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.

4S1012721BA
Instrument cluster

— 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 [9-9] 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 290.
@ 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.

Driving


— The vehicle can roll even if the ignition is
switched off.
— Power is still transmitted to the wheels
when the engine is running at idle. To pre-
vent the vehicle from “creeping”, you must
keep your foot on the brake in all selector
lever positions (except "P" and "N") when
the engine is running.
— Before opening the engine compartment lid,
select the "P" selector lever position and set
the parking brake. This reduces the risk of
an accident. Always read and follow the ap-
plicable warnings > page 229, General in-

formation.
@ Tips
If you accidentally select "N" while driving,
take your foot off the accelerator pedal and
wait for the engine to slow down to idle be-
fore selecting "D" or "S".
Starting the engine

> The Por N position must be selected.
Starting from a stop
> Press and hold the brake pedal.
> Start the engine > page 60.
> Press the locking button @ on the selector lev-
er and select the D/S or R position > page 67.
> Wait a moment until the transmission shifts.
You will notice a slight movement when the
gear engages.
> Release the brake pedal and press the accelera-
tor pedal > A\.
Various convenience functions are available for
starting on hills > page 66.
Stopping temporarily
> Press the brake pedal to stop the vehicle, for
example at a traffic light. Do not press the ac-
celerator pedal when doing this.
> To prevent the vehicle from rolling when you
start driving, set the parking brake when stop-
ping on steep hills > A\ and >@).
> The parking brake will release automatically
and the vehicle will start moving once you press
the accelerator pedal.
Stopping or parking
If the selector lever is not in the "P" position
when you open the driver’s door, the vehicle
could roll.
> Press and hold the brake pedal > A\.
> Set the parking brake.
> To select the "P" selector lever position, press
the "P" button (2) on the selector lever
=> page 67, fig. 73.
Under certain conditions, such as driving in the
mountains, it may be helpful to switch to manual
mode temporarily to adapt to the driving condi-
tions manually > page 71.
On hills, activate the parking brake first and then
shift into the "P" position. This prevents too
much stress from being placed on the locking
mechanism.

ZA WARNING
— Do not press the accelerator pedal when
changing the selector lever position while
the vehicle is stationary and the engine is
running. This could result in a crash.
— To reduce the risk of an accident, never se-
lect the "R" or "P" positions while driving.
— 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.

@) 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 while the selector lever is in the
"N" position will damage the automatic

Towing.
— 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 i] indicator light turns on, stop the
vehicle at the next opportunity and let the
transmission cool > page 72.
G) Tips
For safety reasons, the parking brake only re-
leases automatically when the driver's door is
closed.
Launch Control Program
The Launch Control Program enables maximum
acceleration.
Requirement: the engine and transmission must
be at operating temperature and the steering
wheel must not be turned. The performance
mode* must be selected or dynamic mode must
be selected in Audi drive select.

ton briefly one time).
> Press the brake pedal firmly with your left foot
and hold it all the way down for at least 1 sec-
ond.
> Press the accelerator pedal down completely at
the same time until the engine reaches a high
RPM that remains constant and the message
appears Launch control program: activated ap-
pears.
> Remove your left foot from the brake.


ZA WARNING
— Always adapt your driving to the traffic flow.
— Only use Launch Control when road and traf-
fic conditions allow it and other drivers will

not be endangered or impacted by your driv-
ing and the vehicle's acceleration.
— Please note that the drive wheels can spin
and the vehicle can break away when ESC
sport mode is switched on, especially when
the road is slippery.
— Once the vehicle has started moving, press
the |[& OFF] button briefly to turn the ESC
sport mode off again.



G@) Tips
— The transmission temperature may increase
significantly after using the launch control
program. If that happens, the program may
not be available for a few minutes. It will be
available again after a cool-down period.
— When accelerating using the launch control
program, all vehicle parts are subject to
heavy loads. This can lead to increased wear.

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
