Automatic Transmission

Move your shift lever to PARK (P) or NEUTRAL (N). Your engine won't start in any other position - that's a safety feature. To restart when you're already moving, use NEUTRAL (N) only.

Notice: Do not try to shift to P (Park) if the vehicle is moving. If you do, you could damage the transmission. Shift to P (Park) only when the vehicle is stopped.

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 won't start if the clutch pedal is not all the way down - that's a safety feature.

Starting Your Engine

  1. With your foot off the accelerator pedal and the parking brake firmly applied, turn your ignition key to START. When the engine starts, let go of the key. The idle speed will go down as your engine gets warm.
  2. Notice: Holding the key in START for longer than 15 seconds at a time will cause the battery to be drained much sooner. And the excessive heat can damage the starter motor. Wait about 15 seconds between each try to help avoid draining the battery or damaging the starter.

  3. If it doesn't start, wait about 15 seconds and try again to start the engine by turning the ignition key to START. Wait about 15 seconds between each try.
  4. When your engine has run about 10 seconds to warm up, your vehicle is ready to be driven. Don't run your engine at high speeds when it is cold.

    If the weather is below freezing (32°F or 0°C), let the engine run for a few minutes to warm up.

Notice: The engine is designed to work with the electronics in the vehicle. If electrical parts or accessories are added, 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.

Racing or Other Competitive Driving

See your warranty book before using your vehicle for racing or other competitive driving.

Notice: If you use your vehicle for racing or other competitive driving, the engine may use more oil than it would with normal use. Low oil levels can damage the engine. Be sure to check the oil level often during racing or other competitive driving and keep the level at or near 1 quart (1 L) above the upper mark that shows the proper operating range on the engine oil dipstick. For information on how to add oil, see Engine Oil . After the competitive driving, remove excess oil so that the level on the dipstick is not above the upper mark that shows the proper operating range.
