Operation Characteristic
VEHICLE STARTS CONTROL
- At the start, torque distribution for front and rear wheels is fixed by electric control and stable start is achieved.
- Makes possible stable driving, with no wheel spin, on snowy roads or other slippery surfaces.
NORMAL CONTROL
- On roads which do not require AWD, it contributes to improved fuel economy by driving in conditions close to rear-wheel drive and it results in better fuel efficiency and provides FR-like steering characteristics.
- When spin occurs on rear wheel, distribute optimum torque to front wheel and keep stable driving.
- The vehicle cornering status is judged according to information from each sensor, and the optimum torque is distributed to front wheels for preventing tight cornering/braking symptom.
AWD WARNING LAMP INDICATION CONDITION
- Turns ON when there is a malfunction in AWD system. AWD warning lamp indicates the vehicle is in fail-safe mode.
- Also turns ON when ignition switch is turned ON, for the purpose of lamp check. Turns OFF approximately for 1 second after the engine starts if system is normal.
AWD WARNING LAMP INDICATION
| Condition | AWD warning lamp |
|---|---|
| Lamp check | Turns ON when ignition switch is turned ON. (Turns OFF approx. 1 second after the engine start.) |
| AWD system malfunction | ON |
| Protection function is activated due to heavy load to electric controlled coupling. (AWD system is not malfunctioning and AWD system changes to rear wheel drive.) | Quick blinking: 2 times/second (Blinking in approx. 1 minute and then turning OFF) |
| Large difference in diameter of front/rear tires | Slow blinking: 1 time/2 seconds (Continuing to blink until turning ignition switch OFF) |
| Other than above (system normal) | OFF |
CAUTION:
AWD warning lamp also turns ON due to data reception error, CAN communication error etc.
