Always check the brake pedal travel and inspect the brake
fluid reservoir level before each operation. If the fluid level
is low, add DOT 4 brake fluid only.
Brake fluid should be changed every two years. The fluid
sho
uld also be changed anytime the fluid becomes
contaminated, the fluid level is below the minimum level,
or if the type and brand of the fluid in the reservoir is
unknown.
The brake fluid master cylinder reservoir can be accessed
through the lef
t front wheel well.
1. Position the vehicle on a level surface.
2. Place the transmission in PARK (P).
3. View the brake fluid level in the reservoir. The level

el line, add
brake fluid until it reaches the MAX level line.

for
cefully for a few seconds and check for fluid
leakage around the master cylinder fittings and the
brake caliper fittings.
