Prepare your vehicle
Perform the pre-operation checks each time you use the vehicle to make sure it is in safe oper-
ating condition. Failure to inspect or maintain th e vehicle properly increases the possibility of an
accident or equipment damage. See page 5-1 for a list of pre-operation checks.
Prepare your load
Carrying heavy or over-sized loads can affect hand ling, stability, and cause the risk of overturns
or other accidents.
 Read “Loading” on page 6-12 before loading the cargo bed.
 Do not overload the vehicle or cargo bed.
 Refer to the labels on the vehicle for specific loading limits and recommended tire air pressure.
 Keep heavier objects and the load in general cent ered side to side, and as low and as far for-
ward in the cargo bed as possible.
 Secure cargo so that it will not shift – a loose load could change handling unexpectedly or be
thrown forward and strike occupants.
 This vehicle is not designed to tow or pull objects. Towing a trailer or pulling another vehicle or
other object will affect handling, stability, an d increase the risk of overturns and accidents.
Towing or pulling can also cause frame and vehicle damage.
