2. If the engine does not start after 5-10 seconds,

especially in very cold weather (below 0°F or

18°C),

it could be flooded with too much gasoline. Try
pushing the accelerator pedal all the way to the floor
and holding it there as you hold the key in START for
up to 15 seconds. Wait at least 15 seconds between
each try, to allow the cranking motor to cool down.
When the engine starts, let go of the key and
accelerator. If the vehicle starts briefly but then stops
again, do the same thing. This clears the extra
gasoline from the engine. Do not race the engine
immediately after starting it. Operate the engine and
transmission gently until the oil warms up and
lubricates all moving parts.

Notice: The engine is designed to work with the
electronics in the vehicle. If you add electrical parts
or accessories, you could change the way the
engine operates. Before adding electrical equipment,
check with your dealer/retailer. If you do not, the
engine might not perform properly. Any resulting
damage would not be covered by the vehicle
warranty.
