2009 DODGE GRAND CARAVAN wheel size

WARNING!Using a seat belt extender when not needed can
increase the risk of injury in a collision. Only use
when the lap belt is not long enough when it is worn
low and snug, and in the recommended seating
positions. Remove and store the extender when not
needed.
Supplemental Restraint System (SRS) - Airbags
This vehicle has airbags for both the driver and front
passenger as a supplement to the seat belt restraint
systems. The driver’s front airbag is mounted in the
center of the steering wheel. The passenger’s front airbag
is mounted in the instrument panel, above the glove
compartment. The words SRS AIRBAG are embossed on
the airbag covers.
NOTE:
The front airbags are certified to the Federal
regulations that allow less forceful deployment. The front airbags have a multistage inflator design. This
may allow the airbag to have different rates of inflation
that are based on collision severity and occupant size.
This vehicle may also be equipped with Supplemental
Side Airbag Inflatable Curtains (SABIC) to protect the
driver, front, and rear passengers sitting next to a win-
dow. If the vehicle is equipped with SABIC airbags, they
are located above the side windows and their covers are
also labeled: SRS AIRBAG.
NOTE:
Airbag covers may not be obvious in the interior
trim; but they will open to allow airbag deployment.
Airbag System Components
The airbag system consists of the following:
Occupant Restraint Controller (ORC)
Airbag Warning Light
Driver Airbag
THINGS TO KNOW BEFORE STARTING YOUR VEHICLE 63 2

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 opera-
tion or sensor damage may result when using re-
placement equipment that is not of the same size,
type, and/or style. Aftermarket wheels can cause
sensor damage. Do not use tire sealant from a can, or
balance beads if your vehicle is equipped with a
TPMS, as damage to the sensors may result.
26. Electronic Stability Program (ESP) Indicator Light
/ Brake Assist System (BAS) Warning Light The malfunction light for the Electronic Stabil-
ity Program (ESP) is combined with Brake
Assist System (BAS). The yellow “ESP/BAS
Warning Light” comes on when the ignition switch is turned to the “ON” position. They should go
out with the engine running. If the “ESP/BAS Warning
Light” comes on continuously with the engine running, a
malfunction has been detected in either the ESP or the
BAS system. If this light remains on after several ignition
cycles, and the vehicle has been driven several miles/
kilometers at speeds greater than 30 mph (48 km/h), see
an authorized dealer as soon as possible.

WARNING!
The Anti-Lock Brake System contains sophisti-
cated electronic equipment that may be suscep-
tible to interference caused by improperly in-
stalled, or high output radio transmitting
equipment. This interference can cause possible
loss of anti-lock braking capability. Installation of
such equipment should be performed by qualified
professionals.
Pumping of the anti-lock brakes will diminish
their effectiveness and may lead to an accident.
Pumping makes the stopping distance longer. Just
press firmly on your brake pedal when you need
to slow down or stop.
(Continued) WARNING! (Continued)

The Anti-Lock Brake System cannot prevent acci-
dents, including those resulting from excessive
speed in turns, following another vehicle too
closely, or hydroplaning. Only a safe, attentive,
and skillful driver can prevent accidents.
The capabilities of an ABS-equipped vehicle must
never be exploited in a reckless or dangerous
manner, which could jeopardize the user ’s safety
or the safety of others.
All vehicle wheels and tires must be the same size and
type, and tires must be properly inflated to produce
accurate signals for the computer.
346 STARTING AND OPERATING

WARNING!
Do not use a tire, wheel size or rating other than
that specified for your vehicle. Some combinations
of unapproved tires and wheels may change sus-
pension dimensions and performance characteris-
tics, resulting in changes to steering, handling, and
braking of your vehicle. This can cause unpredict-
able handling and stress to steering and suspen-
sion components. You could lose control and have
an accident resulting in serious injury or death.
Use only the tire and wheel sizes with load ratings
approved for your vehicle.
Never use a tire with a smaller load index or
capacity, than what was originally equipped on
your vehicle. Using a tire with a smaller load index
could result in tire overloading and failure. You
could lose control and have an accident.
(Continued) WARNING! (Continued)

Failure to equip your vehicle with tires having
adequate speed capability can result in sudden tire
failure and loss of vehicle control. CAUTION!
Replacing original tires with tires of a different size
may result in false speedometer and odometer read-
ings.
TIRE CHAINS
Use only compact chains, or other traction aids that meet
SAE type “Class S” specifications. Chains must be the
proper size for the vehicle, as recommended by the chain
manufacturer.
NOTE:
Do not use tire chains on a compact spare tire.
STARTING AND OPERATING 367 5

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 recommended
cold tire placard pressure. Once the low tire pressure
warning has been illuminated, the tire pressure must be
increased to the recommended cold tire placard pressure
in order for the “TPMS Warning Lamp” to be turned off.
The system will automatically update and the “TPMS
Warning Lamp” will extinguish once the updated tire
pressures have been received. The vehicle may need to be
driven for up to 20 minutes above 15 mph (25 km/h) to
receive this information.
For example, your vehicle may have a recommended
cold (parked for more than three hours) tire pressure of
35 psi (241 kPa). If the ambient temperature is 68°F (20°C)
and the measured tire pressure is 30 psi (207 kPa), a
temperature drop to 20°F (-7°C) will decrease the tire
pressure to approximately 26 psi (179 kPa). This tire
pressure is sufficiently low enough to turn on the “TPMSWarning Light.” Driving the vehicle may cause the tire
pressure to rise to approximately 30 psi (207 kPa), but the
“TPMS Warning Light” will still be on. In this situation,
the “TPMS Warning Light” will turn off only after the
tires have been inflated to the vehicle’s recommended
cold tire pressure value. CAUTION!

The TPMS has been optimized for the original
equipment tires and wheels. TPMS pressures have
been established 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. Aftermarket wheels can cause sensor dam-
age. Do not use aftermarket sealants or balance
beads if your vehicle is equipped with a TPMS, as
damage to the sensors may result. (Continued)

Gross Axle Weight Rating (GAWR)The GAWR is the maximum capacity of the front and rear
axles. Distribute the load over the front and rear axles
evenly. Make sure that you do not exceed either front or
rear GAWR.
WARNING!
Because the front wheels drive and steer the vehicle,
it is important that you do not exceed the maximum
front or rear GAWR. A dangerous driving condition
can result if either rating is exceeded. You could lose
control of the vehicle and have an accident.
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.
390 STARTING AND OPERATING

10. Lower the vehicle by turning the jack screw to the
left.
11. Finish tightening the lug nuts. Push down on the
wrench while tightening for increased leverage. Alternate
lug nuts until each nut has been tightened twice. The
correct wheel nut tightness is 95 ft lbs (130 N·m). If in
doubt about the correct tightness, have them checked
with a torque wrench by your authorized dealer or at a
service station.
12. Lower the jack to its fully-closed position.WARNING!
A loose tire or jack thrown forward in a collision or
hard stop could endanger the occupants of the ve-
hicle. Always stow the jack parts and the spare tire in
the places provided. Have the deflated (flat) tire
repaired or replaced immediately.
13. Place the deflated (flat) tire and compact spare tire
cover assembly. in the rear cargo area.
Do not stow the
deflated tire in the spare tire location. Have the full-
sized tire repaired or replaced, as soon as possible.
14. 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.
15. Stow the jack, jack handle and winch handle tools.
16. Check the compact spare tire pressure as soon as
possible. Correct the tire pressure, as required.Wheel Nuts
All wheel nuts should be tightened occasionally, to
eliminate the possibility of wheel studs being sheared or
the bolt holes in the wheels becoming elongated. This is
especially important during the first few hundred miles
