2014 JEEP CHEROKEE inflation pressure

- Air Bag Warning Light
This 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
authorized dealer as soon as possible. Refer to “Occupant Restraints” in “Things To
Know Before Starting Your Vehicle” of your Owner’s Manual for further information.
NOTE:
The Air Bag System is designed to be maintenance free.
- Electronic Throttle Control (ETC) Light
This light informs you of a problem with the Electronic Throttle Control (ETC) system.
If a problem is detected, the light will come on while the engine is running. Cycle the
ignition key when the vehicle has completely stopped and the shift lever/gear selector
is placed in the PARK position; the light should turn off.
If the light remains lit with the engine running, your vehicle will usually be drivable;
however, see an authorized service center immediately. If the light is flashing when
the engine is running, immediate service is required and you may experience reduced
performance, an elevated/rough idle or engine stall and your vehicle may require
towing.
- Tire Pressure Monitoring System (TPMS) Light
Each tire, including the spare (if provided), should be checked monthly, when cold
and inflated to the inflation pressure recommended by the vehicle manufacturer 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) which display in the Electronic Vehicle Information
Center (EVIC) when one or more of your tires is significantly under-inflated.
Accordingly, when the low tire pressure EVIC display illuminates, you should stop and
check your tires as soon as possible, and inflate them to the proper 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.
IF THE LIGHT STARTS FLASHING INDICATING A LOW TIRE PRESSURE, ADJUST THE AIR
PRESSURE IN THE LOW TIRE TO THE AIR PRESSURE SHOWN ON THE VEHICLE PLACARD OR
TIRE INFLATION PRESSURE LABEL LOCATED ON THE DRIVER'S DOOR.

NOTE:
After inflation, the vehicle may need to be driven for 20 minutes before the flashing light
will turn off.
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 EVIC display.
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 approximately one minute and then remain continuously
illuminated. This sequence will continue each time the vehicle is restarted 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.
NOTE:
Tire pressures change by approximately 1 psi (7 kPa) per 12° F (7° C) of air
temperature change. Keep this in mind when checking tire pressure inside a garage,
especially in the Winter. Example: If garage temperature is 68°F (20°C) and the
outside temperature is 32°F (0°C), then the cold tire inflation pressure should be
increased by 3 psi (21 kPa), which equals 1 psi (7 kPa) for every 12°F (7°C) for this
outside temperature condition.
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 result when using
replacement equipment that is not of the same size, type, and/or style. Aftermar-
ket wheels can cause sensor damage. 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.

If the tire does not inflate to at least 26 psi (1.8 Bar) pressure within 15 minutes:
The tire is too badly damaged. Do not attempt to drive the vehicle further. Call for
assistance.
NOTE:
If the tire becomes over-inflated, press the Deflation Button to reduce the tire
pressure to the recommended inflation pressure before continuing.
If the tire inflates to the recommended pressure or is at least 26 psi (1.8 Bar) pressure
within 15 minutes:
1. Press the Power Button (4) to turn off the TIREFIT kit.
2. Remove the Speed Limit sticker from the top of the Sealant Bottle (1) and placethe sticker on the instrument panel.
3. Immediately disconnect the Sealant Hose (6) from the valve stem, reinstall the cap on the fitting at the end of the hose, and place the TIREFIT kit in the vehicle
storage location. Quickly proceed to (D) “Drive Vehicle.”
(D) Drive Vehicle:
Immediately after injecting sealant and inflating the tire, drive the vehicle 5 miles
(8 km) or 10 minutes to ensure distribution of the TIREFIT Sealant within the tire. Do
not exceed 55 mph (88 km/h).
(E) After Driving:
Pull over to a safe location. Refer to “Whenever You Stop to Use TIREFIT” before
continuing.
1. Turn the Mode Select Knob (5) to the Air Mode position.
2. Uncoil the Air Pump Hose (7) (black in color) and screw the fitting at the end ofhose (7) onto the valve stem.
3. Uncoil the power plug and insert the plug into the vehicles 12 Volt power outlet.
4. Check the pressure in the tire by reading the Pressure Gauge (3).
If tire pressure is less than 19 psi (1.3 Bar), the tire is too badly damaged. Do not attempt
to drive the vehicle further. Call for assistance.

TIRE PRESSURES
Check the inflation pressure of each tire, including the spare tire, at least monthly
and inflate to the recommended pressure for your vehicle.
The tire pressures recommended for your vehicle are found on the “Tire and Loading
Information” label located on the driver’s side door opening.
NOTE:
Refer to the Owner's Manual on the DVD
for more information regarding tire warn-
ings and instructions.
WARNING!
• Overloading of your tires is dangerous. Overloading can cause tire failure,affect vehicle handling, and increase your stopping distance. Use tires of the
recommended load capacity for your vehicle. Never overload them.
• Improperly inflated tires are dangerous and can cause collisions. Under-
inflation is the leading cause of tire failure and may result in severe cracking,
component separation, or “blow out”. Over-inflation reduces a tire’s ability to
cushion shock. Objects on the road and chuck holes can cause damage that
results in tire failure. Unequal tire pressures can cause steering problems. You
could lose control of your vehicle. Over-inflated or under-inflated tires can
affect vehicle handling and can fail suddenly, resulting in loss of vehicle
control.
