2008 AUDI A4 ignition

Driving 122a fault in the parking brake. Have the fault repaired by a qualified
workshop without delay ⇒page 32.
Note
•
The parking brake can be applied at any time - even when the
ignition is switched off. However, the ignition must be switched on
before the parking brake can be released.
•
Any slight noise which may be heard when the parking brake is
applied or released is quite normal and no cause for concern.
•
The parking brake runs an automatic test cycle at regular inter-
vals when the vehicle is parked. This may also cause a slight noise,
which is normal.
Parking
Please note the following points to ensure there is no risk
of the car rolling away accidentally after it is parked.Parking t he c ar
– Use the foot brake to stop the vehicle.
– Pull the switch to apply the parking brake.
– Automatic gearbox: Move the selector lever to P.
– Switch off the engine ⇒.
– Manual gearbox: Engage the first gear.
When parking on slopes
– Turn the steering wheel so that the vehicle would roll into
the kerb if it did start to move accidentally.
WARNING
•
Always take the key with you when leaving the vehicle – even
if you only intend to be gone for a short time. This is especially
important if children are left in the car. They might otherwise be
able to start the engine, release the parking brake or use power-
operated equipment such as the electric windows - this could lead
to injuries.
•
Do not leave anyone (especially children) in the vehicle when it
is locked. Locked doors could delay assistance in an emergency,
potentially putting lives at risk.
Driving away from a standstill
The parking brake auto release function releases the
parking brake automatically when you wish to start
moving.Applying the parking brake when stopping
– Pull the switch to apply the parking brake.
Releasing the parking brake when driving away
– Drive off in the normal way: the parking brake will be
released automatically and the vehicle will start moving.On vehicles with automatic gearbox, you can apply the parking
brake when stopping at traffic lights, etc. Then you do not have to
hold the car with the footbrake, as the parking brake will stop it
creeping forward while a gear is engaged in the automatic transmis-
sion. When you drive off in the normal way, the parking brake will be
released automatically and the vehicle will start moving.
Driving away on a slope
When driving away on a gradient, the parking brake auto release
function prevents the vehicle from rolling back unintentionally. The

Self-help
Technical data
•
Adaptive cruise control will not react when approaching a
stationary obstacle, e.g. the end of a traffic jam or a broken-down
vehicle, or if a vehicle should come towards you in the same lane.
•
Please make sure you do not unintentionally rest your foot on
the accelerator - this will override the adaptive cruise control
system which, as a result, will not automatically brake the vehicle.Note
•
For safety reasons, the speed setting will be deleted when the
ignition is switched off.
•
Switching on the adaptive cruise control automatically activates
the Electronic Stabilisation Program (ESP) and the traction control
system (ASR). These two systems cannot be deactivated while the
adaptive cruise control is switched on.
•
Damage caused by impacts (e.g. if the vehicle is damaged when
parking) can affect the radar sensor settings. This can cause the
system to malfunction or switch off completely.
•
The radar sensor is heated. However, in winter conditions, you
should make sure that the radar sensor is free of ice and snow
before you set off. If necessary, carefully clean the cover of the radar
sensor and the surrounding area ⇒page 128, fig. 136.
•
To make sure that the radar sensor is fully operative, do not
attach any objects (e.g. stickers, add-on parts or other accessories)
to the area surrounding the radar sensor. Do not paint the area
surrounding the radar sensor.
Applies to vehicles: with adaptive cruise control and manual gearboxVehicles with manual gearbox
The driver of a vehicle with a manual gearbox of course
has to change gears as appropriate, even when the adap-
tive cruise control is activated.The adaptive cruise control is available from the second to the sixth
gear (when driven in normal engine speed range).
When the adaptive cruise control is activated, the driver must press
the clutch pedal as normal in order to change gear. When changing
gear or pressing the clutch pedal (for up to 20 seconds), the adap-
tive cruise control will remain activated.
When changing gear, the driver does not have to accelerate after
engaging a gear as the engine torque will be coordinated by the
adaptive cruise control.
The following situations may lead to an automatic deactivation of
the adaptive cruise control:•
pressing the clutch pedal too long (longer than approx.
20 seconds)
•
incorrect changing of gears and/or use of the clutch pedalNote
•
The adaptive cruise control cannot be activated while changing
gears.

adaptive cruise control (ACC) 140Setting the driving program
In the Driving program menu you can select either dynamic,
standard or comfort according to your personal preferences.
Note
•
We recommend you to leave the warning tone switched on. Even
when the warning tone is switched off, not every warning tone will
be deactivated.
•
When you pass the key on to somebody else please remember to
make the other driver aware of the ACC settings.
•
We recommend a minimum distance setting of DISTANCE 3
(factory default setting).
•
When the ignition is switched off, the distance setting reverts to
the factory default DISTANCE 3. A qualified workshop can cancel
this function. In this case a default distance setting defined on the
sound system or MMI* is applied each time the engine is started.
System limitationsApplies to vehicles: with adaptive cruise controlGeneral notes
The following situations could impair the function of the
radar sensor.The adaptive cruise control is subject to given physical limits and
also has certain limits determined by the system itself. Under
certain circumstances the driver may feel that the ACC system is
responding unexpectedly or belatedly. For this reason, please
always give your full attention to road traffic and if necessary take
action yourself:•
When driving through bends ⇒page 140.
•
When vehicles in front are not in line with your vehicle
⇒page 141.
•
When other vehicles change lanes ⇒page 141.
•
When other vehicles are not clearly discernible ⇒page 141
•
When vehicles are stationary ⇒page 142.
WARNING
The radar sensor's "field of vision" can be impaired by rain, snow
or a lot of water on the road. This results in vehicles in front not
being properly recognised or, in some circumstances, not being
detected at all. If necessary, take action yourself!Applies to vehicles: with adaptive cruise controlWhen driving through bends

Note•
You can select the sport program for gear changes on vehicles
with an automatic gearbox* by activating the DYNAMIC mode. There
is no S position on the selector lever.
•
You may hear a noise on vehicles with dynamic steering* when
you start or stop the engine. This is no cause for concern.
Applies to vehicles: with Audi drive selectSelecting the driving mode
You can choose between COMFORT, AUTO, DYNAMIC and
INDIVIDUAL*.
The control is next to the selector gate ⇒fig. 174 on vehi-
cles with sound system, or in the centre console ⇒fig. 175
on vehicles with MMI*.
– Switch on the ignition.
– Press the left or right arrow button until the desired
mode lights up in red.You can change the driving mode while the vehicle is stationary or
moving. If traffic conditions permit, take your foot off the acceler-
ator briefly after you change the mode so that the new mode is also
activated for the engine.
COMFORT
The COMFORT mode alters the vehicle set-up for a more comfort-
able ride. The response of the engine and automatic gearbox* to
accelerator pedal movements is balanced. The steering is light and
indirect* and the suspension control* is set to soft. This setting is
suitable for driving long distances on motorways for example.
AUTO
The overall impression in AUTO mode is of a comfortable but
dynamic ride. This setting is suitable for everyday use.
DYNAMIC
DYNAMIC gives the vehicle a tighter set-up. The engine reacts spon-
taneously to accelerator pedal movements and the steering is
dynamic and direct*. The suspension control* is stiffer and the
automatic gearbox* changes gear at higher engine speeds. This
setting is ideal for performance driving.
INDIVIDUAL*
You can configure this mode on the MMI according to your personal
preferences.

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 automatically 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 power even at idling speed, and the
vehicle tends to “creep”. The throttle must on no account be
opened inadvertently (for instance by hand from the engine
compartment) when a gear is engaged with the vehicle stationary.
The vehicle could otherwise start moving immediately (in some
cases even if the parking brake is engaged) and possibly cause an
accident.
•
To avoid accidents, apply the parking brake and put the
selector lever in position P before 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.

Applies to vehicles: with multitronic® or tiptronicSelector 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 particular gears. Press the button in to
disengage the selector lever lock. The illustration shows the selector
lever positions in which the button has to be pressed, highlighted in
colour ⇒fig. 179.
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® or tiptronicKick-down feature
The kick-down feature is designed to give maximum
acceleration.Applies to vehicles with multitronic
® gearbox
When the accelerator pedal is pressed right down past the point of
resistance at full throttle, the gearbox will select a lower gear ratio,
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.
Applies to vehicles with tiptronic gearbox
When the accelerator pedal is pressed right down past the point of
resistance at full throttle, the gearbox will shift down to a lower
gear, depending on road speed and engine speed. The upshift to the
next higher gear is delayed until the engine reaches maximum rpm.
