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
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.
SeeAdding coolantin theMaintenance and specificationssection. 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.
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; doing so may
damage the catalytic converter.
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 vehiclesdo nottouch. 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 (+) jumper cable to the positive (+) terminal of
the discharged battery.
Note:In the illustrations,lightning boltsare used to designate the
assisting (boosting) battery.
2. Connect the other end of the positive (+) cable to the positive (+)
terminal of the assisting battery.

Do not use supplemental engine oil additives, oil treatments or engine
treatments. They are unnecessary and could, under certain conditions,
lead to engine damage which is not covered by your warranty.
Change your engine oil according to the appropriate schedule listed in
the service maintenance section.
Engine Oil Filter Recommendation
Change your engine oil filter according to the appropriate schedule listed
in the service maintenance section. Mazda production and aftermarket
(Mazda) oil filters are designed for added engine protection and long life.
If a replacement oil filter is used that does not meet Mazda Material and
design specifications, start-up engine noises or knock may be
experienced.
It is recommended you use the appropriate Mazda oil filter (or another
brand meeting Mazda specifications) for your engine.
BATTERY
Your vehicle is equipped with a
Mazda maintenance-free battery
which normally does not require
additional water during its life of
service.
However, for severe usage or in high temperature climates, check the
battery electrolyte level. Refer to theService Maintenance Sectionfor
the service interval schedules.
Keep the electrolyte level in each cell up to the“level indicator”.
Do not overfill the battery cells.
If possible, try to only fill the battery cells with distilled water. If the
battery needs water often, have the charging system checked.
If your battery has a cover/shield, make sure it is reinstalled
after the battery has been cleaned or replaced.
