If Trouble Arises
Overheating
Overheating
If the High engine coolant temperature
warning light illuminates, the vehicle loses
power, or you hear a loud knocking or
pinging noise, the engine is probably too
hot.
WARNING
Switch the ignition to 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 indefi nitely 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 High engine coolant temperature
warning light illuminates:
1. Drive safely to the side of the road and park off the right-of-way.
2. Put a vehicle with an automatic transaxle in park (P), a manual
transaxle 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.

Seat belt reminder
NOTE
Consult an Authorized Mazda Dealer to deactivate or restore the belt reminder. Though the belt
reminder can be deactivated, doing so will defeat the purpose of the syst\
em to warn the driver and
the front passenger in the event that their seat belts are not fastened. For the safety of the driver
and front passenger, Mazda recommends not deactivating the belt reminder.
Front seat
If the vehicle is driven with the driver or front passenger's seat belt \
unfastened, the seat belt
warning light illuminates and a warning beep sounds.
NOTE
Some models do not have the seat belt reminder function for the front passenger's seat.
If the driver or front passenger's seat belt is unfastened (only when t\
he front passenger seat is
occupied) and the vehicle is driven at a speed faster than about 20 km/\
h (12 mph), the warning light
will fl ash and a beep sound will be heard. After a short time, the warning light stops fl ashing, but
remains illuminated, and the beep sound stops.
Until a seat belt is fastened or a given period of time has elapsed, the\
beep sound will not stop even
if the vehicle speed falls below 20 km/h (12 mph).
NOTE
yThe warning light fl ashes and a beep sound will be heard for about 6 seconds if the driver's seat
belt is not fastened when the ignition is switched ON.
y If a driver or front passenger's seat belt is unfastened after the beep sound turns off (\
warning light remains illuminated), and the vehicle speed exceeds 20 km/h (12 mph), \
the warning light fl ashes
and beep sound activates again.
yPlacing heavy items on the front passenger seat may cause the front passenger seat belt warning function to operate depending on the weight of the item.
yTo allow the front passenger seat weight sensor to function properly, do not place and sit on an additional seat cushion on the front passenger seat. The sensor may not function properly
because the additional seat cushion could cause sensor interference.
y When a small child sits on the front passenger seat, it is possible that the warning light will not operate.
Door-Ajar Warning Light The light turns on if any door is not closed
securely.
Close the door securely.
