in. WARNING
• You should perform braking maneuvers for the purpose of
cleaning the brake system only if road condition s permit. Other
road u sers must not b e put at r isk - you may cau se an ac cident!
• Before d esc ending a steep gr ade , redu ce speed and shift t ran s
mission into a lower gear or lower driving range. Do not ride the
brakes or hold the pedal down too long or too often . This could
c ause the brake s to get hot and diminish braking efficiency.
• Do not "ride the brakes " by re sting your foot on the pedal when
you do not intend to brake. Thi s may caus e the brakes to overheat ,
premature wear and increa sed stopping di stance.
• Under certain climatic and operating conditions such as
pas sing through water, driving in heavy rain or after washing the
vehicle, the effectiveness of the brake s can be reduced . In winter,
ice can accumulate on the brake pads , linings , disc s and drums .
Carefully apply brakes for a test. Brake s will dry and ice coatings
will be cleaned off after a few careful brake applications.
• Driving for an extended period of time on salt -cov ered roads
without using your brakes can al so affect braking efficiency. Clean
off accumulated salt coating from brake d iscs and pads with a few
careful brake applications.
• If you damage the front spoiler , or if you install a different
s poiler , be sure the air flow to the front brakes is not obstructed.
Otherwise the brake system could overheat reducing the effective
ness of the entire brake system.
• Failure of one brake circuit will impair the braking capability
resulting in an increased stopping distance. Avoid driving the
vehicle and have it towed to the nearest authorized Audi dealer or
qualified wo rkshop. •
Brake booster
The brake booster adds e xtra brakin g pow er .
The brake booster wor ks with vacuum pressure which is created on ly
w hen the en gine is ru nning =>& .
in. WARNING
• Never let the vehicle roll to a stop with the engine shut off .
• If the brake booster i s not working , for example when towing
your vehicle , or because the brake booster has somehow been
damaged , the b rake pedal must be p ressed considerably harder to
make up for the lack of booster assistan ce.
Functioning of Anti-Lock Brake System
(ABS)
AB S prevents the wheels from locking up under br aking.
T he ABS co ntribu tes effectively to vehicle co ntrol s ince it prevents t he
w hee ls from
locking when the b rakes are a pplied. This means t hat t he
veh icle rema ins steerable and is less likely to s kid .
W ith ABS you do not need to
pump the brake. Just hold the brake
pedal down .
However, do not expect the ABS to shorten braking distance u nder
all
circums tances. When driving on grave l or on newly fa llen snow on top
of icy su rfaces, braking dis tance may be even longer, therefore, under
these c irc umstances, it is especially important that you dr ive slowly
and w it h great care .
How the ABS system works
An automatic check is made when a speed of about 12 mph (20 km/h)
is reached . When this happens, a p umping noise can be hea rd. ._
_________________________________________ I_ n_ t_ e_ ll_,igent technology ,__E~-
If an individual wheel begins to rotate too slowly in relation to vehicle
speed and tends to lock, the ABS automatically reduces brake pres
sure to prevent that wheel from locking .
Thi s automatic adjustment process wi ll cause a
slight vibration of
the brake pedal and some noises to alert you that vehicle speed must
be adapted to existing road and traffic conditions.
_& WARNING
Although the ABS is very effective, always remember that braking
capability is limited by tire traction. Always adjust your driving
speed according to the road and traffic conditions. Do not let the
extra safety afforded by the ABS tempt you into taking extra risks.
The ABS cannot overcome the laws of physics .
(I) Tips
• If ABS is not funct ioning properly, a warning light will come on .
See ~
page 19.
• If a fault occurs in the ABS, the EDL is also not functioning. This is
ind icat ed by the ABS warning light. •
Brake assistant
The brake assistant is designed to achieve the optimum
braking effect.
The brake assistant helps to increase the effective braking power and
thus to achieve a shorter stopping distance.
If the driver presses the
brake peda l very qu ickly , the brake assistant automatically boosts the
braking force to the maximum level, up to the point where the anti
lock brake function (ABS) intervenes to stop the whee ls from locking.
You should then keep the brake pedal pressed until the vehicle has
braked to the required speed. The brake assistant switches itself off
as soon as you release the brake pedal.
Controls and equip ment Safety first Vehicle operation
Automatic full braking
assist
This function allows full braking in spite of high brake pedal forces
(e .g . when the brakes are severely stressed because the veh icle is fully
loaded). The driver notices this function through a reduction of pedal
force and increased pedal travel. When the brake pedal is released,
full braking assist switches off again automatically.
If there is an ABS failure, the brak e assistant and automatic full
braking assist are not available.
Th e brake assistant will not be operative if there is a ma lfunction in
the ABS .
_& WARNING
Please remember that the accident risk always increases if you
drive too fast, especially in corners or on a slippery road, or if you
follow the vehicle ahead of you too closely. Increased risk of an
accident cannot be compensated for even by the brake assistant ,
so always maintain a safe speed.•
Servotronic® -advanced power
steering system
The power steering systems uses the power of the
running engine to allow precise steering with little effort.
The advanced Servotronic ® power steering system senses the road
speed and electronically adjusts power assistance to provide
comfortable and safe steering response exactly matched to the
vehicle speed .
Power steering will not work if the engine is off. As a result , the
steering wheel will be hard to turn .
Th e power steering fluid level is checked during the scheduled main
tenance services.

Note
If t he re is an elect ro n ic malfunc tion, servotroni c will still funct io n
like a conventional power steering system, provid ing a constant
steer ing suppo rt force tha t is no longer proportiona te to the vehi cle
speed. This is most noticeable when t urning the steer ing wheel at low
speeds (for ex ample when p arki ng) , - m ore effo rt will be req uire d
than usua l.
• Be aw are of the d iffe ren t than usual steeri ng respo nse and adjust
your steering force accord ingly.
• Have t he pr oblem chec ked and set r igh t by a n Audi dea ler as soo n
as possib le .
[I) Tips
• When the engine is runni ng, neve r hold t he steering wheel turned
a ll the way to the r ig ht o r to t he left fo r longe r th an 1 5 seco nd s. The
powe r steering pump will over heat the hydraulic fluid if yo u keep
holding t he s teering w heel turne d all the w ay . This is likely to damage
the power steer ing system.
• If the powe r stee ring sys tem s ho uld fail entire ly, or if the engine
is not running (for examp le, while be ing towed), you will still be able
t o steer the vehicle. Howeve r,
considerably more effo rt will be
required to do so.
• If the powe r stee ring sys tem s ho uld have a leak, or is not func
tioning properly, contact your author ized Audi dealer immediately.
• Th e power s teeri ng system re quir es a specially fo rm ulated
hydraulic fluid. The power stee ring reservoir is the one located
f ar the st to the rea r on t he left side of the eng ine compa rtment
=> page 298 . The correct fluid level in the reservo ir is important for
pr op er f unctio ning o f the power steer ing.•

down steep sections on hills.
Unpaved roads and offroad
Drive slowly on unfamiliar roads and unknown offroad sections, and
loo k out for unexpected obstacles (e .g. potho les, rocks, t ree st umps,
etc.).
T o prevent the vehicle from bo ttoming and avoid dam age to the
underbody, you should drive straight across severe bumps in the
gro und with on ly one s ide of the vehicle so tha t on ly two of your
wheels cross the bumps.
Drive brisk ly throug h sandy or marshy offroad sections and do not
stop, if at all poss ible.
Driving through water
Your vehicle ca n drive at maximum wal king speed thro ugh stand ing
water if the gro und is firm enough . The
maximum water depth is
1 9. 7 in o r 500 mm (ve hicles w it h out air spr ings) or 2 1.1 in or
535 mm (vehicles with Adaptive Air Suspension*, at high level 2).
Driving on a slope
If you ever find yourself not able to climb a slope, do not try to t urn
around, drive bac k dow n in
rever se . Ot herw ise, you run t he ris k of

Trailer towing tips
Important to know
Your vehicle handles differe ntly when tow ing a tra iler because of the
additiona l weight and different we ight distribution. Safety, perfor
man ce and economy w ill greatly depend on how ca refu lly yo u load
your trailer and operate your rig.
Be fore you actua lly tow your tra ile r, prac tice turning, stopp ing and
back ing u p in a n area away from traffic. Keep pract ic in g until you have
become completely familiar with the way your vehicle -trailer combi
nation behaves and responds .
Backing up is diff icult and requ ires pract ice. Backing up w ith a trailer
gene rally requires s teer ing a ction opposi te to th at when ba cki ng up
your vehicle witho ut a trailer.
Maintain a greate r d istance between your ve hicl e and the one in front
of yo u. You will need more room to stop . T o compensate fo r the
trai ler, you will need a larger than normal turning radius .
W hen p assing, remember that you c annot acceler ate as fast as yo u
normally wou ld because of the added load. Make sure yo u have
enoug h room to pass. After passi ng, allow plen ty of room fo r yo ur
tra iler before changing lanes again .
Avoid jerky starts, sharp turns or rapid lane changes .
[ i ] Tips
• Do not tow a trai ler d uring the brea k-in perio d of your vehicle. •
If you tow a tra iler, your Aud i may require more frequent mai nte
n an ce due to the ex tra load:::::>
