When trouble arises
If your vehicle overheats
●The needle of the engine coolant temperature gauge ( P. 9 4 )
enters the red zone o r a loss of engine power is experienced.
(For example, the vehicle speed does not increase.)
● Steam comes out f rom under the hood.
Stop the vehicle in a safe place and turn off the air condition ing sys-
