▼ Engine Coolant Temperature Gauge
Displays the engine coolant temperature.
The blue gauge indicates that the engine
coolant temperature is low, and the red
gauge indicates that the engine coolant
temperature is high and overheating.
CAUTION
When the engine coolant temperature
gauge needle is in the red range, the engine
coolant temperature is extremely high.
Drive slowly to reduce engine load. If the
engine coolant temperature gauge needle
is in the red range, there is the possibility of
overheating. Park the vehicle in a safe
place immediately and take appropriate
measures.
Refer to Overheating on page 7-20.
NOTE
If the engine or engine coolant

temperature is high or low, the engine
output may be restricted to protect the
engine.
During normal driving, the engine

coolant temperature stabilizes at 100 °C
(210 °F) or less, and the gauge indicates
a range lower than 100 °C (210 °F).
Instrument Cluster and Display
▼ Fuel Gauge
The fuel gauge shows approximately how
much fuel is remaining in the tank when
the ignition is switched ON. We
recommend keeping the tank over 1/4 full.
1. Full
2. 1/4 Full
3. Empty
If the low fuel warning light illuminates or
the fuel level is very low, refuel as soon as
possible.
Refer to Low Fuel Warning Indication/
Warning Light on page 7-33.
NOTE
After refueling, it may require some time

for the indicator to stabilize. In addition,
the indicator may deviate while driving
on a slope or curve since the fuel moves
in the tank.
