-The tire pressure must correspond to the
load. The tire pressure label lists the recom­
mended cold tire inflation pressures for the
vehicle at its maximum capacity weight and
the tires that were on your vehicle at the
time it was manufactured. For recommend­
ed tire pressures for normal load condi­
tions, please see chapter
c:> page 345.
Tie-downs
The luggage compartment is equipped with four
tie-downs to secure luggage and other items .
Use the tie-downs to secure your cargo properly
c:> page 259, Loading the luggage compartment.
In a collision, the laws of physics mean that even
smaller items that are loose in the vehicle will
become heavy missiles that can cause serious in­
jury. Items in the vehicle possess energy which
vary with vehicle speed and the weight of the
item . Vehicle speed is the most significant factor .
For example, in a frontal collision at a speed of
30 mph (48 km/h), the forces acting on a 10 -lb
(4 .5 kg) object are about 20 times the normal
weight of the item . This means that the weight
of the item would suddenly be about
200 lbs . (90 kg). You can imagine the injuries
that a 200 lbs. (90 kg) item flying free ly through
the passenger compartment could cause in a col ­
lision like this.
A WARNING
Weak, damaged or improper straps used to
secure items to tie-downs can fail during hard braking or in a collision and cause serious per­
sonal injury.
- Always use suitable mounting straps and
properly secure items to the tie-downs in
the luggage compartment to help prevent
items from shifting or flying forward as dan­
gerous missiles .
-When the rear seat backrest is folded down,
always use suitable mounting straps and
properly secure items to the tie-downs in
the luggage compartment to help prevent
items from flying forward as dangerous
missiles into the passenger compartment .
-
Driving safety
-Never attach a child safety seat tether strap
to a tie-down.

Safety belts
Why use safety belts?
Frontal collisions and the law of physics
Frontal crashes create very strong forces for peo­
ple riding in vehicles .
Fig. 228 Unbelted occupants in a veh icle headi ng fo r a wall
Fig. 229 T he vehicle c rashes into the wall
The physical principles are simple. Both the vehi­
cle and the passengers possess energy which var­ ies w ith vehicle speed and body weight . Engi­
neers call this energy "k inetic energy."
The higher the speed of the vehicle and the
greater the vehicle's weight, the more energy
that has to be "absorbed" in the crash.
Vehicle speed is the most significant factor .
If
the speed doubles from 15 to 30 mph (25 to 50
km/h), the energy increases 4 times!
Because the passengers of this vehicle are not us­
ing safety
belts ~ fig. 228, they will keep moving
at the same speed the vehicle was moving just
before the crash, unti l something stops them -
here, the
wall ~ fig. 229.
The same principles apply to people sitting in a
vehicle that is involved in a frontal collision . Even
at c ity speeds of 20 to 30 mph (30 to 50 km/h),
the forces acting on the body can reach one ton
264 (2,000 lbs.
or 1,000 kg) or more . At greater
speeds, these forces are even higher.
People who do not use safety belts are also not
attached to their vehicle. In a frontal collision
they will also keep moving forward at the speed
their vehicle was travelling just before the crash.
Of course, the laws of physics don't just apply to
frontal collisions, they determine what happens in all kinds of accidents and collisions .
What happens to occupants not wearing
safety belts?
In crashes unbelted occupants cannot stop
themselves from flying forward and being in­
jured or killed . Always wear your safety belts!
Fig. 230 A drive r not wea ring a safety belt is vio len tly
t hrow n fo rward
Fig. 231 A rear passe nge r not wear ing a sa fety belt will f ly
forward an d str ike the driver
Unbelted occupants are not able to res ist the tre­
mendous forces of impact by holding tight or
bracing themselves. Without the benefit of safe­
ty restraint systems, the unrestra ined occupant
will slam violently into the steering wheel, in­
strument panel, windshield, or whatever e lse is
in the
way ~ fig. 230. T his impact with the vehi ­
cle interior has all the energy they had just be-
fore the crash.

about children and Advanced Airbags
¢page 295 .
Even though yo ur vehicle is equipped with an Ad­
vanced Airbag System, make certain that all chil­
dren, especially those 12 years and younger,
a l­
ways ride in the back seat properly restrained for
their age and size. 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 can be a very dangerous place for
a n infant or a child in a rearward-fac ing seat.
The Advanced Airbag System in your veh icle has
been certified to comply with the requirements
of United States Federal Motor Vehicle Safety
Standa rd (FMVSS) 208, as well as Canada Motor
Veh icle Safety Standa rd (CMVSS) 208 as applica­
b le a t the time your veh icle was m an ufact ured.
Accord ing to requirements, the front Advanced
Airbag System on the passenger side has been
certified for "suppression" for infants of about 12 month old and younger and for "low risk
de­
ployment" for children aged 3 to 6 years old (as
defined in the standard) .
The
PASSENGER AIR BAG O FF ~ ; light in the
headliner tells you when the front Advanced Air­
bag on the passenger side has been turned off by
the electronic control unit.
Each time yo u turn on the ignition, the

for a few seconds and:
- PASSENGER AIR BAG OFF ~; will come on if
the front passenger seat is not occupied
- PASSENGER AIR BAG OFF ~; will come on if
the e lectrica l capacitance measured by the
ca­
pacitive passenger detection system for the
front passenger seat equa ls the comb ined

pacitance of an infant up to about one year of
age and one of the rearward-facing or forward ­
facing child restra ints listed i n Federa l Moto r

The PASSENGER AIR BAG OFF ~; light comes on
when e lectrical capacitance registered on the
front passenger seat is equal to or less than the
combined capacitance of a typical 1 year-old

facing child restrai nts listed in Federal Motor Ve­
hicle Safety Standard ( FMVSS) 208 with wh ich
the Advan ced Airbag System in yo ur vehicle was
ce rtified.
If the total electr ical capacitance reg istered on
t h e front passenger seat is mo re than that of a
typ ical 1 year -old ch ild but less than the weight
of a sm all adult, the front air bag on the passen­
ger side can deploy (the
PASSENGER AIR BAG

If the
PASSENGER AIR BAG OFF ~; light does
not come on, the front airbag on the p assenger
s ide has not been turned off by the electronic
contro l unit and can deploy if the contro l unit
senses an impact that meets the conditions stor­
ed in its memory.
For example , the airbag may deploy if :
-a small c hild that is heav ier than a typ ica l 1

The front Advanced Airbag System for the front
seat occupants is not a substitute for your safety be lts. Rather, it is part of the overa ll occupant re ­
straint system in your vehicle. A lways remember
that the airbag system can on ly help to protect
you, if you are sitting upr ight, wear ing your safe­
ty belt and wear ing it properly. This is why you
and your passengers must always be properly re­
stra ined, not just because the law requ ires you to
be.
The Advanced Airbag System in your ve hicle has
been certified to meet the
"low r isk" require­
ments for 3 and 6 yea r-old children o n the pas­
senger side and very sma ll adults on the drive r
side . The low r isk dep loyment cr iteria are intend­
ed to help reduce the risk of injury through inter­
action with the front airbag that can occur, for
examp le, by being too close to the steering wheel
and instrument pane l when the airbag inflates.
I n addition, the system has been certified to
comp ly with the "supp ression" requirements of
the Safety Standard, to turn off the front a irbag
for infants 12 months old and younger who are
restrained on the front passenger seat in child re­
stra ints that are listed in the Standard
c::> page 297, Child restraints and Advanced Air­
bags.
"Suppress ion" requ ires the front a irbag on the
passenger side to be turned off if:
- a ch ild up to about one year of age is restrained
on the front passenger seat in one of the rear­
facing or forward-fac ing infant restra ints listed
in Federal Motor Vehicle Safety Standard 208
with wh ich the Advanced Airbag System in your
vehicle was ce rt ified. For a listi ng of the ch ild
restra ints tha t were used to certify your veh i­
cl e's compl iance with the US Safety St andard
c::> page 297,
- When a person is dete cted on the front passen­
ger seat that has an electrical capacitance that
is more than the tota l electrical capac itance of
a ch ild that is about 1 year old restrained in one
of the rear-facing or forward-facing infant re­
straints (listed in Federal Motor Vehicle Safety
Standard 208 w ith which the Advanced A irbag
System in your veh icle was certified), the front
Airb ag sys tem
airbag on the passenger side may or may not
dep loy.
T he
PASSENGER AIR BAG OFF ~; ligh t comes on
whe n the elect ronic con trol uni t detects a tota l
electrical capacitance on the front passenger seat
that requires the front airbag to be turned off. If
the
PASSENGER AIR BAG OF F~; light does not
come on, the front airbag on the passenger side
has not been turned
off by the contro l unit and
can deploy if the contro l unit senses a n impact
that meets the cond itions stored in its memory.
If the total e lectr ica l capacitance reg istered on
the front passenger seat is more than that of a
typ ical 1 year-old, b ut less than the weight of a
small ad ult, the front a irbag on the passenger
s ide may dep loy (the
PASSENGER AIR BAG OFF
~; light does not come on).
For example, th e airbag may deploy if:
- a small ch ild that is heav ier than a typ ical 1
year-o ld child is on the front passenger seat
(regardless of whether the child is in one of the
child safety seats listed
c:> page 297),
- a child who has outgrown c hild restraints is on
the front passenger seat.
If the front passenger airbag is t urned
off, the
PASSENGER AIR BAG OFF ~; light in the head­
liner w ill come on and stay on.
If the front passenge r airbag deploys, the Feder­
al Standard requ ires the a irbag to meet the " low
risk" deployment criteria to help reduce the r isk
of inj ury through interaction with the airbag.
"Low risk" deployment occurs in those crashes
that take place at lower decelerations as defined
i n the electronic control unit .
c::>page 283
Always remember: Even though your vehicle is
equipped with Advanced Airbags, the safest place
for childre n is properly restrained on the back
seat. Please be sure to read the impor tant infor­
mation in the sec tions that fo llow and be sure to
heed all of the WARNINGS.

A WARNING
If the front airbag inflates, a ch ild without a
chi ld restraint, or in a rearward-facing child
safety seat, or in a forward-fac ing child re­
stra int that has not been properly insta lled
will be seriously injured and can be killed.
- Even though your vehicle is equipped with
an Advanced A irbag System, make certain
that all children , espec ially 12 years and
younge r, always ride on the back seat p rop­

Side curtain airbags
Description of side curtain airbags
The side curtain airbags can provide supplemen­
tal protection to properly restrained oc cupants.
Fig. 2 46 Sid e curta in airbags, driver 's side : locatio n
The side curtain airbags are located on both sides
of the interior above the front and rear side win­
dows
¢ fig. 246.
The side curtain airbags contain features that
provide ejection mitigation to help prevent vehi­
cle occupants or parts of their bodies from be ing
completely or part ially ejected from the vehicle
i nterior i n certa in side impacts and vehicle roll­
ove rs .
The side curtain airbag system supplements the
safety belts and can help to reduce the risk of in­
jury for occupants' heads and upper torso in a
side collision . The s ide curtain a irbag inflates in
s ide impacts and on ly when the veh icle ac celera­
tion registered by the control unit is high

Airbag syste m
seating position is not proper or upright or if
items are located in the area where the supp le­
mental side curtain airbag inflates. This applies
especially to
children ¢ page 295.
Although they are not a soft pillow, side curtain
airbags can "cushion" the impact and in this way
they can help to reduce the risk of in jury to the
head and the upper part of the body.
A fine dust may develop when the airbag deploys.
This is quite normal and does not mean there is a
f ire in the veh icle .
Important safety instructions on the side
curtain airbag system
Airbags are only supplemental restraints. Always
properly wear safety belts and ride in a proper
seating position.
There is a lot that yo u and your passengers must
know and do to help the safety be lts and airbags
do their job to provide supplemental protect ion.
A WARNING
Improperly wearing safety belts and improper
seating posit ions increase the risk of serious
personal inju ry and death whenever a vehicle
is being used.
- Never let occupants p lace any parts of the ir
bodies in the area from which the side cur­
ta in a irbag inflate.
- Always make sure that the side curtain air­
bags can inflate witho ut interferen ce.
- Use the built- in coat hooks on ly for light­
weight cloth ing. Neve r leave any heavy or
sharp-edged obje cts in t he pockets that may
in terfere w ith airbag deployment and can
ca use personal injury in a collision.
- Never use hangers to hang clothes on the
hoo ks.
- Only use factory-installed s un shades or, if
shades installed after the veh icle leaves the
factory, use only genuine Aud i sun shades.
- Never swing the sun viso rs ove r to the side
windows if things such as pens, ga rage door
openers, hands-free speakers, etc . are at­
tached to the sun visors. They co uld come
294
loose and cause serious injury if the side cu r­
tain airbag inflates.
- A deploying airbag inflates in a fraction of a
second and with great force.
- Never attach objects to the cover or in the
deployment zone of a side curtain airbag .
- The a irbag deployment zones must be kept
clear at all times. Make s ure there are no
objects, pets, o r other persons in the space
between any vehicle occupant and any air­
bag at any time.
- Do not attach any accessories to the doors.
A WARNING
- The a irbag system can deploy on ly once. If
the airbag has been triggered, the system
m ust be rep laced by an authorized A udi
dealer or qualified workshop .
- Always have work invo lv ing the side curtain
airbag system, remova l and installat ion of
the airbag components, or other repairs
pe rformed by a q ualified dealership. Other­
w ise the airbag system may not work cor­
rectly.
- Never attempt to mod ify any componen ts of
the airbag system in any way.

Child safety
Important information
Introduction
The rear seat is generally the safest place in a
collision .
The physical principles of what happens when
your vehicle is in a crash apply also to children
c:> page 264, What happens to occupants not
wearing safety belts? .
But unlike adults and
teenagers, their muscles and bones are not fully
developed. In many respects children are at
greater r isk of serious injury in crashes than
adults .
Because children's bodies are not fu lly devel­
oped, they require restraint systems especially
designed for their size, weight, and body struc­
ture. Many countries and all states of the United
States and provinces of Canada have laws requir­
ing the use of approved child restraint systems
for infants and small children .
I n a frontal crash at a speed of 20 -35 mph (30 -
56 km/h) the forces acting on a 13-pound (6 kg)
infant will be more than 20 times the weight of
the child . This means the weight of the chi ld
would suddenly be more than 260 pounds (120 kg) . Under these conditions, only an appro­
priate child restraint properly used can reduce
the r isk of serious injury . Child restra ints, like
adult safety belts, must be used properly to be
effect ive. Used improperly, they can inc rease the
risk of serious injury in an accident.
All ch ildren, especially those 12 years and young­
er must always ride in the back seat proper ly re­
stra ined for their age and size. If you must install
a child restraint on the front passenger seat in
exceptional circumstances, be sure to read and
heed the important information and warnings
c:> page 2 72. Infants and other children who are
properly restrained in an appropriate child re­
straint that is for their size and age can benefit
from the protection that supplemental side air­
bags provide in some kinds of crashes.
For more information please see information
provided by the:
Child safety
- National Highway Traffic Safety Administration
(NHTSA), currently at: http:/ /www.safe ­
rcar.gov (for the USA)
- Transport Canada Information Centre, current-
ly at: http://www.tc .gc.ca (for Canada)
Consult the child safety seat manufacturer's in­
structions in order to be sure the seat is right for
yo ur child's size
c:> page 299, Important safety
instructions for using child safety seats .
Please
be sure to read and heed all of the important in­
formation and WARNINGS about child safety,
Advanced Airbags, and the installation of child
restra ints in this chapter .
There is a lot you need to know about the Ad­
vanced Airbags in your vehicle and how they work
when infants and children in child restraints are on the front passenger seat . Because of the large
amount of important informat ion, we cannot re­
peat it all he re. We urge you to read the detailed
information in this owner 's manual about airbags
and the Advanced Airbag Sys tem in yo ur vehicle
and the very important information about trans­
porting children on the front passenger seat.
P lease be sure to heed the WARNINGS -they are
extremely important for your safety and the safe­
ty of your passengers, especially infants and
small children.
A WARNING
-- Accident statistics have shown that children
are generally safer in the rear seat area than
in the front seat ing pos ition. Always restrain
any child age 12 and under in the rear.
- All vehicle occupants and especially children
must be restrained properly whenever riding
in a vehicle. An unrestrained or imp roperly
rest rained child could be injured by striking
the interior or by being ejected from the ve­ hicle during a sudden maneuver or impact.
An unrestrained or improperly restrained
child is also at greater r isk of injury or death
through contact w ith an inflating a irbag.
-A suitable ch ild restraint properly installed
and used at one of the rear seating positions
provides the h ighest degree of protect ion
for infants and small children in most acci­
dent situat ions.
