can cause loss of vehicle control and an accident . Have your
vehicle repaired immediately by your authorized Audi dealer or a qualified workshop . Dr ive slowly and avoid sudden , hard brake
appli cation .

• 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.
• Please be very careful and always keep in mind that after
several brake applications , you will need greater pressure on the

Driver information system
Parking brake set
The parking brake warning light Brake /((D) (Canada models) illumi ­
nates when the parking brake is set. In addition , a warning tone will
sound after you have driven for longer than 3 seconds and faster
than 3 mph (5 km/h).
L1}. WARNING
• Always observe the warnings in => page 209, "Engine compart­
ment", before opening the engine hood and checking the brake
fluid.
• Driving with low brake fluid is a safety hazard! Stop the car and
get professional assistance.
• If the brake system warning/indicator light illuminates
together with the ABS warning/indicator light, then the ABS system is malfunctioning. The rear wheels could quickly lock up
when you apply the brakes. This could lead to loss of control and
your vehicle could slide! Drive carefully to the nearest authorized
Audi dealer and have the malfunction corrected. •
Engine cooling system malfunction ¾
A malfunction in the engine cooling system must be
repaired as soon as possible.
When the _t symbol in the display flashes, then either the
engine coolant
temperature is too high, or the coolant level
is too low. In addition to the symbol, the following message
also appears in the display:
Switch off engine and check coolant level
-Pull off the road and stop the vehicle.
- Turn off the engine.
- Check coolant level
~ page 225.
-Add coolant if necessary ~ page 225.
-Continue driving only after the engine coolant
warning/indicator light goes out.
- Contact your authorized Audi dealer for assistance if
necessary .
If t he engine coolant lev el is correct, then th e radia tor fan may be
the cause of the malfunction.
If the gene rator warning/indicator light should also illuminate
=> page 18, then the fan belt may be damaged.
L1}. WARNING
• If your vehicle should break down for mechanical or other
reasons, park at a safe distance from moving traffic, turn off the
engine and turn on the hazard warning lights
=> page 57, "Emer­
gency flasher A" .
• Never open the hood if you see or hear steam or coolant
escaping from the engine compartment -you risk being scalded.
Wait until you can no longer see or hear steam or coolant escaping.
• The engine compartment of any vehicle is a dangerous area.
Before you perform any work in the engine compartment, turn off
the engine and allow it to cool. Follow the warning stickers
=> page 209, "Engine compartment" .
0 Note
Do not continue driving if the-~- symbol illuminates. There is a
malfunction in the engine cooling system -you could damage your

brake will overheat the rear brakes, reduce their effectiveness and
cause excessive wear. This could lead to brake failure and an acci­
dent.

[ i] Tip s
• Vehicles w ith manua l transmission : You can at tain the set speed
only if the currently engaged gear allows it and the engine is not
stressed. Shifting to a higher or lower gear promptly will allow the
engine to run smooth ly .
• The cruise control cannot maintain a constant speed when
driving downhi ll. The vehicle will acce lerate under its own weight .
Downshift to a lower gear or use the brakes to s low down. •
Changing speed

On th e road
Change speed in increments of 1 mph (1 km/h) by lightly pressing
the lever . If you keep the lever pressed down, you will a lter your
speed in 5 mph (10 km /h) increments .
You can a lso press the acce lerator pedal down to increase your
speed, e.g. if you want to pass someone. The speed you saved
earlier will resume as soon as you release the accelerator pedal.
I f , however, you exceed your saved speed by 5 mph (10 km/h) for
longer than 5 minutes, the cruise control will turn off temporarily .

• If you have to bring your vehi cle to a stop while on an incline ,
keep the foot bra ke depressed all the way down so that the vehicle
does not start to roll backward . You should never hold the vehicle
using the clutch pedal if you are going to be stopped on an incline.
If you do, the clutch will start to slip when it overheats caused by
the constant overload. This is dangerous because if the vehicle starts to roll backward , you could cause an accident. If the clutch
should start to slip , you will feel the vehicle "jerk" and the selector
lever display will start blinking .
• Before driving down a steep slope , reduce your speed and shift
into a lower gear w ith utiptroni c".
• Do not ride the brakes or apply the brake pedal too often or too
long . Constant braking causes the brakes to overheat and
substantially reduces braking performance , increases braking
distance or causes complete failure of the brake system . •

the vehicle begins to skid, ESP brakes the appropriate wheel auto­matical ly .
The vehicle is stabilized again by the forces acting on the wheel during braking. With an oversteering vehicle (tendency for the rear
end to skid out of the curve), the brake application is mainly at the
front wheel on the outside of the curve, with an understeering
vehicle (tendency to run wide in the curve) at the rear wheel on the
inside of the curve or additionally at the other wheels as needed .
This brake application is accompanied by noises.
ESP works in conjunction with ABS=:>
page 187. If there is ma lfunc­
tion in the ABS, ESP is also inoperative .
Activa ting
The ESP is automatica lly activated when the engine is started, and
it performs a self-test. As soon as the test is completed, the system
is in normal operating mode . With ASR deactivated, or with ESP/ASR
deactivated, pressing the button=>
page 182, fig. 130 returns the
system to normal operation.
D eac tiva ting
ESP should norma lly be activated at all times because this ensures
optimum vehicle stability . Only in certain exceptional cases it does
make sense to deactivate Anti -Slip Regulation (ASR) or the Elec ­
tronic Stability Program !ESP) by pressing the button =:>
page 182,
fig. 130. Both deactivation stages can only be activated from normal
mode.
Dea cti vat ing ASR
Tap the switch . Deactivation is indicated by slow flashing of the ESP
lamp in the instrument c luster. In certain situations (e.g. driving
with snow chains, in deep snow or on loose ground, or when rocking the car free), it may be necessary to deactivate ASR. Deacti ­
vation is effective only up to a speed of about 45 mph (70 km/h). At higher speeds, ASR is switched on again automatical ly in front ­
whee l drive vehicles, deactivation is possible only up to about 30
mph (50 km/h). With all -whee l drive vehicles, ASR is active above

about 45 mph (70 km/h) and deactivated automatical ly below this
speed.
D eac tiva tin g ES P/ASR
Press the button for more than 3 seconds . Deactivation is indicated
by the ESP lamp in the instrument c luster staying on permanently .
This deactivates the E lectronic Stabi lity Program (ESP) in addition to
ASR . No Electronic Stability System operation and no Anti-Slip
Regu lation is availab le across the entire speed range; ASR and ESP
are activated only when the brakes are used for the duration of the
braking action and remain active until a stab le vehicle condition has
been reached. There is no driving situation which requires ESP to be
deactivated, so this should only be done if the driver's skill and the
traff ic situation permit .
& WARNING
• The limi ts of ph ysics ca nnot be suspe nd ed by E SP. E ven in vehi ­
cles w ith ESP, you should always adapt your dr iving to road and
