Hydraulic Hybrid

Safety Precautions

To ensure the safety of the driver, read and under-
stand the statements that follow before operating the
hydraulic hybrid vehicle.
DANGER
Warning labels are placed on various compo-
nents of the hydraulic hybrid drive system. Fail-
ure to read and follow the directions given can
lead to personal injury, loss of life, and vehicle or
component damage.
Never run hands, arms, or any other part of the
body over a hydraulic hose, line, fitting, or as-
sembly to check for leaks. A pinhole leak can re-
lease toxic fluid at more than 600 ft (183 m) per
second, acting as a hypodermic needle and pen-
etrating both protective clothing and skin at short
distances.
Never tighten or loosen a hydraulic connection
when the system is under pressure. The connec-
tion could fail catastrophically, causing personal
injury and/or damage to the vehicle. Make certain
that all high pressure is bled from the hydraulic
system before working on any connections.
Use extreme caution when working with hydrau-
lic hoses, lines, fittings, or assemblies during in-
stallation, preventive maintenance, or component
replacement. Fluids under high pressure can be
dangerous and potentially lethal. Make sure to
bleed all high pressure so that hoses and compo-
nents can be examined safely.
Discharging high pressure using the manual
bleed valve does not release the nitrogen gas
precharge pressure within the accumulator. The
nitrogen is under high pressure and can be dan-
gerous and potentially lethal if the accumulator is
punctured.
It takes approximately 10 minutes for high-
pressure fluid to discharge once the manual
bleed valve has been opened. Do not attempt to
work on the hybrid drive system until there is
verification that the high-pressure fluid has been
fully discharged.
Do not exit the vehicle before applying the park
brake and shifting the transmission to neutral
(N). Otherwise, the vehicle could roll, causing
property damage, personal injury, or loss of life.
16.1
Failure or improper selection or use of hoses,
tubing, fittings, assemblies, or related accesso-
ries can cause death, personal injury, and prop-
erty damage. Possible consequences of failure or
improper selection or use of these items include
but are not limited to the following:
•
Fittings thrown off at high speed.
•
High velocity fluid discharge.
•
Explosion or burning of the discharged fluid.
•
Contact with suddenly moving or falling objects
that are controlled by the discharged fluid.
•
Injection by high-pressure fluid discharge.
•
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.
NOTICE
When the red stop transmission indicator illumi-
nates, the transmission control module (TCM) or
hybrid control module (HCM) senses a malfunc-
tion in the hydraulic hybrid drive system and the
message center will display STOP TRANS and/or
STOP HYBRID. The vehicle will shut down imme-
diately, in order to avoid damaging the hydraulic
hybrid system.
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
(241 to 483 kPa). Operating the vehicle with a low
LPR fluid level will result in damage to the hy-
draulic hybrid system.
Remove the rear driveshaft before towing a ve-
hicle equipped with the hydraulic hybrid drive
system. Failure to do so will result in damage to
the hybrid drive system. Once the driveshaft has
been removed, do not attempt to start a vehicle
