Provides steering input to help keep the vehicle in the middle of a detected lane and
provides audible and visual alerts if the vehicle is detected drifting out of its lane.1Lane Keeping Assist System (LKAS)*
Important Safety Reminders
The LKAS is for your convenience only. It is not a
substitute for your vehicl e control. The system does
not work if you take y our hands off the steering
wheel or fail to steer the vehicle.
2 Multi-Information Display Warning and
Information Messages P. 93
Do not place objects on the instrument panel.
Objects may reflect on th e front windshield and
prevent correct detectio n of the traffic lanes.
LKAS only alerts you when lane drift is detected
without a turn signal in use. LKAS may not detect all
lane markings or lane departures; a ccuracy will vary
based on weather, speed, an d lane marker condition.
It is always your responsibility to safely operate the
vehicle and avoid collisions.
The LKAS is convenient when it is used on freeways.
The LKAS may not work properly or may work
improperly under the certain conditions: 2 LKAS Conditions and Limitations P. 309
Beeps and a warning display alert you
that the vehicle is drifting out of a
detected lane.
When you operate the turn signals to chan ge lanes, the system is suspended, and
resumes after the signals are off.
If you make a lane change without operat ing the turn signals, the LKAS alerts
activate, and torque is applied to the steering.
