LOCK
(B):
This position locks your ignition, steering
wheel and transmission.
It's a
theft-deterrent feature.
You
will only
be
able to remove your key when the
ignition is turned
to
LOCK.
OFF (C):
This position lets you turn off the engine but
still turn the steering wheel. It doesn't lock the steering
wheel like LOCK. Use OFF if you must have your
vehicle in motion while the engine is off (for example, if
your vehicle is being pushed).
RUN (D): This is the position for driving.
START (E): This starts your engine.
NOTICE:
If
your key seems stuck in LOCK and you can't
turn it, be sure you are using the correct key; if
so, is it all the way in? If it is, then turn the
steering wheel left and right while you turn the
key hard. But turn the key only with your hand.
Using a tool to force it could break the key or the
ignition switch. If none of this works, then your
vehicle needs service.
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 warm.
