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.

• 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

Roadside Emergencies

151

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 the Maintenance 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.

Conventional spare tire information

If you have the conventional spare tire, you can use it as a spare or a
regular tire. The spare is identical to the other tires on your vehicle,
although the wheel may not match.

Roadside Emergencies

152

Location of the spare tire and tools

The spare tire and tools for your vehicle are stowed in the following
locations:

Tool

Location

Spare tire

Under the vehicle, just forward of
the rear bumper

Jack, jack handle, wheel nut

wrench

Regular Cab: behind seats and
underneath the jack and tools
cover

Cab Plus: stowed in the passenger
side rear cab compartment or
behind the jump seat in a separate
tool bag

Cab Plus 4–Door: stowed behind
the front seats, between jump
seats and underneath jack and
tools cover.

Key, spare tire lock (if equipped)

In the glove box

Removing the spare tire

1. Assemble the jack handle to the lug wrench as shown in the

illustrations.

When connecting the jack handle, assemble the following:
• one handle extension and one

typical extension. To assemble,
slide parts together. To
disconnect, depress button and
pull apart.

• one wheel nut wrench. Depress

button and slide together.

Roadside Emergencies

153

2. If equipped, unlock and remove

the spare tire carrier lock from
the rear access hole located just
above the rear bumper and
below the tailgate.

3. Insert the straight end of the

jack handle into the rear access
hole located just above the rear
bumper and below the tailgate.

Forward motion will stop and
resistance to turning will be felt
when properly engaged.

4. Turn the handle

counterclockwise until tire is
lowered to the ground and the cable is slightly slack.

5. Remove the retainer from the spare tire.

Stowing the spare tire

1. Lay the tire on the ground with the valve stem facing up.

2. Install the retainer through the

wheel center and slide the
wheel under the vehicle.

3. Turn the spare handle clockwise

until the tire is raised to its
original position underneath the
vehicle. The spare handle
ratchets when the tire is raised
to the stowed position. It will
not allow you to overtighten.

Roadside Emergencies

154

4. If your vehicle is equipped with P265/75 R15 AT tires, do not stow a

flat or inflated full size spare tire in the spare tire carrier. The flat
full size tire should be stowed and tied down in the pickup box bed
until it can be repaired.

5. If removed, install the spare tire carrier lock on the access hole

above the bumper.

Tire change procedure

WARNING: When one of the front wheels is off the ground, the
transmission alone will not prevent the vehicle from moving or
slipping off the jack, even if the vehicle is in P (Park)
(automatic transmission) or R (Reverse) (manual
transmission).

WARNING: To prevent the vehicle from moving when you
change a tire, be sure the parking brake is set, then block (in
both directions) the wheel that is diagonally opposite (other
side and end of the vehicle) to the tire being changed.

WARNING: If the vehicle slips off the jack, you or someone
else could be seriously injured.

1. Park on a level surface, activate

hazard flashers and place
gearshift lever in P (Park)
(automatic transmission) or 1
(First) (manual transmission).

2. Set the parking brake and turn

engine OFF.

Roadside Emergencies

155

3. Block the diagonally opposite

wheel.

4. Insert tapered end of the lug

wrench behind hub caps and
twist them off.

5. Loosen each wheel lug nut

one-half turn counterclockwise
but do not remove them until
the wheel is raised off the
ground.

6. Position the jack according to

the following guides and turn
the jack handle clockwise until the tire is a maximum of 25 mm
(1 inch) off the ground.

WARNING: To lessen the risk
of personal injury, do not put
any part of your body under
the vehicle while changing a
tire. Do not start the engine
when your vehicle is on the
jack. The jack is only meant
for changing the tire.

• Front

Roadside Emergencies

156

• Rear

Never use the differential as a
jacking point. It is too easy for
the vehicle to tilt or fall and you
can be injured.

7. Remove the wheel lug nuts with

the lug wrench.

8. Replace the flat tire with the

spare tire, making sure the valve
stem is facing outward. Reinstall
the lug nuts until the wheel is
snug against the hub. Do not
fully tighten the lug nuts until the wheel has been lowered.

9. Lower the wheel by turning the jack handle counterclockwise.

10. Remove the jack and fully

tighten the lug nuts, in the
order shown, to 135 Nm
(100 lb-ft). Note that these
tightening specifications are for
nut and bolt threads that are
free of dirt and rust. Use only
Mazda recommended (1/2–20)
replacement fasteners.

11. Stow the flat tire. Refer to

Stowing the spare tire.

12. Stow the jack and lug wrench. Make sure the jack is fastened so it

does not rattle when you drive.

13. Unblock the wheels.

Roadside Emergencies

157

Stowing the flat/spare tire

1. Lay the tire on the ground with the valve stem facing up.

2. Slide the wheel partially under the vehicle and install the wire and

retainer through the center of the wheel.

3. Turn the jack handle clockwise until the tire is raised to its original

position underneath the vehicle. The effort to turn the jack handle
increases significantly as the tire contacts the frame. The spare tire
carrier will ratchet when the tire is in the fully stowed position. The
spare tire carrier has a built-in ratchet feature that will not allow you
to overtighten. If the spare tire carrier ratchets with very little effort,
take the vehicle to your dealer for assistance at your earliest
convenience.

4. Check that the tire lies flat against the frame assembly. Push against

the tire to make sure it is tightly sealed under the vehicle. Loosen
and retighten, if necessary. Failure to properly stow the spare tire
may result in failure of the winch cable and loss of the spare tire.

5. Repeat this tightness check procedure when servicing the spare tire

pressure (every six months, per service maintenance section), or at
any time that the spare tire is disturbed through service of other
components.

6. Install the spare tire lock (if equipped) into the access hole above

the rear bumper with the spare tire lock key (if equipped) and jack
handle.

JUMP STARTING YOUR VEHICLE

WARNING: The gases around the battery can explode if
exposed to flames, sparks, or lit cigarettes. An explosion could
result in injury or vehicle damage.

WARNING: Batteries contain sulfuric acid which can burn skin,
eyes and clothing, if contacted.

Do not attempt to push-start your vehicle. Automatic
transmissions do not have push-start capability; also, the
catalytic converter may become damaged.

Preparing your vehicle

When the battery is disconnected or a new battery is installed, the
transmission must relearn its shift strategy. As a result, the transmission
may have firm and/or soft shifts. This operation is considered normal and
will not affect function or durability of the transmission. Over time, the
adaptive learning process will fully update transmission operation.

1. Use only a 12–volt supply to start your vehicle.

2. Do not disconnect the battery of the disabled vehicle as this could

damage the vehicle’s electrical system.

3. Park the booster vehicle close to the hood of the disabled vehicle

making sure the two vehicles do not touch. Set the parking brake on
both vehicles and stay clear of the engine cooling fan and other
moving parts.

4. Check all battery terminals and remove any excessive corrosion

before you attach the battery cables. Ensure that vent caps are tight
and level.

5. Turn the heater fan on in both vehicles to protect any electrical

surges. Turn all other accessories off.

Connecting the jumper cables

1. Connect the positive (+) booster cable to the positive (+) terminal of

the discharged battery.

Note: In the illustrations, lightning bolts are used to designate the
assisting (boosting) battery.

4. Make the final connection of the negative (-) cable to an exposed

metal part of the stalled vehicle’s engine, away from the battery and
the carburetor/fuel injection system. Do not use fuel lines, engine
rocker covers or the intake manifold as grounding points.

WARNING: Do not connect the end of the second cable to the
negative (-) terminal of the battery to be jumped. A spark may
cause an explosion of the gases that surround the battery.

5. Ensure that the cables are clear of fan blades, belts, moving parts of

both engines, or any fuel delivery system parts.

Jump starting

1. Start the engine of the booster vehicle and run the engine at

moderately increased speed.

2. Start the engine of the disabled vehicle.

3. Once the disabled vehicle has been started, run both engines for an

additional three minutes before disconnecting the jumper cables.

Removing the jumper cables

Remove the jumper cables in the reverse order that they were
connected.

1. Remove the jumper cable from the ground metal surface.

Note: In the illustrations, lightning bolts are used to designate the
assisting (boosting) battery.

2. Remove the jumper cable on the negative (-) connection of the

booster vehicle’s battery.

Roadside Emergencies

162

3. Remove the jumper cable from the positive (+) terminal of the

booster vehicle’s battery.

4. Remove the jumper cable from the positive (+) terminal of the

disabled vehicle’s battery.

After the disabled vehicle has been started and the jumper cables
removed, allow it to idle for several minutes so the engine computer can
relearn its idle conditions.

WRECKER TOWING

If you need to have your vehicle towed, contact a professional towing
service or, if you are a member, your roadside assistance center.

It is recommended that your vehicle be towed with a wheel lift or flatbed
equipment. Do not tow with a slingbelt. Mazda Motor Corporation has
not approved a slingbelt towing procedure.

On 4x2 vehicles, it is acceptable to tow the vehicle with the front wheels
on the ground and the rear wheels off the ground.

On 4x4 vehicles, it is recommended that your vehicle be towed with a
wheel lift and dollies or flatbed equipment with all the wheels off the
ground.

If the vehicle is towed by other means or incorrectly, vehicle
damage may occur.

Mazda Motor Corporation produces a towing manual for all authorized
tow truck operators. Have your tow truck operator refer to this manual
for proper hook-up and towing procedures for your vehicle.
