& WARNING
• Always observe the warnings in:::::, page 290, "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 S 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
authorized Audi dealer or a qualified workshop. Drive slowly and
avoid sudden, hard brake applications.
• Canada models: If the brake warning light((]:» and the ABS
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 imme­
diately by your authorized Audi dealer or a qualified workshop.

A malfunction in the engine cooling system must be
repaired as soon as possible.
When the -L symbol in the display blinks, then either the
engine coolant
temperature is too high, or the coolant level
is too low. An additional driver message can also be displayed
by pressing the [CHECK] button:
Switch off engine and check coolant level
- Pull off the road .
- Stop the vehicle.
- Turn off the engine.
- Check coolant level :::>

-Add coolant if necessary=> page 310.
-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.
If the O warning symbol (alternator malfunction) also lights up on
the instrument panel:::::,

_________________________________________ I_ n_ t_ e_ ll_,igent technology ,__E~-
If an individual wheel begins to rotate too slowly in relation to vehicle
speed and tends to lock, the ABS automatically reduces brake pres­
sure to prevent that wheel from locking .
Thi s automatic adjustment process wi ll cause a
slight vibration of
the brake pedal and some noises to alert you that vehicle speed must
be adapted to existing road and traffic conditions.
_& WARNING
Although the ABS is very effective, always remember that braking
capability is limited by tire traction. Always adjust your driving
speed according to the road and traffic conditions. Do not let the
extra safety afforded by the ABS tempt you into taking extra risks.
The ABS cannot overcome the laws of physics .
(I) Tips
• If ABS is not funct ioning properly, a warning light will come on .
See ~
page 19.
• If a fault occurs in the ABS, the EDL is also not functioning. This is
ind icat ed by the ABS warning light. •
Brake assistant
The brake assistant is designed to achieve the optimum
braking effect.
The brake assistant helps to increase the effective braking power and
thus to achieve a shorter stopping distance.
If the driver presses the
brake peda l very qu ickly , the brake assistant automatically boosts the
braking force to the maximum level, up to the point where the anti­
lock brake function (ABS) intervenes to stop the whee ls from locking.
You should then keep the brake pedal pressed until the vehicle has
braked to the required speed. The brake assistant switches itself off
as soon as you release the brake pedal.
Controls and equip­ ment Safety first Vehicle operation
Automatic full braking
assist
This function allows full braking in spite of high brake pedal forces
(e .g . when the brakes are severely stressed because the veh icle is fully
loaded). The driver notices this function through a reduction of pedal
force and increased pedal travel. When the brake pedal is released,
full braking assist switches off again automatically.
If there is an ABS failure, the brak e assistant and automatic full
braking assist are not available.
Th e brake assistant will not be operative if there is a ma lfunction in
the ABS .
_& WARNING
Please remember that the accident risk always increases if you
drive too fast, especially in corners or on a slippery road, or if you
follow the vehicle ahead of you too closely. Increased risk of an
accident cannot be compensated for even by the brake assistant ,
so always maintain a safe speed.•
Servotronic® -advanced power
steering system
The power steering systems uses the power of the
running engine to allow precise steering with little effort.
The advanced Servotronic ® power steering system senses the road
speed and electronically adjusts power assistance to provide
comfortable and safe steering response exactly matched to the
vehicle speed .
Power steering will not work if the engine is off. As a result , the
steering wheel will be hard to turn .
Th e power steering fluid level is checked during the scheduled main­
tenance services.

Intelligent technology
'-------------------------------------------------
Take into consideration that when you unlock your vehicle, some
convenience functions, such as the remote key or power seat adjust­
me nt, may not be available. The convenience functions will be avail­
able again when you turn on the ignition and start the engine.
With the engine turned off
If you listen to the radio, for example, with the engine turned off or
use other MMI functions, the battery is being discharged.
If start ing capability is jeopardized due to energy consumption, the
following warning appears in the MMI display:
Please start engine, otherwise system will switch off in
3 minutes .
The warning indicates that the system will be turned off automati­
cally after 3 minutes. If you wish to continue using the functions, you
have to start the engine.
With the engine running
Although electrical energy is generated when the vehicle is being
driven, the battery can become discharged. This happens mostly
when little energy is being generated and a great deal consumed and
the battery's state of charge is not optimal.
To bring the energy balance back into equilibr ium, consumers which
require especially large amounts of energy are temporarily cut back
or switched off. Heat ing systems in particular require a great deal of
energy. If you notice, for example, that the heated seats* or the
heated rear window are not heating, they have been temporarily cut
back or switched off. These systems will be available again as soon as
the energy balance has been restored .
You will also notice that engine idle speed has been increased
slightly. This is norma l and not a cause for concern. By increasing
engine idle speed the additional energy required is generated and the
battery is charged.
Driver notification in the instrument
cluster display
If battery power drops into the range where it can limit the ability of
the engine to start, this is shown in the instrument cluster display
with the following driver message:
i...-3 Low battery charge: battery will be charged while driving
This notification reminds you that the starting capability of the
engine may be limited. As soon as you start driving again, the battery
w ill be recharged and the notification will go out.
Driver notification appears and goes out again
If th is driver notification appears after the ignition is turned on or
whi le driving and it goes out again after a while, the battery has been
adequately recharged.
Driver notification appears and does not go out
again
If this driver notification appears after the ignition is turned on o r
wh ile driving and does not go out again, the battery's state of charge
is not in the optimal range. Starting ability is restricted. Have the
battery checked as soon as possible by an authorized Audi dealer or
qualified workshop. •
