Starting Your 3400 V6 Engine
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 warm.
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. Wait about 
15 seconds between each try to help avoid
draining your battery or damaging your starter.
2. If it doesn’t start right away, hold your key in START.
If it doesn’t start in three seconds (or starts but then
stops), 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.
This clears the extra gasoline from the engine. When
the engine starts, let go of the key and the accelerator
pedal. If the engine still doesn’t start, wait another 
15 seconds and repeat this step.
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. 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.
