2015 JEEP COMPASS inflation pressure

TIRE PRESSURE MONITORING SYSTEM (TPMS)
The Tire Pressure Monitor System (TPMS) will warn the
driver of a low tire pressure based on the vehicle recom-
mended cold placard pressure.
The tire pressure will vary with temperature by about 1 psi
(7.0 kPa) for every 12°F (6.5°C). This means that when the
outside temperature decreases, the tire pressure will de-
crease. Tire pressure should always be set based on “cold
inflation tire pressure”. This 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 a three hour
period. The cold tire inflation pressure must not exceed the
maximum inflation pressure molded into the tire sidewall.
Refer to “Tires – General Information” in “Starting and
Operating” for information on how to properly inflate the
vehicle’s tires. The tire pressure will also increase as the
vehicle is driven - this is normal and there should be no
adjustment for this increased pressure.
The TPMS will warn the driver of a low tire pressure if
the tire pressure falls below the low-pressure warning
limit for any reason, including low temperature effects, or
natural pressure loss through the tire.
The TPMS will continue to warn the driver of low tire
pressure as long as the condition exists, and will not turn
off until the tire pressure is at or above the recommended
cold placard pressure. Once the low tire pressure warn-
ing (Tire Pressure Monitoring Telltale Light) illuminates,
you must increase the tire pressure to the recommended
cold placard pressure in order for the Tire Pressure
Monitoring Telltale Light to turn off. The system will
automatically update and the Tire Pressure Monitoring
Telltale Light will turn off once the system receives the
updated tire pressures. 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.

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 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 mainte-
nance, 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.

STARTING AND OPERATING 395

Base System
This is the TPMS warning indicator located in the
instrument cluster.
The 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 regularly
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 illumi-
nate in the instrument cluster, a LOW TIRE message will
be displayed for a minimum of five seconds, 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. The system will automatically update and the Tire
Pressure Monitoring Light will extinguish and the LOW
TIRE message will turn off once the updated tire pres-
sures 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.
396 STARTING AND OPERATING

Inflation Pressure
This is the cold tire inflation pressure for your vehicle for
all loading conditions up to full GAWR.
Curb Weight
The curb weight of a vehicle is defined as the total weight
of the vehicle with all fluids, including vehicle fuel, at
full capacity conditions, and with no occupants or cargo
loaded into the vehicle. The front and rear curb weight
values are determined by weighing your vehicle on a
commercial scale before any occupants or cargo are
added.
Overloading
The load carrying components (springs, tires, wheels,
etc.) of your vehicle will provide satisfactory service as
long as you do not exceed the GVWR.
The best way to figure out the total weight of your
vehicle is to weigh it when it is fully loaded and ready for
operation. Weigh it on a commercial scale to ensure that
it is not over the GVWR.
Overloading can cause potential safety hazards and
shorten useful service life. Heavier suspension compo-
nents do not necessarily increase the vehicle’s GVWR.
Loading
To load your vehicle properly, first figure out its empty
weight. Store heavier items down low and be sure you
distribute their weight as evenly as possible. Stow all
loose items securely before driving. Improper weight
distribution can have an adverse effect on the way
your vehicle steers and handles, and the way the brakes
operate.

STARTING AND OPERATING 411

WARNING!(Continued)
•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 uti-
lized.
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 – General Information” in “Starting And Oper-
ating” for proper tire inflation procedures.
•Check the trailer tires for proper tire inflation pres-
sures before trailer usage.
•Check for signs of tire wear or visible tire damage
before towing a trailer. Refer to “Tires – General
Information” in “Starting And Operating” for the
proper inspection procedure.
•When replacing tires, refer to “Tires – General Infor-
mation” in “Starting And Operating” for the proper
tire replacement procedures. Replacing tires with a
higher load carrying capacity will not increase the
vehicle’s GVWR and GAWR limits.
420 STARTING AND OPERATING

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 Defla-
tion Button to reduce the tire pressure to the recom-
mended inflation pressure before continuing.
