{CAUTION:
Anyone who is up against, or very close
to, any airbag when it inates can be
seriously injured or killed. Airbags plus
lap-shoulder belts offer the best
protection for adults, but not for young
children and infants. Neither the vehicle’s
safety belt system nor its airbag system is
designed for them. Young children and
infants need the protection that a child
restraint system can provide. Always
secure children properly in your vehicle.
To read how, seeOlder Children on
page 56orInfants and Young Children on
page 59.There is an airbag
readiness light on the
instrument panel cluster,
which shows the
airbag symbol.
The system checks the airbag electrical system for
malfunctions. The light tells you if there is an
electrical problem. SeeAirbag Readiness Light on
page 234for more information.

{CAUTION:
It can be dangerous to drive with the
liftgate open because carbon monoxide
(CO) gas can come into your vehicle. You
cannot see or smell CO. It can cause
unconsciousness and even death. If you
must drive with the liftgate open or if
electrical wiring or other cable
connections must pass through the seal
between the body and the liftgate:
Make sure all other windows are shut.
Turn the fan on your heating or
cooling system to its highest speed
and select the control setting that will
force outside air into your vehicle. See
Climate Control System on page 217
orDual Climate Control System on
page 220.
If you have air outlets on or under the
instrument panel, open them all the
way. SeeEngine Exhaust on page 163.To close the liftgate, pull down on the handle, then
rmly shut the liftgate. Do not drive with the
liftgate open, even slightly.

When the PASS-Key®III system senses that
someone is using the wrong key, it shuts down the
vehicle’s starter and fuel systems. The starter will
not work and fuel will stop being delivered to the
engine. Anyone using a trial-and-error method to
start the vehicle will be discouraged because of the
high number of electrical key codes.
If the engine does not start and the security
message comes on, the key may have a damaged
transponder. Turn the ignition off and try again.
If the engine still does not start, and the key
appears to be undamaged, try another ignition
key. At this time, you may also want to check the
instrument panel PASS KEY fuse. If the engine
still does not start with the other key, your vehicle
needs service. If your vehicle does start, the
rst key may be faulty. See your dealer or
a locksmith who can service the PASS-Key
®III to
have a new key made. SeeFuses and Circuit
Breakers on page 527.
It is possible for the PASS-Key
®III decoder to
learn the transponder value of a new or
replacement key. Up to 10 keys may be
programmed for the vehicle. This procedure is for
learning additional keys only. If all the currently
programmed keys are lost or do not operate, youmust see your dealer or a locksmith who can
service PASS-Key
®III to have keys made
and programmed to the system.
See your dealer or a locksmith who can service
PASS-Key
®III to get a new key blank that is
cut exactly as the ignition key that operates the
system.
To program the new key, do the following:
1. Verify the new key has PK3 stamped on it.
2. Insert the original, already programmed
key into the ignition lock cylinder and start the
engine. If the engine will not start, see your
dealer for service.
3. After the engine has started, turn the key to
LOCK and remove the key.
4. Insert the key to be programmed and turn it to
RUN within 10 seconds of removing the
previous key.
5. The security message will turn off once the
key has been programmed. It may not be
apparent that the security message went on
due to how quickly the key is programmed.
6. Repeat Steps 1 through 4 if additional keys
are to be programmed.
149

Ignition Positions
The key can be turned to one of four positions
while in the ignition switch.
A (LOCK):This is the only position from which
you can remove the key. This position locks
your ignition and transaxle.
Notice:Using a tool to force the key from the
ignition switch could cause damage or
break the key. Use the correct key and turn thekey only with your hand. Make sure the key is
all the way in. If none of this works, then
your vehicle needs service.
B (ACCESSORY):This is the position in which
you can operate the electrical accessories, such as
the radio.
C (RUN):This is the position to which the switch
returns after the engine is started and the
ignition key is released. This is the position for
driving. Even while the engine is not running, RUN
can be used to operate your electrical accessories
and to display some instrument panel warning
lights.
The battery could be drained if you leave the key
in the ACCESSORY or RUN position with the
engine off. You may not be able to start your
vehicle if the battery is allowed to drain for
an extended period of time.
D (START):This position starts the engine. When
the engine starts, release the ignition key. The
switch will return to RUN for driving.

Your vehicle has a Computer-Controlled
Cranking System. This feature assists in
starting the engine and protects the electrical
system. If the ignition key is turned to the
START position, and then released when the
engine begins cranking, the engine will
continue cranking until the vehicle starts or
until it exceeds the maximum cranking
time allowed, approximately 15 seconds to
prevent cranking motor damage. To prevent
starter-motor gear damage, this system
also prevents cranking if the engine is already
running. The engine cranking can be
stopped by turning the ignition switch to the
ACCESSORY or LOCK position.
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 the engine does not start in 10 seconds,
push the accelerator pedal about one-quarter
of the way down while you turn the key to
START. Do this until the engine starts.
As soon as it does, let go of the key.
3. If your engine still will not start, or starts but
then stops, it could be ooded with too much
gasoline. Try pushing your accelerator
pedal all the way to the oor and holding it
there as you hold the key in START for
a maximum of 15 seconds. This clears the
extra gasoline from the engine. If the engine
still will not start, or starts briey but then
stops again, repeat Step 1 or 2, depending on
the temperature. When the engine starts,
release the key and the accelerator pedal.
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 do not, your engine might
not perform properly. Any resulting damage
would not be covered by your vehicle’s
warranty.

Engine Coolant Heater
Your vehicle may have an engine coolant heater.
In very cold weather, 0°F (−18°C) or colder,
the engine coolant heater can help. You will get
easier starting and better fuel economy during
engine warm-up. Usually, the coolant heater
should be plugged in a minimum of four hours
prior to starting your vehicle. At temperatures
above 32°F (0°C), use of the coolant heater is not
required. Your vehicle may also have an internal
thermostat in the plug end of the cord. This
will prevent operation of the engine coolant heater
when the temperature is at or above 0°F (−18°C)
as noted on the cord.
To Use the Engine Coolant Heater
1. Turn off the engine.
2. Open the hood and unwrap the electrical
cord. The electrical cord is located on the
driver’s side of the engine compartment.
3. Plug it into a normal, grounded 110-volt AC
outlet.
{CAUTION:
Plugging the cord into an ungrounded
outlet could cause an electrical shock.
Also, the wrong kind of extension cord
could overheat and cause a re. You
could be seriously injured. Plug the cord
into a properly grounded three-prong
110-volt AC outlet. If the cord will not
reach, use a heavy-duty three-prong
extension cord rated for at least 15 amps.
4. Before starting the engine, be sure to unplug
and store the cord as it was before to keep it
away from moving engine parts. If you do
not, it could be damaged.
How long should you keep the coolant heater
plugged in? The answer depends on the outside
temperature, the kind of oil you have, and
some other things. Instead of trying to list
everything here, we ask that you contact your
dealer in the area where you will be parking your
vehicle. The dealer can give you the best
advice for that particular area.

Cargo Lamp
The cargo lamp is located in the rear of your
vehicle, above the liftgate opening, and does not
have a switch. The cargo lamp will come on
each time you open a door, unless you turn on the
interior lamps override. SeeInterior Lamps
Control on page 207.
Electric Power Management
This vehicle has Electric Power Management
(EPM), an advanced control system. It estimates
the battery’s temperature and state of charge
and then adjusts the voltage for best performance
and extended life of the battery.
When the battery’s state of charge is low, the
voltage is raised slightly to quickly put the charge
back in. When the state of charge is high, the
voltage is lowered slightly to prevent overcharging.
If the vehicle has a voltmeter gage, you may
see the voltage move up or down. This is normal.
If there is a problem, an alert will be displayed.
The battery can be discharged at idle if the
electrical loads are very high. This is true for all
vehicles. This is because the generator (alternator)may not be spinning fast enough at idle to
produce all the power that is needed for very high
electrical loads.
A high electrical load occurs when several of the
following loads are on: headlamps, high beams,
fog lamps, rear window defogger, climate
control fan at high speed, heated seats, engine
cooling fans, trailer loads, and loads plugged into
accessory power outlets.
EPM works to prevent excessive discharge of the
battery. It does this by balancing the generator’s
output and the vehicle’s electrical needs. It
can increase engine idle speed to generate more
power, whenever needed. It can temporarily
reduce the power demands of some accessories.
Normally, these actions occur in steps or levels,
without being noticeable. In rare cases at the
highest levels of corrective action, this action may
be noticeable to the driver. If so, a Driver
Information Center (DIC) message might be
displayed, such as Battery Saver Active or Battery
Voltage Low. If this message is displayed, it is
recommended that the driver reduce the electrical
loads as much as possible.
