automatic transmission JEEP GRAND CHEROKEE 2010 Owner handbook (in English)

NOTE:
Broken, muddy, or obstructed headlights
and taillights of vehicles in the field of view
will cause headlights to remain on longer
(closer to the vehicle). Also, dirt, film, and
other obstructions (sticker, toll box, etc.) on
the windshield or camera lens will cause the
system to function improperly.
Daytime Running Lights —
If Equipped
The Daytime Running Lights (low intensity)
come on whenever the engine is running, and
the transmission is not in the PARK position.
The lights will remain on until the ignition is
switched to the OFF or ACC position or the
parking brake is engaged. The headlight
switch must be used for normal nighttime driv-
ing.
Disabling the Daytime Running Lights
To disable the Daytime Running Lights open
the hood and located the Power Distribution
Center (PDC), located on the right side of the
engine compartment.Open the PDC by pulling outward on the lock-
ing tabs (one on each side) and pulling upward
on the cover.Remove the left and right Daytime Running
Lamp relays and reinstall the PDC cover.
Automatic Headlight Leveling — HID
Headlights Only
This feature prevents the headlights from inter-
fering with the vision of oncoming drivers.
Headlight leveling automatically adjusts the
height of the headlight beam in reaction to
changes in vehicle pitch.

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.

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).
To decrease speed while the Electronic Speed
Control is set, push the SET (-) button. If the
button is continually held in the SET (-) position,
the set speed will continue to decrease until the
button is released. Release the button when the
desired speed is reached, and the new set
speed will be established.
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).
To Accelerate for PassingPress the accelerator as you would normally.
When the pedal is released, the vehicle will
return to the set speed.Using Electronic Speed Control On Hills
The transmission may downshift on hills to
maintain the vehicle set speed.
NOTE:
The Electronic Speed Control system main-
tains speed up and down hills. A slight
speed change on moderate hills is normal.
On steep hills, a greater speed loss or gain may
occur so it may be preferable to drive without
Electronic Speed Control.
WARNING!
Electronic Speed Control can be dangerous
where the system cannot maintain a constant
speed. Your vehicle could go too fast for the
conditions, and you could lose control and
have a collision. Do not use Electronic Speed
Control in heavy traffic or on roads that are
winding, icy, snow-covered or slippery.
ADAPTIVE CRUISE CONTROL
(ACC) — IF EQUIPPED
Adaptive Cruise Control (ACC) increases the
driving convenience provided by cruise control
while traveling on highways and major road-
ways. However, it is not a safety system and not
designed to prevent collisions.
ACC will allow you to keep cruise control en-
gaged in light to moderate traffic conditions
without the constant need to reset your cruise
control. ACC utilizes a radar sensor designed
to detect a vehicle directly ahead of you.
NOTE:
•
If the sensor does not detect a vehicle
ahead of you, ACC will maintain a fixed
set speed.
• If the ACC sensor detects a vehicle ahead,
ACC will apply limited braking or accel-
eration (not to exceed the original Set
Speed) automatically to maintain a preset
following distance, while matching the
speed of the vehicle ahead.

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.
Activating Adaptive Cruise Control
(ACC)
You can only activate ACC if the vehicle speed
is above 25 mph (40 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.”

INSTRUMENT CLUSTER
DESCRIPTIONS
1. Tachometer
Indicates the engine speed in revolutions per
minute (RPM).
2. Airbag Warning Light
This light will turn on for four to eight
seconds as a bulb check when the
ignition switch is first turned to the
ON/RUN position. If the light is ei-
ther not on during starting, stays on,
or turns on while driving, then have
the system inspected at an authorized dealer as
soon as possible. Refer to “Occupant Re-
straints” in “Things To Know Before Starting Your
Vehicle” for further information.
3. Malfunction Indicator Light (MIL) The Malfunction Indicator Light (MIL)
is part of an onboard diagnostic sys-
tem called OBD II that monitors en-
gine and automatic transmission con-
trol systems. The light will illuminate
when the key is in the ON/RUN position before
engine start. If the bulb does not come on when turning the key from OFF to ON/RUN, have the
condition checked promptly.
Certain conditions such as a loose or missing
gas cap, poor fuel quality, etc., may illuminate
the light after engine start. The vehicle should
be serviced if the light stays on through several
of your typical driving cycles. In most situa-
tions, the vehicle will drive normally and will not
require towing.
CAUTION!
Prolonged driving with the MIL on could cause
damage to the engine control system. It also
could affect fuel economy and drivability. If the
MIL is flashing, severe catalytic converter
damage and power loss will soon occur. Im-
mediate service is required.
WARNING!
A malfunctioning catalytic converter, as refer-
enced above, can reach higher temperatures
than in normal operating conditions. This can
cause a fire if you drive slowly or park over
flammable substances such as dry plants or
wood or cardboard, etc. This could result in
death or serious injury to the driver, occupants
or others.
