How To About About Your Safety Alert Seat

If your vehicle has this available feature, Safety Alert Seat uses left-, right- or both-side driver seat vibration pulses to help you detect and identify the direction of potential crashes. You can also switch to beeping crash avoidance alerts.

How It Works

Small motors inside the seat will generate vibration pulses on the left, right or both sides of the bottom of the driver seat cushion when prompted by select Driver Assistance Technologies (see below). Along with visual alerts, these vibration pulses help to indicate the direction of certain detected threats or a situation that might require your attention. Note that Safety Alert Seat vibration pulses will replace audible beeps if you select “seat pulses” in the Alert Type menu.

Examples of Driver Assistance Technologies That Activate the Safety Alert Seat

Here are some of the available features that can activate Safety Alert Seat. Please note your vehicle may not have one or more of these features.

  1. Rear Cross Traffic Alert and Rear Cross Traffic Braking — Pulses the left or right side of the seat to indicate the direction of approaching cross traffic when in REVERSE
  2. Forward Collision Alert — Pulses both sides of the seat to warn of a possible collision with an object in front of the vehicle
  3. Rear Park Assist — Pulses both sides of the seat to warn of a possible collision with an object behind the vehicle when in REVERSE

Note: The types of alerts available vary by vehicle model.

Safety or driver assistance features are no substitute for the driver’s responsibility to operate the vehicle in a safe manner. The driver should remain attentive to traffic, surroundings and road conditions at all times. Visibility, weather, and road conditions may affect feature performance. Read the vehicle Owner's Manual for more important feature limitations and information.

For your security, please don’t include personal info such as phone number, address or credit card details.
