GAUGES

Fuel gauge

Displays approximately how much
fuel is in the fuel tank (when the
ignition is in the ON position). The
fuel gauge may vary slightly when
the vehicle is in motion. The ignition
should be in the OFF position while
the vehicle is being refueled. When
the gauge first indicates empty,
there is a small amount of reserve
fuel in the tank. When refueling the
vehicle from empty indication, the amount of fuel that can be added will
be less than the advertised capacity due to the reserve fuel.

Speedometer

Indicates the current vehicle speed.

Engine coolant temperature gauge

Indicates the temperature of the
engine coolant. At normal operating
temperature, the needle remains
within the normal area (the area
between the “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 immediately and let the
engine cool. Refer to Engine
coolant in the Maintenance and
care chapter.

Never remove the coolant reservoir cap while the engine is
running or hot.

This gauge indicates the temperature of the engine coolant, not the
coolant level. If the coolant is not at its proper level the gauge indication
will not be accurate.

Odometer

Registers the total kilometers
(miles) of the vehicle.
