
page 268.
Wheel balancing
The wheels on new vehicles are
balanced. However, various sit­
uations during everyday driving
can cause them to become un­ balanced, resulting in vibra­
tions you can usually feel
through the steering wheel.
Unbalanced wheels must be re­
balanced to avoid excessive
wear on steering, suspension
and tires. A wheel must also be rebalanced when a new tire is
installed.
Incorrect wheel alignment
Incorrect wheel alignment can
cause excessive tire wear, im­pairing the safety of the vehi­
cle. If tires show excessive
wear, have the wheel alignment checked by an authorized Audi
dealer or qualified workshop.
All-wheel drive
Vehicles with quattro must al­
ways have tires of the same size, construction and tread
type . For details see
¢ page 192 .
