Spring Preload Adjustment

The front and rear shock absorber springs are adjustable by
rotating the adjustment cam to change spring tension preload.
WARNING
Uneven adjustment may cause poor handling of the
vehicle, which could result in an accident and
serious injury or death. Always adjust all spring
preloads equally.

BRAKE SYSTEM

Brake Fluid Inspection

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
should 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 left front wheel well.
1. Position the vehicle on a level surface. Engine off.
2. Place the transmission in gear and lock the parking brake.
3. View the brake fluid level in the reservoir. The level should
be between the MAX and MIN level lines.
4. If the fluid level is lower than the MIN level line, add brake
fluid until it reaches the MAX level line.
5. Install the reservoir cap and apply the brake pedal
forcefully for a few seconds, then check for fluid leaks
around the master cylinder and brake caliper fittings.
