12Warning symbol in instrument cluster
If the symbol
lights up in the display, this means that either the
coolant temperature is too high or the coolant level is too low
⇒ page 33 .
If the needle is at the top end of the dial, this means the coolant
temperature is too high. Stop the vehicle, switch off the engine and
wait for it to cool down. If the warning lamp starts flashing again
after just a short distance, contact a qualified workshop.
WARNING
•
Before opening the bonnet and checking the coolant level,
please observe the warning information on ⇒page 255, “Working
on components in the engine compartment”.
•
Never open the bonnet if you can see or hear steam or coolant
escaping from the engine compar tment; there is a risk of being
scalded. Wait until you can no lo nger see or hear escaping steam
or coolant.Caution
•
Additional lights and other accesso ries in front of the air inlet
reduce the cooling effect of the radiator. At high outside tempera-
tures and high engine loads, there is a risk of the engine over-
heating.
•
The front spoiler also ensures proper distribution of the cooling
air when the vehicle is moving. If the spoiler is damaged this can
reduce the cooling effect, which could cause the engine to overheat.
You should obtain professional assistance.
Rev counter
The rev counter indicates the number of engine revolu-
tions per minute.You should select a lower gear if the engine speed drops below
1500 rpm. The start of the red zo ne on the dial indicates the
maximum engine speed which may be used briefly when the engine
is warm and after it has been run in properly. However, it is advisable
to change up a gear or move the se lector lever to “D” (or lift your
foot off the accelerator) before the needle reaches the red zone.
Caution
Never allow the rev counter needle ⇒page 11, fig. 2 to go into
the red zone on the dial for more than a very brief period: there is a
risk of damaging the engine. The start of the red zone on the dial is
different for some engine versions.
For the sake of the environment
Changing up a gear early will help you to save fuel and minimise
engine noise.

Technical data
Applies to vehicles: with cruise control systemCruise control
The indicator lamp
in the instrument cluster lights up when the
cruise control system is operating.
Anti-lock brake system (ABS)
The warning lamp monitors the ABS and the electronic
differential lock (EDL).The warning lamp
lights up for a few seconds when the ignition
is switched on and while the engine is being started. The lamp goes
out again once the system has run through an automatic test
sequence.
There is a fault in the ABS if:
•
the warning lamp
does not light up when the ignition is
switched on,
•
the warning lamp does not go out again after a few seconds,
•
the warning lamp lights up when the vehicle is moving.
The vehicle can still be braked in the normal way (except that the
ABS control function is out of action). Please take the vehicle to a
qualified workshop as soon as po ssible. For further information on
the ABS ⇒ page 222.
If a fault occurs in the ABS, the ESP warning lamp will also light up.
Fault in the main brake system
If the ABS warning lamp
lights up together with the brake
warning lamp
⇒ page 32 , this indicates a fault in the ABS func-
tion, and possibly a malfunction in the main brake system as well
⇒ .
If there is a malfunction in the brake system the symbol
will light
up in the instrument cluster. Please refer to ⇒page 32 . Fault on the electronic differential lock (EDL)
The EDL works in conjunction with the ABS. If a malfunction should
occur in the EDL, this is indicated by the ABS warning lamp
.
Please take the vehicle to a qualified workshop as soon as possible.
For further information on the EDL ⇒page 222 .
WARNING
•
Before opening the bonnet and ch ecking the brake fluid level,
observe the warning information on ⇒page 255, “Working on
components in the engine compartment”.
•
If the brake warning lamp
should light up together with the
ABS warning lamp
, stop the vehicle imm ediately and check the
brake fluid level in the reservoir. If the fluid level has dropped
below the "MIN" mark you must no t drive on - otherwise there may
be an increased acciden t risk. You should obtain professional
assistance.
•
If the brake fluid level is OK, the fault in the brake system may
have been caused by a failure of the ABS control function. As a
result the rear wheels can lock relatively easily when braking. This
could cause the tail of the vehicle to skid sideways. Drive carefully
to the nearest qualified workshop and have the fault rectified.
Applies to vehicles: with Audi hold assistAudi hold assist
This warning lamp monitors the Audi hold assist function.Audi hold assist helps the driver to keep the vehicle stationary while
the engine is running, for instance on steep gradients, at traffic
lights or in stop-and-go traffic. When the Audi hold assist function
is on, you don't have to keep your foot on the brake to prevent the
vehicle from accidentally rolling away. Once it detects that the
vehicle is stopped, Audi hold assist keeps the vehicle stationary. The
green symbol
in the instrument cluster indicates that the func-
tion is activated. You can now take your foot off the brake pedal.

Electro-mechanical parking brake
This warning lamp monitors the electro-mechanical
parking brake.The warning lamp
lights up when the parking brake is applied
with the ignition on. After the ig nition has been switched off the
lamp will stay on for about 30 seconds. The warning lamp will light
up for about 30 seconds if the parking brake is applied with the igni-
tion switched off.
The warning lamp should go out when the parking brake is released.
If the warning lamp flashes continuously after the parking brake has
been applied , the brake may not be strong enough to hold the
vehicle on a slope. This may be due to the brakes overheating.
Please note the following points:
•
If the gradient is too steep to park the vehicle safely, the display
will show the message Caution: Vehicle parked too steep .
•
In the event of a fault in the parking brake system the symbol
will also appear in the instrument cluster display together with the
message Parking brake! You should have the fault corrected by a
qualified workshop without delay.
Brake system
The warning lamp flashes if the brake fluid level is too low

If the brake warning lamp does not go out, or if it lights up
when driving, the brake fluid level in the reservoir is too low – this
may cause an increased accident risk. Stop the vehicle and do not
drive on. You should obtain professional assistance.
•
If the brake warning lamp lights up together with the ABS
warning lamp, this can mean that the control function of the ABS
is out of action. As a result the rear wheels can lock relatively
easily when braking. This could caus e the tail of the vehicle to skid
sideways. Drive carefully to the nearest qualified workshop and
have the fault rectified.

Doors and windows
42Doors and windowsCentral locking systemDescriptionThe vehicle can be locked and unlocked via the central locking
system. You can use any of the following:•
Remote control key ⇒page 47
•
Door handles in conjunction with advanced key* ⇒page 47
•
Lock on driver's door ⇒page 48
•
Interior central locking switch ⇒page 49
Unlocking one side of the vehicle only
When you lock the vehicle, the central locking system will lock the
doors and the boot lid. When you unlock the vehicle, the central
locking system will unlock either the driver's door only, or all the
locks on the vehicle, depending on the setting you have selected on
the sound system or MMI* ⇒page 50 .
Automatic locking function (Auto Lock)
The Auto Lock function locks the doors and the boot lid when the
vehicle exceeds a speed of about 15 km/h.
The vehicle is unlocked again when the ignition key is removed.
Alternatively, the vehicle can al so be unlocked via the central
locking switch or by pulling one of the inside door handles. The Auto
Lock function can be switched on and off on the sound system or
MMI* ⇒page 50 .
In the event of an accident in which the airbags inflate, the doors
will be automatically unlocked to facilitate access and assistance.
Deadlock mechanism
The central locking system is combined with a deadlock mecha-
nism. Once the vehicle has been locked from the outside, the door handles on the inside are deactivated. This makes it more difficult
to break into the vehicle.
Anti-theft alarm system*
If the anti-theft alarm system senses interference with the vehicle it
triggers an audible and visible alarm.
The anti-theft alarm system switches on automatically when the
vehicle is locked. It switches off automatically if you unlock the
vehicle using the
remote control.
If you unlock the vehicle by inserting the key in the driver's door, the
ignition must be switched on within 15 seconds, otherwise the
alarm will be triggered. On some export versions, the alarm is trig-
gered immediately when you open a door.
To deactivate the alarm, press th e unlock button on the remote
control key or switch on the ignition . The alarm will also switch itself
off when it comes to the end of its cycle.
Switch off the interior monitor and tow-away protection if you wish
to prevent the alarm from being triggered accidentally ⇒page 50 .
Turn signals
The turn signals will flash twice when the vehicle is unlocked and
once when the vehicle is locked. If the turn signals do not flash, one
of the doors, the bonnet or the boot lid is still open.
Accidental lock-out
The central locking system prevents you from being locked out of
the vehicle in the following situations:
•
When the driver's door is open, it cannot be locked together with
the other doors by pressing the central locking switch and then
closing the door ⇒ page 49.
•
On vehicles with advanced key*, the boot lid will be released
again automatically if the remote co ntrol key that was last in use is
left inside the boot when the boot lid is closed ⇒page 51 .

Automatic gearbox
164moving the selector lever either in or out of position P. The lever can
only be moved out of position P when the ignition is on.
R - Reverse gear
When reverse gear is engaged the gearbox automatically selects the
lowest gear ratio.
Reverse gear must only be engaged when the vehicle is stationary
and the engine is idling ⇒.
To move the selector lever to position R, press in the interlock
button and at the same time press the brake pedal. Depending on
the model, one or two reversing lights will come on in selector lever
position R (when ignition is switched on).
N - Neutral
In this position the gearbox is in neutral ⇒.
D - Drive (forwards)
In this position the gearbox auto matically selects the best gear
ratio. This depends on the engine load, the road speed and the
dynamic gear control program (DCP).
Press the brake pedal when moving the selector lever from N to D if
the vehicle is stationary or at speeds below 5 km/h ⇒.
In some situations (such as on mountain roads or when towing a
trailer or caravan) it can be advantageous to switch temporarily to
tiptronic mode ⇒page 166 , so that the gear ratios can be selected
manually to suit the driving conditions.
S - Sport position
Select this position if you wish to take full advantage of the car's
performance. This setting makes use of the engine's maximum
power output. When accelerating the gear shifts will be noticeable.
Press the brake pedal when moving the selector lever from N to S if
the vehicle is stationary or at speeds below 5 km/h ⇒.
WARNING
•
Never move the selector lever to R or P when driving, as this
could cause an accident.
•
In selector position D or S the vehicle must always be held with
the foot brake when the engine is running. This is because an auto-
matic gearbox still transmits powe r even at idling speed, and the
vehicle tends to “creep”. The throttle must on no account be
opened inadvertently (for instan ce by hand from the engine
compartment) when a ge ar is engaged with the vehicle stationary.
The vehicle could otherwise star t moving immediately (in some
cases even if the parking brake is engaged) and possibly cause an
accident.
•
To avoid accidents, apply th e parking brake and put the
selector lever in position P befor e opening the bonnet and working
on the vehicle with the engine running. Please observe the impor-
tant safety warnings ⇒page 255, “Working on components in the
engine compartment”.Note
You can select the sport program for gear changes on vehicles with
Audi drive select* by activating the DYNAMIC mode. There is no S
position on the selector lever.•
Applies to vehicles with tiptronic gearbox:
•
If the lever is moved accidentally to N when driving, release the
accelerator and let the engine speed drop to idling before selecting
D or S again.
•
For the sake of fuel economy (and the environment), the gearbox
ratios on some models are designed so that maximum speed is only
obtained when the selector lever is at position S.
