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 system is
active. If the light remains on a
malfunction has been detected;
contact your authorized dealer as soon as possible. Refer to theDriving
chapter for more information.
AdvanceTrac/traction control
off light:Illuminates when the
system has been disabled (by the
driver or as a result of a system
failure). Refer to theDriving
chapter 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.

WARNING:If you smell exhaust fumes inside your vehicle, have
your dealer inspect your vehicle immediately. Do not drive if you
smell exhaust fumes.
Important ventilating information
If the engine is idling while the vehicle is stopped for a long period of
time, open the windows at least 1 inch (2.5 cm) or adjust the heating or
air conditioning to bring in fresh air.
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.

3. Run the engine until it reaches normal operating temperature.
4. Allow the engine to idle for at least one minute.
5. Turn the A/C on and allow the engine to idle for at least one minute.
6. Drive the vehicle to complete the relearning process.
•The vehicle may need to be driven 10 miles (16 km) or more to
relearn the idle and fuel trim strategy.
•If you do not allow the engine to relearn its idle trim, the idle
quality of your vehicle may be adversely affected until the idle
trim is eventually relearned.
When the battery is disconnected or a new battery installed, the
transmission must relearn its adaptive strategy. As a result of this, the
transmission may shift firmly. This operation is considered normal and
will not affect function or durability of the transmission. Over time the
adaptive learning process will fully update transmission operation to its
optimum shift feel.
If the battery has been disconnected or a new battery has been installed,
the clock and the preset radio stations must be reset once the battery is
reconnected.
•Always dispose of automotive
batteries in a responsible manner.
Follow your local authorized
standards for disposal. Call your
local authorized recycling center
to find out more about recycling
automotive batteries.
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.
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.
