1.Park your vehicle on a level surface.
2.Look at the brake fluid reservoir to seewhere the brake fluid level is relativeto the MIN and the MAX marks on thereservoir.
Note:If the brake fluid level is between theMIN and the MAX marks on the reservoir, itis acceptable.
Note:If the brake fluid level is below theMIN mark or above the MAX mark, haveyour vehicle checked as soon as possible.
Note:To avoid fluid contamination, thereservoir cap must remain in place and fullytight, unless you are adding fluid.
Only use fluid that meets ourspecifications. See Capacities andSpecifications (page 337).
Brake Fluid Service Interval
Brake fluid absorbs water over time whichdegrades the effectiveness of the brakefluid. Change the brake fluid at thespecified intervals to prevent degradedbraking performance.
For detailed interval information, seeScheduled Maintenance in your Owner'sManual or your local maintenance guide.
CLUTCH FLUID CHECK -
MANUAL TRANSMISSION
The clutch and brake systems share thesame fluid reservoir. See Brake FluidCheck (page 270).
POWER STEERING FLUID
