WARNING: If you use a brake fluid that is not DOT 3, you will
cause permanent damage to your brakes.
WARNING: Do not let the reservoir for the master cylinder run
dry. This may cause the brakes to fail.
CLUTCH FLUID (IF EQUIPPED)
Check the fluid level. Refer to the service maintenance section for the
service interval schedules.
During normal operation, the fluid level in the clutch reservoir should
remain constant. If the fluid level drops, refill the fluid level to the step
in the reservoir.
Use only a DOT 3 brake fluid designed to meet Mazda specification.
Refer toLubricant Specificationsin this chapter.
WARNING: Brake fluid is toxic. If brake fluid contacts the
eyes, flush eyes with running water for 15 minutes. Seek
medical attention if irritation persists. If taken internally, drink
water and induce vomiting. Seek medical attention immediately.
1. Clean the reservoir cap before
removal to prevent dirt and
water from entering the
reservoir.
2. Remove cap and rubber
diaphragm from reservoir.
3. Add fluid until the level reaches
the step in the reservoir.
4. Reinstall rubber diaphragm and
cap onto reservoir.

fluid requirements are indicated on the dipstick or on the dipstick
handle. MERCONand MERCONV are not interchangeable. DO NOT
mix MERCONand MERCONV. Refer to theService Maintenance
Sectionto determine the correct service interval.
2Service refill capacity is determined by filling the transmission to the
bottom of the filler hole with the vehicle on a level surface.
3Indicates only approximate dry-fill capacity. Some applications may vary
based on cooler size and if equipped with an in-tank cooler. The amount
of transmission fluid and fluid level should be set by the indication on
the dipstick’s normal operating range.
4Add the coolant type originally equipped in your vehicle. DO NOT MIX
different colors or types of coolant. DO NOT USE Mazda Extended Life

4Brake fluid will drop slowly as the brakes wear and will rise when brake
components are replaced. Fluid levels below the MAX line that do not
trigger the brake warning light are within the normal operating range,
there is no need to add fluid. If the levels are outside the normal
operating range, the performance of your brake system could be
compromised, seek service from your local Mazda dealer immediately.
