Highway Assist

This page shows every update released by Rivian where Highway Assist was featured or mentioned. The latest update is shown first.


In Adaptive Cruise Control (ACC) or Highway Assist (HWA), you can now select from the following Set Speed preferences:

Speed Limit: Sets the speed to the detected speed limit for the road (new default).

Current Speed: Sets the speed to the current vehicle speed at the time of engagement.

Driver+ now generates a preemptive warning when a reduction in lane line visibility prevents Highway Assist from sustaining performance.


Added a message that appears on the driver display before the vehicle reaches the maximum speed allowed for Highway Assist and disengages Highway Assist.


Improved lane centering robustness with better lane negotiation during Highway Assist.


Deactivated the driver monitoring camera. The deactivation of this interior camera does not impact the safety or functionality of your vehicle.

Improved Highway Assist (HWA) availability by no longer shutting it off during travel through overhead gantry electronic toll collection stations.

Fixed a rare issue that caused HWA to disengage upon engagement right after a lane change.

Fixed a rare issue that incorrect camera visibility notifications appear during cruise control in Towing Mode.

Fixed an issue that prevents a hands-off warning after HWA was activated at low speeds.

Fixed an issue that incorrectly issued a hands-off warning after Adaptive Cruise Control engagement.


Improved lane-centering performance for Highway Assist.

Fixed a rare issue that displayed an incorrect explanation of why Highway Assist wasn’t available.


Lowered frequency of Adaptive Cruise Control and Highway Assist disengagements by reducing front camera sensitivity to certain environments and lighting conditions, such as driving towards the sun or in rain.

Smoother lane centering performance on curvy roads while Highway Assist is engaged.


Highway Assist has been improved to reduce the frequency of hands-on warnings when Highway Assist is active in stop-and-go traffic scenarios. You still must remain attentive and should be prepared to take control of the vehicle at any time while Highway Assist is engaged. For more information, please see the Owner’s Guide.

Fixed a rare issue that caused inconsistent lane centering when Highway Assist was active.


Increased the Highway Assist hands-off warning time period from 10 to 20 seconds for your convenience.

Your vehicle now notifies you that the rear Park Assist warning isn’t available while the Rear accessory setting is enabled.

Reduce the time window from 2 seconds to 1 second to engage Highway Assist when you push the drive stalk twice. This enhances usability when you initiate Adaptive Cruise Control with the first push of the drive stalk, accelerate the vehicle to the desired speed, and then push the drive stalk again to set the higher speed.


Addressed certain cases where Highway Assist was unavailable due to errors related to Global Navigation Satellite System corrections.


Highway Assist improvement to more easily override automatic steering when you want to take over.

Addressed a rare issue when Highway Assist disengaged during heavy traffic conditions with low visibility of lane markings.

Improved Highway Assist availability on banked roads.


Improved the logic to reduce the occurrence of unnecessary Highway Assist driver takeover requests in response to short tunnels or overpasses

Improved ability to engage Adaptive Cruise Control when Highway Assist is unavailable

Decreased Adaptive Cruise Control and Highway Assist disengagements due to low traction situations


For your privacy, the driver monitoring camera is turned off when Highway Assist isn’t engaged.

Better Adaptive Cruise Control in-lane and Highway Assist lane centering during highway driving.

A chime that indicates Highway Assist isn’t available is now louder so it’s easier to hear.

A new chime indicates the immediate cancellation of Highway Assist.

An increased delay before the vehicle shifts to Reverse or Neutral after Highway Assist or Adaptive Cruise Control ends. This prevents unintended shifts.


Your Driver+ settings for Adaptive Cruise Control (ACC) / Highway Assist (HWA) distance, Forward Collision Warning Proximity settings, Lane Keeping Assist, Blind Sport Warning, Park Assist Audio Warnings, and Rear Cross-Traffic Warning will now persist across software updates and drive cycles.
