FREEDOM DRIVE II – SAFE OFF-ROAD DRIVING
Off-Road Driving Tips and Vehicle Characteristics
The Freedom Drive II Off-Road Package has excellent on
and off-road capabilities. These off-road capabilities will
allow you to explore those wilderness trails where few
travel, providing a source of exciting and satisfying
recreation. Before you venture out you should contact
your local governmental agency to determine what are
the designated off-road vehicle (ORV) trails or recreation
areas. You should always tread lightly and only use
established roads, trails or ORV recreational areas. The
National Forest Service, Bureau of Land Management or
local Department of Natural Resources are a wealth of
information and usually have maps with marked trails.
NOTE: For optimum off-road performance, premium
fuel is recommended. However, your vehicle isequipped with an active spark knock system and can
adjust the engine calibration for a varying range of fuel
octane levels.The Freedom Drive II Off-Road Package
The Freedom Drive II Off-Road Package provides excel-
lent capability on and off-road.
The package includes:
•2.4L DOHC 16-Valve I4 (172 bhp @ 6000 RPM, 165 lb-ft
@ 4400 RPM)
•Second generation continuously variable transaxle
(CVT2L) with 19:1 crawl ratio
•Tow Hooks: two front and one rear
•Front engine and transaxle skid plate
•Fuel tank skid plate
•Air filtration system
252 STARTING AND OPERATING

•Unique Engine Calibration– When the system has
the 4WD lock lever engaged and is in the Low
Off-Road mode or reverse, the engine calibration
changes to run higher spark advance with premium
fuel for optimum off-road performance. Your vehicle is
equipped with an active spark knock system and can
adjust the engine calibration for a varying range of fuel
octane levels.High Mobility Characteristics
The Freedom Drive II Off-Road package has high off-
road mobility characteristics with an approach angle A=
29 degrees, a break-over angle B= 23 degrees, a running
ground clearance C= 9 in (23 cm), a departure angle D=
33 degrees, and a turning circle of 35.6 ft (11 m).

FUEL REQUIREMENTS
GASOLINE ENGINES
Your vehicle is designed to meet all emis-
sion regulations and provide excellent fuel
economy when using high-quality regular
unleaded gasoline with an octane rating of
87. The use of premium gasoline is not
recommended. The use of premium gaso-
line will provide no benefit over high-quality regular
gasolines and, in some circumstances may result in
poorer performance.
Light spark knock at low engine speeds is not harmful to
your engine. However, continued heavy spark knock at
high speeds can cause damage and immediate service is
required.
Poor quality gasoline can cause problems such as hard
starting, stalling and hesitations. If you experience thesesymptoms, try another brand of gasoline (with the ap-
propriate octane rating for your engine) before consider-
ing service for the vehicle.
Reformulated Gasoline
Many areas of the country require the use of cleaner
burning gasoline referred to as “reformulated gasoline”.
“Reformulated gasolines” contain oxygenates and are
specifically blended to reduce vehicle emissions and
improve air quality.
The manufacturer supports the use of “reformulated
gasolines”. Properly blended “reformulated gasolines”
will provide excellent performance and durability of
engine and fuel system components.

Gasoline/Oxygenate Blends
Some fuel suppliers blend unleaded gasoline with oxy-
genates such as 10% ethanol, MTBE, and ETBE. Oxygen-
ates are required in some areas of the country during the
winter months to reduce carbon monoxide emissions.
Fuels blended with these oxygenates may be used in
your vehicle.
CAUTION!
DO NOT use gasolines containing Methanol or E85
Ethanol. Use of these blends may result in starting
and drivability problems and may damage critical
fuel system components.
Problems that result from using methanol/gasoline
blends are not the responsibility of the manufacturer.
While MTBE is an oxygenate made from Methanol, it
does not have the negative effects of Methanol.
MMT In Gasoline
MMT is a manganese containing metallic additive that is
blended into some gasoline to increase the octane num-
ber. Gasolines blended with MMT offer no performance
advantage beyond gasolines of the same octane number
without MMT. Gasolines blended with MMT have been
shown to reduce spark plug life and reduce emission
system performance in some vehicles. The manufacturer
recommends using gasolines without MMT. Since the
MMT content of gasoline may not be indicated on the
pump, you should ask your gasoline retailer whether or
not their gasoline contains MMT.
It is even more important to look for gasolines without
MMT in Canada, because MMT can be used at levels
higher than those allowed in the United States.
MMT is prohibited in Federal and California reformu-
lated gasolines.
312 STARTING AND OPERATING

Materials Added To Fuel
All gasoline sold in the United States is required to
contain effective detergent additives. Use of additional
detergents or other additives is not needed under normal
conditions and would result in additional cost. Therefore
you should not have to add anything to the fuel.
Fuel System Cautions
CAUTION!
Follow these guidelines to maintain your vehicle’s
performance:
•The use of leaded gas is prohibited by Federal law.
Using leaded gasoline can impair engine performance
and damage the emission control system.
•An out-of-tune engine, or certain fuel or ignition
malfunctions, can cause the catalytic converter tooverheat. If you notice a pungent burning odor or
some light smoke, your engine may be out of tune or
malfunctioning and may require immediate service.
Contact your authorized dealer for service assistance.
•The use of fuel additives, which are now being sold as
octane enhancers, is not recommended. Most of these
products contain high concentrations of Methanol.
Fuel system damage or vehicle performance problems
resulting from the use of such fuels or additives is not
the responsibility of the manufacturer.
NOTE:Intentional tampering with emissions control
systems can result in civil penalties being assessed
against you.
