2009 MAZDA MODEL B4000 CAB PLUS 4 TRUCK brakes

GVWR (Gross Vehicle Weight
Rating)– is the maximum
allowable weight of the fully loaded
vehicle (including all options,
equipment, passengers and cargo).
The GVWR is shown on the
Safety Compliance Certification
Label located on the B-Pillar or
the edge of the driver’s door.
The GVW must never exceed the
GVWR.
WARNING: Exceeding the Safety Compliance Certification Label
vehicle weight rating limits could result in substandard vehicle
handling or performance, engine, transmission and/or structural
damage, serious damage to the vehicle, loss of control and personal
injury.
GCW (Gross Combined Weight) – is the weight of the loaded vehicle
(GVW) plus the weight of the fully loaded trailer.
GCWR (Gross Combined Weight Rating) – is the maximum allowable
weight of the vehicle and the loaded trailer – including all cargo and
passengers – that the vehicle can handle without risking damage.
(Important: The towing vehicle’s braking system is rated for operation at
GVWR, not at GCWR.) Separate functional brakes should be used for
safe control of towed vehicles and for trailers where the GCW of the
towing vehicle plus the trailer exceed the GVWR of the towing vehicle.
The GCW must never exceed the GCWR.

Special loading instructions for owners of pickup trucks and
utility-type vehicles
WARNING:For important information regarding safe operation
of this type of vehicle, see the Preparing to drive your
vehicle section in the Drivingchapter of this Owner’s Manual.
WARNING:Loaded vehicles may handle differently than
unloaded vehicles. Extra precautions, such as slower speeds and
increased stopping distance, should be taken when driving a heavily
loaded vehicle.
Your vehicle can haul more cargo and people than most passenger cars.
Depending upon the type and placement of the load, hauling cargo and
people may raise the center of gravity of the vehicle.
TRAILER TOWING
Your vehicle may tow a class I, II or III trailer provided the maximum
trailer weight is less than or equal to the maximum trailer weight listed
for your engine and rear axle ratio on the following charts.
Your vehicle’s load capacity is designated by weight, not by volume, so
you cannot necessarily use all available space when loading a vehicle.
Towing a trailer places an additional load on your vehicle’s engine,
transmission, axle, brakes, tires and suspension. Inspect these
components carefully after any towing operation.

underbody structure. Use a frame-mounted weight distributing hitch for
trailers over 2,000 lb. (907 kg).
Do not install a single or multi-clamp type bumper hitch, or a hitch
which attaches to the axle. Underbody mounted hitches are acceptable if
they are installed properly. Follow the towing instructions of a reputable
rental agency.
Whenever a trailer hitch and hardware are removed, make sure all
mounting holes in the underbody are properly sealed to prevent noxious
gases or water from entering.
Safety chains
Always connect the trailer’s safety chains to the frame or hook retainers
of the vehicle hitch. To connect the trailer’s safety chains, cross the
chains under the trailer tongue and allow slack for turning corners.
If you use a rental trailer, follow the instructions that the rental agency
gives to you.
Do not attach safety chains to the bumper.
Trailer brakes
Electric brakes and manual, automatic or surge-type trailer brakes are
safe if installed properly and adjusted to the manufacturer’s
specifications. The trailer brakes must meet local and Federal
regulations.
WARNING:Do not connect a trailer’s hydraulic brake system
directly to your vehicle’s brake system. Your vehicle may not
have enough braking power and your chances of having a collision
greatly increase.
The braking system of the tow vehicle is rated for operation at the
GVWR not GCWR.
Trailer lamps
Trailer lamps are required on most towed vehicles. Make sure all running
lights, brake lights, turn signals and hazard lights are working. Contact
your authorized dealer or trailer rental agency for proper instructions
and equipment for hooking up trailer lamps.
Using a step bumper
The optional step bumper is equipped with an integral hitch and requires
only a ball with a 3/4 inch (19 mm) shank diameter. The bumper has a
2,000 lb (907 kg) trailer weight and 200 lb (91 kg) tongue weight
capability.

has continuous vibration or shudder in the steering wheel while braking,
the vehicle should be inspected by an authorized dealer.
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:The Anti-Lock system does not decrease the time
necessary to apply the brakes or always reduce stopping
distance. Always leave enough room between your vehicle and the
vehicle in front of you to stop.
Using ABS
When hard braking is required, apply continuous force on the brake
pedal; do not pump the brake pedal since this will reduce the
effectiveness of the ABS and will increase your vehicle’s stopping
distance. The ABS will be activated immediately, allowing you to retain
steering control during hard braking and on slippery surfaces. However,
the ABS does not decrease stopping distance.
ABS warning lamp
The ABS lamp in the instrument
cluster momentarily illuminates
when the ignition is turned on. If
the light does not illuminate during
start up, remains on or flashes, the
ABS may be disabled and may need to be serviced.
Even when the ABS is disabled,
normal braking is still effective. If
your BRAKE warning lamp
illuminates with the parking brake
released, have your brake system
serviced immediately by an authorized dealer.

Parking brake
Apply the parking brake whenever
the vehicle is parked. To set the
parking brake, press the parking
brake pedal down until the pedal
stops.
The BRAKE warning lamp in the
instrument cluster illuminates and
remains illuminated (when the
ignition is turned on) until the
parking brake is released.
WARNING:Always set the parking brake fully and make sure
that the gearshift is securely latched in P (Park) (automatic
transmission) or in 1 (First) (manual transmission).
Note: The parking brake is not recommended to stop a moving vehicle.
However, if the normal brakes fail, the parking brake can be used to stop
your vehicle in an emergency. Since the parking brake applies only the
rear brakes, the vehicle’s stopping distance will increase greatly and the
handling of your vehicle will be adversely affected.
Pull the release lever to release the
brake.
Driving with the parking brake
on will cause the brakes to wear
out quickly and reduce fuel
economy.

In an emergency, to disable the malfunctioning brake-shift interlock
feature in order to shift the vehicle from P(Park) follow these steps:
WARNING:To prevent vehicle movement when following this
procedure, park on a level surface, ensure parking brake is set,
and block the rear wheels.
1. Apply the parking brake. Turn key to the 2 (lock) and then remove the key;
2. Disconnect the negative (Black) battery cable from the battery;
3. Insert the key and turn to 3 (off). Shift to N (Neutral);
4. Reconnect the negative (Black) battery cable to the battery;
5. Start the vehicle.
See your authorized dealer for service immediately.
WARNING: If your brake lamps are not working properly or if
you have disconnected the vehicle battery cables, the vehicle
brake lamps and hazard flashers may not properly warn traffic of a
vehicle breakdown or approaching danger, which can increase the risk
of serious injury or death. To minimize the risk of serious injury or
death, be aware of your surroundings, use other hazard signaling
devices if available, and move the vehicle to a safe location away from
traffic as soon as possible.
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.
WARNING: If the parking brake is fully released, but the brake
warning lamp remains illuminated, the brakes may not be
working properly. See your authorized dealer.

BRAKE FLUID
The fluid level will drop slowly as
the brakes wear, and will rise when
the brake components are replaced.
Fluid levels between the “MIN” and
“MAX” lines are within the normal
operating range; there is no need to
add fluid. If the fluid levels are
outside of the normal operating
range the performance of the
system could be compromised; seek
service from your authorized dealer
immediately.
CLUTCH FLUID (IF EQUIPPED)
Check the fluid level. Refer toscheduled maintenancefor the service
interval schedules.
During normal operation, the fluid level in the clutch reservoir should
remain constant. If the fluid level drops, refill the fluid level to the step
in the reservoir.
Use only a DOT 3 brake fluid designed to meet Mazda specification.
Refer to Maintenance product specifications and capacities in this
chapter.
WARNING: Carefully read cautionary information on product

Fluid levels below the MAX line that do not trigger the brake warning light are within the normal
operating range, there is no need to add fluid. If the levels are outside the normal operating range,
the performance of your brake system could be compromised, seek service from your authorized
dealer immediately.2Add the coolant type originally equipped in your vehicle. Do not mix different colors or types of
coolant. Do not use Mazda Extended Life Engine Coolant (orange in color). Refer to Adding
engine coolant, in this chapter.3Service refill capacity is determined by filling the transmission to the bottom of the filler hole with
the vehicle on a level surface.4Automatic transmissions that require MERCON V should only use MERCONV fluid or fluid that
is specified dual usage MERCON/MERCON V. Refer toscheduled maintenance to determine
the correct service interval. Use of any fluid other than the recommended fluid may cause
transmission damage.5Indicates only approximate dry-fill capacity. Some applications may vary based on cooler size and
if equipped with an in-tank cooler. The amount of transmission fluid and fluid level should be set
by the indication on the dipstick’s normal operating range.6Traction-Lok axles use 4.75–5.0 pints (2.2–2.4L) of rear axle lubricant. Add 4 oz. (118 ml) of
Additive Friction Modifier meeting Mazda specifications for complete refill of Traction-Lok axles.
Service refill capacities are determined by filling the rear axle 1/4 inch to 9/16 inch (6 mm to
14 mm) below the bottom of the filler hole.
If submerged in water, the rear axle lubricant should be changed.
