2010 HUMMER H3 Owners Manual

Seats and Restraints 3-5
The seats have manual reclining
seatbacks. The lever used to
operate them is located on the
outboard side of the seats.
To recline the seatback:
1. Lift the recline lever and movethe seatback to the desired
position, then release the lever
to lock the seatback in place.
2. Push and pull on the seatback to make sure it is locked. To return the seatback to an upright
position:
1. Lift the lever fully without
applying pressure to the
seatback.
2. Push and pull on the seatback to make sure it is locked.
Do not have a seatback reclined
when the vehicle is moving.
{WARNING
Sitting in a reclined position when
the vehicle is in motion can be
dangerous. Even when buckled
up, the safety belts cannot do
their job when reclined like this.
The shoulder belt cannot do its
job because it will not be against
your body. Instead, it will be in
front of you. 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 the
safety belt properly.

3-6 Seats and Restraints
Heated Front Seats
{WARNING
If you cannot feel temperature
change or pain to the skin, the
seat heater may cause burns
even at low temperatures.
To reduce the risk of burns,
people with such a condition
should use care when using
the seat heater, especially for
long periods of time. Do not
place anything on the seat that
insulates against heat, such as
a blanket, cushion, cover or
similar item. This may cause
the seat heater to overheat.
An overheated seat heater may
cause a burn or may damage
the seat.This feature heats the cushion and
seatbacks.

controls are located on the outboard
sides of the front seats.

turn the heat to the high setting.

ignition has been turned off and
then turned back on.

on the passenger seat the safety
belt must be fastened.

Safety Belts
This section of the manual
describes how to use safety belts
properly. It also describes some
things not to do with safety belts.
{WARNING
Do not let anyone ride where
a safety belt cannot be worn
properly. In a crash, if you or your
passenger(s) are not wearing
safety belts, the injuries can be
much worse. You can hit things
inside the vehicle harder or
be ejected from the vehicle.
You and your passenger(s) 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 passenger(s)
are restrained properly too.

Seats and Restraints 3-11
{WARNING
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.
{WARNING
People riding on the tailgate
(if equipped) can easily lose their
balance and fall even when the
vehicle is operated at low speeds.
Falling from a moving vehicle may
result in serious injuries or death.
This vehicle has indicators as a
reminder to buckle the safety belts.
See Safety Belt Reminders
on
page 5‑9for additional information. In most states and in all Canadian
provinces, the law requires wearing
safety belts. Here is why:
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
serious 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
safety belts they could have been
badly hurt or killed.
After more than 40 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 does not stop.
