stopping distance. See Maintenance
Schedule 0303.
Checking Brake Fluid
Check brake fluid by looking at the
brake fluid reservoir. See Engine

the loss of braking leading to a
possible injury. Always use the
proper GM approved brake fluid.
Caution
If brake fluid is spilled on the
vehicle's painted surfaces, the
paint finish can be damaged.
Immediately wash off any painted
surface.
