Brake Fluid Type ▶ 1. Color
Ligh gold (New oil) → Brown → Black -
2. Service Interval/Type
Change: every 2 years, Type: DOT4
The water in the brake fluid has an adverse effect to the brake system. If the fluid contains
around 3% of water, the boiling point of the brake fluid goes down by 25%. It will cause the vapor
lock frequently.
Water content in fluid: around 3% after 18 months, around 7~10% after few years
The water ib fluid makes the corrosion in the brake lines, deforms and deteriorates the rubber
components, brake calipers and pistons. -
DOT4: Brake fluid for premium vehicle. Lower water absorbing rate AND higher boiling point than
DOT3
Brake Fluid Level Check ▶
The brake fluid level should be between "MAX"
and "MIN" on the reservoir. If it is below "MIN"
mark, check for oil leaks and refill the reservoir
with the specified fluid.

1. SYSTEM OVERVIEW
1) What is ABS?
When braking suddenly or braking on slippery roads, the vehicle keeps moving forward but the wheels
are locking and not rotating. If these happen, the vehicle may lose stability or rotate resulting in an
accident. ABS helps to maintain directional stability and control of the vehicle. ABS is designed to
secure more safety and increase the control of steering wheel during emergency braking situation. But,
ABS does not guarantee perfect safety beyond its physical limit. ABS in this vehicle contains EBD
function. In normal driving conditions, the brake system operates without ABS function.
2) What is EBD (Electronic Brake-force Distribution)?
EBD is an automobile brake technology that automatically varies the amount of force applied to each of a
vehicle's brakes, based on road conditions, speed, loading, etc. Always coupled with anti-lock braking
systems, EBD can apply more or less braking pressure to each wheel in order to maximize stopping
power whilst maintaining vehicular control. EBD does not operate when ABS is working.
