or other accidents.
 Read “Loading” on page 7-12 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-

 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.
