Inspecting Power Steering Fluid 
Level
Inspect the fluid level in the reservoir at 
each engine oil change with the engine off 
and cold. Add fluid if necessary; it does 
not require periodic changing.
The level must be kept between MIN and 
MAX.
Visually examine the lines and hoses for 
leaks and damage.
If new fluid is required frequently, consult 
an Authorized Mazda Dealer.
•
Brake and clutch fluid will damage 
painted surfaces. If brake or clutch 
fluid does get on a painted surface, 
wipe it off immediately.
• Using nonspecified brake and clutch 
fluids (page 10-4) will damage the 
systems. Mixing different fluids 
will also damage them.
If the brake/clutch system 
frequently requires new fluid, 
consult an Authorized Mazda 
Dealer.
CAUTIONPower Steering Fluid
To avoid damage to the power steering 
pump, don
’t operate the vehicle for 
long periods when the power steering 
fluid level is low.
NOTE
Use specified power steering fluid 
(page 10-4).

Replacing a TireIf a tire wears evenly, a wear indicator will 
appear as a solid band across the tread.
Replace the tire when this happens.
You should replace it before the band is 
across the entire tread.
 Temporary Spare Tire
Inspect the temporary spare tire at least 
monthly to make sure it
’s properly 
inflated and stored.
The temporary spare tire is easier to 
handle because of its construction. It is 
lighter and smaller than a conventional 
tire and should be used only for an 
emergency and only for a short distance.
Use the temporary only until the 
conventional tire is repaired, which should 
be as soon as possible.
Maintain its pressure at 420 kPa (4.2 kgf/
cm
2 or bar, 60 psi).
Worn Tires:
Driving with worn tires is dangerous.
Reduced braking, steering, and 
traction could result in an accident.
Always use tires that are in good 
condition.
(With Tire Pressure Monitoring 
System)  
When replacing/repairing the tires or 
wheels or both, have the work done by 
an Authorized Mazda Dealer, or the 
tire pressure sensors may be damaged.
NOTE
(With Tire Pressure Monitoring 
System)  
• When tires with steel wire 
reinforcement in the sidewalls are 
used, the system may not function 
correctly even with a genuine 
wheel. (page 5-24)
• Be sure to install the tire pressure 
sensors whenever tires or wheels are 
replaced. (page 5-24)
