Audi drive select
Introduction
Applies to: vehicles with Audi drive select
Drive select makes it possible to experience dif-
ferent types of vehicle characteristics in one vehi-
cle. With different driving modes, the driver can
switch the setting, for example from sporty to
comfortable. This allows you to adjust the set-
tings to your personal preferences. This makes it
possible to combine settings such as a sporty
drivetrain setting with comfortable steering.
Selecting an Audi drive select mode
Applies to: vehicles with Audi drive select
The size button is located above the selector lever
in the center console.
> Press the left or right arrow key until the de-
sired mode appears in the MMI. Or:
> Applies to MMI: Select on the home screen: VE-
HICLE > Audi drive select.
You can change the driving mode when the vehi-
cle is stationary or while driving. If traffic per-
mits, briefly remove your foot from the accelera-
tor pedal after changing modes so that the mode
you have selected will be activated for the drive
system.
The following modes may be available depending
on the equipment:
offroad - Provides assistance when driving off-
road. The vehicle will be raised to the second-
highest level using the air suspension*. The ESC
will be restricted and the hill descent assist* will
be activated. The vehicle will exit this mode after
the ignition is switched off.
allroad - Provides balanced vehicle handling. The
vehicle will be raised to the second-highest level
using the air suspension*.
comfort - Provides a comfort-oriented vehicle
setup and is suited for long drives on highways.
auto - Provides an overall comfortable yet dy-
namic driving feel and is suited for everyday use.
dynamic - Gives the driver a sporty driving feel
and is suited to a sporty driving style. The “S”
driving program is selected.
Individual - Provides the option for personalized
vehicle settings. Press ¥ to configure the mode
=> page 111, Individual settings.

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

4M8012721BF
Driving dynamic

permitted because the pressure in the air
suspension struts can change during trans-
port. The vehicle might not be secured suffi-
ciently if this happens.
Active roll stabilization
Applies to: vehicles with active roll stabilization
The active roll stabilization enhances the air sus-
pension with an electromechanically-controlled
suspension system. It influences targeted rolling
movements when driving on curves and during
fast swerving maneuvers. The settings depend on
the selected Audi drive select* mode.
Ground clearance
The vehicle height and clearance can be influ-
enced by the following factors:
— Change in temperature
— Change in load
— Change to the Audi drive select* mode
— Lifting and lowering via the air suspension*
— Lower the rear* of the vehicle

ZA WARNING
To reduce the risk of injury, make sure no one
gets pinched when the vehicle level is chang-
ing, for example when cleaning the under-
body or the wheel housings.
@) Note
Always make sure there is enough clearance
above and below the vehicle. This is especially
important for entrances with height restric-
tions, for example, before driving into under-
ground garages. You could also scrape the
ground when driving over the edges of curbs
or on steep ramps, which could damage your
vehicle.

Steering
Electromechanical steering supports the driver's
steering movements by electronically adapting
the power steering depending on the vehicle
speed. The settings depend on the selected Audi
drive select* mode.
Progressive steering
Applies to: vehicles with progressive steering
The driving dynamic and driving stability are in-
creased by the steering ratio based on the steer-
ing wheel angle. The steering is very direct when
the steering wheel angle is sharp, and indirect
when the angle is low. This enables comfortable
maneuvering and a precise steering response at
higher driving speeds.
All-wheel steering
Applies to: vehicles with all-wheel steering
Additional steering ability at the rear axle im-
proves the driving dynamic and stability. At low
speeds, the rear wheels are steered in the oppo-
site direction from the front wheels to reduce the
turning radius. At high speeds, steering the rear
wheels in the same direction as the front wheels
114
improves the vehicle response and driving stabili-
ty.
a Steering: malfunction! Please stop vehicle
The power steering may have failed. Adapt your
driving style immediately to compensate for the
fact that it may be more difficult to turn the
steering wheel, and stop your vehicle in a safe lo-
cation as soon as possible. Do not continue driv-
ing. See an authorized Audi dealer or authorized
Audi Service Facility for assistance.
a Steering: malfunction! Please stop vehicle.
Pay attention to distance at side
The rear axle steering may have failed. More
space on the road may be needed at the side of
the vehicle, and the turning radius may be much
larger. Slow down immediately, and stop your ve-
hicle as soon as possible in a safe location with
enough space at the sides of the vehicle. Do not
continue driving. See an authorized Audi dealer
or authorized Audi Service Facility for assistance.
BS Steering: malfunction! Please stop vehicle

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

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 can spin, for example to rock a vehicle to
free it when it is stuck or to drive with snow
chains. The ESC can also be limited to provide
more sporty driving characteristics with fewer
stabilizing corrective actions.
—To limit the ESC, press the 0 button briefly.
The B indicator light will turn on.
— To completely reactivate the ESC stabilization
function, press the button again. The indicator
light turns off.
Depending on the Audi drive select mode that is
selected, one of the following ESC modes will be
selected automatically:
— sport - this mode is designed for driving ona
level surface. It is used in all Audi drive select
modes except offroad.
— offroad - this mode is suited for driving offroad
and is designed for uneven terrain or loose
ground. If you select the offroad Audi drive se-
lect mode, the offroad ESC mode will be auto-
matically used.
Switching off ESC
For a more active control of the vehicle where the
stabilizing functions of the ESC cannot intervene,
the ESC can be switched off.
— To switch off the ESC, press and hold the Sor
button for more than three seconds. The B
and Ea indicator lights turn on.
— To completely reactivate the ESC stabilization
function, press the button again. The indicator
lights turn off.

ZA WARNING
— When the ESC is switched off or limited,
there will be no vehicle stabilization or it will
be limited. The driving wheels could spin
and the vehicle could swerve, especially on
slick or slippery road surfaces. When there is


a heavy vehicle load and sudden driving ma-
neuvers, it may not be possible to prevent
the vehicle from tipping under certain cir-
cumstances, which increases the risk of an
accident.
— Because of the increased risk of an accident,
only drive with the ESC switched off or Limit-
ed when it is necessary. Reactivate the ESC
as soon as possible.
@ Tips
— If you select the Audi drive select* offroad
mode, hill descent assist will switch on.
— If the ESC is limited, switched off, or mal-
functioning, systems with an automatic
braking intervention function may not be
fully available.
— If malfunctions occur in other systems or
certain driver assist systems are active, the
ESC must be switched on by the system. The
ESC
may switch on automatically and can-
not be operated with the button.
B is / B © Stabilization control (ESC/
ABS): malfunction! See owner's manual


There is a malfunction in the ABS or EDL. This al-
so causes the ESC to malfunction. The brakes still
function with their normal power, but ABS is not
active.
Drive to an authorized Audi dealer or authorized
Audi Service Facility immediately to have the
malfunction corrected.
Other indicator lights
iff blinks while driving, the ESC is actively reg-
ulating. Operating noises may occur. If the indi-
cator light stays on, the ESC has been switched
off due to system needs. The indicator light turns
off when the system is fully functional.

Trailer towing

Trailer towing
Driving with a trailer
er else)
Your vehicle is primarily intended for transport-
ing people and luggage. However, if you drive
with a trailer, follow the technical requirements,
the operation and driving tips, and the legal reg-
ulations.
Driving with a trailer affects the vehicle's energy
usage, performance, and wear. It also requires
higher concentration from the driver.

ZA\ WARNING
Do not transport any people in a trailer due to
the risk of fatal injury.
Technical requirements
Trailer hitch

Only use a trailer hitch with a removable ball
hitch mount and ball hitch. The trailer hitch must
be permitted for the vehicle, the trailer and the
permitted total weight of the trailer being
pulled. Above all, it must be securely and safely
attached to the vehicle trailer.
Never mount a trailer hitch on the bumper. The
trailer hitch must be mounted in a way that does
not impair the function of the bumper. Do not
make any changes to the exhaust system and the
brake system.
Check regularly if the trailer hitch is securely
mounted. Always follow the instructions given by
the trailer hitch manufacturer.
Trailer brakes
If the trailer has its own brake system, then fol-
low the manufacturer specifications. However,
the brake system on the trailer must never be
connected to the vehicle brake system.
Engine cooling system
Driving with a trailer means a higher load on the
engine and the cooling system. The cooling sys-
tem must be designed for additional load and
contain enough coolant > @.
118

ZA\ WARNING
— Never mount a "weight-distributing" or
"load-balancing" trailer coupler as the trailer
hitch. The vehicle was not designed for
these types of trailer hitches. The trailer
hitch can malfunction and the trailer can
break off from the vehicle.
— If the trailer is equipped with electronic
brakes, these brakes cannot be activated by
a factory-installed control system, which in-
creases the risk of an accident.
—To reduce the risk of injury, always remove
the ball hitch mount if no trailer is mount-
ed
@) Note
Longer inclines cannot be driven without a
suitable cooling system, especially if the out-
side temperatures are high. Otherwise, this
increases the risk of engine damage.
ey emia aCe
Towing capacity

The permitted towing capacity must not be ex-
ceeded under any circumstances > page 314.
You can drive up larger inclines if you are not us-
ing the maximum towing capacity.
The specified towing weights only apply at eleva-
tions up to 3,200 feet (1,000 m) above sea level.
As the elevation increases, the engine power de-
creases due to the decreasing air pressure. This
reduces the hill climbing ability and towing ca-
pacity. For every additional 3,200 feet (1,000 m),
the maximum permitted towing weight must be
reduced by approximately 10%. The permitted
towing weight is the combined weight of the
(loaded) vehicle and the (loaded) trailer.
Tongue weight
The maximum permitted tongue weight of the
trailer drawbar on the trailer hitch ball head must
not be exceeded.
For driving safety, Audi recommends always us-
ing
the maximum permitted tongue weight, but
do not exceed this weight. Distributing the cargo >
