A WARNING ,~
- If the 1111 (USA models)/ . (Canada mod­
els) brake system indicator light turns on to­
gether with the ABS and ESC indicator
lights, the ABS/ESC regulating function may
have failed. Functions that stabilize the ve­
hicle are no longer available. This could
cause the vehicle to swerve and increase the
risk of sliding. Drive carefully to the nearest
authorized Audi dealer or other qualified
workshop and have the malfunction correct­
ed.
- If the brake warning/indicator light does
not go out after a few seconds and the park­
ing brake is released, or lights up while you
are driving, the fluid level in the brake fluid reservoir is too low. If you believe that it is
safe to do so, proceed immediately at low
speed to the nearest authorized Audi dealer
or qualified repair facility and have the
brake system inspected.
- Always keep in mind that after several brake
applications, you will need greater pressure
on the brake pedal to stop your vehicle. Do
not rely on strained brakes to respond with
maximum stopping power in critical situa­
tions. You must allow for increased braking
distances. The extra distance used up by
fading brakes could lead to an accident.

Smart Technolog y
Operating c ondit ion s and drivin g hab it s
The brakes on today 's automobi les are st ill sub­
ject to wear, depending largely on operating con­ ditions and driving habits¢.&. . On vehicles that
are either driven mostly in stop-and-go city traf­
f ic or are driven hard, the brake pads should be
checked by your authori zed Audi dealer more of­
ten than specified in the
Wa rra nty & Mainte­
n an ce boo kle t .
Fa ilure to have your brake pads
inspected can result in reduced brake perform­
ance.
On steep slopes, you should use the brak ing ef­
fect of the eng ine . Th is way, you prevent unnec ­
essary wear on the brake system. If you must use
your brakes, do not ho ld the brakes down contin­
uously. Pump the brakes at inte rva ls.
Operat ing no ise
Noises may occur when braking depending on the
speed, brak ing force and outside conditions such
as temperature and humid ity .
Effect of w ate r an d r oad sal t
In certain situations, for example after driving
through water, in heavy rain, after overn ight con­
densat ion or after washing your car, the braking
effect can be reduced by mo isture or ice on the
brake rotors and brake pads . The brakes must be
d ried first with a few carefu l brake applications.
At h igher speeds and with the w indshield wipers
turned on, the brake pads press against the brake rotors for a short amount of t ime . This occurs at
regular intervals without the d river noticing and
p rov ides for better brake response t ime unde r
wet conditions .
The effectiveness of the brakes can be reduced
when the vehicle is dr iven on a salt-covered road
a nd the brakes are not used . L ikew ise, you clean
off accumulated sa lt coating from brake discs
and pads with a few cautious applications of the brake ¢.&. .
Corros ion
There may be a tendency for dirt to bui ld up on
the brake pads and corros ion to fo rm on the discs
if the car is not driven regularly or on ly for short
trips with litt le use of the brakes.
194
If the brakes are not used frequently, or if corro­
sion has formed on the discs, it is advisable to clean off the pads and d iscs by braking firmly a
few times from a moderate ly high speed¢.&. .
Fault s in the brak e system
If you shou ld notice a sudden increase in bra ke
pedal travel, then one of the two brake circuits
may have failed
¢ .&. .
Lo w b rake fluid l evel
Malfunctions can occur in the brake system if the
brake flu id leve l is too low. The brake fl uid level is
monitored electronica lly.
Brake boos ter
The brake booster increases the pressure that you
generate w ith the brake pedal. It on ly operates
whi le the engine is runn ing o r with the ig nit ion
switched on (hybrid drive*)
¢ ,& .
Brake lining we ar status
Brake lining wear may be checked by visual in ­
spection of the condition of the brake pads
through the open ings in the wheel. If necessary ,
the wheel may be removed for this inspec tion
¢ page 260, Replacing wheels .
& WARNING -
- New brake pads don't have the best stop­
ping power and m ust be "broken-in" during
the initial 250 miles (400 km) . You can com­
pensate for this by pressing the brake pedal
more f irm ly. This also applies later when
new pads are installed.
- You should perform braking maneuvers for
the purpose of cleaning the brake system
only if road conditions permit. Other road
users must not be put at r isk -you may
cause an accident!
- Before descend ing a steep grade, reduce
speed and sh ift transmission into a lower
gea r or lower dr iving range. Do not ride the
bra kes or ho ld the peda l down too long or
too often . This could cause the bra kes to get
hot and diminish braking efficiency.
- Do not "ride the brakes" by rest ing your foot
on the pedal when you do not intend to

conditions and off-road
General information
The opera tion of the E lectronic Stabilization Con­
trol (ESC) is expanded for operation away from paved roads. In situat ions where s lip or a differ­
ential locking function is required, the offroad mode can be activated
<=> page 191. Your Aud i al­
so has permanent a ll-wheel drive in addition .
However, your Audi is not a pure offroad veh icle.
It was not bu ilt for driving under extreme condi­
tions, e.g. for trips that are in the nature of an ex­
pedit io n.
Dri ve o nly on roads and offro ad sections which
match the des ign of you r vehicle and your abil i­
ties as a dr iver. Neve r take r isks!
B efo re driving offroad
- Check the eng ine oil level, tire p ressure, cool­
ant leve l, and the fluid level i n the windshield
washer reservo ir.
- Stow luggage items and other objects in the
lu ggage compartment, and sec ure them
against slid ing aro und.
After dri ving off road
- After trips offroad, remove any twigs and othe r
f oreign objects from the grill, the unde rbody
and the wheels . Pay special attention to foreign
objects (stones) which have become lodged in
the tire tread.
- Clean the body and the vehicle unders ide, and
inspect the vehicle for poss ible damage.
- Clean dirty windows, headlamp lenses, rear
lights, and license p lates.
- Perform a brake check (particularly after t ravel ­
li ng through water).
A WARNING
- Drive especia lly attentive ly and plan ahead
in diffic ult road cond itions and w hen
off­
road. Excessive speed or incorrect mane u­
vers can cause in ju ries and damage to the
vehicle.
202
- Always adapt your speed and driving sty le to
road, off road, traffic, and weather cond i­
tions. Dr ive espec ially slowly offroad w hen
your view is restricted.
- Please be aware that in offroad mode, par­
ticularly on a smooth and slippery road, the
wheels may have an increased tendency to
spin and the vehicle may break away -dan­
ge r of skidding!
- Stability is limited in the offroad mode .
