Loading Your Vehicle
-
DSI/KPA (COL3)
The Certification/Tire label is found on the rear edge of the driver’s door or
in the Incomplete Vehicle Document in the cab.
The label shows the size of your original tires and the inflation pressures
needed to obtain
the gross weight capacity of your vehicle. This is called the
GVWR (Gross Vehicle Weight Rating). The
GVWR includes the weight of
the vehicle, all occupants, fuel and cargo.
The CertificatiodTire label also tells you the maximum weights for the
front and rear axles, called Gross Axle Weight Rating (GAWR).
To find out
the actual loads
on your front and rear axles, you need to go to a weigh
station and weigh your vehicle. Your dealer can help
you with this. Be sure
to spread out your load equally on both sides of the centerline.
Never exceed the GVWR for your vehicle, or the GAWR for either the front
or rear axle.
And,
if you do have a heavy load, you should spread it out.
A CAUTION-:
In the case of a sudden stop or collision, things carried in the bed
of your truck could shift forward and come into the passenger \
area, injuring you and
others. If you put things in the bed of
your truck, you
should make sure they are properly secured.

WATER
IN
FUEL
If the light comes on at any other time, use this chart. This light also should
come on briefly when
you start your engine,
as
a check. If it
doesn’t, have it fixed
so it will be there to
let you know if you
ever do get water in
your fuel.
If you drive when this warning light is on, you can damage your
fuel injection system and your engine.
If the light comes on right
after you refuel,
it means water was pumped into your fuel tank.
Turn
off your engine immediately. Then, have the water drained
at once.
“WATER IN FUEL” LIGHT CHART
Problem Recommended Action
Light comes on intermittently. Drain water from fuel filter.
Light stays on:
1. At temperatures above freezing.
2. At temperatures below freezing.
3. Immediately after refueling -

immediately.
If no
water can be drained and light stays
on, see your dealer for assistance.
Drain fuel filter immediately.

water can be drained-water may
be frozen. Open the air bleed valve

NOTICE:
Don’t let anyone tell you that underinflation or overinflation is
all right. It’s not.
If’ your tires don’t have enough air
(underinflation)
you can get:
0 Too much flexing
Too much heat
0 Tire overloading
Bad wear
Bad handling
0 Bad fuel economy.
If your tires have too much air (overinflation), you can get:
Unusual wear
Bad handling
Rough ride
Needless damage from road hazards.
When to Check
Check your tires once a month or more. Also, check the tire pressure of the
spare tire.
How to Check
Use a good quality pocket-type gage to check tire pressure. Simply looking
at the tires will not tell you the pressure, especially
if you have radial tires
- which may look properly inflated even if they’re underinflated.
If your tires have valve caps, be sure to put them back on. They help prevent
leaks by keeping out dirt and moisture.
Tire Inspection and Rotation
Tires should be inspected every 6,000 to 8,000 miles (10 000 to 13 000 km)
for any signs of unusual wear. If unusual wear is present, rotate your tires as
soon as possible and check wheel alignment. Also check for damaged tires
or wheels. See “When it’s Time for New Tires” and “Wheel Replacement”
later in this section for more information.
If your vehicle has dual rear
wheels, also see
“Dual Tire Operation” later in this section.
