Manual Seats
You can lose control of the vehicle if you try to
adjust
a manual driver’s seat while the vehicle
is moving. The sudden movement could startle
and confuse you, or make you push a pedal when you don’t want to. Adjust the driver’s
seat only when the vehicle is not moving.
Pull up on the control bar located under the front of the
seat to unlock it. Slide the seat to where you want it
and release the bar.
Try to move the seat with your body
to make sure the seat is locked into place. If
your vehicle has this feature, the controls for
the
power seats are located on the outboard side of each
front seat.

Reclining Seatbacks
If your vehicle has a power
recliner, the vertical control
described previously in
this section reclines
the front seatbacks.
If your vehicle has the manual recliner, lift the lever on
the outboard side
of the seat and move the seatback
to the desired position. Release the lever to lock
the seatback. Pull up on the lever without pushing on
the seatback and the seatback will go to an upright
position. But don’t
have a seatback reclined
if your vehicle is
moving.

Q: If I’m a good driver, and I never drive far from
At You may be an excellent driver, but if you’re in an
accident
- even one that isn’t your fault - you and
your passengers can be hurt. Being a good
driver doesn’t protect you from things beyond your
control, such as bad drivers.
Most accidents occur within
25 miles (40 km) of
home. And the greatest number of serious injuries
and deaths occur at speeds of less than
40 mph (65 km/h).
Safety belts are for everyone.
home, why should I wear safety belts?
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, see
Older Children on page 7-27
or lnfants and Young Children on page 1-29. 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’s 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.
1-12
Page 20 of 418

3. Pick up the latch plate and pull the belt across you.
Don’t 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.
4. Push the latch plate into the buckle until it clicks.
Pull up on the latch plate
to make sure it is
secure.
If the belt isn’t long enough, see Safety
Belt Extender on page 1-26.
Make sure the release button on the buckle is
positioned
so you would be able to unbuckle the
safety belt quickly
if you ever had to.
The lap part of the belt should be worn low and
snug on
the hips, just touching the thighs. In a crash, this
applies force to the strong pelvic bones. And you’d be
the belt would apply force at your abdomen. This
could cause serious or even fatal injuries. The shoulder
belt should go over the shoulder and across the
chest. These parts of the body are best able
to take belt
restratnmgforces.---
~~~~~ ~~~ ~ ~ ~~ ~~.
The safety belt locks if there’s a sudden stop or crash,
or
if you pull the belt very quickly out of the retractor.

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, see
Driver Position on page 1-72.
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.
If your vehicle has a center passenger position, be sure
to use the correct buckle when buckling your lap
shoulder belt.
If you find that the latch plate will not go
fully into the buckle, see
if you are using the buckle
for the center passenger position.

Rear Seat Passengers
It’s 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 aren’t 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.
Lap-Shoulder Belt
All rear seating positions have lap-shoulder belts. Here’s
how to wear one properly.
U
1. Pick up the latch plate and pull the belt across you.
Don’t let
it get twisted.
The shoulder belt may lock
if you pull the belt
across you
very quickiy. if this happens, let the belt
go back slightly to unlock it. Then pull the belt
across you more slowly.
