Liftgate Caution
CAUTION:
It can be dangerous to drive with the liftgate
glass, liftgate or rear doors open because carbon
monoxide (CO) gas can come into your vehicle.
You can't see or smell CO. It can cause
unconsciousness and even death.
If you must drive with the liftgate glass, liftgate
or rear doors open or if electrical wiring or
other cable connections must pass through the
seal between the body and the liftgate glass,
liftgate or rear doors:

Make sure all other windows are shut.

Turn the fan on your heating or cooling
system to its highest speed with the setting
on VENT or OUTSIDE AIR. That will
force outside air into your vehicle.
See ªComfort Controlsº in the Index.

If you have air outlets on or under the
instrument panel, open them all the way.
See ªEngine Exhaustº in the Index.
Liftgate Glass and Liftgate
To open a mechanical lock system from the outside,
insert the key into the lock and turn it counterclockwise
to unlock the glass and liftgate.
The liftgate glass can be opened using the pushbutton on
the liftgate after the doors have been unlocked. This can
be done by using either the power door locks or the
remote keyless entry system.
To open the entire liftgate, lift the handle located in the
center of the door.
To lock a power lock system from the outside, insert the
key into the lock button and turn clockwise. All doors will
lock. You may also use the keyless entry system or the
power door locks to lock the liftgate and liftgate glass.
Panel Doors
To open the rear panel doors, you must open the
passenger's side panel door first. If the door is locked,
insert your door key in the lock and turn it
counterclockwise to unlock it.
To open the passenger's side panel door, pull on the
handle and pull the door open.

2-13
To open the driver's side panel door, first open the
passenger's side door. Then, pull the handle on the left
door edge out and pull the door open.
To close the doors, close the driver's side door first.
After securely closing the door, close the passenger's
side door. Make sure both doors are latched securely.
To lock the rear doors from outside the vehicle, put your
key in the lock and turn it clockwise. If you have power
door locks, you can lock the side doors as well as the rear
doors from inside the vehicle. For more information, see
ªPower Door Locksº earlier in this section.
Theft
Vehicle theft is big business, especially in some cities.
Although your vehicle has a number of theft
-deterrent
features, we know that nothing we put on it can make it
impossible to steal. However, there are ways you can help.
Key in the Ignition
If you leave your vehicle with the keys inside, it's an
easy target for joy riders or professional thieves
-- so
don't do it.
When you park your vehicle and open the driver's door,
you'll hear a chime reminding you to remove your key
from the ignition and take it with you. Always do this.Your ignition and transmission will be locked.
Also remember to lock the doors.
If the key is in the ignition, with any door open, and you
try to lock your doors with the power door locks, the
driver's door will not stay locked. This will help to keep
you from locking your keys in the vehicle.
Parking at Night
Park in a lighted spot, close all windows and lock your
vehicle. Remember to keep your valuables out of sight.
Put them in a storage area, or take them with you.
Parking Lots
Even if you park in a lot where someone will be
watching your vehicle, it's still best to lock it up and
take your keys. But what if you have to leave your
ignition key? What if you have to leave something
valuable in your vehicle?

Put your valuables in a storage area, like your
glove box.

Valuables can be locked in the center floor console.

If your vehicle has a remote keyless entry system,
take the transmitter with you.

Lock all the doors except the driver's.

2-43
Exterior Lamps
Your parking lamp and headlamp switch is located on
the driver's side of your instrument panel.
Turn the knob clockwise to the parking lamps symbol to
manually turn on:

Parking Lamps

Sidemarker Lamps

Taillamps
License Plate Lamps

Instrument Panel Lights

Roof Marker Lamps (If Equipped)
Turn the knob clockwise to the master lamps symbol to
turn on all the lamps listed as well as the headlamps.
Turn the knob all the way counterclockwise to turn
off your lamps and put the system into automatic
headlamp mode.
Turn the thumbwheel next to the knob up to adjust
instrument panel lights. Turn the thumbwheel up to
return the radio and gearshift indicator LED display to
full intensity when the headlamps or parking lamps
are on. To turn on the dome lamps, with the vehicle
doors closed, turn the thumbwheel up to the second
notch position.
You can switch your headlamps from high to low-beam
by pulling on the turn signal/high
-beam lever.
A circuit breaker protects your headlamps. If you have
an electrical overload, your headlamps will flicker on
and off. Have your headlamp wiring checked right away
if this happens.
