2012 JEEP GRAND CHEROKEE fuel

especially applies to children. The side curtain
air bag is only about 3-1/2 in (9 cm) thick when
it is inflated.
Because air bag sensors estimate deceleration
over time, vehicle speed and damage are not
good indicators of whether or not an air bag
should have deployed.
NOTE:
In a rollover the pretensioners, and/or SAB
and SABIC air bags may deploy on both
sides of the vehicle.
Front And Side Impact Sensors
In front and side impacts, impact sensors can
aid the ORC in determining appropriate re-
sponse to impact events.
Enhanced Accident Response System
In the event of an impact causing air bag
deployment, if the communication network re-
mains intact, and the power remains intact,
depending on the nature of the event the ORC
will determine whether to have the Enhanced
Accident Response System perform the follow-
ing functions:
•Cut off fuel to the engine. •
Flash hazard lights as long as the battery
has power or until the ignition key is turned
off.
• Turn on the interior lights, which remain on as
long as the battery has power or until the
ignition key is removed.
• Unlock the doors automatically.
If A Deployment Occurs
The Advanced Front Air Bags are designed to
deflate immediately after deployment.
NOTE:
Front and/or side air bags will not deploy in
all collisions. This does not mean some-
thing is wrong with the air bag system.
If you do have a collision which deploys the air
bags, any or all of the following may occur:
• The nylon air bag material may sometimes
cause abrasions and/or skin reddening to
the driver and front passenger as the air
bags deploy and unfold. The abrasions are
similar to friction rope burns or those you
might get sliding along a carpet or gymna-
sium floor. They are not caused by contact
with chemicals. They are not permanent and normally heal quickly. However, if you
haven’t healed significantly within a few
days, or if you have any blistering, see your
doctor immediately.
• As the air bags deflate, you may see some
smoke-like particles. The particles are a nor-
mal by-product of the process that gener-
ates the non-toxic gas used for air bag
inflation. These airborne particles may irri-
tate the skin, eyes, nose, or throat. If you
have skin or eye irritation, rinse the area with
cool water. For nose or throat irritation, move
to fresh air. If the irritation continues, see your
doctor. If these particles settle on your cloth-
ing, follow the garment manufacturer’s in-
structions for cleaning.
Do not drive your vehicle after the air bags have
deployed. If you are involved in another colli-
sion, the air bags will not be in place to protect
you.

Periodic Safety Checks You Should
Make Outside The Vehicle
Tires
Examine tires for excessive tread wear and
uneven wear patterns. Check for stones, nails,
glass, or other objects lodged in the tread or
sidewall. Inspect the tread for cuts and cracks.
Inspect sidewalls for cuts, cracks and bulges.
Check the wheel nuts for tightness. Check the
tires (including spare) for proper cold inflation
pressure.Lights
Have someone observe the operation of exte-
rior lights while you work the controls. Check
turn signal and high beam indicator lights on
the instrument panel.
Door Latches
Check for positive closing, latching, and lock-
ing.
Fluid Leaks
Check area under vehicle after overnight park-
ing for fuel, engine coolant, oil, or other fluid
leaks. Also, if gasoline fumes are detected or if
fuel, power steering fluid, or brake fluid leaks
are suspected, the cause should be located
and corrected immediately.

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

As an added safety feature, your vehicle has
been equipped with a Tire Pressure Monitoring
System (TPMS) that illuminates a low tire pres-
sure telltale when one or more of your tires is
significantly under-inflated. Accordingly, when
the low tire pressure telltale illuminates, you
should stop and check your tires as soon as
possible, and inflate them to the proper pres-
sure. 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 approxi-
mately one minute and then remain continu-
ously illuminated. This sequence will continue
upon subsequent vehicle start-ups as long as
the malfunction exists. When the malfunction
indicator is illuminated, the system 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.CAUTION!
The TPMS has been optimized for the original
equipment tires and wheels. TPMS pressures
and warning have been established for the tire
size equipped on your vehicle. Undesirable
system operation or sensor damage may re-
sult when using replacement equipment that
is not of the same size, type, and/or style.
Aftermarket wheels can cause sensor dam-
age. Do not use tire sealant from a can or
balance beads if your vehicle is equipped with
a TPMS, as damage to the sensors may
result.
12. Park/Headlight ON Indicator — If
Equipped This indicator will illuminate when
the park lights or headlights are
turned on.
161

The light also will turn on when the parking
brake is applied with the ignition switch in the
ON/RUN position.
NOTE:
This light shows only that the parking brake
is applied. It does not show the degree of
brake application.
15. Anti-Lock Brake (ABS) LightThis light monitors the Anti-Lock
Brake System (ABS). The light will
turn on when the ignition switch is
turned to the ON/RUN position and
may stay on for as long as four
seconds.
If the ABS light remains on or turns on while
driving, it indicates that the Anti-Lock portion of
the brake system is not functioning and that
service is required. However, the conventional
brake system will continue to operate normally
if the BRAKE warning light is not on.
If the ABS light is on, the brake system should
be serviced as soon as possible to restore the
benefits of Anti-Lock brakes. If the ABS light
does not turn on when the ignition switch is turned to the ON/RUN position, have the light
inspected by an authorized dealer.
16. 4 LOW
This light alerts the driver that the
vehicle is in the four-wheel drive
LOW mode. The front and rear
driveshafts are mechanically
locked together forcing the front
and rear wheels to rotate at the
same speed. Low range provides a greater
gear reduction ratio to provide increased
torque at the wheels.
For further information on four-wheel drive op-
eration and proper use, refer to “Four-Wheel
Drive Operation — If Equipped” in “Starting
And Operating”.
17. Speedometer
Indicates vehicle speed.
18. Fuel Door Reminder The fuel pump symbol points to the
side of the vehicle where the fuel
door is located. 19. Fuel Gauge
The pointer shows the level of fuel in the fuel
tank when the ignition switch is in the ON/RUN
position.
20. Electronic Vehicle Information Center
(EVIC) White Telltale Area
This area will display the EVIC reconfigurable
white telltales. For further information, refer to
“Electronic vehicle Information Center (EVIC)”.
21. Electronic Vehicle Information Center
(EVIC) Amber Telltale Area
This area will display the EVIC reconfigurable
amber caution telltales. For further information,
refer to “Electronic vehicle Information Center
(EVIC)”.
22. Electronic Vehicle Information Center
(EVIC) Red Telltale Area
This area will display the EVIC reconfigurable
red telltales. For further information, refer to
