Starting Your Gasoline Engine - GMC Yukon Owner's Manual

Starting Your Gasoline Engine
If you have a diesel engine, see "Starting Your Diesel
Engine" in the, Diesel Engine Supplement.,
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:
Don't try to shift to PARK (P) if your vehicle is
moving. If you do, you could damage the
transmission. Shift to PARK (P) only when your
vehicle is stopped.
1. Without pushing the accelerator pedal, 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
warrn.
NOTICE:
Holding your key in START for longer than
15
seconds at a time will cause your battery to
be drained much sooner. And the excessive heat
can damage your starter motor.
2. If it doesn't start right away, hold your key in
START. If it doesn't start in 10 seconds, push the
accelerator pedal all the way down for five more
seconds,
or until it starts.
