Driving

@ 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.
@ 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
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.
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 a
> 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.
Ready mode
If one of the requirements for active regulation is
not met, the system will be in ready mode. The
a indicator light will turn on. Once the require-
ments are met again, the system will be able to
provide active regulation again.

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.
@ 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.

ZA WARNING
— Be ready to apply the brakes at all times
when using the hill hold assist.
— Always adjust the speed to the visibility,
weather, road, and traffic conditions. The
system cannot replace the driver's atten-
tion.
— The system cannot maintain a constant vehi-
cle speed in all situations, for example when
on smooth or slippery ground. This can in-
crease the risk of an accident.
G) Tips
If you select the Audi drive select* Offroad
mode, hill descent assist will switch on.

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 sie 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:
VEHICLE > 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 ESC will be restricted and the hill de-
scent assist* will be activated. The vehicle will ex-
it this mode after the ignition is switched off.
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.
106
Individual - Provides the option for personalized
vehicle settings. Press [7 to configure the mode
= page 106, Individual settings.
G) Tips
When the ignition is being switched on, indi-
vidual systems, such as the drive system, will
be reset to a balanced setting. Select the cur-
rent mode again to attain its full configura-
tion.
Individual settings
Applies to: vehicles with Audi drive select
The equipment in your vehicle will determine
which settings you can adjust.
Drive
The drive system will react to accelerator pedal
moves more quickly or in a more balanced man-
ner. The shift points are located in higher or low-
er engine speed ranges on vehicles with automat-
ic transmissions.
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 108.
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.
Engine sound
The engine sound adapts and can be subtle to
sporty.
Suspension
Adaptive dampers
Applies to: vehicles with suspension control
The adaptive dampers are an electronically-con-
trolled damping system. The firmness of the >

suspension will adapt to the driving conditions
and the driving situation. 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

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.
Hi Suspension: malfunction! You can continue
driving


There is a malfunction. See an authorized Audi
dealer or authorized Audi Service Facility for as-
sistance.
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.
Dynamic steering
Applies
to: vehicles with dynamic steering
The driving dynamic and driving stability are in-
creased by the steering ratio based on the speed.
At reduced speeds, steering is direct in order to
provide agile steering behavior and keep the
steering effort as minimal as possible when the
driver is maneuvering the vehicle. This sets the
steering to be less sensitive at higher speeds in
order to provide improved vehicle control.
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! You can continue
driving
There is a malfunction in the steering system.
Steering may be more difficult or more sensitive.
Adapt your driving style. Have the steering sys-
tem checked immediately by an authorized Audi
dealer or authorized Audi Service Facility. Please
note that the red indicator light may turn on af-
ter restarting the engine. Do not continue driving
if it does.
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.
@) Tips
—If there is a malfunction, the steering wheel
may be crooked when driving straight.
—Ifthe a or Ee indicator light only stays on
for a short time, you may continue driving.
