2015 JEEP CHEROKEE valve

At least once a month:
•Check and adjust tire pressure with a good quality
pocket-type pressure gauge. Do not make a visual
judgement when determining proper inflation. Tires
may look properly inflated even when they are under-
inflated.
•Inspect tires for signs of tire wear or visible damage.
CAUTION!
After inspecting or adjusting the tire pressure, al-
ways reinstall the valve stem cap. This will prevent
moisture and dirt from entering the valve stem,
which could damage the valve stem.
Inflation pressures specified on the placard are always
“cold tire inflation pressure.” Cold tire inflation pressure
is defined as the tire pressure after the vehicle has not
been driven for at least three hours, or driven less than 1
mile (1.6 km) after sitting for a minimum of three hours.
The cold tire inflation pressure must not exceed the
maximum inflation pressure molded into the tire side-
wall.
Check tire pressures more often if subject to a wide range
of outdoor temperatures, as tire pressures vary with
temperature changes.
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 = 68°F (20°C) and the
outside temperature = 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.
554 STARTING AND OPERATING

CAUTION!(Continued)
•After inspecting or adjusting the tire pressure,
always reinstall the valve stem cap. This will
prevent moisture and dirt from entering the valve
stem, which could damage the Tire Pressure Moni-
toring Sensor.
NOTE:
•The TPMS is not intended to replace normal tire care
and maintenance, or to provide 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 underinflated tire causes the
tire to overheat and can lead to tire failure. Underin-
flation 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 mainte-
nance, and it is the driver ’s responsibility to maintain
correct tire pressure using an accurate tire pressure
gauge, even if underinflation has not reached the level
to trigger illumination of the “Tire Pressure Monitor-
ing Telltale Light.”
•Seasonal temperature changes will affect tire pressure,
and the TPMS will monitor the actual tire pressure in
the tire.

STARTING AND OPERATING 571

Base System
The Tire Pressure Monitor System (TPMS) uses wireless
technology with wheel rim mounted electronic sensors to
monitor tire pressure 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 check the
tire pressure in all of the tires on your vehicle monthly
and to maintain the proper pressure.
The TPMS consists of the following components:
•Receiver Module
•Four Tire Pressure Monitoring Sensors
•Tire Pressure Monitoring Telltale Light
Tire Pressure Monitoring Low Pressure Warnings
The “Tire Pressure Monitoring Telltale Light” will
illuminate in the instrument cluster, a “LOW TIRE
PRESSURE” message will display in the instrument
cluster, an#Inflate to XX#message will be displayed and
a chime will sound when tire pressure is low in one or
more of the four active road tires. 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 as shown in the#Inflate to XX#message. Once the
system receives the updated tire pressures, the system
will automatically update and the “Tire Pressure Moni-
toring Telltale Light” will turn off.
572 STARTING AND OPERATING

2. If you install the compact or non-matching full size
spare tire in place of a road tire that has a pressure
below the low-pressure warning limit, a chime will
sound and the “TPMS Telltale Light” and “LOW TIRE
PRESSURE” and#Inflate to XX#messages will turn on
upon the next ignition cycle.
3. After driving the vehicle for up to 20 minutes above
15 mph (24 km/h), the “TPMS Telltale Light” will
flash on and off for 75 seconds and then remain on
solid.
4. For each subsequent ignition cycle, a chime will sound
and the “TPMS Telltale Light” will flash on and off for
75 seconds and then remain on solid.
5. Once you repair or replace the original road tire and
reinstall it on the vehicle in place of the compact spare
or non-matching full size spare, the TPMS will update
automatically and the “TPMS Telltale Light” will turn
off, as long as no tire pressure is below the low-
pressure warning limit in any of the four active road
tires. The vehicle may need to be driven for up to 20
minutes above 15 mph (24 km/h) in order for the
TPMS to receive this information.

from the vehicle or tire and wheel components. Once
the sealant dries, it can easily be peeled off and
properly discarded.
•For optimum performance, make sure the valve stem
on the wheel is free of debris before connecting the Tire
Service Kit.
•You can use the Tire Service Kit air pump to inflate
bicycle tires. The kit also comes with two needles,
located in the Accessory Storage Compartment (on the
bottom of the air pump) for inflating sport balls, rafts,
or similar inflatable items. However, use only the Air
Pump Hose (7) and make sure the Mode Select Knob
(5) is in the Air Mode when inflating such items to
avoid injecting sealant into them. The Tire Service Kit
Sealant is only intended to seal punctures less than¼”
(6 mm) diameter in the tread of your vehicle.
•Do not lift or carry the Tire Service Kit by the hoses.
WARNING!
•Do not attempt to seal a tire on the side of the
vehicle closest to traffic. Pull far enough off the
road to avoid the danger of being hit when using
the Tire Service Kit.
•Do not use Tire Service Kit or drive the vehicle
under the following circumstances:
– If the puncture in the tire tread is approximately
1/4” (6 mm) or larger.
– If the tire has any sidewall damage.
– If the tire has any damage from driving with
extremely low tire pressure.
– If the tire has any damage from driving on a flat
tire.
– If the wheel has any damage.
– If you are unsure of the condition of the tire or
the wheel.

Sealing A Tire With Tire Service Kit
(A) Whenever You Stop To Use Tire Service Kit:
1. Pull over to a safe location and turn on the vehicle’s
Hazard Warning flashers.
2. Verify that the valve stem (on the wheel with the
deflated tire) is in a position that is near to the ground.
This will allow the Tire Service Kit Hoses (6) and (7) to
reach the valve stem and keep the Tire Service Kit flat
622 WHAT TO DO IN EMERGENCIES

on the ground. This will provide the best positioning
of the kit when injecting the sealant into the deflated
tire and running the air pump. Move the vehicle as
necessary to place the valve stem in this position
before proceeding.
3. Place the transmission in PARK (auto transmission) or
in Gear (manual transmission) and turn Off the igni-
tion.
4. Set the parking brake.
(B) Setting Up To Use Tire Service Kit:
1. Push in the Mode Select Knob (5) and turn to the
Sealant Mode position.
2. Uncoil the Sealant Hose (6) and then remove the cap
from the fitting at the end of the hose.
3. Place the Tire Service Kit flat on the ground next to the
deflated tire.
4. Remove the cap from the valve stem and then screw
the fitting at the end of the Sealant Hose (6) onto the
valve stem.
5. Uncoil the Power Plug (8) and insert the plug into the
vehicle’s 12 Volt power outlet.
NOTE:Do not remove foreign objects (e.g., screws or
nails) from the tire.
(C) Injecting Tire Service Kit Sealant Into The
Deflated Tire:
•Always start the engine before turning ON the Tire
Service Kit.
NOTE:Manual transmission vehicles must have the
parking brake engaged and the shift lever in NEUTRAL.
•After pressing the Power Button (4), the sealant (white
fluid) will flow from the Sealant Bottle (1) through the
Sealant Hose (6) and into the tire.
6
WHAT TO DO IN EMERGENCIES 623

NOTE:Sealant may leak out through the puncture in the
tire.
If the sealant (white fluid) does not flow within0–10
seconds through the Sealant Hose (6):
1. Press the Power Button (4) to turn Off the Tire Service
Kit. Disconnect the Sealant Hose (6) from the valve
stem. Make sure the valve stem is free of debris.
Reconnect the Sealant Hose (6) to the valve stem.
Check that the Mode Select Knob (5) is in the Sealant
Mode position and not Air Mode. Press the Power
Button (4) to turn On the Tire Service Kit.
2. Connect the Power Plug (8) to a different 12 Volt
power outlet in your vehicle or another vehicle, if
available. Make sure the engine is running before
turning ON the Tire Service Kit.
3. The Sealant Bottle (1) may be empty due to previous
use. Call for assistance.
NOTE:If the Mode Select Knob (5) is on Air Mode and
the pump is operating, air will dispense from the Air
Pump Hose (7) only, not the Sealant Hose (6).
If the sealant (white fluid) does flow through the
Sealant Hose (6):
1. Continue to operate the pump until sealant is no
longer flowing through hose (typically takes 30 - 70
seconds). As the sealant flows through the Sealant
Hose (6), the Pressure Gauge (3) can read as high as 70
psi (4.8 Bar). The Pressure Gauge (3) will decrease
quickly from approximately 70 psi (4.8 Bar) to the
actual tire pressure when the Sealant Bottle (1) is
empty.
2. The pump will start to inject air into the tire immedi-
ately after the Sealant Bottle (1) is empty. Continue to
operate the pump and inflate the tire to the pressure
indicated on the tire pressure label on the driver-side
