Stowing luggage
Loading the luggage compartment
All luggage and other objects must be prop erly stowed and secured in the luggage com
partment.
Fig . 184 Safe load pos ition ing: place heavy objects as
low and as far forward as possible.
Loose items in the luggage compartment can
shift suddenly, changing vehicle handling
characterist ics . Loose items can also increase
the r isk of serious personal injury in a sudden
vehicle maneuver or in a collision .
,. Distribute the load evenly in the luggage
compartment .
,. Always place and properly secure heavy
items in the luggage compartment as low
and as far forward as poss ible
¢fig. 184.
,. Secure luggage using the tie-downs provid
ed
¢ page 80.
,. Make sure that the rear seatback is securely
latched in place .
A WARNING
Improperly stored luggage or other items
can fly through the vehicle caus ing serious
personal inj ury in the event of hard brak
ing or an acc ident. To help reduce the r isk
of serious persona l injury:
- Always put objects, for example, luggage
or other heavy items in the luggage com
partment.
- Always secu re objects in the luggage
compartment us ing the tie-down eye lets
and suitable straps.
A WARNING
-Heavy loads wi ll influence the way your ve-
h icle ha ndles. To help reduce the risk of a
loss of control leading to serious personal
i njury:
-Always keep in mind when transporting
heavy objects, that a change in the cen
ter of gravity can also cause changes in
veh icle handling:
- Always distribute the load as evenly as
poss ible.
- Place heavy objects as far forward in
the luggage compartment as possible.
- Never exceed the Gross Axle We ight Rat
ing or the Gross Vehicle Weight Rating
specif ied on the safety compliance stick
er on the left door jamb. Exceed ing per
miss ible weight standards can cause the
veh icle to slide and handle differen tly.
- Please observe information on safe dr iv
ing
¢page 160.
A WARNING
-
To help prevent poisonous exhaust gas
from being drawn into the vehicle, a lways
keep the rear lid closed while driving.
- Never transport objects larger than those fitting comp letely into the luggage
area because the rear lid cannot be ful ly
closed.
- If you absolutely m ust dr ive wi th the rear
lid open, observe the following notes to
red uce the risk of poisoning:
- Close all windows,
- Close the Panoramic sliding sunroof *,
- Open all air outlets in the instrument pane l,
- Switc h off the air recirculat ion,
- Set the fresh air fan to the highest
speed.
A WARNING
Always make sure that the doors, all win
dows, the Panoramic sliding sunroof * and
the rear lid are securely closed and locked
-
Page 169 of 342

to reduce the risk of injury when the vehi
cle is not be ing used.
- After closing the rear lid, always make
sure that it is properly closed and locked.
- Never leave your vehicle unattended es
pecially with the rear lid left open . A
child could crawl into the vehicle through
the luggage compartment and close the
rear lid becoming trapped and unable to
get out . Be ing trapped in a vehicle can
lead to serious persona l injury .
- Never let children play in or around the vehicle .
- Never let passe ngers r ide in the luggage
compartment . Ve hicle occupants must
always be properly restrained in one of
the vehicle's seating positions.
(D Tips
- Air c irculation helps to reduce window
fogging . Sta le air escapes to the outside
th rough vents in the trim pane l. Be su re
to keep these slots free and open .
-The t ire pressure must correspond to the
load. The t ire pressur e is shown o n the
tire p ress ure label. The tire pressure la
bel is loc ated on the d river's s ide B-pi ll a r.
The t ire pressure label lists the recom
mended cold ti re inflat ion pressu res for
the vehicle at its maximum capacity

partment.
In a coll is ion, the l aws of phys ics mean that
even smalle r items that are loose in the vehi
cle will become heavy missiles that can cause
Dr iving S afel y 167
serious injury. Items in the ve hicle possess en
ergy which vary with vehicle speed and th e
weight o f the item . Vehicle speed is the most
s ignificant factor.
Fo r example, in a fronta l collision at a speed
of 30 mph (48 km/h), the forces acting on a
10 -lb (4.5 kg) object are about 20 t imes the
no rmal weight of the item. This means t hat
the weigh t of the item would sudden ly be
about 200 lbs. (90 kg) . You can imag ine the
i njur ies that a 200 lbs . (90 kg) item fly ing
fr eely th ro ugh the passenger compar tme nt
c ould cause in a co lli sion like this.
A WARNING
We ak, dam aged or imprope r str aps used
to secure items to tie -downs can fail dur
ing hard braking or in a collision and cause
serio us personal injury .
-Always use s uita ble mount ing stra ps and
properly secu re items to the tie-downs in
the l uggage compa rtme nt to he lp pre
vent items from shift ing or f ly ing fo r
ward as dangerous missiles .
-When the rea r seat backrest is folded
down, a lways use suitable mounting
straps and properly secure items to the
tie-downs in the luggage compartment
to hel p prevent items from fly ing for

,&_ WARNING
-Safety belts are the single most effective
means available to reduce the risk of se
rious injury and death in automobile acci
dents. For your protection and that of
your passengers, always correctly wear safety belts when the vehicle is moving .
- Failure to pay attention to the warning
light that come on, could lead to person
al injury.
Why safety belts?
Frontal collisions and the law of physics
Frontal crashes create very strong forces for
people riding in vehicles.
Fig. 186 Unbelted occupants in a ve hicle heading for a
wall
Fig. 187 The vehicle cras hes into the wall
The physical principles are simple. Both the
vehicle and the passengers possess energy
which varies with vehicle speed and body
weight . Engineers call this energy "kinetic en
ergy."
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.
Safety belts 1 71
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
using safety belts
¢fig. 186, they will keep
moving at the same speed the vehicle was
moving just before the crash, until something
stops them -here, the wall¢
fig. 187.
The same principles apply to people sitting in
a vehicle that is involved in a frontal collision.
Even at city speeds of 20 to 30 mph (30 to 50
km/h), the forces acting on the body can
reach one ton (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 colli
sion 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 col
lisions.

Child restraints on the front seat - some
important things to know
.. Be sure to read the important information
and heed the WARNINGS for important de
tails about chi ldren and Advanced Airbags
i=> page 200.
Even though your vehicle is equipped with an
Advanced Airbag System, make certain that
a ll chi ldren, especially those 12 years and
younger, always 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 r ide .
The front seat is not the safest place fo r a
chi ld in a fo rward-facing chi ld safety seat. It
can be a very dangerous place for an infan t or
a child in a rea rward-facing seat.
The Advanced Airbag System i n your veh icle
has been cert ified to comp ly with the require
men ts of United States Federa l Mo to r Veh icle
Safety Standard 208 as applicable at the time
your vehicle was manufactured.
The Standard requires the front a irbag on the
passenger side to be t urned off ("sup
p ressed") if a chi ld up to about one year of
age restrained in one of the rear -facing or for
ward -facing infant restraints listed i n Federal
Motor Vehicle Safety Standard 208 with wh ich
the Advanced Airbag System in your vehicle
was certified has been installed o n the front
passenger seat . For a listing of the child re
straints that were used to certify compliance
with the US Safety Sta ndard

T he PASSENGER AIR BAG OFF light comes on
whe n the contro l unit detects a tota l weight
on the front passenger seat that req uires the
front a irbag to be turned off.
If the total weight on the front passenger
seat is more than that of a typical 1 year-o ld
c h ild but less than the weight of a small
adult, the front airbag on the passenger side
can deploy (the
PASSENGER AIR BAG OFF
li ght does not come on). If the PASSENG ER
AIR BAG OFF
light does not come on, the
front a irbag on t he passenger side has not
been t urned off by the elect ronic con trol unit
and can deploy if the control unit senses an
impact that meets the cond itions stored in its
memory .
For exampl e, th e airb ag may deplo y if:
- a small ch ild that is heav ie r than a typical 1
year-old ch ild is o n the front passenger seat
(regard less of whether the child is in one of
the child safety seats listed
c> page 202), or
- a child who has outgrown child restraints is
on the front passenger seat.
If the front passenger airbag is turned off, the
PASSENGER AIR BAG OFF light comes on in
the instr ument cluster and stays on .
The front airbag on the passenger side may
not deploy (the PASSENGER AIR B AG OFF
light does not illum inate and stay lit) even if a

protection.
- An improperly insta lled child restraint
can interfere with the airbag as it de
ploys and seriously injure or even kill the
child -even with an Advanced Airbag
System .
- Always carefully follow the manufactur
er's instructions provided with the child
safety seat or carrier.
- Never place additional items on the seat
that can increase the total weight regis

There is a lot you need to know about the ai r
bags in your vehicle . We urge you to read t he
detailed information about airbags, safety
belts and child safety i n this and the other
chapters that make up the owner's literature. Please be sure to heed the WARNINGS -they
a re extremely important for your safety and
the safety of yo ur passengers, especially in
fants and small children.
_&. WARNING
N eve r rely on airbags alone for protec tion.
- Even w hen they deploy, airbags provide
only s uppleme ntal pro tect ion .
- Airbag work most effective ly when used

conditions is impossible in all conceiva
ble situations that may happen during
the useful life of your vehicle.
- The Advanced Airbag System can deploy
in accordance with the "low risk" option
under the U.S. Federal Standard if a child
that is heavier than the typical one-year
old child is on the front passenger seat
and the other conditions for airbag de
ployment are met.
-Accident statistics have shown that chil
dren are generally safer in the rear seat
area than in the front seating position.
- For their own safety, all children, espe
cially 12 years and younger, should al
ways 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
208 as applicable at the time your vehicle was
manufactured.
The front Advanced Airbag System supple ments the safety belts to provide additional
protection for the driver's and front passeng
er's heads and upper bodies in frontal crashes .
The airbags inflate only in frontal impacts
when the vehicle deceleration is high enough.
The front Advanced Airbag System for the
front seat occupants is not a substitute for
your safety belts. Rather, it is part of the over
all occupant restraint system in your vehicle.
Always remember that the airbag system can
only help to protect you, if you are sitting up
right , wearing your safety belt and wearing it
properly. This is why you and your passengers
must always be properly restrained, not just
because the law requires you to be.
The Advanced Airbag System in your vehicle has been certified to meet the "low risk" re
quirements for 3 and 6 year-old children on
the passenger side and very small adults on
the driver side. The low risk deployment crite
ria are intended to help reduce the risk of in- jury through interaction with the front airbag
that can occur, for example, by being too close to the steering wheel and instrument
panel when the airbag inflates.
In addition, the system has been certified to
comply with the "suppression" requirements
of the Safety Standard, to turn off the front
airbag for infants 12 months old and younger
who are restrained on the front passenger
seat in child restraints that are listed in the Standard
~ page 202, Child restraints and
Advanced Airbags .
"Suppression" requires the front airbag on the
passenger side to be turned off if:
- a child up to about one year of age is re
strained on the front passenger seat in one
of the rear-facing or forward-facing infant
restraints listed in Federal Motor Vehicle
Safety Standard 208 with which the Ad
vanced Airbag System in your vehicle was
certified. For a listing of the child restraints
that were used to certify your vehicle's com
pliance with the US Safety Standard
~page 202,
-weight less than a threshold level stored in
the control unit is detected on the front pas
senger seat.
When a person is detected on the front pas senger seat, weighing more than the total
weight of a child that is about 1 year old re
strained in one of the rear-facing or forward
facing infant restraints (listed in Federal Mo
tor Vehicle Safety Standard 208 with which
the Advanced Airbag System in your vehicle
was certified), the front airbag on the passen ger side may or may not deploy.
The
PASSENGER AIR BAG OFF light comes on
when the electronic control unit detects a to
tal weight on the front passenger seat that re quires the front airbag to be turned off. If the
PASSENGER AIR BAG OFF light does not
come on, the front airbag on the passenger
side has not been turned off by the control
unit and can deploy if the control unit senses
an impact that meets the conditions stored in
its memory.
ll-
Page 187 of 342

If the total weight on the front passenger
seat is more than that of a typical 1 year -old,
but less than the weight of a small adult, the
front airbag on the passenger side may deploy (the
P ASS ENGER AIR B AG OFF light does not
come on).
For example, th e airbag may depl oy if:
-a small child that is heavier than a typical 1
year-o ld child is on the front passenger seat
(regardless of whether the child is in one of
the chi ld safety seats listed
<=) page 202),
-a chi ld who has outgrown child restraints is
on the front passenger seat.
I f the front passenger airbag is turned
off, the
PA SSENGER AIR B AG OFF light in the center
of the instrument panel wi ll come on and stay
on.
The front a irbag on the passenger side may
not deploy (the PA SSENG ER AIR BAG O FF
light does not ill uminate and stay lit) if:
- a small adu lt or teenager is on the front pas
senger seat
- a passenger who is not sitt ing upright w ith
their back against a non-reclined backrest
with their feet on the vehicle floo r in front
of the seat is on the front passenge r seat .
If the front passenger airbag deploys, the
Federal Standard requires the a irbag to meet
the " low risk" deployment cr iteria to help re
duce the risk of inju ry through interaction
with the airbag. "Low risk" deployment occurs in those crashes that take place at lower de
celerations as defined in the electronic control
un it.
<=) page 190
Al ways rememb er: Even tho ugh your vehicle
is equipped with Advanced Airbags, the safest
p lace for children is properly restrained on the
back seat. Please be sure to read the impor
tant information in the sect ions that follow
and be sure to heed all of the WARNINGS.
A WARNING
To reduce the risk of injury when an airbag inflates, a lways wear safety belts prope rly.
A irbag system 185
-If you are unrestrained, leaning forward,
sitt ing s ideways or out of pos ition in any
way, your risk of injury is much higher.
- You will a lso receive serious injuries and
could even be killed if you are up aga inst
the airbag or too close to it when it in
flates -even w ith an Advanced A irbag
<=)page 179.
A WARNING
-
A child in a rearward-fac ing ch ild safety
seat installed on the front passenger seat
will be ser ious ly injured and can be killed if
the front airbag inflates -even with an Ad
vanced A irbag System.
- Al tho ugh the Advanced Airbag System in
your veh icle is designed to turn
off the
front airbag when a rearward -facing
child restraint has been insta lled on the
front passenger seat, nobody can abso
lutely guarantee that dep loyment is im
possible in all conceivable s ituations that
may happen dur ing the usefu l life of your
veh icle.
- The inflating airbag will h it the ch ild
safety seat or infant carrier with great
force and will smash the child safety seat
and child against the bac krest, center
armrest, doo r, or roof.
- Always install rearward-facing chi ld re
straints on the rear seat.
- If you must install a rearwa rd fac ing
child safety seat on the fro nt passenger
seat because of exceptiona l circumstan
ces and the
PASSENGER AIR BAG OFF
light does not come on and s tay on, im
mediately insta ll the rear-facing ch ild

Advanced Airbag System components
The front passenger seat in your vehicle has a lot of very important parts of the Advanced
Airbag System in it. These parts include the
weight-sens ing mat, sensors, wiring, brack
ets, and more . The fu nction of the system in
the front passenger seat is checked by the
e lectronic control u nit when the ignit ion is on.
The control unit mo nitors the Advanced Air
bag Sys tem and turns the airbag indicator
light on when a ma lfunction in the system
components is detected . The function of the
ai rbag ind icator light is described in greater
detai l below. Because the front passenger
seat contains important parts of the Ad
vanced A irbag System, you must take care to
prevent it from be ing damaged . Damage to
the seat may prevent the Advanced A irbag for
the front passenger seat from doing its job in
a cra sh .
The front Advanced Airbag System
consists of the following:
- Crash senso rs in the front of the veh icle that
measu re ve hicle ac celera tion/de ce le ra ti on
to provide info rm ation to the Advanced Air
bag System abo ut the severity of the crash . -
An elect ronic contro l unit, with integrated
crash sensors for front and side impacts .
The control un it "decides" whether to fi re
the front a irbags based on the informat ion
received from the crash sensors. The contro l
un it also "decides" whether the safety belt
prete nsioners shou ld be act ivated .
- An Advanced A irbag w ith gas generator for
the dr iver inside the stee ring wheel hub .
- An Advanced A irbag w ith gas generator in
side the instrument panel for the front pas
senge r.
- A we ight-sensing mat under the up ho lstery
padding of the front passenger seat cushion
that measures the total weight on the seat .
The informat io n registe red is sent continu

-Improper repair or disassembly of the
front passenger and driver seat will pre
vent the Advanced Airbag System from
functioning properly .
- Repairs to the front passenger seat must
be performed by qualified and properly
trained workshop personnel.
- Never remove the front passenger or
dr iver seat from the veh icle .
- Never remove the upholstery from the
front passenger seat .
- Never disassemble or remove parts from
the seat or disconnect wires from it.
- Never carry sharp objects in your pockets
or place them on the seat. If the weight
sensing mat in the passenger seat is
punctured it cannot work properly.
- Never carry things on your lap or carry
objects on the passenger seat . Such
items can increase the weight registered
by the weight-sens ing mat and send the
wrong info rmation to the airbag control
unit.
- Never store items under the front pas
senger seat. Parts of the Advanced Ai r
bag System under the passenger seat
cou ld be damaged, preventing them and
the airbag system from working proper
ly .
- Never place seat covers or replacement
upholstery that have not been specifical
ly approved by A udi on the front seats.
- Seat covers can prevent the Advanced
Airbag System from recognizing child re
straints or occupants on the front pas
senger seat and prevent the side airbag in the seat backrest from deploy ing prop
erly.
- Never use cush ions, pillows, blankets or
similar items on the front passenger
seat . The add itional padd ing will prevent
the weight-sens ing mat in the seat from
accu rately reg iste ring the ch ild restra int
or person on the seat and prevent the
Advanced Airbag System from function ing properly .
-If you must use a child restra int on the
front passenger seat and the chi ld re-

How the Advanced Airbag System
components work together
The front Advanced Airbag System and the
s ide airbags supp lement the protection of
fered by the front three-point safety belts
with pretensioners and load limiters and the
adjustable head rest raints to help reduce the
risk of inj ury in a wide range of accident and
c rash situations. Be s ure to read the impor
tant information about safety and heed the
WARNINGS in this chapter.
Deployment of the Adv a need A irbag System
and the activation of the safety belt preten
sioners depend on the deceleration measured
by the crash sensors and registered by the
electronic control unit. Crash severity depends
on speed and deceleration as we ll as the mass
and stiffness of the veh icle or object involved
in the crash .
When the e lectronic control unit registers a
low severity crash and the safety belt is being
used, the airbag will not deploy. If the safety
belt is not being used, the first stage deploys,
followed by the second stage after a much lat er t ime in the crash sequence.
If the electron ic control unit registers a crash
of medium severity , the first stage of the air
bag deploys followed by the second stage at a
much later time in the crash sequence -re
gardless of whether the safety belt is be ing
u sed or not . In higher sever ity crashes as reg
