2004 DODGE GRAND CARAVAN wheel size

transmission operating temperature exceeds acceptable
limits. This is done to prevent transmission damage due
to overheating.
ALL WHEEL DRIVE Ð IF EQUIPPED
This feature provides full time, on-demand, All Wheel
Drive (AWD). The system is automatic with no driver
inputs or additional driving skills required. Under nor-
mal driving conditions, the front wheels provide most of
the traction. If the front wheels begin to lose traction,
power is shifted automatically to the rear wheels. The
greater the front wheel traction loss, the greater the
power transfer to the rear wheels. CAUTION!All wheels must have the same size and type tires.
Unequal tire sizes must not be used. Unequal tire
size may cause failure of the power transfer unit
and/or the viscous coupling.
PARKING BRAKE
When the parking brake is applied with the ignition
switch on, the brake light in the instrument cluster will
turn on.
NOTE: This light only shows that the parking brake is
applied. It does not show the degree of brake application.
Before leaving the vehicle, make sure that the parking
brake is fully applied and place the gear selector in the STARTING AND OPERATING 235

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.
POWER STEERING
The standard power steering system will give you good
vehicle response and increased ease of maneuverability
in tight spaces. The system will provide mechanical
steering capability if power assist is lost.
If for some reason, the power assist is interrupted, it will
still be possible to steer your vehicle. Under these condi-
tions you will observe a substantial increase in steering
effort, especially at very low vehicle speeds and during
parking maneuvers.
NOTE: Increased noise levels at the end of the steering
wheel travel are considered normal and does not indicate
that there is a problem with the power steering system. WARNING!Continued operation with reduced power steering
assist could pose a safety risk to yourself and others.
Service should be obtained as soon as possible.
CAUTION!Prolong operation of the steering system at the end
of the steering wheel travel will increase the steering
fluid temperature and should be avoided when
possible. Damage to the power steering pump may
occur.240 STARTING AND OPERATING

WARNING!² 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 suspen-
sion dimensions and performance characteristics,
resulting in changes to steering, handling, and brak-
ing of your vehicle. This can cause unpredictable
handling and stress to steering and suspension com-
ponents. 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.
² Never use a tire with a smaller load index or capacity,
other 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.
² 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.
Alignment And Balance
Poor suspension alignment may result in:
² fast tire wear;
² uneven tire wear, such as feathering and one-sided
wear;
² vehicle pull to right or left.
Tires may also cause the vehicle to pull to the left or right.
Alignment will not correct this condition. See your dealer
for proper diagnosis.258 STARTING AND OPERATING

Improper alignment will not cause vehicle vibration.
Vibration may be a result of tire and wheel out-of-
balance. Proper balancing will reduce vibration and
avoid tire cupping and spotty wear.
ALL WHEEL DRIVE (AWD) Ð IF EQUIPPED
CAUTION!All Wheel Drive (AWD) vehicles must have the same
size and type tires on all wheel positions. Unequal
tire sizes must not be used. Unequal tire size may
cause failure of the power transfer unit and/or the
viscous coupling. TIRE PRESSURE MONITOR SYSTEM Ð IF
EQUIPPED
The Tire Pressure Monitor System (TPM) system uses
wireless technology with wheel rim mounted electronic
sensors to monitor tire pressure levels (EXCLUDING
THE SPARE TIRE). Sensors, mounted to each wheel as
part of the valve stem, transmit tire pressure readings to
a receiver located in the overhead console.
NOTE: The tire pressure monitoring system on your
vehicle will warn you when one of your tires is signifi-
cantly underinflated and when some combinations of
your tires are significantly underinflated. However, there
are other combinations of significantly underinflated
tires for which your tire pressure monitoring system may
not warn you. These other combinations are relatively
common, accounting for approximately half the instances
in which vehicles have significantly underinflated tires.
For example, your system may not warn you when both
tires on the same side or on the same axle of your vehicle STARTING AND OPERATING 259
5

CAUTION!The TPM system has been optimized for the original
equipment tires and wheels. TPM system pressures
have been established for the tire size equipped on
your vehicle. Undesirable operation or sensor dam-
age may result when using replacement equipment
that is not of the same size, type, and/or style.
After-market wheels can cause sensor damage. Do
not use tire sealant or balance beads if your vehicle
is equipped with TPM system as damage to the
sensors may result.
NOTE:
² The TPM system can inform the driver of a low tire
pressure condition of 28 psi [1.9 bars] (193 kPa) or less,
or high a tire pressure condition of 48 psi [3.3 bars]
(330 kPa) or more. ² The TPM system is not intended to replace normal tire
care and maintenance, nor to provide warning of a tire
failure or condition.
² The TPM system should not be used as a tire pressure
gauge while adjusting your tire pressure.
² The TPM system must be retrained after a tire rotation
or wheel rim mounted sensor replacement. See your
authorized dealer for service.
CAUTION!After inspecting or adjusting the tire pressure al-
ways reinstall the valve stem cap. This will prevent
moisture and dirt entry into the valve stem, which
could damage the wheel rim sensor.262 STARTING AND OPERATING

CAUTION!To avoid damage to your vehicle or tires, observe the
following precautions:
² Because of restricted chain clearance between tires and
other suspension components, it is important that only
chains in good condition are used. Broken chains can
cause serious damage. Stop the vehicle immediately if
noise occurs that could indicate chain breakage. Re-
move the damaged parts of the chain before further use.
² Install chains on the front wheels as tightly as possible
and then retighten after driving about 1
¤ 2
mile (0.8 km).
² Do not exceed 45 mph (70 km/h).
² Drive cautiously and avoid severe turns and large
bumps, especially with a loaded vehicle.
² Do not use on rear wheels of All Wheel Drive (AWD)
vehicles.
² Do not drive for prolonged period on dry pavement.
² Observe the tire chain manufacturer's instructions on
the method of installation, operating speed, and condi-
tions for use. Always use the lower suggested operating
speed of the chain manufacturer if different than the
speed recommended by the manufacture. NOTE: In order to avoid damage to tires, chains, and
your vehicle do not drive for a prolonged period of time
on dry pavement. Observe the tire chain manufacturer's
instructions on method of installation, operating speed,
and conditions for usage.
Always use the lower suggested operating speed if both
the chain manufacturer and vehicle manufacture suggest
a maximum speed. This notice applies to all chain
traction devices, including link and cable (radial) chains.
SNOW TIRES
Some areas of the country require the use of snow tires
during winter. Standard tires are of the all season type
and satisfy this requirement as indicated by the M+S
designation on the tire side wall.
If you need snow tires, select tires equivalent in size and
type to the original equipment tires. Use snow tires only
in sets of 4, failure to do so may adversely affect the
safety and handling of your vehicle.264 STARTING AND OPERATING
