METER ILLUMINATION CONTROL FUNCTION
• Combination meter controls meter illumination, based on the following signal.
- Position light request signal
• The combination meter switches mode between Daytime mode and Nighttime mode, according to the fol-
lowing conditions.
*: For further information, refer to
INL-9, "ILLUMINATION CONTROL SYSTEM : System Description"
.
BUCK LIGHT ILLUMINATION CONTROL FUNCTION
The operation of the illumination control switch allows the brightness adjustment of meter illumination.
METER ILLUMINATION ON/OFF CONTROL FUNCTION
• Combination meter turns ON meter illumination when the following condition is satisfied:
- Ignition switch ON
• Combination meter turns OFF meter illumination when any of the following condition is satisfied:
- During a crank with vehicle speed less than 1 km/h (0.6 MPH) and ACC power supply OFF
- Ignition switch OFF or ACC power supply OFF
• The combination meter receives the following signals to control meter illumination.

ENGINE-START EFFECT FUNCTION
When recognizing an engine start, the combination meter controls the following items for producing the effect.
• Speedometer
• Tachometer
• Each meter pointer illumination
• Meter illumination
• Information display illumination
• Shift position indicator (CVT models)
• Start-up illumination (M/T models)
Meter and Illumination Operations During Engine-start Effect
The combination meter controls the following items during the engine-start effect.
NOTE:
The pointers are stopped and illumination is turned off while cranking the engine.
Engine Start Judgement
The combination meter judges “engine-start” and activates the engine-start effect only once when the follow-
ing operational conditions are all satisfied.

Speedometer
Sweeps the pointer.
Tachometer
Sweeps the pointer.
Each meter pointer illumination
Turns on the illumination at the effect level.
Meter illumination
Increases the brightness to the effect level in stages.
Information display illumination
Turns on the illumination at the normal brightness level.
Shift position indicator (CVT models)
Turns ON at effect level brightness after staying OFF for 2
seconds.
Start-up illumination (M/T models)
Turns ON/OFF in stages between OFF and the effect level
brightness.

NOTE:
ENGINE-START EFFECT exits when any of the above operational conditions is cancelled during the engine-
start effect.
Signal Path
The combination meter judges “engine-start”, according to the following signals and activates the engine-start
effect function.
NOTE:
The engine-start effect function ends if any one of the above conditions is lost during the activation of this function.

INFORMATION DISPLAY : System Description
INFOID:0000000012201311
DESCRIPTION
• The combination meter receives signals necessary for controlling the operation of the information display
from each unit, sensor and switch.
• The combination meter incorporates a trip computer that displays the warning/information according to the
information received from each unit, sensor and switch.

• The combination meter shows the following functions on the information display.
- Odo/trip meter
- Fuel gauge
- Trip computer
- Interrupt indication
- Ambient temperature
ODO/TRIP METER
The combination meter calculates mileage, based on the following signals and displays the mileage on the
information display.
FUEL GAUGE
Control Outline
The combination meter reads the fuel level sensor signal from the fuel level sensor unit and indicates the fuel
level to the fuel gauge.
Refuel Control
The unit judges that the driver is refueling the vehicle and accelerates the fuel gauge segment movement if the
fuel level changes by 15 (4 US gal, 3 - 1/4 lmp gal) or more.
AMBIENT TEMPERATURE
The combination meter calculates ambient temperature based on the following signals, and the calculated
value is displayed on the information display.
NOTE:
• The indicated temperature is corrected based on an ignition signal, ambient temperature detected by the
ambient sensor, and vehicle speed signal. The indicated temperature is not raised under vehicle speed less
than 20 km/h (12 MPH).
• The ambient sensor input value that is displayed on “Data Monitor” of CONSULT is the value before the cor-
rection. It may not match the indicated temperature on the information display.
• Depending on engine heat or heat on the road surfaces, an ambient temperature may be indicated higher
than actual one.
TRIP COMPUTER
Current Fuel Consumption
The combination meter calculates current fuel consumption based on the following signals, and the calculated
value is displayed on the information display.
