driver's door?
The beeper sounds when:●The key is left in the ignition switch
*.
●The power mode
* is in ACCESSORY.
●The exterior lights are left on.
Why does the beeper
sound when I start driving?
The beeper sounds when:●Driver and/or front passenger are not wearing their seat belts.●The parking brake lever is not fully released.
Why do I hear a screeching

Is it possible to use
unleaded gasoline with a
Pump Octane Number
(PON) of 87 or higher on
this vehicle?
Unleaded gasoline with a pump octane number of 91 or higher
is recommended.
If premium unleaded gasoline with a PON of 91 or higher is not
available, you can temporarily use the gasoline with a PON of
87 or higher.
This will result in decreased engine performance, and can cause
occasional metallic knocking noise in the engine.

uuSeat Belts uAbout Your Seat Belts
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 and leaning reduce the effectiveness of the
belt and can increase the chance of serious injury in a crash.
• Never place the shoulder part of a lap/sh oulder seat belt under your arm or
behind your back. This could ca use 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, the
beeper will sound and the indicator will blink.
If the driver does not fasten the belt before
the beeper stops, the indicator will remain on.
The beeper will also periodically sound and
the indicator will blink while driving until the
driver's and front passenger’s seat belts are
fastened.

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 retractor by unfastening the
seat belt and allow the belt 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 b elt within six seconds after
the ignition switch is turned to ON
( w*1.
When no one is sitting in the front passenger's seat,
the indicator will not come on and the beeper will not
sound. The indicator also may not come on and the
beeper may not sound when the occupant is not
heavy enough to trigger the weight sensor. Such
occupants (e.g., infants and smaller children) should
be moved to the rear seat as a deploying front airbag
likely will injure or kill them. 2 Protecting Child Passengers P. 50

uuAirbags uAirbag System Components
Safe Driving
The front, 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.bTwo 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 .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.

monitors and can record information

or small child).

uuAirbags uTypes of Airbags
Safe Driving
Types of AirbagsYour 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) indicates 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 passenger. Both airbags are marked SRS AIRBAG.*1: Models with the smart entry system have an ENGINE START/STOP button instead of an
ignition switch.■
Housing Locations
1 Types of Airbags
The airbags can inflate whenever the ignition switch
is in ON
(w*1.
After an airbag inflates in a crash, you may see a
small amount of smoke. This is from the combustion
process of the inflator ma terial and is not harmful.
People with respiratory problems may experience
some temporary discomfort. If this occurs, get out of
the vehicle as soon as it is safe to do so.
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, depending 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.

■When side curtain airbags de ploy in a frontal collision
One or both side curtain airbags may inflate in a moderate-to-severe angled frontal
collision.
In this case, the side curtain airbags will deploy slightly after the front airbags.Airbag System IndicatorsIf a problem occurs in the airbag system, the SRS indicator will come on and a
message appears on the i-MID.

The indicator comes on for a few seconds,
then goes off. This tells you the system is
working properly.
If the indicator comes on at any other time, or does not come on at all, have the
system checked by a dealer as soon as possible. If you don't, your airbags and seat
belt tensioners may not work properly when they are needed.

Exhaust Gas HazardCarbon Monoxide GasThe 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 trunk open, airflow can pull exhaust gas into
the interior and create a hazardous condition. If you must drive with the trunk open, open both windows and set the heating and cooling system
*/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 heating and cooling system
*/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.

WARNING
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.
