WARNING!(Continued)
•Do not place anything on the seat or seatback that
insulates against heat, such as a blanket or cushion.
This may cause the seat heater to overheat. Sitting
in a seat that has been overheated could cause
serious burns due to the increased surface tempera-
ture of the seat.
Front Heated Seats
The front heated seats control buttons are located on the
center instrument panel below the climate controls.
If your vehicle is equipped with a touchscreen, the front
heated seats control buttons are also located within the
climate or controls screen of the touchscreen.
• Press the heated seat button
once to turn the HI
setting On.
• Press the heated seat buttona second time to turn
the LO setting On.
• Press the heated seat buttona third time to turn
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 ap-
proximately 60 minutes of continuous operation. At that
time, the display will change from HI to LO, indicating
the change. The LO-level setting will turn OFF automati-
cally after approximately 45 minutes.
NOTE: The engine must be running for the heated seats
to operate.

to one, indicating the change. The LO-level setting will
turn OFF automatically after approximately 45 minutes.
Ventilated Seats — If Equipped
Located in the seat cushion are small fans that draw the
air from the passenger compartment and move air
through fine perforations in the seat cover to help keep
the driver and front passenger cooler in higher ambient
temperatures. The fans operate at two speeds, HI and LO. The front ventilated seats control buttons are located on
the center instrument panel below the climate controls.
If your vehicle is equipped with a touchscreen, the front
ventilated seats control buttons are also located within
the climate or controls screen of the touchscreen.

WARNING!
•Persons who are unable to feel pain to the skin
because of advanced age, chronic illness, diabetes,
spinal cord injury, medication, alcohol use, exhaus-
tion, or other physical conditions must exercise
care when using the steering wheel heater. It may
cause burns even at low temperatures, especially if
used for long periods.
• Do not place anything on the steering wheel that
insulates against heat, such as a blanket or steering
wheel covers of any type and material. This may
cause the steering wheel heater to overheat.
DRIVER ADJUSTABLE PEDALS — IF EQUIPPED
The adjustable pedals system is designed to allow a
greater range of driver comfort for steering wheel tilt and
seat position. This feature allows the brake, accelerator, and clutch pedals (if equipped) to move toward or away
from the driver to provide improved position with the
steering wheel.
The adjustable pedal switch is located to the left side of
the steering column.
•
The pedals can be adjusted with the ignition OFF.

4. Turn Signal IndicatorsThe arrow will flash with the exterior turn
signal when the turn signal lever is operated.
NOTE:
• A continuous chime will sound if the vehicle is
driven more than 1 mile (1.6 km) with either turn
signal on.
• Check for an inoperative outside light bulb if either
indicator remains on and does not flash, or flashes at
a rapid rate.
5. Voltmeter — If Equipped
When the engine is running, the gauge indicates
the electrical system voltage. The pointer should
stay within the normal range if the battery is charged. If
the pointer moves to either extreme left or right and
remains there during normal driving, the electrical sys-
tem should be serviced. NOTE:
The voltmeter may show a gauge fluctuation at
various engine temperatures. This cycling operation is
caused by the post-heat cycle of the intake manifold
heater system. The number of cycles and the length of the
cycling operation is controlled by the engine control
module. Post-heat operation can run for several minutes,
and then the electrical system and voltmeter needle will
stabilize.
6. Brake Warning Light
This light monitors various brake functions,
including brake fluid level and parking brake
application. If the brake light turns on it may
indicate that the parking brake is applied, that
the brake fluid level is low, or that there is a problem with
the Anti-lock Brake System reservoir.
If the light remains on when the parking brake has been
disengaged, and the fluid level is at the full mark on the
master cylinder reservoir, it indicates a possible brake

The blower fan speed can be set to any fixed speed by
adjusting the blower control. The fan will now operate at
a fixed speed until additional speeds are selected. This
allows the front occupants to control the volume of air
circulated in the vehicle and cancel the Auto mode.
The operator can also select the direction of the airflow
by selecting one of the available mode settings. A/C
operation and Recirculation control can also be manually
selected in Manual operation.
NOTE:Each of these features operates independently
from each other. If any feature is controlled manually,
temperature control will continue to operate automati-
cally.
Operating Tips
NOTE: Refer to the chart at the end of this section for
suggested control settings for various weather condi-
tions.
Summer Operation
The engine cooling system must be protected with a
high-quality antifreeze coolant to provide proper corro-
sion protection and to protect against engine overheating.
OAT coolant (conforming to MS.90032) is recommended.
Refer to “Maintenance Procedures” in “Maintaining Your
Vehicle” for proper coolant selection.
Winter Operation
To ensure the best possible heater and defroster perfor-
mance, make sure the engine cooling system is function-
ing properly and the proper amount, type, and concen-
tration of coolant is used. Refer to “Maintenance
Procedures” in “Maintaining Your Vehicle” for proper
coolant selection. Use of the air Recirculation mode
during Winter months is not recommended because it
may cause window fogging.
