Jump-Starting
▼Jump-Starting
Jump-starting is dangerous if done incorrectly. S
o follow the procedure carefully. If you feel
unsure about jump-starting, we strongly recommend that you have a competent service
technician do the work.
WA R N I N G
Follow These Precautions Carefully:
To ensure safe and correct handling of the ba ttery, 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 al l 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 cable to a good ground point away from the battery:
Connecting the end of the second jumper cable to the negative (–) terminal of the discharged
battery is dangerous.
A spark could cause the gas around the battery to explode and injure someone.
Route the jumper cables away from parts that will be moving:
Connecting a jumper cable near or to moving parts (cooling fans, belts) is dangerous. The
cable 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 p ossible to your vehicle's
battery.
2. Make sure that the power such as for the headlights and air c onditioner is turned off.
3. Remove the battery cover.
4. Turn off the booster vehicle's engine and connect the jumper cables in the following
order.
Make sure that the jumper cables are securely connected so that they do not disconnect
due to engine vibrations.

Starting a Flooded Engine
▼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 Authorized Mazda Dealer.
Push-Starting
▼ Push-Starting
Do not push-start your Mazda.
WA R N I N G
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.

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.
WA R N I N G
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 hood 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 hood and start the engine.

If neither coolant nor steam is
escaping:
Open the hood 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 Authorized Mazda
Dealer.

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 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 Authorized
Mazda Dealer.
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
6-17).
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 Authorized Mazda
Dealer.

▼Towing Description
We recommend that towing be done only
by an Authorized Mazda Dealer or a
commercial tow-truck service.

Proper lifting and towing are necessary to
prevent damage to the vehicle. Particularly
when towing an 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 ve hicle with the rear
wheels on the ground, release the parking
brake.
Refer to Electric Par king Brake (EPB) on
page 4-64.

A towed AWD vehicle must have all its
wheels off the ground.
WA R N I N G
Always tow an AWD vehicle with all four
wheels off the ground:
Towing an 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
 Do not tow the vehicle pointed backward
with driving wheels on the ground. This
may cause internal damage to the
transmission.

Mazda3_8HZ1-EA-19G_Edition1_old 2019-5-17 13:49:03

Do not tow with sling-type equipment.
This could damage your vehicle. Use
wheel-lift or
flatbed equipment.

If the parking brake cannot be released
when towing the vehicle, transport the
vehicle with all front and rear wheels
raised off the ground as shown in the
figure. If the vehicle is towed without
raising the wheels off the ground, the
brake system could be damaged.
1. Wheel dollies
Tiedown Hooks*
▼ Tiedown Hooks
CAUTION
Do not use the front and rear tiedown
eyelets for towing the vehicle.
They have been designed only for securing
the vehicle to a transport vessel during
shipping.
Using the eyelets for any other purpose
could result in the vehicle being damaged.
1. Remove the tiedown eyelet and the lug
wrench from the luggage compartment
(page 7-3).
2. Wrap a flathead screwdriver or similar tool with a soft cloth to prevent
damage to a painted bumper, and open
the cap located on the front or rear
bumper.
