STARTING A GASOLINE ENGINE
When you start the engine, the idle speed increases, this helps to warm
up the engine. If the engine idle speed does not slow down automatically,
have your vehicle checked by an authorized dealer.
Before starting the engine:
• Make sure all occupants have fastened their safety belts.
• Make sure the headlamps and electrical accessories are off.
• Make sure the parking brake is on.
• Move the transmission selector lever to position P.
• Turn the ignition key to the on position.
