2003 MAZDA MODEL B-SERIES air condition

WARNING: Several air bag system components get hot after
inflation. Do not touch them after inflation or you may be
burned.
WARNING: If the air bag has deployed, the air bag will not
function again and must be replaced immediately. If the air bag
is not replaced, the unrepaired area will increase the risk of
injury in a collision.
The SRS consists of:
²driver and passenger air bag modules (which include the inflators and
air bags),
²passenger air bag deactivation switch and restraint control module
(RCM)
²a readiness light and tone,
²and the electrical wiring which connects the components.
The RCM (restraints control module) monitors its own internal circuits
and the supplemental air bag electrical system warning (including the
passenger air bag deactivation switch, the system wiring, the air bag
system readiness light, the air bag back up power and the air bag
ignitors).
Determining if the system is operational
The SRS uses readiness lights in the instrument cluster and the
passenger air bag deactivate switch or a tone to indicate the condition of
the system. Refer to theAir bag readinesssection in the
Instrumentationchapter orPassenger air bag deactivate switch
section in this chapter. Routine maintenance of the air bag is not
required.
A difficulty with the system is indicated by one or more of the following:
²The readiness lights will either
flash or stay lit.
²The readiness lights will not
illuminate immediately after
ignition is turned on.
²A series of five beeps will be heard. The tone pattern will repeat
periodically until the problem and/or light are repaired.
Seating and Safety Restraints

²the infant has a medical condition which, according to the infant's
physician, makes it necessary for the infant to ride in the front so that
the driver can constantly monitor the child's condition.
2.Child age 1 to 12.A child age 1 to 12 must ride in the front seat
because:
²the vehicle has no rear seat;
²although children ages 1 to 12 ride in the rear seat(s) whenever
possible, children ages 1 to 12 sometimes must ride in the front
because no space is available in the rear seat(s) of the vehicle; or
²the child has a medical condition which, according to the child's
physician, makes it necessary for the child to ride in the front seat so
that the driver can constantly monitor the child's condition.
3.Medical condition.A passenger has a medical condition which,
according to his or her physician:
²causes the passenger air bag to pose a special risk for the passenger;
and
²makes the potential harm from the passenger air bag in a crash
greater than the potential harm from turning OFF the air bag and
allowing the passenger, even if belted, to hit the dashboard or
windshield in a crash.
WARNING: This vehicle has special energy management safety
belts for the driver and right front passenger. These particular
belts are specifically designed to work with air bags to help
reduce the risk of injury in a collision. The energy management
safety belt is designed to give or release additional belt
webbing in some accidents to reduce concentration of force on
an occupant's chest and reduce the risk of certain bone
fractures and injuries to underlying organs. In a crash, if the air
bag is turned OFF, this energy management safety belt might
permit the person wearing the belt to move forward enough to
incur a serious or fatal injury. The more severe the crash, and
the heavier the occupant, the greater the risk is. Be sure the air
bag is turned ON for any person who does not qualify under the
NHTSA deactivation criteria.

WARNING: If you smell exhaust fumes inside your vehicle,
have your dealer inspect your vehicle immediately. Do not drive
if you smell exhaust fumes.
Important ventilating information
If the engine is idling while the vehicle is stopped for a long period of
time, open the windows at least 2.5 cm (one inch) or adjust the heating
or air conditioning to bring in fresh air.
BRAKES
Occasional brake noise is normal. If a metal-to-metal, continuous grinding
or continuous squeal sound is present, the brake linings may be worn-out
and should be inspected by a qualified service technician. If the vehicle
has continuous vibration or shudder in the steering wheel while braking,
the vehicle should be inspected by a qualified service technician.
Four-wheel anti-lock brake system (ABS)
This vehicle is equipped with an anti-lock braking system (ABS), a noise
from the hydraulic pump motor and pulsation in the pedal may be
observed during ABS braking events. Pedal pulsation coupled with noise
while braking under panic conditions or on loose gravel, bumps, wet or
snowy roads is normal and indicates proper functioning of the vehicle's
anti-lock brake system.
NOTE:The ABS performs a self-check after you start the engine and
begin to drive away.
A brief mechanical noise may be heard during this test. This is normal. If
a malfunction is found, the ABS warning light will come on. If the vehicle
has continuous vibration or shudder in the steering wheel while braking,
the vehicle should be inspected by an authorized Mazda dealership.
The ABS operates by detecting the
onset of wheel lockup during brake
applications and compensates for
this tendency. The wheels are
prevented from locking even when
the brakes are firmly applied. The
accompanying illustration depicts
the advantage of an ABS equipped
vehicle (on bottom) to a non-ABS
equipped vehicle (on top) during hard braking with loss of front braking
traction.

WARNING: Do not spin the wheels at over 56 km/h (35 mph).
The tires may fail and injure a passenger or bystander.
Sand
When driving over sand, try to keep all four wheels on the most solid
area of the trail. Do not reduce the tire pressures but shift to a lower
gear and drive steadily through the terrain. Apply the accelerator slowly
and avoid spinning the wheels.
Mud and water
If you must drive through high water, drive slowly. Traction or brake
capability may be limited.
When driving through water, determine the depth; avoid water higher
than the bottom of the hubs (if possible) and proceed slowly. If the
ignition system gets wet, the vehicle may stall.
Once through water, always try the brakes. Wet brakes do not stop the
vehicle as effectively as dry brakes. Drying can be improved by moving
your vehicle slowly while applying light pressure on the brake pedal.
After driving through mud, clean off residue stuck to the driveshafts and
tires. Excess mud stuck on tires and rotating driveshafts causes an
imbalance that could damage drive components.
If the transmission, transfer case or front axle are submerged in water,
their fluids should be checked and changed, if necessary.
Driving through deep water where the transmission vent tube is
submerged may allow water into the transmission and cause
internal transmission damage.
Replace rear axle lubricant any time the axle has been submerged in
water. The rear axle does not normally require a lubricant change for the
life of the vehicle. Rear axle lubricant quantities are not to be checked or
changed unless a leak is suspected or repair is required.
Driving on hilly or sloping terrain
When driving on a hill, avoid driving crosswise or turning on steep
slopes. You could lose traction and slip sideways. Drive straight up,
straight down or avoid the hill completely. Know the conditions on the
other side of a hill before driving over the crest.
When climbing a steep hill, start in a lower gear rather than downshifting
to a lower gear from a higher gear once the ascent has started. This
reduces strain on the engine and the possibility of stalling.

OVERHEATING
If the temperature gauge indicates overheating and you experience
power loss, you hear a loud knocking or pinging noise, the engine is
probably too hot.
If this happens:
1. Drive safely to the side of the road and park off the right-of-way.
2. Shift the automatic transmission into P (Park) or the manual
transmission into the neutral position, and apply the parking brake.
3. Turn off the air conditioner.
WARNING: Steam from an overheated engine is dangerous. The
escaping steam could seriously burn you. Open the hood ONLY
after steam is no longer escaping from the engine.
4. Check whether coolant or steam is escaping from under the hood or
from the engine compartment.
²If steam is coming from the engine compartment:do not go near
the front of the vehicle. Stop the engine, then turn the ignition switch

INTRODUCTION
Be extremely careful to prevent injury to yourself and others and
damage to your vehicle when using this manual for inspection and
maintenance.
If you're unsure about any procedure it describes, we strongly urge you
to have a reliable and qualified service shop perform the work, preferably
an Authorized Mazda Dealer.
Factory-trained Mazda technicians and genuine Mazda parts are best for
your vehicle. Without this expertise and the parts that have been
designed and made especially for your Mazda, inadequate, incomplete,
and insufficient servicing may result in problems. This could lead to
vehicle damage or an accident and injuries.
For expert advice and quality service, consult an Authorized Mazda
Dealer.
The owner should retain evidence that proper maintenance has been
performed as prescribed.
A claim against a warranty will not qualify if it results from lack of
maintenance and not from defective material or authorized Mazda
workmanship.
Any auto repair shop using parts equivalent to your Mazda's original
equipment may perform maintenance.But we recommend that it
always be done by an Authorized Mazda Dealer using genuine
Mazda parts.
