MAZDA MODEL CX-7 2008 (in English) Repair Manual

Black plate (61,1)
Sit in the center of the seat and wear seat belts properly:Sitting too close to the side air bag modules or placing hands on them and sleeping
up against the door or hanging out the windows is extremely dangerous. The side
and curtain air bags inflate with great force and speed directly expand along the
door on the side the car is hit. Serious injury could occur if someone is sitting too
close to the door or leaning against a window, or if rear seat occupants grab the
sides of the front seatbacks. Give the side and curtain air bags room to work by
sitting in the center of the seat while the vehicle is moving with seat belts worn
properly.
Do not attach objects on or around the area where driver and front passenger air
bags deploy: Attaching an object to the driver and front passenger air bag modules or placing
something in front of them is dangerous. In an accident, an object could interfere
with air bag inflation and injure the occupants.
Do not attach objects on or around the area where a side air bag deploys: Attaching things to the front seat in such a way as to cover the outboard side of the
seat in any way is dangerous. In an accident the object could interfere with the side
air bag, which inflates from the outboard side of the front seats, impeding the added
protection of the side air bag system or redirecting the air bag in a way that is
dangerous. Furthermore, the bag could be cut open releasing the gas.
Do not hang net bags, map pouches or backpacks with side straps on the front
seats. Never use seat covers on the front seats. Always keep the side air bag modules
in your front seats free to deploy in the event of a side collision.
Do not attach objects on or around the area where a curtain air bag deploys: Attaching objects to the areas where the curtain air bag activates such as on the
windshield glass, side door glass, front and rear window pillars and along the roof
edge and assist grips is dangerous. In an accident the object could interfere with the
curtain air bag, which inflates from the front and rear window pillars and along the
roof edge, impeding the added protection of the curtain air bag system or redirecting
the air bag in a way that is dangerous. Furthermore, the bag could be cut open
releasing the gas.
Do not place hangers or any other objects on the assist grips. When hanging clothes,
hang them on the coat hook directly. Always keep the curtain air bag modules free
to deploy in the event of a side collision or roll-over accident.
Do not place luggage or other objects under the front seats: Placing luggage or other objects under the front seats is dangerous. The components
essential to the supplemental restraint system could be damaged, and in the event of
a side collision, the appropriate air bags may not deploy, which could result in death
or serious injury. To prevent damage to the components essential to the
supplemental restraint system, do not place luggage or other objects under the front
seats.

Do not touch the components of the supplemental restraint system after the air bags
have inflated:Touching the components of the supplemental restraint system after the air bags
have inflated is dangerous. Immediately after inflation, they are very hot. You could
get burned.
Never install any front-end equipment to your vehicle: Installation of front-end equipment, such as frontal protection bar (kangaroo bar,
bull bar, push bar, or other similar devices), snowplow, or winches, is dangerous. The
air bag crash sensor system could be affected. This could cause air bags to inflate
unexpectedly, or it could prevent the air bags from inflating during an accident.
Front occupants could be seriously injured.
Do not modify the suspension: Modifying the vehicle suspension is dangerous. If the vehicle's height or the
suspension is modified, the vehicle will be unable to accurately detect a collision or
roll-over accident resulting in incorrect or unexpected air bag deployment and the
possibility of serious injuries.
Do not use tires or wheels other than those specified for your Mazda: Use of any tire or wheel other than those specified for your Mazda (page 10-6) is
dangerous. Use of such wheels will prevent the vehicle's accident detections system
from accurately detecting a collision or roll-over accident resulting in incorrect or
unexpected air bag deployment and the possibility of serious injuries.
Do not overload your vehicle: Overloading your vehicle is dangerous as is could prevent the air bag crash sensor
system from accurately detecting a collision or roll-over accident resulting in
incorrect or unexpected air bag deployment and the possibility of serious injuries.
The gross axle weight rating (GAWR) and the gross vehicle weight rating (GVWR) for
your vehicle are on the Motor Vehicle Safety Standard Label on the driver's door
frame. Do not exceed these ratings.
Do not drive the vehicle off-road: Driving your Mazda off-road is dangerous because the vehicle has not been designed
to do such. Driving the vehicle off-road could prevent the air bag crash sensor system
from accurately detecting a collision or roll-over accident resulting in incorrect or
unexpected air bag deployment and the possibility of serious injuries.

Do not modify the supplemental restraint system:Modifying the components or wiring of the supplemental restraint system is
dangerous. You could accidentally activate it or make it inoperable. Do not make
any modifications to the supplemental restraint system. This includes installing trim,
badges, or anything else over the air bag modules. It also includes installing extra
electrical equipment on or near system components or wiring. An Authorized Mazda
Dealer can provide the special care needed in the removal and installation of front
seats. It is important to protect the air bag wiring and connections to assure that the
bags do not accidentally deploy, the driver seat slide position sensor and front
passenger seat weight sensors are not damaged and that the seats retain an
undamaged air bag connection.
NOTE
lWhen an air bag deploys, a loud inflation noise can be heard and some smoke will be released.
Neither is likely to cause injury, however, the texture of the air bags may cause light skin injuries
on body parts not covered with clothing through friction.
lShould you sell your Mazda, we urge you to tell the new owner of its air bag systems and that
familiarization with all instructions about them, from the Owner's Manual, is important.

How the SRS Air Bags Work
Your Mazda is equipped with the following types of SRS air bags. SRS air bags are
designed to work together with the seat belts to help to reduce injuries during an accident.
The SRS air bags are designed to provide further protection for passengers in addition to
the seat belt functions. Be sure to wear seat belts properly.
qFront Seat Belt Pretensioners
The front seat belt pretensioners are designed to deploy in moderate or severe frontal, near
frontal collisions or roll-over accidents.
qDriver Air Bag
The driver air bag is mounted in the steering wheels.
When air bag crash sensors detect a frontal impact of greater than moderate force, the
driver's air bag inflates quickly helping to reduce injury mainly to the driver's head or chest
caused by directly hitting the steering wheel.
The driver, dual stage air bag controls air bag inflation in two energy stages. During an
impact of moderate severity the driver air bag deploys with lesser energy, whereas during
more severe impacts, it deploys with more energy.

qFront Passenger Air Bag
The front passenger air bag is mounted in the front passenger dashboard.
The inflation mechanism for the front passenger air bag is the same as the driver's air bag,
as mentioned above. In addition, the front passenger air bag is designed to only deploy in
accordance with the total seated weight on the front passenger seat. For details, refer to the
driver and front passenger occupant classification system (page 2-60).
qSide Air Bags
The side bags are mounted in the outboard sides of the front seatbacks.
When the air bag crash sensors detect a side impact of greater than moderate force, the
system inflates the side air bag only on the side in which the vehicle was hit. The side air
bag inflates quickly to reduce injury to the driver or front passenger's chest caused by
directly hitting interior parts such as a door or window. In addition, the front passenger side
air bag is designed to only deploy in accordance with the total seated weight on the front
passenger seat. For details, refer to the driver and front passenger occupant classification
system (page 2-60).

qCurtain Air Bags
The curtain air bags are mounted in the front and rear window pillars, and the roof edge
along both sides.
When the air bag crash sensors detect a side impact of greater than moderate force, the
curtain air bag inflates quickly and helps to reduce injury mainly to the rear outboard
passenger's head caused by directly hitting interior parts such as a door or window.
In a side impact:
Greater than moderate impact to one side of the vehicle will cause the curtain air bag on
that side only to inflate.
The only one side of curtain air bag will deploy
only on the side the vehicle receives the force of
the impact.
In a roll-over:
In response to a vehicle roll-over, both the curtain air bags inflate.
Both curtain air bags will deploy after
the roll-over accident is detected.

qAir Bag/Front Seat Belt Pretensioner System Warning Light
If the air bag/front seat belt pretensioner system is working properly, the warning light
illuminates when the ignition switch is turned to the ON position or after the engine is
cranked. The warning light turns off after a specified period of time.
A system malfunction is indicated if the warning light constantly flashes, constantly
illuminates or does not illuminate at all when the ignition switch is turned to the ON
position. If any of these occur, consult an Authorized Mazda Dealer as soon as possible.
The system may not work in an accident.
WARNING
Never tamper with the air bag/pretensioner systems and always have an Authorized
Mazda Dealer perform all servicing and repairs:
Self-servicing or tampering with the systems is dangerous. An air bag/pretensioner
could accidentally activate or become disabled causing serious injury or death.
qAir Bag/Front Seat Belt Pretensioner System Warning Beep
If a malfunction is detected in both the air bag/front seat belt pretensioner system and the
warning light, a warning beep sound will be heard for about 1 minute. After that, the one-
minute beep will be repeated every 30 minutes.
Have your vehicle inspected at an Authorized Mazda Dealer as soon as possible.
WARNING
Do not drive the vehicle with the air bag/front seat belt pretensioner system warning
beep sounding:
Driving the vehicle with the air bag/front seat belt pretensioner system warning beep
sounding is dangerous. In a collision, the air bags and the front seat belt
pretensioner system will not deploy and this could result in death or serious injury.
Contact an Authorized Mazda Dealer to have the vehicle inspected as soon as
possible.
