approximately 30 mph [50 km/h])
and press the “-SET” switch to set
the speed.
Cruise control “SET” indicator will come
on.
The vehicle speed at the moment the

speed is below approximately 30 mph (50
km/h) and a preceding vehicle is present,
the set speed will be adjusted to approxi- mately 30 mph (50 km/h).
To change the set speed, operate the

When your vehicle is too close to a
vehicle ahead, and sufficient automatic
deceleration via the cruise control is
not possible, the display will flash and
the buzzer will sound to alert the driver.
An example of this would be if another
driver cuts in front
of you while you are
following a vehicle. Depress the brake
pedal to ensure an appropriate vehi-
cle-to-vehicle distance.
