Offroad driving
Applies to: allroad
Your vehicle is not an offroad vehicle. Note the
following points when driving offroad:
— Drive slowly and carefully.
—To reduce the risk of underbody damage, pay
attention to the vehicle's ground clearance and
drive across raised areas of the ground with the
wheels on one side of the vehicle, instead of al-
lowing the center of the vehicle to pass over the
raised areas.
— To reduce the risk of becoming stuck, drive
through sandy or swampy areas at a steady
speed and without stopping, if possible.
If necessary, use the following functions:
— Audi drive select* Offroad mode > page 110
— Hill hold assist* > page 108
— Limit ESC > page 114

ZA WARNING
Only drive in terrain that is suitable for the ve-
hicle and your driving ability.

@ For the sake of the environment
Avoid actions that are damaging to the envi-
ronment. Show respect for the natural envi-
ronment and remain on marked routes.
G) Tips
Clean your vehicle after driving offroad. Dirt
and stones falling off your vehicle can affect
other road users.
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
108
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.

ZA WARNING
After driving through water, press the brake
pedal carefully to dry the brakes so that the
full braking effect will be restored.
@) Note
Vehicle components such as the engine, drive
system, suspension, or electrical system can
be severely damaged by driving through wa-
ter
Gi) Tips
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.
Hill descent assist
Applies to: vehicles with hill hold assist


The “2 button is located above the selector lever
in the center console. It lights up when the sys-
tem is turned on.
Hill descent assist can assist you when driving
down hills by maintaining a constant vehicle
speed by automatically braking all four wheels.
You can adjust the speed using the accelerator
and brake pedals. The regulation depends on the
hill and the vehicle speed.
> Switching on: press “2.
> Switching off: press “2 again.
Active regulation
Regulation begins shortly after you start driving
and is possible at speeds up to approximately 19
mph (30 km/h) and on hills that have an approxi-
mately 6-60% grade. If these conditions are met,
regulation will be activated and the indicator
light will turn on.

Driving dynamic

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.
Dynamic steering: correcting steering wheel
position
The steering is reinitializing. The steering wheel
will move easily after starting the vehicle. Reiniti-
alization might be necessary if the steering wheel
was moved while the engine was switched off.
The display turns off if the initialization was suc-
cessful.

ZA\ 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 Ba or fal 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 113.
Applies to: vehicles with quattro ultra: If the driv-
ing situation does not require all wheel drive,
then the rear section of the drivetrain will decou-
ple to save fuel. The system constantly deter-
mines and anticipates if all wheel drive is needed.
This allows the rear drivetrain to recouple shortly
before it is needed.
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
112
snow and ice. Always read and follow safety pre-
cautions > A\.

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.
Sy amet
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.

Driving dynamic


these control systems are installed and this
can affect driving stability and increase the
risk of a collision.

Gi) 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.
The So button (or 2, 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.
When ESC is limited, allroad models switch to
Offroad mode. All other model versions switch to
Sport mode. Sport mode is particularly suited for
driving on an even road surface. Offroad mode is
designed for uneven terrain or loose ground.
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.
114
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.
(i) 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.
BB /ABS} / 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.

Driver assistance

Messages
If and a message with Predictive control is
displayed when there is a malfunction, the effi-
ciency assist functions are unavailable or limited.
A message that indicates the cause and possible
solution may appear with some displays. The
weather conditions may be too poor or a sensor
may be covered. Clean the area in front of the
sensors > page 119 and try to turn on the sys-
tems again later.
If the malfunction remains, drive to an author-
ized Audi dealer or authorized Audi Service Facili-
ty immediately to have the malfunction correct-
ed.

ZA WARNING
— Observe the safety precautions and note the
limits of the assist systems, sensors, and
cameras > page 117.
— Pay attention to traffic and the area around
your vehicle when predictive control is
switched on. The driver is always responsible
for assessing the traffic situation.
— The system does not consider “right of way”
rules and does not respond to traffic lights,
so lack of driver attention in these situations
can increase the risk of an accident.
— The speed when driving through curves may
be different from what you as a driver would
do or may not be suitable for the weather
and road conditions. If necessary, apply the
brakes and reduce the selected speed to be
maintained in the Adjustment to curves
along route setting to reduce the risk of an
accident.

@ Tips
— Predictive control can exceed or drop below
the maximum permitted speed. The driver
is responsible for adhering to the permitted
speed limit.
— The traffic signs on the road always take pri-
ority over the display. The driver is always
responsible for adhering to the regulations

D_ In certain countries
134
applicable in the country where the vehicle
is being operated.
— Ifa speed limit is detected, the marking @
= page 131 of the set speed limit will be ad-
justed even if Audi adaptive cruise control is
not actively regulating.
— Control by the system depends on which
adaptive cruise control driving program is
set or on the selected Audi drive select*
mode.
— After switching on the ignition and first
driving onto a freeway or similar road with-
out a speed limit, the system will regulate
the speed to 80 mph (130 km/h). Then
the system adjusts to the last speed set by
the driver.
— There is no adaptation to speed limits when
driving through highway interchanges and
when driving on or off the expressway.
— The system can fail to provide control or the
control may be faulty if the values from the
camera-based traffic sign recognition* are
incorrect or the navigation system map data
is outdated.
— When route guidance is switched on, the
system adapts to the route provided by the
navigation system. Driving without route
guidance or leaving a route can result in
faulty control.

The newly-set distance will be shown briefly, for
example with the [eg indicator light. In the Driv-
er assistance display, a graphic display is shown
instead of the indicator lights > page 131,
fig. 108. The display matches the functions of
the indicator lights.
When approaching a vehicle driving ahead, the
adaptive cruise control system brakes to match
that vehicle's speed and then adjusts to the set
distance. If the vehicle driving ahead accelerates,
then the adaptive cruise control will accelerate
up to the speed that you have set.
The following distances can be set:
