2010 JEEP GRAND CHEROKEE ignition

Headlight DelayTo aid in your exit, your vehicle is equipped with
a headlight delay that will leave the headlights
on for approximately 90 seconds. This delay is
initiated when the ignition is turned OFF while
the headlight switch is on, and then the head-
light switch is cycled off. Headlight delay can
be cancelled by either turning the headlight
switch on then off, or by turning the ignition ON.
The headlight delay time is programmable on
vehicles equipped with an Electronic Vehicle
Information Center (EVIC). Refer to “Electronic
Vehicle Information Center (EVIC)/Customer-
Programmable Features” in “Understanding
Your Instrument Panel” for further information.
Parking Lights and Panel Lights
To turn on the parking lights and instru-
ment panel lights, rotate the headlight
switch clockwise. To turn off the park-
ing lights, rotate the headlight switch back to
the O (Off) position.
Front and Rear Fog Lights —
If Equipped
The front and rear fog lights may be operated
as desired when visibility is poor due to fog.
The fog lights will activate in the following order:
Press the headlight switch once and the front
fog lights come on. Press the switch a second
time and the rear fog lights will come on (front
fog lights stay on). Press the switch a third time
and the rear fog lights turn off (front fog stays
on). Press the switch a fourth times and the
front fog turns off. For vehicles without front fog,
rear fog will activate on the first press.
Interior LightsCourtesy and dome lights are turned on when
the front doors are opened, when the dimmer
control (rotating wheel on the right side of the
headlight switch) is rotated to the its farthest
upward position, or if equipped, when the UN-
LOCK button is pressed on the Remote Keyless
Entry (RKE) transmitter. When a door is open
and the interior lights are on, rotating the dim-
mer control all the way down, to the OFF detent,
will cause all the interior lights to go out. This is
also known as the “Party” mode because it
allows the doors to stay open for extended
periods of time without discharging the vehi-
cle’s battery.
Fog Light Operation

The brightness of the instrument panel lighting
can be regulated by rotating the dimmer con-
trol up (brighter) or down (dimmer). When the
headlights are on you can supplement the
brightness of the odometer, trip odometer, radio
and overhead console by rotating the control to
its farthest position up until you hear a click.
This feature is termed the “Parade” mode and
is useful when headlights are required during
the day.Lights-on ReminderIf the headlights, parking lights, or cargo lights
are left on after the ignition is turned OFF, a
chime will sound when the driver’s door is
opened.
Battery SaverTo protect the life of your vehicle’s battery, load
shedding is provided for both the interior and
exterior lights.
If the ignition is OFF and any door is left ajar for
10 minutes or the dimmer control is rotated all
the way up to the dome ON position for 10 min-
utes, the interior lights will automatically turn off.
If the headlights remain on while the ignition is
cycled OFF, the exterior lights will automatically
turn off after eight minutes. If the headlights are
turned on and left on for eight minutes while the
ignition is OFF, the exterior lights will automati-
cally turn off.
NOTE:
Battery saver mode is cancelled if the igni-
tion is ON.
Front Map/Reading Lights
The front map/reading lights are mounted in the
overhead console.
Each light can be turned on by pressing a
switch on either side of the console. These
buttons are backlit for night time visibility. To
turn the lights off, press the switch a second
time. The lights will also turn on when the
UNLOCK button on the Remote Keyless Entry
(RKE) is pressed.

MistUse the Mist feature when weather conditions
make occasional usage of the wipers neces-
sary. Rotate the end of the lever downward to
the Mist position and release for a single wiping
cycle.
Rain Sensing Wipers — If EquippedThis feature senses moisture on the windshield
and automatically activates the wipers for the
driver. The feature is especially useful for road
splash or overspray from the windshield wash-
ers of the vehicle ahead. Rotate the end of the
multifunction lever to one of four settings to
activate this feature.The sensitivity of the system can be adjusted
with the multifunction lever. Wiper delay posi-
tion 1 is the least sensitive, and wiper delay
position 4 is the most sensitive. Setting 3 should
be used for normal rain conditions. Settings 1
and 2 can be used if the driver desires less
wiper sensitivity. Settings 4 can be used if the
driver desires more sensitivity. Place the wiper
switch in the OFF position when not using the
system.
NOTE:
•
The Rain Sensing feature will not operate
when the wiper switch is in the low or
high-speed position.
• The Rain Sensing feature may not func-
tion properly when ice, or dried salt water
is present on the windshield.
• Use of Rain-X or products containing
wax or silicone may reduce Rain Sensing
performance. •
A customer programmable feature in the
Electronic Vehicle Information Center
(EVIC) allows the Rain Sensing feature to
be turned off. Refer to “Electronic Vehicle
Information Center (EVIC)/Personal Set-
tings (Customer-Programmable Features)”
in “Understanding Your Instrument Panel”
for further information.
The Rain Sensing system has protection fea-
tures for the wiper blades and arms, and will
not operate under the following conditions:
• Low Ambient Temperature — When the
ignition is first turned ON, the Rain Sensing
system will not operate until the wiper switch
is moved, vehicle speed is greater than
0 mph (0 km/h), or the outside temperature is
greater than 32°F (0°C).
• Transmission in NEUTRAL Position —
When the ignition is ON, and the transmis-
sion is in the NEUTRAL position, the Rain
Sensing system will not operate until the
wiper switch is moved, vehicle speed is
greater than 5 mph (8 km/h), or the shift lever
is moved out of the NEUTRAL position.

NOTE:
You can resume ACC from a minimum of
20 mph (32 km/h).
WARNING!
The Resume function should only be used if
traffic and road conditions permit. Resuming a
set speed that is too high or too low for
prevailing traffic and road conditions could
cause the vehicle to accelerate or decelerate
too sharply for safe operation. This could
cause a collision and/or serious injury.
To Vary the Speed SettingWhile ACC is set, you can increase the set
speed by pressing and holding the RES +
button. If the button is continually pressed, the
set speed will continue to increase in 5 mph
(10 km/h) increments until the button is re-
leased. The increase in set speed is reflected in
the EVIC display. Pressing the RES
+button once will result in a
1 mph (2 km/h) increase in set speed. Each
subsequent tap of the button results in an
increase of 1 mph (2 km/h).
While ACC is set, the set speed can be de-
creased by pressing and holding the SET -
button. If the button is continually pressed, the
set speed will continue to decrease in 5 mph
(10 km/h) increments until the button is re-
leased. The decrease in set speed is reflected
in the EVIC display.
Pressing the SET -button once will result in a
1 mph (2 km/h) decrease in set speed. Each
subsequent tap of the button results in a de-
crease of 1 mph (2 km/h).
NOTE:
• When you use the SET - button to decel-
erate, if the engine’s braking power does
not slow the vehicle sufficiently to reach
the set speed, the brake system will auto-
matically slow the vehicle.
• The ACC system can only apply a maxi-
mum of 25% of the vehicle’s braking ca-
pability and will not bring the vehicle to a
complete stop.

To Resume
Press the RES+button and then remove your
foot from the accelerator pedal. The EVIC will
display the last set speed.
To Turn Off
The system will turn off and erase the set speed
in memory if:
• You push and release the ON/OFF button.
• You turn off the ignition.
• You switch off ESC.

If the Cruise Control system is turned off and
reactivated, the system will return to the last
driver setting (ACC or Normal Cruise Control).Forward Collision Warning —
If Equipped
Forward Collision Warning (FCW) warns the
driver of a potential collision with the vehicle in
front of you and prompts the driver to take
action in order to avoid the collision.
FCW monitors the information from the forward
looking sensor as well as the Electronic Brake
Controller (EBC), wheel speed sensors, i.e., to
calculate a probable rear-end collision. When
the system determines that a rear-end collision
is probable a visual warning is displayed on the
EVIC, and an audible warning is also provided.
When the system determines a collision with
the vehicle in front of you is no longer probable,
the warning message will be deactivated.
WARNING!
Forward Collision Warning (FCW) is not in-
tended to avoid a collision on its own. The
driver has the responsibility to avoid a colli-
sion by controlling the vehicle via braking and
steering. Failure to follow this warning could
lead to serious injury or death.
FCW Message
130

Changing FCW status (Forward Alert Timing)The FCW feature can be set to Far, set to Near
or turned Off by changing the Forward Alert
Timing in the Electronic Vehicle Information
Center (EVIC) refer to “Electronic Vehicle Infor-
mation Center (EVIC)” in “Understanding Your
Instrument Panel” for further information. The
FCW Status Off, Near or Far will be displayed in
the EVIC.
The default status of FCW is the “Far” setting,
this allows the system to warn you of a possible
collision with the vehicle in front of you when
you are farther away. This gives you the most
reaction time.Changing the FCW status to the “Near” setting,
allows the system to warn you of a possible
collision with the vehicle in front of you when
you are much closer. This setting provides less
reaction time than the “Far” setting, which al-
lows for a more dynamic driving experience.
Changing the FCW status to “Off” prevents the
system from warning you of a possible collision
with the vehicle in front of you.
NOTE:
In the “Off” setting FCW OFF will be dis-
played in the EVIC.
NOTE:
•
The system will retain the last setting
selected by the driver after ignition shut
down.
• FCW will not react to irrelevant objects
such as overhead objects, ground reflec-
tions, objects not in the path of the car,
stationary objects that are far away, on-
coming traffic, or leading vehicles with
the same or higher rate of speed.
• FCW will be disabled like ACC below with
the unavailable screens.
Display Warnings and Maintenance
“Clean Radar Sensor In Front Of Vehicle”
Warning
The FCW “Clean Radar Sensor In Front Of
Vehicle” warning will display when conditions
temporarily limit system performance. This
most often occurs at times of poor visibility,
such as in snow or heavy rain. The FCW system
may also become temporarily blinded due to
obstructions, such as mud, dirt or ice. In these
cases, the EVIC will display “Clean Radar Sen-
sor In Front Of Vehicle” and the system will
deactivate.
Example Only
FCW Off Example

FCW 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 FCW functionality. Although the vehicle is
still drivable under normal conditions, FCW will
be temporarily unavailable. If this occurs, try
activating FCW again later, following a key
cycle. If the problem persists, see your autho-
rized dealer.
Service FCW 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.
PARKSENSEPARK ASSIST —
IF EQUIPPED
The ParkSense Park Assist system provides
visual and audible indications of the distance
between the rear and/or front fascia and a
detected obstacle when backing up or moving forward, e.g. during a parking maneuver. Refer
to ParkSense
System Usage Precautions for
limitations of this system and recommenda-
tions.
ParkSense will retain the last system state
(enabled or disabled) from the last ignition
cycle when the ignition is changed to the
ON/RUN position. ParkSense can be active
only when the shift lever is in REVERSE or
DRIVE.
If ParkSense is enabled at one of these shift
lever positions, the system will remain active
until the vehicle speed is increased to approxi-
mately 11 mph (18 km/h) or above. The system
will become active again if the vehicle speed is
decreased to speeds less than approximately
10 mph (16 km/h).
