2008 JEEP GRAND CHEROKEE climate control

²Do not inhale exhaust gases. They contain carbon
monoxide, a colorless and odorless gas which can kill.
Never run the engine in a closed area, such as a
garage, and never sit in a parked vehicle with the
engine running for a extended period. If the vehicle is
stopped in an open area with engine running for more
than a short period, adjust the ventilation system to
force fresh, outside air into the vehicle.
²Guard against carbon monoxide with proper mainte-
nance. Have the exhaust system inspected every time
the vehicle is raised. Have any abnormal conditions
repaired promptly. Until repaired, drive with all side
windows fully open.
²Always run the climate control in panel or floor mode
when driving with any windows open, even if only
slightly, to help keep fresh air circulating inside ve-
hicle. Otherwise poisonous gases could be drawn into
the vehicle.
Safety Checks You Should Make Inside The
Vehicle
Seat Belts
Inspect the belt system periodically, checking for cuts,
frays and loose parts. Damaged parts must be replaced
immediately. Do not disassemble or modify the system.
Seat belt assemblies must be replaced after an accident if
they have been damaged (bent retractor, torn webbing,
etc.). If there is any question regarding belt or retractor
condition, replace the belt.
Airbag Warning Light
The light should come on and remain on for 6 to 8
seconds as a bulb check when the ignition switch is first
turned on. If the bulb is not lit during starting, have it
replaced. If the light stays on or comes on while driving,
have the system checked by an authorized dealer.
THINGS TO KNOW BEFORE STARTING YOUR VEHICLE 67
2

To Activate
1. Select ªAuto Headlamp Low/High Beams? Ð Low/
High Beam.º Refer to ªEVIC Ð Customer Programmable
Featuresº in Section 4 of this manual.
2. Turn the end of the multi-function control lever to the
A (Auto) headlight position.
3. Push the multi-function control lever away from you
(toward front of vehicle) to engage the high beam mode.
NOTE:This system will not activate until the vehicle is
at or above 20 mph (32 km/h).
To Deactivate
1. Pull back on the muti-function control lever to manu-
ally deactivate the system (normal operation of low
beams).
2. Push back on the multi-function control lever once
again to re-activate the system.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.
Instrument Panel and Interior Lights
When the multi-function control lever is in the parklight,
headlight, or A (Auto) position (if equipped), rotating the
center portion of the lever up and down will increase and
decrease the brightness (dimmer control) of the instru-
ment panel lights. Full daytime brightness on all elec-
tronic displays (odometer, overhead console, radio, and
Automatic Climate Control (if equipped) is obtained by
rotating the center portion of the control to the first
detent above the dimmer range. Rotating the control to
the second detent above the dimmer range turns the
interior lights on. Rotating the control to the ªOffº
(extreme bottom) position disables all the interior lights,

If the liftgate flipper glass is open, connection to the rear
window wiper is interrupted preventing activation of the
rear wiper blade. When the liftgate flipper glass is closed,
the rear wiper switch or the ignition switch needs to be
turned OFF and ON to restart the rear wiper.
Adding Washer Fluid
The fluid reservoir for the windshield washers and the
rear window washer is shared. It is located in the front of
the engine compartment on the passenger side and
should be checked for fluid level at regular intervals. Fill
the reservoir with windshield washer solvent (not radia-
tor antifreeze) and operate the system for a few seconds
to flush out the residual water.
Rear Window Defroster Ð If Equipped
Press this button (located on the Climate Control
panel) to turn on the rear window defroster and
the heated side mirrors (if equipped). An LED in
the button will illuminate to indicate the rearwindow defroster is ON. The defroster automatically
turns off after about 10 minutes of operation.
CAUTION!
To avoid damaging the electrical conductors of the
rear window defroster, do not use scrapers, sharp
instruments, or abrasive window cleaners on the
interior surface of the window.
Labels can be peeled off after soaking with warm
water.

RADIO OPERATION AND CELLULAR PHONES
Under certain conditions, the cellular phone being On in
your vehicle can cause erratic or noisy performance from
your radio. This condition may be lessened or eliminated
by relocating the cellular phone antenna. This condition
is not harmful to the radio. If your radio performance
does not satisfactorily ªclearº by the repositioning of the
antenna, it is recommended that the radio volume be
turned down or off during cellular phone operation.
CLIMATE CONTROLS
Automatic Temperature Control
The Infrared Dual-Zone Climate Control System auto-
matically maintains the interior comfort level desired by
the driver and passenger. This is accomplished by a dual
sun-sensor in the top of the instrument panel, and an
infrared sensor located in the face of the control unit.
There are also various sensors monitored by this system
which take account for vehicle speed, A/C pressure,outside temperature, and engine cooling temperature.
The infrared sensor independently measures the surface
temperature of the driver and passenger. Based on the
sensor input, the system automatically adjusts the air
flow temperature, the air flow volume, and amount of
outside air recirculation. This maintains a comfortable
temperature even under changing conditions.

The air conditioning in this system is automatic.
Pressing this button while in AUTO mode will
cause the LED to flash three times and remain off.
This indicates that the system is in AUTO and requesting
the air conditioning is not necessary.
The system will automatically control recircu-
lation. However, pressing this button will tem-
porarily put the system in recirculation mode.
This can be used when outside conditions such
as smoke, odors, dust, or high humidity are present. This
will cause the LED to illuminate.
NOTE:
²The surface of the climate control panel, and the top
center of the instrument panel should be kept free of
debris due to the climate control sensor's location.
Mud on the windshield may also cause poor operation
of this system.
²To provide you with maximum comfort in the auto-
matic mode, during cold start-ups the blower fan will
remain off until the engine warms up. However, the
fan will engage immediately if the defrost mode is
selected or if you manually select a blower speed.
²Under certain conditions (after the vehicle is turned
off) the climate control system may recalibrate and a
noise may be heard for 20 seconds. This is part of
normal operation.
²Most of the time, when in Automatic operation, you
can temporarily put the system into recirculation
mode by pressing the Recirc button. However, under
certain conditions in automatic the system is blowing
air out of the defrost vents. When these conditions are
present and the Recirc button is pressed the indicator
will flash and remain off. This tells you that you are
unable to go into recirculation mode at this time. If you
would like to go to Recirculation mode, you must first

TIRE QUALITY GRADES
The following describes the tire grading categories estab-
lished by the National highway Traffic Safety Adminis-
tration. The specific grade rating assigned by the tire's
manufacturer in each category is shown on the sidewall
of the tires on your car.
All Passenger Car Tires Must Conform to Federal Safety
Requirements in Addition to These Grades.
Treadwear
The treadwear grade is a comparative rating based on the
wear rate of the tire when tested under controlled con-
ditions on a specified government test course. For ex-
ample, a tire graded 150 would wear one and a half (1
1/2) times as well on the government course as a tire
graded 100. The relative performance of tires depends
upon the actual conditions of their use, however, andmay depart significantly from the norm due to variations
in driving habits, service practices and differences in road
characteristics and climate.
Traction Grades
The traction grades, from highest to lowest, are AA, A, B,
and C. Those grades represent the tire's ability to stop on
wet pavement as measured under controlled conditions
on specified government test surfaces of asphalt and
concrete. A tire marked C may have poor traction perfor-
mance.
WARNING!
The traction grade assigned to this tire is based on
straight-ahead braking traction tests, and does not
include acceleration, cornering, hydroplaning, or
peak traction characteristics.
