2004 DODGE GRAND CARAVAN tire 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

NOTE: Extended heavy use of Traction Control may
cause the system to deactivate and turn on the TRAC and
the OFF indicators located in the instrument cluster.
This is to prevent overheating of the brake system and is
a normal condition. The system will remain disabled for
about 4 minutes until the brakes have cooled. The system
will automatically reactivate and turn off the TRAC and
the OFF indicators.
If your vehicle becomes stuck in mud, ice, or snow, turn
the Traction Control System OFF before attempting to
ªrockº the vehicle free. TIRE SAFETY INFORMATION
Tire Markings
NOTE:
² P(Passenger)-Metric tire sizing is based on U.S. design
standards. P-Metric tires have the letter ªPº molded
into the sidewall preceding the size designation. Ex-
ample: P215/65R15 95H.242 STARTING AND OPERATING

² European Metric tire sizing is based on European
design standards. Tires designed to this standard have
the tire size molded into the sidewall beginning with
the section width. The letter 9 P 9 is absent from this tire
size designation. Example: 215/65R15 96H
² LT(Light Truck)-Metric tire sizing is based on U.S.
design standards. The size designation for LT-Metric
tires is the same as for P-Metric tires except for the
letters ªLTº that are molded into the sidewall preced-
ing the size designation. Example: LT235/85R16. ² Temporary Spare tires are high pressure compact
spares designed for temporary emergency use only.
Tires designed to this standard have the letter ªTº
molded into the sidewall preceding the size designa-
tion. Example: T145/80D18 103M.
² High Flotation tire sizing is based on U.S. design
standards and begins with the tire diameter molded
into the sidewall. Example: 31x10.5 R15 LT. STARTING AND OPERATING 243

Tire Sizing Chart
EXAMPLE:
Size Designation:
P = Passenger car tire size based on U.S. design standards
( ....blank.... ( = Passenger car tire based on European design standards
LT = Light Truck tire based on U.S. design standards
T = Temporary Spare tire
31 = Overall Diameter in Inches (in)
215 = Section Width in Milimeters (mm)
65 = Aspect Ratio in Percent (%)
ÐRatio of section height to section width of tire.
10.5 = Section Width in Inches (in)
R = Construction Code
Ð 9 R 9 means Radial Construction.
Ð 9 D 9 means Diagonal or Bias Construction.
15 = Rim Diameter in Inches (in)244 STARTING AND OPERATING

Tire Identification Number (TIN)
The TIN may be found on one or both sides of the tire
however the date code may only be on one side. Tires
with white sidewalls will have the full TIN including
date code located on the white sidewall side of the tire. Look for the TIN on the outboard side of black sidewall
tires as mounted on the vehicle. If the TIN is not found on
the outboard side then you will find it on the inboard side
of the tire.
EXAMPLE:
DOT MA L9 ABCD 0301
DOT = Department of Transportation
ÐThis symbol certifies that the tire is in compliance with the U.S. Department of Transportation tire
safety standards, and is approved for highway use.
MA = Code representing the tire manufacturing location.(2 digits)
L9 = Code representing the tire size.(2 digits)
ABCD = Code used by tire manufacturer.(1 to 4 digits)
03 = Number representing the week in which the tire was manufactured.(2 digits)
Ð03 means the 3rd week.
01 = Number representing the year in which the tire was manufactured.(2 digits)
Ð01 means the year 2001.
ÐPrior to July 2000, tire manufacturers were only required to have 1 number to represent the year in
which the tire was manufactured. Example: 031 could represent the 3rd week of 1981 or 1991.246 STARTING AND OPERATING

Tire Loading and Tire Pressure
Tire Placard Location
NOTE: Some vehicles have a ªTire and Loading Infor-
mationº placard located on the driver's side ªBº pillar. Tire and Loading Information Placard
This placard tells you important information about the,
1) number of people that can be carried in the vehicle
2) the total weight your vehicle can carry
3) the tire size designed for your vehicle
4) the cold tire inflation pressures for the front, rear
and spare tires. STARTING AND OPERATING 247

Loading
The vehicle maximum load on the tire must not exceed
the load carrying capacity of the tire on your vehicle. You
will not exceed the tire's load carrying capacity if you
adhere to the loading conditions, tire size and cold tire
inflation pressures specified on the Tire and Loading
Information placard and the Vehicle Loading section of
this manual.
NOTE: Under a maximum loaded vehicle condition,
gross axle weight ratings (GAWR's) for the front and rear
axles must not be exceeded. For further information on
GAWR's, vehicle loading and trailer towing, see the
Vehicle Loading section of this manual. To determine the maximum loading conditions of your
vehicle, locate the statement ªThe combined weight of
occupants and cargo should never exceed XXX kg or XXX
lbs.º on the Tire and Loading Information placard. The
combined weight of occupants, cargo/luggage and
trailer tongue weight (if applicable) should never exceed
the weight referenced here.248 STARTING AND OPERATING
