2004 MAZDA MODEL B4000 4WD TRUCK engine

Shifting to/from 4X4 LOW
1. Bring the vehicle to a complete stop
2. Depress the brake
3. On vehicles equipped with an automatic transmission, place the
transmission in N (Neutral); on vehicles equipped with a manual
transmission, depress the clutch.
4. Move the 4WD control to the desired position.
²If shifting into 4X4 LOW, wait for the 4WD LOW light in the
instrument cluster to turnonindicating the shift is complete.
²If shifting out of 4X4 LOW, wait for the 4WD LOW light in the
instrument cluster to turnoffindicating the shift is complete.
Driving off-road with 4WD
Your vehicle is specially equipped for driving on sand, snow, mud and
rough terrain and has operating characteristics that are somewhat
different from conventional vehicles, both on and off the road.
Maintain steering wheel control at all times, especially in rough terrain.
Since sudden changes in terrain can result in abrupt steering wheel
motion, make sure you grip the steering wheel from the outside. Do not
grip the spokes.
Drive cautiously to avoid vehicle damage from concealed objects such as
rocks and stumps.
You should either know the terrain or examine maps of the area before
driving. Map out your route before driving in the area. For more
information on driving off-road, read the ªFour Wheelingº supplement in
your owner's portfolio.
If your vehicle gets stuck
If the vehicle is stuck it may be rocked out by shifting from forward and
reverse gears, stopping between shifts, in a steady pattern. Press lightly
on the accelerator in each gear.
Do not rock the vehicle if the engine is not at normal operating
temperature or damage to the transmission may occur.
Do not rock the vehicle for more than a few minutes or damage
to the transmission and tires may occur or the engine may
overheat.

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.
Driving
122

When descending a steep hill, avoid sudden braking. Shift to a lower gear
when added engine braking is desired.
When speed control is on and you are driving uphill, your vehicle speed
may drop considerably, especially if you are carrying a heavy load.
If vehicle speed drops more than 16 km/h (10 mph), the speed control
will cancel automatically. Resume speed with accelerator pedal.
If speed control cancels after climbing the hill, reset speed by pressing
and holding the SET ACCEL button (to resume speeds over 50 km/h [30
mph]).
Automatic transmissions may shift frequently while driving up steep
grades. Eliminate frequent shifting by shifting out of
(Overdrive) into
a lower gear.
Driving on snow and ice
A 4WD vehicle has advantages over 2WD vehicles in snow and ice but
can skid like any other vehicle.
Avoid sudden applications of power and quick changes of direction on
snow and ice. Apply the accelerator slowly and steadily when starting
from a full stop.
When braking, apply the brakes as you normally would. In order to allow
the anti-lock brake system (ABS) to operate properly, keep steady
pressure on the brake pedal.
Make sure you allow sufficient distance between you and other vehicles
for stopping. Drive slower than usual and consider using one of the lower
gears.
DRIVING THROUGH WATER
If driving through deep or standing water is unavoidable, proceed very
slowly especially if the depth is not known. Never drive through water
that is higher than the bottom of the hubs (for trucks) or the bottom of
the wheel rims (for cars). Traction or brake capability may be limited
and your vehicle may stall. Water may also enter your engine's air intake
and severely damage your engine.
Once through the water, always dry the brakes by moving your vehicle
slowly while applying light pressure on the brake pedal. Wet brakes do
not stop the vehicle as quickly as dry brakes.Driving through deep
water where the transmission vent tube or transfer case vent
tube (4x4 vehicles only) are submerged may allow water into the
transmission or transfer case and cause internal
transmission/transfer case damage.

GAW (Gross Axle Weight)± is the total weight placed on each axle
(front and rear) ± including vehicle curb weight and all payload.
GAWR (Gross Axle Weight Rating)± is the maximum allowable
weight that can be carried by a single axle (front or rear).These
numbers are shown on the Safety Compliance Certification Label
located on the driver's door or door pillar. The total load on each
axle must never exceed its GAWR.
WARNING: Exceeding the Safety Certification Label axle
weight rating limits could result in substandard vehicle
handling, performance, engine, transmission and/or structural
damage, serious damage to the vehicle, loss of control and
personal injury.
Note:For trailer towing information refer toTrailer Towingfound in
this chapter or the RV and Trailer Towing Guide provided by your
dealership.
GVW (Gross Vehicle Weight)± is the Vehicle Curb Weight + cargo +
passengers.
Driving
125

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 driver's
door or door pillar. The GVW
must never exceed the GVWR.
WARNING: Exceeding the Safety Certification Label axle
weight rating limits could result in substandard vehicle
handling, 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 weighing more than 680 kg
[1,500 lbs]).The GCW must never exceed the GCWR.

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.
