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
specifications chapter.
Never remove the coolant reservoir cap while the engine is
running or hot. Steam and scalding liquid from a hot cooling
system can burn you badly.
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 specifications chapter.
Fuel gauge
Displays approximately how much
fuel is in the fuel tank. The fuel
gauge may vary slightly when the
vehicle is in motion or on a grade.
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.
If the key is left in the ON position during fueling, a minimum of 22.2 L
(six gallons) must be added to the fuel tank in order for the gauge to
instantaneously update. If less than six gallons is added, the gauge will
take between five to twenty minutes to update.
