torque JEEP PATRIOT 2007 1.G Owners Manual

Traction Control System (TCS)
This system monitors the amount of wheel spin of each of
the driven wheels. If wheel spin is detected, brake
pressure is applied to the slipping wheel(s) and engine
power is reduced to provide enhanced acceleration and
stability. A feature of the TCS system functions similar to
a limited slip differential and controls the wheel spin
across a driven axle. If one wheel on a driven axle is
spinning faster than the other, the system will apply the
brake of the spinning wheel. This will allow more engine
torque to be applied to the wheel that is not spinning.
This feature remains active even if TCS and ESP are in
either the ªPartial Offº or ªESP Offº modes. Refer to
ªElectronic Stability Program (ESP)º in this Section of this
manual.
Brake Assist System (BAS)
The BAS is designed to optimize the vehicle's braking
capability during emergency braking maneuvers. The
system detects an emergency braking situation by sens-
ing the rate and amount of brake application and then
applies optimum pressure to the brakes. This can help
reduce braking distances. The BAS complements the
Anti-Lock Brake System (ABS). Applying the brakes very
quickly results in the best BAS assistance. To receive the
benefit of the system, you must apply continuous brak-
ing pressure during the stopping sequence. Do not
reduce brake pedal pressure unless braking is no longer
desired. Once the brake pedal is released, the BAS is
deactivated.

gravel conditions and more wheel spin than ESP would
normally allow is required to gain traction.
To turn ESP on again, momentarily depress the ªESP
Control Switchº. This will restore the normal ªESP Onº
mode of operation.
WARNING!
In the Partial ESP mode, the engine torque reduction
and stability features are desensitized. Therefore, the
enhanced vehicle stability offered by ESP is
unavailable.
NOTE:To improve the vehicle's traction when driving
with snow chains, or starting off in deep snow, sand or
gravel, it may be desirable to switch to the ªPartial Offº
mode by pressing the ESP switch. Once the situation
requiring ESP to be switched to the ªPartial Offº mode isovercome, turn ESP back on by momentarily depressing
the ªESP Control Switchº. This may be done while the
vehicle is in motion.
ESP 4WD Operating Modes
In addition to ESP ON and Partial ESP (described above
in ªESP 2WD Operating Modesº), all 4WD equipped
vehicles can also choose the following ESP operating
mode:
ESP OFF
This mode is intended for off-highway or off-road use
when ESP stability features could inhibit vehicle maneu-
verability due to trail conditions. This mode is entered by
depressing and holding the ªESP Control Switchº for 5
seconds when the vehicle is stopped and the engine is
running. After 5 seconds, the ªESP/TCS Indicator Lightº
will illuminate and the ªESP Offº message will appear in
the odometer. Press and release the trip odometer button
located on the instrument cluster to clear this message.

traction surfaces, activate the 4WD Lock switch by pull-
ing up once and releasing. This locks the center coupling
allowing more torque to be sent to the rear wheels. The
amber94WD9light will come on in the cluster. This can be
done on the fly, at any vehicle speed. To deactivate,
simply pull on the switch one more time. The cluster light
will then go out.

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

WARNING!
Never use tow straps with end hooks or link two
straps with a clevis pin. These heavy metal objects
could become projectiles if a strap breaks, which
could cause severe injury. Never leave more than 2 to
3 ft. (61 to 91 cm) of slack in the strap. More slack
than this greatly increases the risk of injury and
vehicle damage. Always keep everyone at least 30 ft.
(9 m) away from a strapping or winching situation.
After Driving Off-Road
Off-road operation puts more stress on your vehicle than
does most on-road driving. After driving off-road, it is
always a good idea to check for damage.
²Completely inspect the underbody of your vehicle.
Check tires, body structure, steering, suspension, and
exhaust system for damage.
²Check threaded fasteners for looseness, particularly on
the chassis, drivetrain components, steering, and sus-
pension. Retighten them, if required, and torque to the
values specified in the Service Manual.
²Check for accumulations of plants or brush. These
things could be a fire hazard, or they might hide
damage to fuel lines, brake hoses, axle pinion seals,
and propeller shafts.
²After extended operation in mud, sand, water, or
similar dirty conditions, have brake drums and rotors,
brake linings, and axle yokes inspected and cleaned as
soon as possible.
²If you experience unusual vibration after driving in
mud, slush or similar conditions, check the wheels for
packed material. Packed foreign material can cause a
wheel imbalance and cleaning the wheels will correct
the situation.
