Engine coolant temperature:
Illuminates when the engine coolant
temperature is high. Stop the
vehicle as soon as possible, switch off the engine and let cool. Refer to
Engine coolantin theMaintenance and Specificationschapter.
WARNING:Never remove the coolant reservoir cap while the
engine is running or hot.
Low tire pressure warning:
Illuminates when your tire pressure
is low. If the light remains on at
start up or while driving, the tire
pressure should be checked. Refer
toInflating your tiresin theTires, Wheels and Loadingchapter. When
the ignition is first turned to on, the light will illuminate for three
seconds to ensure the bulb is working. If the light does not turn on,
contact your authorized dealer as soon as possible. For more information
on this system, refer toTire pressure monitoring system (TPMS)in
theTires, Wheels and Loadingchapter.
AdvanceTrac/traction control
active:Flashes when the traction
control is active. If the light remains
on a malfunction has been detected;
contact your authorized dealer as
soon as possible. Refer to theDrivingchapter for more information.
AdvanceTrac/traction control
off light:Illuminates when the
traction control has been disabled
(by the driver or as a result of a
system failure). Refer to the
Drivingchapter for more
information.
Low fuel (if equipped):
Illuminates when the fuel level in
the fuel tank is at or near empty.
Refer toFuel gaugein this chapter.

1.Speedometer:Indicates the current vehicle speed.
2.Fuel gauge:Indicates approximately how much fuel is left in the fuel
tank (when the ignition is in the on position). The fuel gauge may vary
slightly when the vehicle is in motion or on a grade. The fuel icon and
arrow indicates which side of the vehicle the fuel filler door is located.
3.Engine coolant temperature gauge:Indicates engine coolant
temperature. At normal operating temperature, the needle will be in the
normal range (between H and C).If it enters the red section, the
engine is overheating. Stop the vehicle as soon as safely possible,
switch off the engine and let the engine cool.
4.Tachometer:Indicates the engine speed in revolutions per minute.
Driving with your tachometer pointer continuously at the top of the scale
may damage the engine.
5.Engine oil pressure gauge (optional V6 and GT cluster only):
Indicates engine oil pressure. The needle should stay in the normal
operating range (between L and H). If the needle falls below the normal

ENGINE BLOCK HEATER (IF EQUIPPED)
An engine block heater warms the engine coolant which aids in starting
and allows the heater/defroster system to respond quickly. If your vehicle
is equipped with this system, your equipment includes a heater element
which is installed in your engine block and a wire harness which allows
the user to connect the system to a grounded 120 volt A/C electrical
source. The block heater system is most effective when outdoor
temperatures reach below 0°F (-18°C).
WARNING:Failure to follow engine block heater instructions
could result in property damage or physical injury.
WARNING:To reduce the risk of electrical shock, do not use
your heater with ungrounded electrical systems or two-pronged
(cheater) adapters.
Prior to using the engine block heater, follow these recommendations for
proper and safe operation:
•For your safety, use an outdoor extension cord that is product
certified by Underwriter’s Laboratory (UL) or Canadian Standards
Association (CSA). Use only an extension cord that can be used
outdoors, in cold temperatures, and is clearly marked “Suitable for Use
with Outdoor Appliances.” Never use an indoor extension cord
outdoors; it could result in an electric shock or fire hazard.
•Use a 16-gauge outdoor extension cord, minimum.
•Use as short an extension cord as possible.
•Do not use multiple extension cords. Instead, use one extension cord
which is long enough to reach from the engine block heater cord to
the outlet without stretching.
•Make certain that the extension cord is in excellent condition (not
patched or spliced). Store your extension cord indoors at
temperatures above 32°F (0°C). Outdoor conditions can deteriorate
extension cords over a period of time.
•To reduce the risk of electrical shock, do not use your heater with
ungrounded electrical systems or two pronged (cheater) adapters.
Also ensure that the block heater, especially the cord, is in good
condition before use.
•Make sure that when in operation, the extension cord plug/engine
block heater cord plug connection is free and clear of water in order
to prevent possible shock or fire.

ENGINE COOLANT
Checking engine coolant
The concentration and level of engine coolant should be checked at the
intervals listed inscheduled maintenance information.The coolant
concentration should be maintained at 50/50 coolant and distilled water,
which equates to a freeze point of -34°F (-36°C). Coolant concentration
testing is possible with a hydrometer or antifreeze tester. The level of
coolant should be maintained at the FULL COLD level or within the
COLD FILL RANGE in the coolant reservoir. If the level falls below, add
coolant per the instructions in theAdding engine coolantsection.
Your vehicle was factory-filled with a 50/50 engine coolant and water
concentration. If the concentration of coolant falls below 40% or above
60%, the engine parts could become damaged or not work properly.A
50/50 mixture of coolant and water provides the following:
•Freeze protection down to -34°F (-36°C).
•Boiling protection up to 265°F (129°C).
•Protection against rust and other forms of corrosion.
•Proper function of calibrated gauges.
When the engine is cold, check the
level of the engine coolant in the
reservoir.
•The engine coolant should be at the FULL COLD level, or within the
COLD FILL or MIN / MAX range as listed on the engine coolant
reservoir (depending upon application).
•Refer toscheduled maintenance informationfor service interval
schedules.
If the engine coolant has not been checked at the recommended interval,
the engine coolant reservoir may become low or empty. If the reservoir is
low or empty, add engine coolant to the reservoir. Refer toAdding
engine coolantin this chapter.
Note:Automotive fluids are not interchangeable; do not use engine
coolant/antifreeze or windshield washer fluid outside of its specified
function and vehicle location.
