2007 JEEP LIBERTY brake

Automatic Transmission — If Equipped
To remove the ignition key, place the gearshift lever in P
(Park), turn the ignition key to LOCK and remove the
key.WARNING!
Leaving children in a vehicle unattended is danger-
ous for a number of reasons. A child or others could
be injured. Children should be warned not to touch
the parking brake, brake pedal, or the gear selector
lever. Do not leave the keys in the ignition. A child
could operate power windows, other controls, or
move the vehicle.
CAUTION!
An unlocked vehicle is an invitation to thieves.
Always remove the key from the ignition, and lock
all doors when leaving the vehicle unattended.

Instrument Panel and Interior Lights
When the multi-function control lever is in the parklight,
or headlight position, rotating the center portion of the
lever up and down will increase and decrease the bright-
ness (dimmer control) of the instrument panel lights. Full
daytime brightness on all electronic displays (odometer,
overhead console, radio, and climate control) is obtained
by rotating the center portion of the control to the first
detent above the dimmer range. Rotating the control to
the second detent above the dimmer range turns the
interior lights on. Rotating the control to the “Off”
(extreme bottom) position disables all the interior lights,
even when the doors and liftgate are open. While in the
“Off” position the instrument panel lighting is at the
lowest light level and may not be suitable for night
driving.
Daytime Running Lights — If Equipped
The high beam headlights come on at a low intensity
level after the engine has started. The lights remain on
until the ignition switch is turned OFF or the parking
brake is engaged. The headlight switch must be used for
normal night time driving.
Lights-On Reminder
A chime will sound if the driver’s door is left open, and
the headlights or parking lights are left on.
Fog Lights — If Equipped
The front fog light switch is located in the multi-
function control lever. To activate the fog lights,
turn on the park or low beam headlights and pull
out the end of the lever. The “Fog Light Indicator Light”
will illuminate when the fog lights are on.
NOTE:The fog lights will only operate with the park
lights or the headlights on low beam. Selecting high
beam headlights will turn off the fog lights.

To Set At A Desired Speed
When the vehicle has reached the desired speed, press
and release the SET button. Release the accelerator and
the vehicle will operate at the selected speed.
To Deactivate
A soft tap on the brake pedal, normal braking, or pressing
the CANCEL button will deactivate the Speed Control
without erasing the memory. Pressing the ON·OFF but-
ton or turning off the ignition erases the memory.
To Resume Speed
To resume a previously set speed, press and release the
RES·ACCEL button. Resume can be used at any speed
beginning at approximately 30 mph (48 km/h).
To Vary The Speed Setting
When the Speed Control is on and set, speed can be
increased by pressing and holding the RES·ACCEL but-
ton. When the button is released, a new set speed will be
established.
Tapping the RES·ACCEL button once will result in a 2
mph (3 km/h) speed increase. Each time the button is
tapped, speed increases, so tapping the button three
times will increase speed by 6 mph (9 km/h), etc.
To decrease speed while speed control is on and set, press
and hold the DECEL button. Release the button when the
desired speed is reached, and the new speed will be set.
Tapping the DECEL button once will result in a 1 mph (2
km/h) speed decrease. Each time the button is tapped,
speed decreases.

To Accelerate for Passing
Depress the accelerator as you would normally. When the
pedal is released, the vehicle will return to the set speed.
NOTE:When driving uphill, at elevations above 2,000
ft. (610 meters), or when the vehicle is heavily loaded
(especially when towing) the vehicle may slow below the
SET speed. (If the vehicle speed drops below 35 mph (56
km/h), the Speed Control will automatically disengage).
If this happens, you can push down on the accelerator
pedal to maintain the desired speed.
A full throttle (high RPM) acceleration, while the system
is engaged, will cause the system to disengage.
Vehicles may exhibit several 4-3 downshifts under the
above conditions. To reduce the frequency of the down-
shifts and to improve vehicle performance, it is advisable
to lock out overdrive. Press the O/D OFF button on the
right side of the shift lever.WARNING!
Leaving the Speed Control on when not in use is
dangerous. You could accidentally set the system or
cause it to go faster than you want. You could lose
control and have an accident. Always turn the system
off when you are not using it.
ELECTRONIC BRAKE CONTROL SYSTEM
Your vehicle is equipped with an advanced electronic
brake control system that includes ABS (Anti-Lock Brake
System), TCS (Traction Control System), BAS (Brake
Assist System), ERM (Electronic Roll Mitigation) and ESP
(Electronic Stability Program). All five systems work
together to enhance vehicle stability and control in vari-
ous driving conditions are commonly referred to as ESP.

ABS (Anti-Lock Brake System)
This system aids the driver in maintaining vehicle control
under adverse braking conditions. The system controls
hydraulic brake pressure to prevent wheel lock-up and
help avoid skidding on slippery surfaces during braking.
Refer to “Anti-Lock Brake System” in Section 5 of this
manual for more information about ABS.
WARNING!
ABS (Anti-Lock Brake System) cannot prevent the
natural laws of physics from acting on the vehicle,
nor can it increase the traction afforded by prevail-
ing road conditions. ABS cannot prevent accidents,
including those resulting from excessive speed in
turns, driving on very slippery surfaces, or hydro-
planing. Only a safe, attentive, and skillful driver
can prevent accidents. The capabilities of an ABS-
equipped vehicle must never be exploited in a reck-
less or dangerous manner which could jeopardize
the user’s safety or the safety of others.
126 UNDERSTANDING THE FEATURES OF YOUR VEHICLE

TCS (Traction Control System)
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 the
“Partial Off” mode. Refer to “ESP (Electronic Stability
Program)” in this section.
BAS (Brake Assist System)
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.

WARNING!
BAS (Brake Assist System) cannot prevent the natu-
ral laws of physics from acting on the vehicle, nor
can it increase the traction afforded by prevailing
road conditions. BAS cannot prevent accidents, in-
cluding those resulting from excessive speed in
turns, driving on very slippery surfaces, or hydro-
planing. Only a safe, attentive, and skillful driver
can prevent accidents. The capabilities of a BAS-
equipped vehicle must never be exploited in a reck-
less or dangerous manner which could jeopardize
the user’s safety or the safety of others.
ERM (Electronic Roll Mitigation)
This system anticipates the potential for wheel lift by
monitoring the driver ’s steering wheel input and the
speed of the vehicle. When ERM determines that the rate
of change of the steering wheel angle and vehicles speed
are sufficient to potentially cause wheel lift, it applies the
appropriate brake and may reduce engine power to
lessen the chance that wheel lift will occur. ERM will only
intervene during very severe or evasive driving maneu-
vers. ERM can only reduce the chance of wheel lift
occurring during severe or evasive driving maneuvers. It
can not prevent wheel lift due to other factors such as
road conditions, leaving the roadway or striking objects
or other vehicles.
