2010 JEEP GRAND CHEROKEE fuel cap

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.

ONBOARD DIAGNOSTIC SYSTEM –
OBD II
Your vehicle is equipped with a sophisticated
onboard diagnostic system called OBD II. This
system monitors the performance of the emis-
sions, engine, and automatic transmission con-
trol systems. When these systems are operat-
ing properly, your vehicle will provide excellent
performance and fuel economy, as well as
engine emissions well within current govern-
ment regulations.
If any of these systems require service, the
OBD II system will turn on the “Malfunction
Indicator Light” (MIL). It will also store diagnos-
tic codes and other information to assist your
service technician in making repairs. Although
your vehicle will usually be drivable and not
need towing, see your authorized dealer for
service as soon as possible.
CAUTION!
•Prolonged driving with the MIL on could
cause further damage to the emission con-
trol system. It could also affect fuel
economy and drivability. The vehicle must
be serviced before any emissions tests can
be performed.
• If the MIL is flashing while the engine is
running, severe catalytic converter damage
and power loss will soon occur. Immediate
service is required.
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.
A loose, improperly installed, or damaged fuel
filler cap may also turn on the Malfunction
Indicator Light (MIL).
REPLACEMENT PARTSUse of genuine MOPAR
parts for normal/
scheduled maintenance and repairs is highly
recommended to ensure the designed perfor-
mance. Damage or failures caused by the use
of non-MOPAR parts for maintenance and
repairs will not be covered by the manufactur-
er’s warranty.
MAINTENANCE PROCEDURESThe pages that follow contain the required
maintenance services determined by the engi-
neers who designed your vehicle.
Besides those maintenance items specified in
the fixed maintenance schedule, there are
other components which may require servicing
or replacement in the future.
273

CAUTION!
Do not use chemical flushes in your engine oil
as the chemicals can damage your engine.
Such damage is not covered by the New
Vehicle Limited Warranty.
Engine Oil Selection – ACEA Categories
For countries that use the ACEA European Oil
Categories for Service Fill Oils, use engine oils
that meet the requirements of ACEA C3, and
that are approved to MB 229.31 or MB 229.51.
Engine Oil Viscosity – 3.6L Engine
SAE 5W-30 engine oil is recommended for all
operating temperatures. This engine oil im-
proves low temperature starting and vehicle
fuel economy.
The engine oil filler cap also shows the recom-
mended engine oil viscosity for your vehicle.
For information on engine oil filler cap location,
refer to “Engine Compartment” in “Maintaining
Your Vehicle” for further information. Engine Oil Viscosity – 5.7L Engine
SAE 5W-20 engine oil is recommended for all
operating temperatures. This engine oil im-
proves low temperature starting and vehicle
fuel economy.
The engine oil filler cap also shows the recom-
mended engine oil viscosity for your vehicle.
For information on engine oil filler cap location,
refer to “Engine Compartment” in “Maintaining
Your Vehicle” for further information.
NOTE:
SAE 5W-30 engine oil approved to MB
229.31 or MB 229.51 may be used when SAE
5W-20 engine oil is not available.
Engine Oil – Diesel Engine
Engine Oil Selection
For best performance and maximum protection
under all types of operating conditions, the
manufacturer recommends engine oils that
meet the requirements of Chrysler Material
Standard MS-11106, and that are approved to
Mercedes Benz MB 229.31 or MB 229.51 and
ACEA C3.Engine Oil Viscosity
CAUTION!
Your vehicle is equipped with an advanced
technology Diesel Engine and an emission
device designed to limit Diesel Particulate
Emissions from being released into the atmo-
sphere. The durability of your engine and life
expectancy of this diesel particulate filter
emission device is highly dependent on the
use of the correct engine oil.
SAE 5W-30 Synthetic Low Ash Engine Oil is
recommended for all operating temperatures.
This engine oil improves low temperature start-
ing and vehicle fuel economy.
The engine oil filler cap also shows the recom-
mended engine oil viscosity for your engine.
For information on engine oil filler cap location,
refer to “Engine Compartment” in “Maintaining
Your Vehicle” for further information.
Synthetic Engine OilsYou may use synthetic engine oils provided the
recommended oil quality requirements are met,
