Manual Transmission
The shift lever should be in NEUTRAL and the parking
brake engaged. Hold the clutch pedal to the floor
and start the engine. Your vehicle will not start if the
clutch pedal is not all the way down — that is a
safety feature.
1. With your foot off the accelerator pedal, turn your
ignition key to START. Then, let go of the key; the
engine will start automatically. The idle speed
will go down as your engine gets warm.
2. If your engine 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 turn the key
to START. If the vehicle starts briefly but then stops
again, do the same thing.
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.
Engine Coolant Heater
Your vehicle may be equipped with an engine
coolant heater.
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.
