Checking the circuit breaker Type A fuses can be pulled out by the pullout tool. If you are not sure whether the fuse has blown, try replacing the suspected fuse with one that you know is good. If the fuse has blown, push a new fuse into the clip. Only install a fuse with the amperage rating designated on the fuse box lid. If you do not have a spare fuse, in an emergency you can pull out the "CIG", "RADIO", "DOME" or "A/C" fuse, which may be dispensable for normal driving, and use it if its amperage rating is the same. If you cannot use one of the same amperage, use one that is lower, but as close as possible to the rating. If the amperage is lower than that specified, the fuse might blow out again but this does not indicate anything wrong. Be sure to get the correct fuse as soon as possible and return the substitute to its original clip. It is a good idea to purchase a set of spare fuses and keep them in your vehicle for emergencies. If the new fuse immediately blows out, there is a problem with the electrical system. Have your Toyota dealer correct it as soon as possible. In the event that the environmental control system or air conditioning system does not operate, check the circuit breaker (C.B). See "Fuse and circuit breaker locations" in Chapter 7-1 for a location of the circuit breaker. To reset the circuit breaker, first turn the ignition switch off and carefully insert a thin object, such as a toothpick, needle or safety pin, into the hole in the ciructi breaker until you hear a click. The component should now operate. This may be done without removing the cirucit breakers. If the cirucit breaker immediately goes off again or the component does not operate, turn off the component switch and have the electrical system checked by your Toyota dealer as soon as possible. See part 8 for then ame of the components affected by circuit breaker. ! CAUTION Never use a fuse with a higher amperage rating, or any other object, in place of a fuse. This may cause extensive damage and possibly a fire. 208
