2009 JEEP GRAND CHEROKEE climate control

Do not run the engine in a closed garage or in confined
areas any longer than needed to move your vehicle in or
out of the area.
If it is necessary to sit in a parked vehicle with the engine
running, adjust your heating or cooling controls to force
outside air into the vehicle. Set the blower at high speed.
If you are required to drive with the trunk/liftgate open,
make sure that all windows are closed and the climate
control BLOWER switch is set at high speed. DO NOT
use the recirculation mode.
The best protection against carbon monoxide entry into
the vehicle body is a properly maintained engine exhaust
system.
Whenever a change is noticed in the sound of the exhaust
system, when exhaust fumes can be detected inside the
vehicle, or when the underside or rear of the vehicle isdamaged, have a competent mechanic inspect the com-
plete exhaust system and adjacent body areas for broken,
damaged, deteriorated, or mispositioned parts. Open
seams or loose connections could permit exhaust fumes
to seep into the passenger compartment. In addition,
inspect the exhaust system each time the vehicle is raised
for lubrication or oil change. Replace as required.
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.
Front seat belt assemblies must be replaced after a
collision. Rear seat belt assemblies must be replaced after
a collision if they have been damaged (i.e., bent retractor,
torn webbing, etc.). If there is any question regarding belt
or retractor condition, replace the belt.
70 THINGS TO KNOW BEFORE STARTING YOUR VEHICLE

Instrument Panel and Interior Lights
When the multifunction lever is in the parking light,
headlight, or 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.
Dimmer Control
134 UNDERSTANDING THE FEATURES OF YOUR VEHICLE

If the rear wiper is operating when the ignition is turned
OFF, the wiper will automatically return to the “Park”
position if power accessory delay is active. Power acces-
sory delay can be cancelled by opening the door; if this
happens, the rear wiper will stop at its current position
and will not go to “Park”.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.
Rear Window Defroster
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 rear window de-
froster is on. The defroster automatically turns off after
about 10 minutes of operation.

Warning Lamp” comes on when the ignition
switch is turned to the “ON” position. They should go
out with the engine running. If the “ESP/BAS Warning
Lamp” comes on continuously with the engine running,
a malfunction has been detected in either the ESP or the
