fore-and-aft and lateral directions, the brake pressure and the
steering angle are all measured.
The direction in which the driver wishes to travel is determined with
the aid of the steering angle and vehicle speed and is continually
compared with the actual behavior of the vehicle. If the two do not
match, for example, when the vehicle starts hydroplaning on a wet
road, ESP will automatically brake the appropriate whee l to correct
the problem.
The vehicle is then stabi lized by the forces acting on the whee l during
braking. If the vehicle is
oversteering (rear tends to skid out of the
turn), the brakes are main ly applied on the wheel that is on the
outs ide of the curve. In the case of a vehicle that is
understeering
(tendency to slide out of the curve), the brakes are applied as needed
on the wheel that is on the inside of the curve or additionally on the
other wheels. An acoustic s ignal indicates when ESP brake application
cuts in=> &.
The system operates across the entire speed range in combination
with the ABS system ~
page 256 . If the Anti -Lock Brake System
(ABS) ma lfunctions, the ESP wi ll be out of action as well.
Activating
When you turn on the engine, ESP will automatically be activated and
will perform a self-test. As soon as the test is comp leted, the system
is in normal operating mode .
Offroad mode
ESP should normally be operated in normal mode because this
ensures maximum vehicle stability. If necessary, you can activate the
ESP offroad mode by pressing the button=>
page 252, fig. 220 to
obtain maximum traction and braking ability when driving off paved
roads at low speeds. In ESP offroad mode, the ESP indicator light
=> page 16 illuminates and the message ESP Offroad Caution!
Limited driving stability
appears briefly in the disp lay.
The ESP offroad mode can be useful in the following exceptiona l situ­
ations when slip or a highly effe ctive different ial loc king funct ion is
desirable. Examples:
Controls and equip­ ment Safety first Vehicle operation
•
when driving w ith tire chains,
• when driving in deep snow or on loose ground,
• when driving on uneven surfaces with the wheels severely
unloaded (articulation), and
• when rocking the vehicle loose a fter it has become stuck.
When the unusual situation is past, you should sh ift back to the
normal ESP operating mode by pushing the button again. The
message
ESP/ ASR on then appears briefly in the display.
Hill descent control
The hill descent control is switched on in ESP offroad mode. When
slowly descending steep gradients on loose ground or when the axles
are art iculated, hill descent control provides assistance by automati­
cally applying the brakes to keep vehicle speed constant. The vehicle
is also rende red easier to steer by select ive distribution of braking
force. Hill descent control intervenes when:
• the accelerator pedal is not pressed,
• the vehicle is travelling less than 12 mph (20 km/h),
• a steep gradient is detected,
• wheel behavior indicates loose ground or conditions with poor
adhesion (e.g. also axle articulat ion).
Hill descent control operates both dr iving forward and in reverse.
Active hi ll descent control is deactivated by pressing the accelerator
pedal until the conditions for activation already listed are met aga in .
& WARNING
• The Electronic Stabilization Program is nevertheless subject to
the laws of physics . It is particularly important to pay attention to
this fact on wet and slippery roads. It is therefore important that
you always adapt your driving to the condition of the road and
traffic conditions. Do not allow the increased safety provided by
the Electronic Stabilization Program system to lull you into
accepting additional safety risks. ..

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 .

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- ...

Lights
T he headl ight settings shou ld be chec ked with the tr ailer attached
before driving off. Check to make sure both vehicle and trailer lights
are wo rking properly.
Safety chains
Be sure tra ile r safety cha ins are p roperly connected from the t rai ler
to the hitch on the vehicle. Leave enough slack in the chains to perm it
tu rning corners . When you install sa fe ty ch ains, ma ke sure they will
not drag on the road when you are driving.
T he chains should cross under the trai ler tongue to prevent it from
dropping in case of separation from the h itch .
0 Note
If you are goi ng to tow a trai ler , you must activate the trai ler opera­
tion mode =>
page 180, "Towing a trailer". •
Driving instructior,s
Driving with a trailer always requires e xtra care and
consideration.
To obtain the best possib le handling of ve hicle a nd trailer ,
please note the following :
- Do not tow a loaded trailer when your car itself is not
loaded.
- Be especia lly careful when pass ing other vehicles .
- Observe speed limi ts.
- Do not drive at the maximum pe rmissible speed.
Controls and equip­
ment Safety first Vehicle operation
- Always apply brakes early.
- Mo
nitor the temperature gauge.
Weight distri but ion
T owing a loaded trailer with an empty car results in a highly unstable
distribution of we ight . If t his cannot be avoided , drive at very low
speeds only to avoid the risk of losing steering control.
A "balanced" rig is easier to operate and control. This means that the
tow veh icle shou ld be loaded to the extent poss ible and permissib le,
wh ile keeping the tra ile r as lig ht as poss ible unde r the ci rc u mstances.
Whe never possible, transfer some cargo to the luggage compart ­
me nt o f the tow vehicle while observing tongue load requirements
and vehicle loading considerations.
Speed
The higher the speed, the more d ifficult it becomes for the driver to
control the r ig . Do not dr ive at the maxim um permiss ible speed .
Reduce your speed eve n more if load, weather or w ind conditions are
unfavorable -particular ly when going downhill.
Reduce vehicle speed
immed iately if the tra ile r shows the slightest
sign of swaying.
Do not tr y to stop the s wayi ng by a ccele rating .
Observe speed lim its. In some areas, speeds for veh icles towing
trailers are lowe r than for regular veh icles .
Always apply brakes early. When driving downhi ll, shift into a lower
gear to use the engine brak ing effect to slow t he ve hicle . Use of the
brakes alone can cause them to overheat and fa il.
Coolant temperatur e
The coo lant temperature gauge=> page 10 must be observed care­
fu lly. If the needle moves close to the upper end of the sca le, reduce
speed immediately and/or turn off the air conditioner.
If the coo lant temperature warning light in the instrument clus ter
starts flash ing
- F- , pull off the road, stop and let the engine idle for
about two m inutes to prevent hea t buil d-up.
