Electronic stabilization
control (ESC)
Description
The E lectronic Stabilization Contro l (ESC) reinfor­
ces driver safety. It reduces the risk of slipping
and improves driving stability. ESC detects criti ­
cal s ituations such as the vehicle oversteering
and understeering or the wheels a re spinning.
The vehicle is stabilized by applying the brakes or
reducing engine torque. Once the ESC is activat­
ed, the indicator light
DJ blinks in the instru­
ment cluster.
The fol low ing systems a re integrated in the ESC:
Anti-lock braking system (ABS)
ABS prevents the wheels from locking when brak­
i ng. 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 ind icates that the system is acting to
stabilize the vehicle .
Brake assist system
The brake assist system can decrease braking d is­
tance . It increases braking power when the driver
presses the brake pedal quickly in emergency s it­
uations. You must press and hold the brake pedal
unti l the dangerous sit uation is ove r. In vehicles
with adaptive cruise control *, the brake assist
system is more sensit ive if the distance detected
to the vehicle ahead is too small.
Anti-slip regulation (ASR)
ASR reduces engine power when the drive whee ls
begin spinning and adapts the force to the road
conditions. This makes it easier to start, acceler­
ate and drive up inclines.
Intelligent Technology
Electronic differential lock (EDL)
The EDL brakes whee ls that are spinning and
trans fers the drive power to the other drive wheel
or whee ls if the vehicle is equipped with all wheel
drive*). This function is not available 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 correct ly. 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 .
Selective wheel torque control
Selective wheel torque control is used when dr iv­
i ng on curves. The front wheel on the inside of
the curve o r 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 "Automat ic post -collision braking system"
can help to reduce the ris k of sliding and of other
collisions after an accident. If the airbag control
module detects a collision above a certain vehicle
speed, the vehicle is braked by the ESC.
T he 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 electr i­
cal system are not funct ion ing .
A WARNING
-The ESC and its integrated systems cannot
overcome the limits posed by natural phys i­
cal laws. This is especially important on slip­
pery or wet roads .
If the systems begin act­
ing to stabilize your vehicle, you should im-
mediately a lter your speed to match the ..,.

Luggage compartment
lid emergency release
The luggage compartment can be opened from
the inside in an emergency.
F ig. 1 73 Sect ion of t he luggage compartment: access to

The trunk escape handle inside th e rear lid is
made of fluorescent material to glow in the dark.
A WARNING
The trunk escape handle is to be used only in
an eme rgency .
(D Tips
The emergency re lease lever should never be
used as a handle for closing the rear lid.
General information
.,. Park the veh icle as far as possib le from moving
traffic in the event of a flat tire. In the event of
a flat tire, park the vehicle on a leve l surface . It
you are on a steep incline, be especially careful.
.,. Set the parking brake .
.,. Place the selector lever in the P pos ition .
.,. Swi tc h the eme rgency flashers on .
.,. Put on a reflective vest, if ava ila b le .
.,. Set up the war ning triang le, if available.

A WARNING
Pay attention to the steps above. They are for
your p rotection and the for the safety of other
drivers.
A WARNING
"'
Imp roper use of the vehicle jack can cause se-
rious pe rsonal injuries.
- Never use the screw driver hex head to
tighten wheel bolts, since the bolts cannot
attain the necessa ry tight ening torque if yo u
use the hex head, p oten tially cau sing an ac­
cide nt.
- The factory-s upplied jack is intended only
for your veh icle mode l. Unde r no c ircum­
s tances shou ld i t b e used t o lift heavy
veh icles or othe r loads; you risk inj uring
yourse lf.
- Never start the engi ne when t he vehicle is
raised, which could ca use a n accident .
- Suppor t the vehicle secu rely w it h a ppropri­
ate stands if work is to be performed under ­
neath the vehicle; otherw ise, there is a po ­
tential risk for injury .
- Never use the jac k supplied with your Aud i
on another vehicle, part icu lar ly on a heavier
one. The jack is on ly suitable for use on the
veh icle it came with.
(D Tips
-Some of the onboard it ems listed above are
provided on certai n models only or are op­
t ional extras.
- Before stor ing the jack*, make sure it is
wound back down as far as it wi ll go.

Emergency assistance
_& WARNING
Always read and follow all WARNINGS and in­
formation
c:> & in Raising the vehicle on
page 244
and c:> page 245.
After changing a wheel
A wheel change is not complete without the do­
ing the following .
.. Always store the vehicle tool kit, the jack* and
the replaced tire in the luggage compartment
c:> page 136 .
.. Check the tire pressure on the spare wheel im­
med iate ly after mounting it .
.. As soon as possible, have the
tightening tor­
ques
on all wheel bolts checked with a torque
wrench. The correct tightening torque is 90 ft
lb
(120 Nm) .
.. Have the flat tire
replaced as soon as possible.
@ Tips
-If you notice that the wheel bolts are cor­
roded and difficult to turn while changing a
tire, they should be replaced before you
check the tightening torque.
- Drive at reduced speed until you have the
tightening torques checked.
- After changing a wheel, the tire pressure in
all four tires must be checked/corrected and
the tire pressure mon itoring indicator must
be stored in the MMI
c:> page 234.
