Driving dynamic

All wheel drive (quattro)
Applies to: vehicles with all wheel drive
The all-wheel drive system distributes the driving
power variably to the front and rear axle to im-
prove the driving characteristics. It works togeth-
er with selective wheel torque control, which can
activate when driving through curves
=> page 117.
The all-wheel drive system is designed for high
engine power. Your vehicle is exceptionally pow-
erful and has excellent driving characteristics
both under normal driving conditions and on
snow and ice. Always read and follow safety pre-
cautions > A\.
Quattro ultra
Applies to: vehicles with quattro ultra
If the driving situation does not require all wheel
drive, then the rear section of the drivetrain will
decouple and thus save fuel. The system con-
stantly determines and anticipates if all wheel
drive is needed. This allows the rear drivetrain to
recouple shortly before it is needed.

ZA\ WARNING
— Even in vehicles with all wheel drive, you
should adapt your driving style to the cur-
rent road and traffic conditions to reduce
the risk of an accident.
— The braking ability of your vehicle is limited
to the traction of the wheels. In this way, it
is not different from a two wheel drive vehi-
cle. Do not drive too fast because this in-
creases the risk of an accident.
— Note that on wet streets, the front wheels
can “hydroplane’” if driving at speeds that
are too high. Unlike front wheel drive
vehicles, the engine RPM does not increase
suddenly when the vehicle begins hydro-
planing. Adapt your speed to the road condi-
tions to reduce the risk of an accident.

116
Sport differential
Applies to: vehicles with sport differential
The sport differential distributes the drive power
to the rear axle based on the situation. The goal
is a high level of agility and ability to accelerate
on curves. The vehicle is very responsive to steer-
ing. The settings depend on the selected Audi
drive select* mode.

Electronic Stabilization
Control
Electronic Stabilization Control (ESC) supports
driver safety. It reduces the risk of slipping and
improves driving stability. ESC detects critical sit-
uations, such as if the vehicle is oversteering or
understeering, or if the wheels are spinning.
The brakes are applied or the engine torque is re-
duced in order to stabilize the vehicle.
The following stabilization functions are integrat-
ed into the ESC, among others:
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.
Anti-Slip Regulation (ASR)
ASR reduces drive power when the wheels begin
spinning and adapts the power to the road condi-
tions. This will increase the driving stability.
Electronic Differential Lock (EDL)
The EDL applies the brakes to wheels that are
slipping and transfers the drive power to the oth-
er wheels. 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 functioning correctly.
EDL will switch on again automatically when con-
ditions have returned to normal.
Selective wheel torque control
Selective wheel torque control is used when driv-
ing on curves. Braking is targeted toward the
wheels on the inside of the curve as needed. This
allows more precise driving in curves.
Power steering
The ESC can also support vehicle stability
through steering.

ZA 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 begin
acting to stabilize your vehicle, you should
immediately alter your speed to match the
road
and traffic conditions. Do not let the in-
creased safety provided tempt you into tak-
ing 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. There is still
a risk of accidents because the ESC and its
integrated systems cannot always prevent
collisions.
— Accelerate carefully when driving on
smooth, slippery surfaces such as ice and
snow. The drive wheels can spin even when
these control systems are installed and this
can affect driving stability and increase the
risk of a collision.
@) Tips
— The ABS and ASR only function correctly
when all four wheels have a similar wear
condition. Different tire sizes can lead toa
reduction in engine power.


— You may hear noises when the systems de-
scribed are working.
The So button (or #, depending on the model)
for controlling the ESC is located in the center
console, in front of the selector lever. The ESC is
automatically switched on when the ignition is
switched on.
Limiting ESC
In some situations, it may make sense to limit
the stabilizing function of the ESC so that the >

Wheels


ZA\ WARNING
Wheel bolts that are tightened or repaired in-
correctly can become loose and result in loss
of vehicle control, which increases the risk of
an accident. For the correct tightening specifi-
cation, see > page 291, Finishing.
— Always keep the wheel bolts and the threads
in the wheel hub clean and free of grease.
— Only use wheel bolts that fit the rim.
— Always have damaged rims repaired by an
authorized Audi dealer or authorized Audi
Service Facility. Never repair or disassemble
rims yourself, because this increases the risk
of an accident.
Loose wheel warning
Applies to: vehicles with loose wheel warning

Within the limits of the system, the loose wheel
warning in the instrument cluster warns you if
one or more wheels are loose.
Using the ABS sensors, the loose wheel warning
system compares the vibration characteristics of
the individual tires. If one or more wheels are
loose, it will be indicated in the instrument clus-
ter display with the & indicator light and a mes-
sage. If only one wheel is affected, the location
of that wheel will be indicated.

Check the wheel bolts on all wheels with the
wheel wrench (vehicle tool kit). Have the tighten-
ing specification checked as soon as possible with
a torque wrench. Drive carefully until then. For
the correct tightening specification, see
=> page 291, Finishing.

fi Loose wheel warning: malfunction! See
owner's manual
There is a system malfunction. Drive immediately
to an authorized Audi dealer or authorized Audi
Service Facility to have the malfunction repaired.

Z\ WARNING
Wheel bolts that are tightened incorrectly can
become loose and result in loss of vehicle con-
trol, which increases the risk of an accident.
— If a message appears, reduce your speed im-
mediately and avoid any hard steering or
braking maneuvers. Stop as soon as possible
and check the wheel bolts.
— Check your wheels for damage. Have the
damaged wheels checked and/or replaced
immediately by an authorized Audi dealer or
authorized Audi Service Facility.
— Under certain conditions (such as a sporty
driving style, winter conditions, or unpaved
roads), the message may be delayed.
— The driver is responsible for ensuring that
the wheels are attached correctly.
(i) Tips
— The loose wheel warning system can also
stop working when there is an ESC malfunc-
tion.

— Using snow chains may result in a system
malfunction.
Winter tires significantly improve the vehicle's
handling when driving in winter conditions. Be-
cause of their construction (width, compound,
tread pattern), summer tires provide less traction
on ice and snow.
> Use winter tires on all four wheels.
> Only use winter tires that are approved for your
vehicle.
> Please note that the maximum permitted
speed may be lower with winter tires > A\ in
General information on page 256. An author-
ized Audi dealer or authorized Audi Service Fa-
cility can inform you about the maximum per-
mitted speed for your tires.

rotor. Work carefully and have a second per-
son help you.
Unidirectional tires
A unidirectional tire profile is identified by arrows
on the tire sidewall that point in the running di-
rection. You must always maintain the specified
running direction. This is necessary to ensure the
tire's optimal performance in regard to adhesion,
running noise, and friction, and to reduce the risk
of
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.
> Reinstall the caps on the wheel bolts if necessa-
ry.
