Steering System Pull, Drift or Wander

NOTE: The EPAS system is designed to compensate for some steering issues (drift, pull, wander, etc.).
A vehicle-related drift or pull, on a flat road, can cause a consistent deviation from the straight-ahead path and require constant steering input in the opposite direction to counteract the effect.
- Drift or pull can be induced by conditions external to the vehicle, such as wind or road camber.
- Drift describes what a vehicle with this condition does with the hands off the steering wheel.
- Pull is described as a tugging sensation on the steering wheel felt by the driver, which must be overcome to keep the vehicle going straight.
- Wander is the tendency of the vehicle to require frequent, random left and right steering wheel corrections to maintain a straight path down a level road.
