Operating your vehicle with a light load means:
•
The total weight of occupants in your vehicle is less
than the total seating capacity number your vehicle
was designed to carry multiplied by 150 lbs (68 kg).
The total seating capacity number is on the Tire
and Loading Information label.
•
No more than 200 lbs (91 kg) of cargo, which must
be secured in the cargo area.
•
No trailer is attached to your vehicle.
•
You have not added any additional equipment to
your vehicle, like a truck cap or tool box.
The vehicle load capacity and the rear axle load
capacity are reduced when the tire pressure is lowered
to the amount recommended for improved ride.
Before operating your vehicle with passengers or cargo
greater than a light-load, you must inflate the rear
tires to the recommended cold tire pressure shown on
the Tire and Loading Information Label. See Loading
Your Vehicle on page 4-50.
Dual Tire Operation
When the vehicle is new, or whenever a wheel, wheel
bolt or wheel nut is replaced, check the wheel nut torque
after 100, 1,000 and 6,000 miles (160, 1 600 and
10 000 km) of driving. For proper torque and wheel nut
tightening information, see Removing the Spare Tire
and Tools on page 5-93.
The outer tire on a dual wheel setup generally wears
faster than the inner tire. Your tires will wear more
evenly and last longer if you rotate the tires periodically,
see Tire Inspection and Rotation on page 5-83. Also
see Scheduled Maintenance on page 6-4.

CAUTION:
If you operate your vehicle with a tire that is
badly underinflated, the tire can overheat. An
overheated tire can lose air suddenly or catch
fire. You or others could be injured. Be sure all
tires (including the spare) are properly inflated.
See Inflation - Tire Pressure on page 5-79, for
information on proper tire inflation.
