2017 JEEP CHEROKEE tires

may need to be driven for up to 10 minutes above 15.5 mph
(25 km/h) in order for the TPMS to receive this informa-
tion.
For example, your vehicle may have a recommended cold
(parked for more than three hours) placard 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 tempera-
ture drop to 20°F (-7°C) will decrease the tire pressure to
approximately 24 psi (165 kPa). This tire pressure is low
enough to turn ON the “Tire Pressure Monitoring Telltale
Light.” Driving the vehicle may cause the tire pressure to
rise to approximately 28 psi (193 kPa), but the “Tire
Pressure Monitoring Telltale Light” will still be on. In this
situation, the “Tire Pressure Monitoring Telltale Light” will
turn off only after the tires are inflated to the vehicle’s
recommended cold placard pressure value.
NOTE:When filling warm tires, the tire pressure may need
to be increased up to an additional 4 psi (30 kPa) above the
recommended cold placard pressure in order to turn the
Tire Pressure Monitoring Telltale Light off.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 op-
eration or sensor damage may result when using
replacement equipment that is not of the same size,
type, and/or style. Aftermarket wheels can cause
sensor damage.
• Using aftermarket tire sealants may cause the Tire
Pressure Monitoring System (TPMS) sensor to be-
come inoperable. After using an aftermarket tire
sealant it is recommended that you take your vehicle
to an authorized dealer to have your sensor function
checked.
• After inspecting or adjusting the tire pressure always
reinstall the valve stem cap. This will prevent mois-
ture and dirt from entering the valve stem, which
could damage the TPMS sensor.
NOTE:
• The TPMS is not intended to replace normal tire care and
maintenance, or to provide warning of a tire failure or
condition.
196 SAFETY

•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. Underinfla-
tion 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 Monitoring
Telltale Light”.
• Seasonal temperature changes will affect tire pressure,
and the TPMS will monitor the actual tire pressure in the
tire.
Premium 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.
• Various tire pressure monitoring system messages,
which display in the instrument cluster.
• Tire pressure monitoring telltale light.
Tire Pressure Monitoring Low Pressure Warnings
The “Tire Pressure Monitoring Telltale Light” will
illuminate in the instrument cluster and a chime
will sound when tire pressure is low in one or more of the
four active road tires. In addition, the instrument cluster
will display a Tire Lowmessage for a minimum of five
seconds, an Inflate to XX message and a graphic showing
the pressure values of each tire with the low tire pressure
values in a different color.

SAFETY 197

Should this occur, you should stop as soon as possible and
inflate the tires with low pressure (those in a different color
in the instrument cluster graphic) to the vehicle’s recom-
mended cold placard pressure value as shown in the
Inflate to XXmessage. Once the system receives the
updated tire pressures, the system will automatically up-
date, the pressure values in the graphic display in the
instrument cluster will return to their original color, and
the “Tire Pressure Monitoring Telltale Light” will turn off. NOTE:
When filling warm tires, the tire pressure may need
to be increased up to an additional 4 psi (30 kPa) above the
recommended cold placard pressure in order to turn the
Tire Pressure Monitoring Telltale Light off.
The vehicle may need to be driven for up to 20 minutes
above 15.5 mph (25 km/h) in order for the TPMS to receive
this information.
SERVICE TPMS Warning
When a system fault is detected, the “Tire Pressure Moni-
toring Telltale Light” will flash on and off for 75 seconds
and then remain on solid. The system fault will also sound
a chime. In addition, the instrument cluster will display a
SERVICE TPM SYSTEM message for a minimum of five
seconds and then display dashes (- -) in place of the
pressure value to indicate which sensor is not being
received.
Tire Pressure Monitoring Low Pressure Warning
198 SAFETY

If the ignition key is cycled, this sequence will repeat,
providing the system fault still exists. If the system fault no
longer exists, the “Tire Pressure Monitoring Telltale Light”
will no longer flash, and the “SERVICE TPM SYSTEM”
message will no longer display, and a pressure value will
display in place of the dashes. A system fault can occur due
to any of the following:
1. Jamming due to electronic devices or driving next tofacilities emitting the same radio frequencies as the
TPMS sensors. 2. Installing some form of aftermarket window tinting that
affects radio wave signals.
3.
Lots of snow or ice around the wheels or wheel housings.
4. Using tire chains on the vehicle.
5. Using wheels/tires not equipped with TPMS sensors.
Vehicles With Compact Spare or Non-Matching Full Size
Spare
1. The compact spare tire or non-matching full size does not have a tire pressure monitoring sensor. Therefore,
the TPMS will not monitor the pressure in the compact
spare tire.
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, upon the next ignition
key cycle, the “TPMS Telltale Light” will remain on and
a chime will sound. In addition, the graphic in the
instrument cluster will still display a different color
pressure value and an Inflate to XXmessage.

3.After driving the vehicle for up to 20 minutes above
15.5 mph (25 km/h), the “TPMS Telltale Light” will flash
on and off for 75 seconds and then remain on solid. In
addition, the instrument cluster will display a “SERVICE
TPM SYSTEM” message for five seconds and then display
dashes (- -) in place of the pressure value.
4. For each subsequent ignition key cycle, a chime willsound, the “TPMS Telltale Light” will flash on and off
for 75 seconds and then remain on solid, and the
instrument cluster will display a “SERVICE TPM SYS-
TEM” message for five seconds and then display dashes
(- -) in place of the pressure value.
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, the TPMS will update automati-
cally. In addition, the “TPMS Telltale Light” will turn off
and the graphic in the instrument cluster will display a
new pressure value instead of dashes (- -), 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 15.5 mph (25 km/h)
in order for the TPMS to receive this information.
TPMS Deactivation — If Equipped
The TPMS can be deactivated if replacing all four wheel
and tire assemblies (road tires) with wheel and tire assem-
blies that do not have TPMS Sensors, such as when
installing winter wheel and tire assemblies on your vehicle.
To deactivate the TPMS, first, replace all four wheel and
tire assemblies (road tires) with tires not equipped with
Tire Pressure Monitoring (TPM) Sensors. Then, drive the
vehicle for 10 minutes above 15.5 mph (25 km/h). The
TPMS will chime, the TPM Telltale Lightwill flash on and
off for 75 seconds and then remain on. The instrument
cluster will display the “SERVICE TPM SYSTEM” message
and then display dashes (--) in place of the pressure values.
Beginning with the next ignition cycle, the TPMS will no
longer chime or display the “SERVICE TPM SYSTEM”
message in the instrument cluster but dashes (--) will
remain in place of the pressure values.
To reactivate the TPMS, replace all four wheel and tire
assemblies (road tires) with tires equipped with TPM
sensors. Then, drive the vehicle for up to 10 minutes above
15.5 mph (25 km/h). The TPMS will chime, the TPM
Telltale Light will flash on and off for 75 seconds and then
turn off. The instrument cluster will display the “SERVICE
TPM SYSTEM” message and then display pressure values

WARNING!(Continued)
•NEVER place any objects under the floor mat (e.g.,
towels, keys, etc.). These objects could change the
position of the floor mat and may cause interference
with the accelerator, brake, or clutch pedals.
• If the vehicle carpet has been removed and re-
installed, always properly attach carpet to the floor
and check the floor mat fasteners are secure to the
vehicle carpet. Fully depress each pedal to check for
interference with the accelerator, brake, or clutch
pedals then re-install the floor mats.
• It is recommended to only use mild soap and water
to clean your floor mats. After cleaning, always check
your floor mat has been properly installed and is
secured to your vehicle using the floor mat fasteners
by lightly pulling mat.
Periodic Safety Checks You Should Make Outside
The Vehicle
Tires
Examine tires for excessive tread wear and uneven wear
patterns. Check for stones, nails, glass, or other objects
lodged in the tread or sidewall. Inspect the tread for cuts
and cracks. Inspect sidewalls for cuts, cracks, and bulges.
Check the wheel nuts for tightness. Check the tires (includ-
ing spare) for proper cold inflation pressure.
Lights
Have someone observe the operation of brake lights and
exterior lights while you work the controls. Check turn signal
and high beam indicator lights on the instrument panel.
Door Latches
Check for proper closing, latching, and locking.
Fluid Leaks
Check area under vehicle after overnight parking for fuel,
engine coolant, oil, or other fluid leaks. Also, if gasoline
fumes are detected or if fuel, power steering fluid (if
equipped), or brake fluid leaks are suspected. The cause
should be located and corrected immediately.

FOUR-WHEEL DRIVE OPERATION
1-Speed Four-Wheel Drive (4X4) — If Equipped
This feature provides on-demand four-wheel drive (4X4).
The system is automatic with no driver inputs or addi-
tional driving skills required. Under normal driving con-
ditions, the front wheels provide most of the traction. If the
front wheels begin to lose traction, power is shifted auto-
matically to the rear wheels. The greater the front wheel
traction loss, the greater the power transfer to the rear
wheels.Additionally, on dry pavement under heavy throttle input
(where one may have no wheel spin), torque will be sent to
the rear in a pre-emptive effort to improve vehicle launch
and performance characteristics.
CAUTION!
All wheels must have the same size and type tires.
Unequal tire sizes must not be used. Unequal tire size
may cause failure of the power transfer unit.

1-Speed 4X4 Switch2-Speed 4x4 Switch
278 STARTING AND OPERATING

The Four-Wheel Drive is fully automatic in the normal
driving mode. The Selec-Terrain buttons provide three
selectable mode positions:
•4WD LOW
• REAR LOCK (If Equipped)
• NEUTRAL When additional traction is required, the 4WD LOW range
position can be used to provide an additional gear reduc-
tion which allows for increased torque to be delivered to
both the front and rear wheels. 4WD LOW is intended for
loose, slippery road surfaces only. Driving in 4WD LOW on
dry, hard-surfaced roads may cause increased tire wear and
damage to driveline components.
When operating your vehicle in 4WD LOW, the engine
speed is approximately three times that of the normal
driving mode at a given road speed. Take care not to
overspeed the engine and do not exceed 25 mph (40 km/h).
Proper operation of four-wheel drive vehicles depends on
tires of equal size, type, and circumference on each wheel.
Any difference will adversely affect shifting and cause
damage to the driveline components.
Because four-wheel drive provides improved traction,
there is a tendency to exceed safe turning and stopping
speeds. Do not go faster than road conditions permit.
