•
Contact with discharged fluids that may cause
injury due to heat, cold, or toxicity.
•
Electrocution from electric power lines.
•
Whipping hoses.
•
Sparking or explosion caused by static electric-
ity buildup or other sources of electricity.
•
Sparking or explosion while spraying paint or
flammable liquids.
•
Injuries resulting from inhalation, ingestion, or
exposure to fluids.
1. With the ignition switch in the OFF position, visu-
ally inspect the hydraulic system for fluid leaks.
If any leaks are found, contact a certified hydrau-
lic hybrid service technician to determine the cor-
rective action to take.
2. Inspect the hydraulic system hose(s) and fit-
ting(s).
High pressure hoses used on the hydraulic hy-
brid system can be identified by their orange
wrapping. Low pressure hoses are wrapped in
black.
If any of the following conditions are found, con-
tact a certified hydraulic hybrid service technician
to complete a system pressure bleed-down of
the hydraulic hybrid system, and replace the
hose assembly:
•
fitting slippage on the hose
•
exposed reinforcement
•
damaged, cracked, cut, or abraded cover
•
hard, stiff, heat cracked, or charred hose(s)
•
leaks at the fitting(s) or in the hose(s)
•
kinked, crushed, flattened, or twisted
hose(s)
•
blistered, soft, degraded, or loose cover
•
bulges in the hose(s)
NOTICE
If the low pressure reservoir (LPR) fluid level is
not even with or higher than the LOW indicator
marks on the sight glass, do not start the vehicle.
LPR pressure should be between 35 to 70 psi
Hydraulic Hybrid
(241 to 483 kPa). Operating the vehicle with a low
LPR fluid level will result in damage to the hy-
draulic hybrid system.
3.
Check the LPR fluid level and pressure.
With the ignition switch in the OFF position,
verify that the LPR fluid level and pressure are
correct. The fluid level should be even with or
higher than the LOW indicator marks on the sight
glass, as shown in
not even with or higher than the LOW indicator
marks, contact a certified hydraulic hybrid service
technician to determine the corrective action to
take before proceeding.
Press the valve below the gauge, shown in
Fig. 16.15, to read the LPR pressure. The pres-
sure should be between 35 to 70 psi (241 to 483
kPa). If the pressure is not within this range, con-
tact a certified hydraulic hybrid service technician
to determine the corrective action to take before
proceeding.

4. Check the active warning indicators.
When the ignition switch is turned to the ON po-
sition, the warning indicators in the instrument
panel will illuminate for a self-test and then turn
off. If the check transmission or stop transmis-
sion indicator(s) remain illuminated after the self-
test has completed, contact a certified hydraulic
hybrid technician to determine the corrective ac-
tion to take before starting the vehicle.
