Driving while you tow
When towing a trailer:
• Turn off the speed control. The speed control may shut off
automatically when you are towing on long, steep grades.
• Consult your local motor vehicle speed regulations for towing a trailer.
• To eliminate excessive shifting, use a lower gear. This will also assist
in transmission cooling. (For additional information, refer to the
Driving with a 5–speed automatic transmission section in this
chapter.
• Under extreme conditions with large frontal trailers, high outside
temperatures and highway speeds, the coolant gauge may indicate
higher than normal coolant temperatures. If this occurs, reduce speed
until the coolant temperature returns to the normal range. Refer to
Engine coolant temperature gauge in theInstrument cluster
chapter.
• Anticipate stops and brake gradually.
• Do not exceed the GCWR rating or transmission damage may occur.
Servicing after towing
If you tow a trailer for long distances, your vehicle will require more
frequent service intervals. Refer to your service maintenance section for
more information.

4x2 equipped with a manual transmission:
Before you have your vehicle towed:
•Release the parking brake.
• Move the gearshift to the neutral position.
• Turn the key in the ignition to the OFF/UNLOCKED position.
• The maximum recommended speed is 88 km/h (55 mph).
• The maximum recommended distance is unlimited.
• The vehicle must be towed in the forward position to ensure no
damage is done to the internal transfer case components.
In addition, it is recommended that you follow the instructions
provided by the aftermarket manufacturer of the towing
apparatus if one has been installed.
4x2 equipped with automatic transmission and 4x4 vehicles:
4x2 vehicles with automatic transmissions or 4x4 vehicles with an
electronic-shift transfer case and automatic transmission, follow these
guidelines for recreational towing:
• Release the parking brake.
• Turn the key in the ignition to the OFF/UNLOCKED position.
• Place the transmission in N (Neutral).
• Do not exceed a distance of 80 km (50 miles).
• Do not exceed 56 km/h (35 mph) vehicle speed.
• The vehicle must be towed in the forward position to ensure no
damage is done to the internal transfer case components.
If a distance of 80 km (50 miles) or a speed of 56 km/h (35 mph) must
be exceeded, you must disconnect the front (4x4 only) and rear
driveshafts. Mazda recommends the driveshafts be removed/installed only
by a qualified technician. See your local dealer for driveshaft
removal/installation.
Improper removal/installation of the driveshaft can cause
transmission fluid or transfer case fluid loss, damage to the
driveshaft and internal transmission and transfer case
components.
CAMPER BODIES
Your pickup is not recommended for slide–in camper bodies.

HAZARD FLASHER
The hazard flasher is located on the
steering column, just behind the
steering wheel. The hazard flashers
will operate when the ignition is in
any position.
Push in the flasher control and all
front and rear direction signals will
flash. Press the flasher control again
to turn them off. Use it when your
vehicle is disabled and is creating a
safety hazard for other motorists.
Note:With extended use, the flasher may run down your battery.
FUEL PUMP SHUT-OFF SWITCH
FUEL
RESET
This device stops the electric fuel pump from sending fuel to the engine
when your vehicle has had a substantial jolt.
After an accident, if the engine cranks but does not start, this switch
may have been activated.
Roadside Emergencies
139

This switch is located in the front
passenger’s footwell, by the kick
panel access cover.
To reset the switch:1. Turn the ignition OFF.
2. Check the fuel system for leaks.
3. If no leaks are apparent, reset the switch by pushing in on the
reset button.
4. Turn the ignition ON.
5. Wait a few seconds and return the key to OFF.
6. Make another check of leaks.
FUSES AND RELAYS
Fuses
If electrical components in the
vehicle are not working, a fuse may
have blown. Blown fuses are
identified by a broken wire within
the fuse. Check the appropriate
fuses before replacing any electrical
components.
Note: Always replace a fuse with one that has the specified amperage
rating. Using a fuse with a higher amperage rating can cause severe wire
damage and could start a fire.

4. Check whether coolant or steam is escaping from under the hood orfrom the engine compartment.
• If steam is coming from the engine compartment:do not go near
the front of the vehicle. Stop the engine, then turn the ignition switch
to the ON position without starting the engine. The radiator cooling
fans will start to cool the engine.
• If neither coolant nor steam is escaping: open the hood and idle
the engine until it cools. If this does not lower the temperature, stop
the engine and let it cool.
5. Check the coolant level. If it is low, look for leaks in the radiator hoses and connections, heater hoses and connections, radiator and
water pump.
If you find a leak or other damage, or if coolant is still leaking, stop the
engine and call an Authorized Mazda dealer.
See Adding coolant in theMaintenance and specifications section. If
you find no problems, the engine is cool and no leaks are obvious,
carefully add coolant as required.
WARNING: When the engine and radiator are hot, scalding
coolant and steam may shoot out under pressure and cause
serious injury. Do not remove the cooling system cap when the
engine and radiator are hot.
Note: If the engine continues to overheat or frequently overheats, have
the cooling system inspected. The engine could be seriously damaged
unless repairs are made.
CHANGING THE TIRES
If you get a flat tire while driving, do not apply the brake heavily.
Instead, gradually decrease your speed. Hold the steering wheel firmly
and slowly move to a safe place on the side of the road.
WARNING: The use of tire sealants is not recommended and
may compromise the integrity of your tires.
