Fuel Economy (ECON) Mode
The Fuel Economy (ECON) mode can improve the vehi-
cle’s overall fuel economy during normal driving condi-
tions. Push the “econ” switch in the center stack of the
instrument panel and a green light will indicate the ECON
mode is engaged.
When the Fuel Economy (ECON) Mode is enabled, the
vehicle control systems will change the following:
•The transmission will upshift sooner and downshift
later. •
The transmission will skip select gears during shifts to
allow the engine to operate at lower speeds.
• The torque converter clutch may engage at lower engine
speeds and remain on longer.
• The engine idle speed will be lower.
• The overall driving performance will be more conserva-
tive.
• Some ECON mode functions may be temporarily inhib-
ited based on temperature and other factors.
Six-Speed Automatic Transmission
The transmission gear position display (located in the
instrument cluster) indicates the transmission gear range.
You must press the brake pedal to move the gear selector
out of PARK (Refer to “Brake/Transmission Shift Interlock
System” in this section). To drive, move the gear selector
from PARK or NEUTRAL to the DRIVE position.
The electronically-controlled transmission provides a pre-
cise shift schedule. The transmission electronics are self-
calibrating; therefore, the first few shifts on a new vehicle
may be somewhat abrupt. This is a normal condition, and
precision shifts will develop within a few hundred miles
(kilometers).

STARTING AND OPERATING 247
WARNING!
Do not coast in NEUTRAL and never turn off the
ignition to coast down a hill. These are unsafe practices
that limit your response to changing traffic or road
conditions. You might lose control of the vehicle and
have a collision.
CAUTION!
Towing the vehicle, coasting, or driving for any other
reason with the transmission in NEUTRAL can cause
severe transmission damage. Refer to “Recreational
Towing” in “Starting And Operating” and “Towing A
Disabled Vehicle” in “What To Do In Emergencies” for
further information.
DRIVE (D)
This range should be used for most city and highway
driving. It provides the smoothest upshifts and downshifts,
and the best fuel economy. The transmission automatically
upshifts through all forward gears. The DRIVE position
provides optimum driving characteristics under all normal
operating conditions.When frequent transmission shifting occurs (such as when
operating the vehicle under heavy loading conditions, in
hilly terrain, traveling into strong head winds, or while
towing a heavy trailer), use the Electronic Range Select
(ERS) shift control (refer to
Electronic Range Select (ERS)
Operation in this section for further information) to select
a lower gear range. Under these conditions, using a lower
gear range will improve performance and extend transmis-
sion life by reducing excessive shifting and heat buildup.
During cold temperatures, transmission operation may be
modified depending on engine and transmission tempera-
ture as well as vehicle speed. This feature improves warm
up time of the engine and transmission to achieve maxi-
mum efficiency. Engagement of the torque converter clutch
is inhibited until the transmission fluid is warm (refer to
the “Note” under “Torque Converter Clutch” in this sec-
tion). During extremely cold temperatures (-16°F [-27°C] or
below), operation may briefly be limited to third gear only.
Normal operation will resume once the transmission tem-
perature has risen to a suitable level.

STARTING AND OPERATING 251
To exit ERS mode, simply hold the gear selector to the right
(+) until the gear limit display disappears from the instru-
ment cluster.WARNING!
Do not downshift for additional engine braking on a
slippery surface. The drive wheels could lose their grip
and the vehicle could skid, causing a collision or
personal injury.

NOTE: To select the proper gear position for maximum
deceleration (engine braking), tap the gear selector to the
left (-) repeatedly as the vehicle slows. The transmission
will shift to the range from which the vehicle can best be
slowed down.
Overdrive Operation
The automatic transmission includes an electronically con-
trolled Overdrive (sixth gear). The transmission will auto-
matically shift into Overdrive if the following conditions
are present:
• The gear selector is in the DRIVE position. •
The transmission fluid has reached an adequate tem-
perature.
• The engine coolant has reached an adequate tempera-
ture.
• The vehicle speed is sufficiently high.
• The driver is not heavily pressing the accelerator.Torque Converter Clutch
A feature designed to improve fuel economy has been
included in the automatic transmission on your vehicle. A
clutch within the torque converter engages automatically
at calibrated speeds. This may result in a slightly different

REFUELING THE VEHICLE
The gas cap is located behind the fuel filler door on the left
side of the vehicle. If the gas cap is lost or damaged, be sure
the replacement cap is for use with this vehicle.
NOTE:The driver’s side sliding door cannot be opened
while the fuel door is open. This feature operates only
when the sliding door is fully closed prior to opening the
fuel door.
CAUTION!
• Damage to the fuel system or emissions control
system could result from using an improper fuel
tank filler tube cap. A poorly fitting cap could let
impurities into the fuel system and may cause the
“Malfunction Indicator Light (MIL)” to turn on, due
to fuel vapors escaping from the system.
• To avoid fuel spillage and overfilling, do not “top
off” the fuel tank after filling.
WARNING!
• Never have any smoking materials lit in or near the
vehicle when the gas cap is removed or the tank is
being filled.
• Never add fuel when the engine is running. This is
in violation of most state and federal fire regulations
and may cause the MIL to turn on.
• A fire may result if gasoline is pumped into a
portable container that is inside of a vehicle. You
could be burned. Always place gas containers on the
ground while filling.
Fuel Filler Cap

STARTING AND OPERATING 267
NOTE:
•When the fuel nozzle “clicks” or shuts off, the fuel tank
is full.
• Tighten the fuel filler cap until you hear a “clicking”
sound. This is an indication that the fuel filler cap is
properly tightened.
• If the gas cap is not tightened properly, the MIL may
come on. Be sure the gas cap is tightened every time the
vehicle is refueled.
Loose Fuel Filler Cap Message
If the vehicle diagnostic system determines that the fuel
filler cap is loose, improperly installed, or damaged, a
”gASCAP” message will display in the odometer or a
“Check Gascap” message will display in the instrument
cluster. If this occurs, tighten the fuel filler cap properly
and press the Trip Odometer button to turn off the mes-
sage. If the problem continues, the message will appear the
next time the vehicle is started.
A loose, improperly installed, or damaged fuel filler cap
may also turn on the MIL.
VEHICLE LOADING
Certification Label
As required by National Highway Traffic Safety Adminis-
tration regulations, your vehicle has a certification label
affixed to the driver’s side door or pillar.
This label contains the month and year of manufacture,
Gross Vehicle Weight Rating (GVWR), Gross Axle Weight
Rating (GAWR) front and rear, and Vehicle Identification
Number (VIN). A Month-Day-Hour (MDH) number is
included on this label and indicates the Month, Day and
Hour of manufacture. The bar code that appears on the
bottom of the label is your VIN.
Gross Vehicle Weight Rating (GVWR)
The GVWR is the total permissible weight of your vehicle
including driver, passengers, vehicle, options and cargo.
The label also specifies maximum capacities of front and
rear axle systems (GAWR). Total load must be limited so
GVWR and front and rear GAWR are not exceeded.
Payload
The payload of a vehicle is defined as the allowable load
weight a truck can carry, including the weight of the driver,
all passengers, options and cargo.
268 STARTING AND OPERATING
Gross Axle Weight Rating (GAWR)
The GAWR is the maximum permissible load on the front
and rear axles. The load must be distributed in the cargo
area so that the GAWR of each axle is not exceeded.
Each axle GAWR is determined by the components in the
system with the lowest load carrying capacity (axle,
springs, tires or wheels). Heavier axles or suspension
components sometimes specified by purchasers for in-
creased durability does not necessarily increase the vehi-
cle’s GVWR.
Tire Size
The tire size on the Vehicle Certification Label represents
the actual tire size on your vehicle. Replacement tires must
be equal to the load capacity of this tire size.
Rim Size
This is the rim size that is appropriate for the tire size
listed.
Inflation Pressure
This is the cold tire inflation pressure for your vehicle for
all loading conditions up to full GAWR.
Curb Weight
The curb weight of a vehicle is defined as the total weight
of the vehicle with all fluids, including vehicle fuel, at full
capacity conditions, and with no occupants or cargo loaded
into the vehicle. The front and rear curb weight values are
determined by weighing your vehicle on a commercial
scale before any occupants or cargo are added.
Loading
The actual total weight and the weight of the front and rear
of your vehicle at the ground can best be determined by
weighing it when it is loaded and ready for operation.
The entire vehicle should first be weighed on a commercial
scale to insure that the GVWR has not been exceeded. The
weight on the front and rear of the vehicle should then be
determined separately to be sure that the load is properly
distributed over the front and rear axle. Weighing the
vehicle may show that the GAWR of either the front or rear
axles has been exceeded but the total load is within the
specified GVWR. If so, weight must be shifted from front to
rear or rear to front as appropriate until the specified
weight limitations are met. Store the heavier items down
low and be sure that the weight is distributed equally. Stow
all loose items securely before driving.6
STARTING AND OPERATING 269
Automatic Transmission
The DRIVE range can be selected when towing. However,
if frequent shifting occurs while in DRIVE, use the Elec-
tronic Range Select (ERS) shift control to manually select a
lower gear range.
NOTE:Using a lower gear range while operating the
vehicle under heavy loading conditions, will improve
performance and extend transmission life by reducing
excessive shifting and heat buildup. This action will also
provide better engine braking.
If you REGULARLY tow a trailer for more than 45 minutes
of continuous operation, then change the transmission
fluid and filter as specified for police, taxi, fleet, or
frequent trailer towing. Refer to the “Maintenance Plan”
for the proper maintenance intervals.
Electronic Range Select (ERS)
• When using the ERS shift control, select the highest gear
that allows for adequate performance and avoids fre-
quent downshifts. For example, choose “4” if the desired
speed can be maintained. Choose “3” or “2” if needed to
maintain the desired speed. •
To prevent excess heat generation, avoid continuous
driving at high RPM. Reduce vehicle speed as necessary
to avoid extended driving at high RPM. Return to a
higher gear range or vehicle speed when grade and road
conditions allow.
Speed Control — If Equipped
• Do not use on hilly terrain or with heavy loads.
• When using the speed control, if you experience speed
drops greater than 10 mph (16 km/h), disengage until
you can get back to cruising speed.
• Use speed control in flat terrain and with light loads to
maximize fuel efficiency.
Cooling System
To reduce potential for engine and transmission overheat-
ing, take the following actions:
City Driving
• In city traffic — while stopped, place the transmission in
NEUTRAL, but do not increase engine idle speed.
Highway Driving
• Reduce speed.
• Temporarily turn off air conditioning.
