Special driving situations
Driving uphill and downhill
When driving uphill, downhill, or at high alti-
tudes, note the following information:
— 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 92. This reduces the load
on the brakes.
— Use the hold assist if necessary > page 97
— Use the hill descent assist if necessary
=> page 99

Z\ 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.

Driving dynamic

The vehicle ground clearance is adjusted by the
air suspension* based on the setting.
Suspension
PNET La mela) le)
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-
102
tion may only be used temporarily when in-
creased ground clearance is necessary. It is not
intended for long drives.
C) Note
— Also refer to the information about ground
clearance > page 102.
— 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 permit-
ted because the pressure in the air suspen-
sion struts can change during transport. The
vehicle 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.
BB Air suspension: malfunction! You may con-
tinue driving slowly at max. XX mph (km/h)
