Starting the Engine, Automatic Transmission Check Starting System Message If this message is on, the ignition switch has to be held in the START (III) position manually until the engine starts. The ignition switch can be held in that position up to 15 seconds. Even though you may be able to start the engine manually without the auto control mode of the starting system, have your dealer inspect your vehicle. If there is a problem with the starting system, you will see a ''CHECK STARTING SYSTEM'' message on the multi-information display when the ignition switch is turned to the ON (II) position. You will also see this message when the auto control mode of the starting system has a problem. These indicators on the instrument panel show which position the shift lever is in. The ''D'' indicator comes on for a few seconds when you turn the ignition switch to the ON (II) position. If it flashes while driving (in any shift position), it indicates a possible problem in the transmission. Shift Lever Position Indicators Driving CONTINUED 443
