Driving Aids
Adaptive Learning
The EPS system adaptive learning
helps correct for road irregularities
and improves overall handling and
steering feel. It communicates with
the vehicle's brake system to help
operate advanced stability control
and accident avoidance systems.
Additionally, whenever the battery is
disconnected or a new battery
installed, the vehicle must be driven
a short distance before the strategy
is relearned and all systems are
reactivated.
