Rear Heated Seats — If Equipped
On some models, the two rear outboard seats may be
equipped with heated seats. There are two heated seat
switches that allow the rear passengers to operate the seats
independently. The heated seat switches for each heater are
located on the rear of the center console.
You can choose from HI, LO, or OFF heat settings. Amber
indicator lights in each switch indicate the level of heat in
use. Two indicator lights will illuminate for HI, one for LO
and none for OFF.Push the switch once to select HI-level heating. Push the
switch a second time to select LO-level heating. Push the
switch a third time to shut the heating elements off.
When the HI-level setting is selected, the heater will
provide a boosted heat level during the first four minutes
of operation. Then, the heat output will drop to the normal
HI-level. If the HI-level setting is selected, the system will
automatically switch to LO-level after approximately 60
minutes of continuous operation. At that time, the number
of indicator lights changes from two to one, indicating the
change. The LO-level setting will turn off automatically
after approximately 45 minutes.

WARNING!(Continued)
•ALWAYS make sure objects cannot fall or slide into
the driver ’s side floor area when the vehicle is
moving. Objects can become trapped under accelera-
tor, brake, or clutch pedals and could cause a loss of
vehicle control.
• NEVER place any objects under the floor mat (e.g.,
towels, keys, etc.). These objects could change the
position of the floor mat and may cause interference
with the accelerator, brake, or clutch pedals.
• If the vehicle carpet has been removed and re-
installed, always properly attach carpet to the floor
and check the floor mat fasteners are secure to the
vehicle carpet. Fully depress each pedal to check for
interference with the accelerator, brake, or clutch
pedals then re-install the floor mats.
• It is recommended to only use mild soap and water
to clean your floor mats. After cleaning, always check
your floor mat has been properly installed and is
secured to your vehicle using the floor mat fasteners
by lightly pulling mat.
Periodic Safety Checks You Should Make Outside
The Vehicle
Tires
Examine tires for excessive tread wear and uneven wear
patterns. Check for stones, nails, glass, or other objects
lodged in the tread or sidewall. Inspect the tread for cuts
and cracks. Inspect sidewalls for cuts, cracks, and bulges.
Check the wheel nuts for tightness. Check the tires (includ-
ing spare) for proper cold inflation pressure.
Lights
Have someone observe the operation of brake lights and
exterior lights while you work the controls. Check turn
signal and high beam indicator lights on the instrument
panel.

SAFETY 247

The system requires that the engine be running for all
changes. When lowering the vehicle all of the doors,
including the liftgate, must be closed. If a door is opened at
any time while the vehicle is lowering the change will not
be completed until the open door(s) is/are closed.
The Quadra-Lift air suspension system uses a lifting and
lowering pattern which keeps the headlights from incor-
rectly shining into oncoming traffic. When raising the
vehicle, the rear of the vehicle will move up first and then
the front. When lowering the vehicle, the front will move
down first and then the rear.
After the engine is turned off, it may be noticed that the air
suspension system operates briefly, this is normal. The
system is correcting the position of the vehicle to ensure a
proper appearance.
To assist with changing a spare tire, the Quadra-Lift air
suspension system has a feature which allows the auto-
matic leveling to be disabled. Refer to “Uconnect Settings”
in “Multimedia” for further information.
For further information refer to “Driving Tips” in “Starting
And Operating” section.NOTE:
If equipped with a touch screen radio all enabling/
disabling of air suspension features must be done through
the radio. Refer to “Uconnect Settings” in “Multimedia” for
further information.
