Lap/Shoulder Belts
All seating positions in your vehicle are
equipped with lap/shoulder belts.
The seat belt webbing retractor will lock only
during very sudden stops or collisions. This
feature allows the shoulder part of the seat
belt to move freely with you under normal
conditions. However, in a collision the seat
belt will lock and reduce your risk of striking
the inside of the vehicle or being thrown out
of the vehicle.
WARNING!
• Relying on the air bags alone could lead
to more severe injuries in a collision. The
air bags work with your seat belt to
restrain you properly. In some collisions,
the air bags won’t deploy at all. Always
wear your seat belt even though you have
air bags.
• In a collision, you and your passengers
can suffer much greater injuries if you
are not properly buckled up. You can
strike the interior of your vehicle or other
passengers, or you can be thrown out of
WARNING!
the vehicle. Always be sure you and
others in your vehicle are buckled up
properly.
• It is dangerous to ride in a cargo area,
inside or outside of a vehicle. In a colli-
sion, people riding in these areas are
more likely to be seriously injured or
killed.
• Do not allow people to ride in any area of
your vehicle that is not equipped with
seats and seat belts.
• Be sure everyone in your vehicle is in a
seat and using a seat belt properly. Oc-
cupants, including the driver, should al-
ways wear their seat belts whether or not
an air bag is also provided at their seat-
ing position to minimize the risk of se-
vere injury or death in the event of a
crash.
• Wearing your seat belt incorrectly could
make your injuries in a collision much
worse. You might suffer internal injuries,
or you could even slide out of the seat
belt. Follow these instructions to wear
WARNING!
your seat belt safely and to keep your
passengers safe, too.
• Two people should never be belted into a
single seat belt. People belted together
can crash into one another in a collision,
hurting one another badly. Never use a
lap/shoulder belt or a lap belt for more
than one person, no matter what their
size.
WARNING!
• A lap belt worn too high can increase the
risk of injury in a collision. The seat belt
forces won’t be at the strong hip and
pelvic bones, but across your abdomen.
Always wear the lap part of your seat belt
as low as possible and keep it snug.
• A twisted seat belt may not protect you
properly. In a collision, it could even cut
into you. Be sure the seat belt is flat
against your body, without twists. If you
can’t straighten a seat belt in your ve-
hicle, take it to an authorized dealer
immediately and have it fixed.

latch plate and pull on the lap belt. A snug
seat belt reduces the risk of sliding under
the seat belt in a collision.
5. Position the shoulder belt across the
shoulder and chest with minimal, if any
slack so that it is comfortable and not
resting on your neck. The retractor will
withdraw any slack in the shoulder belt.
6. To release the seat belt, push the red
button on the buckle. The seat belt will
automatically retract to its stowed posi-
tion. If necessary, slide the latch plate
down the webbing to allow the seat belt to
retract fully.
Lap/Shoulder Belt Untwisting Procedure
Use the following procedure to untwist a
twisted lap/shoulder belt.
1. Position the latch plate as close as pos-
sible to the anchor point.2. At about 6 to 12 inches (15 to 30 cm)
above the latch plate, grasp and twist the
seat belt webbing 180 degrees to create a
fold that begins immediately above the
latch plate.
3. Slide the latch plate upward over the
folded webbing. The folded webbing must
enter the slot at the top of the latch plate.
4. Continue to slide the latch plate up until it
clears the folded webbing and the seat
belt is no longer twisted.
Adjustable Upper Shoulder Belt Anchorage
In the driver and outboard front passenger
seats, the top of the shoulder belt can be
adjusted upward or downward to position the
seat belt away from your neck. Push or
squeeze the anchorage button to release the
anchorage, and move it up or down to the
position that serves you best.As a guide, if you are shorter than average,
you will prefer the shoulder belt anchorage in
a lower position, and if you are taller than
average, you will prefer the shoulder belt
anchorage in a higher position. After you
release the anchorage button, try to move it
up or down to make sure that it is locked in
position.Adjustable Anchorage
SAFETY
112

NOTE:
The adjustable upper shoulder belt anchor-
age is equipped with an Easy Up feature. This
feature allows the shoulder belt anchorage to
be adjusted in the upward position without
pushing or squeezing the release button. To
verify the shoulder belt anchorage is latched,
pull downward on the shoulder belt anchor-
age until it is locked into position.
WARNING!
• Wearing your seat belt incorrectly could
make your injuries in a collision much
worse. You might suffer internal injuries,
or you could even slide out of the seat
belt. Follow these instructions to wear
your seat belt safely and to keep your
passengers safe, too.
• Position the shoulder belt across the
shoulder and chest with minimal, if any
slack so that it is comfortable and not
resting on your neck. The retractor will
withdraw any slack in the shoulder belt.
• Misadjustment of the seat belt could
reduce the effectiveness of the safety
belt in a crash.
WARNING!
• Always make all seat belt height adjust-
ments when the vehicle is stationary.
Seat Belts And Pregnant Women
Seat belts must be worn by all occupants
including pregnant women: the risk of injury
in the event of an accident is reduced for the
mother and the unborn child if they are wear-
ing a seat belt.Position the lap belt snug and low below the
abdomen and across the strong bones of the
hips. Place the shoulder belt across the chest
and away from the neck. Never place the
shoulder belt behind the back or under the
arm.
Seat Belt Pretensioner
The front outboard seat belt system is
equipped with pretensioning devices that are
designed to remove slack from the seat belt in
the event of a collision. These devices may
improve the performance of the seat belt by
removing slack from the seat belt early in a
collision. Pretensioners work for all size oc-
cupants, including those in child restraints.
NOTE:
These devices are not a substitute for proper
seat belt placement by the occupant. The
seat belt still must be worn snugly and posi-
tioned properly.
The pretensioners are triggered by the Occu-
pant Restraint Controller (ORC). Like the air
bags, the pretensioners are single use items.
A deployed pretensioner or a deployed air bag
must be replaced immediately.

Energy Management Feature
The front outboard seat belt system is
equipped with an Energy Management fea-
ture that may help further reduce the risk of
injury in the event of a collision. The seat belt
system has a retractor assembly that is de-
signed to release webbing in a controlled
manner.
Switchable Automatic Locking Retractors
(ALR) — (If Equipped)
The seat belts in the passenger seating posi-
tions may be equipped with a Switchable
Automatic Locking Retractor (ALR) which is
used to secure a child restraint system. For
additional information, refer to “Installing
Child Restraints Using The Vehicle Seat
Belt” under the “Child Restraints” section of
this manual. The figure below illustrates the
locking feature for each seating position.If the passenger seating position is equipped
with an ALR and is being used for normal
usage, only pull the seat belt webbing out far
enough to comfortably wrap around the occu-
pant’s mid-section so as to not activate the
ALR. If the ALR is activated, you will hear a
clicking sound as the seat belt retracts. Allow
the webbing to retract completely in this case
and then carefully pull out only the amount of
webbing necessary to comfortably wrap
around the occupant’s mid-section. Slide the
latch plate into the buckle until you hear a
"click."
In Automatic Locking Mode, the shoulder
belt is automatically pre-locked. The seat
belt will still retract to remove any slack inthe shoulder belt. Use the Automatic Locking
Mode anytime a child restraint is installed in
a seating position that has a seat belt with
this feature. Children 12 years old and under
should always be properly restrained in the
rear seat of a vehicle with a rear seat.
WARNING!
• NEVER use a rearward facing child re-
straint on a seat protected by an ACTIVE
AIRBAG in front of it, DEATH or SERI-
OUS INJURY to the CHILD can occur.
• Never install a rear-facing child restraint
in the front seat of a vehicle. Only use a
rear-facing child restraint in the rear
seat. If the vehicle does not have a rear
seat, do not transport a rear-facing child
restraint in that vehicle.
• A deploying passenger front air bag can
cause death or serious injury to a child
12 years or younger, including a child in
a rear-facing child restraint.ALR — Switchable Automatic Locking
Retractor

How To Engage The Automatic Locking Mode
1. Buckle the combination lap and shoulder
belt.
2. Grasp the shoulder portion and pull down-
ward until the entire seat belt is extracted.
3. Allow the seat belt to retract. As the seat
belt retracts, you will hear a clicking
sound. This indicates the seat belt is now
in the Automatic Locking Mode.
How To Disengage The Automatic Locking Mode
Unbuckle the combination lap/shoulder belt
and allow it to retract completely to disen-
gage the Automatic Locking Mode and acti-
vate the vehicle sensitive (emergency) lock-
ing mode.
WARNING!
• The seat belt assembly must be replaced
if the switchable Automatic Locking Re-
tractor (ALR) feature or any other seat
belt function is not working properly
when checked according to the proce-
dures in the Service Manual.
WARNING!
• Failure to replace the seat belt assembly
could increase the risk of injury in
collisions.
• Do not use the Automatic Locking Mode
to restrain occupants who are wearing
the seat belt or children who are using
booster seats. The locked mode is only
used to install rear-facing or forward-
facing child restraints that have a har-
ness for restraining the child.
Supplemental Active Head Restraints (AHR)
These head restraints are passive, deployable
components, and vehicles with this equip-
ment cannot be readily identified by any
markings, only through visual inspection of
the head restraint. The head restraint will be
split in two halves, with the front half being
soft foam and trim, the back half being deco-
rative plastic.How The Active Head Restraints (AHR) Work
The Occupant Restraint Controller (ORC) de-
termines whether the severity or type of rear
impact will require the Active Head Re-
straints (AHR) to deploy. If a rear impact
requires deployment, both the driver and
front passenger seat AHRs will be deployed.
When AHRs deploy during a rear impact, the
front half of the head restraint extends for-
ward to minimize the gap between the back of
the occupant’s head and the AHR. This sys-
tem is designed to help prevent or reduce the
extent of injuries to the driver and front pas-
senger in certain types of rear impacts.
NOTE:
The Active Head Restraints (AHR) may or
may not deploy in the event of a front or side
impact. However, if during a front impact, a
secondary rear impact occurs, the AHR may
deploy based on the severity and type of the
impact.
115

SABICs (if equipped with SABICs) may help
reduce the risk of head and other injuries to
front and rear seat outboard occupants in
certain side impacts, in addition to the injury
reduction potential provided by the seat belts
and body structure.
The SABIC deploys downward, covering the
side windows. An inflating SABIC pushes the
outside edge of the headliner out of the way
and covers the window. The SABICs inflatewith enough force to injure occupants if they
are not belted and seated properly, or if items
are positioned in the area where the SABICs
inflate. Children are at an even greater risk of
injury from a deploying air bag.
The SABICs (if equipped with SABICs) may
help reduce the risk of partial or complete
ejection of vehicle occupants through side
windows in certain side impact events.
WARNING!
• Do not mount equipment, or stack lug-
gage or other cargo up high enough to
block the deployment of the SABICs.
The trim covering above the side win-
dows where the SABIC and its deploy-
ment path are located should remain
free from any obstructions.
• In order for the SABICs to work as in-
tended, do not install any accessory
items in your vehicle which could alter
the roof. Do not add an aftermarket
sunroof to your vehicle. Do not add roof
racks that require permanent attach-
ments (bolts or screws) for installation
WARNING!
on the vehicle roof. Do not drill into the
roof of the vehicle for any reason.
Side Impacts
The Side Air Bags are designed to activate in
certain side impacts. The Occupant Restraint
Controller (ORC) determines whether the de-
ployment of the Side Air Bags in a particular
impact event is appropriate, based on the
severity and type of collision. The side impact
sensors aid the ORC in determining the ap-
propriate response to impact events. The
system is calibrated to deploy the Side Air
Bags on the impact side of the vehicle during
impacts that require Side Air Bag occupant
protection. In side impacts, the Side Air Bags
deploy independently; a left side impact de-
ploys the left Side Air Bags only and a right-
side impact deploys the right Side Air Bags
only. Vehicle damage by itself is not a good
indicator of whether or not Side Air Bags
should have deployed.
The Side Air Bags will not deploy in all side
collisions, including some collisions at cer-
tain angles, or some side collisions that do

Enhanced Accident Response System
In the event of an impact, if the communica-
tion network remains intact, and the power
remains intact, depending on the nature of
the event, the ORC will determine whether to
have the Enhanced Accident Response Sys-
tem perform the following functions:
• Cut off fuel to the engine (If Equipped)
• Cut off battery power to the electric motor
(If Equipped)
• Flash hazard lights as long as the battery
has power
• Turn on the interior lights, which remain on
as long as the battery has power or for 15
minutes from the intervention of the En-
hanced Accident Response System.
• Unlock the power door locks.
Your vehicle may also be designed to perform
any of these other functions in response to
the Enhanced Accident Response System:
• Turn off the Fuel Filter Heater, Turn off the
HVAC Blower Motor, Close the HVAC Circu-
lation Door• Cut off battery power to the:
– Engine
– Electric Motor (if equipped)
– Electric power steering
– Brake booster
– Electric park brake
– Automatic transmission gear selector
– Horn
– Front wiper
– Headlamp washer pump
NOTE:
After an accident, remember to cycle the
ignition to the STOP (OFF/LOCK) position
and remove the key from the ignition switch
to avoid draining the battery. Carefully check
the vehicle for fuel leaks in the engine com-
partment and on the ground near the engine
compartment and fuel tank before resetting
the system and starting the engine. If there
are no fuel leaks or damage to the vehicle
electrical devices (e.g. headlights) after an
accident, reset the system by following the
procedure described below. If you have any
doubt, contact an authorized dealer.
Enhanced Accident Response System Reset
Procedure
In order to reset the Enhanced Accident Re-
sponse System functions after an event, the
ignition switch must be changed from igni-
tion START or ON/RUN to ignition OFF. Care-
fully check the vehicle for fuel leaks in the
engine compartment and on the ground near
the engine compartment and fuel tank before
resetting the system and starting the engine.
Maintaining Your Air Bag System
WARNING!
• Modifications to any part of the air bag
system could cause it to fail when you
need it. You could be injured if the air
bag system is not there to protect you.
Do not modify the components or wiring,
including adding any kind of badges or
stickers to the steering wheel hub trim
cover or the upper passenger side of the
instrument panel. Do not modify the
front bumper, vehicle body structure, or
add aftermarket side steps or running
boards.

In Europe, children restraint systems are de-
fined by regulation ECE-R44, which divides
them into five weight groups:
Restraint Group Weight Group
Group 0 up to 10 kg
Group 0+ up to 13 kg
Group 1 9-18 kg
Group 2 15-25 kg
Group 3 22-36 kg
Check the label of your child restraint. All
approved child restraints must include type-
approval data and the control mark on its
label. The label must be permanently se-
cured to the child restraint system. You
should not remove this label from the child
restraint.
WARNING!
Extreme Hazard! Do not place a rear-
facing child restraint in front of an active
air bag. Refer to visor mounted labels for
information. Deployment of the air bag in
an accident could cause fatal injuries to
the baby regardless of the severity of the

collision. It is advisable to always carry
children in a child restraint system on the
rear seat, which is the most protected
position in the event of a collision.
“Universal” Child Restraint Systems
• The figures in the following sections are
examples of each type of universal child
restraint system. Typical installations are
shown. Always install your child restraint
system according to the child restraint
manufacturer’s instructions, which must
be included with this type of restraint sys-
tem.
• See the section “Installing Child Restraints
Using the Vehicle Seat Belt” for the steps
to properly lock the seat belt over the child
restraint.
• Child restraint systems with ISOFIX anchor-
ages are available for installing the child
restraint system to the vehicle without us-
ing the vehicle’s seat belts.
Group 0 And 0+
Safety experts recommend that children ride
rearward facing in the vehicle as long as
possible. Infants up to 13 kg must be re-
strained in a rear-facing seat like the child
seat shown in fig. A. This type of child re-
straint supports the child’s head and does not
induce stress on the neck in the event of
sudden decelerations or a crash.
The rear-facing child restraint is restrained by
the vehicle’s seat belts, as shown in fig. A.
The child seat restrains the child with its own
harness.

• IUF = Suitable for ISOFIX forward child
restraint systems of universal category ap-
proved for use in the mass group.
• X = ISOFIX position not suitable for ISOFIX
child restraint systems in this mass group
and/or this size class.
Always follow the directions of the child re-
straint manufacturer when installing your child
restraint. Not all child restraint systems will be
installed as described here. When using a Uni-
versal ISOFIX child restraint system, you can
only use approved child restraint systems with
the marking ECE R44 (release R44/03 or supe-
rior) “Universal ISOFIX”.
To Install An ISOFIX Child Restraint
If the selected seating position has a Switch-
able Automatic Locking Retractor (ALR) seat
belt, stow the seat belt, following the instruc-
tions below. See the section “Installing Child
Restraints Using the Vehicle Seat Belt” to
check what type of seat belt each seating
position has.1. Loosen the adjusters on the lower connec-
tors and on the tether strap of the child
seat so that you can more easily attach the
connectors to the vehicle anchorages.
2. Place the child seat between the lower
anchorages for that seating position. For
some second row seats, you may need to
recline the seat and / or raise the head
restraint (if adjustable) to get a better fit.
If the rear seat can be moved forward and
rearward in the vehicle, you may wish to
move it to its rear-most position to make
room for the child seat. You may also move
the front seat forward to allow more room
for the child seat.
3. Attach the connectors of the child re-
straint to the lower anchorages in the
selected seating position.
4. If the child restraint has a tether strap,
connect it to the top tether anchorage.
See the section “Installing Child Re-
straints Using the Top Tether Anchorage”
for directions to attach a tether anchor.5. Tighten all of the straps as you push the
child restraint rearward and downward
into the seat. Remove slack in the straps
according to the child restraint manufac-
turer’s instructions.
6. Test that the child restraint is installed
tightly by pulling back and forth on the
child seat at the belt path. It should not
move more than 25 mm in any direction.
WARNING!
• Improper installation of a child restraint
to the ISOFIX anchorages can lead to
failure of the restraint. The child could
be badly injured or killed. Follow the
child restraint manufacturer’s directions
exactly when installing an infant or child
restraint.
• Child restraint anchorages are designed
to withstand only those loads imposed
by correctly-fitted child restraints. Un-
der no circumstances are they to be used
for adult seat belts, harnesses, or for
attaching other items or equipment to
the vehicle.
137

WARNING!
• The top tether anchorages are not visible
until the gap panel is folded down. Do
not use the visible cargo tie down hooks,
located on the floor behind the seats, to
attach a child restraint tether anchor.
• An incorrectly anchored tether strap
could lead to increased head motion and
possible injury to the child. Use only the
anchorage position directly behind the
child seat to secure a child restraint top
tether strap.
• If your vehicle is equipped with a split
rear seat, make sure the tether strap
does not slip into the opening between
the seatbacks as you remove slack in the
strap.
How To Stow An Unused Switchable-ALR
(ALR) Seat Belt:
When using the ISOFIX attaching system to
install a child restraint, stow all ALR seat
belts that are not being used by other occu-
pants or being used to secure child restraints.
An unused belt could injure a child if they
play with it and accidentally lock the seat beltretractor. Before installing a child restraint
using the ISOFIX system, buckle the seat belt
behind the child restraint and out of the
child’s reach. If the buckled seat belt inter-
feres with the child restraint installation, in-
stead of buckling it behind the child re-
straint, route the seat belt through the child
restraint belt path and then buckle it. Do not
lock the seat belt. Remind all children in the
vehicle that the seat belts are not toys and
that they should not play with them.
Installing Child Restraints Using The Ve-
hicle Seat Belt
Child restraint systems are designed to be
secured in vehicle seats by lap belts or the lap
belt portion of a lap/shoulder belt.
WARNING!
• Improper installation or failure to prop-
erly secure a child restraint can lead to
failure of the restraint. The child could
be badly injured or killed.
• Follow the child restraint manufacturer’s
directions exactly when installing an in-
fant or child restraint.The seat belts in the rear passenger seating
positions are equipped with a Switchable
Automatic Locking Retractor (ALR) that is
designed to keep the lap portion of the seat
belt tight around the child restraint. The ALR
retractor can be “switched” into a locked
mode by pulling all of the webbing out of the
retractor and then letting the webbing retract
back into the retractor. If it is locked, the ALR
will make a clicking noise while the webbing
is pulled back into the retractor. Refer to the
“Automatic Locking Mode” description in
“Switchable Automatic Locking Retractors
(ALR)” under “Occupant Restraint Systems”
for additional information on ALR.
