side B-pillar (visible when the door is open).
Inflate trailer t ires to tra iler and t ire manufac­
turers' specifications.
Lights
Check to make sure both vehicle and trailer
lights are working properly.
Safety chains
Be sure tra iler safety cha ins are properly con­
nected from the trailer to the hitch on the ve­
hicle. Leave enough slack in the chains to per­
mit turning corners. When you install safety
chains, make su re they wi ll not drag on the
road when you are driving.
The chains should cross under the tra ile r
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 poss ible handling of vehicle
and traile r, p lease note the following:
~ Do not tow a loaded tra iler when your car it­
self 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 re­
sults 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.
A "balanced" rig is easier to operate and con ­
trol. This means that the tow vehicle should be loaded to the extent poss ible and permiss i­
ble, wh ile keeping the trailer as light as poss i­
ble under the circumstances . Whenever possi-
Trailer towing 203
ble, transfer some cargo to the luggage com­
partment of the tow vehicle while observing
tongue load requirements and vehicle load ing
considerations.
Speed
T he higher the speed, the mo re difficult it be­
comes for the driver to control the rig. Do not
drive at the maximum permissib le speed. Re­
duce your speed even more if load, weather or
wind conditions are unfavorable -particularly
when going downhill.
Reduce veh icle speed
immediately if the trail­
er 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 trai lers are lower than for
regular vehicles .
Always apply brakes early. When driving
downhi ll, shift into a lower gear to use the en ­
gine braking effect to s low the vehicle. Use of
the brakes alone can cause them to overheat
and fail.
Coolant temperature
The coolant temperatu re gauge <=> page 12
must be observed carefu lly. The coolant tem ­
perature can increase if you drive on long in­
clines in a low gear at high engine speeds. Re­
duce your speed immediately if the LEDs in
the top part of the display turn on.
For more information about indicator lights,
refer to .<=>
page 20.
A WARNING
Anyone not properly restrained in a mov­
ing vehicle is at a much greater risk in an
accident. Never let anyone ride in your car
who is not properly wearing the restraints
provided by Audi.
Trailer towing tips
Important to know
Your vehicle handles d ifferently when towing
a trailer because of the additional weight and ..,.

204 Trailer towing
different weight distribution. Safety, perform ­
ance and economy wi ll greatly depend on how
carefu lly you load your trailer and operate
your rig.
Before you actually tow your trailer, practice
turning, stopping and backing up in a n area
away from traffic. Keep practicing until you
have become comp letely fam iliar with the way
your veh icle-trailer comb ination behaves and
responds.
Backing up is d iff icult and requires practice.
Backing up with a tra iler genera lly requires
steering action opposite to that when back ing
up your veh icle without a trailer.
Maintain a greater distance between your ve­
h icle and the one in front of you. You will need
more room to stop. To compensate for the
trailer, you will need a larger than normal
turning radius.
When passing, remember that yo u cannot ac ­
celerate as fast as you normally would be­
cause of the added load. Make sure you have
enough room to pass. After passing, allow
p lenty of room for your tra iler before chang­
ing lanes aga in.
Avoid jerky starts, sharp turns or rapid lane
changes.
(D Tips
- Do not tow a tra iler dur ing the break-in
period of you r vehicle.
- If you tow a trailer, your Audi may re­
quire more frequent maintenance due to
the ext ra load
¢ page 289.
Parking on a slope
Do not park on a slope with a trailer. If it can­
not be avoided, do so only after doing the fol­
lowing:
Wh en park ing:
.. Apply the foot brake .
.. Have someone place chocks under both the
vehicle and the trailer wheels. ..
With chocks in place, slowly release the
brakes unti l the whee l chocks absorb the
load.
.. Turn the whee ls towards the curb.
.. App ly the parking brake.
.. Select the P selector lever posit ion.
When re starting afte r park ing :
.. App ly the foot brake.
.. Start the engine.
.. Select the D/S se lector lever position.
.. Release the parking brake and s lowly pull
out and away from the wheel chocks .
.. Stop and have someone retr ieve the wheel
chocks .
@ Tips
If you move the selector leve r of the auto­
matic transmission to P befo re applying
the pa rking brake and before bloc king the
whee ls, you may h ave to use more force
la ter to move the lever out of the P posi­
tion .

-If you notice unusual vibra­tion or if the vehicle pulls to one side when driving, al­
ways stop as soon as it is safe to do so and check the
wheels and tires for dam­ age.
(D Note
-Please note that summer and winter tires are de­
signed for the conditions
that are typical in those sea­
sons. Audi recommends us­ing winter tires during the
winter months. Low tem­ peratures significantly de­
crease the elasticity of
summer tires, which affects
traction and braking ability.
Tires and wheels 235
If summer tires are used in
very cold temperatures, cracks can form on the tread bars, resulting in perma­
nent tire damage that can
cause loud driving noise and unbalanced tires. Audi is not
responsible for this type of
damage.
-Burnished, polished or chromed rims must not be used in winter road condi­
tions. The surface of the
rims does not have suffi­
cient corrosion protection
for this and could be perma­
nently damaged by road salt
or similar substances.

Glossary of tire and loading terminology
Accessory weight
means the combined weight (in
excess of those standard items
which may be replaced) of auto­ matic transmission, power
steering, power brakes, power
windows, power seats, radio, and heater, to the extent that
these items are available as fac­
tory-installed equipment (whether installed or not).
Aspect ratio
means the ratio of the height to
the width of the tire in percent. Numbers of 55 or lower indi­
cate a low sidewall for im­ proved steering response and
better overall handling on dry
pavement.
' •

-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 tires as shown
¢ fig. 171.
-Extra care must be taken when
rotating direction-specific
tires
Q page 2 74.
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

Tires and wheels 253
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 193 .
.8, WARNING
Sudden tire failure can lead
to loss of control, 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 haz­ ard, 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.

266 Tire s and wheels
& WARNING
-If the tire pressure warning light ti] in
the instrument cluster turns on, the
pressure in one or more tires is too low.
Reduce the vehicle speed immediately
and avoid any hard steering or braking
maneuvers . Stop as soon as possible,
check the t ire and inflate the tire to the
correct pressure, which is specified on
the tire pressu re label on the veh icle
¢ page 240. Driving with a t ire with low
pressure causes the tire to overheat and
can result in failure of the tire . Low pres ­
sure can a lso have a negative effect on
the driving and braking behavior of the
vehicle.
- The driver is responsible for maintaining
the correct tire pressures. You must
check the t ire pressures regularly.
- Under certain conditions (such as a spor­
ty driving style, winter conditions or un­
paved roads), the pressure monitor ind i­
cator may be delayed .
- Ask your author ized dealer if run-flat
t ires may be used on your vehicle.
- The tire pressure monitoring system can
also stop work ing when there is an ESC
malfunction.
- Using snow chains may result in a system
malfunction.
- The tires with the identification "AO" or
"RO" ¢ page 254 have been matched
with your Audi tire pressure monitoring
system. We recommend that you use
these tires.
- The tire pressure monitoring system can
only mon itor the t ire pressure of the
driving tires . Check the tire pressure of
the spare wheel in the luggage compart­ ment so that if necessary it is ready for
us e.
-
Storing tire pressures
Applies to vehicles: wit h tire press ure mo nitor ing system
A change in tire pressure or a change in tires
must be stored in the system.
The tire pressure is stored in the MMI.
.. Make sure before storing that the tire pres ­
sures of a ll four tires meet the specified va l­
ues and are adapted to the load. Otherwise
the system could malfunction
¢ page 240.
.. Switch on the ignition.
.. Select: the
I MENU I button >Car > Systems*
control button > Service & control > Tire
pressure monitor > Store tire pre ssure >
Yes, store now.
(D Tips
Do not store the tire pressures if snow
chains are installed. Otherwise the system
could malfunction.
