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 ensure that the GVWR has not been ex-
ceeded. 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 or rear axles has been exceeded, but the total
load is within the specified GVWR. If so, weight must be
shifted from front to rear, or rear to front, as appropriate
until the specified weight limitations are met. Store the
heavier items down low and be sure that the weight is
distributed equally. Stow all loose items securely before
driving.

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
“Tires–General Information” in this section.
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 “Tires–General Infor-
mation” in this section.
When replacing tires, refer to “Tires–General Informa-
tion” in this section. 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.
Trailer brakes are recommended for trailers over
1,000 lbs (454 kg) and required for trailers in excess of
2,000 lbs (907 kg).
388 STARTING AND OPERATING

bugs, leaves, etc. If dirty, clean by gently spraying water
from a garden hose vertically down the face of the
condenser.
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
engine coolant (antifreeze) from the radiator drain cock.
If the cap is sealing properly, the engine coolant (anti-
freeze) will begin to drain from the coolant recovery
bottle. DO NOT REMOVE THE COOLANT PRESSURE
CAP WHEN THE COOLING SYSTEM IS HOT.Cooling System — Drain, Flush, And Refill
If the engine coolant (antifreeze) 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 the old engine coolant (antifreeze).
Refer to the “Maintenance Schedule” in Section 8 for the
proper maintenance intervals.
Selection Of Coolant
Use only the manufacturer’s recommended engine cool-
ant (antifreeze). Refer to “Fluids, Lubricants, and Genu-
ine Parts” in this section for the correct fluid type.

450 MAINTAINING YOUR VEHICLE

•Change your engine oil more often if you drive your
vehicle off-road for an extended period of time.
•Under no circumstances should oil change intervals
exceed 6,000 miles (10,000 km) or 6 months, whichever
comes first.
Your authorized dealer will reset the oil change indicator
message after completing the scheduled oil change. If this
scheduled oil change is performed by someone other
than your authorized dealer the message can be reset by
referring to the steps described under ”Electronic Vehicle
Information Center” in Section 4 of this manual.
At Each Stop for Fuel
•Check the engine oil level about 5 minutes after a fully
warmed engine is shut off. Checking the oil level while
the vehicle is on level ground will improve the accu-
racy of the oil level reading. Add oil only when the
level is at or below the ADD or MIN mark.
•Check the windshield washer solvent and add if
required.
Once a Month
•Check tire pressure and look for unusual wear or
damage.
•Inspect the battery and clean and tighten the terminals
as required.
•Check the fluid levels of coolant reservoir, brake
master cylinder, power steering and transmission
(4.7L and 5.7L engines) and add as needed.
•Check all lights and other electrical items for correct
operation.
At Each Oil Change
•Change the engine oil filter.
•Inspect the brake hoses and lines.
