parking brake
Fig . 94 Center conso le: park ing brake
Your vehicle is equipped with an e lectromechani ­
cal parking brake@~
fig. 94. The parking brake
is designed to prevent the vehicle from rolling
un intentionally and replaces the hand brake.
Setting/manually releasing the parking
brake
.. Pull the<®> switch to set the parking brake. The
LED in the switch illuminates. The -(USA
models)/ . (Canada models) indicator light al­
so turns on in the instrument cluster display .
.. To release the parking brake manually, press
the brake or acce lerator pedal while the igni­
t ion is switched on and press the© switch at
the same time. The LED in the button and the
indicator light in the display turn off.
Releasing the parking brake automatically
Requirement: the driver's door must be closed,
the dr iver's safety belt must be latched and the
parking brake must be set.
.,. To start driving and release the park ing brake
automatically, press the acce lerator peda l as
usual.
In addition to releasing the parking brake auto­ mat ically, other convenience and safety funct ions
are available when you start driving~
page 82,
Starting from a stop.
Preventing the automatic parking brake
release
The vehicle could begin rolling unintentionally,
depending on the hill or if towing a trailer.
Driving
.. To prevent the parking brake from releasing au­
tomatically, pull and hold the(®) switch and press the accelerator peda l. The parking brake
remains set and prevents the vehicle from roll­
ing backward .
.,. You can release the<®> switch again once you
are sure that you are giving enough driving
force to the wheels by press ing 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 ho lding the© switch wh ile 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 sim ilar 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 veh icle.
.,. Pull the(®) switch to set the parking brake.
.,. Select the P selector lever position .
.,. Tu rn the engine off~_& .
.,. Turn the steering w heel when parking o n in­
clines so that the wheels w ill roll into the curb
if the vehicle starts moving.
& WARNING
-
-Do not press the acce lerator peda l 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 accide nt.
- Eme rgency braking should only be used in
an emergency, when the normal brake pedal
has failed or the brake pedal is obstructed . ..,.
81

Driving
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
held with the brake pedal. The parking brake
eliminates the tendency to creep when a se­
lector lever position is engaged. As soon as
you press the accelerator pedal, the parking brake releases automatically and your vehicle
starts to move
c> page 82.
(D} Tips
-Occasional noises when the parking brake is
set and released are normal and are not a
cause for concern.
- The parking brake goes through a self-test
cycle at regular intervals when the vehicle is
stopped. Any noises associated with this are normal.
82
- If there is a power failure, the parking brake
will not set if it is released, and it will not release if it is set ¢&. . See an authorized
Audi dealer or authorized Audi Service Fa­ cility for assistance .
Starting from a stop
Various convenience and safety functions may be
available when the vehicle begins driving, de­
pending on vehicle equipment .
Starting on hills with the parking brake set
Requirement: the driver 's door must be closed
and the driver's safety belt must be fastened.
.,. To start driving comfortably when on a hill, set
the parking brake and begin driving as usual.
The braking force of the parking brake does not
release automatically until the wheels build up
enough driving force.
Starting on hills with hill hold assist
Hill hold assist makes it easier to start on hills.
Requirement: the driver's door must be closed
and the engine must be running.
.,. To activate hill hold assist, press and hold the
brake pedal for several seconds. The vehicle
must be in an uphill direction of travel.
After releasing the brake pedal, the braking pow­
er is maintained for a brief moment
c> &. to pre ­
vent the vehicle from rolling back when starting.
During this time, you can easily begin to move
your vehicle.
&_ WARNING
A ppl ies to: ve hicles with hill hold assist
- If you do not begin driving immediately or
the engine stalls after releasing the brake
pedal, your vehicle may begin to roll back­
ward. Press the brake pedal or set the park­
ing brake immediately .
- The intelligen t technology of hill hold assist
cannot overcome the limitations imposed by
natural physical laws. The increased comfort
offered by hill hold assist should not cause
you to take safety risks .

0 co .... N ,..... N .... 0 0 :c ' -To reduce the risk of an accident, never se­
lect the R or P posit ions while driving.
- Power is sti ll transmitted to the wheels
when the engine is running at idle. To pre­

When driv ing with a trailer, activate the trailer
mode of the air suspension. Switch the air sus ­
pension trailer mode on when you are towing a
trailer. This will limit the regulation by the air
suspension while driving. Select in the MMI:

Coolant temperature
The coolant temperature gauge¢ page 9 must
be observed carefully . The coolant temperature
can increase if you drive on long inclines in a low
gear at high engine speeds. Reduce your speed
i mmed iately if the LEDs in the top part of the dis­
p lay turn on.
For more information about indicator lights, re­
fer to. ¢
page 20.
A WARNING
Anyone not properly restrained in a moving
vehicle is at a much greater risk in an acci­
de nt. Never let anyone ride in you r car who is
not properly wearing the restraints p rovided
by Audi.
Trailer mode notes
Important to know -
Your veh
icle handles differently when tow ing a
tra iler because of the additional weight and d if ­
ferent weight distr ibut ion. Safety, performance
and economy will greatly depend on how careful­
ly yo u load you r trailer and operate your rig.
Before you actually tow your trailer, practice
turning, stopp ing and back ing up in a n area away
from traffic. Keep practicing until you have be­
come completely fami liar with the way your vehi­
cle-trailer comb inat io n behaves and responds.
Backing up is difficult and requires pract ice.
Backing up with a trailer gene rally requires steer­
ing action opposite to tha t when backing up your
ve hicl e without a trailer .
Maintain a greater d istance between your vehicle
and the one in front of you . You w ill need more
Trailer mode
room to stop . To compensate for the trailer, you
will need a larger than normal turning radius .
When passing, remember that you cannot accel­
erate as fast as you normally wo uld because of
the added load. Make sure you have enough room
to pass. After passing, allow p lenty of room for
your trailer before changing lanes again .
Avo id jerky starts, sharp turns or rapid lane
changes.
(D Tips
- Do not tow a trailer during the break-in peri­
od of your veh icle.
-If you tow a trailer, your Audi may requ ire
more frequent maintenance due to the ex­
tra load ¢
page 336.
Parking on a slope
Do not park on a slope with a trailer. If it cannot
be avoided, do so only after doing the following:
When parking:
" Apply the foot brake .
" Have someone place chocks under both the ve­
hicle and the trailer wheels.
"W ith chocks in place, slowly release the brakes
until the wheel chocks absorb the load.
" Tur n the whee ls towards the curb.
" App ly the parking brake.
" Select the P selector lever position.
When restarting after parking:
"App ly the foot brake.
" Start the engine .
"S elect the D selector lever position .
" Release the parking brake and slowly pull out
and away from the wheel chocks.
" Stop and have someone retrieve the wheel
chocks.
(D Tips
If you move the selector lever of the automat­
i c transmission to P before applying the park­
in g brake and before blocking the wheels, you
may have to use more force later to move the
lever out of the P posit ion.

A WARNING
Always pay attention to traffic when adapt ive
cruise control is switched on and braking
guard is active . As the dr iver, you are still re­
sponsible for starting and for maintaining
speed and d istance to other objects. Braking
guard is used to assist you . The driver must
always take action to avoid a collision . The
driver is always responsib le for brak ing at the
co rrect time .
- For safety reasons, do not use adapt ive
cruise co ntro l when driv ing on ro ads w ith
many curves, when the road su rface is in
poor condit ion and/or in bad weather (s uch
as ice, fog, grave l, heavy rain and hydrop la n­
ing). Using the system under these condi­
t ions increases the risk of an accident.
- Switch adaptive cruise contro l off tempora­
rily when driving in turning lanes, on ex­
pressway exits or in construction zones. This
prevents the vehicle from accelerating to
the stored speed when in these situations .
- The adapt ive cru ise control system will not
brake by itself if you put your foot on the ac­
celerator pedal. Doing so can overr ide the
speed and distance regulation .
- When approaching stat ionary objects such
as stopped traffic, adapt ive cru ise control
will not respo nd and braking gua rd will have
l imited func tion .
- The adapt ive cru ise control system and
bra king g uard do not react to people, ani­
mals, objects crossing the road or oncom ing
objects.
- T he function of the radar sensors can be af­
fec ted by reflec tive objects s uch as guard
rai ls, the ent rance to a tunnel, heavy rain or
ice.
& WARNING
- Improper use of adaptive cruise control can cause collisions, other accidents and serious
persona l injury.
- Never let the comfort and convenience that
adaptive cruise cont rol and braking guard
A ss ist
offe r dist ract you from the need to be alert
to traffic cond itions and the need to remain
in full control of your vehicle at all times,
- Always remember that the adaptive cruise
control and braking guard have limits -they
will not slow the vehicle down or maintain
the set distance when you dr ive towa rds an
obstacle or something on or near the road
that is not moving, s uch as vehicles stopped
in a t raff ic jam, a stalled or disab led vehicle.
If r eg istered by the radar sensors, vehicles
or obsta cles that are not moving ca n trigger
a co llision wa rning and if confirmed by the
video came ra, an acute co llision wa rning .
- Never fo llow a vehicle so closely that you
cannot stop your vehicle safely . The adap­
tive cruise contro l cannot slow or brake the
veh icle safely w hen you follow another vehi­
cle too closely. A lways remember that the
automatic braking function cannot bring the
veh icle to a sudde n or emergency stop u n­
der these conditions .
- To prevent unintended operat ion , always
sw itch ACC off when it is not being used .
(D Note
The sensors can be d isplaced by impacts or
damage to the bumper, wheel housing and
underbody. That could affect the adaptive
cruise contro l system and braking gua rd .
