2013 JEEP GRAND CHEROKEE brakes

Activating Adaptive Cruise
Control (ACC)
You can only activate ACC if the vehicle speed
is above 18 mph (30 km/h).
When the system is turned on and in the
READY state, the Electronic Vehicle Informa-
tion Center (EVIC) displays “Adaptive Cruise
Ready.”
When the system is OFF, the EVIC displays
“Adaptive Cruise Control Off.”
NOTE:
You cannot enable ACC under the following
conditions:
•When in Four-Wheel Drive Low.
• When you apply the brakes.
• When the parking brake is set.
• When the automatic transmission is in
PARK, REVERSE or NEUTRAL.
• When pushing the RES + button without a
previously set speed in memory.
To ActivatePush and release the ON/OFF button. The ACC
menu in the EVIC displays “Adaptive Cruise
Control Ready.”
To turn the system OFF, push and release the
ON/OFF button again. At this time, the system
will turn off and the EVIC will display “Adaptive
Cruise Control Off.”WARNING!
Leaving the Adaptive Cruise Control (ACC)
system 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 a collision. Always leave
the system off when you are not using it.
To Set A Desired ACC SpeedWhen the vehicle reaches the speed desired,
push the SET -button and release. The EVIC
will display the set speed.

The maximum braking applied by ACC is lim-
ited; however, the driver can always apply the
brakes manually, if necessary.
NOTE:
The brake lights will illuminate whenever the
ACC system applies the brakes.
A Proximity Warning will alert the driver if ACC
predicts that its maximum braking level is not
sufficient to maintain the set distance. If this
occurs, a visual alert “BRAKE” will flash in the
EVIC and a chime will sound while ACC contin-
ues to apply its maximum braking capacity.
When this occurs, you should immediately ap-
ply the brakes as needed to maintain a safe
distance from the vehicle ahead.
The ACC Systems provides Overtake Aid when
passing on the left hand side only. When driving
with ACC engaged and following a Target ve-
hicle, the system will provide an additional
acceleration based on your current speed. The
acceleration is triggered by indicating a left turn
signal.
Adaptive Cruise Control (ACC) MenuThe EVIC displays the current ACC system
settings. The EVIC is located in the upper part
of the instrument cluster between the speedom-
eter and the tachometer. The information it
displays depends on ACC system status.
Adaptive Cruise Control Off
•When ACC is deactivated, the display will
read “Adaptive Cruise Control Off.” Adaptive Cruise Control Ready
•
When ACC is activated but the vehicle speed
setting has not been selected, the display will
read “Adaptive Cruise Control Ready.”
ACC SET
• When ACC is set, the set speed will display.
• The set speed will continue to display in
place of the odometer reading when chang-
ing the EVIC display while ACC is set.

Using ACC On Hills
When driving on hills, ACC may not detect a
vehicle in your lane. Depending on the speed,
vehicle load, traffic conditions, and the steep-
ness of the hills, ACC performance may be
limited.Lane Changing
ACC may not detect a vehicle until it is com-
pletely in the lane in which you are traveling. In
the illustration shown, ACC has not yet detected
the vehicle changing lanes and it may not detect
the vehicle until it’s too late for the ACC system
to take action. ACC may not detect a vehicle
until it is completely in the lane. There may not
be sufficient distance to the lane-changing ve-
hicle. Always be attentive and ready to apply the
brakes if necessary.Narrow Vehicles
Some narrow vehicles traveling near the outer
edges of the lane or edging into the lane are not
detected until they have moved fully into the
lane. There may not be sufficient distance to the
vehicle ahead.
129

Stationary Objects And Vehicles
ACC does not react to stationary objects and
stationary vehicles. For example, ACC will not
react in situations where the vehicle you are
following exits your lane and the vehicle ahead
is stopped in your lane. Always be attentive and
ready to apply the brakes if necessary.General Information

Normal (Fixed Speed) Cruise
Control Mode
In addition to Adaptive Cruise Control mode, a
normal (fixed speed) Cruise Control mode is
available for cruising at fixed speeds. The nor-
mal Cruise Control mode is designed to main-
tain a set cruising speed without requiring the
driver to operate the accelerator. Cruise Control
can only be operated if the vehicle speed is
above 20 mph (32 km/h).
To change between the different cruise modes,
press the MODE button when the system is in
either the OFF, READY or SET state. Pressing
of the MODE button in any state will result in
changing to the new Mode in the OFF state.
WARNING!
In the normal Cruise Control mode, the sys-
tem will not react to vehicles ahead. In
addition, the proximity warning does not ac-
tivate and no alarm will sound even if you are
too close to the vehicle ahead since neither
the presence of the vehicle ahead nor the
vehicle-to-vehicle distance is detected. Be
sure to maintain a safe distance between
your vehicle and the vehicle ahead. Always
be aware which mode is selected.
To Set A Desired Speed
When the vehicle reaches the speed desired,
press the SET -button and release. The EVIC
will display the set speed.
NOTE:
You must observe the display when setting
or changing speed, not the speedometer.

Vehicles equipped with the Anti-Lock Brake
System (ABS), are also equipped with Elec-
tronic Brake Force Distribution (EBD). In the
event of an EBD failure, the Brake Warning
Light will turn on along with the ABS Light.
Immediate repair to the ABS system is required.
Operation of the Brake Warning Light can be
checked by turning the ignition switch from the
OFF position to the ON/RUN position. The light
should illuminate for approximately two sec-
onds. The light should then turn off unless the
parking brake is applied or a brake fault is
detected. If the light does not illuminate, have
the light inspected by an authorized dealer.
The light also will turn on when the parking
brake is applied with the ignition switch in the
ON/RUN position.
NOTE:
This light shows only that the parking brake
is applied. It does not show the degree of
brake application.15. Anti-Lock Brake (ABS) Light
This light monitors the Anti-Lock
Brake System (ABS). The light will
turn on when the ignition switch is
turned to the ON/RUN position and
may stay on for as long as four sec-
onds.
If the ABS light remains on or turns on while
driving, it indicates that the Anti-Lock portion of
the brake system is not functioning and that
service is required. However, the conventional
brake system will continue to operate normally if
the BRAKE warning light is not on.
If the ABS light is on, the brake system should
be serviced as soon as possible to restore the
benefits of Anti-Lock brakes. If the ABS light
does not turn on when the ignition switch is
turned to the ON/RUN position, have the light
inspected by an authorized dealer. 16. 4 LOW
This light alerts the driver that the
vehicle is in the four-wheel drive
LOW mode. The front and rear drive-
shafts are mechanically locked to-
gether forcing the front and rear
wheels to rotate at the same speed. Low range
provides a greater gear reduction ratio to provide
increased torque at the wheels.
For further information on four-wheel drive op-
eration and proper use, refer to “Four-Wheel
Drive Operation” in “Starting And Operating”.
17. Speedometer
Indicates vehicle speed.
18. Fuel Door Reminder
The fuel pump symbol points to the
side of the vehicle where the fuel
door is located.

adjust the inside and outside mirrors, fasten
your seat belt, and if present, instruct all other
occupants to buckle their seat belts.
WARNING!
•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. Allow-
ing 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 shift lever.
(Continued)
WARNING!(Continued)
•Do not leave the key fob in or near the
vehicle (or in a location accessible to chil-
dren), 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.
Automatic TransmissionThe shift lever must be in the NEUTRAL or PARK
position before you can start the engine. Apply the
brakes before shifting into any driving gear.
CAUTION!
Damage to the transmission may occur if the
following precautions are not observed:
•Do not shift from REVERSE, PARK, or
NEUTRAL into any forward gear when the
engine is above idle speed.
(Continued)
CAUTION!(Continued)
•Shift into PARK only after the vehicle has
come to a complete stop.
• Shift into or out of REVERSE only after the
vehicle has come to a complete stop and
the engine is at idle speed.
• Before shifting into any gear, make sure
your foot is firmly on the brake pedal.
Using Fob With Integrated Key (Tip Start)
NOTE:
Normal starting of either a cold or a warm
engine is obtained without pumping or press-
ing the accelerator pedal.
Do not press the accelerator. Use the Fob with
Integrated Key to briefly turn the ignition switch to
the START position and release it as soon as the
starter engages. The starter motor will continue to
run, and it will disengage automatically when the
engine is running. If the engine fails to start, the
starter will disengage automatically in 10 sec-
onds. If this occurs, turn the ignition switch to the
LOCK position, wait 10 to 15 seconds, then
repeat the “Normal Starting” procedure.

WARNING!(Continued)
•When leaving the vehicle, always remove
the key fob and lock your vehicle.
• Never leave children alone in a vehicle, or
with access to an unlocked vehicle. Allow-
ing 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 shift
lever.
•
Do not leave the key fob in or near the
vehicle (or in a location accessible to chil-
dren), and do not leave Keyless Enter-N-
Go™ in the ACC or ON/RUN position.
A child could operate power windows, other
controls, or move the vehicle.
Key Ignition Park InterlockThis vehicle is equipped with a Key Ignition Park
Interlock which requires the shift lever to be in
PARK before the ignition switch can be turned
to the OFF position. The key fob can only be
removed from the ignition when the ignition is in
the OFF position, and the shift lever is locked in
PARK whenever the ignition switch is in the
OFF position.
NOTE:
If a malfunction occurs, the system will trap
the key fob in the ignition switch to warn you
that this safety feature is inoperable. The
engine can be started and stopped but the
key fob cannot be removed until you obtain
service.
Brake/Transmission Shift Interlock
System
This vehicle is equipped with a Brake Transmis-
sion Shift Interlock system (BTSI) that holds the
shift lever in PARK unless the brakes are ap-
plied. To shift the transmission out of PARK, the
ignition switch must be turned to the ON/RUN
position (engine running or not) and the brake
pedal must be pressed.
Five-Speed Automatic Transmission
(3.6L and 3.0L Diesel Engine) — If
Equipped
The shift lever position display (located in the
instrument cluster) indicates the transmission
gear range. You must press the brake pedal to
move the shift lever out of PARK (refer to
“Brake/Transmission Shift Interlock System” in
this section). To drive, move the shift lever from
PARK or NEUTRAL to the DRIVE position.
The electronically-controlled transmission pro-
vides a precise shift schedule. The transmission
electronics are self-calibrating; therefore, the
first few shifts on a new vehicle may be some-
what abrupt. This is a normal condition, and
precision shifts will develop within a few hun-
dred miles (kilometers).
Only shift from DRIVE to PARK or REVERSE
when the accelerator pedal is released and the
vehicle is stopped. Be sure to keep your foot on
the brake pedal when shifting between these
gears.
