CHECKING BRAKE FLUID
To check the fluid level, simply look at the see±through
reservoir. The level should be between the ºMAXº and
ºMINº lines on the tank.

CHASSIS
360It is normal for the brake fluid level to go down slightly as the
brake pads wear. So be sure to keep the reservoir filled.
If the reservoir needs frequent refilling, it may indicate a
serious mechanical problem.
If the level is low, add FMVSS No.116 DOT 3 or SAE
J1703 brake fluid to the brake reservoir.
Remove and replace the reservoir cover by hand. Add brake
fluid up to the ºMAXº line.
Use only newly opened brake fluid. Once opened, brake fluid
absorbs moisture from the air, and excess moisture can cause
a dangerous loss of braking efficiency.
CAUTION
Take care when filling the reservoir because brake fluid can
harm your hands or eyes and damage painted surfaces. If
fluid gets in your hands or eyes, flush them with clean water.
NOTICE

If you spill some of the fluid, be sure to wipe it off to
prevent it from damaging the parts or paintwork.
 For vehicles with traction control system only:Idle
the engine while pouring brake fluid into the reservoir.

CHECKING POWER STEERINGFLUID
Check the fluid level on the dipstick. If necessary, add
automatic transmission fluid DEXRONII or III.

CHASSIS
362If the vehicle has been driven around 80 km/h (50 mph) for
20 minutes (a little more in frigid temperatures), the fluid is
hot (60C ± 80C or 140F ± 175F). You may also check
the level when the fluid is cold (about room temperature,
10 C ± 30C or 50F ± 85 F) if the engine has not been run
for about five hours.
1. Clean all dirt off the reservoir.
2. Remove the filler cap by turning it counterclockwise and
wipe the dipstick clean.
3. Reinstall the filler cap.
4. Remove the filler cap again and look at the fluid level. If
the fluid is cold, the level should be in the ºCOLDº range on
the dipstick. Similarly, if it is hot, the fluid level should be in
the ºHOTº range. If the level is at the low side of either range,
add automatic transmission fluid DEXRON
II or III to bring
the level within the range. 5. After replacing the filler cap, visually check the steering
box case, vane pump and hose connections for leaks or
damage.
