2012 JEEP GRAND CHEROKEE brakes

NOTE:
Any chassis/suspension modifications to
the vehicle will effect the performance of the
Adaptive Cruise Control.
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 Information
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
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

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 con-
tinues 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.
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 speed-
ometer and the tachometer. The information it
displays depends on ACC system status.Menu Button
Press the MENU button (located
on the steering wheel) repeatedly
until one of the following displays
in the EVIC:
Adaptive Cruise Control Off When ACC is deactivated, the display willread “Adaptive Cruise Control Off.”
Adaptive Cruise Control Ready When ACC is activated but the vehiclespeed setting has not been selected, the
display will read “Adaptive Cruise Control
Ready.”
ACC SET When ACC is set, the set speed willdisplay.
Brake Alert

ACC Unavailable Warning
If the system turns off, and the EVIC displays
“ACC/FCW Unavailable, Vehicle System Error”,
there may be a temporary malfunction that
limits ACC functionality. Although the vehicle is
still drivable under normal conditions, ACC will
be temporarily unavailable. If this occurs, try
activating ACC again later, following a key
cycle. If the problem persists, see your autho-
rized dealer.
Service ACC Warning
If the system turns off, and the EVIC displays
“ACC/FCW Unavailable Service Radar Sen-
sor”, it indicates there is an internal system
fault. Although the vehicle is still drivable under
normal conditions, have the system checked
by an authorized dealer.
Precautions While Driving With ACCIn certain driving situations, ACC may have
detection issues. In these cases, ACC may
brake late or unexpectedly. The driver needs to
stay alert and may need to intervene.
Adding A Trailer Hitch
The weight of a trailer/hitch may affect the
performance of ACC. If there is a noticeable
change in performance following the installa-
tion of a trailer/hitch, or if the ACC performance
does not return to normal after removing the
trailer/hitch see your authorized dealer.Offset Driving
ACC may not detect a vehicle in the same lane
that is offset from your direct line of travel. There
will not be sufficient distance to the vehicle
ahead. The offset vehicle may move in and out
of the line of travel, which can cause your
vehicle to brake or accelerate unexpectedly.
Turns And Bends
In turns or bends, ACC may detect a vehicle
ahead too late or too early. This may cause your
vehicle to brake late or unexpectedly. Give
extra attention in curves and be ready to apply
the brakes if necessary. Be sure to select an
appropriate speed while driving in curves.
ACC/FCW Unavailable Warning
126

ACC may occasionally provide braking and/or
a driver alert that you consider unnecessary.
This may be the systems response to signs,
guardrails, and other stationary objects in a
curve. This may also occur at the base of steep
hills. This is normal operation and your vehicle
does not require service.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 will 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 de-
tected the vehicle changing lanes and it may
not detect the vehicle until it’s too late for the
ACC system to take action. ACC will not detect
a vehicle until it is completely in the lane. There
will not be sufficient distance to the lane-
changing vehicle. Always be attentive and
ready to apply the brakes if necessary.
127

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 will not be sufficient distance to the
vehicle ahead.
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.
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
normal Cruise Control mode is designed to
maintain a set cruising speed without requiring
the driver to operate the accelerator. Cruise
Control can only be operated if the vehicle
speed is above 18 mph (30 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 addi-
tion, the proximity warning does not activate
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.
128

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) LightThis 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
seconds.
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
driveshafts are mechanically
locked together 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 — If Equipped” 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. 19. Fuel Gauge
The pointer shows the level of fuel in the fuel
tank when the ignition switch is in the ON/RUN
position.

STARTING PROCEDURESBefore starting your vehicle, adjust your seat,
adjust the inside and outside mirrors, fasten
your seat belt, and if present, instruct all other
occupants to buckle their seat belts.
WARNING!
•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 in-
jured. 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, and do not leave a vehicle
equipped with Keyless Enter-N-Go in the
ACC or ON/RUN mode. A child could op-
erate 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 driv-
ing gear.
CAUTION!
Damage to the transmission may occur if the
following precautions are not observed:
•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.
• Do not shift from REVERSE, PARK, or
NEUTRAL into any forward gear when the
engine is above 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
pressing 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 con-
tinue 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 seconds. If this occurs, turn the ignition
switch to the LOCK position, wait 10 to 15 sec-
onds, then repeat the “Normal Starting” proce-
dure.
Keyless Enter-N-Go
This feature allows the
driver to operate the ig-
nition switch with the
push of a button, as
long as the ENGINE
START/STOP button is
installed and the Re-
mote Keyless Entry
(RKE) transmitter is in
the passenger com-
partment.
