The Lexus Safety System Plus+, is a state-of-the-art safety package designed to help
prevent collisions in a wide range of vehicle speeds.
The system includes Lane Departure Alert, Automatic High beam, Pedestrian Pre-
Collision System and Dynamic Radar Cruise Control.
Lexus Dynamic Radar Cruise Control supplements conventional cruise control with a
vehicle-to-vehicle distance control system.
It enables the vehicle to automatically adjust the speed to maintain a safe following
distance with the vehicle ahead.
The system uses a radar sensor mounted at the front of the vehicle to determine the
distance from the vehicle ahead. Its important to keep the sensor and grille clean to
ensure the system can operate properly.
The radar sensor detects the presence of vehicles up to about 120 metres (or 400 feet) ahead.
It determines the correct vehicle-to-vehicle following distance and then maintains a
suitable distance behind that vehicle.
The controls work the same way as a conventional cruise control system, such as
setting, adjusting, and canceling the set speed.
There is an additional distance control button on the steering wheel for setting the
desired vehicle-to-vehicle distance to be maintained.
Three choices are available - long, medium, and short. They can be selected by
repeatedly pressing the distance control button.
The selected distance is shown in the multi-information display along with the set speed.
The long position is automatically selected each time the ignition is turned on.
When driving at speeds of 80 km/h, the long setting results in a following distance of
approximately 50 metres (or 160 feet) from the vehicle ahead.
With the medium setting, that distance is reduced to approximately 40 metres (or 130 feet).
And with the short setting, its approximately 30 metres (or 100 feet.)
The vehicle-to-vehicle distances increase or decrease proportionally with vehicle speed
and may increase or decrease on long grades.
When there is a vehicle ahead within the set range, a vehicle ahead symbol illuminates
in the cruise control indicator and the vehicle maintains the pre-set distance behind it as
it slows down or speeds up to a maximum of the speed set for the cruise control.
On some models, if the vehicle speed falls below approximately 40 km/h the vehicle-to-
vehicle distance control driving is automatically cancelled.
When approaching a slow moving vehicle or another vehicle cuts into the set space
from the vehicle ahead, a warning tone may sound and a warning appears in the multi-
information display to alert the driver to brake.
Some Lexus models will apply the brakes initially but will not bring the vehicle to a
complete stop. Other models can stop the vehicle automatically in certain situations
without the driver depressing the brake pedal.
When the vehicle is stopped by the system control, the vehicle-to- vehicle distance will
be between three and five meters (or 10-16 feet), depending on the model.
To resume the vehicle-to- vehicle setting, push the cruise control lever up or depress the
throttle after the vehicle ahead starts off.
The vehicle-to-vehicle distance control may automatically cancel if it detects inclement
weather such as rain, snow, or fog.
The cruise control function can also canceled by applying the brakes, moving the cruise
control stalk on the steering column to cancel, pressing the main cruise control on/ off
switch or shifting from drive to neutral.
If you prefer to use the traditional cruise control instead of the vehicle-to- vehicle
distance system you can. Simply push the cruise control stalk forward after setting your
desired speed. Keep in mind, the driver is now exclusively responsible for maintaining
the appropriate distance between other vehicles.
Dynamic Radar Cruise Control is not a collision- avoidance system or a substitute for
safe and attentive driving practices.
