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 a maximum of
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 transaxle gently
until the oil warms up and lubricates all
moving parts.
Notice: Your engine is designed to work with
the electronics in your vehicle. If you add
electrical parts or accessories, you could
change the way the engine operates. Before
adding electrical equipment, check with
your dealer. If you do not, your engine might
not perform properly. Any resulting damage
would not be covered by your vehicle’s
warranty.
Engine Coolant Heater
If your vehicle has this feature, in very cold weather,
0°F (
−
18°C) or colder, the engine coolant heater
can help. You’ll get easier starting and better fuel
economy during engine warm-up. Usually, the
coolant heater should be plugged in a minimum
of four hours prior to starting your vehicle.
At temperatures above 32°F (0°C), use of the
coolant heater is not required.
