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.

Safety belts
General notes
Always wear safety belts!
Wearing safety belts correctly saves lives!
This chapter explains why safety belts are neces­
sary, how they work and how to adjust and wear
them correctly. "' Read all the information that follows and heed
all of the instructions and WARNINGS.
A WARNING
Not wearing safety belts or wearing them im­
properly increases the risk of serious personal
injury and death .
- Safety belts are the single most effective
means available to reduce the risk of serious
injury and death in automobile accidents.
For your protection and that of your passen­
gers, always correctly wear safety belts
when the veh icle is moving.
- Pregnant women, injured, or physically im­
paired persons must also use safety belts.
Like all vehicle occupants, they are more
likely to be seriously injured if they do not
wear safety belts. The best way to protect a
fetus is to protect the mother -throughout
the entire pregnancy.
Number of seats
Your Audi TT Coupe has two seating positions in
the front and two height-limited seating posi­
tions in the rear . Each seating position has a safe ­
ty belt. The rear seat area in your Audi TT Coupe
does not have enough room for passengers of all
sizes. For reasons of safety , no person taller than
4 ft 9 in (S7 in/1.4S m) should ever r ide in the
r ear seat area.
A WARNING
Not wearing safety belts or wearing them im­
properly increases the risk of serious personal
injury and death .
Safety belts
- Never strap more than one person, includ­
ing small children, into any belt. It is espe­
cially dangerous to place a safety belt over
a
child sitting on your lap .
- Never let more people ride in the vehicle
than there are safety belts available.
- Be sure everyone riding in the vehicle is
properly restrained with a separate safety
belt or child restraint .
- Persons taller than 4
ft 9 in (57 in/1.45 m)
as well as children in booster seats who are
too close to the rear window and roof can
suffer severe head and neck injuries when
the rear lid is closed or in a crash.
- The minimum clearance between the pas­ senger's heads and the rear window must
never -under any circumstances -be less
that lin (2.5 cm) when the passengers sit
fu lly upright.
- Always make sure that rea r seat passengers
cannot be struck when the rear lid is closed.
4 Safety belt warning light
Your vehicle has a warning system for the driver
and front seat passenger to remind you about the importance of buckling up.
Fi g. 150 Safety belt warning light in the instrument clus­
ter -enlarged
Before driving off , always:
"' Fasten your safety belt and make sure you wear
it properly.
"' Make sure that your passengers also buckl e up
and properly wear their safety belts.
"' Protect children with a child restraint system
appropriate for the size and age.

New tires or wheels
Audi recommends having all work
on tires or wheels performed by
an authorized Audi dealer or au­
thorized Audi Service Facility.
These facilities have the proper knowledge and are equipped with
the required tools and replace­ ment parts .
.,.. New tires do not yet have the
optimum gripping properties.
Dr ive carefully and at moderate
speeds for the first 350 miles (500 km) with new tires.
.,.. Use tires of the same construc­
tion, size (rolling circumference)
and as close to the same tread
pattern as possible on all four
wheels .
.,.. Do not replace tires individually.
At least replace both tires on the same axle at the same time.

should be replaced with a regular
tire as soon as possible.
On
all wheel drive vehicles, all
four wheels must be equipped
with tires that are the same brand and have the same construction
and tread pattern so that the
drive system is not damaged by
different tire speeds . For this rea­

8,_ WARNING , -
-Only use tire/rim combina-
tions and suitable wheel bolts
that have been approved by
Audi. Otherwise, damage to
the vehicle and an accident
could result.
-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 six years old when abso­
lutely necessary and drive
carefully when doing so.
Wheels
-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.

ty precautions in ¢ page 267,
Tires and vehicle load limits.
-The tire must flex more if the tire pressure is too low or if
the vehicle speed or load are
too high. This heats the tire up
too much. This increases the risk of an accident because it
can cause the tire to burst and
result in loss of vehicle con­
trol.
