A WARNING
-- Read and follow the warnings in
¢ page 233, Working in the engine com­
partment
before opening the hood and
checking the brake fluid level.
- If the brake system indicator light does not
turn off or it turns on while driving, the
brake fluid level in the reservoir is too low,
and this increases the risk of an accident .
Stop the vehicle and do not continue driv­
ing. See an authorized Audi dealer or au­
thorized 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.

Driving
keep your foot on the brake in all selector
lever positions (except P) when the engine is
running. Otherwise, this increases the risk
of an accident.
- Do not inadvertently press the accelerator
pedal when the vehicle is stopped if a gear is
engaged. Otherwise the vehicle will start to
move immediately, 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 leave your vehicle with the engine
running while in gear.
If you must leave
your vehicle when the engine is running, set
the parking brake and move the selector lev­
er to the "P" position.
- To decrease the risk of an accident, these­
lector lever must be in the P position and
the parking brake must be set before open­
ing the hood and working on a running en­
gine. Always read and follow the applicable
warnings¢ page 233, Working in the en­
gine compartment .
(D Note
Never let the vehicle roll downhill with engine
off and the selector lever in the "N" position,
because this could damage the automatic
transmission and catalytic converter .
{D) Tips
- Drive select: sporty shifting characteristics
can be selected using the
Dynamic driving
mode . The Infotainment display shows Sas
the selector lever position instead of D.
- If you accidentally select "N" while driving,
take your foot off the accelerator pedal im­
mediately and wait for the engine to slow
down to idle before selecting "D" or "S".
- If there is a power failure, the selector lever
will not move out of the "P" position. The
emergency release can be used if this hap­
pens. Left-hand drive
vehicles¢ page 69.

Selector lever lock
The selector lever lock prevents you from select­
ing a gear accidentally, causing the vehicle to
roll .
Fig. 71 Selector lever lock
To release the selector lever lock:
.., Switch the ignition on.
....
.., Press the brake pedal while pressing the inter-
lock button.
Automatic shift lock (ASL)
The selector lever is locked in the "P" and "N" po­
sitions when the ignition is switched on. You
must press the brake pedal to select another po­
sition. You must also press the interlock button if
you are moving from the "P" position. The follow­
ing message appears in the display when these­
lector lever is in the "P" or
"N" position to remind
the driver:
To select a gear, please press brake pedal and press lock button on selector lever
The automatic shift lock only functions when the
vehicle is stationary or at speeds below 1 mph
(2 km/h). At higher speeds, the lock is automati­
cally deactivated in the "N" position.
The selector lever is not locked when shifting
quickly through "N", for example from "R" to "D".
This makes it possible to free the vehicle when it
is stuck by "rocking" it. The selector lever lock en­
gages if the lever stays in the "N" position longer
than approximately two seconds when the brake
pedal is not pressed.
Iii>

Driving
When parking on a level surface, simply place the
selector lever in the "P" position. On inclines, ac­
tivate the parking brake first and then move the
selector lever to the "P " position
c> page 61 . This
prevents the locking mechanism from being
loaded too heavily and will make it easier to
move the selector lever out of the "P" position.
A WARNING
- The vehicle can roll even when the engine is
switched off .
- Unintended vehicle movement can lead to
serious injuries.
- Never leave your vehicle with the engine
running while in gear . If you must leave
your vehicle when the engine is running, set
the parking brake and move the selector lev­
er to the P position.
- Power is still transferred 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 when the en­
gine is running and the selector lever is in
the "D" , "S" or "R" position or "tiptronic"
mode is selected.
- 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
"ti ptron i c" .
- 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 substantially re­
duces braking performance, increases brak­
ing distance or causes complete failure of
the brake system.
- If you must stop on an incline, always hold
the vehicle in place with the foot brake or
66
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
overload. The
ml indicator light turns on
and a message appears
c> page 68 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 engag­
ed. The selector lever must be firmly in the
P position and locked in place and the park­
ing brake must be set
c> page 233. Other­
wise, the vehicle could begin moving when
increasing the engine speed, even with the
parking brake set.
@ 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
ml or. indicator light turns on, stop the
vehicle at the next opportunity and let the
transmission cool
c> page 68.
- Allowing the vehicle to roll when the engine
is stopped will damage the S tronic trans­
mission because it is not lubricated
c> page 285, Towing with a tow truck .
(D Tips
For safety reasons, the parking brake is re­
leased automatically only when the driver's
safety belt is fastened.

Emissions control
systems
Catal ytic conve rt er
The vehicle may on ly be driven with unleaded
gasoline, otherwise the catalyt ic converter will be
destroyed.
Never drive until the tank is completely empty.
The irregular supply of f uel that results from that
can cause engine m isfires. Uncombusted fuel will
enter the exhaust system, wh ich can cause over­
heat ing and damage to the catalyt ic converter .
A WARNING
The temperature of the exhaust system is
high, both when d riving and after stopping
the engine.
-
- Never touch the exhaust tail pipes once they
have become ho t. This could result in bu rns.
- Do not park your vehicle ove r flammable
materials such as g rass or leaves because
the high temperat ure of the em iss ions con­
trol system co uld s tart a fire.
- Do not apply underbody p rotectant in the
exha ust system area, because this inc reases
the risk of fi re.
