Audi pre sense Preventative passenger
protection
Applies to: ve hicles with Audi pre sense
Pre sense can initiate steps to protect vehicle oc
cupants in certain dangerous situations. The
functions described are available depending on
veh icle equ ipment:
Pre sense basic*
The following functions can be triggered in cer
tain driving situations:
- Tightening of the safety belts (for examp le,
during emergency braking): the front safety
belts have reversib le belt pretensioners. If a
collision does not occur, the safety belts loosen
slightly and are ready to trigger aga in.
- Closing the w indows and the sunroof* (for ex
ample, when over- or understeering) : the win
dows and the sunroof* close until there is only
a small gap open .
Audi pre sense basic functions can be triggered at
speeds above 20 mph (30 km/h). Drive select: the deployment time is adapted in
Dynamic mode .
Pre sense front (vehicles with adaptive cruise
control*)
Pre sense front contains the functions of pre
sense basic . In addition, the likelihood of a rear
end collision with the vehicle ahead is also calcu
lated, within the limi ts of the system. If the risk
of a collision is detected, the following functions
can trigger:
- Braking guard
c> page 85
- Tensioning of the safety belts
- Closing the windows and the sunroof*
Pre sense rear (vehicles with side assist*)
Pre sense rear contains the functions of pre sense
bas ic. In addit ion, the lik el ihood of a rear-end
coll is ion from the vehicle behind is also calculat
ed, within the limits of the system. If the risk of a
collision is detected, the following functions can
trigger:
Audi pre sense
-Tensioning of the safety belts
- Closing the windows and the sunroof*
Pre sense plus*
Pre sense plus contains the functions of pre
sense front and pre sense rear .
Error message

Preventative passenger protection is not availa
ble. Drive to your authorized Audi dealer or au
thorized Audi Service Facility immediately to have
the malfunction corrected.
A WARNING
=
Pre sense cannot overcome natural phys ica l
laws . It is a system designed to assist and it
cannot prevent a collision . Do not let the in
creased safety provided tempt you into taking
risks. This could increase your risk of a colli
sion.
- The system can dep loy incorrectly .
- Please note that the sensors do not always
detect all objects . This increases the risk of
a collision.
- Pre sense does not react to people or ani
mals or objects that are crossing the vehi
cle's path or are difficu lt to detect
.:>page 79.
-Reflective objects such as guard ra ils or the
entrance to a tunnel, heavy rain and ice can
affect the function of the radar sensors and
the system's ability to detect a collision risk.
(D Note
The sensors can be displaced by impacts or
damage to the bumper, wheel housing and
un derbody. Pre sense can be impaired by this.
Have an authorized Audi dealer or authorized
Audi Service Facility check their function .
(D Tips
-Certain pre sense front functions switch off
when sport mode is switched off or when
driving in reverse. ..,.

Electronic Stabilization
Control (ESC)
Description
E SC helps to imp rove ro ad hold ing and vehicle
dynamics to help reduce the probab ility of skid
d ing and loss of veh icle control. It works only
when the engine is runn ing . ESC detects certain
d iffic ult dr iving situat io ns, including when the
ve hicl e is begin ning to spin (yaw) o ut of contro l
and h elps you to ge t the veh icle b ack u nde r con
trol by se lectively bra king the wheels, and/or re
ducing engine powe r and providing steering as
sistance to help hold the vehicle on the driver's
intended course. The indicator light
GI in the in
strument cluster blinks when ESC is tak ing action
t o he lp you contro l the vehicle.
ESC has lim itations. It is important to remembe r
that ESC cannot overcome the laws o f physics. It
will not a lways be able to help out under all con
d itions you may come up aga inst . For example,
ESC may not always be ab le to help you master
situations where there is a sudde n change in the
coeff ic ie nt of fr iction of the road surface. W hen
there is a se ction of dry roa d that is sudde nly cov
e red with w ater, slush o r sn ow , ESC c annot pe r
form the same way i t wou ld on the dry s urface. If
the vehicle hydrop lanes (rides on a cushion of wa
ter instead of t he road su rface), ESC w ill not be
ab le to he lp you stee r the veh icle because contact
with the pavement has been inte rru pted and the
ve hicle cannot be b raked or steered . Dur ing fast
cor nering, part icu la rly on w inding roads, ESC
can not always deal as effect ive ly w it h difficult
d riving situat ions than a t lowe r speeds .
Always ad just yo ur speed and driving sty le to
road, traffic and weath er cond itions . ESC canno t
over ride the vehicle's phys ical lim its, increase the
ava ilab le traction, o r keep a ve hicle on t he road if
roa d depa rture is a re su lt of driver in attention .
I nstead, ESC imp roves the possibili ty of keep ing
180
t h e veh icle unde r contro l and on t he road d uring
extreme mane uvers by using the driver's steer ing
i nputs to help keep the veh icle go ing in the in
tended direction. If you are traveling at a speed
that causes you to run off the road before ESC
can p rovide any assistance, you may not exper i
ence the be nefits of ESC.
ESC is switc hed on all the time. In certa in s itua
tions when you need less tract ion, you can sw itch
off ASR by press ing the button
[g] c:> page 181,
fig . 175 . Be sure to switc h ASR on aga in whe n
you no longer nee d less tract ion.
The following systems are integrated in the ESC:
Anti-lock braking system (ABS)
A BS prevents the w heels from locking w hen bra k
i ng . The veh icle can still be steered even dur ing
hard braking. App ly steady p ressure to the brake
pedal. Do not pump the pedal. A pulsing in the
brake peda l ind icates that the system is act ing to
stab ilize the veh icle.
Brake a ssist system
The brake assist system can decrease b raking dis
tance. It increases b raking powe r whe n the dr iver
presses the b rake peda l quickly in emergency sit
uat ions. You must press a nd hold the brake peda l
u nt il the dange rous situation is over . In vehicles
with adaptive cruise co ntrol*, the brake ass ist
syste m is more se nsitive if the distance detected
t o t he veh icle ah ead is too sm all. On vehicle s wi th
a ctiv ate d a nd fun ctioni ng nigh t vis ion assi st*, the
brake assis t sys tem can respond more sensit ively
i f there is a warning .
Anti-slip regulation (ASR )
ASR reduces e ngine powe r whe n the d rive whee ls
begin s pin nin g and ad apts the force to the ro ad
con ditions. This m akes i t easier to s tar t, a cce ler
ate and drive up incl ines .
Electronic differential lock (EDL)
E DL applies t he b rakes to a whee l th at s tarts
sp inning a nd transfers the dr ive power to the
othe r drivi ng whee ls . This fu nction is n ot a vail a-
b le at hig he r sp eeds . .,..

In extreme cases, EDL automatically switches off
to keep the brake on the braked wheel from over
heating. The vehicle is still working correctly. EDL
will switch on again automatically when condi
tions have returned to normal.
Steering recommendation
The ESC helps to stabilize the vehicle by changing
the steering torque .
I n vehicles with dynamic steering*, ESC also
helps to stabilize the steering in critical situa
tions.
Selective wheel torque control
Selective wheel torque control is used when driv
ing on curves. The front wheel on the inside of
the curve or both wheels on the inside of the
curve are braked selectively as needed. This al
lows more precise driving in curves.
Automatic post-collision braking system
The "Automatic post-collision brak ing system"
can help to reduce the risk of sliding and of other
coll isions after an accident.
If the airbag control
module detects a collision above a certain vehicle
speed, the vehicle is braked by the ESC.
The vehicle does not brake automatically if:
- the driver presses the accelerator pedal, or
- the braking force generated by the pressed
brake pedal is greater than the brak ing force
that would be initiated by the system, or
- the ESC, the brake system or the vehicle electri
cal system are not function ing .
Switching on /off
Intelligent Technology
A WARNING
-- The ESC and its integrated systems cannot
overcome the limits posed by natural physi
cal laws. This is especia lly important on slip
pery or wet roads. If the systems begin act
ing to stabilize your vehicle, you should im
mediately alter your speed to match the
road and traffic conditions. Do not let the
increased safety provided tempt you into
taking r isks. This cou ld increase your risk of
a collision .
- Please note the risk of a collision increases
when driving fast, especially through curves
and on slippery or wet roads, and when dr iv
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 dr ive wheels can spin
even when these control systems are instal
led and this can affect driving stability and
i n crease the risk of a collision .
(j) 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.
£SC turns on automatically when you start the engine.
Fig. 175 Center console: OFF~ button
The ESC is designed to function in levels. Depend
ing on the level that is se lected, the stabilization
function of the ESC is limited or switched off. The amount of stabilization control will differ de
pending on the level.
The following examples are unusual situations
where it may make sense to switch sport mode on in order to allow the wheels to spin:
- Rocking the vehicle to free it when it is stuck ..,.
181

Intelligent Technology
-Driving for an extended period of time on
salt-covered roads without using your
brakes can also affect braking efficiency .
Clean off accumulated salt coating from
brake discs and pads with a few careful
brake applications .
- If you damage the front spoiler, or if you in stall a different spoiler, be sure the air flow
to the front brakes is not obstructed. Other
wise the brake system could overheat reduc
ing the effectiveness of the entire brake sys
tem.
- Failure of one brake circuit will impair the
braking capability resulting in an increased
stopping distance. Avoid driving the vehicle
and have it towed to the nearest Audi dealer
or qualified workshop.
- Never let the vehicle roll to a stop with the
engine shut off.
- If the brake booster is not working, the
brake pedal must be pressed considerably
harder to make up for the lack of booster
assistance.
Electromechanical
steering, dynamic
steering
The electromechanical steering supports the
driver's steering movements.
Power steering adapts electronically based on
the vehicle speed .
Indicator lights and messages
• Do not drive vehicle: Steering defective
If this indicator light turns on and stays on and
this message appears, the power steering may
have failed .
Stop the vehicle in a safe location as soon as pos
sible. Do
not continue driving. See an authori zed
Audi dealer or authorized Audi Service Facility for
assistance.
'Jij Steering: System fault You can continue
driving
184
If the indicator light turns on and the message
appears, the steering may be more difficult to move or more sensitive than usual. The steering
wheel may also be at an angle when driving
straight.
Drive slowly to your authorized Audi dealer or au
thorized Audi Service Facility to have the mal
function corrected.
':r-ij Dynamic steering: Initializing
If the indicator l ight is blinking and this message
appears, dynamic steering* is being initialized.
The steering wheel will be easy to move after
starting the engine. Re-initialization might be
necessary if the steering wheel was moved hard
to the left and right while the veh icle was not
moving. The display turns off if the initialization
was successful.
(D Tips
- If the . or ':r-ij indicator light only stays on
for a short time, you may continue driving.
- The dynamic steering stability systems
opage 180 are not availab le in the event of
a system malfunction.
- For additional information on dynamic
steering, refer to
c> page 95.
All wheel drive (quattro)
Applies to: vehicles with all wheel drive
In all wheel drive, all four wheels are powered.
General information
In all wheel drive, the driving power is divided be
tween all four wheels. This happens automatical
ly depending on your driving behavior as well as
the current road conditions. Refer to
c> page 180,
Electronic Stabilization Control (£SC).
A center differential distributes the driving power
variably to the front and rear axle. It works to
gether with selective wheel torque control, which
activates when driving through curves
<=> page 181 . With the sport differential*, power
distribution to the rear wheels is variable and can
be adjusted with drive select
q page 95 . .,..

Wheels
-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.
-Only use tires that are more than 6 years old when abso
lutely necessary and drive
carefully when doing so.
-Do not use run-flat tires on your vehicle. Using them when
not permitted can lead to ve
hicle damage or accidents.
-If you install wheel covers on the vehicle, make sure they al
low enough air circulation to
cool the brake system. If they
do not, this could increase the
risk of an accident.

Tire wear/damage
Fig. 191 Tire profile : treadwear indica
tor
Tire wear
Check the tires regularly for wear.
-Inflation pressure that is too low or high can increase tire wear
considerably.
-Driving quickly through curves, rapid acceleration and heavy
braking increase tire wear.
-Have an authorized Audi dealer
or authorized Audi Service Facili
ty check the wheel alignment if
there is unusual wear.
-Have the wheels rebalanced if an imbalance is causing noticeable
vibration in the steering wheel. If you do not, the tires and other
vehicle components could wear
more quickly.
Treadwear indicator
The original tires on your vehicle have 1/16 inch (1.6 mm) high
"wear indicators" ¢fig.
191 ...

The specified tire pressure is the last tire pres
sure that was stored
¢ page 2 3 7 .
Note that the tire p ressure also depends on the
temperature of the t ire . Every 10 °C increase in
tire temperature results in the tire pressure in
creasing by approximate ly 0 .1 bar. The tire pres
sure increases as the eng ine becomes warmer
while driving.
A WARNING
