[ i] Tips
• You can apply the parking brake at any time - even with the igni­
tion turned off. The ignition must be turned on in order to release
the parking brake .
• Occasional noises when the parking brake is applied and
released are normal and are not a cause for concern .
• The parking brake goes through a self -test cycle at regular inter ­
vals - when the vehicle is parked . Any associated noises are
normal. •
Parking
To prevent a parked vehicle from rolling away, there are a
few things you should do.
When you park your vehicle, do the following
- Stop the vehicle using the brake pedal.
- Pull the switch to apply the electromechanical parking
brake.
- Move the selector lever into the
P position ~& .
- Switch off the engine and remove the ignition key from
the ignition lock.
When you park your vehicle on hills, do the
following - Stop the vehicle using the brake pedal.
- Pull the switch to apply the electromechanical parking
brake.
- If you are parking headed downhill, turn the front wheels
toward the curb. - If you are
parking headed uphill, turn the front wheels
awayfrom the curb.
- Move the selector lever into the P position .
- Switch off the engine and remove the ignition key from
the ignition lock.
& WARNING
This is how you can reduce the risk of injury when leaving your
vehicle.
• Never park the vehicle where it can come in contact with dry
grass, spilled fuel or any other flammable materials.
• When parking on hills, always turn the wheels so that the front
wheels will first roll into the curb, if the vehicle should start to roll.
• Never allow anyone -especially small children -to remain in the
vehicle when it is locked. Locked doors make it more difficult for
rescuers to access the passenger compartment in the event of an
emergency. Danger to life!
• Never leave children unsupervised in the vehicle. Children
could release the parking brake or move the gearshift lever out of
gear. The vehicle could start to roll away and cause an accident.
• No matter what the season is, the temperature in a parked
vehicle can reach dangerous levels.
0 Note
• Please exercise care when you park your vehicle in parking areas
with parking barriers or curbs. Parking barriers and curbs vary in height and could damage your bumper and related components as
the front of your vehicle moves over a barrier or curb that is too
high, as you park or as you back out of a parking spot. In order to be
sure that no such damage can occur, you may wish to stop short of
having the front tires of your car touch the parking barrier or curb . ..,_

Adaptive Air Suspension
Adaptive Air Suspension and
Damping
A pplies to veh icles: with Adaptive Air Suspens ion
Description
Adaptive Air Suspension and damping can be regulated
and they adapt automatically to a request from the driver
and the driving situation at the time.
Adaptive Air Suspension is an electronically controlled springing
and damping system . Th is chassis system makes it easier on the
driver by adapting to the particular situation through imperceptible
control processes.
The
Adaptive Air Suspension component regulates ground clear ­
ance depending on vehicle speed, load condition and driver input.
When the system is in automatic mode, accelerating to a speed above a predetermined limit will make the vehicle lower itself. On
the other hand, driving more slowly results in the vehicle raising
again at specific speeds.
The
damping component provides individual control of the
damping forces. For example, with damping characteristics set to
provide greater comfort, damping is set somewhat harder for a brief
period only as required, for example, when going around a curve or
over rough road surfaces as well as when braking.
Settings
Adaptive Air Suspension provides the driver with the opportunity to
set the chassis characteristics also to their individual preference.
With the driving modes
standard, automatic and dynamic the driver
has three chassis settings available, ranging from comfort to sporty .
In addition,
lift provides a fourth mode which can be selecting for
driving over poor stretches of road :::::,
page 183, "Chassis controls". The modes are set in
MMI:::::,
page 183.
& WARNING
The height of the parked vehicle can change due to temperature
fluctuations or changes in load.
0 Note
• Whenever you park your vehicle, always make sure there is
adequate clearance above and below the vehicle. The height of the parked vehicle can change as the result of temperature fluctuations,
changes in load condition and changes in the driving mode (ground
clearance!.
• If the vehicle is being transported (e.g. by tow truck, train, ship,
etc.), mount the tie -down chains/cables over the running surface
(circumference) of the tires . Never secure the vehicle by the axle, the
suspension struts or the front or rear towline eye. For technical
reasons, the pressure in the suspension struts may change during
the transport, which could result in the vehicle no longer being
secured properly.
• To prevent damage to the vehicle underbody, remember that
your vehicle is not an off-road vehicle, even in the "lift" mode. The
ground clearance is insufficient for this type of operation.
• If you are going to tow a trailer, you must activate the trailer oper­
ation mode :::::,
page 184.
[ i] Tips
Before you raising your vehicle using the vehicle jack (for example,
when changing a flat tire) you must activate the jacking mode
=> page 184. •

with less grip, gradually increase the pressure on the accelerator
pedal until the car starts to move.
Overheating of brakes
To prevent the disc brake of the braked wheel from overheating if
subjected to excessive loads on this wheel, the EDL cuts out tempo ­
rarily. The vehicle remains operational and behaves in the same way
as a vehicle without EDL.
As soon as the brake has cooled down, EDL switches on again auto ­
matically.
& WARNING
• When accelerating on slippery surfaces, such as on ice or snow,
always be careful when depressing the accelerator pedal. Even
with the EDL working, the drive wheels can spin and reduce your
ability to control your car. Risk of crash!
• The increased safety afforded by EDL does not mean that you
can take safety risks. Always adapt your driving style to the road
conditions and traffic situation.
[ i] Tips
If a fault occurs in the ABS, the EDL is also not functioning. This is
indicated by the ABS warning light=>
page 22. •
Ant"-Slip Regulation System (ASR)
The Anti-Slip Regulation System prevents the driven
wheels from spinning when the car is accelerating.
General notes
The Anti-Slip Regulation System (ASR) is integrated in the electronic
stabilization program (ESP). When the vehicle starts up and acceler ­
ates, the wheels are prevented from spinning by adjusting the engine power to match the amount of grip available from the road
surface.
How the system works
ASR
performs automatically, i.e. without the driver's intervention.
With the aid of the ABS sensors=>
page 262, ASR monitors the
speed of the driven wheels. If the wheels start to spin, the engine
torque is reduced automatically until the tires find enough grip to
lock onto the road surface. The system is active across the entire
speed range.
Th e ASR works in conjunction with the ABS. If a malfunction should
occur in the ABS, the ASR will also be out of action.
Activating
The ESP is automatically activated when the engine is started and it
performs a self -test . You can activate a deactivated ASR if required
by pressing the =>
page 258, fig. 225 button . When it is activated,
the message
ESP/ASR on appears briefly in the display. Vehicles
with front-wheel drive a deactivated ASR automatically re-activates
itself at a speed of 40 mph (70 km/h) .
Deactivating
You can deactivate the ASR if required by pressing the button (for
less than 3 seconds)=>
page 258, fig. 225. With the ASR deactivated,
the ESP check light comes on, see=>
page 19. The message ASR off
appears in the display as well. On vehicles with front-wheel drive:
deactivation is possible only up to 30 mph (50 km/h) for safety
reasons . Vehicles with all -wheel drive: the ASR can be deactivated
at any speed .
The ASR should normally be activated all the time. Only in certain
exceptional situations when some slip is desirable does it make
sense to deactivate the ASR. Examples:
• when driving with tire chains
• when driving in deep snow or on loose ground and
• when rocking the vehicle loose after it has become stuck .

When the abnormal situation is over, you should activate the ASR
again.
& WARNING
The increased safety afforded by ASR does not mean that you can
take safety risks. Always adapt your driving style to the road
conditions and traffic situation.
[ i] Tips
To ensure that the ASR works properly, all four wheels must be fitted
with identical tires. Any differences in rolling radius of the tires can
cause the system to reduce engine power when this is not desired.

Braking
General information
What affects braking efficiency?
Operating conditions and driving habits
The brakes on today's automobiles are still subject to wear,
depending largely on operating conditions and driving habits~& .
On vehicles which are driven mostly in stop-and-go city traffic or
which are driven hard, the brake pads should be checked by your
authorized Audi dealer more often than specified in the
Mainte­
nance
& Warranty booklet.
On steep slopes, you should use the braking effect of the engine.
This way, you prevent unnecessary wear on the brake system. If you
must use your brakes, do not hold the brakes down continuously.
Pump the brakes at intervals.
Controls and equip­
ment Safety first Vehicle operation
Intelligent technology
Moisture or road salt
If
you are driving faster than 50 mph (80 km/h) and the windshield
wipers are on, the brake pads will briefly touch the brake discs in regular intervals so as to improve reaction time when braking on
wet surfaces. You, the driver, will not notice anything.
Under certain conditions, for example, when driving through water
or very heavy rain, or even after washing your vehicle, the braking
effect can be reduced due to moisture (or in freezing conditions ice)
on the brake pads. A few careful brake applications should dry off
the brake pads or remove any ice coatings .
The effectiveness of the brakes can be reduced when the vehicle is driven on a salt-covered road and the brakes are not used. Here too,
you should clean off accumulated salt coating from brake discs and
pads with a few careful applications of the brake ~& .
Corrosion
There may be a tendency for dirt to build up on the brake pads and
corrosion to form on the discs if the car is not driven regularly or
only for short trips with little use of the brakes.
If the brakes are not used frequently, or if corrosion has formed on
the discs, it is advisable to clean off the pads and discs by braking
firmly a few times from a moderately high speed~&.
Faults in the brake system
If you should notice a sudden increase in brake pedal travel, then
one of the two brake circuits may have failed~& .
Low brake fluid level
Malfunctions can occur in the brake system if the brake fluid level is
too low . The brake fluid level is monitored electronically .
& WARNING
• 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 risk -you may cause an accident!

• Be aware of the different than usual steering response and
adj ust you r steer ing for ce accordingly.
• Have the problem checked and set right by an Audi dealer as
s o on as possible .
[ i ] Tip s
• When th e engine is running, never hold the steering whee l
turned all the way to the right or to the left for longer than 15 seconds. The power steering pump will overheat the hydrau lic
fluid if you keep ho lding the steering wheel turned all the way. This
is like ly to damage the power steering system.
• If the power steering system should fail entirely, or if the engine
is not running (for example, while being towed), you wil l still be able
to steer the vehicle . However,
considerably more effort will be
required to do so.
• If the power steering system should have a leak, or is not func ­
tioni ng properly, contact your authorized Audi dealer immediately.
• The power steering system requires a specially formulated
hydraulic fluid . The power steering reservoir is the one located most
forward on the left side of the engine compartment~
page 298. The
correct fluid level in the reservoir is important for proper func ­
tioning of the power steering.
App lies to vehic les: with A ll Wheel Dr ive
Dr iving with your quattro®
With All Wheel Drive, all four wheels are driven.
Gen era l i nfo rm ati on
With All Wheel Drive, power is d istr ibuted to all four whee ls. Th is
happens automatica lly depending on your driving style and the
road conditions at the time. See also ~
page 259, "Electronic differ ­
entia l lock (EDU".
Wint er tir es
When driving in the winte r, your vehicle with All Wheel Drive has an
advantage, even with regular tires. In winter road conditions it may
be advisable to mount winter tires (or all -season tires) for improved
driveability and braking: these tires must be mounted on
a ll fou r
wh eel s.
See also ~ page 329, "Winter tires".
Tire chains
Where tire chains are mandatory on certain roads, this normally
a lso app lies to veh icles with A ll Wheel Drive~
page 330, "Snow
chains".
R epl acing w hee ls/t ires
Vehicles with All Wheel Drive must always have tires of the same
size. Also avoid tires with different tread depths . For details see
page ~
page 325, "New tires and replacing tires and wheels" .
Off-R oa d dri ving?
Your Audi does no t have enough ground c learance to be used as an
off -road vehic le. It is therefore best to avoid rough tracks and
uneven terrain as much as possible . Also refer to~
page 269.

Driving and environment
The first 1,000 miles (1,500 km) and afterwards
!\Jew engine
The engine needs to be run-in during the first 1,000 miles
(1,500 km).
F o r th e fir st 600 mil es (1,000 kilomet ers):
Do not use full throttle.
- Do not drive faster than 3/4 of the top speed marked on
the speedometer.
- Avoid high engine speeds .
From 600 t o 1,000 mil es (1,000 t o 1,500
kil om eter s):
- Speeds can
gradually be i ncreased to t he maximum
permiss ible road or engine speed .
During and aft er br eak-in p eri od
- Do not rev the engine up to high speeds when it is cold. This applies whether the transm ission is in N (Neutral) or
1n gear.
Aft er the br eak-in p eriod
- D o not exceed max imum e ngine speed unde r any
circumstances.
- Upshift into the next higher gear
before reac hing the red
area at the end of the tachome ter scale ~
page 13 .
Controls and equip­
ment Safety first Vehicle operation
Dri
ving and environm ent
During the first few hours of driving, the eng ine's internal friction is
higher than later when all the moving parts have been broken in.
How well this break -in process is done depends to a considerable
extent on the way the vehicle is driven during the first 1,000 miles
(1,500 ki lometers).
0 Not e
Extreme ly high engine speeds are automatically reduced. However,
these rpm limits are programmed for an engine well run-in, not a
new engine .
~ For the sake of the environment
Do not drive with unnecessarily high engine speeds -upshifting
early saves fuel, reduces noise and protects the environment .
New tires
If your v ehic le is running on new tires, driv e particularly
carefu l for the first 350 miles (500 ki lometers) after fitting.
& WARNING
N ew tir es tend to be slipp ery and mu st al so be "broken -in ". B e

- Lack of proper maintenance as wel l as improper use of the
vehic le wi ll impair the func tion of the emission con tro l system
and could lead to damage.
<£> For the sake of th e envir onm ent
Even when the Emission Control System is operating properly, the
exhaust gas can have a su lfur -like exhaust gas smell under some
operating states . This depends on the sulfur content of the fuel
being used. Using a different brand of fue l may help, or filling the
tank with lead-free super grade gasoline. •
Avoid damaging the vehicle
When you are driving on poor roads, or over curbs, steep ramps,
etc., make certain that low- lying parts such as spoi lers and exhaust
system parts do not bottom out and get damaged.
This is especially true for vehicles with low-slung chassis (sports

Operate your vehicle economically
and minimize pollution
General
Your personal style of driving will determine the economy
of your vehicle, as well as exhaust and noise levels.
Fuel economy, environmental impact, and wear on your engine,
brakes and tires largely depend on three factors:
• your personal driving style
• operating cond itions
• technica l limitations

If you anticipate what you need to do next and drive economica lly,
you can easily cut your fuel consumption by 10 -15 percent . This
section wil l give you some tips on how you can help the environ­
ment and your pocketbook.
[ i ] Tips
The consumption estimates as published by ENV IRONMENTAL
PRO TEC TION AGENCY (EPA) and Transport Canada may not corre ­
spond to your actua l consumption on the road, which wi ll vary
depending upon vehic le load and speed, road and weather condi­
tions, trip length, etc. •
Drive smoothly and keep a lookout ahead
Vehicles use the most fuel when they ore accelerating.
-Avoid unnecessary accelerat ing and braking.
Vehicles use the most fuel when they are accelerating . If you antici­
pate what is going to happen next, you wi ll need to brake less and,
thus, acce lerate less. Let the vehicle coast whenever possib le - for
examp le when you see that the next traffic light is red. •
Avoid full throttle
Driving at moderate speeds saves fuel and improves your
mileage.
-Try and keep well below your car 's max imum speed.
Acce lerating gently reduces fue l consumption , engine wear, and
does not disturb the environment.
Fue l consumption, exhaust emissions and engine noise increase
disproportionately at high speeds . If you drive at approximate ly
three quarters of top speed, fuel consumption wil l be reduced by

Operating instructions
Max im um tra iler weight
A trailer for your vehicle is limited to a typical class 1 or class 2
trailer.
T ra ile r l oa d di stributio n
Be sure the load in the trailer is he ld securely in place to prevent it
from shifting forward, backward or sideways .
Never allo w a passe nger to r ide in a tr aile r~ & in "Driving instruc­
tions" .
Engin e c oolin g sys te m
Towing a trailer makes the eng ine work harder. It is important that
the cooling system's performance is up to the additiona l load. Make
sure that the coo ling system has enough fluid .
Tire pr ess ure
When towing a trailer, inflate the tires of your vehicle to the co ld tire
pressure listed under "Full load" on the labe l located either on the
driver's side B -pil lar (visible when the door is open) or inside the fuel
filler flap . Inflate trai ler tires to trai ler and tire manufacturers' spec­
ifications.
L ig ht s
The head light settings should be checked wit h the trai ler attached
before driving off. Check to make sure both vehicle and trai ler lights
are working properly .
Safe ty c ha in s
Be sure traile r safety chains are properly connected from the trailer
to the hitch on the vehicle. Leave enough slack in the chains to
perm it turning corners . When you i nsta ll safety chains, make sure
they will not drag on the road when you are driving.
T he chains should cross under the trailer tongue to prevent it from
dropping in case of separat ion from the hitch.

Driving instructions
Driving with a trailer always requires extra care and
consideration.
To obtain the best possible handling of veh icle and trailer,
please note t he following :
- Do not tow a loaded trailer when your car itself is not
loaded.
Be espec ia lly careful whe n passing other vehicles.
- Observe s peed limits .
Do not drive at the maximum permiss ible speed .
Always apply brakes ear ly.
Moni tor t he temperature ga uge.
Weight distr ibution
Towing a loaded trailer with an empty car results in a highly
unstable distr ibution of weight. If this 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 vehicle should be loaded to the extent possible and perm is ­
s ib le, while keeping the trailer as light as possib le under the circum ­
stances . Whenever possible, transfe r so me cargo to t he luggage
compartment of the tow vehicle whi le observing tongue load
requirements and vehicle loading considera tions . .,
