 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 Contr ol (MRCC) system is in use, it does not cancel even
if the selector lever (automatic transaxle)/shift lever (manual trans\
axle) 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. The Mazda Radar Cruise Contr ol (MRCC) warning light (amber) illuminates when the
system has a malfunction.
Refer to Warning Lights on page 4-24. The headway contr ol operation can be canceled and the system can be switched to only
cruise control. Refer to Cruise Control Function on page 4-115.

uptly and the vehicle
moves close to a white (yellow) line, the system determines that the d\
river is making a lane
change and the Lane-keep Assist System (LAS) & Lane Departure Warning System (LDWS)
operation is temporarily canceled. The Lane-keep Assist System (LAS) & Lane Departure
Warning System (LDWS) becomes operational again when the system detects\
white (yellow)
