trailer JEEP GRAND CHEROKEE 2013 Owner handbook (in English)

WARNING!
You should switch off the ACC system:
•
When driving in fog, heavy rain, heavy snow,
sleet, heavy traffic, and complex driving situ-
ations (i.e., in highway construction zones).
•When entering a turn lane or highway off
ramp; when driving on roads that are wind-
ing, icy, snow-covered, slippery, or have
steep uphill or downhill slopes.
• When towing a trailer up or down steep
slopes.
• When circumstances do not allow safe
driving at a constant speed.
Failure to follow these warnings can result in
a collision and death or serious personal
injury. The Cruise Control system has two control
modes:
•
Adaptive Cruise Control mode for maintaining
an appropriate distance between vehicles.
•Normal (fixed speed) cruise control mode for
cruising at a constant preset speed. For addi-
tional information, refer to “Normal (Fixed
Speed) Cruise Control Mode” in this section.
NOTE:
The system will not react to preceding ve-
hicles. Always be aware of the mode se-
lected.
You can change the mode by using the Cruise
Control buttons. The two control modes function
differently. Always confirm which mode is se-
lected.
Adaptive Cruise Control (ACC)
Operation
The speed control buttons (located on the right
side of the steering wheel) operates the ACC
system.
NOTE:
Any chassis/suspension modifications to
the vehicle will effect the performance of the
Adaptive Cruise Control.

Remove your foot from the accelerator pedal. If
you do not, the vehicle may continue to accel-
erate beyond the set speed. If this occurs:
•The message “DRIVER OVERRIDE” will dis-
play in the EVIC.
• The system will not be controlling the dis-
tance between your vehicle and the vehicle
ahead. The vehicle speed will only be deter-
mined by the position of the accelerator
pedal.To CancelThe system will disable ACC without erasing the
memory if:
•You softly tap the brake pedal.
• You depress the brake pedal.
• You press the CANCEL switch.
• The speed of the vehicle goes below 15 mph
(25 km/h).
• An Anti-Lock Brake System (ABS) event
occurs.
• A Trailer Sway Control (TSC) event occurs.
• The transmission is shifted into NEUTRAL.
• The Electronic Stability Control/Traction Con-
trol System (ESC/TCS) activates.
NOTE:
If ACC is resumed or set with the ESC/TCS
off, ESC will automatically be re-engaged.
To Turn OffThe system will turn off and erase the set speed
in memory if:
• You push the ON/OFF button.

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 nor-
mal 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 installation
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, or a
vehicle merging in from a side lane. There may
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
When driving on a curve with ACC engaged, the
system may decrease the vehicle speed and
acceleration for stability reasons, with no target
vehicle detected. Once the vehicle is out of the
curve the system will resume your original Set
Speed. This is a part of normal ACC system
functionality.
NOTE:
On tight turns ACC performance may be
limited.

•ParkSense®, when on, will MUTE the ra-
dio when it is sounding a tone.
• Clean the ParkSense® sensors regularly,
taking care not to scratch or damage
them. The sensors must not be covered
with ice, snow, slush, mud, dirt or debris.
Failure to do so can result in the system
not working properly. The ParkSense®
system might not detect an obstacle be-
hind or in front of the fascia/bumper, or it
could provide a false indication that an
obstacle is behind or in front of the
fascia/bumper.
•
Objects such as bicycle carriers, trailer
hitches, etc., must not be placed within
12 in (30 cm) from the rear fascia/bumper
while driving the vehicle. Failure to do so
can result in the system misinterpreting a
close object as a sensor problem, causing
the “SERVICE PARK ASSIST SYSTEM”
message to be displayed in the instrument
cluster.
• On vehicles equipped with a tailgate,
ParkSense® should be disabled when the
tailgate is in the lowered or open position.
A lowered tailgate could provide a false
indication that an obstacle is behind the
vehicle.
CAUTION!
•ParkSense® is only a parking aid and it is
unable to recognize every obstacle, includ-
ing small obstacles. Parking curbs might
be temporarily detected or not detected at
all. Obstacles located above or below the
sensors will not be detected when they are
in close proximity.
• The vehicle must be driven slowly when
using ParkSense® in order to be able to
stop in time when an obstacle is detected.
When backing up, it is recommended that
the driver looks over his/her shoulder
when using ParkSense®.
WARNING!
•Drivers must be careful when backing up
even when using the ParkSense® Park
Assist system. Always check carefully be-
hind your vehicle, look behind you, and be
sure to check for pedestrians, animals,
other vehicles, obstructions, and blind
spots before backing up. You are respon-
sible for safety and must continue to pay
attention to your surroundings. Failure to
do so can result in serious injury or death.
• Before using the ParkSense® Park Assist
system, it is strongly recommended that
the ball mount and hitch ball assembly is
disconnected from the vehicle when the
vehicle is not used for towing. Failure to do
so can result in injury or damage to ve-
hicles or obstacles because the hitch ball
will be much closer to the obstacle than the
rear fascia when the warning display turns
on the single flashing arc and sounds the
continuous tone. Also, the sensors could

22. Electronic Vehicle Information Center
(EVIC) Red Telltale Area
This area will display the EVIC reconfigurable
red telltales. For further information, refer to
“Electronic vehicle Information Center (EVIC)”.23. Electronic Stability Control (ESC) OFF
Indicator Light — If Equipped
This light indicates the Electronic
Stability Control (ESC) is off.
24. Vehicle Security Light
This light will flash rapidly for ap-
proximately 15 seconds when the
vehicle theft alarm is arming. The
light will flash at a slower speed
continuously after the alarm is set.
The security light will also come on for about
three seconds when the ignition is first turned on.
25. Temperature Gauge
The temperature gauge shows engine coolant
temperature. Any reading within the normal
range indicates that the engine cooling system
is operating satisfactorily. The gauge pointer will likely indicate a higher
temperature when driving in hot weather, up
mountain grades, or when towing a trailer. It
should not be allowed to exceed the upper limits
of the normal operating range.
CAUTION!
Driving with a hot engine cooling system
could damage your vehicle. If the tempera-
ture gauge reads “H” pull over and stop the
vehicle. Idle the vehicle with the air condi-
tioner turned off until the pointer drops back
into the normal range. If the pointer remains
on the “H” and you hear continuous chimes,
turn the engine off immediately and call an
authorized dealer for service.

Obtain SERVICE IMMEDIATELY. See an autho-
rized dealer.
•If jump starting is required, refer to “Jump
Starting Procedures” in “What To Do In
Emergencies”.
• Electronic Throttle Control (ETC) Light
This light informs you of a problem
with the Electronic Throttle Control
(ETC) system. The light will come
on when the ignition is first turned
ON and remain on briefly as a bulb
check. If the light does not come on during
starting, have the system checked by an autho-
rized dealer.
• If a problem is detected, the light will come on
while the engine is running. Cycle the ignition
key when the vehicle has completely stopped
and the shift lever is placed in the PARK
position. The light should turn off.
• If the light remains lit with the engine running,
your vehicle will usually be drivable. How-
ever, see an authorized dealer for service as soon as possible. If the light is flashing when
the engine is running, immediate service is
required. You may experience reduced per-
formance, an elevated/rough idle or engine
stall and your vehicle may require towing.
• Engine Temperature Warning Light
This light warns of an overheated en-
gine condition. As temperatures rise
and the gauge approaches H,this in-
dicator will illuminate and a single chime will
sound after reaching a set threshold. Further
overheating will cause the temperature gauge
to pass H,a continuous chime will occur until
the engine is allowed to cool.
• If the light turns on while driving, safely pull
over and stop the vehicle. If the A/C system is
on, turn it off. Also, shift the transmission into
NEUTRAL and idle the vehicle. If the tem-
perature reading does not return to normal,
turn the engine off immediately and call for
service. Refer to “If Your Engine Overheats”
in “What To Do In Emergencies” for more
information. •
Transmission Temperature Light
This light indicates that there is
excessive transmission fluid tem-
perature that might occur with se-
vere usage such as trailer towing. It
may also occur when operating the
vehicle in a high torque converter slip condition,
such as 4-wheel-drive operation (e.g., snow
plowing, off- road operation). If this light comes
on, stop the vehicle and run the engine at idle or
faster, with the transmission in NEUTRAL until
the light goes off.
CAUTION!
Continuous driving with the Transmission
Temperature Indicator illuminated will even-
tually cause severe transmission damage or
transmission failure.

Recirculation ControlWhen outside air contains smoke,
odors, or high humidity, or if rapid
cooling is desired, you may wish to
recirculate interior air by pressing
the Recirculation control button.
Recirculation mode should only be
used temporarily. The recirculation LED will
illuminate when this button is selected. Push the
button a second time to turn off the Recircula-
tion mode LED and allow outside air into the
vehicle.
NOTE:
In cold weather, use of Recirculation mode
may lead to excessive window fogging. The
Recirculation mode is not allowed in the
Defrost mode to improve window clearing
operation. Recirculation will be disabled au-
tomatically if this mode is selected.Operating Tips
Window Fogging
Windows will fog on the inside when the humid-
ity inside the vehicle is high. This often occurs in
mild or cool temperatures when it’s rainy or
humid. In most cases, turning the air condition-
ing (pressing the A/C button) on will clear the
fog. Adjust the temperature control, air direc-
tion, and blower speed to maintain comfort.
As the temperature gets colder, it may be
necessary to direct air onto the windshield.
Adjust the temperature control and blower
speed to maintain comfort. Higher blower
speeds will reduce fogging. Interior fogging on
the windshield can be quickly removed by se-
lecting the Defrost mode.
Regular cleaning of the inside of the windows
with a non-filming cleaning solution (vinegar
and water works very well) will help prevent
contaminates (cigarette smoke, perfumes, etc.)
from sticking to the windows. Contaminates
increase the rate of window fogging. Summer Operation
NOTE:
In some cases during high temperature
trailer tow operation the Air Conditioning
system performance may be reduced. This
is to help protect the engine from overheat-
ing during the high load condition.
Your air conditioning system is also equipped
with an automatic recirculation system. When
the system senses a heavy load or high heat
conditions, it may use partial Recirculation A/C
mode to provide additional comfort.
Winter Operation
When operating the system during the winter
months, make sure the air intake, located di-
rectly in front of the windshield, is free of ice,
slush, snow, or other obstructions.
Vacation/Storage
Any time you store your vehicle or keep it out of
service (i.e., vacation) for two weeks or more,
run the air conditioning system at idle for about
five minutes in fresh air with the blower setting
in high. This will ensure adequate system lubri-
cation to minimize the possibility of compressor
damage when the system is started again.

REVERSE
This range is for moving the vehicle backward.
Shift into REVERSE only after the vehicle has
come to a complete stop.
NEUTRAL
Use this range when the vehicle is standing for
prolonged periods with the engine running. The
engine may be started in this range. Apply the
parking brake and shift the transmission into
PARK if you must leave the vehicle.
WARNING!
Do not coast in NEUTRAL and never turn off
the ignition to coast down a hill. These are
unsafe practices that limit your response to
changing traffic or road conditions. You might
lose control of the vehicle and have a collision.
CAUTION!
Towing the vehicle, coasting, or driving for
any other reason with the transmission in
NEUTRAL can cause severe transmission
damage. Refer to “Recreational Towing” in
“Starting And Operating” and “Towing A Dis-
abled Vehicle” in “What To Do In Emergen-
cies” for further information.
DRIVE
This range should be used for most city and
highway driving. It provides the smoothest up-
shifts and downshifts, and the best fuel
economy. The transmission automatically up-
shifts through underdrive first, second, and third
gears, direct fourth gear and overdrive fifth
gear. The DRIVE position provides optimum
driving characteristics under all normal operat-
ing conditions. When frequent transmission shifting occurs
(such as when operating the vehicle under
heavy loading conditions, in hilly terrain, travel-
ing into strong head winds, or while towing
heavy trailers), use the AutoStick® shift control
(refer to “AutoStick®” in this section) to select a
lower gear. Under these conditions, using a
lower gear will improve performance and ex-
tend transmission life by reducing excessive
shifting and heat buildup.
Transmission Limp Home Mode
Transmission function is monitored electroni-
cally for abnormal conditions. If a condition is
detected that could result in transmission dam-
age, Transmission Limp Home Mode is acti-
vated. In this mode, the transmission remains in
direct gear regardless of which forward gear is
selected. PARK, REVERSE, and NEUTRAL will
continue to operate. The Malfunction Indicator
Light (MIL) may be illuminated. Limp Home
Mode allows the vehicle to be driven to an
authorized dealer for service without damaging
the transmission.
