Shift-Lock System
The shift-lock system prevents shifting out
of P unless the brake pedal is depressed.

To shift from P:
1. Depress and hold the brake pedal.
2. Start the engine.
3. Press and hold the lock-release button.
4. Move the selector lever.
NOTE
•When the ignition is switched to ACC or
the ignition is switch ed off, the selector
lever cannot be shifted from P.
•The ignition cannot be switched to OFF
if the selector lever is not in P.
▼ Shift-Lock Override
If the selector lever will not move from P
using the proper shift procedure, continue
to hold down the brake pedal.
1. Remove the shift-lock override cover
using a cloth-wrapped flat head
screwdriver.
2. Insert a screwdriver and push it down.
Cover
3. Press and hold the lock-release button.
4. Move the selector lever.
Take the vehicle to an Authorized Mazda
Dealer to have the system checked.
Transaxle Ranges
•The shift position indication in the
instrument cluster illuminates. Refer to
Warning/Indicator Lights on page 4-31.
•The selector lever must be in P or N 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 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.

•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.

Operating Tips
•Operate the climate control system with
the engine running.
•To prevent the battery from being
discharged, do not leave the fan control
switch 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 cond itioner 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 ser ious 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 conditi oner maintenance.
For details, consult an Authorized
Mazda Dealer.
