Special driving situations
Driving uphill and downhill
Please note the following when driving on in-
clines and hills:
— Drive slowly and carefully.
— Do not try to turn around if you cannot safely
drive on an incline or hill. Instead, drive in re-
verse.
— When driving down hills, use the recuperation
braking effect > page 90. This reduces the load
on the brakes.
— Use the hold assist if necessary > page 94
— Use the hill descent assist if necessary
=> page 97

ZA WARNING
— Only drive on inclines that your vehicle is de-
signed to handle. Do not exceed the hill
climbing ability of your vehicle. Your vehicle
could tip or slide.
— Do not drive at an angle on steep inclines
and hills. If your vehicle is about to tip, you
must immediately start steering in the di-
rection of the downward slope to reduce the
risk of an accident.
— Always be ready to brake when using the hill
descent control function.

96
Offroad driving
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
= page 99 and drive across raised areas of the
ground with the wheels on one side of the vehi-
cle, instead of allowing the center of the vehi-
cle 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 98
— Hill descent assist* > page 97
— Raising the vehicle > page 99
— Limit ESC > page 102

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.
(Gi) Tips
Clean your vehicle after driving offroad. Dirt
and stones falling off your vehicle can affect
other road users.
PUN Mele mules
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.
— Drive carefully and no faster than at walking
speeds to prevent the front of the vehicle from
creating waves, because they could splash >

Suspension*
The suspension > page 99 adjusts to be tighter
or more comfort-oriented when it comes to
damping of uneven spots on the road.
The vehicle ground clearance is adjusted by the
air suspension* based on the setting.
Suspension
Adaptive dampers
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.
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:
VEHICLE > 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 indicated by a red outline.
Raising the vehicle
> Applies to: MMI: Select on the home screen:
VEHICLE > 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 when at speeds of approxi-
mately 22 mph (35 km/h) and lower. This func-
tion may only be used temporarily when in-
creased ground clearance is necessary. It is not
intended for long drives.
C) Note
When transporting the vehicle on a road carri-
er, rail carrier, ship carrier, or other carrier, it
may only be secured at the running surfaces
of the tires (circumference). Securing the ve-
hicle at the axle components, suspension
struts, or towing eyes is not permitted be-
cause the pressure in the air suspension
struts can change during transport. The vehi-
cle might not be secured sufficiently if this
happens.
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*

Z\ 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.
