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.
On vehicles with this feature the
controls are located on the outboard
sides of the front seats.
Press the top of the switch to
turn the heat to the high setting.
Press the bottom of the switch to
turn the heat to the low setting.
Put the switch in the center position
to turn the heat off.
The ignition must be on for the
heated seat feature to work. The
seat will heat to the last setting if the
ignition has been turned off and
then turned back on.
For the heated seat feature to work
on the passenger seat the safety
belt must be fastened.

3-44 Seats and Restraints
{WARNING
Never do this.
Never allow two children to wear
the same safety belt. The safety
belt can not properly spread the
impact forces. In a crash, the
two children can be crushed
together and seriously injured.
A safety belt must be used by
only one person at a time.
{WARNING
Never do this.
Never allow a child to wear the
safety belt with the shoulder belt
behind their back. A child can be
seriously injured by not wearing
the lap-shoulder belt properly.
In a crash, the child would not be
restrained by the shoulder belt.
The child could move too far
forward increasing the chance of
head and neck injury. The child
might also slide under the lap
belt. The belt force would then be
applied right on the abdomen.
That could cause serious or fatal
injuries. The shoulder belt should
go over the shoulder and across
the chest.
Infants and Young
Children
Everyone in a vehicle needs
protection! This includes infants
and all other children. Neither the
distance traveled nor the age and
size of the traveler changes the
need, for everyone, to use safety
restraints. In fact, the law in every
state in the United States and in
every Canadian province says
children up to some age must be
restrained while in a vehicle.
