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. See your dealer
before adding electrical
equipment.
This damage would not be
covered by your warranty.

Engine Starting

Make sure the park brake is
applied before starting the engine.
To start a vehicle with an automat-
ic transmission, the gear selector
must be in P (Park) or N (Neutral).
Use N (Neutral) to restart when
the vehicle is already moving.
NOTICE
Do not shift into P (Park) while
the vehicle is moving.
Otherwise, the transmission
could be damaged.
With a manual transmission, push
the clutch pedal to the floor and
put the transmission in neutral.
The engine won't start if the clutch
pedal is not all the way down.
