Electric Power Management
The vehicle has Electric Power Management (EPM)
that estimates the battery’s temperature and state
of charge. It 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
or a voltage display on the Driver Information Center
(DIC), 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 idlespeed 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 3-49.
Battery Run-Down Protection
Your vehicle has a battery saver feature designed to
protect the vehicle’s battery.
When any interior lamp is left on and the ignition is
turned off, the battery rundown protection system will
automatically turn the lamp off after 20 minutes. This
will avoid draining the battery. This vehicle also has a
retained accessory power feature. If the radio is on,
it will turn off after 10 minutes or if any door on the
vehicle is opened. SeeRetained Accessory Power (RAP)
on page 2-21.

Climate Controls
Climate Control System
The heating, cooling, and ventilation for the vehicle can
be controlled with this system. If your vehicle has the
remote start feature, the climate control system functions
as part of the remote start feature. SeeRemote
Keyless Entry (RKE) System Operation on page 2-5.
Operation
9
(Fan):Turn the left knob clockwise or
counterclockwise to increase or decrease the fan speed.
In any setting other than off, the fan runs continuously
with the ignition on. To turn off the air completely,
turn the fan to 0 and select the recirculation button.Temperature Control:Turn the center knob clockwise
or counterclockwise to increase or decrease the
temperature inside the vehicle.
Use the right knob to select from the following modes:
There is one position between each mode to nely
adjust airow position.
H(Vent):This mode directs air to the instrument
panel outlets.
)(Bi-Level):This mode splits the air between the
instrument panel outlets and the oor outlets.
6(Floor):This mode directs most of the air to the
oor outlets with some air directed to the windshield
and side windows.
The right knob may also be used to select the defrost
and defog modes that are described in this section.
You can also select modes by using the following buttons:
;(Outside Air):Press this button to turn the
outside air mode on. When this mode is on, outside air
will circulate throughout the vehicle. When the button
is pressed, an indicator light in the button comes on
to show that it is activated. The outside air mode can
be used with all modes, but it cannot be used with
the recirculation mode.
3-19

@(Recirculation):Press this button to recirculate
cabin air through the vehicle. It can be used to prevent
outside air and odors from entering the vehicle or to
help heat or cool the air inside the vehicle more quickly.
An indicator light will come on in this mode. Operation
in this mode during periods of high humidity and
cool outside temperatures may result in increased
window fogging. If window fogging is experienced,
select the defrost mode.
The recirculation mode cannot be used with oor,
defrost, or defogging modes. If you try to select
recirculation in one of those modes, the indicator
light ashes several times and turns off.
#(Air Conditioning):Press this button to turn the
air conditioning system on or off. When this button
is pressed, an indicator light on the button comes
on to show that the air conditioning is activated.
The air conditioning can be selected in any mode
as long as the fan switch is on.
The air conditioning compressor does not operate
when outside temperatures fall below 38°F (3°C).
The indicator light ashes several times and turns off
when outside conditions affect air conditioning operation.
This is normal.On hot days, open the windows to let hot inside air
escape; then close them. This helps to reduce the time
it takes for the vehicle to cool down. It also helps the
system to operate more efficiently.
For quick cool down on hot days, select the following
settings together:
1. Vent mode.
2. Outside air.
3. Air conditioning.
4. The coolest temperature.
5. The highest fan speed.
6. Once the vehicle’s interior temperature is below the
outside temperature, select recirculation mode for
enhanced cooling.
Using these settings together for long periods of time
may cause the air inside of the vehicle to become
too dry. To prevent this from happening, after the air
inside of the vehicle has cooled, turn the recirculation
mode off.
The air conditioning system removes moisture from the
air, so a small amount of water might drip underneath
the vehicle while idling or after turning off the engine.
This is normal.
((Heated Seats):If your vehicle has heated seats,
seeHeated Seats on page 1-4.

Before Leaving on a Long Trip
To prepare your vehicle for a long trip, consider having it
serviced by your dealer/retailer before departing.
Things to check on your own include:
Windshield Washer Fluid:Reservoir full? Windows
clean — inside and outside?
Wiper Blades:In good shape?
Fuel, Engine Oil, Other Fluids:All levels checked?
Lamps:Do they all work and are lenses clean?
Tires:Are treads good? Are tires inated to
recommended pressure?
Weather and Maps:Safe to travel? Have
up-to-date maps?
Highway Hypnosis
Always be alert and pay attention to your surroundings
while driving. If you become tired or sleepy, nd a safe
place to park your vehicle and rest.
Other driving tips include:
Keep the vehicle well ventilated.
Keep interior temperature cool.
Keep your eyes moving — scan the road ahead
and to the sides.
Check the rearview mirror and vehicle instruments
often.
Hill and Mountain Roads
Driving on steep hills or through mountains is different
than driving on at or rolling terrain. Tips for driving
in these conditions include:
Keep your vehicle serviced and in good shape.
Check all uid levels and brakes, tires, cooling
system, and transmission.
Going down steep or long hills, shift to a
lower gear.
{CAUTION:
If you do not shift down, the brakes could get
so hot that they would not work well. You
would then have poor braking or even none
going down a hill. You could crash. Shift down
to let the engine assist the brakes on a steep
downhill slope.
4-16

Driving with a Trailer
{CAUTION:
If you have the liftgate open and you pull a
trailer with your vehicle, carbon monoxide (CO)
could come into your vehicle. You cannot see
or smell CO. It can cause unconsciousness or
death. SeeEngine Exhaust on page 2-35.To
maximize your safety when towing a trailer:
Have your exhaust system inspected for
leaks, and make necessary repairs before
starting on your trip.
Keep the liftgate closed.
If exhaust does come into your vehicle
through a window in the rear or another
opening, drive with your front, main
heating or cooling system on and with the
fan on any speed. This will bring fresh,
outside air into your vehicle. Do not use
the climate control setting for maximum air
because it only recirculates the air inside
your vehicle. SeeClimate Control System
on page 3-19.Towing a trailer requires a certain amount of experience.
Before setting out for the open road, you will want to
get to know your rig. Acquaint yourself with the feel of
handling and braking with the added weight of the trailer.
And always keep in mind that the vehicle you are
driving is now a good deal longer and not nearly as
responsive as your vehicle is by itself.
Before you start, check all trailer hitch parts and
attachments, safety chains, electrical connector, lamps,
tires and mirror adjustment. If the trailer has electric
brakes, start your vehicle and trailer moving and then
apply the trailer brake controller by hand to be sure the
brakes are working. This lets you check your electrical
connection at the same time.
During your trip, check occasionally to be sure that the
load is secure, and that the lamps and any trailer brakes
are still working.
4-37

Parking on Hills
{CAUTION:
You really should not park your vehicle, with a
trailer attached, on a hill. If something goes
wrong, your rig could start to move. People
can be injured, and both your vehicle and the
trailer can be damaged.
But if you ever have to park your rig on a hill, do the
following:
1. Apply your regular brakes, but do not shift into
PARK (P) yet.
2. Have someone place chocks under the trailer
wheels.
3. When the wheel chocks are in place, release the
regular brakes until the chocks absorb the load.
4. Reapply the regular brakes. Then apply your
parking brake, and then shift to PARK (P).
5. Release the regular brakes.
When You Are Ready to Leave After
Parking on a Hill
1. Apply your regular brakes and hold the pedal down
while you do the following:
Start your engine.
Shift into a gear.
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 are
pulling a trailer. See the Maintenance Schedule for
more on this. Things that are especially important in
trailer operation are automatic transmission uid, engine
oil, 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 are trailering, it is a good
idea to review these sections before you start your trip.
Check periodically to see that all hitch nuts and bolts
are tight.

Checking Engine Oil
It is a good idea to check the engine oil every time you
get fuel. In order to get an accurate reading, the oil
must be warm and the vehicle must be on level ground.
The engine oil dipstick handle is a yellow loop. See
Engine Compartment Overview on page 5-12for
the location of the engine oil dipstick.
1. Turn off the engine and give the oil several minutes
to drain back into the oil pan. If you do not do this,
the oil dipstick might not show the actual level.
2. Pull out the dipstick and clean it with a paper towel
or cloth, then push it back in all the way. Remove it
again, keeping the tip down, and check the level.
5-15

Engine Coolant
The cooling system in your vehicle is lled with
DEX-COOL®engine coolant. This coolant is designed
to remain in your vehicle for ve years or 150,000 miles
(240 000 km), whichever occurs rst, if you add only
DEX-COOL
®extended life coolant.
The following explains your cooling system and how to
add coolant when it is low. If you have a problem with
engine overheating, seeEngine Overheating
on page 5-24.
A 50/50 mixture of clean, drinkable water and
DEX-COOL
®coolant will:
Give freezing protection down to−34°F (−37°C).
Give boiling protection up to 265°F (129°C).
Protect against rust and corrosion.
Help keep the proper engine temperature.
Let the warning lights and gages work as they
should.
Notice:Using coolant other than DEX-COOL
®may
cause premature engine, heater core, or radiator
corrosion. In addition, the engine coolant may
require changing sooner, at the rst maintenance
service after each 30,000 miles (50 000 km) or
24 months, whichever occurs rst. Any repairs would
not be covered by your warranty. Always use
DEX-COOL
®(silicate-free) coolant in your vehicle.
What to Use
Use a mixture of one-half clean, drinkable water and
one-half DEX-COOL®coolant which will not damage
aluminum parts. If you use this coolant mixture, you do
not need to add anything else.
{CAUTION:
Adding only plain water to the cooling system
can be dangerous. Plain water, or some other
liquid such as alcohol, can boil before the
proper coolant mixture will. The vehicle’s
coolant warning system is set for the proper
coolant mixture. With plain water or the wrong
mixture, the engine could get too hot but you
would not get the overheat warning. The
engine could catch re and you or others could
be burned. Use a 50/50 mixture of clean,
drinkable water and DEX-COOL
®coolant.
Notice:If you use an improper coolant mixture, your
engine could overheat and be badly damaged. The
repair cost would not be covered by your warranty.
Too much water in the mixture can freeze and crack
the engine, radiator, heater core, and other parts.
5-22

If you have to add coolant more than four times a year,
have your dealer/retailer check your cooling system.
Notice:If you use extra inhibitors and/or additives
in your vehicle’s cooling system, you could damage
your vehicle. Use only the proper mixture of the
engine coolant listed in this manual for the cooling
system. SeeRecommended Fluids and Lubricants on
page 6-12for more information.
Checking Coolant
The surge tank is located on the driver’s side of the
engine compartment. SeeEngine Compartment
Overview on page 5-12for more information on location.
{CAUTION:
Turning the surge tank pressure cap when the
engine and radiator are hot can allow steam
and scalding liquids to blow out and burn you
badly. Never turn the surge tank pressure
cap — even a little — when the engine and
radiator are hot.
The vehicle must be on a level surface. When your
engine is cold, the coolant level should be at the COLD
FILL line. When your engine is warm, the level should
be at the COLD FILL line or a little higher.
