Full (when cold)
Add fluid (when cold)
Full (when hot)
Add fluid (when hot)
Hot: Vehicle has been driven around 50 mph (80 km/h) for 20 min- utes, or slightly longer in frigid temperatures. (Fluid tempera-
ture, 140 °F - 175 °F [60 °C - 80 °C])
Cold: Engine has not been run for about 5 hours. (Room tempera- ture, 50 °F - 85 °F [10 °C - 30 °C])
CAUTION
■When filling the reservoir
Take care because brake fluid can harm your hands or eyes and damage painted
surfaces.
If fluid gets in your eyes, flush your eyes with clean water immediately.
If you still experience discomfort, see a doctor.
NOTICE
■If the fluid level is low or high
It is normal for the brake fluid level to go down slightly as the brake pads wear or
when the fluid level in the accumulator is high.
If the reservoir needs frequent refilling, it may indicate a serious problem.
