2013 JEEP GRAND CHEROKEE fuel pressure

The “ESC Activation/Malfunction Indicator Light”
(located in the instrument cluster) starts to flash
as soon as the tires lose traction and the ESC
system becomes active. The “ESC Activation/
Malfunction Indicator Light” also flashes when
TCS is active. If the “ESC Activation/Malfunction
Indicator Light” begins to flash during accelera-
tion, ease up on the accelerator and apply as little
throttle as possible. Be sure to adapt your speed
and driving to the prevailing road conditions.
NOTE:
•The “ESC Activation/Malfunction Indica-
tor Light” and the “ESC OFF Indicator
Light” come on momentarily each time
the ignition switch is turned ON.
• Each time the ignition is turned ON, the
ESC system will be ON even if it was
turned off previously.
• The ESC system will make buzzing or
clicking sounds when it is active. This is
normal; the sounds will stop when ESC
becomes inactive following the maneuver
that caused the ESC activation.
The “ESC OFF Indicator Light” indi-
cates the Electronic Stability Control
(ESC) is off.
TIRES — GENERAL
INFORMATION
Tire PressureProper tire inflation pressure is essential to the
safe and satisfactory operation of your vehicle.
Three primary areas are affected by improper
tire pressure:
Safety
WARNING!
•Improperly inflated tires are dangerous
and can cause collisions.
• Under-inflation increases tire flexing and
can result in over-heating and tire failure.
(Continued)
WARNING!(Continued)
•Over-inflation reduces a tire’s ability to
cushion shock. Objects on the road and
chuckholes can cause damage that result
in tire failure.
• Over-inflated or under-inflated tires can
affect vehicle handling and can fail sud-
denly, resulting in loss of vehicle control.
• Unequal tire pressures can cause steering
problems. You could lose control of your
vehicle.
• Unequal tire pressures from one side of
the vehicle to the other can cause the
vehicle to drift to the right or left.
• Always drive with each tire inflated to the
recommended cold tire inflation pressure.
Economy
Improper inflation pressures can cause uneven
wear patterns to develop across the tire tread.
These abnormal wear patterns will reduce tread
life resulting in a need for earlier tire replace-
ment. Under-inflation also increases tire rolling
resistance resulting in higher fuel consumption.
259

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
the level to trigger illumination of the Tire
Pressure Monitoring Telltale Light.
• Seasonal temperature changes will affect
tire pressure, and the TPMS will monitor
the actual tire pressure in the tire.Base SystemThe Tire Pressure Monitor System (TPMS)
uses wireless technology with wheel rim-
mounted electronic sensors to monitor tire pres-
sure levels. Sensors, mounted to each wheel as
part of the valve stem, transmit tire pressure
readings to the Receiver Module.
NOTE:
It is particularly important, for you to regu-
larly check the tire pressure in all of your
tires, and to maintain the proper pressure.
The TPMS consists of the following compo-
nents:
•Receiver Module
• Four Tire Pressure Monitoring Sensors
• Tire Pressure Monitoring Telltale Light
A low spare tire will not cause the Tire Pressure
Monitoring Telltale Light to illuminate, a warning
message to appear, or the chime to sound. The Tire Pressure Monitoring Telltale
Light will illuminate in the instrument
cluster, a “LOW TIRE PRESSURE”
message will display in the instrument
cluster for 5 seconds, an "Inflate to XXX"mes-
sage will be displayed and an audible chime will
be activated, when one or more of the four
active road tire pressures are low. Should this
occur, you should stop as soon as possible,
check the inflation pressure of each tire on your
vehicle, and inflate each tire to the vehicle’s
recommended cold placard pressure value dis-
played in the "Inflate to XXX" message. The
system will automatically update and the Tire
Pressure Monitoring Telltale Light will extin-
guish, 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.

At Each Stop for Fuel
•Check the engine oil level about 5 minutes
after a fully warmed engine is shut off.
Checking the oil level while the vehicle is on
level ground will improve the accuracy of the
oil level reading. Add oil only when the level
is at or below the ADD or MIN mark.
• Check the windshield washer solvent and
add if required.
Once a Month
• Check tire pressure and look for unusual
wear or damage.
• Inspect the battery and clean and tighten the
terminals as required. •
Check the fluid levels of the coolant reservoir,
brake master cylinder, power steering and
transmission (5.7L only) and add as needed.
• Check all lights and other electrical items for
correct operation.
At Each Oil Change
• Change the engine oil filter.
• Inspect the brake hoses and lines.
CAUTION!
Failure to perform the required maintenance
items may result in damage to the vehicle. 7,500 Miles (12,000 km) or 12 Months

Maintenance Schedule – Diesel
Engine
To help you have the best driving experience
possible, the manufacturer has identified the
specific vehicle maintenance service intervals
that are required to keep your vehicle operating
properly and safely.
The manufacturer recommends that these main-
tenance intervals be performed at your selling
dealer. The technicians at your dealership know
your vehicle best, and have access to factory
trained information, genuine MOPAR® parts, and
specially designed electronic and mechanical
tools that can help prevent future costly repairs.
The maintenance intervals shown should be
performed as indicated in this section. NOTE:
•
Under no circumstances should oil change
intervals exceed 12,500 miles (20 000 km) or
12 months, whichever comes first.
•
Flush and replace the engine coolant at
120 months or 150,000 miles (240,000 km)
whichever comes first.
At Each Stop for Fuel
• Check the engine oil level about 15 minutes
after a fully warmed engine is shut off.
Checking the oil level while the vehicle is on
level ground will improve the accuracy of the
oil level reading. Add oil only when the level
is at or below the ADD or MIN mark.
• Check the windshield washer solvent and
add if required.
Once a Month
• Check tire pressure and look for unusual
wear or damage.
• Inspect the battery and clean and tighten the
terminals as required. •
Check the fluid levels of the coolant reservoir,
brake master cylinder, and power steering
and add as needed.
• Check all lights and other electrical items for
correct operation.
At Each Oil Change
• Change the engine oil filter.
• Inspect the brake hoses and lines.
• Inspect for the presence of water in the fuel
filter/water separator unit.
CAUTION!
Failure to perform the required maintenance
items may result in damage to the vehicle.
