than one person, including children, with a
single safety belt.
— Never allow children or infants to ride on an-
other person's lap and be belted into the
safety belt with them.
— Insert the belt buckle only in the belt latch
belonging to the corresponding seat, so that
the protective function is not impaired.
— To ensure the maximum protective function
of the safety belts, all vehicle passengers
must sit in the correct seating position
=> page 72.
— Check the condition of your vehicle’s safety
belts regularly. If you find damage to the
belt webbing, the belt connections, the re-
tractor, or the buckle, have the damaged
safety belt replaced by an authorized Audi
dealer or authorized Audi Service Facility.
— The safety belts must not be removed or
modified in any way. Do not attempt to re-
pair the safety belts yourself.
— Safety belts that are strained during an acci-
dent, and thus stretched, must be replaced
by an authorized Audi dealer or authorized
Audi Service Facility.

Fig. 74 Safety belt positioning for pregnant women
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. 73.
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. 74.

Z\ 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,

Fig. 78 Airbag overview image (enlarged section: deployed airbags)
The locations of the airbags are labeled with
“AIRBAG”. The following airbags are installed in
your vehicle:
Driver's airbag
Front passenger's airbag
Front and rear side airbags
Side curtain airbags
Equipped on some models: front and rear
central airbags
®@

Knee airbags
Airbags offer the best possible protection in your
vehicle during an accident when they are used to-
gether with safety belts that are fastened cor-
rectly, and when passengers are sitting in the cor-
rect seating position. Airbags are a supplementa-
ry restraint system and do not replace safety
belts.
Airbags may deploy during front-impact, side-im-
pact, or rollover accidents.
The deployment area for the airbag system can-
not be defined for every situation, since the cir-
838
cumstances surrounding accidents can vary wide-
ly. Factors that play an important role include the
condition of the object that the vehicle hits (hard
or soft), the angle of impact, vehicle speed, etc.
The deciding factor for the deployment of the air-
bag system is the deceleration that occurs during
an accident. Sensors in the vehicle are designed
to detect the severity of an accident in conjunc-
tion with the control module, and to provide a
targeted and timely deployment of the restraint
system. If the vehicle deceleration that is meas-
ured during an accident is below the specified
reference values in the control module, then the
airbags will not deploy, even though the vehicle
may be severely damaged from the accident. In
these cases, the vehicle occupants will be pro-
tected by the safety belts if they are fastened and
worn correctly.
The deployment of the front passenger's airbag
will depend on the occupancy of the seat
=> page 89.

Stowing and using

— Holders for a notepad and a pen in the glove
compartment
— Storage compartments in the door trim panel
— Net in the front passenger's footwell
— Storage compartments under the center arm-
rest
— Compartments on the backrests of the front
seats
— Garment hooks in the rear
— Cell phone holder in the right rear door
— Bag hooks in the luggage compartment
— Net in luggage compartment
— Umbrella holder
> Stow heavy luggage as far forward in the lug-
gage compartment as possible.
> Use non-elastic cords attached to the tie-downs
to secure objects.


ZA WARNING
— To reduce the risk of injury, make sure all
storage compartments are always closed
while driving.
— Loose objects can be thrown around the ve-
hicle interior during sudden driving or brak-
ing maneuvers, which increases the risk of
an accident. Store objects securely while
driving.
— Only use the storage compartments in the
door trim panels to store small objects that
will not stick out of the compartment and
impair the function of the side airbags.
— Only lightweight clothing should be hung
from the garment hooks in the vehicle. Do
not use clothes hangers to hang clothing.
The pockets of the clothing must not con-
tain any heavy, breakable, or sharp-edged
objects. This could impair the effectiveness
of the side curtain airbags.
— Make sure your view toward the rear is not
blocked, for example by hanging clothing or

objects in the vehicle.

Luggage compartment
General information
All pieces of luggage or objects must be securely
fastened in the luggage compartment. Note the
following to maintain good vehicle handling:
> Distribute the load evenly in the luggage com-
partment.
100

ZX WARNING
— 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 342.
— 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 82.

Brakes
General information
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.
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
be delayed. Other factors that could temporarily
increase the response time of the brakes include:
— Wet conditions
— Low temperatures, ice, and snow
— Roads covered in salt
— Dirty brake pads
Corrosion
Corrosion may form on the brake rotors if there is
no heavy braking, if the vehicle is not driven for
long periods of time, or if the vehicle is not driv-
en
frequently or for long distances. In this case,
braking heavily several times while driving at
high speeds can clean the brake rotors > A\.
Brake pads
New brake pads do not achieve their full braking
effect during the first 250 miles (400 km). They
must be “broken in” first. However, you can com-
pensate for the slightly reduced braking force by
pressing firmly on the brake pedal. Avoid heavy
braking during the break-in period.
Brake pad wear depends largely on the way the
vehicle is driven and on operating conditions.
Brake pad wear increases when driving frequently
in the city or short distances or when using a very
sporty driving style.
Ceramic brakes
Applies to: vehicles with ceramic brakes
Ceramic brakes provide excellent deceleration
rates.
The break-in period for new ceramic brakes may
be significantly longer than for standard brake
rotors. Due to the properties of the material,
they may cause noises at lower speeds. Ceramic
brakes also absorb more moisture in wet condi-
tions. Therefore, there will temporarily be less
braking force than when the brakes are dry. You
can compensate for this by pressing the brake
pedal harder.

ZA\ WARNING
— Only apply the brakes for the purpose of
cleaning the brake system when road and
traffic conditions permit. You must not en-
danger other road users and increase the
risk of an accident.
— Due to the risk of injury, only have an au-
thorized Audi dealer or authorized Audi
Service Facility work on the brake system.
Incorrect repairs could impair the function.
— Never let the vehicle roll while the engine is
stopped because this increases the risk of an
accident.
— During automatic braking maneuvers, the
brake pedal may move downward automati-
cally. To reduce the risk of injury, do not
place your foot under the brake pedal.
