Sitting correctly and safely

— The distance between your upper body and the
steering wheel or instrument panel is at least
10 inches (25 cm)
— The distance between your knees and the in-
strument panel is at least 4 inches (10 cm)
— Your thighs are lightly supported by the front
surface of the seat
— The backrest is in an upright position and your
back
is resting against it
— You have a sufficient view of the area around
the vehicle
— You have a clear view of the instrument cluster,
indicator lights, and the head-up display*
Seat settings menu: quick access
If you press on the image of the driver's or front
passenger's seat in the climate control system
menu & page 100, fig. 89 @, you will go directly
to the seat settings for that seat.

ZA WARNING
— If you are too close to the steering wheel or
instrument panel, the airbag system cannot
provide the optimal protection, which in-
creases the risk of injury and death.
—To reduce the risk of injury in the event of
sudden braking maneuvers or accidents,
never drive with the backrest reclined very
far. The airbag system and seat belts can on-
ly provide optimal protection when the back-
rest is in an upright position and the driver
is wearing the seat belt correctly. If the
backrest is angled back too far, the safety
belt can shift to soft areas of the body, such
as the stomach, which increases the risk of
injury.
—To reduce the risk of an accident, only adjust
the seats when the vehicle is stationary.
— Be careful when adjusting the seat. Lack of
control or attention when adjusting can re-
sult in injuries due to pinching to vehicle oc-
cupants both in the front seats and rear
seats.
— Never place objects in the driver's footwell.
Objects could shift and enter the area
around the pedals, which could prevent you
from using them. You would then be unable
to use the pedals if sudden driving or brak-

ing maneuvers were needed, which increas-
es the risk of an accident.
— Make sure that the floor mats are always se-
curely attached.
—To reduce the risk of an accident, never place
additional floor mats or other floor covers
over the installed floor mats, because this
reduces the pedal's range of motion and can
impair pedal operation.
—To reduce the risk of injury, never place your
feet on the instrument panel, out of the
window, or on the seat surfaces. This also
applies to passengers in the rear seats.
G) Tips
At the same time, only move the respective
seat using the controls.

Belt retractor lock
The safety belts on the rear seats and on the
front passenger seat are equipped with a belt re-
tractor lock.
> If you secure a child safety seat with a safety
belt, the belt retractor lock on the safety belt >

Sitting correctly and safely

may need to be activated. Follow the instruc-
tions from the child safety seat manufacturer.
>» When a vehicle passenger has fastened a safety
belt, the belt retractor lock should not be acti-
vated. If the belt retractor lock has been acti-
vated unexpectedly, deactivate it.
Deactivating or activating the belt retractor lock
=> page 91.
Safety belt retractor
The safety belts are equipped with an automatic
belt retractor. This automatic retractor allows the
safety belt to be pulled all the way out when the
belt is pulled slowly. However, the automatic re-
tractor locks during sudden braking maneuvers.
It also locks the belts when accelerating, driving
uphill, and driving around curves.
Belt force limiter
Safety belts with belt force limiters reduce the
force placed on the body by the safety belts dur-
ing a collision.
Safety belt pretensioners
Safety belts may be tightened with reversible
belt tensioners when you start driving and in cer-
tain driving situations. If the safety belt is too
loose, it will be tightened so that the belt will
rest closer to the body.
In some collisions, pyrotechnic belt tensioners
may secure the safety belts so that they cannot
loosen. This reduces forward movement by the
vehicle passengers.

Z\ WARNING
The pyrotechnic system can only provide pro-
tection during one collision. If the pyrotechnic
belt tensioners deploy, the pretensioning sys-
tem must be replaced by an authorized Audi
dealer or authorized Audi Service Facility.

@) Tips
Smoke may be released when pyrotechnic belt
tensioners deploy. This is not a sign of a vehi-
cle fire.

engine, basic power supply) > page 285, 12
Volt vehicle battery or > page 286, Other bat-
tery types
— Auxiliary battery (for example, for recuperation
or optional equipment) > page 286, Other bat-

troduction.
Not running the vehicle for long periods of
time
The battery will gradually drain if the vehicle
does not run for long periods of time. To ensure
that the vehicle can still be started, the electrical
equipment will be limited or switched off. Some
convenience functions, such as interior lighting
or power seat adjustment, may not be available
under certain circumstances. The convenience
functions will be available again when you start
the
engine.
Even when electrical equipment is switched off,
the equipment can still drain the battery if the
vehicle is not driven for long periods of time.
Deep draining results in a chemical reaction that
destroys the inside of the battery. The battery
must be charged every month to prevent this
= page 286. Contact an authorized Audi dealer or
authorized Audi Service Facility for more infor-
mation.

sories contain lead and lead compounds,
chemicals known to the State of California
to cause cancer and reproductive harms.
Wash hands after handling.
@) Note
— If the vehicle will be parked for long periods
of time, protect the battery against the cold
so that it will not be destroyed by “freezing”
=> page 286, Charging the 12 Volt vehicle
battery.
— There are electrical components under the
cargo floor behind a trim panel that warm
up during operation. To reduce the risk of
the components overheating, do not store
objects such as blankets under the cargo
floor. If the components overheat, they will
switch off temporarily. This will be indicated
by a message that will be displayed in the
instrument cluster until the temperature re-
turns to normal.
