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 .

Lights and vision
68when they are in the service position you will also avoid damaging
the paintwork on the bonnet.•
off - the windscreen wipers will be moved back to their original
position.Caution
Never move the vehicle with the front wiper arms in a raised posi-
tion as they are automatically moved back to their normal park posi-
tion above a speed of 6 km/h. The paintwork on the bonnet may be
damaged as a result.
Note
•
You can also use the service position, for example, if you want to
fix a cover over the windscreen in the winter to keep it clear of ice.
•
The service position is automatically set to off when you operate
the windscreen wiper lever or the road speed exceeds 6 km/h.
Changing wiper blades
Good wiper blades are essential for clear vision.Taking off the wiper blade
– Set the wipers to the service position ⇒page 67 . – Lift the wiper arm away from the glass.
– Press the release button on the wiper blade
⇒fig. 70.
Hold the wiper blade firmly and press it forwards slightly .
– Slide the wiper blade upwards .
Fitting the wiper blade
– Fit the new wiper blade into the mounting on the wiper
arm . You should hear it engage in the wiper arm.
– Fold the wiper arm back down onto the glass.
WARNING
•
To prevent smearing on the glas s, the wiper blades should be
cleaned regularly using a window cleaner solution. If the wiper
blades are very dirty (i nsects etc.), they should be cleaned using a
sponge or cloth – bad visibility can cause accidents.
•
For safety, the wiper blades shou ld be changed once or twice a
year.Caution
The windscreen wipers must be in the service position ⇒page 67
when replacing the blades! Otherwise the wiper motor or the paint-
work on the bonnet may be damaged.Rear-view mirrorsManual anti-dazzle adjustmentNormal setting

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.

Care of vehicle and cleaning245
Controls
Safety
Driving tips
General maintenance

Technical data
WARNING
•
Do not wash the vehicle with the ignition switched on – risk of
accident.
•
Do not clean the underside of th e car or inside the wheel arches
without protecting your hands and arms. You may cut yourself on
sharp metal parts.
•
Take care when washing the car during the winter: moisture
and ice on the brakes may affect braking efficiency – this could
cause an accident.Caution
•
Do not wash the vehicle in direct sunlight – otherwise the paint
can be damaged.
•
Do not use insect sponges or ab rasive household sponges, etc.
– they can damage the surfaces.
•
The headlights should only be washed with water – do not wipe
them with a dry cloth or sponge . It is best to use soapy water.
•
Never wash tyres with a jet that sprays the water out in a direct
stream. This could damage the tyres – even if the spray is kept at a
distance and only used for a very short time.For the sake of the environment
The car should only be washed in special wash bays. This prevents
oily water from getting into the pu blic drains. In some districts,
washing vehicles anywhere else may be prohibited.Waxing and polishingWaxing
Waxing protects the paintwork. It is time to apply a good coat of wax
when water no longer forms droplets and rolls off the clean paint-
work. Even if a
wax solution is used regularly in the car wash, it is advis-
able to protect the paint with a coat of wax at least twice a year.
In the summer, you will find it is much easier to remove dead insects
(which accumulate on the bumper an d the front of the bonnet) if the
car has been waxed recently.
Polishing
Polishing is only necessary if the paint has lost its shine, and the
gloss cannot be brought back by putting on wax.
The car must be waxed after polishing if the polish used does not
contain wax compounds to seal the paint.
Caution
Matt painted and plastic parts mu st not be treated with wax or
polish.Ornamental trim and mouldingsThe metal brightwork on the body is made of aluminium rather than
chrome (for environmental reasons).
Dirt or marks on the trim mouldings should be removed with an
acid-free cleaning agent (do not use a chrome cleaner). Body polish
is also unsuitable for use on trim mouldings. The intensive cleaning
fluids often used before the car goes into a car wash may contain
alkaline substances, which can cause dull or milky patches when
they dry out.
Audi dealers carry stocks of cleaning products which have been
tested for use on your vehicle and are not harmful to the
environment.
