2014 JEEP GRAND CHEROKEE maintenance

Sunroof Maintenance
Use only a nonabrasive cleaner and a soft cloth to clean
the glass panel.
Ignition OFF Operation
The power sunroof switches remain active for up to
approximately ten minutes after the ignition switch has
been turned OFF. Opening either front door will cancel
this feature. The time is programmable. Refer to “Elec-
tronic Vehicle Information Center (EVIC)/Personal Set-
tings (Customer-Programmable Features)” in “Under-
standing Your Instrument Panel” for further information.

NOTE:If three consecutive sunroof close attempts result
in Pinch Protect reversals, the fourth close attempt will be
a Manual Close movement with Pinch Protect disabled.
Wind Buffeting
Wind buffeting can be described as the perception of
pressure on the ears or a helicopter-type sound in the
ears. Your vehicle may exhibit wind buffeting with the
windows down, or the sunroof (if equipped) in certain
open or partially open positions. This is a normal occur-
rence and can be minimized. If the buffeting occurs with
the rear windows open, open the front and rear windows
together to minimize the buffeting. If the buffeting occurs
with the sunroof open, adjust the sunroof opening to
minimize the buffeting or open any window.
Sunroof Maintenance
Use only a non-abrasive cleaner and a soft cloth to clean
the glass panel.
Ignition OFF Operation
The power sunroof switches can be programmed to
remain active for up to approximately ten minutes after
the ignition switch has been turned OFF. Refer to “Elec-
tronic Vehicle Information Center (EVIC)/Customer-
Programmable Features (System Setup)” in “Under-
standing Your Instrument Panel” for further information.
NOTE: Opening either front door will cancel this fea-
ture.
Sunroof Fully Closed
Press the switch forward and release to ensure that the
sunroof is fully closed.

As an added safety feature, your vehicle has been
equipped with a Tire Pressure Monitoring System
(TPMS) that illuminates a low tire pressure telltale when
one or more of your tires is significantly under-inflated.
Accordingly, when the low tire pressure telltale illumi-
nates, you should stop and check your tires as soon as
possible, and inflate them to the proper pressure. Driving
on a significantly under-inflated tire causes the tire to
overheat and can lead to tire failure. Under-inflation also
reduces fuel efficiency and tire tread life, and may affect
the vehicle’s handling and stopping ability.
Please note that the TPMS is not a substitute for proper
tire maintenance, and it is the driver ’s responsibility to
maintain correct tire pressure, even if under-inflation has
not reached the level to trigger illumination of the TPMS
low tire pressure telltale.Your vehicle has also been equipped with a TPMS
malfunction indicator to indicate when the system is not
operating properly. The TPMS malfunction indicator is
combined with the low tire pressure telltale. When the
system detects a malfunction, the telltale will flash for
approximately one minute and then remain continuously
illuminated. This sequence will continue upon subse-
quent vehicle start-ups as long as the malfunction exists.
When the malfunction indicator is illuminated, the sys-
tem may not be able to detect or signal low tire pressure
as intended. TPMS malfunctions may occur for a variety
of reasons, including the installation of replacement or
alternate tires or wheels on the vehicle that prevent the
TPMS from functioning properly. Always check the
TPMS malfunction telltale after replacing one or more
tires or wheels on your vehicle, to ensure that the
replacement or alternate tires and wheels allow the TPMS
to continue to function properly.

Radio Operation
Pressing the top of the switch will “Seek” up for the next
listenable station and pressing the bottom of the switch
will “Seek” down for the next listenable station.
The button located in the center of the left-hand control
will tune to the next preset station that you have pro-
grammed in the radio preset pushbutton.
CD Player
Pressing the top of the switch once will go to the next
track on the CD. Pressing the bottom of the switch once
will go to the beginning of the current track, or to the
beginning of the previous track if it is within one second
after the current track begins to play.
If you press the switch up or down twice, it plays the
second track; three times, it will play the third, etc.
CD/DVD DISC MAINTENANCE
To keep a CD/DVD in good condition, take the following
precautions:
1.
Handle the disc by its edge; avoid touching the surface.
2. If the disc is stained, clean the surface with a soft cloth,wiping from center to edge.
3. Do not apply paper or tape to the disc; avoid scratch- ing the disc.
4. Do not use solvents such as benzene, thinner, cleaners, or anti-static sprays.
5. Store the disc in its case after playing.
6. Do not expose the disc to direct sunlight.
7. Do not store the disc where temperatures may become too high.

Operating Tips
NOTE:Refer to the chart at the end of this section for
suggested control settings for various weather conditions.
Summer Operation
The engine cooling system must be protected with a
high-quality antifreeze coolant to provide proper corro-
sion protection and to protect against engine overheating.
A solution of 50% OAT (Organic Additive Technology)
coolant that meets the requirements of Chrysler Material
Standard MS-12106 and 50% water is recommended.
Refer to “Maintenance Procedures” in “Maintaining Your
Vehicle” for proper coolant selection.
Winter Operation
Use of the air Recirculation mode during Winter months is
not recommended because it may cause window fogging.
Vacation Storage
Any time you store your vehicle or keep it out of service
(i.e., vacation) for two weeks or more, run the air
conditioning system at idle for about five minutes in the
fresh air and high blower setting. This will ensure
adequate system lubrication to minimize the possibility
of compressor damage when the system is started again.
Window Fogging
Interior fogging on the windshield can be quickly re-
moved by turning the mode selector to Defrost. The
Defrost/Floor mode can be used to maintain a clear
windshield and provide sufficient heating. If side win-
dow fogging becomes objectionable, increase blower
speed to improve airflow and clearing of the side win-
dows. Vehicle windows tend to fog on the inside in mild
but rainy or humid weather.

NOTE:
•Recirculate without A/C should not be used for long
periods, as fogging may occur.
• Automatic Temperature Controls (ATC) will automati-
cally adjust the climate control settings to reduce or
eliminate window fogging on the front windshield.
When this occurs, recirculation will be unavailable.
Outside Air Intake
Make sure the air intake, located directly in front of the
windshield, is free of obstructions such as leaves. Leaves
collected in the air intake may reduce airflow, and if they
enter the plenum, they could plug the water drains. In
Winter months, make sure the air intake is clear of ice,
slush, and snow.
A/C Air Filter
The climate control system filters outside air containing
dust, pollen and some odors. Strong odors cannot be
totally filtered out. Refer to “Maintenance Procedures”
in “Maintaining Your Vehicle” for filter replacement
instructions.

WARNING!(Continued)
•Failure to equip your vehicle with tires having
adequate speed capability can result in sudden tire
failure and loss of vehicle control.
CAUTION!
Replacing original tires with tires of a different size
may result in false speedometer and odometer read-
ings.
TIRE ROTATION RECOMMENDATIONS
The tires on the front and rear of your vehicle operate at
different loads and perform different steering, handling,
and braking functions. For these reasons, they wear at
unequal rates. These effects can be reduced by timely rotation of tires.
The benefits of rotation are especially worthwhile with
aggressive tread designs such as those on On/Off-Road
type tires. Rotation will increase tread life, help to main-
tain mud, snow, and wet traction levels, and contribute to
a smooth, quiet ride.
Refer to the “Maintenance Schedule” for the proper
maintenance intervals. More frequent rotation is permis-
sible if desired. The reasons for any rapid or unusual
wear should be corrected prior to rotation being per-
formed.
NOTE:
The premium Tire Pressure Monitor System will
automatically locate the pressure values displayed in the
correct vehicle position following a tire rotation.
