PATRIOT FREEDOM DRIVE II ± SAFE OFF-ROAD
DRIVING
Off-Road Driving Tips and Vehicle Characteristics
The Patriot with 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 andsatisfying 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 Man-
agement 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 is
equipped with an active spark knock system and can
adjust the engine calibration for varying range of fuel
octane levels.The Patriot's Freedom Drive II Off-Road Package

Freedom Drive II 4WD System Operation
Under normal driving conditions, the vehicle operates in
the active four wheel drive mode. Pulling up on the 4WD
lock lever activates the 4WD system and lights the amber
4WD cluster light. This commands a higher torque to the
rear wheels, for improved traction capability on slippery
248 STARTING AND OPERATING

roads. The active four wheel drive mode has the same
functionality with the Freedom Drive I system. Shifting
the transaxle gear select lever into Low Off-Road mode
with the 4WD lock lever active, lights the amber off-road
and 4WD cluster lights. This off-road mode gives the
combined benefits of a 19:1 crawl ratio, hill descent
braking, optimum off-road performance with premium
fuel, and off-road brake traction control for improved
traction capability off-road. In low, the transaxle (CVT2L)
initially maintains the 19:1 crawl ratio before changing
ratio. This low ratio is ideal for crawling over obstacles.
Freedom Drive II ± Off-Road Features
The following are key off-road features which are active
when the system has the 4WD lock lever engaged and is
in the Low Off-Road mode.
²Hill descent Braking± Hill descent braking uses the
vehicle braking system to provide a controlled descent
down varying grades. This feature is only active whenthe system has the 4WD lock lever engaged and is in
the Low Off-Road mode or reverse. Hill descent
braking can be turned off by turning off ESP. The hill
decent control speed varies between 4-6 mph (6 -10
km/h) forward, 3 mph (5 km/h) reverse.
²Off-Road Brake Traction Control± When conditions
warrant, the vehicle braking system transfers torque
from side to side. It does not control throttle input
unlike normal traction control which is active in
normal drive mode.
²19.1 Crawl Ratio± When the system has the 4WD lock
lever engaged and is in the Low Off-Road mode, the
CVT2L initially maintains the 19:1 crawl ratio before
changing ratio. This low ratio is ideal for crawling over
obstacles.
²4WD Lock Mode± Four wheel drive lock mode
commands a higher torque to the rear wheels, for
STARTING AND OPERATING 249

improved traction capability off-road. It also, turns on
other system features in conjunction with L Off-Road
mode.
²Unique 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 varying range of fuel
octane levels.
High Mobility Characteristics
The Patriot with the Freedom Drive II Off-Road package
has high off-road mobility characteristics with an ap-
proach angle A= 29 degrees, a break-over angle B= 23
degrees, a running ground clearance C= 9 ins. (23 cm), a
departure angle D= 33 degrees, and a turning circle of
35.6 ft. (11 m).

ADDING FUEL
Fuel Filler Cap (Gas Cap)
The gas cap is 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.
CAUTION!
Damage to the fuel system or emission control sys-
tem could result from using an improper fuel tank
filler tube cap (gas cap). A poorly fitting cap could let
impurities into the fuel system.
CAUTION!
A poorly fitting gas cap may cause the Malfunction
Indicator Light to turn on.
CAUTION!
To avoid fuel spillage and overfilling, do not ªtop
offº the fuel tank after filling.

NOTE:When the fuel nozzle ªclicksº or shuts off, the
fuel tank is full.
WARNING!
²Never have any smoking materials lit in or near
the vehicle when the gas cap is removed or the
tank filled.
²Never add fuel when the engine is running. This is
in violation of most state and federal fire regula-
tions and will cause the malfunction indicator
light to turn on.
NOTE:Tighten the gas cap about 1/4 turn until you
hear one click. This is an indication that cap is properly
tightened.If the gas cap is not tighten properly, the Malfunction
Indicator Light will come on. Be sure the gas cap is
tightened every time the vehicle is refueled.
WARNING!
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.
Loose Fuel Filler Cap Message
If the vehicle diagnostic system determines that the fuel
filler cap is loose or improperly installed, a ªGASCAPº
message will be displayed in the Odometer/Trip Odom-
eter in the instrument cluster. Refer to ªInstrument
Cluster Descriptionº in Section 4 of this manual. Tighten
the fuel filler cap properly and press the odometer/trip

Loose Fuel Filler Cap Message
After fuel is added, the vehicle diagnostic system can
determine if the fuel filler cap is possible loose or
improperly installed. A GASCAP message will be dis-
played in the instrument cluster. Tighten the gas cap until
a9clicking9sound is heard. This is an indication that the
gas cap is properly tightened. Press the trip odometer
reset button to turn off the message. If the problem
persists, the message will appear the next time the
vehicle is started. This might indicate a damaged cap. If
the problem is detected twice in a row, the system will
turn on the Malfunction Indicator Light (MIL). Resolving
the problem will turn the MIL light off.
EMISSIONS INSPECTION AND MAINTENANCE
PROGRAMS
In some localities, it may be a legal requirement to pass
an inspection of your vehicle's emissions control system.
Failure to pass could prevent vehicle registration.
For states, which have an I/M (Inspection and
Maintenance) requirement, this check verifies the
following: the MIL (Malfunction Indicator Light)
is functioning and is not on when the engine is running,
and that the OBD (On Board Diagnostic) system is ready
for testing.
Normally, the OBD system will be ready. The OBD
system maynotbe ready if your vehicle was recently
serviced, if you recently had a dead battery, or a battery
replacement. If the OBD system should be determined
not ready for the I/M test, your vehicle may fail the test.
