Seats and Restraints 2-7
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.
On vehicles with heated front seats,
the controls are located near the
climate controls. To operate the
heated seats the ignition must be
in ON/RUN.
Press the buttonLto heat the seat
cushion and seatback.
Press the button once for the
highest setting. With each press, the
heated seat will change to the next
lower setting, and then the off
setting. The lights indicate three for
the highest setting and one for the
lowest. The passenger seat may take
longer to heat up.
When Remote Keyless Entry (RKE)
transmitter is used to remote start
the vehicle, the front heated seats
will heat to the highest setting if it is
cold outside. When the ignition is
turned on with the key the heated
seat feature turns off. Press the
button to turn the feature back on.

Seats and Restraints 2-43
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.
{WARNING
Children can be seriously injured
or strangled if a shoulder belt is
wrapped around their neck and
the safety belt continues to
tighten. Never leave children
unattended in a vehicle and never
allow children to play with the
safety belts.Airbags plus lap‐shoulder belts offer
protection for adults and older
children, but not for young children
and infants. Neither the vehicle's
safety belt system nor its airbag
system is designed for them. Every
time infants and young children ride
in vehicles, they should have the
protection provided by appropriate
child restraints.
Children who are not restrained
properly can strike other people,
or can be thrown out of the vehicle.
