Other road users must not be put at risk -
you may cause an acc ident!
- Before descending a steep grade, reduce
speed and shift transmission
into a lower
gear or lower driving position . Do not
ride the brakes or ho ld the pedal down
too long or too often . This cou ld cause
the brakes to get hot and d iminish brak-
ing efficiency .
- Do not "ride the brakes" by resting your
foot on the pedal when you do not intend
to brake . This may cause the brakes to
overheat, premature wea r a nd increased
stopp ing distance.
- Under certain climat ic and operating
condit ions such as passing through wa-
ter, driving in heavy rain or after wash ing
the vehicle, the effectiveness of the
brakes can be reduced . In winter, ice can
accumulate on the brake pads, linings,
discs and drums. Cautiously apply brakes
for a test . Brakes will dry and ice coat-
ings w ill be cleaned off after a few cau -
t ious brake applications .
- Driving for an extended period of time on
salt-covered roads w ithout us ing your
brakes can also affect braking efficiency .
Clean off accumulated salt coating from
brake discs and pads with a few cautious
brake applicat ions.
- If you damage the front spoiler, or if you
inst all a different spoiler, be su re the air
flow to the front brakes is not obstruct -
ed. Otherwise the brake system could
overheat red ucing the effectiveness of
the ent ire brake system.
- Failure of one brake circuit will impair
braking capab ility, resulting in increased
stopp ing distance. Avoid driving the vehi-
cle and have it towed to the nearest au-
thorized Aud i dealer or qualified work-
shop .
- Never let the vehicle roll to a stop with
the engine shut off .
- If the brake booster is not working, for
example when tow ing your vehicle, or
because the brake booste r has somehow
been damaged, the brake pedal must be
pressed considerably harder to make up
for the lack of booster assistance .
Power
steering
When the engine is running, power steering
makes it easier for the driver t o s teer.
Power steering helps the driver steer the vehi-
cle with litt le physica l effort.
If the engine is not running, the power steer-
ing system is also not working . In this case ,
you will find it extremely d ifficu lt to turn the
steering wheel.
If you turn the steering
fully
to the left or
rig ht when the vehicle is stationary, you p lace
a very heavy load on the power steering sys-
tem. Turning the steering wheel fully to the
left or right will cause noise in the system. It
also reduces engine idle speed.

Note
Do not hold the steering t urned fu lly to
the left or right for more than 10 seconds
when the engine is running . There is a risk
of damage to the power steering system .

Tips
- In the event of a power steering system
failure, or if the engine is not running
(while being towed), you will still be ab le
to steer the vehicle. However, you will re-
quire more effort to do so .
- If the powe r stee ring system has a leak
or is defect ive, you should immediately
contact a qualified wor kshop .
- The power steer ing system req uires a
special hydraulic fl uid. The power steer-
ing fluid reservoir is located in t he en-
gine comp ar tment. The co rrect hydrauli c
fluid level is important for proper opera-
tion of the power steering system. The
power steering fluid level is checked ac-
cording to the Audi maintenance service
schedule.
