shown until the vehicle has trav-
eled a sufficient distance.
 The display units cannot be
switched between “km/L”, “L/100
km”, and “MPG” in this mode;
change to the instantaneous fuel
consumption mode first.
Coolant temperature
The temperature of the engine coolant
from 40 °C to 124 °C is shown in 1 °C
increments.
If the message “Hi” flashes, stop the
vehicle, then stop the engine and let it
cool. (See page 6-36.)
TIPWhen the coolant temperature is
below 40 °C, “Lo” will be dis-
played.
 The coolant temperature varies
with changes in the weather and
engine load.Air temperature
The temperature of the air drawn into
the intake system from –9 °C to 50 °C
is shown in 1 °C increments.TIP–9 °C will be displayed even if the
air temperature falls below –9 °C. 
The temperature displayed may
vary from the actual ambient tem-
perature.

and then back on again to cancel
the warning light. Failing to do so
will prevent the engine from start-
ing even though the engine will
crank when pushing the start
switch.
 an engine auto-stop system. The
engine stops automatically if left
idling for 20 minutes. If the engine
stops, simply push the start
switch to restart the engine.
