Seats and Seat Controls
This section tells you about the seats -- how to adjust
them, and fold them up and down. It also tells you about
reclining front seatbacks and head restraints.
Manual Front Seat
CAUTION:
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.
You can adjust the seat
with this lever located at
the front of the seat.
Slide the lever toward the passenger's side to unlock the
seat. Using your body, slide the seat to where you want
it and release the lever. Try to move the seat with your
body in order to make sure the seat is locked into place.

1-3 Power Lumbar Control (If Equipped)
If your vehicle has the
power lumbar feature, you
can increase or decrease
lumbar support in an area
of the lower seatback.
The switch is located on
the outboard side of the
driver's seat cushion.
To increase support, press and hold the front of the
rocker switch. Let go of the switch when the lower
seatback reaches the desired level of support.
To decrease support, press and hold the rear of the
rocker switch. Let go of the switch when the lower
seatback reaches the desired level of support.
Reclining Seatbacks
The reclining seatback lever is located on the outboard
sides of the driver's and passenger's seats. To adjust the
front seatback, move the lever rearward. Release the
lever to lock the seatback where you want it. Move the
lever rearward without pushing on the seatback.
The seatback will go to an upright position.

1-5 Head Restraints
Adjust your head restraint so that the top of the restraint
is closest to the top of your head. This position reduces
the chance of a neck injury in a crash.
Seatback Latches
The front seatback folds forward to let you access the
rear of the cab. To fold the seatback, pull the easy entry
lever located on the side of the seat. To return the
seatback to the upright position, push the seatback
rearward until it latches. Then it will lock into place.
CAUTION:
If the seatback isn't locked, it could move forward
in a sudden stop or crash. That could cause injury
to the person sitting there. Always press rearward
on the seatback to be sure it is locked.

Q:If I'm a good driver, and I never drive far from
home, why should I wear safety belts?
A: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.
How to Wear Safety Belts Properly
Adults
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 the part of this manual called
ªChildren.º 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 ªSeatsº in the Index.

1-12
3. Pick up the latch plate and pull the belt across you.
Don't let it get twisted.
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 ªSafety Belt
Extenderº at the end of this section.
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 less likely
to slide under the lap belt. If you slid under it, 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 restraining forces.
The safety belt locks if there's a sudden stop or a crash.

1-13
Shoulder Belt Height Adjuster
Before you begin to drive, move the shoulder belt
adjuster to the height that is right for you.To move it down, push in at the word PRESS and move
the height adjuster to the desired position. You can move
the adjuster up just by pushing up on the shoulder belt
guide. After you move the adjuster to where you want it,
try to move it down without pushing in to make sure it
has locked into position.
Adjust the height so that the shoulder portion of the
belt is centered on your shoulder. The belt should be
away from your face and neck, but not falling off
your shoulder.

1-20
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 ªDriver Positionº earlier in this section.
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.
Center Passenger Position
Lap Belt
When you sit in the center seating position, you have a
lap safety belt, which has no retractor. To make the belt
longer, tilt the latch plate and pull it along the belt.

1-32
4. Pull the rest of the lap belt all the way out of the
retractor to set the lock.5. To tighten the belt, feed the lap belt back into the
retractor while you push down on the child restraint.
If you're using a forward
-facing child restraint,
you may find it helpful to use your knee to push
down on the child restraint as you tighten the belt.
6. Push and pull the child restraint in different
directions to be sure it is secure.
To remove the child restraint, just unbuckle the vehicle's
safety belt and let it go back all the way. The safety belt
will move freely again and be ready to work for an adult
or larger child passenger.
