Child safety
— The child and the passenger can also injure
each other in an accident.
Never install rear-facing child safety seats or
infant carriers on the front passenger seat.
A child will be seriously injured and can be
killed when the passenger airbag inflates -
even with an Advanced Airbag System.
The inflating airbag will hit the child safety
seat or infant carrier with great force and
will smash the child safety seat and child
against the backrest, center armrest, door
or roof.
Always install rear-facing child safety seats
or infant carriers on the rear seat.
Make sure there is enough space in front of
the child in the child seat. If necessary, ad-
just the angle and position of the seat in
front of the child seat.
Forward-facing child safety seats installed
on the front passenger's seat can interfere
with the airbag when it inflates and cause
serious injury to the child. Always install for-
ward-facing child safety seats on the rear
seat.
If exceptional circumstances require the use
of a forward-facing child restraint on the
front passenger's seat, the child's safety and
well-being require that the following special
precautions be taken:
— Make sure the forward-facing seat has
been designed and certified by its manu-
facturer for use on a front seat with a pas-
senger front and side airbag.
— Always carefully follow the manufacturer's
instructions provided with the child safety
seat or carrier.
— Always move the front passenger seat to
the highest position in the up and down
adjustment range and move it back to the
rearmost position in the seat's fore and aft
adjustment range, as far away from the
airbag as possible, before installing the
forward-facing child restraint.
— Always make sure that the safety belt up-
per
anchorage is behind the child restraint
and not next to or in front of the child re-
straint so that the safety belt will be prop-
erly positioned.
— Always make sure that nothing prevents
the front passenger's seat from being
moved to the rearmost position in its fore
and aft adjustment range.
— Always make sure that the backrest is in
the upright position.
— Never place or use any electrical device
(such as a laptop, CD player, electronic
games device, power inverter or seat heat-
er for child seats) on the front passenger
seat if the device is connected to the 12-
volt socket or the cigarette lighter socket.
— If a seat heater has been retrofitted or
otherwise added to the front passenger
seat, never install any child restraint sys-
tem on this seat.
— Make sure that there are no wet objects
(such as a wet towel) and no water or oth-
er liquids on the front passenger seat
cushion.
— Never place objects on the seat (such as a
laptop, CD player, electronic games device,
power inverter or seat heater for child
seats). These may influence the electrical
capacitance measured by the capacitive
passenger detection system and can also
fly around in an accident and cause serious
personal injury.
— Always buckle the child safety seat firmly in
place even if a child is not sitting in it. A
loose child safety seat can fly around during
a sudden stop or ina collision.
— Always read and heed all WARNINGS when-
ever using a child restrained in a vehicle is
being used > page 245, Safety belts,
=> page 253, Airbag system and > page 278,
Child safety.
ZA WARNING
To reduce the risk of serious injury, make sure
that the PASSENGER AIR BAG OFF light
comes on and stays on whenever a child re-
straint is installed on the front passenger seat
and the ignition is switched on.
— Take the child restraint off the front passen-
ger seat and install it properly at one of the
rear seat positions if the PASSENGER AIR

Booster seats and safety belts
Properly used booster seats can help protect
children weighing between about 40 lbs. and 80
lbs. (18 kg and 36 kg) who are less than 4 ft. 9
in. (57 inches/1.45 meters) tall.

Fig. 230 Rear seat: child properly restrained in a booster
seat
The vehicle's safety belts alone will not fit most
children until they are at least 4 ft. 9 in. (57 in-
ches/1.45 meters) tall and weigh about 80 lbs.
(36 kg). Booster seats raise these children up so
that the safety belt will pass properly over the
stronger parts of their bodies and the safety belt
can help protect them in a crash.
> Do not use the convertible locking retractor
when using the vehicle's safety belt to restrain
a child on a booster seat.
> The shoulder belt must lie as close to the cen-
ter of the child's collar bone as possible and
must lie flat and snug on the upper body. It
must never lie across the throat or neck. The
lap belt must lie across the pelvis and never
across the stomach or abdomen. Make sure the
belt lies flat and snug. Pull on the belt to tight-
en if necessary.
> Applies to: vehicles with safety belt height ad-
justment: If you must transport an older child
in a booster seat on the front passenger seat,
you can use the safety belt height adjustment
to help adjust the shoulder portion properly.

Securing a child safety seat using a safety
ert
Safety belts for the rear seats and the front pas-
senger can be locked with the convertible locking
retractor to properly secure child safety seats.
The safety belts emergency locking retractors for
the rear seats safety belts and for the front pas-
senger’s seat safety belt have a convertible lock-
ing retractor for child restraints. The safety belt
must be locked so that belt webbing cannot un-
reel. The retractor can be activated to lock the
safety belt and prevent the safety belt webbing
from loosening up during normal driving. A child
safety seat can only be properly installed when
the safety belt is locked so that the child and
child safety seat will stay in place.
Always remember: Even though your vehicle is
equipped with an Advanced Airbag system, all
children, especially those 12 years and younger,
should always ride in the back seat properly re-
strained for their age and size.
ZA\ WARNING

Coolant loss usually indicates that there is a leak.
Immediately drive your vehicle to an authorized
Audi dealer or authorized Audi Service Facility
and have the cooling system inspected. If the
cooling system is not leaking, coolant loss can re-
sult from the coolant boiling due overheating
and then being forced out of the cooling system.
— Never open the hood if you can see or hear
steam or coolant escaping from the engine
compartment. This increases the risk of
burns. The cooling system is under pressure.
When you no longer see or hear steam or
coolant escaping, you may open the engine
compartment with caution.
—When working in the engine compartment,
