▼Gate operator/Canadian
Programming
Canadian radio-frequency laws require
transmitter signals to “time-out” (or
quit) after several seconds of
transmission ― which may not be long
enough for HomeLink
to pick up the
signal during programming. Similar to
this Canadian law, some U.S. gate
operators are designed to “time-out”
in the same manner.

If you live in Canada or are having
di fficulties programming a gate
operator by using the programming
procedures (regardless of where you
live), replace Step 3 of Programming
the HomeLink System with the
following:
NOTE
If programming a garage door opener
or gate operator, it is advised to unplug
the device during the “cycling” process
to prevent possible overheating.
While the indicator light is flashing in
amber, press the button on the
hand-held transmitter for 2 seconds
and release it repeatedly until the
indicator light changes from amber to
green.
Go back to Step 4 of Programming the
HomeLink System to complete the
procedure.
▼ Operating the HomeLink System
Press the programmed HomeLink
button to operate a programmed
device.
▼
Reprogramming the HomeLink
system
To program a device to HomeLink
using a HomeLink button previously
trained, follow these steps:
1. Press and hold the desired
HomeLink button. DO NOT release
the button.
2. After 20 seconds, the indicator light
fl ashes in amber. After the indicator
light flashes, release the HomeLink
button.
3. Go back to Step 2 of Programming the HomeLink System to complete
the procedure.
NOTE
If the programming has not been
completed, the system returns to the
previous programming.
▼Erasing Programmed HomeLink
Buttons
NOTE
All of the programmed HomeLink
buttons are reset. Individual buttons
cannot be reset, however, individual
buttons can be reprogrammed. For
individual button reprogramming,
refer to Reprogramming the
HomeLink System (page 4-63).
Verify that the programming has
been erased if you resell the vehicle.

WARNING
Do not rely completely on DAA and
always drive carefully:
The DAA detects driver fatigue and
decreased attentiveness and
encourages the driver to take a rest,
however, it is not designed to prevent
the vehicle from straying. If you rely too
much on the DAA it could lead to an
accident. Drive carefully and operate
the steering wheel appropriately.
In addition, the system may not be
able to detect driver fatigue and
decreased attentiveness correctly
depending on the traffic and driving
conditions. The driver must take
su fficient rest in order to drive safely.
NOTE
The DAA operates when all of the
following conditions are met.
The vehicle speed is about 65 to
140 km/h (41 to 86 mph).
The system detects white (yellow)
lane lines.
The system has completed learning
of the driver’s driving data after 60
minutes have passed since the
driver began driving vehicle.
The DAA does not operate under the
following conditions.
The vehicle speed is less than
about 65 km/h (41 mph).
The vehicle speed exceeds about
140 km/h (86 mph).
The vehicle is making a sharp turn.The vehicle is changing lanes.The system cannot detect white
(yellow) lane lines.
The DAA may not operate normally
under the following conditions.
White (yellow) lane lines are less
visible because of dirt or fading/
patchiness.
The vehicle is jolted or swayed
continuously by strong winds or
rough roads.
The vehicle is driven aggressively.When making frequent lane
changes.
The vehicle is making a curve.The DAA detects driver fatigue and
decreased attentiveness based on
the driving data when the vehicle is
driven at about 65 to 140 km/h (41
to 86 mph) for about 20 minutes.
The driving data will be reset under
the following conditions.
The vehicle is stopped for 15
minutes or longer.
The vehicle is driven at less than
about 65 km/h (41 mph) for
about 30 minutes.

Tra n s m i s s i o n )
*
▼Mazda Radar Cruise Control
(MRCC)
The MRCC system is designed to
maintain headway control*1 with a
vehicle ahead according to your
vehicle's speed using a front radar
sensor to detect the distance to the
vehicle ahead and a preset vehicle
speed without you having to use the
accelerator or brake pedals.
*1 Headway Control: Control of the distance between your vehicle and
the vehicle ahead detected by the
MRCC system.
Additionally, if your vehicle starts
closing in on the vehicle ahead such as
if the vehicle ahead brakes suddenly, a
warning sound and a warning
indication in the display are activated
simultaneously to alert you to maintain
a su fficient distance between the
vehicles.
Also refer to the fo llowing before using
the MRCC.
Front radar sensor (page 4-207)
WARNING
Do not rely completely on the MRCC :
The MRCC 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
su fficiently 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 drive carefully and verify the
surrounding conditions and depress
the brake pedal or accelerator pedal
while keeping a safe distance from
vehicles ahead or on-coming vehicles.
Do not use the MRCC system in the
following locations. Using the MRCC
system at the following locations may
result in an unexpected accident:
 General roads other than highways
(Driving under these conditions
using the MRCC system is not
possible.)
 Roads with sharp curves and where
vehicle tra ffic is heavy with
insu fficient space between vehicles,
or roads where frequent and
repetitive acceleration and
deceleration occur (Driving under
these conditions using the MRCC 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.)
