Safety Warnings and Symbols
Information Provided by:
There are a number of safety cautions in this book. We
use a box and the word CAUTION to tell about things
that could hurt you if you were to ignore the warning.
{CAUTION:
These mean there is something that could hurt
you or other people.
In the caution area, we tell you what the hazard is.
Then we tell you what to do to help avoid or reduce the
hazard. Please read these cautions. If you do not,
you or others could be hurt.
You will also find a circle

Also, in this manual you will find these notices:
Notice: These mean there is something that could
damage your vehicle.
A notice tells about something that can damage the
vehicle. Many times, this damage would not be covered
by your vehicle’s warranty, and it could be costly. But
the notice will tell what to do to help avoid the damage.
When you read other manuals, you might see
CAUTION and NOTICE warnings in different colors or in
different words.
There are also warning labels on the vehicle. They use
the same words, CAUTION or NOTICE.

Front Seats
Information Provided by:
Manual Seats
{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 do not want to. Adjust the driver’s
seat only when the vehicle is not moving.
If your vehicle has a manual bucket or a split bench
seat, you can adjust it with this lever located at the front
of the seat.
Lift the lever 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 to make sure the
seat is locked into place.

Power Seats
Information Provided by:
If your vehicle has a power seat, you can adjust
it with these controls located on the outboard sides
of the seats.
• Raise or lower the front of the seat cushion by
raising or lowering the forward edge of the
horizontal control.
• Move the seat forward or rearward by moving the
whole horizontal control forward or rearward.
• Raise or lower the rear of the seat cushion by
raising or lowering the rear edge of the horizontal
control.
• Moving the whole horizontal control up or down
raises or lowers the entire seat cushion.
If your vehicle has power reclining seats, you can use
the vertical control to adjust the angle of the seatback.
Move the reclining front seatback rearward or forward
by moving the control toward the rear or the front of the
vehicle. See Reclining Seatbacks on page 1-6.
1-4
Power Lumbar
Information Provided by:
Your vehicle’s seats may be equipped with power
lumbar.
You can increase or
decrease lumbar support
in an area of the lower
seatback with this control,
located on the outboard
sides of the front seat(s).
To increase support, press and hold the front of the
control. To decrease support, press and hold the rear of
the control. Let go of the control when the lower
seatback reaches the desired level of support.
You can also reshape the side wing area of the lower
seatback for more lateral support.
To increase support, press and hold the top of the
control. To decrease support, press and hold the bottom
of the control. Let go of the control when the lower
seatback reaches the desired level of support.
Your vehicle may have a memory function which allows
seat settings to be saved and recalled. See Memory
Seat on page 2-74 for more information.
Heated Seats
If your vehicle is equipped
with this feature, the
buttons are located on the
front doors. The engine
must be running for
the heated seats to work.
To heat the entire seat, press the horizontal button with
the heated seat and seatback symbol. Press the button to
cycle through the temperature settings of high, medium
and low and to turn the heated seat off. Indicator lights
will be lit to designate the level of heat selected: three for
high, two for medium, and one for low.
The low setting warms the seatback and cushion until
the seat temperature is near body temperature. The
medium and high settings heat the seatback and seat
cushion to a slightly higher temperature. You will be able
to feel heat in about two minutes.
1-5
To heat only the seatback, press the vertical button with
Information Provided by:
the heated seatback symbol. An indicator light on the
seatback button will be lit to designate that only the
seatback is being heated. Additional presses of
the seatback button will cycle through the heat levels for
the seatback only. Press the horizontal button again
to heat the whole seat.
The heated front seats will shut off automatically when
the ignition is turned off.
Reclining Seatbacks
To adjust the front seatback, lift the manual lever
located on the outboard side of the seat. Release the
lever to lock the seatback where you want it. Lift
the lever again without pushing on the seatback and the
seatback will go to an upright position.
If your vehicle has power seats with a power recliner,
see Power Seats on page 1-4 for further information on
how to operate the reclining seatback feature.
1-6
But don’t have a seatback reclined if your vehicle is
Information Provided by:
moving.
{CAUTION:
Sitting in a reclined position when your vehicle
is in motion can be dangerous. Even if you
buckle up, your safety belts can not do their
job when you are reclined like this.
The shoulder belt can not do its job. In a
crash, you could go into it, receiving neck or
other injuries.
The lap belt can not do its job either. In a
crash the belt could go up over your abdomen.
The belt forces would be there, not at your
pelvic bones. This could cause serious internal
injuries.
For proper protection when the vehicle is in
motion, have the seatback upright. Then sit
well back in the seat and wear your safety belt
properly.
1-7
Head Restraints
Information Provided by:
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.
To raise the head restraint pull up on the head restraint.
Your vehicle may have rear seat head restraints that
can be adjusted up and down.
Seatback Latches
{CAUTION:
If the seatback is not 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.
The seatbacks fold forward to let you access the rear of
the cab.
To fold a front seatback forward, lift the lever at the
base of the seat to release the seatback.
The lever is located on the outboard side of the seat
cushion.
To return the seatback to the upright position, push the
seatback rearward until it latches. After returning the
seatback to its upright position, push and pull on
the seatback to make sure it is locked.
1-8

Folding the Rear Seat
The extended cab’s rear seat can be folded up to
provide more cargo space. To fold the seat do the
following:
1. Push down on the seat
while pulling forward on
the release strap
located under the rear
seat cushion.
2. Pull the seat cushion up until it latches with the
seatback.
3. After latching the seat cushion up, gently pull
forward on it to make sure it is locked.
The extended cab’s rear seat can also be folded open
for more seating space. To use the seat do the following:
1. Push rearward on the seat cushion while pulling
forward on the release strap under the seat
cushion. Pull the seat cushion down until it latches.
2. After latching the seat cushion down, gently pull up
on it to make sure it is locked.
1-9
Rear Seat Operation (Crew Cab)
Information Provided by:
The second row rear seat has a 60/40 split seat. Either
side of the rear seat may be folded down to give
you more cargo space.
Make sure that nothing is under or in front of the seat
and that the head restraints are completely lowered.
To fold the rear seat, do the following:
1. Pull up on the strap
loop at the rear of the
seat cushion. Then,
pull the seat cushion up
and fold it forward.
2. After folding the seat cushion fully forward, pull the
seatback forward and fold the seatback down until it
is flat. If the seatback cannot fold flat because it
interferes with the cushion, try moving the front seat
forward and/or bringing the front seat more
upright. The lever at the base of the seat must be
turned rearward to release the seatback.
To return the seat to the passenger position do the
following:
1. Lift the seatback up and push it rearward all
the way.
2. Lower the seat cushion until it latches into position.
3. Pull forward on the seatback and up on the seat
cushion to make sure the seat is securely in
place.
Check to see that the buckles on the driver’s side
seatback are accessible to the outboard and center
occupant and are not under the seat cushions.

Safety Belts
Information Provided by:
Safety Belts: They Are for Everyone
This part of the manual tells you how to use safety
belts properly. It also tells you some things you should
not do with safety belts.
{CAUTION:
Do not let anyone ride where he or she can not
wear a safety belt properly. If you are in a
crash and you are not wearing a safety belt,
your injuries can be much worse. You can hit
things inside the vehicle or be ejected from it.
You can be seriously injured or killed. In the
same crash, you might not be, if you are
buckled up. Always fasten your safety belt,
and check that your passengers’ belts are
fastened properly too.
{CAUTION:
It is extremely dangerous to ride in a cargo
area, inside or outside of a vehicle. In a
collision, people riding in these areas are more
likely to be seriously injured or killed. Do not
allow people to ride in any area of your vehicle
that is not equipped with seats and safety
belts. Be sure everyone in your vehicle is in a
seat and using a safety belt properly.
Your vehicle has a light
that comes on as a
reminder to buckle up. See
Safety Belt Reminder
Light on page 3-33.
In most states and in all Canadian provinces, the law
says to wear safety belts. Here is why: They work.
You never know if you will be in a crash. If you do have
a crash, you do not know if it will be a bad one.
1-11
A few crashes are mild, and some crashes can be so
Information Provided by:
serious that even buckled up, a person would not
survive. But most crashes are in between. In many of
them, people who buckle up can survive and sometimes
walk away. Without belts they could have been badly
hurt or killed.
After more than 30 years of safety belts in vehicles, the
facts are clear. In most crashes buckling up does
matter...a lot!
Why Safety Belts Work
When you ride in or on anything, you go as fast as
it goes.
Take the simplest vehicle. Suppose it is just a seat on
wheels.

Put someone on it. Get it up to speed. Then stop the vehicle. The rider

Questions and Answers About
Information Provided by:
Safety Belts
Q: Will I be trapped in the vehicle after an accident
if I am wearing a safety belt?
A: You could be — whether you are wearing a safety
belt or not. But you can unbuckle a safety belt,
even if you are upside down. And your chance of
being conscious during and after an accident,
so you can unbuckle and get out, is much greater if
you are belted.
Q: If my vehicle has airbags, why should I have to
wear safety belts?
or the safety belts!
With safety belts, you slow down as the vehicle does.
You get more time to stop. You stop over more distance,
and your strongest bones take the forces. That is why
safety belts make such good sense.
A: Airbags are in many vehicles today and will be in
most of them in the future. But they are
supplemental systems only; so they work with
safety belts — not instead of them. Every airbag
system ever offered for sale has required the use of
safety belts. Even if you are in a vehicle that has
airbags, you still have to buckle up to get the most
protection. That is true not only in frontal collisions,
but especially in side and other collisions.
1-15
Q: If I am a good driver, and I never drive far from
Information Provided by:
home, why should I wear safety belts?
A: You may be an excellent driver, but if you are in an
accident — even one that is not your fault — you
and your passengers can be hurt. Being a good
driver does not 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
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 1-33
or Infants and Young Children on page 1-35. Follow
those rules for everyone’s protection.
First, you will want to know which restraint systems your
vehicle has.
We will start with the driver position.
Driver Position
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.
1-16
3. Pick up the latch plate and pull the belt across you.
Information Provided by:
Do not let it get twisted.
The 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 is not long enough, see Safety Belt
Extender on page 1-32.
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.
5. To make the lap part tight, pull down on the buckle
end of the belt as you pull up on the shoulder belt.
1-17
The lap part of the belt should be worn low and snug on
Information Provided by:
the hips, just touching the thighs. In a crash, this
applies force to the strong pelvic bones. And you would
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 is a sudden stop or crash,
or if you pull the belt very quickly out of the retractor.
1-18
Q: What is wrong with this?
Information Provided by:
A: The shoulder belt is too loose. It will not give nearly
as much protection this way.
{CAUTION:
You can be seriously hurt if your shoulder belt
is too loose. In a crash, you would move
forward too much, which could increase injury.
The shoulder belt should fit against your body.
1-19
Q: What is wrong with this?
Information Provided by:
A: The belt is buckled in the wrong place.
{CAUTION:
You can be seriously injured if your belt is
buckled in the wrong place like this. In a crash,
the belt would go up over your abdomen. The
belt forces would be there, not at the pelvic
bones. This could cause serious internal
injuries. Always buckle your belt into the
buckle nearest you.
1-20
Q: What is wrong with this?
Information Provided by:
A: The belt is over an armrest.
{CAUTION:
You can be seriously injured if your belt goes
over an armrest like this. The belt would be
much too high. In a crash, you can slide under
the belt. The belt force would then be applied
at the abdomen, not at the pelvic bones, and
that could cause serious or fatal injuries. Be
sure the belt goes under the armrests.
1-21
Q: What is wrong with this?
Information Provided by:
A: The shoulder belt is worn under the arm. It should
be worn over the shoulder at all times.
{CAUTION:
You can be seriously injured if you wear the
shoulder belt under your arm. In a crash, your
body would move too far forward, which would
increase the chance of head and neck injury.
Also, the belt would apply too much force to
the ribs, which are not as strong as shoulder
bones. You could also severely injure internal
organs like your liver or spleen.
1-22
Q: What is wrong with this?
Information Provided by:
A: The belt is twisted across the body.
{CAUTION:
You can be seriously injured by a twisted belt.
In a crash, you would not have the full width of
the belt to spread impact forces. If a belt is
twisted, make it straight so it can work
properly, or ask your dealer to fix it.
1-23
To unlatch the belt, just push the button on the buckle.
Information Provided by:
The belt should go back out of the way.
Before you close the door, be sure the belt is out of the
way. If you slam the door on it, you can damage
both the belt and your vehicle.
