2005 JEEP GRAND CHEROKEE climate control

A new engine may consume some oil during its first few
thousand miles (kilometers) of operation. This should be
considered as a normal part of the break-in and not
interpreted as an indication of difficulty.
SAFETY TIPS
Exhaust Gas
WARNING!
Exhaust gases can injure or kill. They contain carbon
monoxide (CO) which is colorless and odorless.
Breathing it can make you unconscious and can
eventually poison you. To avoid breathing (CO)
follow the safety tips below.
•Do 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.
•Guard 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.
•Always 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.
64 THINGS TO KNOW BEFORE STARTING YOUR VEHICLE

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 on the windshield
or camera lens will cause the system to function improp-
erly.
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 “Off”
(extreme bottom) position disables all the interior lights,even when the doors and liftgate are open. While in the
“Off” position the instrument panel lighting is at the
lowest light level and may not be suitable for night
driving.
Daytime Running Lights — Canada Only
The headlights come on at a low intensity level whenever
the engine is running. The lights remain on until the
ignition switch is turned OFF or the parking brake is
engaged. The headlight switch must be used for normal
night time driving.
Lights-On Reminder
If the headlights or parking lights are on after the ignition
is turned OFF, a chime will sound when the driver’s door
is opened.

WARNING!
Tilting the steering wheel column while the vehicle
is moving is dangerous. Without a stable steering
column, you could lose control of the vehicle and
have an accident. Adjust the tilting mechanism only
while the vehicle is stopped. Be sure it is locked
before driving.
TRACTION CONTROL — IF EQUIPPED
The Traction Control System monitors the amount of
wheel spin in each of the driven wheels. If wheel spin is
detected, the pressure to the brake system of the slipping
wheel(s) is modulated to provide enhanced acceleration.
The system operates at speeds typically encountered in
city traffic driving. 4WD models also include unique
logic in 4 HI or 4 LO (if equipped) to enhance off-road
capabilities.The “Traction Control Indicator Light,” located in the
instrument cluster, will flash when the Traction Control
System is active.
To turn the system OFF, press the switch, located below
the climate controls in the center stack, until the “Traction
Control Indicator Light” turns on and stays on. Also, a

To turn the ESP system OFF, press the switch, located
below the climate controls in the center stack, until the
ESP Indicator Lightin the instrument cluster turns on
and the messageESP SYSTEM DISABLEDappears in
the Electronic Vehicle Information Center (EVIC). Refer
to Section 4 of this manual. To turn the system back ON,
press the switch a second time until theESP Indicator
Lightturns off. ESP is always available during braking
(in 4WD Hi) even if it has been switched off.
When the ESP system has been switched off, a feature of
the system remains active. This feature functions similar
to a limited slip differential and controls the wheel spin
across an axle. If one wheel on an axle is spinning faster

CAUTION!
Driving with a hot engine cooling system could
damage your vehicle. If temperature gauge reads (H),
pull over and stop the vehicle. Idle the vehicle with
the air conditioner 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 for service.
WARNING!
A hot engine cooling system is dangerous. You or
others could be badly burned by steam or boiling
coolant. If you decide to look under the hood your-
self, refer to Section 7 of this manual. Follow the
warnings under “Cooling System Pressure Cap.”
14. Electronic Vehicle Information Center Display
When the appropriate conditions exist, this display
shows the Electronic Vehicle Information Center (EVIC)
messages. Refer to “Electronic Vehicle Information Cen-
ter” later in this section. (See page 171 for more informa-
tion.)
15. TOW/HAUL Indicator Light
This light will illuminate when the TOW/
HAUL button has been selected. The TOW/
HAUL button is located in the center of the
instrument panel (below the climate controls).
16. 4WD LOW Mode Indicator Light — If Equipped
This light alerts the driver that the vehicle is in
the 4WD LOW mode. The front and rear drive-
shafts are mechanically locked together forcing
the front and rear wheels to rotate at the same
speed. (See page 239 for more information.)

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 “clear” by the repositioning of the
antenna, it is recommended that the radio volume be
turned down or off during cellular phone operation.
CLIMATE CONTROLS
Climate Controls — Manual
Air Conditioning
The controls for the heating/air conditioning and venti-
lation system in this vehicle consist of a series of rotary
knobs. These comfort controls can be set to obtain desired
interior conditions.The instrument panel features four dual-vane airflow
registers. Two registers are located on the outer ends of
the instrument panel and two are located in the center of
the instrument panel. These registers can be closed to
partially block airflow.

Automatic Temperature Control — If Equipped
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.Operation of the system is quite simple. Begin by turning
the right mode knob to AUTO, and place the blower
control (left knob) to either LO AUTO or HI AUTO. The
LO AUTO position should be used for front seat occu-
pants only. The HI AUTO position should be used when
more air flow is desired, or when rear seat occupants are
