NOTICE:
If your key seems stuck in OFF and you can't
turn it, be sure you are using the correct key; if
so, is it all the way in? 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.

things like the radio and the windshield wipers when the
engine is off. This position will allow you to turn off the
engine, but still turn the steering wheel. Use
ACCESSORY if you must have your vehicle in motion
while the engine is off (for example, if your vehicle is
being pushed or towed).C (ON): This is the position that the switch returns to
after you start your engine and release the key. The
switch stays in ON when the engine is running. But even
when the engine is not running, you can use ON to
operate your electrical power accessories, and to display
some instrument panel warning lights.
D (START): This position starts the engine. When the
engine starts, release the key. The ignition switch will
return to ON for normal driving.
If the engine is not running, ACCESSORY and ON are
positions that allow you to operate your electrical
accessories, such as the radio.

optional sunroof and the optional Electronic Level
Control (ELC) will continue to work up to 10 minutes

Running Your Engine While
You're Parked
It's better not to park with the engine running. But if you
ever have to, here are some things to know.
CAUTION:
Idling the engine with the climate control
system off could allow dangerous exhaust into
your vehicle. See the earlier Caution under
ªEngine Exhaust.º
Also, idling in a closed-in place can let deadly
carbon monoxide (CO) into your vehicle even
if the fan is at the highest setting. One place
this can happen is a garage. Exhaust
-- with
CO
-- can come in easily. NEVER park in a
garage with the engine running.
Another closed-in place can be a blizzard.
See ªBlizzardº in the Index.
CAUTION:
It can be dangerous to get out of your vehicle if
the shift lever is not fully in PARK (P) with the
parking brake firmly set. Your vehicle can roll.
Don't leave your vehicle when the engine is
running unless you have to. If you've left the
engine running, the vehicle can move suddenly.
You or others could be injured. To be sure your
vehicle won't move, even when you're on fairly
level ground, always set your parking brake and
move the shift lever to PARK (P).
Follow the proper steps to be sure your vehicle won't
move. See ªShifting Into PARK (P)º in the Index.
If you're pulling a trailer, see ªTowing a Trailerº in
the Index.
Horn

Be sure to continue scanning your displays, controls and
driving environment just as you would in a vehicle
without HUD. If you never look at your instrument
panel cluster, you may not see something important,
such as a warning light. Under important warning
conditions, the CHECK GAGES icon will illuminate in
the HUD. Glance at your instrument panel cluster for
more information.
NOTICE:
Although the HUD image appears to be near the
front of the vehicle, do not use it as a parking aid.
The HUD was not designed for that purpose. If
you try to use it as such, you may misjudge the
distance and damage your vehicle.
The HUD controls are
located to the left of the
steering wheel on the
instrument panel.
When the HUD is on, the speedometer reading will
always be displayed. The current radio station, cassette
tape or CD number and track number will only be
displayed for three seconds after the radio, tape or CD
track status changes. This will happen whenever one of
the radio controls is pressed, either on the radio or on
the audio steering wheel controls (if equipped).
