Engine Oil Pressure Gauge
Indicates engine oil pressure. The needle
should stay in the normal operating range
(between L and H). If the needle falls
below the normal range, stop the vehicle,
turn off the engine and check the engine
oil level. Add oil if needed. If the oil level is
correct, have your vehicle checked by your
authorized dealer.
Engine Coolant Temperature
Gauge
WARNING
Never remove the coolant reservoir
cap while the engine is running or hot.
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 the vehicle as soon as
safely possible, switch off the engine and
let the engine cool.
Transmission Fluid Temperature
Gauge
Indicates transmission fluid temperature.
At normal operating temperature, the level
indicator will be in the normal range. If the
transmission fluid temperature exceeds
the normal range, stop the vehicle as soon
as safely possible and verify the airflow is
not restricted such as snow or debris
blocking airflow through the grill. Also,
higher than normal operating temperature
can be caused by special operation
conditions (i.e. snowplowing, towing or
off-road use). Refer to Special operating
conditions in the scheduled maintenance
information for instructions. Operating the transmission for extended periods of time
with the gauge in the higher than normal
area may cause internal transmission
damage. Altering the severity of the driving
conditions is recommended to lower the
transmission temperature into the normal
range. If the gauge continues to show high
temperatures, see your authorized dealer.
Fuel Gauge
Note:
The fuel gauge may vary slightly
when your vehicle is moving or on a gradient.
Switch the ignition on. The fuel gauge will
indicate approximately how much fuel is
left in the fuel tank. The arrow adjacent to
the fuel pump symbol indicates on which
side of your vehicle the fuel filler door is
located.
The needle should move toward F when
you refuel your vehicle. If the needle points
to E after adding fuel, this indicates your
vehicle needs service soon.
After refueling some variability in needle
position is normal:
• It may take a short time for the needle
to reach F after leaving the gas station.
This is normal and depends upon the
slope of pavement at the gas station.
• The fuel amount dispensed into the
tank is a little less or more than the
gauge indicated. This is normal and
depends upon the slope of pavement
at the gas station.
• If the gas station nozzle shuts off
before the tank is full, try a different
gas pump nozzle.
Low Fuel Reminder
A low fuel reminder triggers when the fuel
gauge needle is at 1/16th.

WARNING
Driving your vehicle with the warning
lamp on is dangerous. A significant
decrease in braking performance
may occur. It will take you longer to stop
your vehicle. Have your vehicle checked by
your authorized dealer immediately. Driving
extended distances with the parking brake
engaged can cause brake failure and the
risk of personal injury. Check Fuel Cap (If Equipped)
Illuminates when the fuel cap
may not be properly installed.
Continued driving with this light
on may cause the Service engine
soon warning indicator to come on.
Cruise Control
(If Equipped) Illuminates when you switch this
feature on. See
Using Cruise
Control (page 178).
Direction Indicator Illuminates when the left or right
turn signal or the hazard warning
flasher is turned on. If the
indicators stay on or flash faster, check for
a burned out bulb.
Door Ajar Displays when the ignition is on
and any door is not completely
closed.
Electronic Locking Differential Illuminates when using the
electronic locking differential. 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.
Engine Oil If it illuminates with the engine
running or when you are driving,
this indicates a malfunction.
Stop your vehicle as soon as it is safe to
do so and switch the engine off. Check the
engine oil level. See
Engine Oil Check
(page 235).
Note: Do not resume your journey if it
illuminates despite the level being correct.
Have the system checked by your authorized
dealer immediately.
Fasten Safety Belt It will illuminate and a chime will
sound to remind you to fasten
your safety belt.
Front Airbag If it fails to illuminate when you
start your vehicle, continues to
flash or remains on, it indicates
a malfunction. Have the system checked
by your authorized dealer.

Low Fuel Level
Illuminates when the fuel level
is low or the fuel tank is nearly
empty. Refuel as soon as
possible.
Low Tire Pressure Warning Illuminates when your tire
pressure is low. If the lamp
remains on with the engine
running or when driving, check
your tire pressure as soon as possible.
It will also illuminate momentarily when
you switch the ignition on to confirm the
lamp is functional. If it does not illuminate
when you switch the ignition on, or begins
to flash at any time, have the system
checked by your authorized dealer.
Powertrain Malfunction/Reduced
Power/Electronic Throttle Control Illuminates when a powertrain
or an AWD fault has been
detected. Contact your
authorized dealer as soon as possible.
Service Engine Soon If the service engine soon
indicator light stays illuminated
after the engine is started, it
indicates that the On-Board Diagnostics
(OBD-II) system has detected a
malfunction of the vehicle emissions
control system. Refer to On-Board
Diagnostics (OBD-II) in the Fuel and
Refueling chapter for more information
about having your vehicle serviced. See
Emission Control System (page 144). If the light is blinking, engine misfire is
occurring which could damage your
catalytic converter. Drive in a moderate
fashion (avoid heavy acceleration and
deceleration) and have your vehicle
serviced immediately. WARNING
Under engine misfire conditions,
excessive exhaust temperatures
could damage the catalytic
converter, the fuel system, interior floor
coverings or other vehicle components,
possibly causing a fire. Have an authorized
dealer service your vehicle immediately. The service engine soon indicator light
illuminates when the ignition is first turned
on prior to engine start to check the bulb
and to indicate whether the vehicle is ready
for Inspection/Maintenance (I/M) testing.
Normally, the service engine soon light will
stay on until the engine is cranked, then
turn itself off if no malfunctions are
present. However, if after 15 seconds the
service engine soon light blinks eight times,
it means that the vehicle is not ready for
I/M testing. See
Emission Control
System (page 144).
Stability Control Illuminates when the system is
active. If it remains illuminated
or does not illuminate when you
switch the ignition on, this indicates a
malfunction. During a malfunction the
system will switch off. Have the system
checked by your authorized dealer
immediately. See
Using Stability
Control (page 169).
