Brake system
BRAKE (USA models) / (CD) (Canada models)
This warning/indicator light illuminates when the brake
fluid level is too low or when there is a malfunction in the
ABS, or when the parking brake is set.
The light illuminates when the ignition is turned on. It goes out after
the engine has been started and the parking brake is fully released.
This indicates that the brake warning light is functioning properly.
If the brake warning light does not light up when the engine is
cranking or the parking brake is applied, there may be a malfunction
in the electrical system. In this case, contact your Audi dealer. If the brake system warning/indicator light flashes, there is a brake
system malfunction.
If the ABS fails, the ABS warning /indicator light (USA
models)/
.J (Canada models) flashes together with the brake system
warning/indicator light:::::,& .
(USA models): If the warning light
BRAKE and the warning light

& WARNING
• USA models : If both the BRAKE warning light and the
warning light come on at the same time, the rear wheels could lock up first under hard braking. Lock-up of the rear wheel brakes
can cause loss of vehicle control and an accident. Have your
vehicle repaired immediately by your authorized Audi dealer or a qualified workshop. Drive slowly and avoid sudden, hard brake
application.
• Canada models: If both the brake warning light CCi)) and the ABS
warning light come on at the same time, the rear wheels could
lock up first under hard braking. Lock-up of the rear wheel brakes
can cause loss of vehicle control and an accident. Have your
vehicle repaired immediately by your authorized Audi dealer or a
qualified workshop. Drive slowly and avoid sudden, hard brake
application
• If the brake warning/ indicator light does not go out after a few
seconds and the parking brake released, or lights up while you are
driving, the fluid level in the brake fluid reservoir is too low. If you
believe that it is safe to do so, proceed immediately at low speed
to the nearest authorized Audi dealer or qualified workshop and have the brake system inspected.
• Always keep in mind that after several brake applications, you
will need greater pressure on the brake pedal to stop your vehicle .
Do not rely on strained brakes to respond with maximum stopping
power in critical situations. You must allow for increased braking
distances. The extra distance used up by fading brakes could lead
to an accident. •

& WARNING
The increased safety afforded by ASR does not mean that you can
take safety risks. Always adapt your driving style to the road
conditions and traffic situation.
[ i J Tips
To ensure that the ASR works properly, all four wheels must be fitted
with identical tires. Any differences in rolling radius of the tires can
cause the system to reduce engine power when this is not desired.

Braking
Generat information
What affects braking efficiency?
Operating conditions and driving habits
The brakes on today's automobiles are still subject to wear,
depending largely on operating conditions and driving habits~& .
On vehicles that are either driven mostly in stop-and-go city traffic
or are driven hard, the brake pads should be checked by your autho­
rized Audi dealer more often than specified in the
Warranty & Main­
tenance booklet.
Failure to have your brake pads inspected can
result in reduced brake performance.
On steep slopes, you should use the braking effect of the engine.
This way, you prevent unnecessary wear on the brake system. If you
Controls and equip­
ment Safety first Vehicle operation
Intelligent technology
must use your brakes, do not hold the brakes down continuously.
Pump the
brakes at intervals.
Moisture or road salt
If you are driving faster than 50 mph (80 km/h) and the windshield
wipers are on, the brake pads will briefly touch the brake discs in
regular intervals so as to improve reaction time when braking on
wet surfaces. You, the driver, will not notice anything .
Under certain conditions, for example, when driving through water
or very heavy rain, or even after washing your vehicle, the braking
effect can be reduced due to moisture (or in freezing conditions ice)
on the brake pads. A few cautious brake applications should dry off
the brake pads or remove any ice coatings .
The effectiveness of the brakes can be reduced when the vehicle is
driven on a salt-covered road and the brakes are not used . Likewise,
you clean off accumulated salt coating from brake discs and pads
with a few cautious applications of the brake~&.
Corrosion
There may be a tendency for dirt to build up on the brake pads and
corrosion to form on the discs if the car is not driven regularly or
only for short trips with little use of the brakes.
If the brakes are not used frequently, or if corrosion has formed on
the discs, it is advisable to clean off the pads and discs by braking
firmly a few times from a moderately high speed~& .
Faults in the brake system
If you should notice a sudden increase in brake pedal travel, then
one of the two brake circuits may have failed~ &.
Low brake fluid level
Malfunctions can occur in the brake system if the brake fluid level is
too low. The brake fluid level is monitored electronically.

Trailer towing
Driving with a trailer
General information
Your Audi was designed primarily for passenger transpor­
tation.
If you plan to tow a trailer, please remember that the additional load
wi ll affect durability, economy and performance.
Trai ler towing not on ly p laces more stress on the vehicle, it a lso ca lls
for more concentration from the driver.
For this reasons, always fo llow the operating and driving instruc ­
tions provided and use common sense. •
Technical requirements
Traile r hit ch
Use a weight -carrying hitch conforming to the gross trailer weight.
The hitch must be suitab le for your vehicle and tra iler and must be
mounted secure ly on the vehicle's chassis at a
technically sound
location . Use only a trailer hitch w ith removable ball mount. A lways
check with the trai ler hitch manufacturer to make sure that you are
using the correct hitch .
Do not use a bumper hit ch .
The hitch must be installed in such a way that it does not interfere
w ith the impact-absorbing bumper system . No modifications
should be made to the vehicle exhaust and brake systems. From
time to time, check that all hitch mount ing bolts remain securely
fastened.
When you are not towing a trailer, remove the trailer hitch ball
mount. This prevents the hitch from causing damage should your
vehic le be struck from behind
=:> & .
Tire pre ssure
When towing a trailer, inflate the tires of your vehic le to the cold tire
pressure listed under "Full load"on the sticker on the right door­
jamb. Inflate trai ler tires to trai ler and tire manufacturers' specifica ­
tions.
Lights
The head ligh t settings should be checked wit h the trai ler attached
before driving off. Have the head lights adjusted as necessary so
t hat you can see the road ahead but not blind oncoming traffic.
Check to make sure both vehicle and trailer lights are working prop ­
erly.
Engin e cool ing sy stem
Towing a t rai ler makes the engine wo rk ha rder . It is important that
the cooling system's performance stands up to the additiona l
strain. Make sure that the coo ling syste m has enoug h fluid.
Traile r br akes
If your traile r is equipped wi th a braking system, check to be sure
that it conforms to al l regu lations.
T he trailer hydraulic brake system must not be directly connected to
the vehic le's hydrau lic brake sys tem.
Safety chai ns
Be sure trailer safety chains are properly connected from the trailer
to the h itch on the vehicle. Leave enough slack in the chains to
permit turning corners. When you install safety chains, make sure
they will not drag on the road when you are driving.
The chains should cross under the trailer tongue to prevent it from
dropping in case of separation from the hitch. _.
