-Never turn off the engine before the vehicle
has come to a complete stop.
- The brake booster and power steering only
work when the engine is running. If the en­ gine is off, you have to use more force when
steering or braking. Because you cannot
steer and brake as you usually would, this
could lead to accidents and serious injuries.
@ Note
Avoid high engine speed, full throttle, 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 immediately . This re­
duces unnecessary emissions.
(D Tips
-Some noise after starting the engine is nor­
mal and is no cause for concern.
- If you leave the vehicle with the ignition
switched on, the ignition will switch off af­
ter a certain amount of time. Make sure that
electrical equipment such as the exterior
lights are switched off.
Stopping the engine
.,. Bring the vehicle to a full stop.
.,. Move the selector lever into the P position .
... Press the I START ENGINE STOPI button.
Emergency off function*
If it is absolutely necessary, the engine can also
be turned off while driving at speeds starting at
4 mph (7 km/h). To switch the engine off, press
the
I START ENGINE STOPI button twice in a row
br iefly or press and hold for longer than two sec­
onds.
A WARNING
- Never turn off the engine before the vehicle has come to a complete stop.
Driving
-Please note that the brake booster and pow­
er steering only work when the engine is
running. When the engine off, you must use
more force to steer or brake the vehicle. Be­
cause the usual steering and braking capa­
bility is not available, the risk of accidents or
. . . . mJunes increases.
-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.
- After the engine has been switched off, the
radiator fan can continue to run for up to 10
minutes
-even with the ignition switched
off. It can also switch on again after some
time if the coolant temperature rises as the result of heat buildup or if the engine is al­
ready warm and the engine compartment is
also heated by the sun's rays.
@ 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.

vehicle's features.
Engine and automatic transmission
Depending on the mode, the engine and auto­
matic transmission respond more quickly or in a
more balanced manner to accelerator pedal
movements.
Suspension control (Audi magnetic ride)*
The suspension control uses sensors to record in­
format ion regarding steering movements, brak­
i ng and acceleration operations by the driver, as
well as information about the road surface, driv­
i ng speed, and load. W ith dr ive se lect, you can
adjust the suspension control to sporty (dynam­
ic ), comfortable (comfort) or balanced (auto).
Steering
The power steering adapts . Indirect steering that
moves eas ily as in comfort mode is espec ially
su ited to long drives on a highway . The dynamic
mode provides sporty, direct steering.

spoiler deployed can impair handling charac­
teristics, making the vehicle harder to con­
trol.

spoiler must be free of ice, snow and leaves .
Intellig ent T echn olo gy
Energy management
Your vehicle is equipped with an intelligent ener­
gy management system for distributing electrici ­
ty. This significantly improves the starting ability
and increases the vehicle battery life.
(D Tips
- If you drive short distances frequent ly, the
vehicle battery may not charge enough
wh ile driving. As a result, convenience func­
tions for electr ical equipment may be tem­
pera rily unavailable .
- The vehicle battery w ill gradually drain if
the vehicle is not driven for long per iods of
t ime, or if electr ical equ ipment is used
when the engine is not runn ing. To ensure
that the veh icle can still be started, the
elect rical eq uipment w ill be red uced or
sw itched
off.
Information about data
recorded by vehicle
control modules
Your vehicle is not equipped with a crash data re­
corder . This dev ice is installed by some veh icle
manufacturers to record data about crashes so
t h at it can be ana lyzed later. Crash data reco rd ­
ers are also called " Event Data Recorders (EDR)".
In some legal jurisdictions, it is not permitted to
access or down load data recorded by pre-instal­
led crash data recorders in orde r to evaluate a
crash without clear consent of the vehicle owner.
Your vehicle is not equ ipped w ith a crash data re­
corder . However it does contain a variety of e lec­
tronic control modules for various vehicle sys­
tems such as engine function, exha ust treatment
or airbags and safety belts.
T hese electronic contro l modu les record veh icle
data du ring normal driv ing fo r diagnosis and re­
pair purposes. The record ing capability of the
electronic control modules is limited to data only
-no sound is recorded . If the contro l module de ­
tects a system ma lfunction or other change in
status, a very limited amount of data is recorded
for an extremely small period of time. Data that
