2007 DODGE NITRO tire pressure

system will automatically update and the “Tire Pressure
Monitoring Telltale Light” will extinguish once the up-
dated tire pressures have been received. The vehicle may
need to be driven for up to 10 minutes above 15 mph (24
km/h) to receive this information. A low spare tire will
not cause the “Tire Pressure Monitoring Telltale Light” to
illuminate or the chime to sound.
The “Tire Pressure Monitoring Telltale Light” will flash
on and off for 60 seconds, and an audible chime will
sound when a system fault is detected. The flash cycle
will repeat every ten minutes, without an audible chime,
until the fault condition no longer exists. If the ignition
key is cycled, this sequence will repeat, providing the
system fault still exists.
NOTE:Your vehicle is either equipped with the stan-
dard compact spare tire or an optional non-matching full
size spare tire. Both of these spare tires do not have a tire
pressure monitoring sensor. Therefore, they will not bemonitored by the Tire Pressure Monitor System (TPMS).
In the event that the non-matching full size or compact
spare tire is swapped with a low pressure road tire, each
ignition key cycle will still show the “Tire Pressure
Monitoring Telltale Light” to be ON, and a chime to
sound. After the original road tire has been properly
repaired, and put back onto the vehicle in place of the
non-matching full size or compact spare tire, the TPMS
will update automatically, and the “Tire Pressure Moni-
toring Telltale Light” will be OFF as long as none of the
road tires are below the low pressure warning threshold.
The vehicle may need to be driven for up to 10 minutes
above 15 mph (24 km/h) to receive this information.
Premium System — If Equipped
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 your tires regularly and to maintain
the proper pressure.
The TPMS consists of the following components:
•Receiver Module
•4 Tire Pressure Monitoring Sensors
•3 Trigger Modules (mounted in three of the four wheel
wells)
•Various Tire Pressure Monitoring System Messages,
which display in the Electronic Vehicle Information
Center (EVIC)
•Tire Pressure Monitoring Telltale Light
Tire Pressure Monitoring Low Pressure Warnings
The “Tire Pressure Monitoring Telltale Light” will
illuminate in the instrument cluster, and an au-
dible chime will sound when one or more of the
four active road tire pressures are low. The audible chime
will sound once every ignition cycle for each condition
that it detects.
In addition, the Electronic Vehicle Information Center
(EVIC) will display a graphic of the pressure value(s)
with the low tire(s) flashing.
292 STARTING AND OPERATING

NOTE:Your system can be set to display pressure units
in PSI, kPA or BAR.
NOTE:A low spare tire will not cause the “Tire Pressure
Monitoring Telltale Light” to illuminate or the chime to
sound.
Should a low tire condition occur on any of the four
active road tire(s), you should stop as soon as possible,and inflate the low tire(s) that is flashing on the graphic
display to the vehicle’s recommended cold placard pres-
sure value. The system will automatically update, the
graphic display of the pressure value(s) will stop flash-
ing, and the “Tire Pressure Monitoring Telltale Light”
will extinguish once the updated tire pressure(s) have
been received. The vehicle may need to be driven for up
to 10 minutes above 15 mph (24 km/h) to receive this
information.
Check TPM System Message
The “Tire Pressure Monitoring Telltale Light” will
flash on and off for 60 seconds and an audible
chime will sound when a system fault is detected.
The flash cycle will repeat every ten minutes, without an
audible chime until the fault condition no longer exists.
The EVIC will display the “CHECK TPM SYSTEM”
message for 3 seconds. This text message is then followed

value(s) indicating which Tire Pressure Monitoring Sen-
sor(s) is not being received.
NOTE:Your system can be set to display pressure units
in PSI, kPA or BAR.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, theCHECK TPM SYSTEM
text message will not be present, and a pressure value
will be displayed instead of dashes.
NOTE:Your vehicle is either equipped with the stan-
dard compact spare tire or an optional non-matching full
size spare tire. Both of these spare tires do not have a tire
pressure monitoring sensor. Therefore, they will not be
monitored by the Tire Pressure Monitor System (TPMS).
In the event that the non-matching full size or compact
spare tire is swapped with a low pressure road tire, the
next ignition key cycle will still show the “Tire Pressure
Monitoring Telltale Light” to be ON, a chime to sound,
and the Electronic Vehicle Information Center (EVIC) will
still show the low tire pressure value flashing on the
graphic display.
294 STARTING AND OPERATING

However, driving the vehicle for up to 10 minutes above
15 mph (24 km/h) will display a “CHECK TPM SYS-
TEM” text message on the EVIC. This text message will
then be followed by a graphic display, with “- -“ in place
of the flashing low pressure value. For every subsequent
key cycle, the “Tire Pressure Monitoring Telltale Light”
will be ON, a chime will sound, a “CHECK TPM SYS-
TEM” text message will be displayed in the EVIC, and
the graphic display will have “- -“ in place of a pressure
value. After the original road tire has been properly
repaired, and put back onto the vehicle in place of the
non-matching full size or compact spare tire, the TPMS
will update the graphic display on the EVIC with a new
tire pressure value instead of “- -“, and the “Tire Pressure
Monitoring Telltale Light” will be OFF as long as none of
the road tires are below the low pressure warning thresh-
old. The vehicle may need to be driven for up to 10
minutes above 15 mph (24 km/h) to receive this infor-
mation.General Information

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 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.
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.
Loading
The actual total weight and the weight of the front and
rear of your vehicle at the ground can best be determined
by weighing it when it is loaded and ready for operation.
The entire vehicle should first be weighed on a commer-
cial scale to insure that the GVWR has not been exceeded.
The weight on the front and rear of the vehicle should
then be determined separately to be sure that the load is
properly distributed over front and rear axle. Weighing
the vehicle may show that the GAWR of either the front

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 the
Tires–General Information section of this manual on
Tire Pressures for proper tire inflation procedures.
Also, 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 the Tires–GeneralInformation section of this manual on Tread Wear
Indicators for the proper inspection procedure.
When replacing tires refer to the Tires–General Infor-
mation section of this manual on Replacement Tires for
proper tire replacement procedures. Replacing tires
with a higher load carrying capacity will not increase
the vehicle’s GVWR and GAWR limits.
Towing Requirements — Trailer Brakes

Donotinterconnect the hydraulic brake system or
vacuum system of your vehicle with that of the trailer.
This could cause inadequate braking and possible
personal injury.
An electronically actuated trailer brake controller is
required when towing a trailer with electronically
actuated brakes. When towing a trailer equipped with
a hydraulic surge actuated brake system, an electronic
brake controller is not required.

garden hose vertically down the face of the A/C con-
denser (if equipped) or the back of the radiator core.
Check the engine cooling system hoses for brittle rubber,
cracking, tears, cuts, and tightness of the connection at
the coolant recovery bottle and radiator. Inspect the
entire system for leaks.
With the engine at normal operating temperature (but
not running), check the cooling system pressure cap for
proper vacuum sealing by draining a small amount of
antifreeze/coolant from the radiator drain cock. If the cap
is sealing properly, the antifreeze/coolant will begin to
drain from the coolant recovery bottle. DO NOT RE-
MOVE THE COOLANT PRESSURE CAP WHEN THE
COOLING SYSTEM IS HOT.Cooling System — Drain, Flush, And Refill
At the intervals shown in the appropriate “Maintenance
Schedule,” the system should be drained, flushed, and
refilled.
If the solution is dirty and contains a considerable
amount of sediment, clean and flush with reliable cooling
system cleaner. Follow with a thorough rinsing to remove
all deposits and chemicals. Properly dispose of old
antifreeze/coolant solution.
Discard old antifreeze/coolant solution according to rec-
ommended procedure.
Selection Of Engine Coolant
Use only the manufacturer’s recommended antifreeze/
coolant, refer to Fluids, Lubricants, and Genuine Parts for
correct antifreeze/coolant type.
