Jump-Starting
▼Jump-Starting
Jump-starting is dangerous if done incorrectly. So follow the procedure carefully. If
you feel unsure about jump-starting, we strongly recommend that you have a
competent service technician do the work.
WARNING
Follow These Precautions Carefully:
To ensure safe and correct handling of the battery, read the following precautions
carefully before using the battery or inspecting it.
Keep flames and sparks away from open battery cells and do not allow
metal tools to contact the positive (+) or negative (–) terminal of the battery when
working near a battery. Do not allow the positive (+) terminal to contact the
vehicle body:
Flames and sparks near open battery cells are dangerous. Hydrogen gas, produced
during normal battery operation, could ignite and cause the battery to explode. An
exploding battery can cause serious burns and injuries. Keep all
flames including
cigarettes and sparks away from open battery cells.
Keep all
flames and sparks away from open battery cells because hydrogen
gas is produced from open battery cells while charging the battery or adding
battery
fluid:
Flames and sparks near open battery cells are dangerous. Hydrogen gas, produced
during normal battery operation, could ignite and cause the battery to explode. An
exploding battery can cause serious burns and injuries. Keep all
flames including
cigarettes and sparks away from open battery cells.
Do not jump-start a frozen battery or one with a low fluid level:
Jump-starting a frozen battery or one with a low fluid level is dangerous. It may
rupture or explode, causing serious injury.
Connect the negative lead to a good ground point away from the battery:
Connecting the end of the second jumper lead to the negative (–) terminal of the
discharged battery is dangerous.
A spark could cause the gas around the battery to explode and injure someone.
If Trouble Arises
Battery Runs Out
7-39

Route the jumper leads away from parts that will be moving:
Connecting a jumper lead near or to moving parts (cooling fans, belts) is dangerous.
The lead could get caught when the engine starts and cause serious injury.
CAUTION
Use only a 12 V booster system. You can damage a 12 V starter, ignition system, and
other electrical parts beyond repair with a 24 V power supply (two 12 V batteries in
series or a 24 V motor generator set).
1. Move the booster vehicle so that its battery is as close as possible to your
vehicle's battery.
2. Make sure that the power such as for the headlights and air conditioner is turned
off.
3. Remove the battery cover.
4. Turn off the booster vehicle's engine and connect the jumper leads in the
following order.
Make sure that the jumper leads are securely connected so that they do not
disconnect due to engine vibrations.

5. Start the booster vehicle's engine and rev the engine.
6. Start the engine of your vehicle. Run the engines for about 3 minutes to
temporarily charge the battery of your vehicle.
7. Disconnect the jumper leads in the reverse order of their connection.
8. Install the battery cover.
9. Have your vehicle inspected by an expert repairer (we recommend an Authorised
Mazda Repairer) as soon as possible.

Starting a Flooded Engine
(SKYACTIV-G 2.0,
SKYACTIV-G 2.5 and
SKYACTIV-X 2.0)
▼Starting a Flooded Engine
If the engine fails to start, it may be
flooded (excessive fuel in the engine).

Follow this procedure:

1. If the engine does not start within 5
seconds on the first try, wait 10
seconds and try again.
2. Make sure the parking brake is on.
3. Depress the accelerator all the way
and hold it there.
4. Depress the clutch pedal (manual
transmission) or the brake pedal
(automatic transmission), then
press the push button start. If the
engine starts, release the
accelerator immediately because
the engine will suddenly rev up.
5. If the engine fails to start, crank it
without depressing the accelerator.

If the engine still does not start using
the previous procedure, have your
vehicle inspected by an expert repairer
(we recommend an Authorised Mazda
Repairer).
Push-Starting
▼Push-Starting
Do not push-start your Mazda.
WARNING
Never tow a vehicle to start it:
Towing a vehicle to start it is
dangerous. The vehicle being towed
could surge forward when its engine
starts, causing the 2 vehicles to collide.
The occupants could be injured.
CAUTION
Do not push-start a vehicle that has a
manual transmission. It can damage
the emission control system.
NOTE
You cannot start a vehicle with an
automatic transmission by pushing it.
If Trouble Arises
Emergency Starting
7-42

Running Out of Fuel
(SKYACTIV-D 1.8)
▼Running Out of Fuel
CAUTION
Do not try starting the engine for more
than 10 seconds at a time. Doing so,
could damage the starter. If the engine
does not start on the first try wait
about 20 seconds before trying again.
If your vehicle runs out of fuel, add at
least 10 L (2.6 US gal, 2.2 Imp gal) of
diesel fuel, and try to restart the
engine. Because air can get into fuel
lines when a vehicle runs out of fuel,
your engine may take longer to start. If
the engine does not start the first time,
try starting it several more times. If it
still does not start, contact an expert
repairer (we recommend an
Authorised Mazda Repairer).
If Trouble Arises
Emergency Starting
7-43

Overheating
▼Overheating
If the engine coolant temperature
gauge indicates overheating and the
high engine coolant temperature
warning indication is displayed, the
vehicle loses power or you hear a loud
knocking or pinging noise, the engine
is probably too hot.
WARNING
Pull over to a safe location, then
switch the ignition off and make sure
the fan is not running before
attempting to work near the cooling
fan:
Working near the cooling fan when it is
running is dangerous. The fan could
continue running
indefinitely even if
the engine has stopped and the engine
compartment temperature is high. You
could be hit by the fan and seriously
injured.
Do not remove either
cooling system cap when the engine
and radiator are hot:
When the engine and radiator are hot,
scalding coolant and steam may shoot
out under pressure and cause serious
injury.
Open the bonnet ONLY after steam is
no longer escaping from the engine:
Steam from an overheated engine is
dangerous. The escaping steam could
seriously burn you.
If the engine coolant temperature
gauge indicates overheating and the
high engine coolant temperature
warning indication is displayed:

1. Drive safely to the side of the road
and park off the right-of-way.
2. Put a vehicle with an automatic
transmission in park (P), a manual
transmission in neutral.
3. Apply the parking brake.
4. Turn off the air conditioner.
5. Check whether coolant or steam is
escaping from the engine
compartment.

If steam is coming from the engine
compartment:
Do not go near the front of the
vehicle. Stop the engine.
Wait until the steam dissipates,
then open the bonnet and start the
engine.

If neither coolant nor steam is
escaping:
Open the bonnet and idle the
engine until it cools.
CAUTION
If the cooling fan does not operate
while the engine is running, the
engine temperature will increase.
Stop the engine and call an expert
repairer (we recommend an
Authorised Mazda Repairer).
6. Make sure the cooling fan is
operating, then turn off the engine
after the temperature has
decreased.
7. When cool, check the coolant level.
If Trouble Arises
Overheating
7-44

If it is low, look for coolant leaks
from the radiator and hoses.

If you find a leak or other damage, or
if coolant is still leaking:
Stop the engine and call an expert
repairer (we recommend an
Authorised Mazda Repairer).
1. Cooling system cap
2. Cooling fan
3. Coolant reservoir

If you find no problems, the engine is
cool, and no leaks are obvious:
Carefully add coolant as required
(page 6-28).
CAUTION
If the engine continues to overheat or
frequently overheats, have the cooling
system inspected. The engine could be
seriously damaged unless repairs are
made. Consult an expert repairer (we
recommend an Authorised Mazda
Repairer).

Towing Description
▼Towing Description
We recommend that towing be done
only by an expert repairer (we
recommend an Authorised Mazda
Repairer) or a commercial tow-truck
service.

Proper lifting and towing are necessary
to prevent damage to the vehicle.
Particularly when towing a AWD
vehicle, where all the wheels are
connected to the drive train, proper
transporting of the vehicle is absolutely
essential to avoid damaging the drive
system. Government and local laws
must be followed.
1. Wheel dollies

A towed FWD vehicle should have its
drive wheels (front wheels)
off the
ground. If excessive damage or other
conditions prevent this, use wheel
dollies.

When towing a FWD vehicle with the
rear wheels on the ground, release the
parking brake.
Refer to Electric Parking Brake (EPB) on
page 4-70.

A towed AWD vehicle must have all its
wheels
off the ground.
WARNING
Always tow a AWD vehicle with all
four wheels
off the ground:
Towing a AWD vehicle with either the
front or rear wheels on the ground is
dangerous as the drive train could be
damaged, or the vehicle could trail
away from the tow truck and cause an
accident. If the drive train has been
damaged, transport the vehicle on a
flatbed truck.
CAUTION
¾Do not tow the vehicle pointed
backward with driving wheels on the
ground. This may cause internal
damage to the transmission.
¾Do not tow with sling-type
equipment. This could damage your
vehicle. Use wheel-lift or flatbed
equipment.
