How to Wear Safety Belts Properly
This part is only for people of adult size.
Be aware that there are special things to know about
safety belts and children. And there are different
rules for smaller children and babies. If a child will be
riding in your vehicle, seeOlder Children on page 1-22
orInfants and Young Children on page 1-25. Follow
those rules for everyone’s protection.
First, you’ll want to know which restraint systems your
vehicle has.
We’ll start with the driver position.
Driver Position
This part describes the driver’s restraint system.
Lap-Shoulder Belt
The driver has a lap-shoulder belt. Here is how to wear
it properly.
1. Close and lock the door.
2. Adjust the seat so you can sit up straight. To see
how, see “Seats” in the Index.3. Pick up the latch plate and pull the belt across you.
Do not let it get twisted.
The lap-shoulder belt may lock if you pull the belt
across you very quickly. If this happens, let the belt
go back slightly to unlock it. Then pull the belt
across you more slowly.

The best way to protect the fetus is to protect the
mother. When a safety belt is worn properly, it’s more
likely that the fetus won’t be hurt in a crash. For
pregnant women, as for anyone, the key to making
safety belts effective is wearing them properly.
Right Front Passenger Position
To learn how to wear the right front passenger’s safety
belt properly, seeDriver Position on page 1-11.
The right front passenger’s safety belt works the same
way as the driver’s safety belt — except for one
thing. If you ever pull the lap portion of the belt out all
the way, you will engage the child restraint locking
feature. If this happens, just let the belt go back all the
way and start again.
Rear Seat Passengers
It is very important for rear seat passengers to buckle
up! Accident statistics show that unbelted people in
the rear seat are hurt more often in crashes than those
who are wearing safety belts.
Rear passengers who are not safety belted can be
thrown out of the vehicle in a crash. And they can strike
others in the vehicle who are wearing safety belts.

3. Pick up the latch plate, and run the lap and shoulder
portions of the vehicle’s safety belt through or
around the restraint. The child restraint instructions
will show you how.
4. Buckle the belt. Make sure the release button is
positioned so you would be able to unbuckle the
safety belt quickly if you ever had to.5. Pull the rest of the lap belt all the way out of the
retractor to set the lock.

Doors and Locks
Door Locks
{CAUTION:
Unlocked doors can be dangerous.
•Passengers — especially children — can
easily open the doors and fall out of a
moving vehicle. When a door is locked, the
handle will not open it. You increase the
chance of being thrown out of the vehicle
in a crash if the doors are not locked. So,
wear safety belts properly and lock the
doors whenever you drive.
CAUTION: (Continued)
CAUTION: (Continued)
•
Young children who get into unlocked
vehicles may be unable to get out. A child
can be overcome by extreme heat and can
suffer permanent injuries or even death
from heat stroke. Always lock your vehicle
whenever you leave it.
•Outsiders can easily enter through an
unlocked door when you slow down or
stop your vehicle. Locking your doors can
help prevent this from happening.
There are several ways to lock and unlock your vehicle.
Because your vehicle has the theft-deterrent system,
you must unlock the doors with the key or remote
keyless entry transmitter to avoid setting off the alarm.
From the outside, use either the key or the remote
keyless entry transmitter.

Try to adjust your speed so you can “drive” through the
curve. Maintain a reasonable, steady speed. Wait to
accelerate until you are out of the curve, and then
accelerate gently into the straightaway.
To help you steer in the direction you want to go, during
certain sharp or sudden cornering maneuvers, gear
selection is controlled. This will maximize the available
drive wheel torque and minimize the transaxle
response time and shift activity. During this kind of
maneuver, the transaxle shifts automatically as vehicle
speed changes.
Steering in Emergencies
There are times when steering can be more effective
than braking. For example, you come over a hill and find
a truck stopped in your lane, or a car suddenly pulls
out from nowhere, or a child darts out from between
parked cars and stops right in front of you. You
can avoid these problems by braking — if you can stop
in time. But sometimes you can not; there is not
room. That is the time for evasive action — steering
around the problem.
Your vehicle can perform very well in emergencies like
these. First apply your brakes.
SeeBraking on page 4-6. It is better to remove as much
speed as you can from a possible collision. Then
steer around the problem, to the left or right depending
on the space available.An emergency like this requires close attention and a
quick decision. If you are holding the steering wheel at
the recommended 9 and 3 o’clock positions, you
can turn it a full 180 degrees very quickly without
removing either hand. But you have to act fast, steer
quickly, and just as quickly straighten the wheel
once you have avoided the object.
The fact that such emergency situations are always
possible is a good reason to practice defensive driving
at all times and wear safety belts properly.
