If a problem is detected, the light will come on while
the engine is running. Cycle the ignition key when
the vehicle has completely stopped and the shift lever
is placed in the PARK position. The light should turn
off.
If the light remains lit with the engine running, your
vehicle will usually be drivable. However, see an
authorized dealer for service as soon as possible.
If the light is flashing when the engine is running,
immediate service is required. You may experience
reduced performance, an elevated/rough idle or en-
gine stall and your vehicle may require towing.
•Oil Temperature Warning Light
This telltale indicates engine oil temperature is
high. If the light turns on while driving, stop
the vehicle and shut off the engine as soon as
possible. •
Secondary Air Bag Warning Light
This telltale indicates the Passenger
Air Bag Disabled (PAD) [if equipped]

14. 4WD LOW Indicator Light — If Equipped
This light alerts the driver that the vehicle is in the
four-wheel drive LOW mode. The front and rear drive-
shafts are mechanically locked together forcing the front
and rear wheels to rotate at the same speed. Low range
provides a greater gear reduction ratio to provide in-
creased torque at the wheels.
For further information on four-wheel drive operation
and proper use, refer to “Four-Wheel Drive Operation —
If Equipped” in “Starting And Operating”.

15. SERV 4WD Indicator Light — If Equipped
This light alerts the driver that the 4WD is in need of
service. If this light is illuminated, see your authorized
dealer as soon as possible.
16. Temperature Gauge
The temperature gauge shows engine coolant tempera-
ture. Any reading within the normal range indicates that
the engine cooling system is operating satisfactorily.
The gauge pointer will likely indicate a higher tempera-
ture when driving in hot weather, up mountain grades,
or when towing a trailer. It should not be allowed to
exceed the upper limits of the normal operating range.
CAUTION!
Driving with a hot engine cooling system could
damage your vehicle. If the temperature gauge reads

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 immediately and call an autho-
rized dealer 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 dealer
for service if your vehicle overheats. If you decide to
look under the hood yourself, see “Maintaining Your
Vehicle”. Follow the warnings under the Cooling
System Pressure Cap paragraph.

Continuous driving with the Transmission Tempera-
ture Warning Light illuminated will eventually cause
severe transmission damage or transmission failure.
WARNING!
If you continue operating the vehicle when the
Transmission Temperature Warning Light is illumi-
nated you could cause the fluid to boil over, come in
contact with hot engine or exhaust components and
cause a fire.•Low Fuel Telltale

•Oil Pressure Warning Light
This light indicates low engine oil pressure. The
light should turn on momentarily when the
engine is started. If the light turns on while driving,
stop the vehicle and shut off the engine as soon as
possible. A chime will sound for four minutes when

Engine Oil Change Indicator System
Oil Change Required
Your vehicle is equipped with an engine oil change
indicator system. The “Oil Change Required” message
will display in the EVIC for five seconds after a single
chime has sounded, to indicate the next scheduled oil
change interval. The engine oil change indicator system
is duty cycle based, which means the engine oil change
interval may fluctuate, dependent upon your personal
driving style.
Unless reset, this message will continue to display each
time you turn the ignition switch to the ON/RUN
position or cycle the ignition to the ON/RUN position if
equipped with Keyless Enter-N-Go™. To turn off the
message temporarily, press and release the OK button.

To reset the oil change indicator system (after performing
the scheduled maintenance) refer to the following proce-
dure.
Vehicles Equipped With Keyless Enter-N-Go™
1. Without pressing the brake pedal, press the ENGINESTART/STOP button and cycle the ignition to the
ON/RUN position (do not start the engine.)
2. Fully depress the accelerator pedal, slowly, three times within 10 seconds.
3. Without pressing the brake pedal, press the ENGINE START/STOP button once to return the ignition to the
OFF/LOCK position.
NOTE: If the indicator message illuminates when you
start the vehicle, the oil change indicator system did not
reset. If necessary, repeat this procedure.Electronic Vehicle Information Center (EVIC)

E-85 Usage In Non-Flex Fuel Vehicles
Non-Flex Fuel Vehicles (FFV) are compatible with gaso-
line containing 10% ethanol (E10). Gasoline with higher
ethanol content may void the New Vehicle Limited
Warranty.
If a Non-FFV vehicle is inadvertently fueled with E-85
fuel, the engine will have some or all of these symptoms:
•Operate in a lean mode.
• OBD II “Malfunction Indicator Light” on.
• Poor engine performance.
• Poor cold start and cold drivability.
• Increased risk for fuel system component corrosion. To fix a Non-FFV vehicle inadvertently fueled once with
E-85 perform the following:
•
Drain the fuel tank (see your authorized dealer).
• Change the engine oil and oil filter.
• Disconnect and reconnect the battery to reset the
engine controller memory.
More extensive repairs will be required for prolonged
exposure to E-85 fuel.
MMT In Gasoline
Methylcyclopentadienyl Manganese Tricarbonyl (MMT)
is a manganese-containing metallic additive that is
blended into some gasoline to increase octane. Gasoline
blended with MMT provides no performance advantage
beyond gasoline of the same octane number without
