In an Emergency
7. Start the engine of the vehicle providing the jump
start and let the engine run for a few minutes to
charge the batteries of the other vehicle.
NOTICE
Do not crank the engine for more than 30 sec-
onds at a time during any of the following proce-
dures. Wait two minutes after each try to allow
the starter to cool. Failure to do so could cause
starter damage.
8. Attempt to start the engine of the vehicle with the
batteries receiving the charge.
9. When the engine starts, let it idle for a few min-
utes.
WARNING
Do the next step exactly as instructed and do not
allow the clamps of one cable to touch the
clamps of the other cable. Otherwise, a spark

severe personal injury from explosion or acid
burns.

Towing

WARNING
Do not tow an unbraked vehicle if the combined
weight of both vehicles is more than the sum of
the gross axle weight ratings (GAWR) of the tow-
ing vehicle. Otherwise brake capacity will be in-
adequate, which could result in personal injury or
death.
17.3
IMPORTANT: When it is necessary to tow the
vehicle, make sure the instructions below are
closely followed to prevent damage to the ve-
hicle.
NOTE: Towing rules and regulations vary from
federal, state, local, and transit authority. These
laws must be followed when towing the vehicle.
Front Towing Hookup
NOTICE
The vehicle should never be towed from the rear.
The gross axle weight rating (GAWR) of the front
axle may not be sufficient to support the in-
creased load when towing from the rear. This
could damage the front axle.
1. Disconnect the battery ground cables.
NOTICE
Failure to remove the axle shafts when towing
the vehicle with the rear wheels on the ground
could result in damage to the transmission and
other parts.
2.
Remove the drive axle shaft.
IMPORTANT: Cover the ends of the hubs with
metal plates or plywood cut to fit the axle open-
ing, and drilled to fit the axle shaft studs. This
prevents lubricant from leaking out and will keep
contaminants from getting into and damaging
the wheel bearings and axle lubricant.
NOTICE
Failure to protect the frame rails from the chains
could cause damage, leading to eventual frame
failure.
3. Remove the bumper.
4. Attach the towing device. Due to the many vari-
ables that exist in towing, positioning the lifting
and towing device is the sole responsibility of the
towing-vehicle operator.
5. Lift the vehicle and secure the safety chains. If
extra towing clearance is needed, remove the
front wheels.
