Requirement: the driver's door must be closed,
the driver's safety belt must be latched and the
parking brake must be set.
.,. To start driving and release the parking brake
automatically, press the accelerator pedal as
usual.
In addition to releasing the parking brake auto­
matically, other convenience and safety functions
are available when you start driving
¢page 74,
Starting to drive.
Preventing the automatic parking brake
release
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

your risk of a collision.
- Please note the risk of a co llision increases
when driving fast, especially through curves
and on slippery or wet roads, and when driv­
ing too close to objects ahead. The ESC and
its integrated systems cannot always pre­
vent collisions -there is still a risk of acci­
dents!
- Press the accelerator pedal carefully when
accelerating on even, slippery surfaces such
as ice and snow. The drive wheels can spin

even when these control systems are instal­
led and this can affect driving stability and increase the risk of a collision.
(D Tips
- ABS and ASR only function correctly when
all four wheels are equipped with identical
tires. Different tire sizes can lead to a reduc­ tion in engine power.
- You may hear noises when the systems de­
scribed are working.
ESC turns on automatically when you start the engine.

The following examples are unusual situations
where it may make sense to switch sport mode
on in order to allow the wheels to spin:

Sport mode on
- Rocking the vehicle to free it when it is stuck
- Driving in deep snow or on loose ground
- Driving with snow chains
Applies to: RS models: the ESC is designed to
function in levels. Depending on the level that is
selected, the stabil izat ion function of the ESC is
limited or switched off. The amount of stabiliza­

necessary. This causes the brakes to over­
heat and increases braking distance and
causes wear.
- Before driving downhi ll a long distance on a
steep hill, decrease your speed and select a l ower gear. This makes use of the engine
braking effect and relieves the brakes. If
you need to brake additionally, brake in in­
tervals and not continuously .
(D Tips
-If the brake booster is not working, you
must press the brake pedal with much more
force than normal.
- If you retrofit your vehicle with a front spoil­
er, wheel covers or s imilar items, make sure
that the a ir flow to the front wheels is not
i nterrupted. Otherw ise the brake system

By using all wheel d rive, yo ur vehicle has good
forward motion with standard t ires in winter con­
ditions. However, in winter we recommend using
wint er or all season t ires on all four wheels, be­
cause this will improve the braking effect.
Snow chains
If

_& WARNING
-Also, in vehicles with a ll wheel drive, adapt
yo ur dr iv ing style to the cu rrent road and
traff ic conditions . Do not let the increased
sa fety provided tempt you into taking risks ,
because th is increases the r isk of an acci­
dent .
- The braking ability of your veh icle is limited
to the tract ion of t he wheels . In this way, it
is not diffe rent from a two whee l dr ive vehi ­
cle. Do not be tempted to accelerate to a
hig h speed when t he road is slippe ry, be­
ca use this increases the risk of a n accide nt .
- Note that on wet streets , the fro nt wheels
can "hyd roplan e" if d riving at speeds that
are too hig h. Unlike front whee l drive
vehicles, t he eng ine does not rev highe r su d­
den ly when the vehicle begins hydroplaning .
For this reason, adapt your speed to the

These facilities have the proper
know ledge and are eq uipped with
the required too ls and rep lace­
ment parts.
1>- New tires do not yet have the
optim um gripping properties.
Drive carefully and at moderate
speeds for the first 35 0 m iles

vehicle with a tire/rim combina­
tion that is different from what
was installed at the factory, con­
sult with an authorized Audi
dealer or authorized Audi Service Facility before making a pur­
chase
i=:> &, .
Because the spare tire* is differ­
ent from the regular tires instal­
led on the vehicle (such as winter
tires or wide tires), only use the spare tire* temporarily in case of
emergency and drive carefully
while it is in use. It should be re­
placed with a regular tire as soon
as possible.
Applies to: vehicles with all wheel drive: all four wheels must be
equipped with tires that are the
same brand and have the same construction and tread pattern so
that the drive system is not dam­ aged by different wheel speeds .
~ For this reason, in case of emer-
-~ gency, only use a spare tire* that

regular tires.
&_ WARNING
-
-Do not use steel rims that are
17 inches or larger. Other­
wise, damage to the vehicle
and an accident could result.
-Only use tire/rim combina­ tions and suitable wheel bolts
that have been approved by
Audi. Otherwise, damage to
the vehicle and an accident
could result.
-For technical reasons, it is not possible to use tires from oth­
er vehicles -in some cases,
you cannot even use tires from the same vehicle model.
-Make sure that the tires you select have enough clearance
to the vehicle. Replacement
tires should not be chosen
simply based on the nominal
size, because tires with a dif­
ferent construction can differ
greatly even if they are the
same size. If there is not
enough clearance, the tires or
the vehicle can be damaged
and this can reduce driving
safety and increase the risk of
an accident.

Tire pressure monitoring
system
ill General notes
Each tire, including the spare (if provided),
should be checked monthly when cold and inflat­
ed to the inflation pressure recommended by the
vehicle manufacturer on the vehicle placard or
tire inflation pressure label. (If your vehicle has
tires of a different size than the size indicated on
the vehicle placard or tire inflation pressure la­
bel, you should determine the proper tire infla­
tion pressure for those tires).
As an added safety feature, your vehicle has been
equipped with a tire pressure monitoring system
(TPMS) that illuminates a low tire pressure tell­
tale when one or more of your tires is significant­
ly under-inflated. Accordingly, when the low tire
pressure telltale illuminates, you should stop and
check your tires as soon as possible, and inflate
them to the proper pressure. Driving on a signifi­
cantly under-inflated tire causes the tire to over­
heat and can lead to tire failure. Under-inflation
also reduces fuel efficiency and tire tread life,
and may affect the vehicle's handling and stop-
ping ability.
.,.

a co .... N
" N .... 0 00 \,;J ' Please note that the TPMS is not a substitute for
proper tire maintenance, and it is the driver's re­
sponsibility to maintain correct tire pressure,
even if under-inflation has not reached the level
to trigger illumination of the TPMS low tire pres­
sure telltale .
Your vehicle has also been equipped with a TPMS malfunction indicator to indicate when the sys­
tem is not operating properly. The TPMS mal­
function indicator is combined with the low tire pressure telltale. When the system detects a
malfunction, the telltale will flash for approxi­
mately one minute and then remain continuously
illuminated. This sequence will continue upon
subsequent vehicle start-ups as long as the mal­
function exists.
When the malfunction indicator is illuminated,
the system may not be able to detect or signal
low tire pressure as intended. TPMS malfunctions
may occur for a variety of reasons, including the
installation of replacement or alternate tires or
wheels on the vehicle that prevent the TPMS
from functioning properly . Always check the
TPMS malfunction telltale after replacing one or
more tires or wheels on your vehicle to ensure
that the replacement or alternate tires and
wheels allow the TPMS to continue to function
properly.
Description
Applies to: vehicles with tire pressure monitor ing system
The tire pressure monitoring system monitors
the pressure in the four tires when driving.
T he system uses sensors that measure the tem ­
perature and pressure in the tires . The data is
sent from these sensors to the control module by radio frequency.
T he Tire Pressure Monitoring System shows the
current pressures and temperatures of the tires
in the Infotainment system
¢page 226. It also
compares the current tire pressures with the
stored tire pressures and gives a warning in the
driver information system if the tire pressure is
different from what is
stored ¢ page 226 .
Wheels
The system does not detect if the stored tire
pressures match the recommended tire pres­
sures. You must store the tire pressures again
¢ page 226:
- every time the tire pressures change, for exam­
ple when the load in the vehicle changes,
- after replacing a tire, or
- if wheels with new wheel sensors are used.
_& WARNING
- The tire pressure monitoring system assists
the driver in monitoring tire pressures. The
driver is responsible for having the tires in­
flated to the correct pressure.
- Do not change the tire pressure when the
temperature of the tire is extremely high.
This could result in serious damage to the
tire and even cause the tire to burst, in­
creasing the risk of an accident.
- A tire with low pressure flexes more. This heats the tire up too much. This could cause
the tread to separate and even cause the
tire to burst, increasing the risk of an acci­
dent.
- The tire pressure monitoring system does not warn about damage or defects in the
tire construction that could cause the tire to
burst, for example. Inspect your tires regu­
larly.
(D Tips
- If tires are replaced, the sensors/valves do
not need to be removed or replaced . Just re­
placed the valve stem and, if necessary, the
valve and the wheel electronics. If you have questions, see an authorized Audi dealer or
authorized Audi Service Facility.
- An incorrect display or a malfunction in the
tire pressure monitoring system can occur
after using the tire mobility kit. Have the
sensors replaced by an authorized Audi
dealer or authori zed Audi Service Facility.

FCC regulations in the United States and the
Industry Canada regulations, see
