Safe Driving

For Safe Driving

The following pages explain your vehicle’s safety features and how to use them 
properly. The safety precautions below are ones that we consider to be among the 
most important.

Important Safety Precautions

■

Always wear your seat belt

A seat belt is your best protection in all types of collisions. Airbags are designed to 
supplement seat belts, not replace them. So even though your vehicle is equipped 
with airbags, make sure you and your passengers always wear your seat belts, and 
wear them properly.

■

Restrain all children

Children ages 12 and under should ride properly restrained in a back seat, not the 
front seat. Infants and small children should be restrained in a child seat. Larger 
children should use a booster seat and a lap/shoulder seat belt until they can use the 
belt properly without a booster seat.

■

Be aware of airbag hazards

While airbags can save lives, they can cause serious or fatal injuries to occupants 
who sit too close to them, or are not properly restrained. Infants, young children, 
and short adults are at the greatest risk. Be sure to follow all instructions and 
warnings in this manual.

■

Don’t drink and drive

Alcohol and driving don’t mix. Even one drink can reduce your ability to respond to 
changing conditions, and your reaction time gets worse with every additional drink. 
So don’t drink and drive, and don’t let your friends drink and drive, either.

Important Safety Precautions

Some states, provinces and territories prohibit the use 
of cell phones other than hands-free devices by the 
driver while driving.

Important Safety Precautions

Safe Driving

■

Pay appropriate attention to the task of driving safely

Engaging in cell phone conversation or other activities that keep you from paying 
close attention to the road, other vehicles, and pedestrians could lead to a crash. 
Remember, situations can change quickly, and only you can decide when it is safe to 
divert some attention away from driving.

■

Control your speed

Excessive speed is a major factor in crash injuries and deaths. Generally, the higher 
the speed, the greater the risk, but serious injuries can also occur at lower speeds. 
Never drive faster than is safe for current conditions, regardless of the maximum 
speed posted.

■

Keep your vehicle in safe condition

Having a tire blowout or a mechanical failure can be extremely hazardous.
To reduce the possibility of such problems, check your tire pressures and condition 
frequently, and perform all regularly scheduled maintenance.

■

Do not leave children unattended in the vehicle

Children, pets and people needing assistance left unattended in the vehicle may be 
injured if they activate one or more of the vehicle controls. They may also cause the 
vehicle to move, resulting in a crash in which they and/or another person(s) can be 
injured or killed. Also, depending on the ambient temperature, the temperature of 
the interior may reach extreme levels, which can result in harm or death. Even if the 
climate control system is on, never leave them in the vehicle unattended as the 
climate control system can shut off at any time.

Your Vehicle’s Safety Features

The following checklist will help you take an active role in protecting yourself and 
your passengers.

1

Your Vehicle’s Safety Features

Your vehicle is equipped with many features that 
work together to help protect you and your 
passengers during a crash.

Some features do not require any action on your part. 
These include a strong steel framework that forms a 
safety cage around the passenger compartment, 
front and rear crush zones, a collapsible steering 
column, and tensioners that tighten the front seat 
belts in a sufficient crash.

However, you and your passengers cannot take full 
advantage of these features unless you remain seated 
in the correct position and always wear your seat 
belts. In fact, some safety features can contribute to 
injuries if they are not used properly.

Safety Checklist

Safe Driving

Safety Checklist

For the safety of you and your passengers, make a habit of checking these items 
each time before you drive.

•

After everyone has entered the vehicle, be sure all doors are closed and locked. 
Locking the doors helps prevent an occupant from being ejected and an outsider 
from unexpectedly opening a door.

2

Locking/Unlocking the Doors from the Inside

 P. 139

•

Adjust your seat to a position suitable for driving. Be sure the front seats are 
adjusted as far to the rear as possible while allowing the driver to control the 
vehicle. Sitting too close to a front airbag can result in serious or fatal injury in a 
crash.

2

Adjusting the Seats

 P. 175

•

Adjust head restraints to the proper position. Head restraints are most effective 
when the center of the head restraint aligns with the center of your head. Taller 
persons should adjust their head restraint to the highest position.

2

Adjusting the Front and Rear Outer Head Restraint Positions

 P. 178

•

Always wear your seat belt, and make sure you wear it properly. Confirm that any 
passengers are properly belted as well.

2

Fastening a Seat Belt

 P. 41

•

Protect children by using seat belts or child seats according to a child’s age, height 
and weight.

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 being 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 five seating positions are equipped with lap/shoulder seat belts with emergency 
locking retractors. In normal driving 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 and rear seat belts also have a lockable retractor for use with 
child seats.

About Your Seat Belts

Seat belts cannot completely 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 too quickly, it will lock in 
place. If this happens, slightly retract the seat belt, 
then extend it slowly.

3

WARNING

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.

About 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/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.

The seat belt system includes an indicator on 
the instrument panel to remind the driver or a 
front passenger or both to fasten their seat 
belts.
If you set the power mode to ON and a seat 
belt is not fastened, a beeper will sound and 
the indicator will blink. After a few seconds, 
the beeper will stop and the indicator will 
come on and remain illuminated until the seat 
belt is fastened.

The beeper will periodically sound and the 
indicator will blink while the vehicle is moving 
until the seat belt is fastened.

■

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 belt within six seconds after 
the power mode is set to ON.
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.

Safe Driving

The front seats are equipped 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.

Are the motor-powered pretensioners that 
start to retract the front seat belts when the 
CMBS

TM

, brake assist system, or VSA

®

 system 

is in operation. They may also activate when 
you steer the vehicle hard, or the vehicle is 
impacted. After being retracted, the seat belts 
are slackened to their original positions.
As convenience features, the e-pretensioners 
slightly retract the seat belts when you latch 
the seat belt buckle, depress the brake pedal 
more aggressively than you normally do, or 
make a sharp turn, and fully retract when you 
release the seat belt buckle.

■

Automatic Seat Belt Tensioners

1

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.

■

Seat Belt e-pretensioners

3.

Position the lap part of the belt as low as 
possible across your hips, then pull up on 
the shoulder part of the belt so the lap part 
fits snugly. This lets your strong pelvic 
bones take the force of a crash and reduces 
the chance of internal injuries.

4.

If necessary, pull up on the belt again to 
remove any slack, then check that the belt 
rests across the center of your chest and 
over your shoulder. This spreads the forces 
of a crash over the strongest bones in your 
upper body.

The front seats have adjustable shoulder anchors to accommodate taller and shorter 
occupants.

1.

Move the anchor up and down while 
holding the release button.

2.

Position the anchor so that the belt rests 
across the center of your chest and over 
your shoulder.

Advice for Pregnant Women

Each time you have a checkup, ask your doctor if it is 
okay for you to drive.

To reduce the risk of injuries to both you and your 
unborn child that can be caused by an inflating front 
airbag:

•

When driving, sit upright and adjust the seat as far 
back as possible while allowing full control of the 
vehicle.

•

When sitting in the front passenger’s seat, adjust 
the seat as far back as possible.

Wear the shoulder belt 
across the chest avoiding 
the abdomen.

Wear the lap part of the 
belt as low as possible 
across the hips.

Seat Belt Inspection

Safe Driving

Seat Belt Inspection

Regularly check the condition of your seat belts as follows:

•

Pull each belt out fully, and look for frays, cuts, burns, and wear.

•

Check that the latch plates and buckles work smoothly and the belts retract 
easily.

u

If a belt does not retract easily, cleaning the belt may correct the problem. Only 
use a mild soap and warm water. Do not use bleach or cleaning solvents. Make 
sure the belt is completely dry before allowing it to retract.

Any belt that is not in good condition or working properly will not provide proper 
protection and should be replaced as soon as possible.
A belt that has been worn during a crash may not provide the same level of 
protection in a subsequent crash. Have your seat belts inspected by a dealer after 
any collision.

WARNING

Not checking or maintaining seat belts can 
result in serious injury or death if the seat 
belts do not work properly when needed.

Check your seat belts regularly and have 
any problem corrected as soon as possible.
