When starting your engine in very cold weather (below

0 F or

-18 C), do this:

1. With your foot off the accelerator pedal, turn the

ignition key to START and hold it there up to

15 seconds. When the engine starts, let go of the key.

2. If your engine still won’t 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. When the engine

starts, let go of the key and accelerator. 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 don’t,

your engine might not perform properly.

Engine Coolant Heater (If Equipped)

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.
