to P (Park), the vehicle turns off.
The DIC displays NO FOB, OFF OR RUN?, if the
keyless access transmitter is not detected inside the
vehicle when it is turned off.
SeeDIC Warnings and Messages on page 3-79for
more information.
Engine Coolant Heater
The engine coolant heater can provide easier starting
and better fuel economy during engine warm-up in cold
weather conditions at or below 0°F (−18°C). Vehicles with
an engine coolant heater should be plugged in at least
four hours before starting. Some models have an internal
thermostat in the cord which will prevent engine coolant
heater operation at temperatures above 0°F (−18°C).
To Use the Engine Coolant Heater
1. Turn off the engine.
2. Open the hood and unwrap the electrical cord.
For the 3.6L V6 and 4.4L V8 engine, the cord is
located in the front of the engine compartment,
on the passenger side of the vehicle.
For the 4.6L V8 engine, the cord is located in the
engine compartment on the driver side of the vehicle
near the inner fender and above the strut.
3. You must remove the plastic cap to access
the plug.
4. Plug it into a normal, grounded 110-volt AC outlet.
{CAUTION:
Plugging the cord into an ungrounded outlet could
cause an electrical shock. Also, the wrong kind of
extension cord could overheat and cause a re.
You could be seriously injured. Plug the cord into a
properly grounded three-prong 110-volt AC outlet.
If the cord will not reach, use a heavy-duty
three-prong extension cord rated for at least
15 amps.

Lane Departure Warning Light
For vehicles with the lane
departure warning system,
this light briey comes
on green, while starting
the vehicle, to indicate
that it is working.
If it does not, have the vehicle serviced by your
dealer/retailer. If the system is working normally the
indicator light will then go off.
This light also comes on green if the system detects a
left or right lane marking. It ashes, changes to amber
and three beeps sound if a detected lane marking is
crossed without using a turn signal. For more information,
see the Index in the Navigation Manual.
Engine Coolant Temperature
Warning Light
The engine coolant
temperature warning
light comes on when
the engine is very hot.
This light also comes on briey when the vehicle is
started.
If the light does not go out or comes on and stays on
while driving, there may be a problem with the cooling
system. Driving with engine coolant temperature light on
could cause the vehicle to overheat, seeOverheated
Engine Protection Operating Mode on page 5-36.
SeeEngine Overheating on page 5-34andDIC
Warnings and Messages on page 3-79for more
information.
3-64

Engine Coolant Temperature Gage
This gage shows
the engine coolant
temperature.
It can be used to see when the engine has warmed
up and to make sure the cooling system is operating
properly. If the gage pointer moves into the shaded area,
the engine coolant is too hot and the engine coolant
temperature warning light comes on. SeeEngine
Overheating on page 5-34for more information.
Tire Pressure Light
For vehicles with a tire
pressure light, this light
comes on briey when
the engine is started and
provides information about
tire pressures and the Tire
Pressure Monitoring
System.
When the Light is On Steady
This indicates that one or more of the tires is signicantly
underinated.
A tire pressure message in the Driver Information
Center (DIC), can accompany the light. SeeDIC
Warnings and Messages on page 3-79for more
information. Stop and check the tires as soon as it is
safe to do so. If a tire is underinated, inate to the
proper pressure. SeeTires on page 5-54for more
information.
3-65

COMPETITIVE DRIVING (STS-V Only)
This message displays when the competitive driving
mode is turned on with the TC (traction control) button.
The TC (traction control) light comes on when the
competitive driving mode is on. The Traction Control
System (TCS) will not operate while in competitive
driving mode. Adjust your driving accordingly. See
Competitive Driving Mode on page 4-11for more
information.

this message.
This message displays when the driver door is not
closed completely. Make sure that the door is closed
completely.
ENGINE COOLANT HOT IDLE ENGINE
Notice:If you drive your vehicle while the engine
is overheating, severe engine damage may occur.
If an overheat warning appears on the instrument
panel cluster and/or DIC, stop the vehicle as soon as
possible. Do not increase the engine speed above
normal idling speed. SeeEngine Overheating
on page 5-34for more information.
This symbol appears with
this message.
This message displays when the engine coolant
temperature is too hot. Stop and allow the vehicle
to idle until it cools down. SeeEngine Coolant
Temperature Warning Light on page 3-64.

ENGINE HOT – AC
(Air Conditioning) OFF
This message displays when the engine coolant
becomes hotter than the normal operating temperature.
SeeEngine Coolant Temperature Gage on page 3-65.
To avoid added strain on a hot engine, the air
conditioning compressor is automatically turned off.
When the coolant temperature returns to normal, the
air conditioning compressor turns back on. You can
continue to drive your vehicle.
If this message continues to appear, have the system
repaired by your dealer/retailer as soon as possible
to avoid damage to the engine.
ENGINE POWER REDUCED
This message displays when the engine power is being
reduced to protect the engine from damage. There could
be several malfunctions that might cause this message.
Reduced engine power can affect the vehicle’s ability to
accelerate. If this message is on, but there is no reduction
in performance, proceed to your destination. The
performance may be reduced the next time the vehicle
is driven. The vehicle may be driven at a reduced speed
while this message is on, but acceleration and speed may
be reduced. Anytime this message stays on, take the
vehicle to your dealer/retailer for service as soon as
possible.

Turn Signals When Towing a Trailer
The arrows on the instrument panel ash whenever
signaling a turn or lane change. Properly hooked up, the
trailer lamps also ash, telling other drivers the vehicle
is turning, changing lanes or stopping.
When towing a trailer, the arrows on the instrument
panel ash for turns even if the bulbs on the trailer
are burned out. For this reason you may think other
drivers are seeing the signal when they are not.
It is important to check occasionally to be sure the
trailer bulbs are still working.
The vehicle has bulb warning lights. When a trailer
lighting system is plugged into the vehicle’s lighting
system, its bulb warning lights may not let you know if
one of the lamps goes out. So, when the trailer lighting
system is plugged in, be sure to check the vehicle and
trailer lamps from time to time to be sure they are all
working. Once the trailer lamps are disconnected, the
bulb warning lights again can tell you if one of the vehicle
lamps is out.
Driving On Grades
Reduce speed and shift to a lower gearbeforestarting
down a long or steep downgrade. If the transmission is
not shifted down, the brakes might have to be used so
much that they would get hot and no longer work well.
On a long uphill grade, shift down and reduce the
vehicle’s speed to around 45 mph (70 km/h) to reduce
the possibility of the engine and the transmission
overheating.
Vehicles can tow in D (Drive). Shift the transmission to
a lower gear if the transmission shifts too often under
heavy loads and/or hilly conditions.
When towing at high altitude on steep uphill grades,
consider the following: Engine coolant will boil at a lower
temperature than at normal altitudes. If the engine is
turned off immediately after towing at high altitude on
steep uphill grades, the vehicle may show signs similar to
engine overheating. To avoid this, let the engine run while
parked, preferably on level ground, with the automatic
transmission in P (Park) for a few minutes before turning
the engine off. If the overheat warning comes on, see
Engine Overheating on page 5-34.
