Electronic stabilization
control (ESC)
Description
Electronic Stabilization Control (ESC) supports
driver safety.
It reduces the risk of slipping and
improves driving stability. ESC detects critical sit­
uations such as the vehicle oversteering and un­
dersteering or the wheels are spinning. The vehi­
cle is stabilized by applying the brakes or reduc ­
ing engine torque. When ESC engages, the
G1 in­
dicator light blinks in the instrument cluster.
The following systems are integrated in the ESC:
Anti-lock braking system (ABS)
ABS prevents the wheels from locking when brak­
ing. The vehicle can still be steered even during
hard braking. Apply steady pressure to the brake
pedal. Do not pump the pedal. A pulsing in the
brake pedal indicates that the system is acting to
stabilize the vehicle .
Brake assist system
The brake assist system can decrease braking dis­
tance. It increases braking power when the driver
presses the brake pedal quickly in emergency sit­
uations . You must press and hold the brake pedal
until the dangerous situation is over .
Anti-slip regulation (ASR)
ASR reduces engine power when the drive wheels
begin spinning and adapts the force to the road
conditions. This makes it easier to start, acceler­
ate and drive up hills .
Electronic differential lock (EDL)
EDL applies the brakes to a wheel that starts
spinning and transfers the drive power to the
other driving wheels. This function is not availa­
ble at higher speeds.
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.
88 Steering
recommendation
The ESC helps to stabilize the vehicle by changing
the steering torque.
Selective wheel torque control
Selective wheel torque control is used when driv­
ing on curves. The front whee l on the inside of
the curve or both wheels on the inside of the
cu rve are braked selectively as needed. This al­
lows more precise driving in curves. The applica ­
ble system may not activate when driving in wet
or snowy conditions.
A WARNING
- The ESC and its integrated systems cannot
overcome the limits imposed by natural physical laws. This is especially important
on slippery or wet roads. If the systems be­
gin acting to stabilize your vehicle, you
should immediately alter your speed to
match the road and traffic conditions. Do
not let the increased safety provided tempt
you into taking risks. This could 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 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.
(j) Tips
-The ABS and ASR only function correctly
when all four wheels have a similar wear
condition. Different tire sizes can lead to a
reduction in engine power.
- You may hear noises when the systems de­
scribed are working.

-Never use the screw driver hex head to
tighten wheel bolts, since the bolts cannot
attain the necessary tightening torque if you
use the hex head, potentially causing an ac­
cident .
- The factory-supplied jack is intended only
for your veh icle model. Under no circum ­
stances shou ld it be used to lift heavy
veh icles or othe r loads; you risk injuring
yourself.
- Never start the engine when the vehicle is
raised, which co uld cause an a ccident.
- Support the vehicle securely with a ppropri­
ate stands if wo rk is to be pe rformed under­
nea th the vehicle; otherwise, there is a po­
tential risk fo r injury.
- Never use the ja ck supp lied with your Aud i
on ano ther veh icle, p articularly on a heavier
one. The jack is only s uitab le for use on the
veh icle it came with.

Emergency assistance
_& WARNING
You or your passengers could be injured while
changing a wheel if you do not follow these
safety precautions :
- If you have a flat tire, move a safe distance
off the road. Turn off the engine, turn the
emergency flashers on and use other warn­
ing devices to alert other motorists.
- Make sure that passengers wait in a safe
place away from the vehicle and well away
from the road and traffic.
- To help prevent the vehicle from moving
suddenly and possibly slipp ing off the jack,
always fully set the parking brake and block
the wheel diagona lly opposite the wheel be­
ing changed . When one front wheel is lifted
off the ground, placing the Automatic
Transmission in P (Park) will
not prevent the
vehicle from moving.
- Before you change a wheel, be sure the
ground is level and firm. If necessary, use a
sturdy board under the jack.
- Always store the vehicle tool kit, the jack
and the replaced tire in the luggage com­
partment

The wheel bolts must be clean and loosen/tight ­
en easily . Check the contact surfaces for the
wheel and hub. Contam inants on these surfaces
must be removed before installing the wheel.
A WARNING
Never use the hex socket in the screwdriver
handle to tighten the wheel bolts. Using the
hex socket will not achieve the required tight­
ening torque, which increases the risk of an
accident.
(D Note
When removing or installing the wheel, the

r otor* and damage the rotor. Work carefully
and have a second person help you .
(D Tips
- When mounting tires with unidirectional
tread design make sure the tread pattern is
pointed the right way
Q page 286.
-The wheel bolts should be clean and easy to
turn. Check for dirt and corrosion on the
mating surfaces of both the wheel and the
hub. Remove all dirt from these surfaces be­
fore remounting the whee l.
Unidirectional tires
A unidirectional tire profi le is identified by arrows
that point in the runn ing direction on the tire
s idewall. You must always adhere to the speci­
fied running direction. This is necessary ensure
the tire's optimum performance in regard to ad­
hesion , running noise, friction and hydroplaning.
To benefit fully from the advantages of the uni­
directional tire design, you should replace faulty
tires as soon as possible and restore the correct
running direction on all of the tires.
Finishing
