o 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 cluste r indicates that the func-
tion is activated. You can now ta ke your foot off the brake pedal.
As soon as you drive off in the normal way, the parking brake will
automatically be released and the vehicle will start moving.
If the conditions for Audi hold assist change and the function is
switched off as a result, the parking brake will be applied automati-
cally to ensure that the vehicle is parked safely. The diode in the
button will go out when the Audi hold assist function is switched
off.
WARNING
The intelligent technology in Audi hold assist cannot defy the laws
of physics. Do not let the extra convenience provided by Audi hold
assist tempt you into taking a safety risk.•
Audi hold assist cannot keep the vehicle stationary in all condi-
tions on a gradient (e.g. if the road is slippery or icy).
•
Audi hold assist must be swit ched on again each time the
engine is started – Risk of accident!
•
Never get out of the vehicle wh en the engine is running and
Audi hold assist is switched on – Risk of accident!
•
Always ensure that the vehicle is stopped properly and safely
to avoid injury to yourself and others.Caution
Switch off the Audi hold assist function before driving the vehicle
into a car wash.
Note
•
Audi hold assist can be switched on only when the driver's door
is closed, the driver's seat belt is buckled and the engine is running.
•
Audi hold assist prevents auto matic vehicles from creeping
forwards when the brake pedal is released with the car in gear.
•
When the vehicle has been stationary for an extended period,
Audi hold assist will automatically apply the parking brake. In this
case, the green symbol
 in the instrument cluster display will
change to red

Driving
126The cruise control system allows you to drive at a constant speed of
30 km/h or higher.
A constant speed is maintained by adjusting the engine power or
braking the vehicle accordingly (while in cruise mode).
The cruise control system is set using the control lever ⇒page 125,
fig. 138. The indicator lamp lights up while the system is operating
⇒ fig. 139.
The cruise control system is automatically deactivated immediately
when you press the brake pedal.
On vehicles with a manual gearbox, the cruise control system will be
deactivated if the clutch is pressed for a long time.
WARNING
•
Always direct your full attention to the road, even when you are
using the cruise control system. It is always you who is respon-
sible for determining your speed and for keeping a safe distance
to the other vehicles on the road.
•
For safety reasons, the cruise control system must not be used
in city traffic, stop-go traffic, roads with a lot of bends or in diffi-
cult driving conditions (such as ice, fog, loose grit or gravel, heavy
rain, aquaplaning) - this could cause an accident!
•
When you take a turn-off, drive along a motorway exit lane or
pass through roadwork sections, please temporarily switch off the
cruise control system.
•
Please make sure you do not unintentionally rest your foot on
the accelerator - this will override the cruise control system which,
as a result, will not brake the vehicle.Caution
On vehicles with a manual gearbox: do not move the gear lever into
neutral without depressing the clutch when the cruise control
system is active. Otherwise the engine could rev up and be
damaged.
Note
•
On vehicles with a manual gearbox, the set speed cannot be
reached if the currently selected gear is too high or too low. Change
down to a lower gear when the engine no longer runs “smoothly” or
change up a gear to avoid overrevving the engine.
•
The brake lights come on when the system brakes the vehicle.

Automatic gearbox
130Automatic gearboxmultitronic
®
Applies to vehicles: with multitronic®IntroductionThe vehicle is equipped with an electronically controlled continu-
ously variable transmission (multitronic
®). Unlike conventional
automatics, the gear ratios are not shifted in fixed steps but contin-
uously variable. This gives smoother transmission and makes for
better fuel economy.
The gearbox selects the gear ratio and shifts up or down automati-
cally according to the gear change programmes stored in the
control unit ⇒page 133, “Dynamic gear control program (DCP)”.
The gearbox also has the tiptronic manual shift feature. This system
allows the driver to select gears manually if required ⇒ page 134.
Please note that on vehicles with a multitronic gearbox, torque is
transmitted via a multi- plate clutch, and not via a torque converter
as on conventional automatics. This means that the car will not
“creep” as much as conventional automatics when the engine is
idling if you stop temporarily with the selector lever in position D, S
or R.
Applies to vehicles: with multitronic®General notes on using multitronic
®
The transmission ratio is varied continuously.Driving away from a standstill
– Press and hold the brake pedal.
– Press and hold the interlock button (the button in the selector lever handle), move the selector lever to the
desired position, for instance D, and release the interlock
button.
– Wait for the gearbox to engage the gear (a slight move- ment can be felt).
– Release the brake and press the accelerator ⇒.
Stopping briefly
– Apply the foot brake to hold the vehicle when stationary (for instance at traffic lights).

Automatic gearbox
132Reverse 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 134 , 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 tran smits power 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 231, “Working on components in the
engine compartment”.
Applies to vehicles: with multitronic®Selector lever lock
The selector lever lock prevents gears from being
engaged inadvertently, so that the vehicle is not set in
motion unintentionally.The selector lever lock is released as follows:
– Switch on the ignition.

– Press the brake pedal and at the same time press in the
interlock button.Automatic selector lever lock
The selector lever is locked in the P and N positions when the igni-
tion is on. The brake pedal must be depressed before the lever can
be moved out of either of these positions. The following message
appears in the instrument display as a reminder for the driver when
the selector lever is in position P or N:
WHEN STATIONARY APPLY FOOTBRAKE WHILE SELECTING GEAR.
The selector lever lock only works if the vehicle is stationary or
driving at speeds up to 5 km/h. At higher speeds the selector lever
lock in the N position is disengaged automatically.
The selector lever lock is not engaged if the selector lever is moved
quickly through position N (e.g. when shifting from R to D). This
makes it possible, for instance, to “rock” the vehicle backwards and
forwards if it is stuck in snow or mud. The selector lever lock
engages automatically if the brake pedal is not depressed and the
lever is in position N for more than about a second.
Interlock button
The interlock button on the selector lever handle prevents the driver
from inadvertently engaging particul ar gears. Press the button in to
disengage the selector lever lock. Th e illustration shows the selector
lever positions in which the button has to be pressed, highlighted in
colour ⇒page 132, fig. 146.
Safety interlock for ignition key
The key can only be withdrawn with the ignition switched off and
the selector lever in position P. When the ignition key is removed,
the selector lever is locked in position P.
Applies to vehicles: with multitronic®Kick-down feature
The kick-down feature is designed to give maximum
acceleration.When the accelerator pedal is pressed right down past the point of
resistance at full throttle, the gearbox will select a lower gear,
depending on road speed and engine speed. While you keep the
accelerator depressed the engine speed is automatically controlled
to give your vehicle maximum acceleration.
WARNING
Please note that if the road surf ace is slippery or wet, the kick-
down feature could cause the driv ing wheels to spin, which could
result in skidding.Applies to vehicles: with multitronic®Dynamic gear control program (DCP)
The multitronic
® gearbox is controlled electronically.
The vehicle is equipped with an electronically controlled gearbox.
The gear ratios are selected automatically according to preset gear-
shift programmes.
When you drive at moderate speeds the gearbox will select the most
economical shift programme. It will then change up early and delay
the downshifts to give better fuel economy.
If you drive at higher speeds with heavy acceleration, if you open the
throttle quickly, or if you use the kick-down or the car's maximum
speed, the gearbox will automaticall y select the more “sporty” shift
programmes.
The gearbox is self-adapting, and continuously selects the most
suitable shift programme. At the same time, the driver can also
make the gearbox switch to a more "sporty" programme by pressing

Safe driving
164Correct sitting positionsCorrect sitting position for driver
The correct driving position is important for safe and
fatigue-free driving.For your own safety, and to reduce the risk of injury in the
event of an accident, we re commend the following driving
position.
– Adjust the steering wheel so there is a distance of at least 25 cm between the steering wheel and your breastbone
⇒fig. 173. – Move the driver's seat forwards or backwards so that you
can press the accelerator, brake and clutch pedals all the
way to the floor with your knees slightly bent ⇒.
– Make sure that you can comfortably reach the top of the steering wheel.
– Adjust the head restraint so that the top of the head restraint is level with the top of your head ⇒fig. 174.
– Adjust the backrest to an upright position so that your back remains in contact with the upholstery.
– Fasten your seat belt correctly ⇒page 170 .
– Keep both feet in the footwe ll so that you are in full
control of the vehicle at all times.
For detailed information on how to adjust the driver's seat, see
⇒ page 70, “Seats and storage”.
WARNING
•
A driver who is not sitting in the correct position or who is not
wearing a seat belt can be fatally injured if the airbag is triggered.
•
Adjust the driver's seat so there is a distance of at least 25 cm
between your breastbone and th e centre of the steering wheel
⇒ fig. 173.
•
While driving, always hold the steering wheel with both hands
on the outside of the rim at about the 9 o'clock and 3 o'clock posi-
tion. This reduces the risk of injury if the driver's airbag inflates.
•
Never hold the steering wheel at the 12 o'clock position, or
with your hands inside the rim or on the steering wheel hub. This
could result in serious injuries to the arms, hands and head if the
driver's airbag inflates.
•
To reduce any risk of injury to the driver during a sudden brake
application or in an accident, neve r drive with the backrest tilted

Switching off
The ESP should normally be left switched on at all times. If required,
you can press the ESP OFF button to switch off the traction control
system (ASR) or the electronic stabilisation program (ESP).
•
Switching off the traction control system (ASR):
Press the ESP
button briefly. The traction control system (ASR) can be switched off
in special driving conditions, e.g. if you are driving with snow chains
⇒ page 198 . The message ASR off will appear in the display.
•
Switching off the ESP/traction control system (ASR): Press the
ESP button for longer than 3 seconds. The ESP/ASR warning lamp
lights up when the system is switched off, see ⇒page 16 . The
message ESP switched off will appear in the display.
WARNING
•
The ESP is not able to overcome th e physical limits of adhesion.
Even with ESP, you sh ould always adjust your speed to suit the
conditions. Please bear this in mind, especially on wet or slippery
road surfaces. Do not let the extr a safety provided tempt you into
taking any risks when drivin g – this can cause accidents.
•
Please note that, when the ESP or ESP/traction control system
(ASR) is switched off, the driven wheels may start to spin, causing
the vehicle to lose grip, in part icular on slippery or wet roads -
danger of skidding!
Anti-lock brake system (ABS)
ABS prevents the wheels from locking up under braking.The anti-lock brake system (ABS) is an important part of the car's
active safety system. However, the ABS will not necessarily guar-
antee shorter stopping distances in all conditions. For instance, on
loose gravel or fresh snow on top of an icy surface (conditions which
anyway require extreme care and reduced speed), the stopping
distance with ABS may even be slightly longer. How the ABS works
The system runs an automatic self-check when the car reaches a
road speed of about 6 km/h. This may be accompanied by a noise
from the ABS pump.
If one of the wheels is turning too slowly in relation to the road
speed, and is close to locking up, the system will reduce the pres-
sure in the brake line to this wheel. The driver is made aware of this
control process by a
pulsating of the brake pedal and accompa-
nying noise. This is a deliberate warning to the driver that one or
more of the wheels is tending to lock up and the ABS control func-
tion has intervened. In this situation it is important to keep the brake
pedal fully depressed so the ABS can regulate the brake application
- do not “pump” the brake pedal.
WARNING
The grip provided by ABS is still su bject to the physical limits of
adhesion. Always bear this in mind, especially on wet or slippery
roads. If you notice that the AB S is working (to counteract locked
wheels under braking), you should reduce speed immediately to
suit the road and traffic conditio ns. Do not let the extra safety
provided tempt you into taking an y risks when driving – this can
cause accidents.
Note
If a malfunction should occur in the ABS, this is indicated by a
warning lamp ⇒page 18 .Brake assist system
The brake assist system helps the driver to achieve
optimum braking effect.The brake assist system helps to increase braking power and thus to
achieve a shorter stopping distance . If the driver presses the brake

Intelligent technology
198pedal very quickly, the brake assist system automatically boosts the
braking force to the maximum level, up to the point where the anti-
lock brake function (ABS) intervenes to stop the wheels from
locking. You should then keep the brake pedal pressed until the
vehicle has braked to the required speed. The brake assist system
switches itself off as soon as you release the brake pedal.
The brake assist system will not be operative if there is a malfunc-
tion 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 too close behind the vehicle in front of you. An increased
accident risk cannot be compensated even by the brake assist
system, so always be sure to maintain a safe speed.Traction control system (ASR)
The traction control system prevents the driven wheels
from spinning when the car is accelerating.General notes
The traction control system (ASR) is one of the functions incorpo-
rated in the electronic stabilisation program (ESP).
The traction control system (ASR) helps the car to start moving,
accelerate and climb a gradient in slippery conditions where this
may otherwise be difficult or even impossible.
How the system works
The ASR acts automatically i.e. without the driver's intervention.
With the aid of the ABS sensors ⇒page 197 , the ASR monitors the
speed of the driven wheels. If the wheels start to spin, the engine
power is reduced automatically to match the amount of grip avail-
able. The system works at all speeds. The ASR works in conjunction with the ABS. If a malfunction should
occur in the ABS, the ASR will also be out of action.
Switching on
The ESP is switched on automatically when the engine is started
and performs a self-test routine. As soon as this routine is complete,
the system switches back to normal operating mode. If the traction
control system (ASR) has been deactivated (for one of the reasons
noted below) you can switch it back on manually by pressing the
switch
⇒page 196, fig. 203. The message ESP/ASR on will appear
briefly in the display. If the traction control system (ASR) has been
deactivated, it will switch back on automatically at a speed of about
70 km/h on vehicles with front-wheel drive.
You can switch the traction control system (ASR) on again if neces-
sary by pressing the switch ⇒page 196, fig. 203.
Switching off
If required, the ASR can also be switched off manually by pressing
the switch briefly ⇒page 196, fig. 203 (for less than 3 seconds). The
ESP warning lamp lights up when the traction control system (ASR)
is switched off, see ⇒page 16 . The message ASR off will appear in
the display. For safety reasons, the system can only be switched off
at speeds below 50 km/h on vehicl es with front-wheel drive. The
ASR can be deactivated at any speed on vehicles with four-wheel
drive.
The traction control system should normally remain switched on at
all times. It should only be switched off manually in particular
circumstances where a certain amount of wheel slip may be desir-
able. For example:
•
when driving with snow chains
•
when driving in deep snow or on loose surfaces
•
when rocking the car backwards and forwards to free it.
The ASR should be switched on again afterwards as soon as
possible.
