reduce the risk of injury, do not place your
foot under the brake pedal.
@) Note
— Never let the brakes “rub” by pressing the
pedal lightly when braking is not actually
necessary. This can cause the brakes to over-
heat and increases braking distance and
causes wear.

— Before driving on long stretches with steep
hills, reduce the vehicle speed and shift to a
lower gear to use the engine braking effect.
This reduces the load on the brakes. If you
need to brake additionally, brake in intervals
and not continuously.
G) Tips
— If you retrofit your vehicle with a front spoil-
er, wheel covers or similar items, make sure
that the air flow to the brakes is not ob-
structed. Otherwise the brake system can
overheat.
— Also refer to the information about brake
fluid > page 239.
Steering
Electromechanical steering supports the driver's
steering movements by electronically adapting
the power steering depending on the vehicle
speed. The settings depend on the selected Audi
drive select* mode.
Dynamic steering
Applies to: vehicles with dynamic steering
The driving dynamic and driving stability are in-
creased by the steering ratio based on the speed.
At reduced speeds, steering is direct in order to
provide agile steering behavior and keep the
steering effort as minimal as possible when the
driver is maneuvering the vehicle. This sets the
steering to be less sensitive at higher speeds in
order to provide improved vehicle control.
Messages
a Steering: malfunction! Please stop vehicle
The power steering may have failed. Adapt your
driving style immediately to compensate for the
fact that it may be more difficult to turn the
steering wheel, and stop your vehicle in a safe lo-
cation as soon as possible. Do not continue driv-
ing. See an authorized Audi dealer or authorized
Audi Service Facility for assistance.
a Steering: malfunction! You can continue
driving
There is a malfunction. Steering may be more dif-
ficult or more sensitive. Adapt your driving style.
Have the steering system checked immediately
by an authorized Audi dealer or authorized Audi
Service Facility. Please note that the red indicator
light may turn on after restarting the engine. Do
not continue driving if it does.
Dynamic steering: correcting steering wheel
Position
The steering is reinitializing. The steering wheel
will move easily after starting the vehicle. Reiniti-
alization might be necessary if the steering wheel
was moved while the engine was switched off.
The display turns off if the initialization was suc-
cessful.
@) Tips
— If there is a malfunction, the steering wheel
may be crooked when driving straight.
—Ifthe a or Ee indicator light only stays on
for a short time, you may continue driving.
All wheel drive (quattro)
Applies to: vehicles with all wheel drive
In all wheel drive, all four wheels are powered.
General information
In all wheel drive, the driving power is divided be-
tween all four wheels. This happens automatical-
ly depending on your driving behavior as well as
the current road conditions. Also see > page 86,
Electronic stabilization control (ESC).
The all wheel drive concept is designed for high
engine power. Your vehicle is exceptionally pow-
erful and has excellent driving characteristics

Checking and Filling



— Never open the cap on the coolant expan-
sion tank when the engine is warm. The
cooling system is under pressure.
— To protect your face, hands, and arms from
hot steam or coolant, cover the cap with a
thick cloth when opening.
— Do not remove the engine cover under any
circumstances. This increases the risk of
burns.
— Due to the risk of electric shock, never touch
the ignition cable or other components in
the electronic high-voltage ignition system
when the engine is running or is starting.
— If a gear is engaged while the vehicle is sta-
tionary and the engine is running, do not
press the accelerator pedal inadvertently.
Pressing the accelerator pedal will cause the
vehicle to move, and this could result in an
accident.
— If inspections or repairs must be performed
while the engine is running, moving compo-
nents (such as the ribbed belt, generator,
and radiator fan) pose an additional risk.
— Set the parking brake first and select the
“p” (Park) selector lever position.
— Always make sure that no parts of the
body, jewelry, ties, loose clothing, and
long hair can be caught in moving engine
components. Before any work, always re-
move any jewelry and/or ties, tie back long
hair, and make sure all clothing fits close
to the body to reduce the risk of anything
becoming caught in engine components.
— Pay attention to the following warnings list-
ed when work on the fuel system or on the
electrical equipment is required.
— Do not smoke.
— Never work near open flames.
— Always have a working fire extinguisher
nearby.
— All work on the battery or electrical system
in your vehicle can result in injuries, chemi-
cal burns, accidents, or burns. Because of
this, all work must be performed only by an
authorized Audi dealer or authorized Audi
Service Facility.
— Limit your exposure to exhaust and chemi-
cals to as short a time as possible.

Service Facility for assistance.
— If the brake fluid is old, bubbles may form in
the brake system during heavy braking. This
could impair braking performance and driv-
ing safety, which increases the risk of an ac-
cident.
— The brake fluid in your vehicle must meet
the standard VW 501 14 and is available at
an authorized Audi dealer or authorized Au-
di Service Facility. If this brake fluid is not
available, another high-grade brake fluid of
equivalent quality may be used, and it must
meet the U.S. Federal Motor Vehicle Stand-
ard (FMVSS) 116 DOT 4, Class 6.

@) Note
— If the brake fluid level is above the MAX
marking, brake fluid may leak out over the
edge of the reservoir and result in damage
to the vehicle.
— Do not allow any brake fluid to come into
contact with the vehicle paint, because it
will corrode the paint.
Electrical system
If the = or fl] indicator light turns on, there is a
malfunction in the generator, the battery, or the
vehicle electrical system.
= Electric system: malfunction! Battery is not
being charged

Battery
Battery general information
Because of the complex power supply, all work on
batteries such as disconnecting, replacing, etc.,
should only be performed by an authorized Audi
dealer or authorized Audi Service Facility > A\.
Multiple batteries with different technologies
may be installed in your vehicle:
— Vehicle battery (for example, for starting the
engine, basic power supply) > page 241, Lead
battery or > page 241, Other battery types
— Auxiliary battery (for example, for recuperation
or optional equipment) > page 241, Other bat-
tery types
Not running the vehicle for long periods of
time
The battery will gradually drain if the vehicle
does not run for long periods of time. To ensure
that the vehicle can still be started, the electrical
equipment will be limited or switched off. Some
convenience functions, such as interior lighting
or power seat adjustment, may not be available
under certain circumstances. The convenience
functions will be available again when you start
the
engine.
Even when electrical equipment is switched off,
the equipment can still drain the battery if the
vehicle is not driven for long periods of time.
Deep draining results in a chemical reaction that
destroys the inside of the battery. The battery
must be charged every month to prevent this
= page 242. Contact an authorized Audi dealer or
authorized Audi Service Facility for more infor-
mation.

technically referred to as the vehi-
cle’s Gross Vehicle Weight Rating
(“GVWR”).
The “GVWR” includes the weight
of the basic vehicle, all factory in-
stalled accessories, a full tank of
fuel, oil, coolant and other fluids
plus maximum load. The maxi-
mum load includes the number of
passengers that the vehicle is in-
tended to carry (“seating capaci-
ty”) with an assumed weight of
150 lbs. (68 kg) for each passen-
ger at a designated seating posi-
tion and the total weight of any
luggage in the vehicle.
The Gross Axle Weight Rating
(“GAWR’”) is the maximum load
that can be applied at each of the
vehicle’s two axles.
The fact that there is an upper
limit to your vehicle’s Gross Vehi-
cle Weight Rating means that the
total weight of whatever is being
carried in the vehicle is limited.
The more passengers in the vehi-
cle or passengers who are heavier
than the standard weights as-
sumed mean that less weight can
be carried as luggage.
The Gross Vehicle Weight Rating
and the Gross Axle Weight Rating
are listed on the safety compli-
ance sticker label located on the
driver’s side B-pillar.

Z\ WARNING
Overloading a vehicle can cause
loss of vehicle control, a crash
or other accident, serious per-
sonal injury, and even death.
—Carrying more weight than
your vehicle was designed to
carry will prevent the vehicle
from handling properly and in-
crease the risk of the loss of
vehicle control.
—The brakes on a vehicle that
has been overloaded may not
be able to stop the vehicle
within a safe distance.
—Tires ona vehicle that has
been overloaded can fail sud-
denly, including a blowout and
sudden deflation, causing loss
of control and a crash.
—Always make sure that the to-
tal load being transported
does not make the vehicle
heavier than the vehicle’s

Gross Vehicle Weight Rating.
