Running the Vehicle While Parked
It is better not to park with the engine running. But if you
ever have to, here are some things to know.
{CAUTION:
Idling a vehicle in an enclosed area with poor
ventilation is dangerous. Engine exhaust may
enter the vehicle. Engine exhaust contains Carbon
Monoxide (CO) which cannot be seen or smelled.
It can cause unconsciousness and even death.
Never run the engine in an enclosed area that has
no fresh air ventilation. For more information, see
Engine ExhaustEngine Exhaust on page 2-30.
{CAUTION:
It can be dangerous to get out of the vehicle if the
automatic transmission shift lever is not fully in
P (Park) with the parking brake firmly set. The
vehicle can roll. Do not leave the vehicle when the
engine is running unless you have to. If you have
left the engine running, the vehicle can move
suddenly. You or others could be injured. To be
sure the vehicle will not move, even when you are
on fairly level ground, always set the parking
brake and move the shift lever to P (Park).
Follow the proper steps to be sure the vehicle will not
move. SeeShifting Into Park on page 2-27.
If parking on a hill and pulling a trailer, seeTowing a
Trailer on page 4-26.

Mirrors
Manual Rearview Mirror
Hold the inside rearview mirror in the center to move it for
a clearer view behind your vehicle. Adjust the mirror to
avoid glare from the headlamps behind. Push the tab
forward for daytime use and pull it for nighttime use.
If you have a cargo van without the rear door glass, the
vehicle may not have an inside rearview mirror.
Outside Manual Mirrors
Adjust the mirrors by pressing the mirror up and down
and left and right so you can see a little of the side of your
vehicle, and have a clear view of objects behind you.
The mirrors can be manually folded in or out.
On the lower portion of each mirror is an auxiliary
convex mirror. A convex mirror’s surface is curved so
you can see more from the driver seat. The auxiliary
convex mirrors can be adjusted manually by pressing
the mirror.
Outside Towing Mirrors
Vehicles with towing
mirrors can be adjusted
manually for a clear view of
the objects behind you.
On the lower portion of each mirror there is an auxiliary
convex mirror that can be adjusted manually to
provide an extended field of view.
The mirrors can be manually folded in or out.
