available when ASR is switched
off (sport
mode) or when driving in reverse.
- The Audi pre sense functions may not be
available if there is a ma lfunction in the ESC
system or the airbag control module.
- The Audi pre sense front/plus functions are
not available if there is a malfunction in the
adaptive cruise control* system

Electronic Stabilization
Control (ESC)
Description
ESC helps to improve road holding and vehicle
dynamics to help reduce the probability of skid­
ding and loss of vehicle control. It works only
when the engine is running. ESC detects certain
difficult dr iving situations, including when the
veh icle is beginn ing to spin (yaw) out of contro l
and helps you to get the vehicle back under con­
trol by se lectively braking the wheels, and/or re­
ducing engine power 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 taking action
to help you control the vehicle.
ESC has limitations. It is important to remember
that ESC cannot overcome the laws of physics. It
will not always be able to help out under all con­
ditions you may come up against . For example,
ESC may not always be able to help you master
situations where there is a sudden change in the
coefficient of friction of the road surface. When
there is a section of dry road that is suddenly cov­
ered with water, slush o r snow , ESC cannot per­
form the same way it wou ld on the dry surface. If
the vehicle hydrop lanes (rides on a cushion of wa­
ter instead of the road surface), ESC wi ll not be
able to he lp you steer the vehicle because contact
with the pavement has been interrupted and the
vehicle cannot be braked or steered. During fast cornering, part icularly on w inding roads, ESC
cannot always deal as effective ly w ith difficult
driving situat ions than at lower speeds . When
towing a trailer, ESC is not able to help you re­
ga in control as it would if you were not towing a
trai ler.
Always adjust your speed and driving sty le to
road, traffic and weather conditions. ESC cannot
override the vehicle's physical limits, increase the
190
available traction, or keep a vehicle on the road if
road departure is a result of driver inattention.
Instead, ESC improves the possib ility of keeping
the vehicle under control and on the road during extreme maneuvers by using the driver's steering
inputs to help keep the vehicle going in the in­
tended direction . If you are traveling at a speed
that causes you to run off the road before ESC
can provide any assistance, you may not exper i­
ence the benefits of ESC.
ESC is switched on all the time. In certa in s itua­
tions when you need less traction, you can sw itch
off ASR by press ing the button above
~ page 192, fig. 186 the selector lever. Be sure
to switch ASR on again when you no longer need
l ess traction.
The following systems are integrated in the ESC:
Anti-lock braking system (ABS)
ABS prevents the wheels from locking up when
braking. The vehicle can still be steered even dur ­
i ng 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 help ­
i ng you to brake the vehicle.
Brake assist system
The brake assist system can decrease braking dis­
tance. It increases braking power when the dr iver
presses the brake pedal quickly in emergency sit­
uations. You must press and hold the brake pedal
u nt il the situation is over. In vehicles with adap ­
tive cruise control*, the brake assist system is
more sensitive if the d ista nee detected to the ve­
hicle ahead is too sma ll.
Anti-slip regulation (ASR)
ASR reduces engine powe r when the dr ive wheels
begin to spin and adapts the force to the road
cond itions. This makes it easier to start, acceler­
ate and drive up hills.
Electronic differential lock (EDL)
The EDL brakes wheels that are spinning and
transfers the drive power to the other wheels.
This function is not available at higher speeds .

Sport mode on
The following situations are exceptions where it
may be useful to switch on sport mode to allow
the wheels to spin:
- Rocking the vehicle to free it when it is stuck
- Driving in deep snow or on loose ground
- Dr iving with snow chains

A WARNING
You should only switch sport mode on if your
dr iv ing abilities and road condit ions perm it .
- The stabilization function is limited when
sport mode is sw itched on. The driving
wheels cou ld spin and the vehicle could
swerve, espec ially on s lick o r sli ppery road
s urfac es.
Sport mode cannot be sw itched on if t he
cruise cont rol system* or the adaptive cru ise
cont rol* is switched on.
Braking
What affects braking efficiency?
New brake pads
During the first 250 miles (400 km), new brake
pads do not possess the ir full braking effect, they
have to be "broken in" first ¢
.1:,.. The break-in pe­
riod can be considerably longe r fo r vehicles with
192
ceramic brake rotors*. You can compensate for
this slightly reduced braking power by push ing
harder on the brake pedal. Avoid heavy braking
lo ads during the break-in period.
Operating conditions and driving habits
The brakes on today's automobiles are still sub ­
j ect to wear, depending large ly on operating con­
ditions and driving habits¢,& . On vehicles that
are either driven mostly in stop-and-go city traf­
fic or are driven hard, the brake pads should be
checked by your authorized Audi dealer more of ­
ten than specified in the
Warranty & Mainte­
nance booklet .
Failure to have your brake pads
inspected can result in reduced brake perform­
ance.
On steep slopes, you should use the brak ing ef­
fect of the engine. T his way, you prevent unnec­
essary wea r on the brake system. If you mus t use
your brakes, do not hold the brakes down contin-
u ously. Pump th e brakes at intervals. ..,.
