3. Slide the new battery into the transmitter with
the positive side of the battery facing down.
Use a type CR2032 battery, or equivalent
type. Make sure the cover is on tightly,
so water will not get in.
4. Snap the front and the back of the transmitter
together.
5. Test the operation of the transmitter with the
vehicle.
Remote Vehicle Start
Your vehicle may have a remote starting feature.
This feature allows you to start the engine
from outside of the vehicle.
If your vehicle has an outside temperature display,
during remote start this feature allows the
climate control system to default to a heating
mode during colder outside temperatures and a
cooling mode during warmer outside temperatures.
If your vehicle does not have an outside
temperature display, during remote start the
climate control system will turn on at the setting
the vehicle was set to when the vehicle was
last turned off.Laws in some communities may restrict the use of
remote starters. For example, requiring a person
using remote start to have the vehicle in view
when doing so. Check local regulations for
any requirements on remote starting of vehicles.
Do not use the remote start feature if your vehicle
is low on fuel. Your vehicle may run out of fuel.
Your remote keyless entry transmitter, with
the remote start button, provides an increased
range of operation. However, the range may
be less while the vehicle is running. As a result,
you may need to be closer to your vehicle to turn it
off, than you were to turn it on.
There are other conditions which can affect the
performance of the transmitter, seeRemote
Keyless Entry (RKE) System on page 90for
additional information.

Trunk
{CAUTION:
It can be dangerous to drive with the
trunk lid 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 trunk lid open or if
CAUTION: (Continued)
CAUTION: (Continued)
electrical wiring or other cable
connections must pass through the seal
between the body and the trunk lid:
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.
If you have air outlets on or under
the instrument panel, open them all
the way.
SeeEngine Exhaust on page 124.

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
Service Battery Charging System.If this message is displayed, it is recommended
that the driver reduce the electrical loads as much
as possible. SeeDIC Warnings and Messages
on page 199.
Battery Run-Down Protection
This vehicle has a feature to help prevent the
battery from being drained, if the interior courtesy
lamps, reading/map lamps, visor vanity lamps
or trunk lamp are accidentally left on. If any
of these lamps are left on, they will automatically
turn off after 10 minutes, if the ignition is off.
The lamps will not come back on again until
one of the following occurs:
The ignition is turned on.
The exterior lamps control is turned off, then
on again.
The headlamps will timeout after 10 minutes, if they
are manually turned on before the ignition is off.

Ashtray(s) and Cigarette Lighter
Your vehicle may have an ashtray and a cigarette
lighter. The ashtray and cigarette lighter may
be located in the console, if your vehicle has one,
otherwise, they may be located in the center
armrest of the front seat.
Notice:If you put papers, pins, or other
ammable items in the ashtray, hot cigarettes
or other smoking materials could ignite
them and possibly damage your vehicle.
Never put ammable items in the ashtray.
Notice:Holding a cigarette lighter in while
it is heating does not let the lighter back away
from the heating element when it is hot.
Damage from overheating can occur to the
lighter or heating element, or a fuse could be
blown. Do not hold a cigarette lighter in while it
is heating.
To use the lighter, just push it in all the way and
let go. When it’s ready, it will pop back out by itself.
Climate Controls
Climate Control System
This vehicle may have a dual or single climate
control system. With this system you can control
the heating, cooling, defrost, defog and
ventilation for the vehicle. If this vehicle has
heated seats, seeHeated Seats on page 10.
Dual Zone with Optional Heated Seat Controls
168

:(Outside Air):Press this button to turn on
outside air. When this mode is on, outside air
will circulate throughout your vehicle. When the
button is pressed, an indicator light will come on to
show that it is on.
?(Recirculation):Press this button to turn
on the recirculation mode. When the button
is pressed, an indicator light will come on to show
that it is on.
This mode keeps outside air from entering the
vehicle. It can be used to prevent outside air and
odors from entering your vehicle. Recirculation
may also help heat or cool the air inside your
vehicle more quickly once the temperature inside
the vehicle is equal to or better than the outside
temperature. The recirculation mode cannot
be used with outside air, oor, defrost, or
defogging modes.
Temperature Control:Turn the thumbwheels up
or down to increase or decrease the temperature
on the driver’s side or the passenger side of
the vehicle for the dual zone system. Turn the
center knob clockwise or counterclockwise
to increase or decrease the temperature for the
single zone system.
#(Air Conditioning):Press this button to turn
the air conditioning system on or off. When
A/C is pressed, an indicator light will come on to
let you know that the air conditioning is on.
On hot days, open the windows to let hot inside
air escape; then close them. This helps to reduce
the time it takes for your vehicle to cool down.
It also helps the system to operate more efficiently.
For quick cool down on hot days, do the
following:
1. Select the vent mode.
2. Select A/C.
3. Select the coolest temperature for both zones.
4. Select the highest fan speeds.
5. When the coolest temperature is selected in
the A/C mode, the system will automatically
go into the recirculation mode to improve
cooling. Press the Outside Air or Recirculation
button to turn off the automatic recirculation.
This feature will stay off until the climate
control system is powered on again or the
vehicle has been turned off and on again.

Highway Hypnosis
Is there actually such a condition as highway
hypnosis? Or is it just plain falling asleep at the
wheel? Call it highway hypnosis, lack of
awareness, or whatever.
There is something about an easy stretch of road
with the same scenery, along with the hum of the
tires on the road, the drone of the engine, and the
rush of the wind against the vehicle that can make
you sleepy. Do not let it happen to you! If it does,
your vehicle can leave the road in less than a
second, and you could crash and be injured.
What can you do about highway hypnosis?
First, be aware that it can happen.
Then here are some tips:
Make sure your vehicle is well ventilated, with
a comfortably cool interior.
Keep your eyes moving. Scan the road ahead
and to the sides. Check your rearview mirrors
and your instruments frequently.
If you get sleepy, pull off the road into a rest,
service, or parking area and take a nap, get
some exercise, or both. For safety, treat
drowsiness on the highway as an emergency.
Hill and Mountain Roads
Driving on steep hills or mountains is different
from driving in at or rolling terrain.
If you drive regularly in steep country, or if you are
planning to visit there, here are some tips that
can make your trips safer and more enjoyable.
Keep your vehicle in good shape. Check
all uid levels and also the brakes, tires,
cooling system, and transaxle. These parts
can work hard on mountain roads.
270

When You Are Ready to Leave After
Parking on a Hill
1. Apply your regular brakes and hold the pedal
down while you:
start your engine,
shift into a gear, and
release the parking brake.
2. Let up on the brake pedal.
3. Drive slowly until the trailer is clear of
the chocks.
4. Stop and have someone pick up and store
the chocks.
Maintenance When Trailer Towing
Your vehicle will need service more often when
you’re pulling a trailer. See the Maintenance
Schedule for more on this. Things that are
especially important in trailer operation are
automatic transmission uid (don’t overll),
engine oil, drive belts, cooling system and brake
system. Each of these is covered in this manual,
and the Index will help you nd them quickly.
If you’re trailering, it’s a good idea to review
this information before you start your trip.
Check periodically to see that all hitch nuts and
bolts are tight.
Engine Cooling When Trailer Towing
Your cooling system may temporarily overheat
during severe operating conditions. SeeEngine
Overheating on page 323.
