temperature display
2 Odometer / tripmeters / fuel reserve tripme-
ter / stopwatch
3 Shift timing indicator light
NOTE:
NOTE:Odometer, tripmeter, and stopwatch modes
Push the “SELECT” button to switch the display
between the odometer mode “ODO”, the trip-
meter modes “TRIP A” and “TRIP B” and the
stopwatch mode in the following order:
TRIP A TRIP B ODO Stopwatch
TRIP A
If the fuel level warning light comes on, the
odometer display will automatically change to
the fuel reserve tripmeter mode ”F-TRIP” and
start counting the distance traveled from that
point. In that case, push the ”SELECT” button to
switch the display between the various tripme-
ter, odometer, and stopwatch modes in the fol-
lowing order:
F-TRIP Stopwatch TRIP A TRIP B
ODO F-TRIP
To reset a tripmeter, select it by pushing the “SE-
LECT” button, and then push the “RESET” button
for at least one second. If you do not reset the fuel
reserve tripmeter manually, it will reset itself auto-
matically and the display will return to the prior
mode after refueling and traveling 5 km (3 mi).
Stopwatch mode
Standard measurement
1. Push the “RESET” button to start the stopwatch.
2. Push the “SELECT” button to stop the stopwatch.
3. Push the “SELECT” button again to reset the stopwatch.
Split-time measurement
1. Push the “RESET” button to start the stopwatch.
2. Push the “RESET” button to measure split-times. (The colon “:” will start flashing.)
3. Push the “RESET” button to display the final split-time or push the “SELECT” button to stop the stop-
watch and display total elapsed time.
4. Push the “SELECT” button to reset the stopwatch.
Coolant temperature display
The coolant temperature display indicates the temperature of the coolant. Push the “RESET” button to
switch the coolant temperature display to the air intake temperature display.
When the coolant temperature display is selected, “C” is displayed before the coolant temperature.
Air intake temperature display
The air intake temperature display indicates the temperature of the air drawn into the air filter case. Push
the “RESET” button to switch the coolant temperature display to the air intake temperature display.
Even if the air intake temperature is set to be displayed, the coolant temperature warning light comes
on when the engine overheats.
When the key is turned to “ON”, the coolant temperature is automatically displayed, even if the air
intake temperature was displayed prior to turning the key to “OFF”.
When the air intake temperature display is selected, “A” is displayed before thetemperature.

PERIODIC CHECKS AND ADJUSTMENTS
INTRODUCTION
This chapter includes all information necessary to perform recommended checks and adjustments. If
followed, these preventive maintenance procedures will ensure more reliable vehicle operation, a
longer service life and reduce the need for costly overhaul work. This information applies to vehicles
already in service as well as to new vehicles that are being prepared for sale, All service technicians
should be familiar with this entire chapter.
