Transaxle Ranges
The shift position indication in the
instrument cluster illuminates.
Refer to Warning/Indicator Lights on
page 4-21.
The selector lever must be in P or N
position to operate the starter.
P (Park)
P locks the transaxle and prevents the
front wheels from rotating.
WA R N I N G
Always set the selector lever to P position
and set the parking brake:
Only setting the selector lever to the P
position without using the parking brake to
hold the vehicle is dangerous. If P fails to
hold, the vehicle could move and cause an
accident.
CAUTION
 Shifting into P, N or R while the vehicle is
moving can damage your transaxle.
 Shifting into a driving gear or reverse
when the engine is running faster than
idle can damage the transaxle.
R (Reverse)
In position R, the vehicle moves only
backward. You must be at a complete stop
before shifting to or from R, except under
rare circumstances as explained in
Rocking the Vehicle (page 3-42).
N (Neutral)
In N, the wheels and transaxle are not
locked. The vehicle will roll freely even

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 MRCC with Stop & Go function system is in use, it does not cancel even if the
selector lever is operated and any intended engine braking does not occur. If deceleration
is required, lower the set speed or depress the brake pedal.
The sound of the automatic brakes operating may be heard, however, it does not indicate
a problem.
The brake lights turn on while the MRCC with Stop & Go function automatic braking is
operating, however, they may not turn on while the vehicle is on a downslope at the set
vehicle speed or traveling at a constant speed and following a vehicle ahead.

NOTE
The distance-between-vehicles differs depending on the vehicle speed, and the slower the
vehicle speed, the shorter the distance.

How to change the set vehicle speed
To accelerate/decelerate using the SET
switch
When you press the SET
switch, the
vehicle accelerates and when you press the

Operating Tips
Operate the climate control system with
the engine running.
To prevent the battery from being
discharged, do not leave the fan control
dial on for a long period of time with the
ignition switched ON when the engine is
not running.
Clear all obstructions such as leaves,
snow and ice from the hood and the air
inlet in the cowl grille to improve the
system efficiency.
Use the climate control system to defog
the windows and dehumidify the air.
The recirculate mode should be used
when driving through tunnels or while
in a traffic jam, or when you would like
to shut off outside air for quick cooling
of the interior.
Use the outside air position for
ventilation or windshield defrosting.
If the vehicle has been parked in direct
sunlight during hot weather, open the
windows to let warm air escape, then
run the climate control system.
Run the air conditioner about 10
minutes at least once a month to keep
internal parts lubricated.
Have the air conditioner checked before
the weather gets hot. Lack of refrigerant
may make the air conditioner less
efficient.
The refrigerant specifications are
indicated on a label attached to the
inside of the engine compartment. If the
wrong type of refrigerant is used, it
could result in a serious malfunction of
the air conditioner. Consult a
professional, government certified
repairer for the inspection or repair
because a special device is required for
the air conditioner maintenance.
For details, consult an Authorized
Mazda Dealer.
