& WARNING
• USA models : If the BRAKE warning light and the r,i:r warning
light come on together , the rear wheels could lock up first under
hard braking. Rear wheel lock -up can cause loss of veh icle control
and an ac cident. Have your vehicle repaired immediately by your
authorized Audi dealer o r a qualified workshop . Drive slowly and
avoid sudden, hard brake applications .
• Canada models : If the brake warning light ((D) and the ABS
warning light come on together, the rear wheels could lock up
first unde r hard braking . Rear wheel lock -up can cause lo ss of
vehicle control and an accident. Have your vehicle repaired imme­
diately by your authorized Audi dealer or a qualified workshop .
Drive slowly and avoid sudden , hard brake applications.
• If the brake warning /indi cator light does not go out after a few
second s and the parking brake released, or lights up while you are
driving , the flu id level in the brake flu id reser voir 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 repair facility 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 vehi cle .
Do not rely on strained brakes to respond with ma ximum stopping
power in critical situations . You must allow for increased braking
distances . The extra di stance used up by fading brakes could lead
to an ac cident. •

Parking brake Please get to a repair shop
-If this symbol appears when the vehicle is stationary or
after the ignition is turned on, check to see if the parking
brake can be released. Drive to an authorized Audi dealer
or other qualified workshop as soon as possible and have
the malfunction corrected. If the parking brake cannot be opened, then take it to an expert at an authorized Audi
dealer.
- If the symbol appears while you are driving, it is possible
that the traction control or the emergency brake has
malfunctioned. It is possible that the parking brake
cannot be applied. It is also possible that the parking
brake cannot be released after it has been applied. Drive
to an authorized Audi dealer or other qualified workshop
to have the malfunction corrected.
If the ABS system malfunctions, the ABS warning/indicator light illu ­

& WARNING
• Always observe the warnings in => page 263, "Engine compart­
ment ", before opening the hood and checking the brake fluid.
• Driving with low brake fluid is a safety hazard. Stop the car and
get professional assistance.
• USA models: If the
BRAKE warning light and the warning
light come on together, the rear wheels could lock up first under
hard braking . Rear wheel lock-up can cause loss of vehicle control
and an accident. Have your vehicle repaired immediately by your

Engine cooling system malfunction _}_
A malfunction in the engine cooling system must be
repaired as soon as possible.
If the _p_ symbol flashes in the display, either the engine
coolant
temperature is too high or the engine coolant level
is too low. A driver message appears as well to explain the
malfunction in more detail. The driver warning goes out
after about 5 seconds, but it can be brought up at any time
by pressing the [ SET] button again.
Switch off engine and check coolant level
- Pull off the road.
- Stop the vehicle.
- Turn off the engine.
- Check coolant level~
page 278.
- Add coolant if necessary ~ page 279.
Continue driving only after the engine coolant
warning/indicator light goes out.
- Contact your authorized Audi dealer for assistance if
necessary.
If the engine coolant level is correct, then the radiator fan may be
the cause of the malfunction. ...

• .___O_ n_ t_h _e_ r_o _a_ d __________________________________________________ _
When stopping at a traffic signal or stopping in city traffic on vehi­
cles with an automatic transmission, the parking brake can be
applied. The vehicle does not have to be held with the footbrake . The
parking brake eliminates the tendency to creep with a drive range
engaged . As soon as you drive off as usual , the parking brake is
released automatically and the vehicle starts to move.
Starting on slopes
When starting on inclines, the starting assist prevents the vehicle
from unintentionally rolling back . The braking force of the parking
brake is not released until sufficient driving force has been built up
at the wheels .
[ i] Tips
For safety reasons , the parking brake is released automatically only
when the driver's safety belt is engaged in the buckle .•
Starting off with a trailer
To prevent rolling back unintentionally on an incline, do
the following:
- Keep the switch pulled and depress the accelerator . The
parking brake stays applied and prevents the vehicle
from rolling backward.
- You can release the switch once you are sure that you are
developing enough driving force at the wheels by
depressing the accelerator.
Depending on the weight of the rig (vehicle and trailer) and the
severity of the incline, you may roll backwards as you start. You can
prevent rolling backwards by holding the parking brake switch
pulled out and accelerating -just as you would when starting on a
hill with a conventional hand brake. •
Emergency braking
In the event that the conventional brake system fails or
locks.
- In an emergency, pull the switch and continue to pull it to
slow your vehicle down with the parking brake.
- As soon as you release the switch or accelerate, the
braking process stops.
If you pull the switch and hold it above a sp eed of about 5 mph (8
km/h), the emergency braking function is initiated. The vehicle is
braked at all four wheels by activating the hydraulic brake system .
The brake performance is similar to making an emergency stop
=>& .
In order not to activate the emergency braking by mistake, an
audible warning tone (buzzer) sounds when the switch is pulled. As
soon as the switch is released, or the accelerator pedal is depressed,
emergency braking stops.
& WARNING
Emergency braking should only be used in an emergency, when
the normal foot brake has failed or the brake pedal is obstructed .
Using the parking brake to perform emergency braking will slow
your vehicle down as if you had made a full brake application. The
laws of physics cannot be suspended even with ESP and its asso­
ciated components (ABS, ASR, EDS) .
In corners and when road or
weather conditions are bad, a full brake application can cause the
vehicle to skid or the rear end to break away -risking an
accident. •
