Driving sa fe ty
Loose items in the luggage compartment can
shift s udden ly, changing vehicle handling charac­
ter istics. Loose items can also increase the risk of
serious personal in jury in a sudden vehicle
ma­
neuver or in a coll is ion.
.,. Distribute the load evenly in the luggage com­
partment .
.,. Always place and properly secure heavy items in
the luggage compartment as low and as far for­
ward as possible
c> fig . 226 .
.,. Secure luggage us ing the tie-downs provided
¢ page 73 .
.,. Make su re that the rea r seatbac k is securely
latched in place.
A WARNING
Improperly stored luggage or othe r items can
fly through the vehicle causing serious per­
sonal injury in the event of hard braking or an
accident. To help reduce the risk of serious
personal injury:
- Always put objects, for example, luggage or
other heavy items in the luggage compart­
ment.
- Always sec ure objects in the luggage com­
partment using the tie-down eyelets and
s u itable straps.
A WARNING
Heavy loads will influence the way your vehi­
cle handles. To he lp reduce the r isk of a loss
of contro l leading to serious pe rsonal i njury:
- Always keep in mind when transporting heavy objects, that a change i n the center of
grav ity can also cause changes in vehicle
hand ling:
- Always distr ibute the load as even ly as
possible.
- Place heavy objects as far forward in the
luggage compartment as poss ible.
- Never exceed the Gross Axle Weight Rating
o r the Gross Vehicle Weight Rating specified
on the safety compliance sticker on the driv­
er's side B-pillar respective ly on the front
end of the driver's door. Exceeding permissi­
ble weight standards can cause the veh icle
to slide and handle differently .

-Please observe info rmation on safe driving
¢page 254.
A WARNING
To he lp prevent po isonous exhaust gas from
being drawn into the vehicle, always keep the
rear lid closed while driving.
- Never transport objects larger than those
fitting completely into the luggage area be­
cause the rear lid cannot be fully closed.
- If you absolutely must dr ive with the rear lid
open, observe the following notes to reduce
the risk of poisoning :
- C lose all windows,
- Close the s unroof*,
- Open all a ir outlets in the instrument pan-
el,
- Switc h off the air reci rculat ion,
- Set the fresh air fan to the highest speed.
A WARNING
-
Always make sure that the doo rs, all win­
dows, the sunroof * an d the rear lid are se­
curely closed and locked to red uce the risk of
i n jury when the veh icle is not being used.
- After closing the rear lid, always make sure
that it is properly closed and locked.
- Never leave your ve hicle unattended espe­
cially with the rear lid left open. A child
co uld crawl into the vehicle th rough the lug­
g age com partment an d close the rea r lid
be­
coming tr apped and unab le to ge t out . Be­
ing trapped in a vehicle can lead to ser ious
pe rsonal i nju ry.
- Never let c hild ren p lay in or around the vehi­
cle.
- Never let passengers ride in the luggage
compa rtment. Vehicle occupants mus t
al­
ways be p roperly restrained in one of the ve ­
hicle's seat ing pos itions.
(D Tips
- Air circul ation helps to reduce w indow fog­
ging . Stale ai r escapes to the o uts ide
t h roug h vents in the trim panel. Be sure to
keep these slots free and open.

Airbag system
-Never hold the steering wheel at the 12
o'clock position or with your hands any­
where inside the steering wheel or on the
steering wheel hub. Holding the steering
wheel the wrong way increases the risk of
severe injury to the arms, hands, and head if
the driver airbag deploys.
,& WARNING
Objects between you and the airbag will in­
crease the risk of injury in a crash by interfer­
ing with the way the airbag unfolds and/or by
being pushed into you as the airbag inflates.
- Always make sure nothing is in the front air-
bag deployment zone that could be struck
by the airbag when it inflates.
-
- Objects in the zone of a deploying airbag
can become projectiles when the airbag de­
ploys and cause serious personal injury.
- Never hold things in your hands or on your
lap when the vehicle is in use.
- Never place accessories or other objects
(such as cup holders, telephone brackets,
note pads, navigation systems, or things
that are large, heavy, or bulky) on the doors;
never attach then to the doors or the wind­
shield; never place them over or near or at­
tach them to the area marked ,,AIRBAG" on
the steering wheel, instrument panel or the
seat backrests; never place them between
these areas and you or any other person in
the vehicle.
- Never attach objects to the windshield
above the passenger front airbag, such as
accessory GPS navigation units or music
players. Such objects could cause serious in­
jury in a collision, especially when the air­ bags inflate.
- Never recline the front passenger seat to transport objects. Items can also move into
the deployment area of the side airbags or
the front airbag during breaking or in a sud­
den maneuver. Objects near the airbags can
fly dangerously through the passenger com­ partment and cause injury, particularly
when the seat is reclined and the airbags in­
flate.
276
,& WARNING
, -
A person on the front passenger seat, espe­
cially infants and small children, will receive
serious injuries and can even be killed by be­ ing too close to the airbag when it inflates .
- Although the Advanced Airbag System in your vehicle is designed to turn off the front passenger airbag if an infant or a small child
is on the front passenger seat, nobody can
absolutely guarantee that deployment un­
der these special conditions is impossible in
all conceivable situations that may happen
during the useful life of your vehicle.
- The Advanced Airbag System can deploy in accordance with the
,.low risk" option for 3-
and 6-year-old children under the U.S. Fed­
eral Standard if a child with electrical capac­
itance greater than the combined capaci­
tance of a typical one-year old infant re­
strained in one of the forward facing or rear­
ward-facing child seats with which your ve­ hicle was certified is on the front passenger
seat and the other conditions for airbag de­
ployment are met.
- Accident statistics have shown that children
are generally safer in the rear seat area than
in the front seating position.
- For their own safety, all children, especially
12 years and younger, should always ride in
the back properly restrained for their age
and size.
Advanced front airbag system
Your vehicle is equipped with a front Advanced
Airbag System in compliance with United States
Federal Motor Vehicle Safety Standard (FMVSS)
208, as well as Canada Motor Vehicle Safety
Standard (CMVSS) 208 as applicable at the time
your vehicle was manufactured .
-
The front Advanced Airbag System supplements
the safety belts to provide additional protection
for the driver's and front passenger's heads and upper bodies in frontal crashes. The airbags in­
flate only in frontal impacts when the vehicle de-
celeration is high enough.

Convertible child safety seats
Properly used convertible child safety seats can
help protect toddlers and children over age one
who weigh between
20 and 40 lbs. (9 and 18 kg)
in a crash.
Fig. 250 Schematic overv iew: insta llatio n of the attach­
ments applicab le to a LATCH seat
Fig. 251 Schematic overv iew: installat ion of the seat using
the vehicle 's safety belt system
.. When using the vehicle safety belt to install a
child safety seat, you must first activate the
convertible locking retractor on the safety belt
to prevent the child safety seat from moving
Q page 306 or install the seat us ing the LATC H
attachments .
.. Push the child safety seat down with your fu ll
weight to get the safety belt really tight so that
the seat cannot move forward o r sideways
more than one inch (2.5 cm)
Q page 306.
.. If the child safety seat is equipped with a tether
strap, attach it to the tether anchors
Q page 312.
.. Secure unused safety belts on the rear seat
Qpage 301 .
A toddler or child is usually too large for an in­
fant restraint if it is more than one year old and
weighs more than 20 lbs. (9 kg).
Child safety
To ddlers and children who are older than one
year up to about 4 years old and weigh more than
20 lbs. (9 kg) up to 40 lbs. (18 kg) must always
be properly restrained in a child safety seat certi­
fied for their size and weight
Q fig. 250 and
q fig . 251.
The airbag on the passenger side makes the front
seat a potentially dangerous place for a child to
ride. The front seat is not the safest place for a
child in a forward-facing child safety seat. It is a
very dangerous place for an infant or a larger
child in a rearward-facing seat .
_&. WARNING
Not using a child safety seat, us ing the wrong
child safety seat or improperly instal ling a
chi ld restraint increases the risk of serious
personal injury and death in a collision or oth ­
er emergency situation.
-Children on the front seat of any car, even
with Advanced Airbags, can be seriously in­
jured or even killed when an airbag inflates.
A child in a rearward-facing ch ild safety seat
installed on the front passenger seat will be
seriously injured and can be killed if the
front airbag inflates
-even with an Ad­
vanced Airbag System.
-The inflating airbag will hit the child safety
seat or infant carr ier with great force and
will smash the child safety seat and child
against the backrest, center armrest, door
or roof.
-Al ways install rear-fa cing child safety seats
on the rear seat .
-If you must insta ll a rearward facing child
safety seat on the front passenger seat be­
cause of excep tional circumstances and the
PASSENGER AIR BAG OFF '-I; light does not
come on and stay on, immediately insta ll
the rear-facing child safety seat in a rear
seating position and have the a irbag system
inspected by your Audi dealer .
-The rear side of the ch ild safety seat shou ld
be positioned as close as possible to the
backrest on the veh icle seat. Adjust or re­
move the rear seat head restraint if it is dif­
f icult to install the child seat with the head
