Vehicle Damage Warnings
Also, in this book you will nd these notices:
Notice:These mean there is something that could
damage your vehicle.
A notice will tell you about something that can damage
your vehicle. Many times, this damage would not be
covered by your warranty, and it could be costly. But the
notice will tell you 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.
You’ll also see warning labels on your vehicle. They use
the same words, CAUTION or NOTICE.
Vehicle Symbols
Your vehicle has components and labels that use
symbols instead of text. Symbols, used on your vehicle,
are shown along with the text describing the operation
or information relating to a specic component, control,
message, gage or indicator.
If you need help guring out a specic name of a
component, gage or indicator, reference the following

Heated Seats
Your vehicle may have
heated front seats. The
buttons used to control this
feature are located on the
front doors. 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 to cycle
through the temperature settings of high, medium and
low and to turn the heated seat off. Indicator lights
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 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 vertical button with
the heated seatback symbol. An indicator light on the
seatback button will glow 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
Your vehicle’s front seatbacks have a recline feature
which is described earlier. SeePower Seats on
page 1-2.
But don’t 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 can’t do their job
when you’re reclined like this.
The shoulder belt can’t do its job. In a crash,
you could go into it, receiving neck or other
injuries.
The lap belt can’t 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.
