Tribute 4WD L4-2.3L Hybrid (2008)
WARNING: The nominal high voltage traction battery (HVTB) voltage is 330 volts DC. The buffer zone must be set up and insulated rubber gloves
and a face shield must be worn. Failure to follow these instructions may result in severe personal injury or death.
WARNING: The high voltage traction battery (HVTB) and charging system contains high voltage components and wiring. High voltage cables and
wiring are orange in color. High voltage insulated safety gloves and a face shield must be worn when carrying out any diagnostics on this vehicle. Failure
to follow these instructions may result in severe personal injury or death.
WARNING: Before carrying out any removal and installation procedures of the high voltage traction battery (HVTB) system, the HVTB must be
depowered. Failure to follow these instructions may result in severe personal injury or death.
WARNING: The rubber insulating gloves that are to be worn while working on the high voltage system should be of the appropriate safety and
protection rating for use on the high voltage system. They must be inspected before use and must always be worn in conjunction with the leather outer
glove. Any hole in the rubber insulating glove is a potential entry point for high voltage. Failure to follow these instructions may result in severe personal
injury or death.
WARNING: High voltage insulated safety gloves and a face shield must be worn when working with high voltage cables. The ignition switch must be
OFF for a minimum of 5 minutes before removing high voltage cables. Failure to follow these instructions may result in severe personal injury or death.
WARNING: The buffer zone is required only when working with the high voltage system. Failure to follow these instructions may result in severe
personal injury or death.
