Vehicle Damage Warnings
Also, in this book you will find 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 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

Power Lumbar
Heated Seats
You can increase or
decrease lumbar support in an area of the lower
seatback.
To increase support, press and hold the front of the
control.
To decrease support, press and hold the rear of
the control. Let go of the control when the lower
seatback reaches the desired level of support.
You can also reshape the side wing area
of the lower
seatback for more lateral support.
To increase support, press and hold the top of the
control. To decrease support, press and hold the bottom
of the control. Let go of the control when the lower
seatback reaches the desired level
of support.
-1 control this feature are
The
buttons used
to
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.
Your vehicle also has rear heated seats. See Heated
Seats
on page 1-8.
Reclining Seatbacks
The vertical power seat control described earlier allows
the seatback
to recline.
But don’t have a seatback reclined
if your vehicle is
moving. Sitting
in a
re nec losition when your ve :le
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.
