2017 JEEP CHEROKEE brake light

The park brake switch is located in the center console.
To apply the park brake manually, pull up on the switch
momentarily. You may hear a slight whirring sound from
the back of the vehicle while the park brake engages. Once
the park brake is fully engaged, the BRAKE telltale light in
the instrument cluster and an indicator on the switch will
illuminate. If your foot is on the brake pedal while you
apply the park brake, you may notice a small amount of
brake pedal movement. The park brake can be applied
even when the ignition switch is OFF but the BRAKE
telltale light will not illuminate, however, it can only be
released when the ignition is in the ON/RUN mode.NOTE:
The EPB fault light will illuminate if the EPB switch
is held for longer than 20 seconds in either the released or
applied position. The light will extinguish upon releasing
the switch.
If the Auto Park Brake feature is enabled, the parking brake
will automatically engage whenever the transmission is
placed into PARK, when the ignition is turned OFF. If your
foot is on the brake pedal, you may notice a small amount
of brake pedal movement while the park brake is engaging.
The park brake will release automatically when the igni-
tion is ON, the transmission is in DRIVE or REVERSE, the
driver seat belt is buckled, and an attempt is made to drive
away.
To release the park brake manually, the ignition switch
must be in the ON/RUN mode. Put your foot on the brake
pedal, then push the park brake switch down momentarily.
You may hear a slight whirring sound from the back of the
vehicle while the parking brake disengages. You may also
notice a small amount of movement in the brake pedal.
Once the park brake is fully disengaged, The BRAKE
telltale light in the instrument cluster and the LED indica-
tor on the switch will extinguish.

NOTE:When parking on a hill, it is important to turn the
front wheels toward the curb on a downhill grade and
away from the curb on an uphill grade. Apply the park
brake before placing the gear selector in PARK, otherwise
the load on the transmission locking mechanism may make
it difficult to move the gear selector out of PARK. The
parking brake should always be applied whenever the
driver is not in the vehicle.
WARNING!
• Never use the PARK position as a substitute for the
parking brake. Always apply the parking brake fully
when parked to guard against vehicle movement and
possible injury or damage.
• When leaving the vehicle, always remove the key fob
from the ignition and lock your vehicle.
• Never leave children alone in a vehicle, or with
access to an unlocked vehicle. Allowing children to
be in a vehicle unattended is dangerous for a number
of reasons. A child or others could be seriously or
fatally injured. Children should be warned not to
touch the parking brake, brake pedal or the gear
selector.
(Continued)
WARNING! (Continued)
•Do not leave the key fob in or near the vehicle, or in
a location accessible to children, and do not leave a
vehicle equipped with Keyless Enter-N-Go in the
ACC or ON/RUN mode. A child could operate power
windows, other controls, or move the vehicle.
• Be sure the parking brake is fully disengaged before
driving; failure to do so can lead to brake failure and
a collision.
• Always fully apply the parking brake when leaving
your vehicle, or it may roll and cause damage or
injury. Also be certain to leave the transmission in
PARK. Failure to do so may allow the vehicle to roll
and cause damage or injury.
CAUTION!
If the Brake System Warning Light remains on with the
parking brake released, a brake system malfunction is
indicated. Have the brake system serviced by an au-
thorized dealer immediately.
266 STARTING AND OPERATING

If exceptional circumstances should make it necessary to
engage the park brake while the vehicle is in motion,
maintain upward pressure on the electric park brake
switch for as long as engagement is desired. The BRAKE
telltale light will illuminate, and a continuous chime will
sound. The rear stop lamps will also be illuminated auto-
matically while the vehicle remains in motion.
To disengage the park brake while the vehicle is in motion,
release the switch. If the vehicle is brought to a complete
stop using the parking brake, when the vehicle reaches
approximately 3 mph, (5 km/h) the parking brake will
remain engaged.
WARNING!
Driving the vehicle with the parking brake engaged, or
repeated use of the parking brake to slow the vehicle
may cause serious damage to the brake system. Be sure
the parking brake is fully disengaged before driving;
failure to do so can lead to brake failure and a collision.
In the unlikely event of a malfunction of the Electric Park
Brake system, a yellow EPB fault light will illuminate. This
may be accompanied by the BRAKE telltale light flashing. In this event, urgent service of the electric park brake
system is required. Do not rely on the parking brake to
hold the vehicle stationary.
Auto Park Brake
The electric park brake can be programmed to be applied
automatically whenever the vehicle is at a standstill and
the automatic transmission is placed in PARK, whenever
the ignition is turned “OFF”. Auto Park Brake is enabled
and disabled by customer selection through the customer
programmable features section of the Uconnect Settings.
Any single auto park brake application can be bypassed by
pushing the EPB switch to the release position while the
transmission is placed in PARK.
SafeHold
SafeHold is a safety feature of the Electric Park Brake
System that will engage the park brake automatically if the
vehicle is left unsecured while the ignition is in RUN.
For automatic transmissions, the park brake will automati-
cally engage if all of the following conditions are met:
•
The vehicle is at a standstill.
• There is no attempt to depress the brake pedal or
accelerator pedal.

Shift Positions
For additional information on the appropriate use of each
4WD system mode position, see the information below:
NEUTRAL
This range disengages the driveline from the powertrain. It
is to be used for flat towing behind another vehicle. Refer
to “Recreational Towing” in “Starting And Operating” for
further information.
WARNING!
You or others could be injured or killed if you leave the
vehicle unattended with the power transfer unit in the
NEUTRAL (N) position without first fully engaging
the parking brake. The NEUTRAL (N) position disen-
gages both the front and rear driveshafts from the
powertrain and will allow the vehicle to roll, even if
the transmission is in PARK. The parking brake
should always be applied when the driver is not in the
vehicle.
4WD LOW
This range is for low speed four-wheel drive. It provides an
additional gear reduction which allows for increased
torque to be delivered to both the front and rear wheels
while providing maximum pulling power for loose, slip-
pery road surfaces only. Do not exceed 25 mph (40 km/h).
NOTE:Refer to “Selec-Terrain – If Equipped” for further
information on the various positions and their intended
usages.

Metric Speed (km/h)
•Pushing the SET -button once will result in a 1 km/h
decrease in set speed. Each subsequent tap of the button
results in a decrease of 1 km/h.
• If the button is continually pushed, the set speed will
continue to decrease until the button is released, then the
new set speed will be established.
To Accelerate For Passing
Press the accelerator as you would normally. When the
pedal is released, the vehicle will return to the set speed.
To Resume Speed
To resume a previously set speed, push the RES button and
release. Resume can be used at any speed above 20 mph
(32 km/h).
To Deactivate
A soft tap on the brake pedal, pushing the CANC/Cancel
button, or normal brake pressure while slowing the vehicle
will deactivate the speed control without erasing the set
speed from memory.
Pushing the on/off button or turning the ignition switch
off erases the set speed from memory.
ADAPTIVE CRUISE CONTROL (ACC) —
IF EQUIPPED
Adaptive Cruise Control (ACC) increases the driving con-
venience provided by cruise control while traveling on
highways and major roadways. However, it is not a safety
system and not designed to prevent collisions. Electronic
Speed Control function performs differently. Please refer
to the proper section within this chapter.
ACC will allow you to keep cruise control engaged in light
to moderate traffic conditions without the constant need to
reset your cruise control. ACC utilizes a radar sensor and a
forward facing camera designed to detect a vehicle directly
ahead of you.
NOTE:
• If the sensor does not detect a vehicle ahead of you, ACC
will maintain a fixed set speed.
• If the ACC sensor detects a vehicle ahead, ACC will
apply limited braking or acceleration (not to exceed the
original set speed) automatically to maintain a preset
following distance, while matching the speed of the
vehicle ahead.
