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.

Control item

Operation

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.

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.
