2013 JEEP GRAND CHEROKEE warning

Power Steering Fluid CheckChecking the power steering fluid level at a
defined service interval is not required. The fluid
should only be checked if a leak is suspected,
abnormal noises are apparent, and/or the sys-
tem is not functioning as anticipated. Coordi-
nate inspection efforts through an authorized
dealer.
CAUTION!
Do not use chemical flushes in your power
steering system as the chemicals can dam-
age your power steering components. Such
damage is not covered by the New Vehicle
Limited Warranty.
WARNING!
Fluid level should be checked on a level sur-
face and with the engine off to prevent injury
from moving parts and to ensure accurate fluid
level reading. Do not overfill. Use only manu-
facturer’s recommended power steering fluid.
If necessary, add fluid to restore to the proper
indicated level. With a clean cloth, wipe any
spilled fluid from all surfaces. Refer to “Fluids,
Lubricants, and Genuine Parts” in “Maintaining
Your Vehicle” for further information.
PARKING BRAKE
Before leaving the vehicle, make sure that the
parking brake is fully applied and place the shift
lever in the PARK position.
The foot operated parking brake is located
below the lower left corner of the instrument
panel. To apply the park brake, firmly push the
park brake pedal fully. To release the parking
brake, press the park brake pedal a second
time and let your foot up as you feel the brake
disengage.When the parking brake is applied with the
ignition switch in the ON position, the “Brake
Warning Light” in the instrument cluster will
illuminate.
NOTE:
•
When the parking brake is applied and the
transmission is placed in gear, the “Brake
Warning Light” will flash. If vehicle speed
is detected, a chime will sound to alert the
driver. Fully release the parking brake
before attempting to move the vehicle.
Parking Brake
250

•This light only shows that the parking
brake is applied. It does not show the
degree of brake application.
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 parking brake before placing
the shift lever in PARK, otherwise the load on
the transmission locking mechanism may make
it difficult to move the shift lever 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 substi-
tute for the parking brake. Always apply
the parking brake fully when parked to
guard against vehicle movement and pos-
sible injury or damage.
(Continued)
WARNING!(Continued)
•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 seri-
ously 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 the ignition of a
vehicle equipped with Keyless Enter-N-
Go™ in the ACC or ON/RUN position. A
child could operate power windows, other
controls, or move the vehicle.
• Be sure the parking brake is fully disen-
gaged before driving; failure to do so can
lead to brake failure and a collision.
(Continued)
WARNING!(Continued)
•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 Warning Light” remains on with
the parking brake released, a brake system
malfunction is indicated. Have the brake
system serviced by an authorized dealer
immediately.

ELECTRONIC BRAKE
CONTROL SYSTEM
Your vehicle is equipped with an advanced elec-
tronic brake control system that includes the
Anti-Lock Brake System (ABS), Traction Control
System (TCS), Brake Assist System (BAS), Elec-
tronic Roll Mitigation (ERM), and Electronic Sta-
bility Control (ESC). All five of these systems work
together to enhance vehicle stability and control in
various driving conditions.
Also, your vehicle is equipped with Trailer Sway
Control (TSC), Hill Start Assist (HSA), Brake
Lock Differential (BLD), Ready Alert Braking,
Rain Brake Support and, if it has four-wheel
drive with the MP 3023 two-speed transfer
case, Hill Descent Control (HDC).
Anti-Lock Brake System (ABS)This system aids the driver in maintaining ve-
hicle control under adverse braking conditions.
The system controls hydraulic brake pressure
to prevent wheel lock-up and help avoid skid-
ding on slippery surfaces during braking. Refer
to “Anti-Lock Brake System” in “Starting and
Operating” for further information.
WARNING!
The ABS cannot prevent the natural laws of
physics from acting on the vehicle, nor can it
increase the traction afforded by prevailing
road conditions. The ABS cannot prevent
collisions, including those resulting from ex-
cessive speed in turns, driving on very slip-
pery surfaces, or hydroplaning. The capabili-
ties of an ABS-equipped vehicle must never
be exploited in a reckless or dangerous
manner which could jeopardize the user’s
safety or the safety of others.
Traction Control System (TCS)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 slip-
ping wheel(s) and engine power is reduced to
provide enhanced acceleration and stability.
A feature of the TCS system, Brake Limited
Differential (BLD), functions similar to a limited-
slip differential and controls the wheel spin
across a driven axle. If one wheel on a drivenaxle is spinning faster than the other, the sys-
tem 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 ESC system is in the
“Partial Off” mode. Refer to “Electronic Stability
Control (ESC)” in this section for further infor-
mation.
Brake Assist System (BAS)The BAS is designed to optimize the vehicle’s
braking capability during emergency braking
maneuvers. The system detects an emergency
braking situation by sensing the rate and
amount of brake application and then applies
optimum pressure to the brakes. This can help
reduce braking distances. The BAS comple-
ments the anti-lock brake system (ABS). Apply-
ing the brakes very quickly results in the best
BAS assistance. To receive the benefit of the
system, you must apply
continuousbraking
pressure during the stopping sequence (do not
“pump” the brakes). Do not reduce brake pedal
pressure unless braking is no longer desired.
Once the brake pedal is released, the BAS is
deactivated.
252

WARNING!
•The BAS cannot prevent the natural laws
of physics from acting on the vehicle, nor
can it increase the traction afforded by
prevailing road conditions.
• The BAS cannot prevent collisions, includ-
ing those resulting from excessive speed
in turns, driving on very slippery surfaces,
or hydroplaning.
•
The capabilities of a BAS-equipped vehicle
must never be exploited in a reckless or
dangerous manner which could jeopardize
the user’s safety or the safety of others.
Electronic Roll Mitigation (ERM)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 steer-
ing wheel angle and vehicle’s speed are suffi-
cient to potentially cause wheel lift, it then
applies the appropriate brake and may also 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 ma-
neuvers. It cannot prevent wheel lift due to other
factors, such as road conditions, leaving the
roadway, or striking objects or other vehicles.
WARNING!
Many factors, such as vehicle loading, road
conditions, and driving conditions, influence
the chance that wheel lift or rollover may
occur. ERM cannot prevent all wheel lift or
rollovers, especially those that involve leav-
ing the roadway or striking objects or other
vehicles. The capabilities of an ERM-
equipped vehicle must never be exploited in
a reckless or dangerous manner, which
could jeopardize the user’s safety or the
safety of others.
Electronic Stability Control (ESC)This system enhances directional control and
stability of the vehicle under various driving
conditions. ESC corrects for oversteering or
understeering of the vehicle by applying the
brake of the appropriate wheel to assist in
counteracting the oversteer or understeer con-
dition. Engine power may also be reduced to
help the vehicle maintain the desired path.
ESC uses sensors in the vehicle to determine
the vehicle path intended by the driver and
compares it to the actual path of the vehicle.
When the actual path does not match the
intended path, ESC applies the brake of the
appropriate wheel to assist in counteracting the
oversteer or understeer condition.
•
Oversteer - when the vehicle is turning more
than appropriate for the steering wheel posi-
tion.
• Understeer - when the vehicle is turning less
than appropriate for the steering wheel posi-
tion.
253

The “ESC Activation/Malfunction Indicator Light”
located in the instrument cluster will start to flash
as soon as the tires lose traction and the ESC
system becomes active. The “ESC Activation/
Malfunction Indicator Light” also flashes when the
TCS is active. If the “ESC Activation/Malfunction
Indicator Light” begins to flash during accelera-
tion, ease up on the accelerator and apply as little
throttle as possible. Be sure to adapt your speed
and driving to the prevailing road conditions.
WARNING!
The Electronic Stability Control (ESC) can-
not prevent the natural laws of physics from
acting on the vehicle, nor can it increase the
traction afforded by prevailing road condi-
tions. ESC cannot prevent collisions, includ-
ing those resulting from excessive speed in
turns, driving on very slippery surfaces, or
hydroplaning. ESC also cannot prevent col-
lisions resulting from loss of vehicle control
due to inappropriate driver input for the con-
ditions. Only a safe, attentive, and skillful
(Continued)
WARNING!(Continued)
driver can prevent collisions. The capabilities
of an ESC equipped vehicle must never be
exploited in a reckless or dangerous manner
which could jeopardize the user’s safety or
the safety of others.
The ESC system has two available operating
modes in 4WD HIGH range and two-wheel
drive vehicles, and one operating mode in 4WD
LOW range.
High Range (Four-Wheel Drive Models)
On
This is the normal operating mode for ESC in
4WD HIGH range. Whenever the vehicle is
started or the transfer case (if equipped) is
shifted from 4WD LOW range or NEUTRAL
back to 4WD HIGH range, the ESC system will
be in this “On” mode. This mode should be used
for most driving situations. ESC should only be
turned to “Partial Off” mode for specific reasons
as noted below. Partial Off
This mode is entered by momentarily pressing
the “ESC OFF” switch. When in “Partial Off”
mode, the TCS portion of ESC, except for the
BLD feature described in the TCS section, has
been disabled and the “ESC Off Indicator Light”
will be illuminated. All other stability features of
ESC function normally. This mode is intended to
be used if the vehicle is in deep snow, sand, or
gravel conditions and more wheel spin than
ESC would normally allow is required to gain
traction. To turn ESC on again, momentarily
press the “ESC OFF” switch. This will restore
the normal “ESC On” mode of operation.
When in “Partial Off” mode, the TCS functional-
ity of ESC, (except for the limited slip feature
described in the TCS section), has been dis-
abled and the “ESC Off Indicator Light” will be
illuminated. All other stability features of ESC
function normally. When in “Partial Off” mode,
the engine power reduction feature of TCS is
disabled, and the enhanced vehicle stability
offered by the ESC system is reduced.
254

NOTE:
To improve the vehicle’s traction when driv-
ing with snow chains, or starting off in deep
snow, sand, or gravel, it may be desirable to
switch to the “Partial Off” mode by pressing
the “ESC OFF” switch. Once the situation
requiring ESC to be switched to the “Partial
Off” mode is overcome, turn ESC back on by
momentarily pressing the “ESC OFF”
switch. This may be done while the vehicle
is in motion.
WARNING!
•When in "Partial Off" mode, the TCS func-
tionality of ESC, (except for the limited slip
feature described in the TCS section), has
been disabled and the "ESC Off Indicator
Light" will be illuminated. When in "Partial
Off" mode, the engine power reduction
feature of TCS is disabled, and the en-
hanced vehicle stability offered by the ESC
system is reduced.
• Trailer Sway control (TSC) is disabled
when the ESC system is in the "Partial Off"
mode.
4WD Low Range
Partial Off
This is the normal operating mode for ESC in
4WD LOW range. Whenever the vehicle is
started in 4WD LOW range, or the transfer case
(if equipped) is shifted from 4WD HIGH range or
NEUTRAL to 4WD LOW range, the ESC sys-
tem will be in the “Partial Off” mode.Trailer Sway Control (TSC)TSC uses sensors in the vehicle to recognize
an excessively swaying trailer and will take the
appropriate actions to attempt to stop the sway.
The system may reduce engine power and
apply the brake of the appropriate wheel(s) to
counteract the sway of the trailer. TSC will
become active automatically once an exces-
sively swaying trailer is recognized. No driver
action is required. Note that TSC cannot stop all
trailers from swaying. Always use caution when
towing a trailer and follow the trailer tongue
weight recommendations. Refer to “Trailer Tow-
ing” in “Starting and Operating” for further infor-
mation. When TSC is functioning, the “ESC
Activation/Malfunction Indicator Light” will flash,
the engine power may be reduced and you may
feel the brakes being applied to individual
wheels to attempt to stop the trailer from sway-
ing. TSC is disabled when the ESC system is in
the “Partial Off” mode.
ESC OFF Switch
255

WARNING!
If TSC activates while driving, slow the vehicle
down, stop at the nearest safe location, and
adjust the trailer load to eliminate trailer sway.
Hill Start Assist (HSA)The HSA system is designed to assist the driver
when starting a vehicle from a stop on a hill.
HSA will maintain the level of brake pressure
the driver applied for a short period of time after
the driver takes their foot off of the brake pedal.
If the driver does not apply the throttle during
this short period of time, the system will release
brake pressure and the vehicle will roll down the
hill. The system will release brake pressure in
proportion to the amount of throttle applied as
the vehicle starts to move in the intended direc-
tion of travel.HSA Activation Criteria
The following criteria must be met in order for
HSA to activate:
•
Vehicle must be stopped.
• Vehicle must be on a 6% (approximate)
grade or greater hill.
•Gear selection matches vehicle uphill direction
(i.e., vehicle facing uphill is in forward gear;
vehicle backing uphill is in REVERSE gear).
HSA will work in REVERSE and all forward
gears when the activation criteria have been
met. The system will not activate if the vehicle is
placed in NEUTRAL or PARK.
WARNING!
There may be situations on minor hills (i.e.,
less than 8%), with a loaded vehicle, or while
pulling a trailer, when the system will not
activate and slight rolling may occur. This
could cause a collision with another vehicle
or object. Always remember the driver is
responsible for braking the vehicle. Towing With HSA
HSA will provide assistance when starting on a
grade when pulling a trailer.
WARNING!
•
If you use a trailer brake controller with
your trailer, your trailer brakes may be
activated and deactivated with the brake
switch. If so, when the brake pedal is
released, there may not be enough brake
pressure to hold the vehicle and trailer on
a hill and this could cause a collision with
another vehicle or object behind you. In
order to avoid rolling down the hill while
resuming acceleration, manually activate
the trailer brake prior to releasing the
brake pedal. Always remember the driver
is responsible for braking the vehicle.
(Continued)
256

WARNING!(Continued)
•HSA is not a parking brake. If you stop the
vehicle on a hill without putting the trans-
mission in PARK and using the parking
brake, it will roll down the hill and could
cause a collision with another vehicle or
object. Always remember to use the park-
ing brake while parking on a hill, and that
the driver is responsible for braking the
vehicle.
HSA Off
If you wish to turn off the HSA system, it can be
done using the Customer Programmable Fea-
tures in the Electronic Vehicle Information Cen-
ter (EVIC). Refer to “Electronic Vehicle Informa-
tion Center (EVIC)” in “Understanding Your
Instrument Panel” for further information.
Ready Alert BrakingReady Alert Braking may reduce the time re-
quired to reach full braking during emergency
braking situations. It anticipates when an emer-
gency braking situation may occur by monitor-
ing how fast the throttle is released by the driver.
When the throttle is released very quickly,
Ready Alert Braking applies a small amount of
brake pressure. This brake pressure will not be
noticed by the driver. The brake system uses
this brake pressure to allow a fast brake re-
sponse if the driver applies the brakes.
Rain Brake SupportRain Brake Support may improve braking per-
formance in wet conditions. It will periodically
apply a small amount of brake pressure to
remove any water buildup on the front brake
rotors. It only functions when the windshield
wipers are in the LO or HI mode, it does not
function in the intermittent mode. When Rain
Brake Support is active, there is no notification
to the driver and no driver interaction is re-
quired.
Hill Descent Control (HDC) —
Four-Wheel Drive Models With MP3023
Two-Speed Transfer Case Only
HDC maintains vehicle speed while descending
hills during off-road driving situations and is
available in 4WD LOW range only. To enable
HDC, press the HDC switch or put the Selec-
Terrain™ system in “ROCK” mode (“ROCK”
mode is only available in 4WD LOW range).
