■When no vehicle is traveling ahead
If the vehicle detected ahead disappears from
the travel path of your vehicle (for example, it
changes lanes), Traffic Jam Assist will be
deactivated temporarily and your vehicle will
gradually accelerate until it reaches the set
speed, after which it will maintain that speed.1How Traffic Jam Assist Works
If the vehicle detected ahead suddenly slows down,
or if another vehicle is de tected cutting in front of
yours, a warning buzzer will sound, and a warning in
the driver information interface and head-up
warning
* will appear.
Depress the brake pedal and take direct control of
steering.
