Engine Oil Pressure Gauge
Indicates engine oil pressure. The needle
should stay in the normal operating range,
between the L and H marks. If the needle
falls below the normal range, stop your
vehicle, turn off the engine and check the
engine oil level. Add oil if needed. If the oil
level is correct and the gauge displays
incorrectly, have your vehicle checked by
an authorized dealer.
Engine Coolant Temperature
Gauge 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.
Indicates engine coolant temperature. At
normal operating temperature, the level
indicator is in the normal range. If the
engine coolant temperature exceeds the
normal range, stop your vehicle as soon as
possible, switch off the engine and let the
engine cool.
Fuel Gauge
The fuel gauge indicates about how much
fuel is 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.
Note: The fuel gauge may vary slightly
when your vehicle is moving or on a slope. Low Fuel Reminder
A low fuel level reminder displays and
sounds when the distance to empty
reaches
50 mi (80 km), 25 mi (40 km),
10 mi (20 km) and 0 mi (0 km).
Note: The low fuel reminder can appear at
different fuel gauge positions depending on
fuel economy conditions. This variation is
normal.
Distance to Empty
Indicates the approximate distance your
vehicle can travel on the fuel remaining in
the tank. Changes in driving pattern can
cause the value to not only decrease but
also increase or stay constant for periods
of time.
Configurable Gauge
Transmission Fluid Temperature Gauge
Indicates transmission fluid temperature.
At normal operating temperature, the level
indicator is in the normal range. If the
transmission fluid temperature exceeds
the normal range, stop your vehicle as soon
as possible and verify the airflow is not
restricted by snow or debris blocking
airflow through the grille.
To lower the transmission temperature
into the normal range, alter the severity of
your driving conditions. Operating the
transmission for extended periods with the
gauge in the higher than normal area may
cause internal transmission damage. If the
gauge continues to show high
temperatures, see an authorized dealer.
Voltmeter
Displays electrical system voltage.
