Starting
Your
Engine
Automatic Transaxle
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.
I
NOTICE:
Don't try to shift to PARK (P) if your Chevrolet
is moving. If you do, you could damage the
transaxle. Shift to PARK (P) only when your
vehicle is stopped.
Manual Transaxle
The gear selector should be in NEUTRAL (N). 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.
