towingin theTires, Wheels and Loadingchapter.)
Roll Stability Control(RSC)
The RSC system works in conjunction with the AdvanceTrac
system 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 AdvanceTrac
with RSC include:
•Emergency lane-change
•Taking a turn too fast
•Quick maneuvering to avoid an accident, pedestrian or obstacle
AdvanceTrac
with RSC button and icon functionality
The AdvanceTrac
with 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 AdvanceTrac
with 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 AdvanceTrac
with RSC button,
located on the center stack of the
instrument panel, allows the driver
to control certain features of the
AdvanceTrac
with RSC system
below 25 mph (40 km/h). If the
vehicle is below 25 mph (40 km/h), momentarily pressing the
AdvanceTrac
with RSC button will disable RSC, ESC and Engine
Traction Control and steadily illuminate the “sliding car” icon. Pressing
and holding the AdvanceTrac
with 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.

Aggressive driving in any road conditions can cause you to lose
control of your vehicle increasing the risk of severe personal
injury or property damage. The occurrence of a AdvanceTrac
with
RSC event is an indication that at least some of the tires have
exceeded their ability to grip the road; this may lead to an increased
risk of loss of vehicle control, vehicle rollover, personal injury and
death. If you experience a severe road event, SLOW DOWN.
If a failure is detected in the AdvanceTrac
with RSC system, and the
AdvanceTrac
with RSC button has not been pushed, the warning
indicator light in the instrument cluster will stay on. If the warning
indicator light in the instrument cluster remains on while the engine is
running, have the system serviced by an authorized dealer immediately.
STEERING
To help prevent damage to the power steering system:
•Never hold the steering wheel at its furthest turning points (until it
stops) for more than a few seconds when the engine is running
•Do not operate the vehicle with a low power steering pump fluid level
(below the MIN mark on the reservoir).
•Some noise is normal during operation. If the noise is excessive, check
for low power steering pump fluid level before seeking service by your
authorized dealer.
•Heavy or uneven steering efforts may be caused by low power steering
pump fluid level. Check for low power steering pump fluid level before
seeking service by your authorized dealer.
•Do not fill the power steering pump reservoir above the MAX mark on
the reservoir, as this may result in leaks from the reservoir.
If the power steering system breaks down (or if the engine is turned
off), you can steer the vehicle manually, but it takes more effort. If the
steering wanders or pulls, check for:
•an improperly inflated tire
•uneven tire wear
•loose or worn suspension components
•loose or worn steering components
•improper steering alignment
A high crown in the road or high crosswinds may also make the steering
seem to wander/pull.

For vehicles with overflow coolant systems with a non-pressurized cap
on the coolant recovery system, add coolant to the coolant recovery
reservoir when the engine is cool. Add the proper mixture of coolant and
water to the “FULL COLD” level. For all other vehicles, which have a
coolant degas system with a pressurized cap, or if it is necessary to
remove the coolant pressure relief cap on the radiator of a vehicle with
an overflow system, follow these steps to add engine coolant.
To reduce the risk of personal injury, make sure the engine is
cool before unscrewing the coolant pressure relief cap. The
cooling system is under pressure; steam and hot liquid can come out
forcefully when the cap is loosened slightly.
1. Before you begin, turn the engine off and let it cool.
2. When the engine is cool, wrap a thick cloth around the coolant
pressure relief cap on the coolant reservoir (a translucent plastic bottle).
Slowly turn cap counterclockwise (left) until pressure begins to release.
3. Step back while the pressure releases.
4. When you are sure that all the pressure has been released, use the
cloth to turn it counterclockwise and remove the cap.
5. Fill the coolant reservoir slowly with the proper coolant mixture (see
above), to within the “COLD FILL RANGE” or the “FULL COLD” level on
the reservoir. If you removed the radiator cap in an overflow system, fill
the radiator until the coolant is visible and radiator is almost full.
6. Replace the cap. Turn until tightly installed (until “clicks” are heard).
(Cap must be tightly installed to prevent coolant loss.)
After any coolant has been added, check the coolant concentration, refer
toChecking engine coolantsection. If the concentration is not 50/50
(protection to –34° F/–36° C), drain some coolant and adjust the
concentration. It may take several drains and additions to obtain a 50/50
coolant concentration.
Whenever coolant has been added, the coolant level in the coolant
reservoir should be checked the next few times you drive the vehicle. If
necessary, add enough 50/50 concentration of engine coolant and
distilled water to bring the liquid level to the proper level.
If you have to add more than 1.0 quart (1.0 liter) of engine coolant per
month, have your authorized dealer check the engine cooling system.
Your cooling system may have a leak. Operating an engine with a low
level of coolant can result in engine overheating and possible engine
damage.

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.

•Revving the engine before turning it off may reduce fuel economy.
•Using the air conditioner or defroster may reduce fuel economy.
•You may want to turn off the speed control in hilly terrain if
unnecessary shifting between the top gears occurs. Unnecessary
shifting of this type could result in reduced fuel economy.
•Warming up a vehicle on cold mornings is not required and may
reduce fuel economy.
•Resting your foot on the brake pedal while driving may reduce fuel
economy.
•Combine errands and minimize stop-and-go driving.
Maintenance
•Keep tires properly inflated and use only recommended size.
•Operating a vehicle with the wheels out of alignment will reduce fuel
economy.
•Use recommended engine oil. Refer toMaintenance product
specifications and capacitiesin this chapter.
•Perform all regularly scheduled maintenance items. Follow the
recommended maintenance schedule and owner maintenance checks
found inscheduled maintenance information.
Conditions
•Heavily loading a vehicle or towing a trailer may reduce fuel economy
at any speed.
•Carrying unnecessary weight may reduce fuel economy (approximately
1 mpg [0.4 km/L] is lost for every 400 lb [180 kg] of weight carried).
•Adding certain accessories to your vehicle (for example bug
deflectors, rollbars/light bars, running boards, ski/luggage racks) may
reduce fuel economy.
•Fuel economy may decrease with lower temperatures during the first
8–10 miles (12–16 km) of driving.
•Driving on flat terrain offers improved fuel economy as compared to
driving on hilly terrain.
•Transmissions give their best fuel economy when operated in the top
cruise gear and with steady pressure on the gas pedal.
•Four-wheel-drive operation (if equipped) is less fuel efficient than
two-wheel-drive operation.
•Close windows for high speed driving.
