Coolant temperature
indicator
The coolant temperature display @ > page 10,
fig. 3 only functions when the ignition is switch-
ed on. To reduce the risk of engine damage,
please observe the following notes about the
temperature ranges.
Cold range
If only the LEDs at the bottom of the gauge turn
on, the engine has not reached operating tem-
perature yet. Avoid high engine speeds, full accel-
erating and heavy engine loads.
Normal range
The engine has reached its operating tempera-
ture once the LEDs up to the center of the gauge
turn on. If the | indicator light in the instru-
ment cluster display turns on, the coolant tem-
perature is too high > page 17.
@) Note
— Auxiliary headlights and other accessories in
front of the air intake impair the cooling ef-
fect of the coolant. This increases the risk of
the engine overheating during high outside
temperatures and heavy engine load.

— The front spoiler also helps to distribute
cooling air correctly while driving. If the
spoiler is damaged, the cooling effect will
be impaired and the risk of the engine over-
heating will increase. See an authorized Au-
di dealer or authorized Audi Service Facility
for assistance.
Tachometer
The tachometer (2) > page 10, fig. 3 displays the
engine speed in revolutions per minute (RPM).
The beginning of the red zone in the tachometer
indicates the maximum permissible engine speed
for all gears once the engine has been broken in.
Before reaching the red zone, you should shift in-
to the next higher gear, choose the "D" or "S" se-
lector lever position, or remove your foot from
the accelerator pedal.
Engine speed limitation
Applies to: vehicles with engine speed limitation
If the BB indicator light turns on, the engine will
be automatically limited to the RPM displayed in
the instrument cluster. This protects the engine
from overheating.
The engine speed limitation deactivates once the
engine is no Longer in the critical temperature
range and you have released the accelerator ped-
al once.
If the engine speed limitation was activated by
an engine control malfunction, the B indicator
light also turns on. Make sure the engine speed
does not go above the speed displayed, for exam-
ple when downshifting. Drive to an authorized
Audi dealer or authorized Audi Service Facility im-
mediately to have the malfunction corrected.
@) Note
The needle in the tachometer may only be in
the red area of the gauge for a short period of
time before there is a risk of damaging the
engine. The location where the red zone be-
gins varies depending on the engine.
Odometer

Fig. 4 Instrument cluster: odometer and reset button
The trip odometer and odometer are displayed in
the status line ©) > page 10, fig. 3.
The trip odometer shows the distance driven
since it was last reset. It can be used to measure
short distances. The odometer shows the total
distance that the vehicle has been driven.
Resetting the trip odometer

> Press the reset button [0-9] on the instrument
cluster. The trip odometer will be reset to zero.
@) Tips
Distances are displayed in mi (miles) or km
(kilometers).

Outside temperature
display
The outside temperature is displayed in the sta-
tus line ® page 10, fig. 3.
If your vehicle is stationary or if you are driving at
very low speeds, the temperature displayed in
the instrument cluster may be slightly higher
than the actual temperature outside due to heat
radiating from the engine.
At temperatures below 41 °F (+5 °C), a snowflake
symbol appears in front of the temperature dis-
play > A.

ZA\ WARNING
Do not assume the roads are free of ice based
on the outside temperature display. Be aware
that there may be ice on roads even when the

11

Instrument cluster

outside temperature is around 41 °F (+5 °C)
and that ice can increase the risk of accidents.


Fuel level
The display @ > page 10, fig. 3 only works when
the ignition is switched on. When the display has
reached the reserve mark, a red LED turns on and
the i indicator light turns on > page 19.
For
the tank capacity in your vehicle, refer to the
Technical Data > page 285.
@ Note
Never drive until the tank is completely emp-
ty. The irregular supply of fuel that results
from that can cause engine misfires. Uncom-
busted fuel will then enter the exhaust sys-
tem. This can cause overheating and damage
to the catalytic converter.

— If the brake fluid level is below the MIN
marking, it can impair the braking effect and
driving safety, which increase the risk of an
accident. Do not continue driving. See an au-
thorized Audi dealer or authorized Audi
Service Facility for assistance.
— If the brake system indicator light turns on
together with the ABS and ESC indicator
lights, the ABS/ESC regulating function may
be malfunctioning. Functions that stabilize
the vehicle are no longer available. This
could cause the rear of the vehicle to
swerve, which increases the risk that the ve-
hicle will slide. Drive carefully to the nearest
authorized Audi dealer or authorized Audi
Service Facility and have the malfunction
corrected.

The coolant level is too low.
Stop driving and switch the engine off. Check the
coolant level > page 234.
— If the coolant level is too low, add coolant
=> page 234. Only continue driving once the in-
dicator light turns off.
|_| Coolant temperature: too high. Let engine

continue driving the vehicle. See an authorized
Audi dealer or authorized Audi Service Facility
for assistance.

ZA\ WARNING
— Never open the hood if you can see or hear
steam or coolant escaping from the engine
compartment. This increases the risk of
burns. When you no longer see or hear
steam or coolant escaping, you may open
the engine compartment with caution.
— The engine compartment in any vehicle can
be a dangerous area. Stop the engine and al-
low it to cool before working in the engine
compartment. Always follow the informa-
tion found in > page 227, General informa-
tion.
() Note

Driving



— Power is still transferred to the wheels when
the engine is running at idle. To prevent the
vehicle from “creeping”, you must keep your
foot on the brake when the engine is run-
ning and the selector lever is in the "D", "S"
or "R" position or “tiptronic” mode is select-
ed.
— Do not inadvertently press the accelerator
pedal when the vehicle is stationary. Other-
wise the vehicle will start to move immedi-
ately, even if the parking brake is set. This
could result in a crash.
— Do not press the accelerator pedal when
changing the selector lever position while
the vehicle is stationary and the engine is
running.
— Never engage the R or P selector level posi-
tions while driving. It could cause a crash.
— Before driving down a steep slope, reduce
your speed and shift into a lower gear with
“tiptronic”.
— Do not ride the brakes or press the brake
pedal
too often or too long when driving
downhill. Constant braking causes the
brakes to overheat and can substantially re-
duce braking performance, increase braking
distance, or cause complete failure of the
brake system.
— If you must stop on an incline, always hold
the vehicle in place with the foot brake or
parking brake to prevent it from rolling
back.
— Never hold the vehicle on an incline with a
slipping clutch. The clutch opens automati-
cally when it becomes too hot from the over-
load. The | indicator light turns on and a
message appears > page 67 when the
clutch is overloaded.
— If the engine must run while you are work-
ing in the engine compartment with the
hood open, make sure a gear is not engaged.
The selector lever must be firmly in the
P position and locked in place and the park-
ing brake must be set > page 227. Other-
wise, the vehicle could begin moving when
increasing the engine speed, even with the
parking brake set.

CG) Note
— When stopping on an incline, do not try to
hold the vehicle in place by pressing the ac-
celerator pedal while a driving gear is se-
lected. This can cause the automatic trans-
mission to overheat and can damage it. Set
the parking brake or press the brake pedal
to prevent the vehicle from rolling.
— Allowing the vehicle to roll when the engine
is stopped and the selector lever is in the N
position will damage the automatic trans-
mission because it is not lubricated under
those circumstances.
— The transmission can overheat and be dam-
aged under certain driving and traffic condi-
tions such as frequent starts, creeping for a
long time, or stop-and-go traffic. When the
fs} or & indicator light turns on, stop the
vehicle at the next opportunity and let the
transmission cool > page 67.
— Allowing the vehicle to roll when the engine
is stopped will damage the S tronic trans-
mission because it is not lubricated
=> page 274, Towing.
@) Tips
For safety reasons, the parking brake is re-
leased automatically only when the driver's
safety belt is fastened.
Hill descent control
The hill descent control system assists the driver
when driving down hills.
Hill descent control is activated when the selec-
tor lever is in the "D" or "S" position and you
press the brake pedal. The transmission automat-
ically selects a gear that is suitable for the hill.
Hill descent control tries to maintain the speed
that was selected at the time of braking, within
physical and technical limitations. If may still be
necessary to adjust the speed with the brakes.
Because hill descent control cannot shift down
farther than 3rd gear, it may be necessary to shift
into tiptronic mode in very steep areas. In this

Intelligent Technology

@) 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.
@) 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 235.
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.
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.
G@) Tips
If the 12 or al 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
both under normal driving conditions and on
snow and ice. Always read and follow safety pre-
cautions > A\.
Winter tires
By using all wheel drive, your vehicle has good
forward motion with standard tires in winter con-
ditions. However, in winter we recommend using
winter or all season tires on all four wheels, be-
cause this will improve the braking effect.
Snow chains
If there are snow chain laws, snow chains must
also be used on vehicles with all wheel drive
=> page 255, Snow chains.
Replacing tires
For vehicles with all wheel drive, only wheels with
the same rolling circumference should be used.
Avoid using tires with different tread depths
=> page 247, New tires or wheels.

Add more coolant if necessary.
> Close the cap securely.
Coolant loss usually indicates that there is a leak.
Immediately drive your vehicle to an authorized
Audi dealer or authorized Audi Service Facility
and have the cooling system inspected. If the
cooling system is not leaking, coolant loss can re-
sult from the coolant boiling due overheating
and then being forced out of the cooling system.

compartment. This increases the risk of
burns. The cooling system is under pressure.
When you no longer see or hear steam or
coolant escaping, you may open the engine
compartment with caution.
— When working in the engine compartment,
remember that the radiator fan can switch
on even if the ignition is switched off, which
increases the risk of injury.
— Coolant additive and coolant can be danger-
ous to your health. For this reason, store the
coolant in the original container and away
from children. There is a risk of poisoning.


@) Note
Do not add coolant if the expansion tank is
empty. Air could enter the cooling system and
damage the engine. If this is the case, do not
continue driving. See an authorized Audi deal-
er or authorized Audi Service Facility for assis-
tance.
