vehicle from empty indication, the amount of fuel that can be added will
be less than the advertised capacity due to the reserve fuel.
A minimum of 22.2 L (six gallons) must be added or removed from the
fuel tank in order for the gauge to instantaneously update. If less than
six gallons is the change, the gauge will take between five to twenty
minutes to update.
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. If the gauge enters the red section, the oil
pressure/engine coolant and Check Engine/Service Engine Soon
indicators illuminate, refer to What you should know about fail-safe
cooling in the Maintenance and care chapter.
