service indicator JEEP GRAND CHEROKEE 2012 Owner handbook (in English)

Inflatable Curtain (SABIC), Supplemental Seat-
Mounted Side Air Bags (SAB), and front seat
belt pretensioners, as required, depending on
the severity and type of impact.
Advanced Front Air Bags and Supplemental
Driver Side Knee Air Bag are designed to
provide additional protection by supplementing
the seat belts in certain frontal collisions de-
pending on the severity and type of collision.
Advanced Front Air Bags are not expected to
reduce the risk of injury in rear, or side colli-
sions.
The Advanced Front Air Bags and Supplemen-
tal Driver Side Knee Air Bag will not deploy in all
frontal collisions, including some that may pro-
duce substantial vehicle damage — for ex-
ample, some pole collisions, truck underrides,
and angle offset collisions. On the other hand,
depending on the type and location of impact,
Advanced Front Air Bags may deploy in
crashes with little vehicle front-end damage but
that produce a severe initial deceleration.
The side air bags will not deploy in all side
collisions. Side air bag deployment will depend
on the severity and type of collision.Because air bag sensors measure vehicle de-
celeration over time, vehicle speed and dam-
age by themselves are not good indicators of
whether or not an air bag should have de-
ployed.
Seat belts are necessary for your protection in
all accidents, and also are needed to help keep
you in position, away from an inflating air bag.
The ORC monitors the readiness of the elec-
tronic parts of the air bag system whenever the
ignition switch is in the START or ON/RUN
position. If the key is in the LOCK position, in
the ACC position, or not in the ignition, the air
bag system is not on and the air bags will not
inflate.
The ORC contains a backup power supply
system that may deploy the air bags even if the
battery loses power or it becomes discon-
nected prior to deployment.
Also, the ORC turns on the Air Bag
Warning Light in the instrument
panel for approximately four to
eight seconds for a self-check
when the ignition is first turned to
the ON/RUN position. After the self-check, the Air Bag Warning Light will turn
off. If the ORC detects a malfunction in any part
of the system, it turns on the Air Bag Warning
Light, either momentarily or continuously. A
single chime will sound if the light comes on
again after initial startup.
It also includes diagnostics that will illuminate
the instrument cluster Air Bag Warning Light if a
malfunction is noted that could affect the air
bag system. The diagnostics also record the
nature of the malfunction.
WARNING!
Ignoring the Air Bag Warning Light in your
instrument panel could mean you won’t have
the air bags to protect you in a collision. If the
light does not come on as a bulb check when
the ignition is first turned on, stays on after
you start the vehicle, or if it comes on as you
drive, have an authorized dealer service the
air bag system immediately.

You can use your Uconnect™ Phone to access
a voice mail system or an automated service,
such as a paging service or automated cus-
tomer service. Some services require immedi-
ate response selection. In some instances, that
may be too quick for use of the Uconnect™
Phone.
When calling a number with your Uconnect™
Phone that normally requires you to enter in a
touch-tone sequence on your mobile phone
keypad, you can press the
button and
say the sequence you wish to enter followed by
the word “Send”. For example, if required to
enter your PIN followed with a hash, (3746#),
you can press the
button and say, “3 7 4
6 # Send”. Saying a number, or sequence of
numbers, followed by “Send”, is also to be
used for navigating through an automated cus-
tomer service center menu structure, and to
leave a number on a pager.
You can also send stored Uconnect™ Phone-
book entries as tones for fast and easy access
to voice mail and pager entries. To use this
feature, dial the number you wish to call and
then press the
button and say “Send.”
The system will prompt you to enter the name or number and say the name of the phonebook
entry you wish to send. The Uconnect™ Phone
will then send the corresponding phone num-
ber associated with the phonebook entry, as
tones over the phone.
NOTE:
•
You may not hear all of the tones due to
mobile phone network configurations;
this is normal.
• Some paging and voice mail systems
have system time out settings that are too
short and may not allow the use of this
feature.
Barge In — Overriding Prompts
The “Voice Command” button can be used
when you wish to skip part of a prompt and
issue your voice command immediately. For
example, if a prompt is asking “Would you like
to pair a phone, clear a,” you could press the
button and say, “Pair a Phone” to select
that option without having to listen to the rest of
the voice prompt.
Turning Confirmation Prompts On/Off
Turning confirmation prompts off will stop the
system from confirming your choices (e.g., the Uconnect™ Phone will not repeat a phone
number before you dial it).
•
Press the
button to begin.
• After the “Ready” prompt and the following
beep, say:
“Setup Confirmations Prompts On”
“Setup Confirmations Prompts Off”
Phone And Network Status Indicators
If available on the radio and/or on a premium
display such as the instrument panel cluster,
and supported by your mobile phone, the
Uconnect™ Phone will provide notification to
inform you of your phone and network status
when you are attempting to make a phone call
using Uconnect™ Phone. The status is given
for network signal strength, phone battery
strength, etc.
Dialing Using The Mobile Phone Keypad
You can dial a phone number with your mobile
phone keypad and still use the Uconnect™
Phone (while dialing via the mobile phone
keypad, the user must exercise caution and
take precautionary safety measures). By dial-
ing a number with your paired Bluetooth mo-

INSTRUMENT CLUSTER
DESCRIPTIONS
1. Tachometer
Indicates the engine speed in revolutions per
minute (RPM x 1000).
2. Air Bag Warning LightThis light will turn on for four to
eight seconds as a bulb check
when the ignition switch is first
turned to the ON/RUN position. If
the light is either not on during
starting, stays on, or turns on while
driving, have the system inspected at an au-
thorized dealer as soon as possible. Refer to
“Occupant Restraints” in “Things To Know Be-
fore Starting Your Vehicle” for further informa-
tion.
3. Malfunction Indicator Light (MIL) The Malfunction Indicator Light (MIL)
is part of an onboard diagnostic sys-
tem called OBD II that monitors en-
gine and automatic transmission con-
trol systems. The light will illuminate
when the key is in the ON/RUN position before
engine start. If the bulb does not come on when turning the key from OFF to ON/RUN, have the
condition checked promptly.
Certain conditions, such as a loose or missing
gas cap, poor fuel quality, etc., may illuminate
the light after engine start. The vehicle should
be serviced if the light stays on through several
of your typical driving cycles. In most situa-
tions, the vehicle will drive normally and will not
require towing.
CAUTION!
Prolonged driving with the MIL on could cause
damage to the engine control system. It also
could affect fuel economy and drivability. If the
MIL is flashing, severe catalytic converter
damage and power loss will soon occur. Im-
mediate service is required.
WARNING!
A malfunctioning catalytic converter, as refer-
enced above, can reach higher temperatures
than in normal operating conditions. This can
cause a fire if you drive slowly or park over
flammable substances such as dry plants,
wood, cardboard, etc. This could result in
death or serious injury to the driver, occupants
or others.
4. Electronic Stability Control (ESC)
Activation/Malfunction Indicator Light — If
Equipped The “ESC Activation/Malfunction
Indicator Light” in the instrument
cluster will come on when the igni-
tion switch is turned to the ON/
RUN position. It should go out with
the engine running. If the “ESC
Activation/Malfunction Indicator Light” comes
on continuously with the engine running, a
malfunction has been detected in the ESC
system. If this light remains on after several
ignition cycles, and the vehicle has been driven
several miles (kilometers) at speeds greater
159

13. Seat Belt Reminder LightWhen the ignition switch is first turned
to ON/RUN, this light will turn on for
four to eight seconds as a bulb check.
During the bulb check, if the driver or
front passenger’s seat belt is unbuckled, a
chime will sound. After the bulb check or when
driving, if the driver or front passenger seat belt
remains unbuckled, the Seat Belt Indicator
Light will flash or remain on continuously. Refer
to “Occupant Restraints” in “Things To Know
Before Starting Your Vehicle” for further infor-
mation.
14. Brake Warning Light This light monitors various brake
functions, including brake fluid
level and parking brake applica-
tion. If the brake light turns on it
may indicate that the parking
brake is applied, that the brake
fluid level is low, or that there is a problem with
the anti-lock brake system reservoir.
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 Pro-
gram (ESP) system. In this case, the light will
remain on until the condition has been cor-
rected. 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 capacity 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 conditions. The vehicle should
have service performed, and the brake fluid
level checked.
If brake failure is indicated, immediate repair is
necessary.
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 Elec-
tronic 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 re-
quired.
Operation of the Brake Warning Light can be
checked by turning the ignition switch from the
OFF position to the ON/RUN position. The light
should illuminate for approximately two sec-
onds. The light should then turn off unless the
parking brake is applied or a brake fault is
detected. If the light does not illuminate, have
the light inspected by an authorized dealer.

23. Electronic Stability Control (ESC) OFF
Indicator Light — If EquippedThis light indicates the Electronic
Stability Control (ESC) is off.
24. Vehicle Security Light This light will flash rapidly for ap-
proximately 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
temperature. Any reading within the normal
range indicates that the engine cooling system
is operating satisfactorily.
The gauge pointer will likely indicate a higher
temperature 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 ve-
hicle. 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 authorized
dealership for service.
WARNING!
A hot engine cooling system is dangerous.
You or others could be badly burned by steam
or boiling coolant. You may want to call an
authorized dealership for service if your ve-
hicle overheats. If you decide to look under
the hood yourself, see “Maintaining Your Ve-
hicle”. Follow the warnings under the Cooling
System Pressure Cap paragraph.26. Rear Fog Light Indicator
This indicator will illuminate when the
rear fog lights are on.

•Engine Temperature Warning Light
This light warns of an overheated en-
gine condition. As temperatures rise
and the gauge approaches H,this
indicator will illuminate and a single
chime will sound after reaching a set threshold.
Further overheating will cause the temperature
gauge to pass H,a continuous chime will occur
until the engine is allowed to cool.
If the light turns on while driving, safely pull
over and stop the vehicle. If the A/C system is
on, turn it off. Also, shift the transmission into
NEUTRAL and idle the vehicle. If the tempera-
ture reading does not return to normal, turn the
engine off immediately and call for service.
Refer to “If Your Engine Overheats” in “What To
Do In Emergencies” for more information.
• Transmission Temperature Light
This light indicates that there is
excessive transmission fluid tem-
perature that might occur with se-
vere usage such as trailer towing.
It may also occur when operating
the vehicle in a high torque con-
verter slip condition, such as 4-wheel-drive
operation (e.g., snow plowing, off- road opera- tion). If this light comes on, stop the vehicle and
run the engine at idle or faster, with the trans-
mission in NEUTRAL until the light goes off.
CAUTION!
Continuous driving with the Transmission
Temperature Indicator illuminated will eventu-
ally cause severe transmission damage or
transmission failure.
WARNING!
If the Transmission Temperature Warning
Light is illuminated and you continue operat-
ing the vehicle, in some circumstances you
could cause the fluid to boil over, come in
contact with hot engine or exhaust compo-
nents and cause a fire.
Engine Oil Change Indicator System
Oil Change Due
Your vehicle is equipped with an engine oil
change indicator system. The “Oil Change
Due” message will flash in the EVIC display for
approximately 10 seconds after a single chime
has sounded, to indicate the next scheduled oil
change interval. The engine oil change indica-
tor system is duty cycle based, which means
the engine oil change interval may fluctuate,
dependent upon your personal driving style.
Unless reset, this message will continue to
display each time you turn the ignition switch to
the ON/RUN position or cycle the ignition to the
ON/RUN position if equipped with Keyless
Enter-N-Go. To turn off the message temporar-
ily, press and release the MENU button. To
reset the oil change indicator system (after
performing the scheduled maintenance) refer
to the following procedure.
Vehicles Equipped With Keyless

of which forward gear is selected. PARK, RE-
VERSE, and NEUTRAL will continue to operate.
The Malfunction Indicator Light (MIL) may be
illuminated. Limp Home Mode allows the ve-
hicle to be driven to an authorized dealer for
service without damaging the transmission.
In the event of a momentary problem, the
transmission can be reset to regain all forward
gears by performing the following steps:
1. Stop the vehicle.
2. Shift the transmission into PARK.
3. Turn the ignition switch to the LOCK/OFF
position.
4. Wait approximately 10 seconds.
5. Restart the engine.
6. Shift into the desired gear range. If the
problem is no longer detected, the transmis-
sion will return to normal operation.
NOTE:
Even if the transmission can be reset, we
recommend that you visit your authorized
dealer at your earliest possible conve-nience. Your authorized dealer has diagnos-
tic equipment to determine if the problem
could recur.
If the transmission cannot be reset, authorized
dealer service is required.
Electronic Range Select (ERS) Operation
The Electronic Range Select (ERS) shift control
allows the driver to limit the highest available
gear when the shift lever is in the DRIVE
position. For example, if you shift the transmis-
sion into 3 (third gear), the transmission will
never shift above third gear, but will shift down
into second and first gear normally.
You can switch between DRIVE and ERS mode
at any vehicle speed. When the shift lever is in
the DRIVE position, the transmission will oper-
ate automatically, shifting between all available
gears. Tapping the shift lever to the left (-) will
downshift the transmission, activate ERS mode,
display the current gear in the instrument clus-
ter, and maintain that gear as the top available
gear. Once in ERS mode, tapping the shift lever
to the left (-) or right (+) will change the top
available gear.
To exit ERS mode, simply press and hold the
shift lever to the right (+) until “D” is once again
displayed in the shift lever position indicator in
the instrument cluster.
WARNING!
Do not downshift for additional engine braking
on a slippery surface. The drive wheels could
lose their grip and the vehicle could skid,
causing an accident or personal injury.
