To help enhance driving safety and performance, the following systems operate automatically in response to various driving situations.
Be aware, however, that these systems are supplementary and should not be relied upon too heavily when operating the vehicle.
- ABS (Anti-lock Brake System)
Helps to prevent wheel lock when the brakes are applied suddenly, or if the brakes are applied while driving on a slippery road surface.
- Brake assist
Generates an increased level of braking force after the brake pedal is depressed, when the system detects a panic stop situation.
- VSC (Vehicle Stability Control)
Helps the driver to control skidding when swerving suddenly or turning on slippery road surfaces
- TRAC (Traction Control)
Maintains drive power and prevent the front wheels (2WD models) or four wheels (AWD models) from spinning when starting the vehicle or accelerating on slippery roads.
- EPS (Electric Power Steering)
Employs an electric motor to reduce the amount of effort needed to turn the steering wheel.
- Enhanced VSC (Enhanced Vehicle Stability Control)
Provides cooperative control of the ABS, TRAC, VSC and EPS.
Helps to maintain directional stability when swerving on slippery road surfaces by controlling steering performance.
- Hill-start assist control
- Active Torque Control 4WD (if equipped)
Automatically switches from front-wheel drive to AWD (All- Wheel Drive) according to driving conditions, helping to ensure reliable handling and stability. Examples of conditions where the system will switch to AWD are when cornering, going uphill, starting off or accelerating, and when the road surface is slippery due to snow or rain etc.

Rear Occupant Classification Sensor LH Collision Detection (B1787)
DESCRIPTION
DTC B1787 is output when the occupant classification ECU receives a collision
detection signal sent by the rear occupant classification sensor LH if an accident
occurs.
DTC B1787 is also output when the front seat assembly RH is subjected to ...
Lost Communication with Rear Airbag Sensor LH (B1637/82,B1638/82,B1647/82,B1697/82,B1698/82)
DESCRIPTION
The side collision sensor LH circuit (to determine deployment of the front seat
side airbag assembly LH and curtain shield airbag assembly LH) is composed of the
center airbag sensor assembly, rear airbag sensor LH and side airbag sensor LH.
