2009 JEEP GRAND CHEROKEE heater

When you press the VR button, you will hear a beep. The
beep is your signal to give a command.
NOTE:If you do not say a command within a few
seconds, the system will present you with a list of
options.
If you ever wish to interrupt the system while it lists
options, press the VR button, listen for the beep, and say
your command.
Pressing the VR button while the system is speaking is
known as “barging in.” The system will be interrupted
and after the beep you can add or change commands.
This will become helpful once you start to learn the
options.
NOTE:At any time, you can say the words “Cancel”,
“Help”, or “Main Menu”.These commands are universal and can be used from any
menu. All other commands can be used depending upon
the active application.
For example, if you are in the disc menu and you are
listening to FM radio, you can speak commands from the
disc menu or from the FM radio menu.
When using this system, you should speak clearly and at
a normal speaking volume.
The system will best recognize your speech if the win-
dows are closed, and the heater/air-conditioning fan is
set to low.
At any point, if the system does not recognize one of your
commands, you will be prompted to repeat it.
To hear the first available Menu, press the VR button and
say “Help” or “Main Menu”.

NOTE:The four-way seat does not have an up/down
adjustment.
Head Restraints
Head restraints can reduce the risk of whiplash injury in
the event of impact from the rear. Adjustable head
restraints should be adjusted so that the upper edge is as
High as practical. The head restraints have a locking
button which must be pushed in to lower the head
restraint to all positions. The restraints may be raised
without pushing in the button.
Front Heated Seats — If Equipped
The front driver and passenger seats are heated. The
controls for each heater are located near the bottom
center of the instrument panel (below the heater/air
conditioning controls). The heaters provide the same
average heat level for both the cushion and the seatback.

After turning the ignition ON, you can choose from a
High or Low heat setting. Illuminated LEDs on each
switch indicate the level of heat in use.
Press the switch once to select High-level heat-
ing. Press the switch a second time to select
Low-level heating. Press the switch a third time
to shut the heating elements Off. Two indica-
tors will illuminate for High, one for Low, and none for
Off.
When the High-level setting is selected, the heater will
provide a boosted heat level during the first four minutes
of operation. Then, the heat output will drop to the
normal High-level. If the High-level setting is selected,
the system will automatically switch to Low-level after
approximately 30 minutes of continuous operation. At
that time, the number of illuminated LEDs changes fromtwo to one, indicating the change. The Low-level setting
will turn Off automatically after approximately 30 min-
utes.
NOTE:Once a heat setting is selected, heat will be felt
within two to five minutes.
WARNING!
•Persons who are unable to feel pain to the skin
because of advanced age, chronic illness, diabetes,
spinal cord injury, medication, alcohol use, ex-
haustion or other physical condition must exercise
care when using the seat heater. It may cause burns
even at Low temperatures, especially if used for
long periods of time.

WARNING! (Continued)
•Do not place anything on the seat that insulates
against heat, such as a blanket or cushion. This
may cause the seat heater to overheat. To avoid
heated seat surfaces coming in contact with each
other and potential seat overheating, ALWAYS
ensure that the seat heater is in the Off position
(amber lights indicate High/Low/Off) before plac-
ing any of the seats into a folded flat position (if
equipped).
Rear Heated Seats — If Equipped
On vehicles equipped with rear heated seats, the seats
closest to the doors are heated. The controls for these
seats are located on the rear of the center console.Press the switch once to select High-level heat-
ing. Press the switch a second time to select
Low-level heating. Press the switch a third time
to shut the heating elements Off. Two indica-
tors will illuminate for High, one for Low, and none for

Extremely Cold Weather (Below20°F or29°C)
To ensure reliable starting at these temperatures, use of
an externally powered electric engine block heater (avail-
able from your authorized dealer) is recommended.
If Engine Fails To Start
WARNING!
•Never pour fuel or other flammable liquids into
the throttle body air inlet opening in an attempt to
start the vehicle. This could result in a flash fire
causing serious personal injury.
(Continued)
WARNING! (Continued)
•Do not attempt to push or tow your vehicle to get
it started. Vehicles equipped with an automatic
transmission cannot be started this way. Unburned
fuel could enter the catalytic converter and once
the engine has started, ignite and damage the
converter and vehicle. If the vehicle has a dis-
charged battery, booster cables may be used to
obtain a start from a booster battery or the battery
in another vehicle. This type of start can be dan-
gerous if done improperly. Refer to Section 6 for
proper jump-starting procedures and follow them
carefully.
If the engine fails to start after you have followed the
“Normal Starting” or “Extreme Cold Weather” proce-
dures, it may be flooded. To clear any excess fuel, push
the accelerator pedal all the way to the floor and hold it.
Then, turn the ignition switch to the START position and

Engine Idling - In Cold Weather
Avoid prolonged idling in ambient temperatures below
0°F (-18°C). Long periods of idling may be harmful to
your engine because combustion chamber temperatures
can drop so low that the fuel may not burn completely.
Incomplete combustion allows carbon and varnish to
form on piston rings and injector nozzles. Also, the
unburned fuel can enter the crankcase, diluting the oil
and causing rapid wear to the engine.
Stopping The Engine
Before turning off your turbo diesel engine, always allow
the engine to return to normal idle speed and run for
several seconds. This assures proper lubrication of the
turbocharger. This is particularly necessary after any
period of hard driving.
Idle the engine a few minutes before routine shutdown.
After full load operation, idle the engine three to five
minutes before shutting it down. This idle period willallow the lubricating oil and coolant to carry excess heat
away from the combustion chamber, bearings, internal
components, and turbocharger. This is especially impor-
tant for turbocharged, charge air cooled engines.
ENGINE BLOCK HEATER — IF EQUIPPED
The engine block heater warms the engine, and permits
quicker starts in cold weather. Connect the heater cord to
a ground-fault interrupter protected 110-115 Volt AC
electrical outlet with a grounded, three-wire extension
cord.
Use the heater when temperatures below 0°F (-18°C) are
expected to last for several days.
The block heater must be plugged in at least one hour to
have an adequate warming effect on the coolant.
The engine block heater cord is located:
•3.7L/4.7L Engine — coiled and strapped to the engine
oil dipstick tube.
