Safety Warnings and Symbols
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
with a slash through it in
this book. This safety
symbol means “Do Not,”
“Do Not do this” or
“Do Not let this happen.”
iii

Vehicle Damage Warnings
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.
Vehicle Symbols
The vehicle has components and labels that use
symbols instead of text. Symbols are shown along
with the text describing the operation or information
relating to a specific component, control, message,
gage, or indicator.
If you need help figuring out a specific name of a
component, gage, or indicator, reference the
following topics:
•Seats and Restraint Systems in Section 1
•Features and Controls in Section 2
•Instrument Panel Overview in Section 3
•Climate Controls in Section 3
•Warning Lights, Gages, and Indicators in Section 3
•Audio System(s) in Section 3
•Engine Compartment Overview in Section 5

Front Seats
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. Lift the 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 be sure the seat is locked in place.
1-3

Power Seats If you have this feature, the power seat controls are
located on the outboard side of the front seat cushions.
The horizontal control adjusts the seat cushion and
the vertical control adjusts the seatback.
•Move the front of the seat control up or down to
adjust the front portion of the cushion.
•Move the rear of the seat control up or down to
adjust the rear portion of the cushion.
•Lift up or push down on the center of the seat
control to move the entire seat up or down.
•To move the seat forward or rearward, slide the
seat control forward or rearward.
•To recline the seatback, press the vertical control
rearward. To raise the seatback, press the vertical
control forward. See Reclining Seatbacks on
page 1-7 for more information.
1-4

Manual Lumbar
If your vehicle has this
feature, there is a knob
located on the outboard
side of the driver’s seat.
Turn the knob counterclockwise to increase lumbar
support and clockwise to decrease lumbar support.
Power Lumbar
Your vehicle may have this feature.
The control is located
on the outboard side
of the seat cushion.
To increase or decrease support, hold the control
forward or rearward. Keep in mind that as your
seating position changes, as it may during long trips,
so should the position of your lumbar support.
Adjust the seat as needed.
1-5

Heated Seats
Your vehicle may have
heated front seats. The
buttons used to control this
feature are located on
the front door armrests.
The engine must be
running for the heated
seat feature to work.
To heat the entire seat, press the horizontal button with
the heated seat symbol. Press the button repeatedly
to cycle through the temperature settings of high,
medium, low and off. The indicator lights above the
button will glow to designate the level of heat selected:
three for high, two for medium, and one for low.
The low setting warms the seatback and seat 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.
To heat only the seatback, press the button with the
words BACK ONLY. An indicator light on the switch
will glow to designate that only the seatback is being
heated. Additional presses will cycle through the
heat levels for the seatback only. Press the horizontal
button again to heat the whole seat.
The feature will shut off automatically when the ignition
is turned off.
1-6

Reclining Seatbacks
If your vehicle has a manual recliner, lift the lever
located on the outboard side of the seat and push the
seatback rearward to recline the seatback. To return
the seatback to the normal position, lift the lever without
pushing rearward on the seatback and the seatback
will move forward.
If your vehicle has
power seats, the power
reclining seatback
control is located on
the outboard side of
the front seat cushions.
Press the control rearward
to recline the seatback.
Press the control forward
to raise the seatback.
1-7

But do not have a seatback reclined if your vehicle is
moving.
{CAUTION:
Sitting in a reclined position when your vehicle
is in motion can be dangerous. Even if you
buckle up, your safety belts cannot do their
job when you are reclined like this.
The shoulder belt cannot do its job. In a crash,
you could go into it, receiving neck or other
injuries.
The lap belt cannot 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.
1-8

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.
The head restraints lock into place when raised.
To release the head restraint and lower it, press the
tab located on the top of the seatback.
Rear Seats

Envoy/Envoy Denali
Your vehicle may have a folding rear seat which lets
you fold the seatbacks down for more cargo space.

meets the seatback to fold the seat cushion up and
out of the way. This will allow the seatback to fold flat
and increase the cargo area.
1-9

The rear seatback
levers are located on
the outboard side of
the rear seatbacks.
Pull the seatback toward you as you lift up on the lever.
The head restraint will automatically fold out of the
way when the seatback is folded down.
To raise the seatbacks, lift up the seatbacks and
push on them until they lock into the upright position.
Push and pull on the seatbacks to make sure that
they are latched securely. Then fold the bottom seat
cushion back into place.
To return the head restraint to the upright position,
reach behind the seat and pull the restraint up until it
locks into place. Push and pull on the head restraint to
make sure that it is latched securely.

Safety Belts
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.
1-12

{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 3-34.
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.
A few crashes are mild, and some crashes can be so
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!
1-13

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.
