Direct Adaptive Steering System
NEUTRAL POSITION STEERING WHEEL
- Check that steering gear assembly, steering column assembly and steering wheel are installed in the correct position.
- Check wheel alignment within specification. Refer to WHEEL ALIGNMENT : Service Data . (2WD) Refer to WHEEL ALIGNMENT : Service Data . (AWD).
- Set the vehicle to the straight-ahead position and confirm steering wheel is in the neutral position.
- If steering wheel is not in the neutral position. Refer to NVH Troubleshooting Chart .
STEERING WHEEL TURNING FORCE
- Park vehicle on a level and dry surface, set parking brake.
- Tires need to be inflated normal pressure. Refer to TIRE AIR PRESSURE : Service Data .
- Start engine.
- Check steering wheel turning force when steering wheel has been turned 360 deg. from neutral position.
Steering wheel turning force

: 185 mm (7.28 in)
FRONT WHEEL TURNING ANGLE
- Perform toe-in inspection. Refer to WHEEL ALIGNMENT : Service Data
. (2WD) Refer to WHEEL ALIGNMENT : Service Data
. (AWD).CAUTION: Perform front wheel turning angle inspection, after toe-in inspection.
- Place front wheels on turning radius gauges and rear wheels on stands, so that vehicle can be level.
- Check the maximum inner and outer wheel turning angles for LH and RH road wheels.
- Start the engine, and turn steering wheel from full left stop to full right stop and measure the turning angles (maximum inner wheel steering angle and maximum outer wheel steering angle).
A
: Inner wheel angle
B
: Outer wheel angle
Steering angle
: Refer to STEERING ANGLE : Service Data .
- Check the following items when turning angle is out of the standard.
- Perform toe-in adjustment. Refer to WHEEL ALIGNMENT : Service Data . (2WD) Refer to WHEEL ALIGNMENT : Service Data . (AWD).
- Steering angles are not adjustable. Check steering gear assembly, steering column assembly and front suspension components for wear or damage if any of the turning angles are different from the specified value. Replace any of them, if any non-standard condition exists.
- Start the engine, and turn steering wheel from full left stop to full right stop and measure the turning angles (maximum inner wheel steering angle and maximum outer wheel steering angle).
