NOTE
During headway control travel, the system accelerates and decelerates your vehicle
in conjunction with the speed of the vehicle ahead. However, if it is necessary to
accelerate for a lane change or if the vehicle ahead brakes suddenly causing you to
close in on the vehicle rapidly, accelerate using the accelerator pedal or decelerate
using the brake pedal depending on the conditions.
While the Mazda Radar Cruise Control (MRCC) system is in use, it does not cancel
even if the selector lever (automatic transaxle)/shift lever (manual transaxle) is
operated and any intended engine braking will not occur. If deceleration is required,
lower the vehicle speed setting or depress the brake pedal.
The brake lights are illuminated while the Mazda Radar Cruise Control (MRCC)
automatic braking is operating, however, they may not be illuminated while the
vehicle is on a down slope at the set vehicle speed or travelling at a constant speed and
following a vehicle ahead.
The Mazda Radar Cruise Control (MRCC) warning light (amber) illuminates when the
system has a malfunction.
Refer to Warning Lights on page 4-38 .
The headway control operation can be cancelled and the system can be switched to
only cruise control. Refer to Cruise Control Function on page 4-145 .
