2017 JEEP CHEROKEE tire pressure

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
200 SAFETY

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.

SAFETY 255

VEHICLE LOADING
Certification Label
As required by National Highway Traffic Safety Adminis-
tration regulations, your vehicle has a certification label
affixed to the driver’s side door or pillar.
This label contains the month and year of manufacture,
Gross Vehicle Weight Rating (GVWR), Gross Axle Weight
Rating (GAWR) front and rear, and Vehicle Identification
Number (VIN). A Month-Day-Hour (MDH) number is
included on this label and indicates the Month, Day and
Hour of manufacture. The bar code that appears on the
bottom of the label is your VIN.
Gross Vehicle Weight Rating (GVWR)
The GVWR is the total permissible weight of your vehicle
including driver, passengers, vehicle, options and cargo.
The label also specifies maximum capacities of front and
rear axle systems (GAWR). Total load must be limited so
GVWR and front and rear GAWR are not exceeded.
Payload
The payload of a vehicle is defined as the allowable load
weight a truck can carry, including the weight of the driver,
all passengers, options and cargo.
Gross Axle Weight Rating (GAWR)
The GAWR is the maximum permissible load on the front
and rear axles. The load must be distributed in the cargo
area so that the GAWR of each axle is not exceeded.
Each axle GAWR is determined by the components in the
system with the lowest load carrying capacity (axle,
springs, tires or wheels). Heavier axles or suspension
components sometimes specified by purchasers for in-
creased durability does not necessarily increase the vehi-
cle’s GVWR.
Tire Size
The tire size on the Vehicle Certification Label represents
the actual tire size on your vehicle. Replacement tires must
be equal to the load capacity of this tire size.
Rim Size
This is the rim size that is appropriate for the tire size
listed.
Inflation Pressure
This is the cold tire inflation pressure for your vehicle for
all loading conditions up to full GAWR.

WARNING!(Continued)
•When hauling cargo, or towing a trailer, do not over-
load your vehicle or trailer. Overloading can cause a
loss of control, poor performance, or damage to brakes,
axle, engine, transmission, steering, suspension, chas-
sis structure, or tires.
•Safety chains must always be used between your
vehicle and trailer. Always connect the chains to the
frame or hook retainers of the vehicle hitch. Cross the
chains under the trailer tongue and allow enough slack
for turning corners.
•Vehicles with trailers should not be parked on a grade.
When parking, apply the parking brake on the tow
vehicle. Put the tow vehicle transmission in PARK.
Always, block or chockthe trailer wheels.
•GCWR must not be exceeded.
•
Total weight must be distributed between the tow
vehicle and the trailer such that the following four
ratings are not exceeded:
1. GVWR
2. GTW
3. GAWR
4. Tongue weight rating for the trailer hitch utilized.
CAUTION!
• Do not tow a trailer at all during the first 500 miles
(805 km) the new vehicle is driven. The engine, axle
or other parts could be damaged.
• Then, during the first 500 miles (805 km) that a trailer
is towed, do not drive over 50 mph (80 km/h) and do
not make starts at full throttle. This helps the engine
and other parts of the vehicle wear in at the heavier
loads.
Towing Requirements — Tires
• Do not attempt to tow a trailer while using a compact
spare tire.
• Proper tire inflation pressures are essential to the safe
and satisfactory operation of your vehicle. Refer to
“Tires” in “Servicing And Maintenance” for proper tire
inflation procedures.
• Check the trailer tires for proper tire inflation pressures
before trailer usage.
• Check for signs of tire wear or visible tire damage before
towing a trailer. Refer to “Tires” in “Servicing And
Maintenance” for the proper inspection procedure.
