NOTE:The engine must be running for the heated seats
to operate.
The heated seats switch from High to Low and from Low
to Off automatically, based on time and temperature of
the seat. The heated seats can operate on High heat for as
little as 4 minutes and up to 30 minutes before switching
to Low heat. Once a seat has switched to the Low heat
setting it may operate for an additional 60 minutes before
automatically shutting Off. The heated seats can shut Off
early or may not turn on when the seat is already warm.
NOTE: The drivers heated seat can be programmed to
come on during a remote start. Refer to “Remote Starting
System — If Equipped” in Section 2 for further informa-
tion.WARNING!
•Persons who are unable to feel pain to the skin
because of advanced age, chronic illness, diabetes,
spinal cord injury, medication, alcohol use, ex-
haustion or other physical condition must exercise
care when using the seat heater. It may cause burns
even at low temperatures, especially if used for
long periods of time.
•Do not place anything on the seat that insulates
against heat, such as a blanket or cushion. This
may cause the seat heater to overheat.

CAUTION!
Driving with a hot engine cooling system could damage
your vehicle. If temperature gauge reads “H” pull over
and stop the vehicle. Idle the vehicle with the air
conditioner turned off until the pointer drops back into
the normal range. If the pointer remains on the “H” and
you hear continuous chimes, turn the engine off imme-
diately, and call an authorized dealership for service.
WARNING!
A hot engine cooling system is dangerous. You or others
could be badly burned by steam or boiling coolant. You
may want to call an authorized dealership for service if
your vehicle overheats. If you decide to look under the
hood yourself, see Section 7 of this manual. Follow the
warnings under the Cooling System Pressure Cap para-
graph.
5. Speedometer
The speedometer shows the vehicle speed in miles per
hour and/or kilometers per hour (mph/km/h).
6. 4 LOWThis light alerts the driver that the vehicle is in
the four-wheel drive LOW mode. The front and
rear driveshafts are mechanically locked to-
gether forcing the front and rear wheels to
rotate at the same speed. Low range provides a greater
gear reduction ratio to provide increased torque at the
wheels.
For more information on four-wheel drive operation and
proper use, refer to “Four-Wheel Drive Operation — If
Equipped” in section 5 of this manual.

to improve window clearing operation. Recirculation will
be disabled automatically if these modes are selected.
Summer Operation
The engine cooling system in air conditioned vehicles
must be protected with a high-quality antifreeze coolant
to provide proper corrosion protection and to protect
against engine overheating. A solution of 50% ethylene
glycol antifreeze coolant and 50% water is recommended.
Refer to “Maintenance Procedures” in Section 7 of this
manual 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

performance and reduce the potential for transmission
overheating or failure due to excessive shifting. When
operating in the TOW/HAUL mode, fifth gear is dis-
abled and 2-3 and 3-4 shift patterns are modified.
Shifts into Overdrive (fourth gear) are allowed during
steady cruise (for improved fuel economy) and automaticclosed-throttle downshifts to third gear are performed
(for improved braking) when driving conditions warrant.
The “TOW/HAUL Indicator Light” will illuminate in the
instrument cluster to indicate when the switch has been
activated. Pressing the switch a second time restores
normal operation. If the TOW/HAUL mode is desired,
the button must be pressed each time the engine is
started.
Torque Converter Clutch
A feature designed to improve fuel economy has been
included in the automatic transmission on your vehicle.
A clutch within the torque converter engages automati-
cally at calibrated speeds. This may result in a slightly
different feeling or response during normal operation in
the upper gears. When the vehicle speed drops or during
acceleration when the transmission downshifts to second
gear, the clutch automatically disengages.

allowed in the United States. MMT is prohibited in
Federal and California reformulated gasoline.
Materials Added To Fuel
All gasoline sold in the United States is required to
contain effective detergent additives. Use of additional
detergents or other additives is not needed under normal
conditions and would result in unnecessary cost. There-
fore, you should not have to add anything to the fuel.
Fuel System Cautions
CAUTION!
Follow these guidelines to maintain your vehicle’s
performance:
•The use of leaded gas is prohibited by Federal law.
Using leaded gasoline can impair engine perfor-
mance and damage the emission control system.(Continued)
CAUTION! (Continued)
•An out-of-tune engine or certain fuel or ignition
malfunctions can cause the catalytic converter to
overheat. If you notice a pungent burning odor or
some light smoke, your engine may be out of tune
or malfunctioning and may require immediate
service. Contact your authorized dealer for service
assistance.
•The use of fuel additives, which are now being
sold as octane enhancers are not recommended.
Most of these products contain high concentra-
tions of methanol. Fuel system damage or vehicle
performance problems resulting from the use of
such fuels or additives is not the responsibility of
the manufacturer.
NOTE: Intentional tampering with emissions control
systems can result in civil penalties being assessed
against you.5
