2011 JEEP GRAND CHEROKEE fuel type

pending on the severity and type of collision. In
these events, the ORC will deploy the SABIC
only on the impact side of the vehicle.
A quantity of non-toxic gas is generated to
inflate the side curtain airbag. The inflating side
curtain airbag pushes the outside edge of the
headliner out of the way and covers the win-
dow. The airbag inflates in about 30 ms (about
one-quarter of the time that it takes to blink your
eyes) with enough force to injure you if you are
not belted and seated properly, or if items are
positioned in the area where the side curtain
airbag inflates. This especially applies to chil-
dren. The side curtain airbag is only about
3-1/2 in (9 cm) thick when it is inflated.
Because airbag sensors estimate deceleration
over time, vehicle speed and damage are not
good indicators of whether or not an airbag
should have deployed.
NOTE:
In a rollover the pretensioners, and/or SAB
and SABIC airbags 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. Additional sensors in
the ORC determine the level of airbag deploy-
ment and provide verification.
Enhanced Accident Response System
In the event of an impact causing airbag de-
ployment, 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 Airbags are designed to
deflate immediately after deployment.
NOTE:
Front and/or side airbags will not deploy in
all collisions. This does not mean some-
thing is wrong with the airbag system.
If you do have a collision which deploys the
airbags, any or all of the following may occur:
•
The nylon airbag 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.

11. Tire Pressure Monitoring Telltale LightEach tire, including the spare (if
provided), should be checked
monthly, when cold and inflated to
the inflation pressure recom-
mended by the vehicle manufac-
turer on the vehicle placard or tire
inflation pressure label. (If your vehicle has tires
of a different size than the size indicated on the
vehicle placard or tire inflation pressure label,
you should determine the proper tire inflation
pressure for those tires.)
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 thereplacement 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. Position Light Indicator — If Equipped This indicator will illuminate when
the park lights or headlights are
turned on.

•Press the ENGINE START/STOP button a
second time to change the ignition switch to
the RUN position (EVIC displays “IGNITION
MODE RUN”),
• Press the ENGINE START/STOP button a
third time to return the ignition switch to the
OFF position (EVIC displays “IGNITION
MODE OFF”).
Extreme Cold Weather
(Below 20°F or 29°C)
To ensure reliable starting at these tempera-
tures, use of an externally powered electric
engine block heater (available from your autho-
rized 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 per-
sonal 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 discharged
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 dangerous if done improperly. Refer
to “Jump Starting” in “What To Do In Emer-
gencies” for further information.
Clearing a Flooded Engine
(Using ENGINE START/STOP Button)
If the engine fails to start after you have fol-
lowed the “Normal Starting” or “Extreme Cold
Weather procedures, it may be flooded. To
clear any excess fuel, press and hold the brake
pedal, push the accelerator pedal all the way to
the floor and hold it, then press and release the
ENGINE START/STOP button once. The starter
motor will engage automatically, run for 10 sec- onds, and then disengage. Once this occurs,
release the accelerator pedal and the brake
pedal, wait 10 to 15 seconds, then repeat the
“Normal Starting” procedure.
Clearing A Flooded Engine
(Using Fob With Integrated Key)
If the engine fails to start after you have fol-
lowed the “Normal Starting” or “Extreme Cold
Weather” procedures, 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 release it as soon as the starter engages.
The starter motor will disengage automatically
in 10 seconds. Once this occurs, release the
accelerator pedal, turn the ignition switch to the
LOCK position, wait 10 to 15 seconds, then
repeat the “Normal Starting” procedure.
CAUTION!
To prevent damage to the starter, wait 10 to
15 seconds before trying again.
After StartingThe idle speed is controlled automatically and it
will decrease as the engine warms up.

The TPMS will continue to warn the driver of low
tire pressure as long as the condition exists,
and will not turn off until the tire pressure is at or
above recommended cold tire pressure. Once
the “TPM Telltale Light” and the “TIRE LOW
PRESSURE” message appears, the tire pres-
sure must be increased to the recommended
cold tire pressure in order for the ”TPM Telltale
Light” and the “TIRE LOW PRESSURE” mes-
sage to be turned off. The system will automati-
cally update and the “TPM Telltale Light” and
the “TIRE LOW PRESSURE” message will turn
off once the updated tire pressures have been
received. The vehicle may need to be driven for
up to 20 minutes above 15 mph (24 km/h) to
receive this information.
For example, your vehicle has a recommended
cold (parked for more than three hours) tire
pressure of 33 psi (227 kPa). If the ambient
temperature is 68°F (20°C) and the measured
tire pressure is 28 psi (193 kPa), a temperature
drop to 20°F (-7°C) will decrease the tire pres-
sure to approximately 24 psi (165 kPa). This tire
pressure is sufficiently low enough to display
the “TPM Telltale Light” and the “TIRE LOW
PRESSURE” message. Driving the vehicle maycause the tire pressure to rise to approximately
28 psi (193 kPa), but the “TPM Telltale Light”
and the “TIRE LOW PRESSURE” message will
still display. In this situation, the “TPM Telltale
Light” and the “TIRE LOW PRESSURE” mes-
sage will turn OFF only after the tires have been
inflated to the vehicle’s recommended cold tire
pressure value.
CAUTION!
•
The TPMS has been optimized for the
original equipment tires and wheels. TPMS
pressures have been established for the
tire size equipped on your vehicle. Unde-
sirable system operation or sensor damage
may result when using replacement equip-
ment that is not of the same size, type,
and/or style. Aftermarket wheels can cause
sensor damage. Do not use aftermarket tire
sealants or balance beads if your vehicle is
equipped with a TPMS, as damage to the
sensors may result.
(Continued)
CAUTION!(Continued)
• After inspecting or adjusting the tire pres-
sure always reinstall the valve stem cap.
This will prevent moisture and dirt from
entering the valve stem, which could dam-
age the Tire Pressure Monitoring Sensor.
NOTE:
• The TPMS is not intended to replace nor-
mal tire care and maintenance, or to pro-
vide warning of a tire failure or condition.
• The TPMS should not be used as a tire
pressure gauge while adjusting your tire
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.
• The TPMS is not a substitute for proper
tire maintenance, and it is the driver’s
responsibility to maintain correct tire
pressure using an accurate tire gauge,
even if under-inflation has not reached

Loose Fuel Filler Cap Message
If the vehicle diagnostic system
determines that the fuel filler cap is
loose, improperly installed, or
damaged, a loose gascap indica-
tor will display in the EVIC telltale
display area. Refer to “Electronic
Vehicle Information Center (EVIC)” in “Under-
standing Your Instrument Panel” for further in-
formation. Tighten the fuel filler cap properly
and press the SELECT button to turn off the
message. If the problem continues, the mes-
sage will appear the next time the vehicle is
started.
TRAILER TOWINGIn this section you will find safety tips and
information on limits to the type of towing you
can reasonably do with your vehicle. Before
towing a trailer, carefully review this information
to tow your load as efficiently and safely as
possible.
To maintain warranty coverage, follow the re-
quirements and recommendations in this
manual concerning vehicles used for trailer
towing.
Common Towing DefinitionsThe following trailer towing related definitions
will assist you in understanding the following
information.
Gross Vehicle Weight Rating (GVWR)
The GVWR is the total allowable weight of your
vehicle. This includes driver, passengers,
cargo and trailer tongue weight. The total load
must be limited so that you do not exceed the
GVWR.
Gross Trailer Weight (GTW)
The GTW is the weight of the trailer plus the
weight of all cargo, consumables and equip-
ment (permanent or temporary) loaded in or on
the trailer in its loaded and ready for operation 
condition.
The recommended way to measure GTW is to
put your fully loaded trailer on a vehicle scale.
The entire weight of the trailer must be sup-
ported by the scale.
Gross Combination Weight Rating (GCWR)
The GCWR is the total permissible weight of
your vehicle and trailer when weighed in com-
bination. NOTE:
The GCWR rating includes a 150 lbs (68 kg)
allowance for the presence of a driver.
Gross Axle Weight Rating (GAWR)
The GAWR is the maximum capacity of the front
and rear axles. Distribute the load over the front
and rear axles evenly. Make sure that you do
not exceed either front or rear GAWR.
WARNING!
It is important that you do not exceed the
maximum front or rear GAWR. A dangerous
driving condition can result if either rating is
exceeded. You could lose control of the ve-
hicle and have an accident.
Trailer Tongue Weight (TW)
The TW is the downward force exerted on the
hitch ball by the trailer. In most cases it should
not be more than 5% of the trailer load. You
must consider this as part of the load on your
vehicle.
