Check the fluid level when it is at ambient temperature, 20°F–80°F
(-7°C–25°C):
1. Check the fluid level on the dipstick. It should be between the arrows
in the FULL COLD range. Do not add fluid if the level is within this
range.
2. If the fluid level is low. Add fluid to bring fluid level up to be between
the arrows in the FULL COLD range.
3. Start the engine.
4. While the engine idles, turn the steering wheel left and right several
times.
5. Turn the engine off.
6. Recheck the fluid level on the dipstick. Do not add fluid if the level is
between the arrows in the FULL COLD range.
7. If the fluid is low, add fluid in small amounts, continuously checking
the level until it reaches the FULL COLD range. Be sure to put the
dipstick back in the reservoir.
BRAKE FLUID
The fluid level will drop slowly as
the brakes wear, and will rise when
the brake components are replaced.
Fluid levels between the “MIN” and
“MAX” lines are within the normal
operating range; there is no need to
add fluid. If the fluid levels are
outside of the normal operating
range the performance of your
brake system could be
compromised; seek service from
your authorized dealer immediately.
CLUTCH FLUID (IF EQUIPPED)
Check the clutch fluid level. Refer to the scheduled maintenance
information for the service interval schedules.
