WARNING
Do not rely completely on the Mazda Radar Cruise Control (MRCC) system and always
drive carefully:
The Mazda Radar Cruise Control (MRCC) system is designed to reduce load on the
driver, and although it maintains a constant vehicle speed, or specifi cally, it maintains
a constant distance between your vehicle and the detected vehicle ahead according to
the vehicle speed, the system has detection limitations depending on the type of vehicle
ahead and its conditions, the weather conditions, and the road conditions. Additionally,
the system may be unable to decelerate suffi ciently to avoid hitting the vehicle ahead
if the vehicle ahead applies the brakes suddenly or another vehicle cuts into the driving
lane, which could result in an accident. Always verify the safety of the surrounding area
and depress the brake pedal or accelerator pedal while keeping a safer distance from
vehicles ahead or on-coming vehicles.
Do not use the Mazda Radar Cruise Control (MRCC) system in the following locations.
Otherwise, it could lead to an accident:
Roads with sharp curves and where vehicle traffi c is heavy and there is insuffi cient
space between vehicles. Roads where frequent and repetitive acceleration and
deceleration occur (Driving under these conditions using the Mazda Radar Cruise
Control (MRCC) system is not possible).
When entering and exiting interchanges, service areas, and parking areas of highways
(If you exit a highway while headway control is in use, the vehicle ahead will no longer
be tracked and your vehicle may accelerate to the set speed).
Slippery roads such as ice or snow-bound roads (The tires could spin causing you to
lose vehicle control).
Long descending slopes (to maintain distance between vehicles, the system
automatically and continuously applies the brakes which could result in the loss of
brake power).
For the purposes of safety, switch the Mazda Radar Cruise Control (MRCC) system off
when it is not being used.
CAUTION
If the vehicle is towed or you are towing something, switch the Mazda Radar Cruise
Control (MRCC) system off to prevent an incorrect operation.

expressways and other highways which do
not require a lot of repeated acceleration
and deceleration.
WARNING
Do not use the cruise control function in
the following locations:
Otherwise, it could lead to an accident.
Roads with sharp curves and where
vehicle traffi c is heavy and there is
insuffi cient space between vehicles.
(Driving under these conditions
using the cruise control function is
not possible)
Steep down slopes (Set speed may
be exceeded because suffi cient
engine braking cannot be applied)
Slippery roads such as ice or snow-
bound roads (Tires could spin
causing you to lose vehicle control)
Always drive carefully:
The warnings and brake control
will not operate after the headway
control function is canceled and the

Tire Pressure Monitoring System
*Some models.
Tire Pressure Monitoring System *
The Tire Pressure Monitoring System (TPMS) monitors the air pressure of all four tires. If
the air pressure of one or more tires is too low, the system warns the driver by indicating the
tire pressure monitoring system warning light in the instrument cluster and operating a beep
sound. The system monitors the tire pressures indirectly using the data sent from the ABS
wheel speed sensors.
To allow the system to operate correctly, the system needs to be initialized with the specifi ed
tire pressure (value on the tire pressure label). Follow the procedure and perform the
initialization.
Refer to Tire Pressure Monitoring System Initialization on page 4-153 .
The warning light fl ashes when the system has a malfunction.
