A WARNING
To reduce the risk of poisoning, never allow
the engine to run in confined spaces.
(D Note
Avoid high engine speed, full th rottle, and
heavy engine load if the engine has not
reached operating temperature yet . You could
damage the engine.
@ For the sake of the environment
Do not let the engine run while parked to
warm up. Begin driving immediate ly. This re­
duces unnecessary emissions.
(D Tips
- Some noise after starting the engine is nor­
ma l and is no cause for concern.
- If you leave the veh icle w ith the ignition
switched on, the ignition w ill switch off af ­
ter a certain amount of time . Make sure that
electrical equipment such as the exterior
lights are switched off .

I START ENGINE STOPI button and also press the
brake pedal.
A WARNING
- Never turn off the engine before the vehicle
has come to a complete stop. The full func­
tion of the brake booster and the power
steering is not guaranteed. You may need to
use more force when braking or steering.
Because you cannot brake and steer as you
usually would, this could lead to accidents
and serious injuries.
- Always take the key with you whenever you
leave your vehicle. Otherwise, the engine
could be started or electrical equipment
such as the power windows could be operat­
ed. This can lead to serious injury.
- For safety reasons, always park the vehicle
with the selector lever in the P position.
Otherwise, there is the risk that the vehicle
could roll unintentionally.
@ Note
If the engine has been under heavy load for
an extended period of time, heat builds up in
the engine compartment after the engine is
switched off and there is a risk of damaging
the engine. For this reason, let the engine run
at idle for approximately two minutes before
shutting it off.
(D Tips
For up to 10 minutes after stopping the en­
gine, the radiator fan may turn on again auto­
matically or it may continue to run (even if
the ignition is switched off) for the following
reasons:
- The coolant temperature is increasing due
to trapped heat.
- If the engine is warm and the engine com­
partment also heats up from strong sun­
light.
- Applies to: vehicles with particulate filter:
The emissions control system is heated
through the regeneration process, even if
the engine has not reached its operating
temperature yet.

The vehicle could begin rolling unintentionally,
depending on the hill or if towing a trailer.
.,. To prevent the parking brake from releasing au­
tomatically, pull and hold
the(®) switch and
press the accelerator pedal. The parking brake
remains set and prevents the vehicle from roll­
ing backward.
.,. You can release the C®l switch again once you
are sure that you are giving enough driving
force to the wheels by pressing the accelerator pedal.
Emergency braking function
You can use the emergency braking function in an
emergency situation, or if the standard brake op­
eration malfunctions or is disabled.
.,. Pull and hold the®) switch.
.,. As soon as you release the (®) switch or acceler-
ate, the braking stops.
Pulling and holding the
C®) switch while driving
the vehicle activates the emergency braking func­
tion. The vehicle is braked at all four wheels by
activating the hydraulic brake system. The brak­ ing effect is similar to heavy
braking¢&_ .
To reduce the risk of activating the emergency
braking by mistake, a warning tone (buzzer)
sounds when
the®> switch is pulled. Emergency
braking stops as soon as
the®) switch is released
or the accelerator pedal is pressed.
Parking
.,. Press the brake pedal to stop the vehicle.
Driving
.,. Pull the®> switch to set the parking brake .
.,. Place the selector lever in the P position.
.,. Turn the engine off¢&_ .
.,. Turn the steering wheel when parking on in­
clines so that the wheels will roll into the curb
if the vehicle starts moving.
A WARNING
-
- Do not press the accelerator pedal inadver­
tently if a gear is selected when the vehicle
is stationary and the engine is running. Oth­
erwise, the vehicle will start to move imme­
diately and this could result in an accident.
- Emergency braking should only be used in
an emergency, when the normal brake pedal
has failed or the brake pedal is obstructed.
During emergency braking, your vehicle will
brake similar to heavy braking. ESC and the
associated components (ABS, ASR, EDL)
cannot overcome the laws of physics . In cor­
ners and when road or weather conditions
are bad, a full brake application can cause
the vehicle to skid or the rear end to swerve,
which
increases the risk of an accident.
- If the power supply fails , you cannot set the
parking brake if it is released . In this case,
park the vehicle on level ground and secure
it by placing the selector lever in the P posi­
tion. See an authorized Audi dealer or au­
thorized Audi Service Facility for assistance.
- Always take the vehicle key with you when
leaving your vehicle, even for a short period
of time. This applies particularly when chil­
dren remain in the vehicle. Otherwise chil­
dren could start the engine, release the
parking brake or operate electrical equip­
ment such as power windows, which in­
creases the risk of an accident .
- No one should remain in the vehicle when it
is locked - especially children . Locked doors
make it more difficult for emergency work­
ers to get into the vehicle, which puts lives
at risk.
(D Tips
When stopping at a traffic signal or stopping
in city traffic, you can set the parking brake
manually . The vehicle does not have to be
73

Drivin g
held with the br ake pedal. T he parking brake
eliminates the tendency to creep when a se­
lector lever pos ition is engaged . As soon as
you press the accelerator pedal, the park ing
brake releases automat ically and your vehicle
starts to move
¢ page 74 .
(D Tips
- Occasiona l noises when the parking brake is
set and re leased are normal and are not a
cause for concern .
- The park ing brake goes through a se lf-test
cycle at regular intervals when the veh icle is
stopped . Any noises associated w ith this are
no rmal.
- If there is a power fa ilure, the parking brake
will not set if it is released, and it will not r elease if it is
set¢ &. See an authorized
A udi dealer or authori zed Audi Servi ce Fa­
cility for ass istance.

Automatic transmission
Introduction
The au tomatic transmissio n is controlled elec­
t ronically. The transmission shifts up or down au ­
tomat ic al ly depen ding on which dr ive p rogr am is
selected .
When a
moderate driving sty le is used, the
t ransm iss ion selects the mos t econom ica l dr iv ing
mode. The tra nsmission upshi fts at a lowe r RPM
and downs hifts a t a higher RPM to improve fue l
efficiency.
The transmission sw itc hes to a sporty mode after
a kick- down o r when the dr iver uses a
s porty
dri ving style
characterized by quick acce lerato r
pedal movements, heavy acceleration, frequent
c h anges in sp eed and t raveling at the maximum
speed .
I f desired, t he driver can also selec t the gears
manually (tipt ronic mode ) ¢ page 78.

this increases the risk of an accident.
- 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 b rake in all selector
lever positions (except P) when the engine is
r u nning. Otherwise, this inc reases the risk
of an acc ident.
- Do not inadvertently p ress the accelerator
pedal when the vehicle is stopped if a gea r is
engaged. O therwise the ve hicle will start to
move immed iate ly, even if the parking brake
is set . This could result in a crash.
- To decrease the r is k of an accident, these­
lecto r lever mus t be in the P pos ition and
the parking brake must be set before open ­
ing the hood and working on a running en­
g ine. A lways read and follow the applicable
