pressure label. The tire pressure labe l is lo ­
cated on the driver's s ide B-pillar. The tire
pressure label lists the recommended cold
tire inflation pressures for the vehicle at its max imum capacity weight and the t ires that
were on you r vehicle at the time it was man­

Tie-downs
Applies to vehicles: with tie-downs
The Luggage compartment is equipped with four
tie-downs to secure Luggage and other i tems.
Use the tie-downs to secure your cargo properly
<=> page 118, Loading the luggage compartment.
In a coll is io n, the laws of phys ics mean that even
smaller items that are loose in the vehicle w ill
become heavy m iss iles that can cause serious in­
jury. Items i n the vehicle possess energy which
vary w ith vehicle speed and the weight of the
item . Vehicle speed is the most significant factor .
For examp le, in a frontal coll is ion at a speed of
30 mph (48 km/h), the fo rces acting on a 10-lb
( 4 .5 kg) obje ct are abou t 20 times the normal
weight of the item. This means that the we ight
of the item would suddenly be abo ut
200 lbs . (90 kg). Yo u can imagine the injuries
that a 200 lbs. (90 kg) item flying free ly through
t he passenger compartmen t could cause in a co l­
lision like this.
A WARNING
Weak, damaged or improper straps used to
secure items to t ie-downs ca n fa il during hard
braking or in a collision and ca use serious pe r­
sonal i njury.
- Always use suitable mounting straps and
properly secure items to the tie-downs i n
t h e luggage compartment to help prevent
items from shifting or f ly ing fo rward as dan ­
gerous missiles .
- When the re ar seat bac krest is folded down,
always use suitable mounting s traps and
120
-
properly secure items to the t ie-downs in
the l uggage compartment to help prevent
items from flying forward as dangerous mis­
siles into the passenger compartment .
- Never attach a child safety seat tether strap
to a tie-down.
Reporting Safety Defects
Applicable to U.S.A.
If you believe that your vehicle

Trailer mode
Tire pressure
When tow ing a trailer, inflate the tires of your ve­
hicle to the cold tire pressure listed under " Full
load" on the label located on the driver's side B ­
pillar (visible when the door is open). Inflate
trailer tires to trailer and tire manufacturers'
specifications.
Lights
The headlight settings should be checked with
the trailer attached before driving off . Check to
make sure both vehicle and trailer lights are
working properly.
Safety chains
Be su re trailer safety chains are properly connect­
ed from the trailer to the hitch on the vehicle.
Leave enough slack in the chains to permit turn­
ing corners. When you install safety chains, make
sure they will not drag on the road when you are
driving.
The chains shou ld cross under the trai ler tongue
to prevent it from dropping in case of separation
from the hitch.
Driving instructions
Driving with a trailer always requires extra care
and consideration.
To obtain the best possible handling of vehicle
and trai ler, please note the following:
.. Do not tow a loaded trailer when your car itself
is not loaded .
.. Be especia lly careful when passing other
vehicles.
.. Observe speed limits.
.. Do not drive at the maximum permissible
speed .
.. Always apply brakes early.
.. Monitor the temperature gauge.
Weight distribution
Towing a loaded trai ler with an empty car results
in a highly unstable distribution of weight. If this
cannot be avoided, drive at very low speeds only
to avoid the risk of losing steering control.
182
A "balanced" rig is easier to operate and contro l.
This means that the tow vehicle shou ld be loaded
to the extent possible and permissib le, wh ile
keep ing the trailer as light as possible under the
c ir cumstances. Whenever poss ible, transfer
some cargo to the luggage compartment of the
tow veh icle while observing tongue load require­
ments and vehicle load ing considerat ions .
Speed
The higher the speed, the more difficult it be­
comes for the driver to control the rig. Do not
drive at the maximum permissible speed. Reduce
your speed even more if load, weather or w ind
cond it ions are unfavorab le - particularly when
go ing downh ill.
Reduce veh icle speed
immediately if the trailer
shows the slightest sign of swaying.
Do not try
to stop the swaying by accelerating.
Observe speed limits. In some areas, speeds for
vehicles towing tra ilers are lower than for regular
vehicles.
Always apply brakes early. When dr iving down­
hill, shift into a lower gear to use the engine
braking effect to slow the vehicle. Use of the
brakes alone can cause them to overheat and fail.
Coolant temperature
The coolant temperature gauge¢ page 10 must
be observed carefully. If the needle moves close
to the upper end of the scale, reduce speed im­
med iately and/or turn off the air conditioner .
If the coolant temperature warning light . in
the instrument cluster starts flashing, pull off
the road, stop and let the engine
idle for about
two m inutes to prevent heat build-up .
&_ WARNING
Anyone not properly restrained in a moving
vehicle is at a much greater risk in an acci­
dent. Never let anyone ride in your car who is
not properly wearing the restraints provided
by Audi.

Wheels and Tires
General information
.,.Che ck your tires regularly for
damage (punctures, cuts, cracks
and bulges). Remove foreign ob­
jects from the tire tread.
.,. If driving over curbs or similar
obstacles, drive slowly and ap­
proach the curb at an angle.
.,.Have faulty tires or rims re­
placed immediately.
"'Protec t your tires from oil,
grease and fuel.
.,.Ma rk tires before removing
them so that the same running direction can be maintained if
they are reinstalled .
.,.Lay tires flat when storing and
store them in a cool, dry location
with as little exposure to light as
possible.
(D Note
-Please note that summer and
winter tires are designed for
the conditions that are typical
in those seasons. Audi recom­
mends using winter tires dur­
ing the winter months. Low
temperatures significantly de­ crease the elasticity of summ­
er tires, which affects traction
Wheels
and braking ability. If summer
tires are used in very cold tem­
peratures, cracks can form on
the tread bars, resulting in
permanent tire damage that
can cause loud driving noise
and unbalanced tires.
-Burnished, polished or
chromed rims must not be
used in winter driving condi­
tions. The surface of the rims
does not have sufficient corro­
sion protection for this and
could be permanently dam­
aged by road salt or similar
substances.

New tires or wheels
Audi recommends having all work
on tires or wheels performed by
an authorized Audi dealer or au­
thorized repair facility. These fa­
cilities have the proper knowledge
and are equipped with the re­
quired tools and replacement
parts .
.,.N ew tires do no t yet have the
optimum adhesion properties.
D rive carefu lly and at moderate
speeds fo r the first 350 miles
(500 km) with new tires.
.,. Use tires of the same construc­
tion, size (rolling circumference)
and as close to the same tread
pattern as possib le on all four
wheels.
.,. Do not replace tires individually.
At least replace both tires on the same axle at the same time .
216
.,.A udi recommends that yo u use
Aud i O rig ina l equipment tires . If
you would like to use different t ir es, please note that the ti res
may pe rform differently even if
they are the same size
c:> A -
.,. If you would li ke to equ ip your
vehicle with a tire/rim combina ­
t ion tha t is different from what
was installed at the facto ry, con­
sult with an authorized Audi
dea ler or authorized repa ir facili­
ty before making a purchase
¢ ,&. .
The spare tire* is different from
the regular tires installed on the
vehic le - for examp le, if winter
tires or wide t ires are insta lled -
then only use the spare tire* tem­
porarily in case of eme rgency and
drive carefully wh ile it is in use. It
s h o ul d be rep laced wi th a regular
tire as soon as poss ib le .
On
all wheel drive vehic les, all
four wheels must be equipped
with tires that are the same brand
and have the same construction
and tread pattern so that the
dr ive system is not damaged by
diffe rent tire speeds. For this rea­
son, in case of emergency, only
use a spa re tire* that is the same
circumference as the regular tires . .,.

_& WARNING -
-Only use tire/rim combina­tions and suitable wheel bolts
that have been approved by
Audi. Otherwise, damage to
the vehicle and an accident
could result.
- For technical reasons, it is not
possible to use tires from oth­
er vehicles -in some cases,
you cannot even use tires from
the same vehicle model.
- Make sure that the tires you
select have enough clearance
to the vehicle. Replacement
tires should not be chosen simply based on the nominal
size, because tires with a dif­
ferent construction can differ
greatly even if they are the
same size. If there is not
enough clearance, the tires or
the vehicle can be damaged
and this can reduce driving
safety and increase the risk of
an accident.
-Only use tires that are more
than 6 years old when abso­
lutely necessary and drive
carefully when doing so.
-If you install wheel covers on
the vehicle, make sure they al­ low enough air circulation to
Wheels
cool the brake system. If they
do not, this could increase the
risk of an accident.
Tire wear/damage
Fig. 180 Tire profile: Treadwear indica­
tor
Tire wear
Check the tires regularly for wear.
- Inflation pressure that is too low
or high can increase tire wear
considerably.
-Driving quickly through curves,
rapid acceleration and heavy
braking increase tire wear.
- Have an authorized Audi dealer
or authorized repair facility
check the wheel alignment if
there is unusual wear.
-Have the wheels rebalanced if an imbalance is causing noticeable
vibration in the steering wheel. If you do not, the tires and other
vehicle components could wear more quickly.

A WARNING
Please note the important safe­
ty precautions regarding tire pressure ¢
page 219 and load
limits
¢ page 221.
Tires and vehicle load limits
There are limits to the amount of
load or weight that any vehicle
and any tire can carry. A vehicle
that is overloaded will not handle
well and is more difficult to stop. Overloading can not only lead to
loss of vehicle control, but can al­
so damage important parts of the
vehicle and can lead to sudden
tire failure, including a blowout and
sudden deflation that can
cause the vehicle to crash.
Your safety and that of your pas­ sengers also depends on making
sure that load limits are not ex­
ceeded. Vehicle load includes ev­
erybody and everything in and on
the vehicle. These load limits are
technically referred to as the vehi­ cle's
Gross Vehicle Weight Rating
("GVWR").
The "GVWR" includes the weight of the basic vehicle, all factory in­
stalled accessories, a full tank of
fuel, oil, coolant and other fluids plus maximum load. The maxi­
mum load includes the number of
