''Advisory for requirement 8.d., jumping off a vehicle.'' The electrical system of a hybrid vehicle can be substantially different from standard gasoline engines. When attempting to work on a hybrid, be sure to read the manual thoroughly before attempting to jump start it. Serious damage or injury can result if the proper steps are not followed. For all types of engines, the manual should always be read thoroughly and personal protection devices must be worn.
