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 fuel injection system operates. Before adding
electrical equipment, check with your dealer.
If you don’t, your
engine might not perform properly.
If you ever have to have your vehicle towed, see the part of this
manual that tells how to do it without damaging your vehicle.
See “Towing Your Vehicle” in the Index.
To start your 5.7 Liter (Code K) or 7.4 Liter (Code N) V8 engine:
1. Without pushing the accelerator pedal, turn your ignition key t\
o “Start.”
When the engine starts, let go of the key. The idle speed will go down
as your engine gets warm.
NOTICE:
I
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 three seconds, push the accelerator pedal about one-quarter
of the
way down for 12 more seconds, or until it starts.
3. If your engine still won’t start (or starts but then stops), \
it could be
flooded with too much gasoline. Try this:
Wait
15 seconds to let the starter motor cool down. Then push your
accelerator pedal all the way to the floor. Hold it there. Then hold the
key in “Start” for no more than ten seconds. This
clears the extra
gasoline from the engine. If the engine still doesn’t start, wait another
15 seconds and do Step
3 again.
Hot Engine Restart (Vehicles With 5.7L LO5 Engine and Over 8500 lbs.
GVWR): If your engine is already hot and then stalls, turn your ignition
key to
OFF. Then, turn your key to RUN, and wait about 20 seconds
before you restart your engine.
When the engine starts, let go of the key and the accelerator pedal.
If your engine is already hot and then stalls, turn your ignition\
key to
OFF.
Then turn your key to “Run” and wait 20 seconds before you restart your
engine. When the engine starts, let go of the key and the accelerator pedal.

Driving Through Deep Standing Water
NOTICE:
If you drive too quickly through deep puddles or standing water,
water can come in through your engine’s air intake and badly
damage your engine.
If you can’t avoid deep puddles or standing
water, drive through them very slowly.
Driving Through Water (Diesel Engines)
NOTICE:
Never drive through standing water more than 8 inches deep if
your vehicle has a diesel engine. Also, don’t drive through any
standing water faster than
5 mph (8 km/h). If you do, water can
be drawn in through the
air intake, and this can severely
damage your engine.
Driving In Snow (Diesel Engines)
When driving in a heavy snowstorm or in swirling snow with a diesel
engine, snow can get into the
air intake system. If you keep driving in these
conditions the air cleaner may get plugged, causing black smoke and loss of
power. In an emergency,
if the air cleaner gets plugged with snow, you can
remove the air cleaner. Then, drive
to a place of safety as soon as possible
and put the air cleaner back on.
