This meter shows the number of
miles (U.S.) or kilometers (Canada)
driven since you last reset it.
There are two trip meters: Trip A
and Trip B. Switch between these
displays by pressing the Select
button repeatedly. Each trip meter
works independently, so you can
keep track of two dif f erent distances.
When you turn the ignition switch
ON (II), what you last selected isdisplayed.
To reset a trip meter, display it, and
then press and hold the Reset button
until the number resets to ‘‘0.0’’.
Both trip meters will reset if the
vehicle’s battery goes dead or is
disconnected.
This shows the temperature of the
engine’s coolant. During normal
operation, the pointer should rise
from the bottom blue mark to about
the middle of the gauge. In severe
driving conditions, such as very hot
weather or a long period of uphill
driving, the pointer may rise to the
upper white mark. If it reaches the
red (Hot) mark, pull saf ely to the
side of the road. Turn to page f or
instructions and precautions on
checking the engine’s cooling
system.
This shows how much f uel you have.
It is most accurate when the vehicle
is on level ground. It may show
slightly more or less than the actual
amount when you are driving on
curvy or hilly roads.
The needle returns to the bottom
after you turn off the ignition. The
gauge shows the f uel level reading
immediately af ter you turn the
ignition switch back ON (II).
