and adversely affect driver and passenger safety. Frequent inspection of

vehicle chassis components is recommended if the vehicle is subjected to

heavy off-road usage.

Power take off (PTO) capability (if equipped)

Some vehicles are equipped with Power Take Off (PTO) capability. These

vehicles have a special transmission case, internal components and

calibration for PTO usage.

The PTO can be used during mobile and stationary

continuous/intermittent applications.

Gasoline engine:

PTO operation is disabled while the vehicle is in Overdrive (the TCIL will

not be illuminated), in N (Neutral), during engine cranking. Transmission

upshift and downshift schedules will be reduced by about 15% and will

have a firmer shift feel during PTO mobile applications.

The PTO cannot be disabled while the transmission is in D (Drive)

(Overdrive position with Overdrive canceled), 2 (Second) or 1 (First).

Refer to the Body Builder’s Layout Book for recommended electrical

installation.

Diesel engine:

The Auxiliary Powertrain Control Module (APCM) will elevate the engine

speed to 1,200 RPM when in PTO mode. PTO operation will be disabled

in stationary drive idle conditions. For more information on the APCM

and PTO operation with the Diesel engine, refer to the APCM manual

supplied with your vehicle.

DRIVING THROUGH WATER

If driving through deep or standing water is unavoidable, proceed very

slowly especially if the depth is not known. Never drive through water

that is higher than the bottom of the hubs (for trucks) or the bottom of

the wheel rims (for cars). Traction or brake capability may be limited

and your vehicle may stall. Water may also enter your engine’s air intake

and severely damage your engine.

Once through the water, always dry the brakes by moving your vehicle

slowly while applying light pressure on the brake pedal. Wet brakes do

not stop the vehicle as quickly as dry brakes. Driving through deep

water where the transmission vent tube is submerged may allow

water into the transmission and cause internal transmission

damage.
