Using assistance features safely

The features covered here are driver support systems. The driver remains responsible for steering, braking, and watching the road at all times.

• Keep hands on the wheel and eyes on the road.
• Expect systems to disengage without much warning.
• Learn how each feature hands control back to you.

Limitation: Marketing names can overstate capability. Read what the system actually does.

Heavy rain, fog, snow, low sun, and poorly marked roads are common reasons driver-assistance features become unavailable.

• An amber message often explains the system is temporarily limited.
• Radar may be affected by slush on the front of the vehicle.
• Cameras struggle with direct sunlight and darkness.

Limitation: Plan to drive without assistance whenever conditions are poor.

Before relying on any feature in a new or rental vehicle, take a few minutes to learn its controls in a safe, quiet place.

• Locate the steering wheel buttons for cruise and lane features.
• Check which features are enabled by default.
• Read the driver-assistance section of the owner's manual.

Limitation: Two vehicles with the same feature name may behave differently.
