Maximum Front and Rear Axle
Weights
The weight of the cargo load must
be properly distributed over both the
front and rear axles. The “VIN,Weight Rating, and Greenhouse
Gas (GHG) Emissions Plate”
shows
the maximum weight that the front
axle can carry (front GAWR). It also
shows the maximum weight that the
rear axle can carry (rear GAWR).
The GVWR is the maximum
permissible loaded weight of the
vehicle and takes into account the
capabilities of the engine,
transmission, frame, springs,
brakes, axles and tires. Actual loads
at the front and the rear axles can
only be determined by weighing the
vehicle. This can be done at
highway weigh stations or other
such places. See your dealer for help. The cargo load should be
distributed on both sides of the
center line as equally as possible.
Tires
The tires on your truck must be of
the proper size and properly inflated
for the load that you are carrying.
The
“VIN, Weight Rating, and
Greenhouse Gas (GHG) Emissions
Plate” shows the originally equipped
tire size and recommended inflation
pressures.
For the vehicle plate location, see
Vehicle Identification Number (VIN)
0 353.
See “Tire Load and Inflation Table”
under Tire Pressure 0307.

and have the system repaired.
Even if a problem has occurred in
the ABS, the brakes will still work
as normal brakes. In this case,
the ABS has no influence on the
operation of the brake system.

78 Instruments and Controls
If this light comes on while driving, it
indicates that there is a malfunction
in the automatic transmission’s
electronic control system. If the
warning light is on, see your dealer
for service.
Automatic Transmission
Fluid Temperature
Warning Light
This light comes on briefly when the
engine control switch is in the ON
position as a check to show the light
is working. It should go out when
the engine is started.
The Automatic Transmission Fluid
(ATF) Temperature warning light
comes on if the ATF temperature is
high. This usually occurs when the
transmission is overfilled and maybe accompanied by leakage of fluid
from the transmission
breather hose.
If the light stays on, or comes on
while driving, slow down and pull off
the road. Stop the vehicle at a safe
place and put the vehicle in
P (Park). With the engine idling, wait
until the light goes off. If the light
goes off, you can drive the vehicle
again. Continuing to drive while this
light is on may damage the
transmission. While this light is on,
the transmission cannot operate in
all gears. If you attempt to shift
gears, the vehicle may not continue
to move. If you cannot drive to a
dealer immediately, have the vehicle
towed.
Caution
Driving with the ATF warning light
constantly on can cause serious
mechanical damage to the
automatic transmission.
See Automatic Transmission 0205.
Overdrive Off Light
This light should come on briefly
when the engine control switch is
turned on as a check to make sure
the light is working. It should go out
automatically.
This light comes on when the
overdrive off switch on the selector
lever is turned on. Overdrive will not
operate even when the automatic
transmission is in D, unless engine
speed is excessive.

Diesel Exhaust Fluid (DEF)
Gauge
With the engine control switch in the
ON position, this gauge indicates
the approximate quantity of DEF
remaining in the DEF tank. F means
the tank is full and E means the
tank is almost empty. When only
one green bar is showing, the DEF
tank is almost empty and should be
refilled soon. If the vehicle is driven
too long with only one bar, the green
will change to amber and additional
warnings and indicators will display.
