& WARNING
Improper use of steering wheel adjustment and improper seating
position can cause serious personal injury.
• Adjust the steering wheel column only when the vehicle is not
moving to prevent loss of vehicle control .
• Adjust the driver's seat or steering wheel so that there is a
minimum of 10 inches (25 cm ) between your chest and the
steering wheel~
page 194 , fig. 188 . If you cannot maintain this
minimum distance , the airbag system cannot protect you prop ­
erly .
• If physical limitations prevent you from sitting 1 O inches (25
cml or more from the steering wheel , check with your authorized
Audi dealer to see if adaptive equipment is available.
• If the steering wheel is aligned 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 position or with
your hands inside the steering wheel rim or on the steer ing wheel
hub . Holding the steering wheel the wrong way can cause serious
injuries to the hands, arms and head if the driver's airbag
deploys. •

[ i] Tips
• You can apply the parking brake at any time - even with the igni­
tion turned off. The ignition 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 .
• The parking brake goes through a self -test cycle at regular inter ­
vals - when the vehicle is parked . Any associated noises are
normal. •
Parking
To prevent a parked vehicle from rolling away, there are a
few things you should do.
When you park your vehicle, do the following
- Stop the vehicle using the brake pedal.
- Pull the switch to apply the electromechanical parking
brake.
- Move the selector lever into the
P position ~& .
- Switch off the engine and remove the ignition key from
the ignition lock.
When you park your vehicle on hills, do the
following - Stop the vehicle using the brake pedal.
- Pull the switch to apply the electromechanical parking
brake.
- If you are parking headed downhill, turn the front wheels
toward the curb. - If you are
parking headed uphill, turn the front wheels
awayfrom the curb.
- Move the selector lever into the P position .
- Switch off the engine and remove the ignition key from
the ignition lock.
& WARNING
This is how you can reduce the risk of injury when leaving your
vehicle.
• Never park the vehicle where it can come in contact with dry
grass, spilled fuel or any other flammable materials.
• When parking on hills, always turn the wheels so that the front
wheels will first roll into the curb, if the vehicle should start to roll.
• Never allow anyone -especially small children -to remain in the
vehicle when it is locked. Locked doors make it more difficult for
rescuers to access the passenger compartment in the event of an
emergency. Danger to life!
• Never leave children unsupervised in the vehicle. Children
could release the parking brake or move the gearshift lever out of
gear. The vehicle could start to roll away and cause an accident.
• No matter what the season is, the temperature in a parked
vehicle can reach dangerous levels.
0 Note
• Please exercise care when you park your vehicle in parking areas
with parking barriers or curbs. Parking barriers and curbs vary in height and could damage your bumper and related components as
the front of your vehicle moves over a barrier or curb that is too
high, as you park or as you back out of a parking spot. In order to be
sure that no such damage can occur, you may wish to stop short of
having the front tires of your car touch the parking barrier or curb . ..,_
