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.

Important Handling Information

Safe Driving

Important Handling Information

Your vehicle has higher ground clearance than a passenger vehicle designed for use
only on pavement. Higher ground clearance has many advantages for off-highway
driving. It allows you to travel over bumps, obstacles, and rough terrain. It also
provides good visibility so you can anticipate problems earlier.

These advantages come at some cost. Because your vehicle is taller and rides higher
off the ground, it has a higher center gravity making it more susceptible to tipping
or roll over if you make abrupt turns. Utility vehicles have a significantly higher
rollover rate than other types of vehicles. In a rollover crash, an unbelted person is
significantly more likely to die than a person wearing a seat belt. As a reminder,
make sure you and your passengers always wear seat belts.

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

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 and the tailgate are
closed and locked. Locking the doors and the tailgate helps prevent an occupant
from being ejected and an outsider from unexpectedly opening a door or the
tailgate.

2

Locking/Unlocking the Doors from the Inside

P. 163

•

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. 210

•

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. 216

•

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

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.

Installing a Child Seat with a Lap/Shoulder Seat Belt

P. 69

1

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.

■

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.

About Your Seat Belts

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 knee airbags.

■

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.

1.

Pull the seat belt out slowly.

2.

Insert the latch plate into the buckle, then
tug on the belt to make sure the buckle is
secure.

Make sure that the belt is not twisted or
caught on anything.

1

Fastening a Seat Belt

No one should sit in a seat with an inoperative seat
belt or one that does not appear to be working
correctly. Using a seat belt that is not working
properly may not protect the occupant in a crash.
Have a dealer check the belt as soon as possible.

Never insert any foreign objects into the buckle or
retractor mechanism.

If the seat belt appears to be locked in a fully
retracted position, firmly pull out on the shoulder belt
once, then push it back in.
Then smoothly pull it out of the retractor and fasten.
If you are unable to release the seat belt from a fully
retracted position, do not allow anyone to sit in the
seat, and take your vehicle to a dealer for repair.

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

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.
