2013 JEEP GRAND CHEROKEE air condition

If the light remains on when the parking brake has been
disengaged, and the fluid level is at the full mark on the
master cylinder reservoir, it indicates a possible brake
hydraulic system malfunction or that a problem with the
Brake Booster has been detected by the Anti-Lock Brake
System (ABS) / Electronic Stability Control (ESC) system.
In this case, the light will remain on until the condition
has been corrected. If the problem is related to the brake
booster, the ABS pump will run when applying the brake
and a brake pedal pulsation may be felt during each stop.
The dual brake system provides a reserve braking capac-
ity in the event of a failure to a portion of the hydraulic
system. A leak in either half of the dual brake system is
indicated by the Brake Warning Light, which will turn on
when the brake fluid level in the master cylinder has
dropped below a specified level.
The light will remain on until the cause is corrected.NOTE:The light may flash momentarily during sharp
cornering maneuvers, which change fluid level condi-
tions. The vehicle should have service performed, and
the brake fluid level checked.
If brake failure is indicated, immediate repair is neces-
sary.
WARNING!
Driving a vehicle with the red brake light on is
dangerous. Part of the brake system may have failed.
It will take longer to stop the vehicle. You could have
a collision. Have the vehicle checked immediately.
Vehicles equipped with the Anti-Lock Brake System
(ABS), are also equipped with Electronic Brake Force
Distribution (EBD). In the event of an EBD failure, the
Brake Warning Light will turn on along with the ABS
Light. Immediate repair to the ABS system is required .

23. Electronic Stability Control (ESC) OFF Indicator
Light — If Equipped
This light indicates the Electronic Stability Con-
trol (ESC) is off.
24. Vehicle Security Light
This light will flash rapidly for approximately
15 seconds when the vehicle theft alarm is
arming. The light will flash at a slower speed
continuously after the alarm is set. The security
light will also come on for about three seconds when the
ignition is first turned on.
25. Temperature Gauge
The temperature gauge shows engine coolant tempera-
ture. Any reading within the normal range indicates that
the engine cooling system is operating satisfactorily.The gauge pointer will likely indicate a higher tempera-
ture when driving in hot weather, up mountain grades,
or when towing a trailer. It should not be allowed to
exceed the upper limits of the normal operating range.
CAUTION!
Driving with a hot engine cooling system could
damage your vehicle. If the 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 an autho-
rized dealer for service.

longerexists. Once driving conditions are safe, then pull
over and let vehicle idle. After 5 minutes, the system will
cool and return to normal operation. Refer to “Power
Steering” in “Starting and Operating” for further
information.
NOTE:
•Even if power steering assistance is no longer opera-
tional, it is still possible to steer the vehicle. Under
these conditions there will be a substantial increase in
steering effort, especially at very low vehicle speeds
and during parking maneuvers.
•If the condition persists, see your authorized dealer for
service.
EVIC Amber Telltale Lights
This area will show reconfigurable amber caution tell-
tales. These telltales include:
•Forward Collision Warning (FCW) OFF
This light warns the driver of a potential colli-
sion with the vehicle in front and prompts the
driver to take action in order to avoid the
collision. For further information, refer to
“Adaptive Cruise Control (ACC)” in “Understanding
The Features Of Your Vehicle.”
•Air Suspension Up
The air suspension up telltale will illuminate
when the air suspension is in use. For further
information, refer to “Starting And Operating”.

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.NOTE:If you experience difficulty in playing a particu-
lar disc, it may be damaged (i.e., scratched, reflective
coating removed, a hair, moisture or dew on the disc)
oversized, or have protection encoding. Try a known
good disc before considering disc player service.
RADIO OPERATION AND MOBILE PHONES
Under certain conditions, the mobile 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 mobile 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 mobile phone operation when
not using Uconnect® (if equipped).4

CLIMATE CONTROLS
The air conditioning and heating system is designed to
make you comfortable in all types of weather.
Dual-Zone Manual Heating And Air Conditioning
The Dual-Zone Manual Climate Controls allow both
driver and front passenger seat occupants to select indi-
vidual comfort settings. The controls consist of a series of
outer rotary dials and inner push knobs.
Blower Control
Rotate this control to regulate the
amount of air forced through the ven-
tilation system in any mode. The
blower speed increases as you move
the control to the right from the “O”
(OFF) position. There are seven blower
speeds.
Manual Temperature Control
418 UNDERSTANDING YOUR INSTRUMENT PANEL

Temperature Controls
•Driver Temperature Control
Rotate this control to regulate the tem-
perature of the air inside the passenger
compartment for the left front seat occu-
pant. Rotating the dial left into the blue
area of the scale indicates cooler tem-
peratures, while rotating right into the
red area indicates warmer temperatures.
•Passenger Temperature Control
Rotate this control to regulate the tem-
perature of the air inside the passenger
compartment for the right front seat oc-
cupant. Rotating the dial left into the blue
area of the scale indicates cooler tem-
peratures, while rotating right into the
red area indicates warmer temperatures.
NOTE:If your air conditioning performance seems
lower than expected, check the front of the A/C con-
denser located in front of the radiator for an accumula-
tion of dirt or insects. Clean with a gentle water spray
from behind the radiator and through the condenser.
Fabric front fascia protectors may reduce airflow to the
condenser, reducing air conditioning performance.
Mode Control (Air Direction)
Push the mode control buttons to choose from several
patterns of air distribution.
Panel
Air is directed through the outlets in the instru-
ment panel. These outlets can be adjusted to direct
airflow.

UNDERSTANDING YOUR INSTRUMENT PANEL 419

NOTE:The center instrument panel outlets can be aimed
so that they are directed toward the rear seat passengers
for maximum airflow to the rear.
Bi-Level
Air is directed through the panel and floor outlets.
NOTE:For all settings, except full cold or full hot, there
is a difference in temperature between the upper and
lower outlets. The warmer air flows to the floor outlets.
This feature gives improved comfort during sunny but
cool conditions.
Floor
Air is directed through the floor outlets with a
small amount flowing through the defrost and
side window demist outlets.Mix
Air is directed through the floor, defrost, and side
window demist outlets. This setting works best in
cold or snowy conditions that require extra heat to the
windshield. This setting is good for maintaining comfort
while reducing moisture on the windshield.
Defrost
Air is directed through the windshield and side
window demist outlets. Use this mode with maxi-
mum blower and temperature settings for best wind-
shield and side window defrosting.
NOTE:
•In Floor, Mix and Defrost modes air will flow through
the outboard panel outlets for occupant comfort. If this
is not desired, the airflow outlet vents can be closed to
stop this.
