( → P.802)
Overtaking prevention function
If a detected vehicle in the passing lane is traveling slower than your vehicle,
overtaking will be suppressed.
The overtaking prevention function will not operate if the passing lane is congested or
vehicles are traveling at low speeds. This function is not available for vehicles without a
DCM.
Support for lane change
If your vehicle is being driven at approximately 80 km/h (50 mph) or more and
a lane change to the passing lane is performed, when the turn signal lever is
operated and the lane is changed, the vehicle will accelerate up to the set speed to
assist in overtaking.
For vehicles with a DCM: The system’s recognition of which lane is the passing lane is
determined by location information and the driving condition of surrounding vehicles. The
support for lane change function and overtaking prevention function may not operate if it is
difficult to obtain location information or there are few surrounding vehicles.
For vehicles without a DCM: The system’s recognition of which lane is the passing lane
may be based solely on the location of the steering wheel in the vehicle (left-hand drive/
right-hand drive). If the vehicle is driven in a location where the passing lane is on the
opposite side of that where the vehicle was originally sold, the vehicle may accelerate
when the turn signal lever is operated away from the passing lane. (e.g. The vehicle was
manufactured for a right-hand traffic location, but is being driven in a left-hand traffic
location. The vehicle may accelerate when the turn signal lever is operated to the right.)
If your vehicle is being driven at approximately 80 km/h (50 mph) or more and the lane is
changed to that with a vehicle traveling slower than your vehicle, when the turn signal lever
is operated the vehicle will gradually decelerate to assist in changing lanes.
Dynamic Radar Cruise Control with Road Sign Assist
Vehicles without a head-up display: When RSA function is enabled and the dynam-
ic radar cruise control system is operating, if a speed limit sign is detected, the
detected speed limit will be displayed with an up/down arrow. The set speed can
be increased/reduced to the detected speed limit by pressing and holding the
[+RES] switch or [ - ] switch.
Vehicles with a head-up display: When RSA function is enabled and the dynamic
radar cruise control system is operating, if a speed limit sign is detected, the
