•Driving on slick surfaces.
•Cornering while towing a heavily loaded trailer (refer toTrailer
towingin theTires, Wheels and Loadingchapter.)
Roll Stability Control(RSC)
The RSC system works in conjunction with the AdvanceTracsystem to
help maintain roll stability of the vehicle during aggressive maneuvers by
applying brake force to one or more wheels.
During Roll Stability Control(RSC) events the “sliding car” icon in the
instrument cluster will flash momentarily.
Driving conditions that may activate AdvanceTracwith RSC include:
•Emergency lane-change
•Taking a turn too fast
•Quick maneuvering to avoid an accident, pedestrian or obstacle
AdvanceTracwith RSC button and icon functionality
The AdvanceTracwith RSC system automatically turns on each time the
engine is started, even if it was turned off when the engine was last shut
down. The “sliding car” icon which is located with the warning lights in the
instrument cluster will illuminate during bulb check at initial start-up and
then go off. This tells you that the system is normal and active. All
functions of the AdvanceTracwith RSC (RSC, ESC, Engine Traction
Control, and Brake Traction Control) will be activated at start up. When
the system is left active, the “sliding car” icon will flash only when any of
the components of the system are affecting the vehicle’s performance,
otherwise the light will remain off. Consequently, the “sliding car” icon will
not be illuminated during most of your normal driving.
The AdvanceTracwith RSC button,
located on the center stack of the
instrument panel, allows the driver
to control certain features of the
AdvanceTracwith RSC system
below 25 mph (40 km/h). If the
vehicle is below 25 mph (40 km/h), momentarily pressing the
AdvanceTracwith RSC button will disable RSC, ESC and Engine
Traction Control and steadily illuminate the “sliding car” icon. Pressing
and holding the AdvanceTracwith RSC button for more than five
seconds will further disable the brake portion of the Traction Control
feature and the “sliding car” icon will flash momentarily and then
illuminate steady.

CONTROL TRAC FOUR-WHEEL DRIVE (4X4) OPERATION
(IF EQUIPPED)
For important information regarding safe operation of this type
of vehicle, seePreparing to drive your vehiclein this chapter.
Do not use 4X4 mode on dry, hard surfaced roads. Doing so will produce
excessive noise, increase tire wear and may damage drive components.
4X4 mode is only intended for consistently slippery or loose surfaces.
Use of 4X4 mode on these surfaces may produce some noise (such as
occasional clunks) but will not damage drive components.
Your 4x4 features the heavy-duty Control Trac system which includes a
computer-operated transfer case. This unique system is interactive with
the road, continually monitoring and adjusting torque delivery to the
front and rear wheels to optimize vehicle control.
System indicator messages
The Control Trac system indicator messages display in the reconfigurable
telltale (RTT) location in the message center only under the following
conditions. If these messages display when driving in 4X2, contact your
authorized dealer as soon as possible. Refer toWarning lights and
chimesin theInstrument Clusterchapter.
•4X4 AUTO– displays when 4X4 AUTO is selected.
•4X4– displays when 4X4 is selected.
Positions of the Control Trac system
The Control Trac system functions
in three modes:
•4X2 (2WD)delivers power to
the rear wheels only. This is
appropriate for normal on-road
driving on dry pavement.
•4X4 AUTOprovides electronic
control four-wheel drive with power delivered to all four wheels, as
required, for increased traction. The RTT location in the message
center will display “4X4 AUTO” when this position is selected. This is
appropriate for all on-road driving conditions, such as dry road
surfaces, wet pavement, snow or gravel.

ESSENTIALS OF GOOD FUEL ECONOMY
Measuring techniques
Your best source of information about actual fuel economy is you, the
driver. You must gather information as accurately and consistently as
possible. Fuel expense, frequency of fill-ups or fuel gauge readings are
NOT accurate as a measure of fuel economy. We do not recommend
taking fuel economy measurements during the first 1,000 miles
(1,600 km) of driving (engine break-in period). You will get a more
accurate measurement after 2,000 miles-3,000 miles
(3,000 km–5,000 km).
Filling the tank
The advertised fuel capacity of the fuel tank on your vehicle is equal to
the rated refill capacity of the fuel tank as listed in theMaintenance
product specifications and capacitiessection of this chapter.
The advertised capacity is the amount of the indicated capacity and the
empty reserve combined. Indicated capacity is the difference in the
amount of fuel in a full tank and a tank when the fuel gauge indicates
empty. Empty reserve is the small amount of fuel remaining in the fuel
tank after the fuel gauge indicates empty.
The amount of usable fuel in the empty reserve varies and should
not be relied upon to increase driving range. When refueling your
vehicle after the fuel gauge indicates empty, you might not be
able to refuel the full amount of the advertised capacity of the
fuel tank due to the empty reserve still present in the tank.
For consistent results when filling the fuel tank:
•Turn the engine/ignition switch to the off position prior to refueling,
an error in the reading will result if the engine is left running.
•Use the same filling rate setting (low — medium — high) each time
the tank is filled.
•Allow no more than two automatic click-offs when filling.
•Always use fuel with the recommended octane rating.
•Use a known quality gasoline, preferably a national brand.
•Use the same side of the same pump and have the vehicle facing the
same direction each time you fill up.
