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 switched off, the selector
lever cannot be shifted from P position.
The ignition cannot be switched to OFF
if the selector lever is not in P position.
▼ 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-wr apped 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 Indication/Indicator Lights on
page 4-26, 4-41, 4-54.
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 3-51).
