If the engine will not start

If the engine will not start even though correct starting proce-
dures are being followed (→P. 195), consider each of the follow-
ing points.
The engine will not start even though the starter motor operates
normally.
One of the following may be the cause of the problem:
● There may not be sufficient fuel in the vehicle's tank.
Refuel the vehicle.
Flex-fuel vehicles: The type of fuel may be different. When refuel-
ing, add the same type of fuel, if available.
After adding a different type of fuel, the engine may run roughly and
driving performance may be reduced for a while when the engine is
first started. In this case, wait until the engine runs normally.
● The engine may be flooded.
Try to restart the engine again following correct starting procedures.
