child-restraint system:
Not following the child-restraint system manufacturer's instructions when installing the
child-restraint system is dangerous. If seat belts or a foreign object prevent the child-restraint
system from being securely attached to the ISOFIX/LATCH
*1 lower anchors and the
child-restraint system is installed improperly, the child-restraint system could move in a
sudden stop or collision causing serious injury or death to the child or other occupants. When
installing the child-restraint system, make sure there are no seat belts or foreign objects near
or around the ISOFIX/LATCH
*1 lower anchors. Always follow the child-restraint system
manufacturer's instructions.

manufacturer's instructions when
installing tethers.
*1 ISOFIX (Mexico)/LATCH (ExceptMexico)
WA R N I N G
Use the tether and tether anchor only for a
child-restraint system:
Using the tether or tether anchor to secure
anything but a child-restraint system is
dangerous. This could weaken or damage
the tether or tether anchor and result in
injury.
Always remove the head restraint and
install child-restraint system (except when
installing a backless booster seat):
Installing a child-restraint system without
removing the head restraint is dangerous.
The child-restraint system cannot be
installed correctly which may result in
death or injury to the child in a collision.
Tether strap
Forward
Second-row
center seat
Always attach the tether strap to the
correct tether anchor position:
Attaching the tether strap to the incorrect
tether anchor position is dangerous. In a
collision, the tether strap could come off
and loosen the child-restraint system. If the
child-restraint system moves it could result
in death or injury to the child.
Always install the head restraint and adjust
it to the appropriate position after
removing the child-restraint system:
Driving with the head restraint removed is
dangerous as impact to the occupant's
head cannot be prevented during
emergency braking or in a collision, which

Seat belts must be worn in air bag equipped vehicles:
Depending only on the air bags for protection during an accident is dangerous. Alone, air
bags may not prevent serious injuries. The appropriate air bags can be expected to
inflate
only in the first accident, such as frontal, near frontal or side collision s or roll-over accidents
that are at least moderate. Vehicle occu pants should always wear seat belts.

Children should not ride in the front passenger seat:
Placing a child, 12 years or under, in the front seat is dangerous. The child could be hit by a
deploying air bag and be seriously injured or even killed. A sleeping child is more likely to lean
against the door and be hit by the side air ba g in moderate collision to the front-passenger
side of the vehicle. Whenever possible, always secure a child 12 years and under on the rear
seats with an appropriate child-restrain t system for the child's age and size.
Never use a rear-facing child-restraint system in the front seat with an air bag that could
deploy:
Rear-facing child-restraint systems on the front seat are particularly dangerous even though
you may feel assured that a front passenger air ba g will not deploy based on the fact that the
front passenger air bag deactivation indicator light illuminates. The child-restraint system
can be hit by a deploying air bag and moved viol ently backward resulting in serious injury or
death to the child.
Do not sit too close to the driver and front passenger air bags:
Sitting too close to the driver and front passenger air bag modules or placing hands or feet on
them is extremely dangerous. The driver and fron t passenger air bags inflate with great force
and speed. Serious injuries could occur if some one is too close. The driver should always hold
onto only the rim of the steering wheel. The front seat passenger should keep both feet on the
floor. Front seat occupants should adjust their seats as far back as possible and always sit
upright against the seatbacks wi th seat belts worn properly.

Luggage or other items are placed between the front passenger seat and driver seat.
 An electric device is put on the front passenger's seat.
 An additional electrical device, such as a seat warmer is installed to the surface of the front
passenger seat.
The front passenger front and side air bags an d seat belt pretensioner systems will deactivate
if the front passenger air bag deactivation indicator light turns on.
CAUTION
 To assure proper deployment of the front air bag and to prevent damage to the sensor in
the front seat cushion:
 Do not place sharp objects on the front seat cushion or leave heavy luggage on them.
 Do not spill any liquids on the fr ont seats or under the front seats.
 To allow the sensors to function pr operly, always perform the following:
 Adjust the front seats as far back as possibl e and always sit upright against the seatbacks
with seat belts worn properly.
 If you place your child on the front passe nger seat, secure the child-restraint system
properly and slide the front passenger seat as far back as possible (page 2-53).
NOTE
The system requires about 10 seconds to alternate between turning the front passenger
front and side air bags and seat belt pretensioner system on or off.
The front passenger air bag deactivation indicator light may turn on repeatedly if luggage
or other items are put on the front passenger se at, or if the temperature of the vehicle's
interior changes suddenly.
The front passenger air bag deactivation indicator light may turn on for 10 seconds if the
electrostatic capacity on the front passenger seat changes.
The air bag/front seat belt pr etensioner system warning light might turn on if the front
passenger seat receives a severe impact.
If the front passenger air bag deactivation indicator light does not turn on after installing
a child-restraint system on the front passenger seat, first, re-install your child-restraint
system according to the procedure in this owner's manual. Then, if the front passenger air
bag deactivation indicator light still does not turn on, install the child-restraint system on
the rear seat and consult an Authorized Mazda Dealer as soon as possible.

WA R N I N G
Always take all children and pets with you
or leave a responsible person with them:
Leaving a child or a pet unattended in a
parked vehicle is dangerous. In hot
weather, temperatures inside a vehicle can
become high enough to cause brain
damage or even death.
Do not leave the key in your vehicle with
children and keep them in a place where
your children will not find or play with
them:
Leaving children in a vehicle with the key is
dangerous. This could result in someone
being badly injured or even killed.
Keep all doors locked when driving:
Unlocked doors in a moving vehicle are
dangerous. Passengers can fall out if a
door is accidentally opened and can more
easily be thrown out in an accident.
Always close all the windows and
moonroof, lock the doors and the liftgate
and take the key with you when leaving
your vehicle unattended:
Leaving your vehicle unlocked is dangerous
as children could lock themselves in a hot
vehicle, which could result in death. Also, a
vehicle left unlocked becomes an easy
target for thieves and intruders.
After closing the doors and the liftgate,
always verify that they are securely closed:
Doors and the liftgate not securely closed
are dangerous, if the vehicle is driven with
a door and the liftgate not securely closed,
the door and the liftgate could open
unexpectedly resulting in an accident.
Always confirm the safety around the
vehicle before opening a door and the
liftgate:
Suddenly opening a door and the liftgate is
dangerous. A passing vehicle or a
pedestrian could be hit and cause an
accident.
CAUTION
Always confirm the conditions around
the vehicle before opening/closing the
doors and the liftgate and use caution
during strong winds or when parked on
an incline. Not being aware of the
conditions around the vehicle is
dangerous because fingers could get
caught in the door and the liftgate or a
passing pedestrian could be hit, resulting
in an unexpected accident or injury.
NOTE
Always stop the engine and lock the
doors. In addition, to prevent theft of
valuables, do not leave them inside the
cabin.
If the key is left in the following areas
and you leave the vehicle, the doors may
be locked depending on the radio wave
conditions even if the key is left in the
vehicle.

Never allow a person to ride in the luggage
compartment:
Allowing a person to ride in the luggage
compartment is dangerous. The person in
the luggage compartment could be
seriously injured or
killed during sudden
braking or a collision.
Do not drive with the liftgate open:
Exhaust gas in the cabin of a vehicle is
dangerous. An open liftgate in a moving
vehicle will cause exhaust gas to be drawn
into the cabin. This gas contains CO
(carbon monoxide), which is colorless,
odorless, and highly poisonous, and it can
cause loss of consciousness and death.
Moreover, an open liftgate could cause
occupants to fall out in an accident.
Do not stack or leave loaded luggage
unsecured in the luggage compartment:
Otherwise, the luggage may move or
collapse, resulting in injury or an accident.
In addition, do not load luggage higher
than the seatbacks. It may affect the side or
rear field of view.
CAUTION
 Before opening the liftgate, remove any
snow and ice accumulation on it.
Otherwise, the liftgate could close under
the weight of the snow and ice resulting
in injury.
