2020 DODGE GRAND CARAVAN tire pressure

116SAFETY
(Continued)
NOTE:
When filling warm tires, the tire pressure may
need to be increased up to an additional 4 psi
(28 kPa) above the recommended cold placard
pressure in order to turn the TPMS Warning
Light off. 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 pres-
sure gauge while adjusting your tire pressure.
Driving on a significantly underinflated tire
causes the tire to overheat and can lead to
tire failure. Underinflation 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
maintenance, and it is the driver’s responsi -
bility to maintain correct tire pressure using
an accurate tire pressure gauge, even if
underinflation has not reached the level to
trigger illumination of the TPMS Warning
Light.
Seasonal temperature changes will affect
tire pressure, and the TPMS will monitor the
actual tire pressure in the tire.
System Operation
The Tire Pressure Monitoring 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.
CAUTION!
The TPMS has been optimized for the orig -
inal equipment tires and wheels. TPMS
pressures and warning have been estab -
lished for the tire size equipped on your
vehicle. Undesirable system operation or
sensor damage may result when using
replacement equipment that is not of the
same size, type, and/or style. The TPM
sensor is not designed for use on after -
market wheels and may contribute to a
poor overall system performance or sensor
damage. Customers are encouraged to use
OEM wheels to assure proper TPM feature
operation.
Using aftermarket tire sealants may cause
the Tire Pressure Monitoring System
(TPMS) sensor to become inoperable. After
using an aftermarket tire sealant it is
recommended that you take your vehicle to
your authorized dealer to have your sensor
function checked.
After inspecting or adjusting the tire pres -
sure always reinstall the valve stem cap.
This will prevent moisture and dirt from
entering the valve stem, which could
damage the TPMS sensor.
CAUTION! (Continued)

SAFETY117
The Tire Pressure Monitoring System (TPMS)
consists of the following components:
Receiver Module
Four Tire Pressure Monitoring sensors
Tire Pressure Monitoring System Warning
Light
Tire Pressure Monitoring Low Tire Pressure
Warnings The TPMS Warning Light will
illuminate in the instrument cluster, a
“LOW TIRE PRESSURE” message will
display in the instrument cluster, 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 tire placard
pressure value (located on the placard label on
the driver's-side B-Pillar).
NOTE:
When filling warm tires, the tire pressure may
need to be increased up to an additional 4 psi
(28 kPa) above the recommended cold placard
pressure in order to turn the TPMS Warning
Light off. The system will automatically update and the
TPMS Warning Light will extinguish once the
updated tire pressures have been received.
NOTE:
The vehicle may need to be driven for up to
20 minutes above 15 mph (24 km/h) to receive
this information.
Service TPMS
The TPMS Warning Light will flash on and off for
75 seconds, and remain on solid when a system
fault is detected. The system fault will also
sound a chime. If the ignition switch is cycled,
this sequence will repeat, providing the system
fault still exists. The TPMS Warning Light will
turn off when the fault condition no longer
exists. A system fault can occur with any of the
following scenarios:
Jamming due to electronic devices or driving
next to facilities emitting the same radio
frequencies as the TPMS sensors.
Installing some form of aftermarket window
tinting that affects radio wave signals.
Accumulation of excessive snow and/or ice
around the wheels or wheel housings.
Using tire chains on the vehicle.
Using wheels/tires not equipped with TPMS
sensors.
Vehicles With Compact Spare
The compact spare tire (if equipped) does not
have a TPMS sensor. Therefore the TPMS will
not monitor the pressure in the compact
spare tire.
If you install the compact spare tire in place
of a road tire that has a pressure below the
low-pressure warning limit, upon the next
ignition switch cycle, a chime will sound, a
“LOW TIRE PRESSURE” message will be
displayed and the TPMS Warning Light will
turn on.
After driving for up to 20 minutes above
15 mph (24 km/h), the TPMS Warning Light
will flash on and off for 75 seconds and then
remain on solid.
For each subsequent ignition switch cycle, a
chime will sound, the TPMS Warning Light will
flash on and off for 75 seconds and then
remain on solid.

118SAFETY
Once you repair or replace the original road
tire and reinstall it on the vehicle in place of
the compact spare tire, the TPMS will auto -
matically update, and the TPMS Warning
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.
TPMS Deactivation — If Equipped
The TPMS can be deactivated if replacing all
four wheel and tire assemblies (road tires) with
wheel and tire assemblies 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
20 minutes above 15 mph (24 km/h). The
TPMS will chime, the TPMS Warning Light will
flash on and off for 75 seconds and then remain
on.
Beginning with the next ignition cycle, the TPMS
will no longer chime or flash the TPMS Warning
Light. 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 20 minutes above 15 mph
(24 km/h). The TPMS will chime, the TPMS
Warning Light will flash on and off for
75 seconds and then turn off.

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 (including 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 the vehicle after overnight
parking for fuel, coolant, oil, or other fluid leaks.
Also, if gasoline fumes are detected or if fuel, or
brake fluid leaks are suspected, the cause
should be located and corrected immediately.
ALWAYS REMOVE THE EXISTING FLOOR
MAT FROM THE VEHICLE before
installing any other floor mat. NEVER install
or stack an additional floor mat on top of an
existing floor mat.
ONLY install floor mats designed to fit your
vehicle. NEVER install a floor mat that
cannot be properly attached and secured to
your vehicle. If a floor mat needs to be
replaced, only use a FCA approved floor
mat for the specific make, model, and year
of your vehicle.
ONLY use the driver’s side floor mat on the
driver’s side floor area. To check for inter -
ference, with the vehicle properly parked
with the engine off, fully depress the accel -
erator, the brake, and the clutch pedal (if
present) to check for interference. If your
floor mat interferes with the operation of
any pedal, or is not secure to the floor,
remove the floor mat from the vehicle and
place the floor mat in your trunk.
ONLY use the passenger’s side floor mat on
the passenger’s side floor area.
WARNING! (Continued)
ALWAYS make sure objects cannot fall or
slide into the driver’s side floor area when
the vehicle is moving. Objects can become
trapped under accelerator, brake, or clutch
pedals and could cause a loss of vehicle
control.
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 accel -
erator, 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 inter -
ference 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.

182STARTING AND OPERATING
VEHICLE LOADING
Certification Label
As required by National Highway Traffic Safety
Administration 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
increased durability does not necessarily
increase the vehicle'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.
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.

188STARTING AND OPERATING
Towing Requirements — Tires
Do not attempt to tow a trailer while using a
compact spare tire.
Do not drive more than 50 mph (80 km/h)
when towing while using a full size 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.
When replacing tires, refer to “Tires” in
“Servicing And Maintenance” for the 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
Do not interconnect the hydraulic brake
system or vacuum system of your vehicle
with that of the trailer. This could cause inad -
equate 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.
Trailer brakes are recommended for trailers
over 1,000 lbs (453 kg) and required for
trailers in excess of 2,000 lbs (907 kg).
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. For
four-wheel drive vehicles, make sure the
transfer case is not in NEUTRAL. Always,
block or "chock" the 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 :
GVWR
GTW
GAWR
Tongue weight rating for the trailer
hitch utilized.
WARNING! (Continued)
WARNING!
Do not connect trailer brakes to your
vehicle's hydraulic brake lines. It can over -
load your brake system and cause it to fail.
You might not have brakes when you need
them and could have an accident.
Towing any trailer will increase your stop -
ping distance. When towing, you should
allow for additional space between your
vehicle and the vehicle in front of you.
Failure to do so could result in an accident.

10. Place the deflated (flat) tire and compact
spare tire cover assembly in the rear cargo
area. Do not stow the deflated tire in the
compact spare tire location. Have the
full-sized tire repaired or replaced, as soon
as possible.
11. Stow the cable and wheel spacer before driving the vehicle. Reassemble the winch
handle extensions to form a “T” and fit the
winch T-handle over the drive nut. Rotate
the nut to the right until the winch
mechanism clicks at least three times.
NOTE:
Refer to the “Spare Tire Tools” section for
instructions on assembling the T-handle.
12. Stow the jack, jack handle and winch handle tools back in the stowage
compartment.
13. Check the compact spare tire pressure as soon as possible. Correct the tire pressure,
as required.Securing The Compact Spare Tire

1. Assemble the winch handle extensions to form a T-handle and fit the winch T-handle
over the drive nut. Rotate the nut to the left
until the winch mechanism stops turning
freely. This will allow enough slack in the
cable to allow you to pull the wheel spacer
out from under the vehicle.

2. Assemble the winch handle extensions to form the spare tire hook, and pull the wheel
spacer from under the vehicle. 3. Turn the compact spare tire so that the
valve stem is down, and place the tire into
the compact spare tire/cover assembly.
Slide the wheel spacer through the center of
the wheel and compact spare tire/cover
assembly, so that the two retainer tabs
snap out and engage the compact spare tire
cover on the opposite side.
WARNING!
A loose compact spare tire/cover assembly,
thrown forward in a collision or hard stop
could endanger the occupants of the vehicle.
Always stow the compact spare tire with the
cover assembly in the place provided.
CAUTION!
The winch mechanism is designed for use
with the winch T-handle only. Use of an air
wrench or other power tools is not
recommended and can damage the winch.
WARNING!
Verify that both retainer tabs of the wheel
spacer have been properly extended through
the center of the wheel and compact spare
tire/cover assembly. Failure to properly
engage both retainer tabs could result in loss
of the compact spare tire and cover
assembly, which will cause vehicle damage
and may cause loss of vehicle control and
serious personal injury.
CAUTION!
The compact spare tire/cover assembly must
be used when the compact spare tire is
stored. Failure to use this cover could
drastically reduce the life of the compact
spare tire.
