If this light fails to illuminate
when you switch the ignition on,
continues to flash or remains on,
it indicates a malfunction. Have the system
checked by your authorized dealer. A tone
sounds when there is a malfunction.
Anti-Lock Braking System If it illuminates when you are
driving, this indicates a
malfunction. You will continue
to have the normal braking system
(without ABS) unless the brake system
warning lamp is also illuminated. Have the
system checked by your authorized dealer.
Battery If it illuminates while driving, it
indicates a malfunction. Switch
off all unnecessary electrical
equipment and have the system checked
by your authorized dealer immediately.
Brake System WARNING: Driving your vehicle with
the warning lamp on is dangerous. A
significant decrease in braking
performance may occur. It may take you
longer to stop your vehicle. Have your
vehicle checked as soon as possible.
Driving extended distances with the
parking brake engaged can cause brake
failure and the risk of personal injury. It illuminates when you engage
the parking brake and the
ignition is on. If it illuminates when your vehicle is
moving, make sure the parking brake is
disengaged. If the parking brake is
disengaged, this indicates low brake fluid
level or a brake system fault. Have your
vehicle checked immediately.
Charging System It illuminates when the battery
is not charging properly.
If it stays on while the engine is
running , there may be a malfunction with
the charging system. Contact your
authorized dealer as soon as possible. This
indicates a problem with the electrical
system or a related component.
Cruise Control (If Equipped) It illuminates when you switch
the system on.
See
Using Cruise Control
(page 187).
Directional Indicator Illuminates when you switch on
the left or right or the hazard
warning flasher. If the indicators
stay on or flash faster, check for a burned
out bulb. See Changing a Bulb (page 260).
Door Ajar Displays when the ignition is on
and any door is not completely
closed.
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.

XXX mi (km) to empty
Shows approximate fuel level before the
fuel tank reaches empty. The value is
dynamic and can change (raise or lower)
depending on driving style.
Fuel gauge
Switch the ignition on. The fuel gauge will
indicate approximately how much fuel is
in the fuel tank. The arrow next to the fuel
pump symbol shows the fuel filler door
side of your vehicle. When the fuel level
becomes low, the level indicator will
change to amber. When the fuel level
becomes critically low, the level indicator
will change to red.
Note: The fuel gauge level may vary slightly
when your vehicle is moving or when driving
on a slope.
Note: When a MyKey® is in use, low fuel
warnings will display earlier. Round 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. During SelectShift
Automatic
™ transmission (SST) use, the
currently selected gear will appear in the
display.
Engine coolant temperature gauge
Indicates engine coolant temperature. At
normal operating temperature, the level
indicator will be in the normal range. If the
engine coolant temperature exceeds the
normal range, stop your vehicle as soon as
safely possible, switch off the engine and
let the engine cool.

The heater acts as a starting aid by
warming the engine coolant. This allows
the climate control system to respond
quickly. The equipment includes a heater
element (installed in the engine block) and
a wire harness. You can connect the
system to a grounded 120-volt AC
electrical source.
We recommend that you do the following
for a safe and correct operation:
•
Use a 16-gauge outdoor extension cord
that is product certified by
Underwriter ’s Laboratory (UL) or
Canadian Standards Association
(CSA). This extension cord must be
suitable for use outdoors, in cold
temperatures, and be clearly marked
Suitable for Use with Outdoor
Appliances. Do not use an indoor
extension cord outdoors. This could
result in an electric shock or become a
fire hazard.
• Use as short an extension cord as
possible.
• Do not use multiple extension cords.
• Make sure that when in operation, the
extension cord plug and heater cord
plug connections are free and clear of
water. This could cause an electric
shock or fire.
• Make sure your vehicle is parked in a
clean area, clear of combustibles.
• Make sure the heater, heater cord and
extension cord are firmly connected.
• Check for heat anywhere in the
electrical hookup once the system has
been operating for approximately 30
minutes. •
Make sure the system is unplugged and
properly stowed before starting and
driving your vehicle. Make sure the
protective cover seals the prongs of the
block heater cord plug when not in use.
• Make sure the heater system is
checked for proper operation before
winter.
Using the Engine Block Heater
Make sure the receptacle terminals are
clean and dry prior to use. Clean them with
a dry cloth if necessary.
The heater uses 0.4 to 1.0 kilowatt-hours
of energy per hour of use. The system does
not have a thermostat. It achieves
maximum temperature after
approximately three hours of operation.
Using the heater longer than three hours
does not improve system performance and
unnecessarily uses electricity.

ENGINE COOLANT CHECK
WARNING: Do not remove the
coolant reservoir cap when the engine is
on or the cooling system is hot. Wait 10
minutes for the cooling system to cool
down. Cover the coolant reservoir cap with
a thick cloth to prevent the possibility of
scalding and slowly remove the cap.
Failure to follow this instruction could
result in personal injury. WARNING: Do not put coolant in the
windshield washer reservoir. If sprayed on
the windshield, coolant could make it
difficult to see through the windshield. WARNING:
To reduce the risk of
personal injury, make sure the engine is
cool before unscrewing the coolant
pressure relief cap. The cooling system is
under pressure. Steam and hot liquid can
come out forcefully when you loosen the
cap slightly. WARNING:
Do not add coolant
further than the MAX mark.
When the engine is cold, check the
concentration and level of the coolant at
the intervals listed in the scheduled
maintenance information. See Scheduled
Maintenance
(page 442).
Note: Make sure that the coolant level is
between the
MIN and MAX marks on the
coolant reservoir.
Note: Coolant expands when it is hot. The
level may extend beyond the
MAX mark. Maintain coolant concentration within
48% to 50%, which equates to a freeze
point between
-29°F (-34°C) and -35°F
(-37°C). Coolant concentration should be
checked using a refractometer. We do not
recommend the use of hydrometers or
coolant test strips for measuring coolant
concentration.
Adding Coolant WARNING:
Do not add engine
coolant when the engine is hot. Failure to
follow this instruction could result in
personal injury. WARNING:
Do not remove the
coolant reservoir cap when the engine is
on or the cooling system is hot. Wait 10
minutes for the cooling system to cool
down. Cover the coolant reservoir cap with
a thick cloth to prevent the possibility of
scalding and slowly remove the cap.
Failure to follow this instruction could
result in personal injury. WARNING: Do not put coolant in the
windshield washer reservoir. If sprayed on
the windshield, coolant could make it
difficult to see through the windshield.
Note: Do not use stop leak pellets, cooling
system sealants, or non-specified additives
as they can cause damage to the engine
cooling or heating systems. Resulting
component damage may not be covered by
the vehicle Warranty.
Note: Automotive fluids are not
interchangeable.
