Safety belts
General notes
Always wear safety belts!
Wearing safety belts correctly saves lives!
This chapter explains why safety belts are nec­
essary, how they work and how to adjust and
wear them correctly.
~ Read all the information that follows and
heed all of the instruc tions and WARNINGS.
A WARNING
Not wearing safety belts or wearing them
improperly increases the risk of serious
personal injury and death.
- Safety belts are the single most effective
means available to reduce the risk of se­
rious injury and death in automobile acci­
dents. For your protection and that of
your passengers, always correctly wear
safety belts when the vehicle is moving.
- Pregnant women, injured, or physically
impaired persons must also use safety
belts. Like all vehicle occupants, they are
more likely to be seriously injured if they
do not wear safety belts. The best way to
protect a fetus is to protect the mother -
throughout the entire pregnancy.
Number of seats
Your Audi has a total of five seating positions:
two in the front and three in the rear. Each
seating position has a safety belt.
A WARNING
Not wearing safety belts or wearing them
improperly increases the risk of serious
personal injury and death.
- Never strap more than one person, in­
cluding small children, into any belt. It is
especially dangerous to place a safety
belt over a child sitting on your lap.
- Never let more people ride in the vehicle
than there are safety belts available.
Safety belts 149
-Be sure everyone riding in the vehicle is
properly restrained with a separate safe­
ty belt or child restraint.
Safety belt warning light
Your vehicle has a warning system for the
driver and (on USA models only) front seat
passenger to remind you about the impor­
tance of buckling-up.
Fig. 154 Safety belt warning light in the instrument
cl uster -enla rged
Before driving off, always:
~ Fasten your safety belt and make sure you
are wearing it properly.
~ Make sure that your passengers also buckle
up and properly wear their safety belts.
~ Protect your children with a child restraint
system appropriate for the size and age of
the children.
The warning light . in the instrument cluster
light s up when the ignition is switched on as a
reminder to fasten the safety belts. In addi­
tion, you will hear a warning tone for a certain period of time.
Fasten your safety belt now and make sure
that your passengers also properly put on
their safety belts.
A WARNING
- Safety belts are the single most effective
means available to reduce the risk of se­
rious injury and death in automobile acci­
dents. For your protection and that of
your passengers, always correctly wear safety belts when the vehicle is moving.

198 Intelligent technology
Dynamic ste ering *
On vehicles with dynamic stee ring* , ES C helps
stabilize the st eering in critical s ituations .
Selective wh eel torque c ontrol
The selective whee l torque control operates
when dr iv ing through curves . T he front wheel
on the inside of the curve or both wheels on
the inside of the curv e are braked selective ly
as needed. This m inimizes sliding in the front
wheels and allows for more pr ecise driving
through curves . T he system may not act ivate
when driving in wet or snowy cond itions .
A WARNING
-ESC, ABS, ASR, EDL dynamic steering"
and the se lective wheel torque control
cannot overcome the laws of physics .
Th is is especially important on slippery
or wet roads.
If the systems begin act ing
to stabilize yo ur vehicle , you sho uld im­
med iately change your speed to ma tch
the road and traffic condit ions. Do not
let the increased safety provided by
these systems tempt you to take risks. Do ing so wi ll increase the risk of a loss of
vehicle control, collision and serious per­
sonal injuries .
- Always adapt your speed to road, traff ic
and weather condit ions. The risk of Los-
ing cont ro l of the veh icle increases when
Switching on/off
-
driving too fast, espec ially through
curves and on slippery or wet roads, and
when dr iv ing too close to vehicles up
ahead . ESC, ABS, the brake ass ist sys­
tem, ASR, ED L, dynam ic steering* and
the selective whe el torque cont ro l can­
not p revent collisions.
- Always accelerate with special care on
even, smooth surfaces such as those that
are wet or covered with ice and snow.
The drive wheel s can spin eve n w ith
these assistance sys tems t hat can not al ­
ways he lp to red uce the risk of loss of ve­
hicle control.
(0 Tips
- ABS and ASR only work correctly when
all four whee ls are equipped wi th identi ­
cal tires . Different tire sizes can lead to a
reduction in engine powe r.
- Yo u may hear noises when the systems
described are working .
-If the ind icator light&] or llB (USA
mode ls)/ [iJ (Canada models) appears,
there may be a malfunction

iT-ij Dynamic steering: System fault! You can
cont inue driving
If the indicator light turns on and the mes­
sage appears, the steer ing may be more diffi­
cult to move or more sensitive than usual. The
steering may also be at an angle when driving
straight.
Drive slow ly to your authorized Audi dealer or
qualified workshop to have the malfunction
corrected .
iT-ij Dynamic steering: Initializing
Audi drive select*: if the indicator light blinks
and the driver message appears, the dynamic
steer ing* is reinitialized. Once you sta rt the
engine after this is finished, the steering
wheel will be easy to move. Re-ini tialization
might be necessary if the steering wheel was
moved hard to the left and right while the ve­
h icle was not moving . The display turns off if
the initiali zation was successful.
- If the . or
tTij indicator light on ly stays
on for a short time, you may continue
driving.
- The dynamic steering* stability systems

Driving with your
quattro
With all-wheel drive, all four wheels are driv­
en.
General information
W ith all-wheel dr ive, power is distributed to
all four wheels. This happens automatically
depending on your driving sty le and the road
conditions at the time . See also ¢
page 197.
A center different ial distr ibutes the dr iv ing
power var iably to the front and rear axle . It
works together with se lective wheel torque control, which activates when driving through
curves
r=:>
page 198.
The all-wheel drive concept is designed for
high eng ine power. Your veh icle is except ion ­
ally powerfu l and has excellent driving charac­
teristics both under normal driving conditions
and on snow and ice . Always read and follow
safety precaut ions r=;,
,&.
Winter tires
When driving in the winter, your vehicle with
all-wheel drive has an advantage, even with
regular tires. In winter road conditions it may
be advisable to mount winter tires (or all-sea­
son tires) for improved driveability and brak­
ing : these tires must be mounted on
all four
wheels.
See also r=;, page 262, Winter tires.
Tire chains
Where tire chains are mandatory on certain
roads, this norma lly also app lies to veh icles
with all-wheel driver=;,
page 263, Snow
chains .
Replacing wheels/tires
Vehicles with a ll-wheel drive must always
have tires of the same size. A lso avoid tires
with different tread depths. For deta ils see
page
r=;, page 2 SB, New tires and replacing
tires and wheels.
A WARNING
-Always adjust your dr iv ing to road and traf-
f ic conditions. Do not let the extra safety
afforded by all-wheel drive tempt you into
taking extra risks .
- Although the all-wheel drive is very ef­
fective, always remember that braking
capacity is lim ited by tire traction. You
should therefore not drive at excessive
speeds on icy or slippery road surfaces.
- On wet road surfaces, be careful not to
drive too fast because the front wheels
could begin to slide on top of the water
(aquaplaning). If this should occur, you
will have no warning from a sudden in­ crease in eng ine speed as w ith a front­
wheel drive veh icle. Always drive at

Cold tire inflation pressure
Tire pressure affects the overall handling, performance and safety of a vehicle.
Fig. 205 Tire press ure label: located on driver 's s ide B·
p ill ar
Tire pressure generally refers to the amount
of air in a tire that it needs it to do its job and
safely carry the combined load of the entire
vehicle and its contents . Tire pressure is
measured in kilopasca ls (kPa), the interna­
tional measuring unit and in pounds pe r
square inch (PSI). Tire pressure is based in
part on the vehicle 's design and load limit -
the greatest amount of weight that the vehi­
cle can carry safe ly and the t ire size . The prop­
er tire pressure is frequent ly referred to as the
"recommended cold tire inflation pressure."
Air in the tires expands when the tire heats up
because of internal friction when it flexes in
use . The tire pressu re is higher when the tire
has warmed up than when it is "cold ."
It is the
in flat ion pressure i n a "cold " tire that counts.
Therefo re, you shou ld neve r let air out of a
warm tire to ma tch "cold tire inflat ion pres­
sure" recommendations. The tires would then
be underinflated and could fail suddenly .
Maintaining proper tir e pressure is one of the
most impor tant things you can do to help
avoid sudden tire failure. Underinflated tires
are a ma jor cause of s udden tire failure . Keep·
ing tires at the right pressure is also impor­
tant for safe and responsive vehicle handling,

traction, braking and load carrying. Tire pres­
sures are particularly important when the
vehicle is being driven at higher speeds, and
then especially when heavily loaded even
within the permissible load-carrying capaci­
ties approved for your vehicle.
The recommended tire pressures for your Audi
depend on the kind of tires on your ve hicle
and the number of passengers and/o r amount
of luggage you w ill be transporti ng.
The tire pressure label is located on the driv­
er's side B -pillar . The tire pressure labe l lists
the recommended cold tire inflat io n pressures
for the vehicle at its maximum capacity
weight and tires that were on your veh icle at
t he time it was manufactured.
If you wish to improve comfort when operat­
ing the vehicle at normal load (up to 3 occu­
pants), you can adjust tire pressures to those
specified for normal vehicle load. Before op­
erating the vehicle at maximum load, you
must increase the tire pressures to those
specified for maximum vehicle load

Because technical changes may be made to
vehicle equ ipment dur ing the model year, a l­
ways compare the tire size designation on the
tire pressure labe l on you r veh icle w it h the
tires on your vehicle. Ma ke su re that the tire
size info rmation on the vehicle label is the
same as the size of the tires on the vehicle.
This is especia lly important if the vehicle be­
longs to someone else or you bought the vehi- cle w
ith different rims/t ires or you bought the
vehicle as a prev iously owned vehicle.
Remember, your safety and that of your pas ­
sengers also depends on making sure that
load lim its are not exceeded. Vehicle load in­
cludes eve rybody and everyth ing in and on the
vehicle. These load l imits a re techn ica lly refer­
red to as the vehicle's Gross Vehicle Weight
Rating ("GVWR"). The Gross Axle Weight Rat­
ing ("GAWR") is the maximum load that can
be applied at each of the vehicle's two axles . .,_

258 Tires and wheels
Incorrect wheel alignment
Incorrect wheel alignment can cause exces­
sive 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 always have tires
of the same size, construction and tread type.
For details see Qpage 202 .
.&_ WARNING
Sudden tire failure can lead to loss of con­
trol, a crash and serious personal injury!
- Never drive a vehicle when the tread on
any tire is worn down to the wear indica­
tors.
- Worn tires are a safety hazard, they do
not grip well on wet roads and increase
your risk of"hydroplaning" and loss of
control.
- Always keep chemicals that can cause
tire damage, such as grease, oil, gasoline
and brake fluid away from tires.
- Tires age even if they are not being used
and can fail suddenly, especially at high
speeds. Tires that are more than 6 years
old can only be used in an emergency
and then with special care and at lower
speeds.
- Never mount used tires on your vehicle if
you a re not sure of their "previous histo­
ry." Old used tires may have been dam­
aged even though the damage cannot be
seen that can lead to sudden tire failure
and loss of vehicle control.
New tires and replacing tires and wheels
New tires and wheels have to be broken in .

The tires and rims are essential parts of the
vehicle's design . The tires and rims approved
by Audi are specially matched to the charac­
teristics of the vehicle and can make a major .,..

-All four wheels must be fitted with radial
tires of the same type, size (rolling cir­
cumference) and the same tread pattern .
Driving with different tires reduces vehi­
cle handling and can lead to a loss of
control.
- If the spare tire is not the same as the
tires that are mounted on the vehicle -
for example with winter tires -only use
the spare tire for a short period of time and drive with extra care. Refit the nor­
mal road wheel as soon as safely possi­
ble.
- Never drive faster than the maximum
speed for which the tires on your vehicle
are rated because tires that are driven
faster than their rated speed can fail
suddenly.
- Overloading tires cause heat build-up,
sudden tire failure, including a blowout
and sudden deflation and loss of control.
- Temperature grades apply to tires that
are properly inflated and not over or un­
derinflated .
- For technical reasons it is not always
possible to use wheels from other
vehicles -in some cases not even wheels
from the same vehicle model.
- If you install wheel trim discs on the ve­
hicle wheels, make sure that the air flow
to the brakes is not blocked. Reduced air­
flow to the brakes can them to overheat,
increasing stopping distances and caus­
ing a collision.
- Run flat tires may only be used on
vehicles that were equipped with them at the factory. The vehicle must have a
chassis designed for run flat tires. Incor­
rect use of run flat tires can lead to vehi­
cle damage or accidents. Check with an
authorized Audi dealer or tire specialist
to see if your vehicle can be equipped
with run flat tires. If run flat tires are
used, they must be installed on all four
wheels . Mixing tire types is not permit­
ted.
Tires and wheels 261
@ Note
- For technical reasons, it is not generally
possible to use the wheel rims from oth­
er vehicles. This can hold true for wheels
of the same vehicle type.
- If the spare tire is different from the
tires that you have mounted on your ve­
hicle (for example winter tires or wide
profile tires), then use the spare tire for a
short period of time only and drive with
extra care. Replace the flat tire with the
tire matching the others on your vehicle
as soon as possible.
- Never drive without the valve stem cap .
The valves could get damaged.
(® For the sake of the environment
Dispose of old tires in accordance with the
local requirements.
Uniform tire quality grading
- Tread wear
- Traction AA A B C
- Temperature ABC
Quality grades can be found where applicable
on the tire side wall between tread shoulder
and maximum section width
¢ page 258,
fig. 209.
For example: Tread wear 200, Traction AA,
Temperature A.
All passenger car tires must conform to Feder­
al Safety Requirements in addition to these
grades.
Tread wear
The tread wear grade is a comparative rating
based on the wear rate of the tire when tested
under controlled conditions on a specified
government test course.
For example, a tire graded 1S0 would wear
one and one half (1 1/2) times as well on the
government course as a tire graded 100. •
