2011 JEEP LIBERTY park assist

WARNING! (Continued)
•Before using the ParkSenseRear Park Assist
System, it is strongly recommended that the ball
mount and hitch ball assembly is disconnected
from the vehicle when the vehicle is not used for
towing. Failure to do so can result in injury or
damage to vehicles or obstacles because the hitch
ball will be much closer to the obstacle than the
rear fascia when the warning display turns on the
single flashing arc and sounds the continuous
tone. Also, the sensors could detect the ball mount
and hitch ball assembly, depending on its size and
shape, giving a false indication that an obstacle is
behind the vehicle.
GARAGE DOOR OPENER — IF EQUIPPED
HomeLink replaces up to three remote controls (hand-
held transmitters) that operate devices such as garage door openers, motorized gates, lighting or home security
systems. The HomeLink
unit operates off your vehicle’s
battery.
The HomeLink buttons that are located in the headliner
or sun visor designate the three different HomeLink 
channels.

to “Tire Pressure Monitoring System” in “Starting And
Operating”.
•Check TPM System (with a single chime). Refer to
“Tire Pressure Monitoring System” in “Starting And

Oil Change Required
Your vehicle is equipped with an engine oil change
indicator system. The “Oil Change Required” message
will flash in the EVIC display for approximately 10 sec-
onds after a single chime has sounded to indicate the nextscheduled oil change interval. The engine oil change
indicator system is duty cycle based, which means the
engine oil change interval may fluctuate dependent upon
your personal driving style.
Unless reset, this message will continue to display each
time you turn the ignition switch to the ON position. To
turn off the message temporarily, press and release the
FUNCTION SELECT button. To reset the oil change
indicator system (after performing the scheduled main-
tenance), perform the following procedure:
1. Turn the ignition switch to the ON position.
Do not
start the engine.
2. Fully depress the accelerator pedal slowly three times
within 10 seconds.
3. Turn the ignition switch to the LOCK position.

310 STARTING AND OPERATING

If for some reason the power assist is interrupted, it will
still be possible to steer your vehicle. Under these condi-
tions, you will observe a substantial increase in steering
effort, especially at very low vehicle speeds and during
parking maneuvers.
NOTE:
•Increased noise levels at the end of the steering wheel
travel are considered normal and do not indicate that
there is a problem with the power steering system.
•Upon initial start-up in cold weather, the power steer-
ing pump may make noise for a short amount of time.
This is due to the cold, thick fluid in the steering
system. This noise should be considered normal, and it
does not in any way damage the steering system.
WARNING!
Continued operation with reduced power steering
assist could pose a safety risk to yourself and others.
Service should be obtained as soon as possible.
CAUTION!
Prolonged operation of the steering system at the end
of the steering wheel travel will increase the steering
fluid temperature and it should be avoided when
possible. Damage to the power steering pump may
occur.
338 STARTING AND OPERATING

•Engines may idle at higher speeds during warm-up,
which could cause rear wheels to spin and result in
loss of vehicle control. Be especially careful while
driving on slippery roads, in close-quarter maneuver-
ing, parking, or stopping.
•Do not drive too fast for road conditions, especially
when roads are wet or slushy. A wedge of water can
build up between the tire tread and the road. This
hydroplaning action can cause loss of traction, braking
ability, and control.
•After going through deep water or a car wash, brakes
may become wet, resulting in decreased performance
and unpredictable braking action. Dry the brakes by
gentle, intermittent pedal action while driving at very
slow speeds.
ELECTRONIC BRAKE CONTROL SYSTEM
Your vehicle is equipped with an advanced electronic
brake control system commonly referred to as ESC. This
system includes Anti-Lock Brake System (ABS), Traction
Control System (TCS), Brake Assist System (BAS), Hill
Start Assist (HSA), Electronic Roll Mitigation (ERM), and
Electronic Stability Control (ESC). These systems work
together to enhance both vehicle stability and control in
various driving conditions.
Two additional electronic brake control system options
are Hill Descent Control (HDC) and Trailer Sway Control
(TSC). Your vehicle may be equipped with one or both of
these options.
Anti-Lock Brake System (ABS)
This system aids the driver in maintaining vehicle control
under adverse braking conditions. The system controls
hydraulic brake pressure to prevent wheel lock-up to
344 STARTING AND OPERATING

time expires, the system will release brake pressure and
the vehicle will roll down the hill as normal. The system
will release brake pressure in proportion to amount of
throttle applied.
The following conditions must be met in order for HSA to
activate:
•The vehicle must be stopped.
•The vehicle must be on a 7% or greater incline.
•The gear selection must match vehicle uphill direction
(i.e., vehicle facing uphill is in forward gear; vehicle
backing uphill is in REVERSE gear).
•For vehicles equipped with an automatic transmission,
the HSA will work in REVERSE gear and all forward
gears. The system will not activate if the transmission
is in PARK.
WARNING!
There may be situations where the Hill Start Assist
(HSA) will not activate and slight rolling may occur,
such as on minor hills (i.e., less than 7%), or with a
loaded vehicle, or while pulling a trailer. HSA is not
a substitute for active driving involvement. It is
always the driver ’s responsibility to be attentive to
distance to other vehicles, people, and objects, and
most importantly brake operation to ensure safe
operation of the vehicle under all road conditions.
Your complete attention is always required while
driving to maintain safe control of your vehicle.
Failure to follow these warnings can result in a
collision or serious personal injury.
Towing With HSA
HSA will provide assistance during acceleration on an
incline while towing a trailer.
348 STARTING AND OPERATING

WARNING!
•If you use a trailer brake controller with your
trailer, the trailer brakes may be activated and
deactivated with the brake switch. If so, there may
not be enough brake pressure to hold both the
vehicle and the trailer on a hill when the brake
pedal is released. In order to avoid rolling down
an incline while resuming acceleration, manually
activate the trailer brake or apply more vehicle
brake pressure prior to releasing the brake pedal.
•HSA is not a parking brake. Always apply the
parking brake fully when leaving your vehicle.
Also, be certain to leave the transmission in PARK.
•Failure to follow these warnings can result in a
collision or serious personal injury.
Disabling And Enabling HSA
This feature can be turned on or turned off. To change the
current setting, proceed as follows:
For vehicles equipped with the Electronic Vehicle Infor-
mation Center (EVIC), refer to “Hill Start Assist,” under
Personal Settings (Customer Programmable Features),”
under “Electronic Vehicle Information Center (EVIC)” in
“Understanding Your Instrument Panel” for further in-
formation.
For vehicles not equipped with the EVIC, perform the
following steps:
NOTE:You must complete Steps 1 through 8 within
90 seconds.
1. Center the steering wheel (front wheels pointing
straight forward).
2. Shift the transmission into PARK.
