STARTING AND DRIVING
398
CAUTION
Under certain conditions where the vehicle in front
slows drastically, or is stopped, the dynamic radar
cruise control will neither warn you nor decelerate. The
driver must depress the brake pedal to slow down,
ensuring collision avoidance or that sufficient
vehicle−to−vehicle distance is maintained.
When vehicle−to−vehicle distance control mode is activated,
you must still be attentive to road and traffic conditions. Should
your vehicle speed decrease below about 40 km/h (25 mph),
the dynamic radar cruise control will shut off, requiring you to
apply the brakes to slow. When a vehicle ahead slows
suddenly, stops or a vehicle cuts in front, the system may slow
your vehicle abruptly, but the automatic braking will cease if the
speed decreases below about 40 km/h (25 mph) requiring the
driver’s manual application of brakes.
CAUTION
Certain conditions make vehicle detection difficult or
impossible.
As this system operates by detecting primarily the
reflected wave from the rear end of the vehicle ahead,
the distance cannot be accurately detected in the
following cases, resulting in improper
vehicle−to−vehicle distance.
♦The rear section of the vehicle ahead is extremely
small such as an unloaded trailer.
♦The vehicle ahead or other vehicles around you
are flinging up water or snow.
♦Heavy luggage which is loaded in your trunk or on
top of your rear seats is raising up the nose of your
vehicle.
The millimeter wave radar sensor automatically
detects dirt if it is sticking to the front of the sensor
or cover of your vehicle, and if detected, a message
appears on the multi−information display. However,
if the sensor or cover is covered with a metallic vinyl
bag, icicle, snowflakes, etc., dirt may not be detected,
resulting in improper vehicle−to−vehicle distance.
Continue driving with due care to the vehicle ahead.
If dirt is detected, the dynamic radar cruise control
function is automatically cancelled. Always keep the
sensor and cover clean.
