& WARNING
Improper use of steering wheel adjustment and improper seating
position can cause serious personal injury .
• Adjust the steer ing wheel column only when the vehicle is not
moving to prevent loss of vehicle control.
• Adjust the dri ver's seat or steering wheel so that there is a
minimum of 10 inches (25 cm) between your chest and the
steering wheel=>
page 178, fig. 178 . If you cannot maintain this
minimum distance , the airbag system cannot protect you prop­
erly .
• If physical limitations prevent you from sitting 10 inches (25
cm) or more from the steering wheel, check with your authorized
Audi dealer to see if adaptive equipment is available.
• If the steering wheel is al igned with your face, the supple­
mental driver 's airbag cannot provide as much protection in an
accident . Always make sure that the steering wheel is aligned with
your chest.
• Always hold the steering wheel with your hands at the 9 o 'clock
and 3 o'clock positions to reduce the risk of personal injury if the
driver's airbag deploys .
• Never hold the steering wheel at the 12 o'clock po sition or with
your hands inside the steering wheel
rim or on the steer ing wheel
hub. Holding the stee ring wheel the wrong way can cause serious
injur ies to the hands, arms and head if the driver's airbag
deploys. •

more detail. If the driver message Parking brake! appears, there is an
operat ing malfunction in the parking brake which you should have
repaired immediately by an authorized Audi dealer or other qualified
workshop ~
page 28.
[I] Tips
• You can apply the parking brake at any time -even with the igni­
tion turned off. The ig nition must be turned on in order to release the
parking brake.
• Occasional noises when the parking brake is applied and released
are normal and are not a cause for concern.
• When the vehicle is parked, the parking brake goes through a self­
test cycle at regular intervals . Any associated noises are normal. •
Parking
Various rules apply to prevent the parked vehicle from
rolling away accidentally.
Parking
-Stop the vehicle with the foot brake.
- Pull the switch to apply t he parking brake.
- Move the selector lever to P.
- Turn the engine off::::>&.
In addition on inclines and grades
-Turn the steering wheel so that your vehicle will ro ll
against the curb in case it should start to move.
_& WARNING
• When you leave your vehicle -even if only briefly· always
remove the ignition key. This applies particularly when children

ment Safety first

remain in the vehicle. Otherwise the children could start the
engine, release the parking brake or operate electrical equipment
(e.g. power windows). There is the risk of an accident.
• When the vehicle is locked, no one -particularly not children
should remain in the vehicle. Locked doors make it more difficult
for emergency workers to get into the vehicle -putting lives at
risk. •
Starting from rest
The starting assist function ensures that the parking
brake is released automatically upon starting.
Stopping and applying parking brake
-Pull the switch to apply the parking brake.
Starting and automatically releasing the
parking brake
- When you start to drive as usual, the parking brake is auto -
matically released and your vehicle begins to move.
Whe n stopping at a tra ffic signal or stopping in city traffic on ve hicles
with an automatic transmission, the parking brake can be applied.
Th e vehicle does not have to be held with the footbrake. The parking
brake eliminates the tendency to creep with a drive range engaged.
As soon as you drive off as usual, the parking brake is released auto­
matically and the vehicle starts to move.
Starting on slopes
When starting on inclines, the starting assist prevents the vehicle
from unintentionally rolling back. The braking force of the parking
brake is not released until sufficient driving force has been built up at
the whee ls. ..,
