Driving
Driving through water
If you must drive through water, follow these in-
structions:
— Check the stability of the ground, the current,
and the water depth. If the ground is unstable,
there is a strong current, or there are waves,
the water must only reach up to the lower edge
of the body at the most.
— Deactivate the Start/Stop system.
— Drive carefully and no faster than at walking
speeds to prevent the front of the vehicle from
creating waves, because they could splash
above the lower edge of the body. Oncoming
vehicles could also create waves.
— Do not stop the vehicle while in the water.
— Drive in reverse.
— Do not turn the engine off.
After driving through water, press the brake
pedal carefully to dry the brakes so that the
full braking effect will be restored.
Vehicle components such as the engine, drive
system, suspension, or electrical system can
be severely damaged by driving through wa-
Lele
If possible, avoid driving through salt water
because it increases the risk of corrosion. Use
fresh water to clean any vehicle components
that come into contact with salt water.

Driving dynamic
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.
Syed)
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.
t3] All-wheel drive: malfunction! You can con-
tinue driving. Please contact Service
Drive immediately to an authorized Audi dealer
or authorized Audi Service Facility to have the
malfunction repaired.

ing style. See owner's manual
The transmission temperature has increased sig-
nificantly due to the sporty driving manner. Drive

turns to the normal range and the indicator light
switches of.
73} 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.
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: >
115

Driving dynamic
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
116
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.
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 oF 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.
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.

Driving dynamic
— 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, which in-
creases 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 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.
I fs / I © 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
If 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.
Rear spoiler
The 3% button is located in the function bar on
the lower display. The rear spoiler increases driv-
ing stability.
The rear spoiler extends automatically at speeds
above approximately 75 mph (120 km/h). It will
retract automatically when the speed drops be-
low approximately 50 mph (80 km/h).
Applies to: RS models: The rear spoiler extends
automatically at speeds above approximately 62
mph (100 km/h). It will retract automatically
when the speed drops below approximately
37 mph (60 km/h).
You can also extend and retract the rear spoiler
manually.
> Extending: press 3% briefly.
> Retracting: press and hold 3% when driving at
speeds up to approximately 10 mph (20 km/h).
At speeds from approximately 10 mph (20
km/h) to 75 mph (120 km/h), press 3% briefly.
Z\ WARNING
— Make sure that the rear spoiler is extended
at speeds above 85 mph (140 km/h). Other-
wise, the reduced driving stability will in-
crease the risk of an accident.
—To reduce the risk of injury, make sure there
are no people or objects within range of the
rear spoiler when extending and retracting
it
@) Note
—To reduce the risk of damage, do not press
on the rear spoiler if pushing the vehicle.
—To reduce the risk of damage, never lean
against the rear spoiler or place heavy pres-
sure on it.
—To reduce the risk of damage when extend-
ing or retracting the rear spoiler, make sure
the luggage compartment lid is closed and

Trailer towing
Trailer towing
Driving with a trailer
eT e e eeu)
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.
Z\ 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 > @®.
CG) 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.
Operating instructions
Towing capacity
Your vehicle can only be operated with class 1 or
class 2 trailers.
Load distribution
Poor cargo load and distribution can negatively
impact vehicle handling. Load the trailer based
on the following criteria as much as possible:
— Store objects in the vehicle luggage compart-
ment, if possible. The vehicle should always
carry the heaviest possible load and the trailer
should have the lightest possible load.
— Distribute the load in the trailer so that the
heavy objects are as close to the axle as possi-
ble.
— Secure objects so that they do not slide.
— Utilize the maximum permitted tongue weight
if possible.
Tires
Set the tire pressure on your vehicle for a “full
load”; see the tire pressure sticker > page 284. If
necessary, also adjust the tire pressure on the
trailer according to the manufacturer's specifica-
tions.
The trailer and the vehicle should be equipped
with winter tires when driving in winter tempera-
tures.
Outside mirrors
If you cannot see the traffic behind the trailer
with the standard exterior mirrors, then you
must attach additional exterior mirrors. Adjust
them so you have a sufficient visibility behind
you.
Exterior lighting
Follow the legal regulations for lighting on your
trailer that are applicable in the country where

Trailer towing
Hill
When you start driving uphill or downhill, trailers
may tilt or sway sooner than when driving ona
level surface. If small swaying movements have
already occurred, you can stabilize the trailer by
firmly braking immediately. Never attempt to
“straighten out” the trailer by accelerating.
Conventional drive system: Downshift before
driving on hills to utilize the engine braking ef-
fect SA.
Plug-in hybrid drive system: Reduce the speed
and use the recuperation braking effect
=> page 101 to relieve the brakes > A\.
Brakes
When using a trailer with overrun brakes, first
brake gently then quickly. This reduces the risk of
jerking while braking if the trailer wheels lock up.
Engine coolant temperature
Pay attention specifically to the coolant tempera-
ture display when there are high outside temper-
atures, and when driving on long inclines
=> page 14. Shift to a higher gear in a timely man-
ner.
Z\ WARNING
Constant braking causes the brakes to over-
heat and can substantially reduce braking per-
formance, increase braking distance, or cause
complete failure of the brake system.

Driver assistance
Driver assistance
Cruise control system
Applies to: vehicles with cruise control system
The cruise control system assists the driver in
maintaining a constant speed above approxi-
mately 15 mph (20 km/h). The system maintains
the desired speed by braking and accelerating.
ZA WARNING
— Always pay attention to the traffic around
your vehicle when the cruise control system
is in operation. As the driver, you are always
responsible for controlling your vehicle
speed and the distance between your vehicle
and
other vehicles.
— For safety reasons, cruise control should not
be used in the city, in stop-and-go traffic, on
winding roads, and when road conditions are
poor (such as ice, fog, gravel, heavy rain,
and conditions that could lead to hydroplan-
ing), because this increases the risk of an ac-
cident.
— Switch the cruise control off temporarily
when driving in turning lanes, highway exits,
or in construction zones.
—To reduce the risk of an accident, you should
only resume the stored speed if it is suitable
for the current traffic conditions.
() Note
— Conventional drive system:Before driving
downhill a long distance on a steep hill, de-
crease your speed and select a lower gear.
This makes use of the engine braking effect
and reduces the load placed on the brakes.
— Plug-in hybrid drive: Before driving downhill
a long distance on a steep hill, decrease
your speed and use the recuperation braking
effect > page 101. This reduces the load on
the brakes.
@ Tips
The brake lights turn on when the brakes are
applied automatically.
