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.
See Adding coolant in theMaintenance 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 may damage your tires.
Temporary spare tire information (if equipped)
Your vehicle may be equipped with a conventional spare tire that may be
different in size (smaller diameter and narrower width) than other tires
on your vehicle. If this is the case, your spare tire is considered
“temporary” and the spare wheel will be labeled as such. Replace this
tire with a tire of the same size, speed rating and load carrying capacity
as the other road tires as soon as possible.
It is not recommended that the vehicle be operated in 4WD modes with
a “temporary” (i.e. dissimilar size) spare. If 4WD operation is necessary,
do not operate above speeds of 16 km/h (10 mph) or for distances above
80 km (50 miles).
WARNING: If you use the temporary spare tire continuously or
do not follow these precautions, the tire could fail, causing you
to lose control of the vehicle, possibly injuring yourself or
others.
When driving with the temporary spare tire do not:
• exceed 80 km/h (50 mph) or drive further than 3,200 km (2,000
miles) total under any circumstances
• load the vehicle beyond maximum vehicle load rating listed on the
Safety Compliance Label
• tow a trailer
• use more than one temporary spare tire at a time
Use of a temporary spare tire at any one wheel location can lead to
impairment of the following:
• Handling, stability and braking performance
• Comfort and noise
• Ground clearance and parking at curbs
• Winter driving capability
