adaptive cruise control (ACC) 142Applies to vehicles: with adaptive cruise controlStationary vehiclesIf a vehicle detected by the ACC system turns off or changes lane
and another stationary vehicle is located in front of that vehicle, the
ACC system will not react to the stationary vehicle ⇒fig. 154 and
⇒fig. 155.
Audi braking guardApplies to vehicles: with adaptive cruise controlDescription
Audi braking guard warns you in case of an impending
collision with a vehicle in front.Audi braking guard is active at speeds above approximately 30 km/h
and operates within the system limitations ⇒page 140 even when
the adaptive cruise control is deactivated.
The radar sensor is fitted at the front of the vehicle ⇒page 130,
fig. 137. The system requires reflecting surfaces in order to be able
to measure the distance. If the ACC is unable to measure the
distance it will not respond.
Once the system has measured the distance, it can assess a
dangerous situation where a vehicle in front brakes suddenly or you
are driving fast and approach a vehicle travelling at a much slower
speed. The system warns you as soon as it anticipates that a poten-
tial collision with the vehicle in front can only be avoided by hard
braking or by taking evasive action.
The system has a preset response time so that it can warn you in
time. In certain situations, the system response time will be reduced
dynamically, e.g. when you are accelerating onto a motorway.
Braking, lateral acceleration and steering angle are other factors

Audi lane assist 146Indicator lamp in instrument cluster Active: The green indicator lamp confirms that the system is fully
functional. You will be warned if you are about to cross the lane
markings detected by the system. Inactive: The yellow warning lamp indicates that the system is
switched on. However, you will not be warned if you cross the lane
markings. This can have the following causes:•
There is only one or no lane marking.
•
The system cannot detect the lane markings (e.g. due to snow,
dirt, wet conditions or adverse light).
•
There are more than two lane markings in the lane you are
driving in (e.g. in roadwork sections).
•
The vehicle's speed is below 65 km/h, the speed at which the lane
assist system is activated.
•
The lane is narrower than 2.5 m or wider than 5 m.
•
The bend is too tight.Note
•
Make sure that the camera window ⇒page 145, fig. 159 is not
covered with stickers or similar objects.
•
Always keep the camera window clean. Usually it should suffice
to operate the windscreen wipers.
Applies to vehicles: with lane assist and on-board computerInstrument cluster displayYou can call up the display for the lane assist by repeatedly pressing
the button on the windscreen wiper lever. For more details
refer to ⇒page 27.
When the lane assist is switched on, two lines indicate the lane
demarcations on the left and right of your vehicle.
Version : Monochrome display•
Solid red lines: The lane assist is switched on and ready to warn.
•
One red line flashing (left or right): The lane assist warns you
before you cross the lane demarcation ⇒fig. 160, A

Automatic gearbox 166
WARNING
Please note that if the road surface is slippery or wet, the kick-
down feature could cause the driving wheels to spin, which could
result in skidding.Applies to vehicles: with multitronic® or tiptronicDynamic gear control program (DCP)
The automatic 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 automatically 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
the accelerator quickly. Depending on road speed, this makes the
gearbox shift down early into a lower gear ratio for more rapid accel-
eration (for instance to pass another vehicle), without having to
press the accelerator all the way down into the kick-down position.
After the gearbox has shifted back up it returns to the original
programme, depending on your style of driving.
Vehicles with multitronic® gearbox: The gearbox continuously
adapts the gear ratios on uphill gradients. If the brake pedal is
pressed on a downhill gradient the gearbox automatically shifts to
a lower gear ratio. This increases the engine braking effect.Vehicles with tiptronic gearbox: The gearbox adapts the gearshifts
for uphill and downhill gradients. This prevents the gearbox from
shifting up and down unnecessarily on uphill gradients.
Applies to vehicles: with multitronic® or tiptronicManual gear selection (tiptronic mode)
With the manual shift programme (tiptronic) the driver
can manually select pre-programmed gears.Switching over to the manual programme
– From position D, push the selector lever to the right. As
soon as the automatic gearbox has changed over to this
programme, the display will show the selected gear.

Changing brake fluid
When required, the brake fluid should be changed by a
competent mechanic with the proper equipment.Brake fluid gradually absorbs moisture from the atmosphere. If the
water content in the brake fluid is too high, this may cause corrosion
in the brake system over time. In addition, the boiling point of the
brake fluid will be considerably reduced. This could adversely affect
the braking ability in certain circumstances.
For this reason the brake fluid must be changed periodically.
Your vehicle's Service Schedule will tell you when the brake fluid has
to be changed.
It is advisable to have the brake fluid changed as part of a regular
Inspection Service at your Audi workshop. They are familiar with the
procedure and have the necessary special tools and spare parts as
well as the proper facilities for disposing of the old fluid.
Use only the genuine brake fluid specified by the factory Qualified
workshops know that the brake fluid “DOT 4” is approved by Audi.
The brake fluid must be fresh and unused.
WARNING
•
Brake fluid is poisonous; store it in the sealed original container
in a safe place out of reach of children.
•
Heavy use of the brakes may cause a vapour lock if the brake
fluid is left in the system for too long. This would seriously affect
the efficiency of the brakes and the safety of the car – risk of acci-
dent.Caution
Please note that brake fluid will attack the paintwork on contact.
For the sake of the environment
If the fluid has to be drained out of the brake system, use an appro-
priate container to catch the used brake fluid and dispose of it in the
proper manner.BatteryGeneral notes
All work on batteries requires specialist knowledge.The battery is virtually maintenance-free. It is checked as part of the
Inspection Service.
We recommend that you replace a battery once it is older than 5
years.
When an airbag is triggered, the battery will, under certain circum-
stances, be disconnected from the on-board power supply for
safety reasons ⇒ in “General notes on airbag system” on
page 201.
Disconnecting the battery
If the battery is disconnected, some of the vehicle's functions will
become inoperative (e.g. electric windows). These functions will
require resetting after the battery is reconnected. For this reason,
the battery should only be disconnected from the vehicle's electrical
system when absolutely necessary.
If the vehicle is not used for long periods
If you do not drive your vehicle for a period of several days or weeks,
the power management will gradually shut off the on-board
systems one by one, or reduce the amount of current they are using.
This limits the amount of power consumed and helps to ensure reli-
able starting even after a long period ⇒page 226.
