Sitting correctly and safely


that PASSENGER AIR BAG OFF #; stays
on while driving. If
PASSENGER AIR BAG OFF #¥; does not
turn on, remove the child safety seat and in-
stall it again according to the child safety
seat manufacturer instructions. If
PASSENGER AIR BAG OFF &%; still does
not turn on, the front passenger's seat must
not be used. Drive to an authorized Audi
dealer or authorized Audi Service Facility
and have the airbag system inspected.
— Fluids, electronic devices, or mechanical
damage on the front passenger's seat may
cause the front passenger seat occupant de-
tection to malfunction. The system may
then incorrectly detect if the front passeng-
er's seat is occupied. As a result, it could de-
ploy the front passenger’s airbag incorrectly
or fail to deploy it, which increases the risk
of serious or fatal injury. Make sure that no
wet objects (such as a wet hand towel) and
no fluids come into contact with the front
passenger's seat cushion. If the front pas-
senger's seat becomes wet, dry it immedi-
ately. Make sure no electronic devices (such
as a laptop or a retrofitted seat heater) are
on the front passenger's seat. Do not trans-
port any objects on or under the front pas-
senger's seat.
— Seat covers or protective covers may prevent
the advanced airbag system from correctly
detecting child safety seats or passengers in
the front passenger's seat. You must not use
seat covers or protective covers on the front
passenger's seat that are not specifically ap-
proved for use on Audi seats with an ad-

vanced airbag system.

the event of an accident. Always secure the
child safety seat according to the manufac-
turer instructions.
— Children or babies must not under any cir-
cumstances be held on the lap of the driver
or other passengers while driving.
— Do not secure more than one child in a child
safety seat.
— Never allow a child to sit in a child safety
seat unsupervised.

Driving


do not inadvertently press the accelerator
pedal and always shift into “P” when the ve-
hicle is stopped.
— If you leave the vehicle, switch the ignition
off and take the key with you. This is espe-
cially important when leaving persons or an-
imals in the vehicle. Otherwise, the vehicle
could start unintentionally, the parking
brake could release, or electronic equipment
could activate, which increases the risk of an
accident.
— No persons or animals should be left in a
locked vehicle. Locked doors make it more
difficult for emergency workers to enter the
vehicle, which puts lives at risk.
— If you do not begin driving immediately af-
ter releasing the brake pedal, your vehicle
may begin to roll backward. Press the brake
pedal
or set the parking brake immediately.
@) Note
If you have to stop on an incline, always press
the brake pedal to hold the vehicle in place to
reduce the risk of the vehicle rolling back-
ward. Do not try to hold the vehicle in place
by pressing and holding the accelerator pedal.
The transmission can overheat, which increas-
es the risk of damage.
Hill hold assist
If you take your foot off of the brake pedal when
driving on hills, the braking force will be held for
several seconds. At that time, you can start driv-
ing without the vehicle rolling backward.

Requirement: the driver's door must be closed,
the engine must be on, and the vehicle must be
traveling uphill.
> To activate hill hold assist, press and hold the
brake pedal for several seconds while the vehi-
cle is stationary.

ZA WARNING
— If you do not begin driving immediately af-
ter releasing the brake pedal, your vehicle
may begin to roll backward. Press the brake

pedal or set the parking brake immediately.

— The hill hold assist cannot hold the vehicle
on inclines in every scenario (for example,
on slippery or icy ground).

The automatic transmission shifts automatically
depending on the selected gear and the current
driving style. When driving with a moderate driv-
ing style, upshifting early and downshifting late
will help to improve fuel economy. When driving
with a sporty driving style, the transmission per-
mits higher RPMs.

Driving

“N” (Neutral) gear
In the “N” gear, power is not transmitted to the
driving wheels. Use the “N” gear in a car wash
(with conveyor belts), for example.
If you unintentionally select “N” while driving
(faster than 1 mph (2 km/h)), you can also shift
back to “D” without pressing the brake pedal.
For safety reasons, the vehicle cannot be locked
when the transmission is in the "N” gear.
“Pp” (Park) gear
Requirement: the ignition must be switched on.
The vehicle is secured from rolling away by the
parking lock when in the “P” gear.
— Bring the vehicle to a full stop and press the
brake pedal.
— Press the “P” button @) on the selector lever.
— The “P” next to the selector lever will light up.
“P” engages automatically if you switch the en-
gine off while the “D” or “R” gear is selected. If
you switch the engine off in “N”, “P” will engage
automatically after approximately 30 minutes.
If you want to switch from “P” to “D” or “R”, the
engine must be running.
If you cannot shift out of “P”, for example be-
cause the vehicle has no power, you may need to
use the emergency release for the parking lock
=> page 100.
Selecting a driving program
Various driving programs can be selected when in
the “D” gear. The programs influence when the
transmission shifts and how the accelerator ped-
al responds.
The selected driving program is displayed in the
instrument cluster.
—D (Drive): normal driving mode
— S (Sport): sporty driving mode
If you select the Dynamic mode in Audi drive se-
lect*, the “S” driving program will be activated.
When the ignition is switched off, the driving pro-
gram may be reset to “D”.
98
To switch between the current driving program
and “S”, push the selector lever toward the rear.

ZA WARNING
— Before you start driving, check if the label
for the desired selector lever position next
to the selector lever is lit up.
— Secure the vehicle against rolling before ex-
iting the vehicle > page 96.
— Power is still transmitted to the wheels
when the engine is running at idle. To pre-
vent the vehicle from “creeping”, you must
keep your foot on the brake in all selector
lever positions (except "P" and "N") when
the engine is running.
— To reduce the risk of an accident, do not
press the accelerator pedal when changing
gears if the vehicle is stationary and the en-
gine is running.
— Never select the “R" or "P” gears while driv-
ing. Doing so could cause an accident.
— The vehicle can roll even if the ignition is
switched off.

@) Tips
If you shift between “D” and “R” within one
second, you do not need to press the brake
pedal. This makes it possible to “rock” if it is
stuck, for example.
