3. If the engine still will not start, or starts but
then stops, it could be flooded with too much
gasoline. Try pushing your accelerator pedal all
the way to the floor and holding it there as you
hold the key in START for about three seconds.
If the vehicle starts briefly but then stops again,
do the same thing, but this time keep the pedal
down for five or six seconds. This clears the
extra gasoline from the engine.
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
Your vehicle may have an engine coolant heater.
In very cold weather, 0°F (18°C) or colder, the
engine coolant heater can help. You will 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.
To Use the Engine Coolant Heater
1. Turn off the engine.
2. Open the hood and unwrap the electrical
cord. The cord is located on the driver’s
side of the engine compartment, near
the battery.
3. Plug it into a normal, grounded 110-Volt AC
outlet.
