- To downshift, touch the button on the left Q.
- To upshift, touch the button on the right G).
The shift buttons a re activated when the selector lever is in D, Sor in
the manual shift program (t iptronic).
Of course, you can continue to use the manual shift program with the
selector lever on the center console. •
Automatic transmission malfunction I
In the event of a system malfunction, the automat ic transmission
switches to emergency operation mode .
., Gearbox malfunction: you can continue driving
You can continue to drive the vehicle. See an authorized Audi dealer
or other qualified workshop at the next opportunity .
Gearbox malfunction: you can continue driving (limited
functionality )
There is a serious system malfunction:
• The program shifts only into certain gears.
• The engine may stall.
• It is not poss ible to restart the engine if it has been switched off.
• Continuing to drive could result in subsequent damage .
0 Note
If the transmission switches to fail-safe mode, you should take the
vehicle to an authorized Audi dealership as soon as poss ible to have
the condition corrected. •
Emergency release for selector lever
If the vehicle's power supply fails, the selector lever can
be released in an emergency.
Fig. 165 Emergency
release for selector
lever
The emergency release is located under a rubber mat.
- Carefully lift the rubber mat with a screwdriver or some­
thing similar => fig. 165.
- You now have access to a rocker switch . Using a screw­
dr iver or similar object, press the rocker switch down and
hold it down. ._

_________________________________________ 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.•
Dr"v ing witr your quattro®

Wit h All Wheel Drive, all four wheels are d riven .
General information
With All Wheel Drive, power is dist ribu ted to all fo ur wheels. This
hap pens a utomat ically depending o n your dr iv ing style and t he road
conditions at the time. See also =>
page 254, "Electronic different ia l
lock (EDL)" .
Winter tires
When d riving in the win ter, your vehicle with A ll Whee l Dr ive has an
advantage, even w ith regula r tir es. In w inter road con ditions i t may
be advisable to mou nt wi nte r ti res (or all-seaso n tires) for improve d
dr iveability and b raking: these tires m ust be mounted on
all four
wheels .

page 331, "Snow chains" .
Replacing wheels/tires
Vehicles wit h All W heel Dr ive must a lways have t ires of the same si ze .
Also avoid tires with different tread depths. For details see page
=> pa ge 32 6, "N ew tires and rep lacing tires and wheels".
& WARNING
Always adjust your driving to road and traffic conditions . Do not
let the extra safety afforded by All Wheel Drive tempt you into
taking extra risks.
• Although the All Wheel Drive is very effective, always
remember that braking capacity is limited by tire traction. You
should therefore not drive at excessive speeds on icy or slippery
road surfaces.
• On wet road surfaces, be careful not to drive too fast because
the front wheel s could begin to slide on top of the water (aqua- ...
