Tachometer
CAUTION
Do not operate the engine with the pointer of the tachometer in
the red zone. In this range, fuel injection will be cut by the enginecontrol module to protect the engine from overrevving. Theengine will resume running normally after the engine speed isreduced below the red zone.
The tachometer shows the engine speed in thousands of revolutions perminute. Outside temperature indicator (if equipped)
The outside temperature indicator shows the outside temperature in a
range from –22F to 122 F ( –30 C to 50 C).
The indicator can give a false reading under any of the following condi-tions: When there is too much sun.
During idling; while running at low speeds in a traffic jam; when the
engine is restarted immediately following a shutdown. When the actual outside temperature falls outside the specified indi-
cator range. For vehicles with an automatic climate control, outside temperature can be displayed on the climate control display panel. Refer to the“ Automatic climate control system ” in chapter 4.
Fuel gauge
The fuel gauge shows the approximate amount of fuel remaining in thetank.
The gauge does not return to “E” even though the ignition switch is in the
“ACC” or “LOCK” position.
The gauge may move slightly during braking, turning or acceleration dueto fuel level movement in the tank.
