Sitting correctly and safely

Correct safety belt positioning

B4H-0751


RAZ-0696


Fastened safety belts only offer optimal protec-
tion during an accident and reduce the risk of se-
rious injury or death when they are positioned
correctly. Furthermore, the correct safety belt
position holds the vehicle occupant in place so
that a deployed airbag can provide maximum
protection. Therefore, always fasten the safety
belt and make sure it is positioned correctly
> fig. 54.
To ensure the safety belt is positioned correctly,
make sure of the following points:
— The lap portion of the safety belt must be locat-
ed across the lap.
—The shoulder portion of the safety belt must
rest over the center of the shoulder.
— The safety belt must always rest flat and se-
curely on the body.
For pregnant women, the safety belt must rest
evenly across the chest and as low and flat as
possible on the lap, so that no pressure is applied
to the lower abdomen. This should be done
throughout the entire pregnancy > fig. 55.


ZA\ WARNING
Incorrect safety belt positioning can cause se-
rious injury in the event of an accident or dur-
ing sudden braking or driving maneuvers.
— Never drive with the backrest reclined ex-
tremely far. The more the backrest is tilted
back, the greater the risk of injury due to the
safety belt being routed incorrectly.
— The safety belt itself or a loose safety belt
can cause serious injuries if it shifts onto
soft areas of the body, such as the stomach.
— The shoulder portion of the safety belt must
lie over the center of the shoulder and
chest, and never under the arm, behind the
back, or across the neck or face.
— The lap portion of the safety belt must lie
across the lap and never over the stomach.
—The safety belt must lie flat and securely on
the upper part of the body and the lap.
— The belt webbing must not be pinched or
twisted, or rub against sharp edges.
— If the safety belt height is set incorrectly
and/or the safety belt is routed incorrectly,
then the safety belt's protective function
will be impaired in the event of an accident.
Make sure the safety belt is at the right
height and is routed correctly for the pas-
senger using it.
— A safety belt that is too loose may lead to in-
juries during an accident, because your body
will move farther forward due to kinetic en-
ergy and will be stopped abruptly by the
belt.
— Heavily bulky, loose clothing (for example, a
coat over a sports jacket) may prevent the
seat and safety belts from functioning cor-
rectly.
— Do not position the safety belt over hard or
breakable objects (such as glasses, pens,
etc.).
—The lap belt portion of the safety belt must
sit as low as possible on the lap of pregnant

women and lie flat under the belly.

@) Note
Make sure that there are no hook-and-loop
fasteners or sharp objects such as zippers or

Storage and convenience


cover is not a surface for storing objects. Ob-
jects placed on the cover increase the risk of
injury to all vehicle occupants during sudden
driving or braking maneuvers or in the event
of an accident.
— Applies to: vehicles with luggage compart-
ment cover: The luggage compartment cov-
er must always be securely fastened when in
use to reduce the risk of an accident.
— Loose objects can be thrown around the ve-
hicle interior during sudden driving or brak-
ing maneuvers, which increases the risk of
an accident. Always stow objects securely in
the luggage compartment and secure them
at the tie-downs. Use straps suitable for
heavy objects.
— If pieces of luggage or objects are secured
to the tie-downs with unsuitable or dam-
aged straps, this can increase the risk of in-
jury during braking maneuvers or accidents.
— When transporting heavy objects, the vehi-
cle characteristics will change due to the
shift in the center of gravity, which increases
the risk of an accident. You may need to
adapt your driving style and speed to the
current conditions.
— The cargo net* is only strong enough to se-
cure light objects. Heavy objects are not ade-
quately secured. Attempting to secure heavy
objects increases the risk of injury.
— Never exceed the permitted axle and load
and vehicle weight > page 291.
— Never secure a child safety seat to the tie-
downs.
— Never leave your vehicle unattended, espe-
cially if the luggage compartment lid is
open. Children could enter the luggage com-
partment and close the luggage compart-
ment lid from the inside. This creates the
risk of fatal injury, since the children would
be locked in and may not be able to escape
by themselves.
— Do not allow children to play in or on the ve-
hicle. Close and lock the luggage compart-
ment lid as well as all other doors when you
leave
the vehicle.
— Never transport passengers in the luggage
compartment. Every passenger must be cor-


rectly secured with the safety belts in the
vehicle > page 64.
— Be careful when releasing the backrest and
folding
it forward. To reduce the risk of be-
ing pinched, pay attention and check when
folding backrests forward.
— The backrest must be securely latched so
objects cannot slide forward out of the lug-
gage compartment during sudden braking.
— The backrest must be latched securely to en-
sure that the safety belt is protecting the
center seating position.
— Always pull forward on the backrest to make
sure it is check if it is correctly locked in
place.

@) Note
—To reduce the risk of damage, move the rear
head restraints down > page 63 before fold-
ing the rear backrests forward.
— When folding the backrest forward, make
sure the outer safety belts are in the belt
guide recess so that they do not get pinched
in the backrest lock and damaged. Other ob-
jects should be removed from the rear
bench seat to protect the backrest from
damage.
— If you move the front seat back when the
rear seat backrest is folded forward, you
could damage the head restraints on the
rear seat.
— Make sure that the heating grid strips for
the rear window defogger are not damaged
by abrasive objects.
— Applies to: vehicles with manual luggage
compartment cover: Let the luggage com-
partment cover roll up slowly to reduce the
risk of damage.
@ Tips
— The tire pressure must be adapted to the
load > page 251.
— You can purchase straps at specialty stores.

Driving


ZA\ WARNING
Other road users may not be able to defini-
tively hear electric vehicles when they are
driving. This increases the risk of an accident
particularly when driving in areas with little
traffic, when maneuvering, or when driving in
reverse.

ient and environmentally-friendly

i}
Your driving style greatly influences the amount
of fuel and energy consumed, the environmental
impact, and the wear on the motor, brakes, and
tires. Note the following information for efficient
and environmentally-conscious driving:
— Select the Audi drive select* efficiency mode.
— Turn off electrical equipment that is not need-
ed, for example seat heating*.
— Anticipate upcoming traffic situations while
driving to avoid unnecessary acceleration and
braking.
— Avoid driving at high speeds.
— Avoid adding extra weight to the vehicle if pos-
sible, for example by not leaving roof racks or
bike racks installed when they are not needed.
— Make sure the tire pressure is correct.
— Have maintenance performed regularly on the
vehicle.
— Do not drive with winter tires during the summ-
er.
— Brake early and evenly to use recuperation.

Audi Service Facility to have the malfunction cor-
rected.
oO Drive system: warning! Limited performance
The driving power is limited. The high-voltage
battery may not be sufficiently charged or is at
the operating temperature threshold, for exam-
ple, when the outside temperatures are extreme-
ly cold.
BS Vehicle sound: malfunction! Pedestrians

Brakes
ere el eiy
You can apply the vehicle's brakes using the brake
pedal.
Operating noise
Noises may occur when braking depending on the
speed, braking force, and outside conditions such
as temperature and humidity.
When the vehicle is stationary, the brake system
performs system tests at regular intervals. This
can cause brief noise and haptic feedback effects
on the brake pedal.
Braking effect
The response time from the brakes depends on
the weather and environmental conditions. To
ensure the optimal braking effect, the brake sys-
tem is cleaned at regular intervals. This is done
by applying the brake pads to the brake rotors for
a short period of time when driving at high
speeds when the windshield wipers are switched
on.
If the brake system becomes damp, for example
after driving in heavy rain, the braking effect may >

Suspension
CET tes un) Led
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: VE-
HICLE > 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 highlighted in color.
Raising the vehicle
> Applies to MMI: Select on the home screen: VE-
HICLE > 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 at speeds of approximately
22 mph (35 km/h) and below. This function may
only be used temporarily when increased ground
clearance is necessary. It is not intended for long
drives.
CG) Note
—Also refer to the information about ground
clearance > page 103.
— 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*

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.
CG) 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.
B Air suspension: malfunction! You may con-
tinue driving slowly at max. XX mph (km/h)

if possible.
Tires
Set the tire pressure on your vehicle for a “full
load”; see the tire pressure sticker > page 251. If
necessary, also adjust the tire pressure on the
trailer according to the manufacturer's specifica-
tions.
The trailer and the vehicle should be equipped
with winter tires when driving in winter tempera-
tures.
Outside mirrors
Make sure that you can also observe the traffic
area behind the vehicle using the exterior mir-
rors, and use additional exterior mirrors if neces-
sary. Adjust the additional exterior mirrors so
that you have a sufficient visibility behind the ve-
hicle. Follow the local legal regulations for instal-
ling additional exterior mirrors.
Exterior lighting
Follow the legal regulations for lighting on your
trailer that are applicable in the country where
you are operating the vehicle. Contact an author-
ized Audi dealer or authorized Audi Service Facili-
ty for more information.
Before you start driving, check all lighting equip-
ment on the trailer while it is hitched to the vehi-
cle.
The headlight range control automatically ad-
justs the light range of the headlights.
Safety chains
Make sure the safety chains are correctly applied
when pulling a trailer. The chains should hang
enough so that the trailer can drive around
curves. However, they must not touch the
ground.
Air suspension
Applies to: vehicles with air suspension
The Audi drive select* comfort mode > page 102
must be selected before you adjust the tongue
weight on the trailer and hitch the trailer >@,

level will no longer be available, even if you are
lowering the vehicle manually.

ZA WARNING
Applies to: vehicles with air suspension
— Never turn off trailer mode while driving
when a trailer is hitched, because then the
restrictions for controlling the vehicle level
will be turned off.
— Driving with a trailer on unpaved roads when
the vehicle is raised may change the vehicle
handling. Adapt your speed.
— Note that the vehicle will lower automatical-
ly at certain speeds if you have lifted the ve-
hicle manually.
