WARNING: Never place a rear facing infant seat in the front
seat unless the passenger air bag is turned off.
Steps you can take to properly position yourself away from the airbag:
• Move your seat to the rear as far as you can while still reaching the
pedals comfortably.
• Recline the seat slightly (one or two degrees) from the upright
position.
WARNING: Do not put anything on or over the air bag module
including hands or feet. Placing objects on or over the air bag
inflation area may cause those objects to be propelled by the
air bag into your face and torso causing serious injury.
WARNING: Do not attempt to service, repair, or modify the Air
Bag Supplemental Restraint System or its fuses. See your
authorized Mazda dealership.
WARNING: Modifications to the front end of the vehicle,
including frame, bumper, front end body structure, tow hooks
and snow plows may effect the performance of the air bag
sensors increasing the risk of injury. Do not modify the front
end of the vehicle.
WARNING: Additional equipment may effect the performance
of the air bag sensors increasing the risk of injury. Consult your
authorized Mazda dealership before installation of additional
equipment.
WARNING: The front passenger air bag is not designed to offer
protection to an occupant in the center front seating position.

AUTOMATIC TRANSMISSION OPERATION (IF EQUIPPED)
Brake-shift interlock
This vehicle is equipped with a brake-shift interlock feature that prevents
the gearshift lever from being moved from P (Park) when the ignition is
in the ON position unless the brake pedal is depressed.
If you cannot move the gearshift lever out of P (Park) with ignition in
the ON position and the brake pedal depressed:1. Apply the parking brake, turn ignition key to LOCK, then
remove the key.
2. Insert the key and turn it to OFF. Apply the brake pedal
and shift to N (Neutral).
WARNING: When the key is in the ignition OFF position, the
automatic transmission shift lever can be moved from the P
(Park) position without the brake pedal depressed. To avoid
unwanted vehicle movement, always set the parking brake. 3. Start the vehicle.
If it is necessary to use the above procedure to move the gearshift lever,
it is possible that a fuse has blown or the vehicle’s brakelamps are not
operating properly. Refer to Fuses and relaysin theRoadside
emergencies chapter.
WARNING: Do not drive your vehicle until you verify that the
brakelamps are working.
WARNING: Always set the parking brake fully and make sure
the gearshift is latched in P (Park). Turn the ignition to the
LOCK position and remove the key whenever you leave your
vehicle.

FUSES AND RELAYS
Fuses
If electrical components in the
vehicle are not working, a fuse may
have blown. Blown fuses are
identified by a broken wire within
the fuse. Check the appropriate
fuses before replacing any electrical
components.
Note: Always replace a fuse with one that has the specified amperage
rating. Using a fuse with a higher amperage rating can cause severe wire
damage and could start a fire.
