Seat Belts
About Your Seat Belts
Seat belts are the single most effective safety device because they keep you
connected to the vehicle so that you can take advantage of many built-in safety
features. They also help keep you from be ing thrown against the inside of the
vehicle, against any passengers, or out of the vehicle. When worn properly, seat
belts also keep your body properly positioned in a crash so that you can take full
advantage of the additional protection provided by the airbags.
In addition, seat belts help protect you in almost every type of crash, including:
- frontal impacts
- side impacts
- rear impacts
- rollovers
■Lap/shoulder seat belts
All six or seven seating positions are equipped with lap/shoulder seat belts with
emergency locking retractors. In normal dr iving the retractor lets you move freely
while keeping some tension on the belt. During a collision or sudden stop the
retractor locks to restrain your body.
The front passenger’s, second row and third row seat belts also have a lockable
retractor for use with child seats.

1About Your Seat Belts
Seat belts cannot complete ly protect you in every
crash. But in most cases, seat belts can reduce your
risk of serious injury.
Most states and all Canadian provinces and territories
require you to wear seat belts.
If you extend the seat belt t oo quickly, it will lock in
place. If this happens, sli ghtly retract the seat belt,
then extend it slowly.
3WARNING
Not wearing a seat belt properly increases
the chance of serious injury or death in a
crash, even though your vehicle has
airbags.
Be sure you and your passengers always
wear seat belts and wear them properly.

uuSeat Belts uAbout Your Seat Belts
Safe DrivingThe front seats are equi pped with automatic
seat belt tensioners to enhance safety.
The tensioners automatically tighten the front
seat belts during a moderate-to-severe frontal
collision, sometimes even if the collision is not
severe enough to inflate the front airbags or
the driver’s knee airbag.
■Automatic Seat Belt Tensioners1 Automatic Seat Belt Tensioners
The seat belt tensioners can only operate once.
If a tensioner is activated, the SRS indicator will come
on. Have a dealer replace the tensioner and
thoroughly inspect the seat belt system as it may not
offer protection in a subsequent crash.
During a moderate-to-severe side impact, the
tensioner on that side of the vehicle also activates.

uuAirbags uAirbag System Components
Safe Driving
The front, driver’s knee, front side, and side
curtain airbags are deployed according to
the direction and severity of impact. Both
side curtain airbags are deployed in a
rollover. The airbag system includes:
aTwo SRS (Supplemental Restraint System)
front airbags. The driver’s airbag is stored
in the center of the steering wheel; the
front passenger’s airbag is stored in the
dashboard. Both are marked SRS
AIRBAG.
bDriver’s knee airbag. The knee airbag is
stored under the steering column. It is
marked SRS AIRBAG.
cTwo side airbags, one for the driver and
one for a front passenger. The airbags are
stored in the outer edges of the seat-
backs. Both are marked SIDE AIRBAG .
dTwo side curtain airbags, one for each
side of the vehicle. The airbags are stored
in the ceiling, above the side windows.
The front and rear pillars are marked
SIDE CURTAIN AIRBAG.
eAn electronic control unit that, when the
power mode is in ON, continually
monitors information about the various
impact sensors, seat and buckle sensors,
rollover sensor, airbag activators, seat
belt tensioners, and other vehicle
information. During a crash event the
unit can record such information.
fAutomatic front seat belt tensioners. In
addition, the driver’s and front
passenger’s seat belt buckles incorporate
sensors that detect whether or not the
belts are fastened.
gA driver’s seat position sensor. This
sensor determines the optimal force at
which the airbag will deploy in a crash.
hWeight sensors in the front passenger’s
seat. The front passenger’s airbag will be
turned off if the weight on the seat is
approximately 65 lbs (29 kg) or less (the
weight of an infant or small child).
iImpact sensors that can detect a
moderate-to-severe front or side impact.
jAn indicator on the dashboard that alerts
you that the front passenger’s front
airbag has been turned off.
kAn indicator on the instrument panel that
alerts you to a possib le problem with your
airbag system or seat belt tensioners.
lSafing Sensor
mA rollover sensor that can detect if your
vehicle is about to roll over and signal the
control unit to deploy both side curtain
airbags.

Safe Driving
■When front airbags should not deploy
Minor frontal crashes: Front airbags were designed to supplement seat belts and
help save lives, not to prevent minor scrape s, or even broken bones that might occur
during a less than moderate-to-severe frontal crash.
Side impacts: Front airbags can provide protection when a sudden deceleration
causes a driver or front passenger to move toward the front of the vehicle. Side
airbags and side curtain airbag s have been specifically designed to help reduce the
severity of injuries that can occur during a moderate-to-severe side impact which
can cause the driver or passenger to move toward the side of the vehicle.
Rear impacts: Head restraints and seat belts are your best protection during a rear
impact. Front airbags cannot provide any significant protection and are not designed
to deploy in such collisions.
Rollovers: In a rollover, your best form of protection is a seat belt or, if your vehicle
is equipped with a rollover sensor, both a se at belt and a side curtain airbag. Front
airbags, however, are not designed to deploy in a rollover as they would provide
little if any protection.
■When front airbags deploy with little or no visible damage
Because the airbag system senses sudden deceleration, a strong impact to the
vehicle framework or suspension might caus e one or more of the airbags to deploy.
Examples include running into a curb, the edge of a hole, or other low fixed object
that causes a sudden deceleration in th e vehicle chassis. Since the impact is
underneath the vehicle, damage may not be readily apparent.
■When front airbags may not deploy, even though exterior damage
appears severe
Since crushable body parts absorb crash energy during an impact, the amount of
visible damage does not always indicate proper airbag operation. In fact, some
collisions can result in severe damage but no airbag deployment because the airbags
would not have been needed or would not have provided protection even if they
had deployed.

uuAirbags uFront Airbags (SRS)
Safe DrivingThe airbags have advanced features to help reduce the likelihood of airbag related
injuries to smaller occupants. The driver’s advanced airbag system includes a
seat position sensor.
Based on information from this sensor and the
severity of the impact, the advanced airbag
system determines the optimal deployment of
the driver’s airbag.
The front passenger’s ad vanced airbag system
has weight sensors.
We advise against allowi ng a child age 12 or
under to ride in the front passenger’s seat.
However, if you do allow a child age 12 or
under to ride in the front passenger’s
seat , note that the system will automatically
turn off the front passenger’s airbag if the
sensors detect that the child is approximately
65 lbs (29 kg) or less.
■Advanced Airbags1 Advanced Airbags
If there is a problem with the driver’s seat position
sensor, the SRS indicator wi ll come on, and in the
event of a crash, the airbag will deploy (regardless of
the driver’s seating position) with a force
corresponding to the se verity of the impact.
For the advanced airbags to work properly:
•Do not spill any liquid on or under the seats.
•Do not put any object under the passenger’s seat.
•Make sure any objects are positioned properly on
the floor. Improperly pos itioned objects can
interfere with the advanced airbag sensors.
•All occupants should sit upr ight and wear their seat
belts properly.
•Do not cover the passenger ’s side dashboard with
a cloth, towel, cover, etc. 2Passenger Front Airbag Off Indicator

uuAirbags uSide Airbags
Safe Driving
Side Airbags
The side airbags help protect the torso and pelvis of the driver or a front passenger
during a moderate-to-severe side impact.
The side airbags are housed in the outside
edge of the driver’s and passenger’s seat-
backs.
Both are marked SIDE AIRBAG.
When the sensors detect a moderate-to-
severe side impact, the control unit signals the
side airbag on the impact side to immediately
inflate.
■Housing Locations
1 Side Airbags
Make sure you and your front seat passenger always
sit upright. Leaning into the path of a side airbag can
prevent the airbag from deploying properly and
increases your risk of serious injury.
Do not attach accessories on or near the side airbags.
They can interfere with the proper operation of the
airbags, or hurt someone if an airbag inflates.
Do not cover or replace the front seat-back covers
without consulting a dealer.
Improperly replac ing or covering front seat-back
covers can prevent your si de airbags from properly
deploying during a side impact.

uuAirbags uSide Airbags
Safe Driving
■When a side airbag deploys with little or no visible damage
Because the airbag system senses sudden acceleration, a strong impact to the side
of the vehicle’s framework can cause a side airbag to deploy. In such cases, there
may be little or no damage, but the side impact sensors detected a severe enough
impact to deploy the airbag.
■When a side airbag may not deploy, even though visible damage appears
severe
It is possible for a side airbag not to deploy during an impact that results in
apparently severe damage. This can occur when the point of impact was toward the
far front or rear of the vehicle, or when the vehicle’s crushable body parts absorbed
most of the crash energy. In either case , the side airbag would not have been
needed nor provided protection even if it had deployed.

uuAirbags uSide Curtain Airbags
Safe Driving
Side Curtain Airbags
The side curtain airbags help protect the heads of the driver and passengers in the
outer seating positions during a moderate-to -severe side impact. The side curtain
airbags equipped in th is vehicle are also designed to help reduce the likelihood of
partial and complete ejection of vehicle occupants through side windows in crashes,
particularly rollover crashes.
The side curtain airbags are located in the
ceiling above the side windows on both sides
of the vehicle.
The side curtain airbag is designed to deploy
in a rollover or a moderate-to-severe side
impact.
■Housing Locations
1Side Curtain Airbags
If the SRS control unit sens es that your vehicle is
about to rollover, it imme diately deploys both side
curtain airbags and activates both front seat belt
tensioners.
If the impact is on the passenger’s side, the
passenger’s side curtain airbag deploys even if there
are no occupants on that side of the vehicle.
To get the best protecti on from the side curtain
airbags, occupants should wear their seat belts
properly and sit upr ight and well back in their seats.
Do not attach any objects to the side windows or roof
pillars as they can interfere with the proper operation
of the side curtain airbags.

uuOperating the Switches Around the Steering Wheel uAuto High-Beam
Controls
Auto High-Beam
The front sensor camera detects the light sources ahead of the vehicle such as the
lights of a preceding or oncoming vehicle, or street lights. When you are driving at
night, the system automatically switches the headlights between low beam and high
beam depending on the situation.
When all of the following conditions have been met, the auto high-beam indicator
comes on and the auto high-beam is activated. •The power mode is in ON.
• The light switch is in AUTO.
• The lever is in the low beam position.
• The headlights have been automatically
activated.
• It is dark outside the vehicle.
If the auto high-beam indicator does not co me on even when all the conditions have
been met, carry out the following procedure and the indicator will come on.
• Pull the lever toward you for flashing the high beams then release it while driving.1Auto High-Beam
The auto high-beam system does not always operate
in every situation. This syst em is just for assisting the
driver. Always observe your surroundings and switch
the headlights between high beam and low beam
manually if necessary.
If you find the timing of beam changes inconvenient
for driving, change the headlight beams manually.
The range and the distance at which the camera can
recognize varies de pending on conditions
surrounding your vehicle.
Regarding the handling of the camera mounted to
the inside of the windshiel d, refer to the following.
2 Front Sensor Camera P. 487
For the auto high-beam to work properly:
•Do not place an object that reflects light on the
dashboard.
•Keep the windshield around the camera clean.
•When cleaning the windshield, be careful not to
apply the windshield cleans er to the camera lens.
•Do not attach an object, sticker or film to the area
around the camera.
•Do not touch the camera lens.
If the camera receives a st rong impact, or repairing of
the area near the camera is required, consult a dealer.
