87 or higher.
This will result in decreased en gine performance, and can cause
occasional metallic knocking noise in the engine.

Safe Driving
■Proper use of seat belts
Follow these guidelines for proper use:
• All occupants should sit upright, well back in the seat, and remain in that position
for the duration of the trip. Slouching an d leaning reduces the effectiveness of
the belt and can increase the chance of serious injury in a crash.
• Never place the shoulder part of a lap/shoulder seat belt under your arm or
behind your back. This could cause very serious injuries in a crash.
• Two people should never use the same seat belt. If they do, they could be very
seriously injured in a crash.
• Do not put any accessories on the seat belts. Devices intended to improve comfort
or reposition the shoulder part of a seat belt can reduce the protective capability
and increase the chance of serious injury in a crash.
Your vehicle monitors front seat belt use. If
the ignition switch is turned to ON
w*1
before the driver’s seat belt is fastened, a
beeper will sound and the indicator will blink.
If the driver does not fasten the belt before
the beeper stops, the in dicator will remain on.
The beeper will also periodically sound and
the indicator will blink while driving until the
driver’s and front passe nger’s seat belts are
fastened.
*1: Models with the keyless access system have an ENGINE START/STOP button
instead of an ignition switch.
■Seat Belt Reminder
1 About Your Seat Belts
If a rear seat passenger moves around and extends
the seat belt, the lockable retractor may activate. If
this happens, release the re tractor by unfastening the
seat belt and allow the be lt to retract completely.
Then refasten the belt.
1 Seat Belt Reminder
The indicator will also come on if a front passenger
does not fasten their seat belt within 6 seconds after
the ignition switch is turned to ON
(w*1.
When no one is sitting in the front passenger’s seat,
or a child or small adult is riding there, the indicator
will not come on.
This is because the weight sensors in the seat cannot
detect their presence.

uuAirbags uAirbag System Components
Safe Driving
The front, front side, and side curtain
airbags are deployed according to the
direction and severity of impact. 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.
bTwo side airbags, one for the driver and
one for a front passen ger. The airbags are
stored in the outer edges of the seat-
backs. Both are marked SIDE AIRBAG.
cTwo 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 .
dAn electronic control unit that continually
monitors and records information about
the sensors, the airbag activators, the
seat belt tensioners, and driver and front
passenger seat belt use when the ignition
switch is in ON
w*1.
eAutomatic front seat belt tensioners. The
driver’s and front passenger’s seat belts
incorporate sensors that detect whether
or not they are fastened.
The front seat belt tensioners also include
the e-pretensioners.
fA driver’s seat position sensor. If the seat
is too far forward, the airbag will inflate
with less force.
gWeight sensors in the front passenger’s
seat. The front passenger’s airbag will be
turned off if the weight on the seat is 65
lbs (29 kg) or less (the weight of an infant
or small child).

hImpact sensors that can detect a
moderate to severe front impact, side
impact, or if your vehicle is about to
rollover.

uuAirbags uTypes of Airbags
Safe Driving
Types of Airbags
Your vehicle is equipped with three types of airbags:
• Front airbags: Airbags in front of the driver ’s and front passenger’s seats.
• Side airbags: Airbags in the driver’s and front passenger’s seat-backs.
• Side curtain airbags: Airbags above the side windows.
Each is discussed in the following pages.
Front Airbags (SRS)
The front SRS airbags inflate in a moderate to severe frontal collision to help protect
the head and chest of the driver and/or front passenger.
SRS (Supplemental Restraint System) indica tes that the airbags are designed to
supplement seat belts, not replace them. Seat belts are the occupant’s primary
restraint system.
The front airbags are housed in the center of the steering wheel for the driver, and
in the dashboard for the front passenge r. Both airbags are marked SRS AIRBAG.
■Housing Locations
1Types of Airbags
The airbags can inflate whenever the ignition switch
is in ON
(w*1.
*1: Models with the keyless access system have an ENGINE START/STOP button instead of an ignition
switch.
1 Front Airbags (SRS)
Dual-Stage, Multiple-Threshold Front Airbags
(SRS)
Your vehicle is equipped with dual-stage, multiple-
threshold front airbags (SRS).
During a frontal crash severe enough to cause one or
both front airbags to deploy, the airbags can inflate
at different rates, dependi ng on the severity of the
crash, whether or not the seat belts are latched,
and/or other factors. Frontal airbags are designed to
supplement the seat belts to help reduce the
likelihood of head and chest injuries in frontal
crashes.

Safe Driving■When the side airbag off indicator comes on
This indicator comes on if the passenger’s side airbag has been turned off because
the passenger is too small to be sitting in the front seat, is slouching or not sitting
upright, or has leaned into the airbag’s deployment path.
Unless the passenger is a smaller statured adult or a child, the indicator should go
off when the passenger returns to a proper upright sitting position.

Exhaust Gas Hazard
Carbon Monoxide Gas
The engine exhaust from this vehicle contains carbon monoxide, a colorless,
odorless, and highly toxic gas. As long as you properly maintain your vehicle, carbon
monoxide gas will not get into the interior.
■Have the exhaust system inspected for leaks whenever
• The exhaust system is making an unusual noise.
• The exhaust system may have been damaged.
• The vehicle is raised for an oil change.
When you operate a vehicle with the tailgate open, airflow can pull exhaust gas into
the interior and create a hazardous conditio n. If you must drive with the tailgate
open, open all the windows and set the climate control system as shown below.
1. Select the fresh air mode.
2. Select the mode.
3. Set the fan speed to high.
4. Set the temperature control to a comfortable setting.
Adjust the climate control system in the same manner if you sit in your parked
vehicle with the engine running.
1 Carbon Monoxide Gas
An enclosed area such as a garage can quickly fill up
with carbon monoxide gas.
Do not run the engine with the garage door
closed.Even when the garage door is open, drive out
of the garage immediately after starting the engine.
3WARNING
Carbon monoxide gas is toxic.
Breathing it can cause unconsciousness and
even kill you.
Avoid any enclosed areas or activities that
expose you to carbon monoxide.
