Lane Keeping Assist System (Lkas); Collision Mitigation Braking System ™ (Cmbs ™ ) - Honda 2017 Acura RLX Owner's Manual

DRIVING

Lane Keeping Assist System (LKAS)*

Provides steering input to help keep the vehicle in the middle of a detected lane
and audible and visual alerts if the vehicle is detected drifting out of its lane while
driving between 45–90 mph (72–145 km/h).
If your vehicle is getting too close to detected left
or right side lane markings without a turn signal
activated, the steering wheel vibrates, a message
appears in the MID, and a beep sounds continuously.
The system also applies steering torque to keep the
vehicle in the middle of the lane. The applied torque
becomes stronger as the vehicle gets closer to either
of the lane lines.
Turning LKAS On or Off
1. Press MAIN. LKAS appears in the MID.
2. Press the LKAS button. Lane outlines appear
in the MID. Dotted lane lines turn solid when
the system operates.
3. Press MAIN or the LKAS button to turn the
system off.
Important Safety Reminder
The LKAS is for your convenience only. It is not a substitute for your vehicle control.
The system does not work if you take your hands off the steering wheel or fail to
steer the vehicle.
The LKAS only alerts you when lane drift is detected without a turn signal in use.
The LKAS may not detect all lane markings or lane departures; accuracy will vary
based on weather, speed, and lane marker condition.
It is always your responsibility to safely operate the vehicle and avoid collisions.

Collision Mitigation Braking System

determined while driving at 3 mph (5 km/h) or above, and reduce your vehicle
speed when a collision is deemed unavoidable to help minimize collision severity.

do not take appropriate action to avoid a collision.
If a collision with an oncoming vehicle is detected,
the system provides rapid vibrations on the steering
wheel in addition to the visual and audible alerts.

Changing Settings
See page 86 for how to change CMBS settings. Options include Long, Normal

prevent collision nor stop the vehicle automatically. It is still your responsibility to
operate the brake pedal and steering wheel appropriately according to the driving
conditions.
