Short-term memory and long-term memory
The short-term memory collects driving informa-
tion from the time the ignition is switched on un-
til it is switched off. If you continue driving within
two hours after switching the ignition off, the
new values will be included when calculating the
current trip information.
Unlike the short-term memory, the long-term
memory is not erased automatically. You can se-
lect the time period for evaluating trip informa-
tion yourself.
Average consumption
The current consumption can be shown using a
bar graph. The average consumption stored in >

Driving dynamic

Depending on the setting, the drive power at the
rear axle will be distributed with the sport differ-
ential* to be more sporty or moderate
=>page 115.
In RS models, the sport differential is adjusted
using a separate menu item.
Steering
The power steering will adapt. Light steering is
suitable for long trips on highways or smooth
driving around curves, for example.
Suspension
The suspension adjusts to be tighter or more
comfort-oriented when it comes to compensat-
ing for uneven spots on the road.
Based on the selected setting, the air suspen-
sion* will adjust the ground clearance and the ac-
tive roll stabilization* will provide various de-
grees of compensation for vehicle movements.
Engine sound
The engine sound adapts and can be subtle to
sporty. In the automatic setting, the engine
sound depends on the selected driving program.
quattro with sport differential
Applies to: RS models
Depending on the setting, the drive power at the
rear axle will be distributed with the sport differ-
ential* to be more sporty or moderate
=>page 115.
ESC
Applies to: RS models
The ESC sport mode can be activated. Also refer
to the important information regarding driving
with ESC limited > page 116.
Suspension
CET aN mer) t cd
Applies to: vehicles with suspension control
The adaptive dampers are an electronically-con-
trolled damping system. The firmness of the sus-
pension will adapt to the driving conditions and
the driving situation. The settings depend on the
selected Audi drive select* mode.
112
Air suspension
Applies to: vehicles with air suspension
The air suspension is an electronically-controlled
suspension and leveling system. The firmness of
the suspension will adapt to the driving condi-
tions and the driving situation. The system balan-
ces out changes in load. The vehicle level will also
adapt gradually to the vehicle speed in order to
reduce the wind resistance at high speeds and in-
crease the ground clearance at low speeds. The
settings depend on the selected Audi drive se-
lect* mode.
Displaying the vehicle level
> Applies to MMI: Select on the home screen: VE-
HICLE > Audi drive select.
The filled-in boxes represent the current vehicle
level. The more boxes that are filled in, the high-
er the ground clearance. The box that corre-
sponds with the current vehicle level will flash
while the vehicle is lifting or lowering. The target
level is highlighted in color.
Raising the vehicle
> Applies to MMI: Select on the home screen: VE-
HICLE > Audi drive select.
> Press Raise to reach the highest vehicle level
and thus the maximum ground clearance.
> Press Lower to lower the vehicle down again.
The Audi drive select* mode will be changed if
necessary when the vehicle is raised.
The vehicle will lower at speeds of approximately
20 mph (30 km/h) and below. This function may
only be used temporarily when increased ground
clearance is necessary. It is not intended for long
drives.
@) Note
— Also refer to the information about ground
clearance > page 113.
— When transporting the vehicle on a road
carrier, rail carrier, ship carrier, or other car-
rier, it may only be secured at the running
surfaces of the tires (circumference). Secur-
ing the vehicle at the axle components, sus-
pension struts, or towing eyes is not

comparable to a vehicle without rear axle steer-
ing. Drive carefully to an authorized Audi dealer
or authorized Audi Service Facility to have the
malfunction corrected.
BS Steering lock: malfunction! Please contact
Service
There is a malfunction in the electronic steering
lock. Drive immediately to an authorized Audi
dealer or authorized Audi Service Facility to have
the malfunction repaired.

IX WARNING
Do not tow your vehicle if there is a malfunc-
tion in the electronic steering lock because
this increases the risk of an accident.
@ Tips
—If there is a malfunction, the steering wheel
may be crooked when driving straight.
—Ifthe A or indicator light only stays on
for a short time, you may continue driving.

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 116.
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\.

Z\ 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.
By Tamer!
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.
Messages
it} Sport differential: malfunction! Please con-
tact Service
Drive immediately to an authorized Audi dealer
or authorized Audi Service Facility to have the
malfunction repaired.
it} Sport differential: temperature too high.
Please adapt driving style
The transmission temperature has increased sig-
nificantly due to the sporty driving manner. Drive
in a less sporty manner until the temperature re-
turns to the normal range and the indicator light
switches of.

ZA\ WARNING
Contact an authorized Audi dealer or author-
ized Audi Service Facility if the sport differen-
tial is faulty or malfunctioning. The repair
must be performed by trained personnel us-
ing the correct oil in order to ensure safety.

Driving dynamic

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 oversteering and understeering of
the vehicle, the drive wheels spinning, or the risk
of the vehicle tipping.
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.
116
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.
— As the vehicle load increases, especially the
roof load, the vehicle's center of gravity also
increases along with the risk of the vehicle
tipping. To reduce the risk of an accident, al-
ways adapt your driving style to the current
conditions and avoid sudden driving maneu-
vers.
G) 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
