2008 Nissan Towing Guide    15 Always make sure your vehicle’s towing capacity is adequate for the trailer you intend to tow. 
Buy or lease only quality equipment, and have it installed only by professionals. In addition, be 
certain that you have all of the equipment needed for safe towing, including safety 
chains/cables, electric trailer brakes, electric trailer brake controller, breakaway switch, 
extended rear view mirrors, and so on. All of these items have been discussed in a previous 
section of this guide.  
  With regard to vehicle maintenance, you should follow a more frequent schedule and 
check fluid levels, pressures, tire condition, etc., more often when on the road. See your 
vehicle owner’s manual for details. 
 
LOADING YOUR TRAILER 
Taking the time to load and balance your trailer properly will improve overall handling and 
minimize the strain on your tow vehicle. Incorrectly loaded trailers tend to sway or swing from 
side to side, upsetting vehicle handling. Careful loading and balancing can help eliminate 
these problems. 
  As mentioned earlier, conventional trailer tongue load must fall between 10-15% of the 
total trailer weight. King pin load — if using a 5th wheel or gooseneck trailer — must be 
between 15-25% of the total trailer weight.  
Excessive tongue/king pin load can actually 
push down the vehicle in back, lifting the front 
wheels to a point where traction, steering 
response, and braking are severely reduced. 
Insufficient tongue/king pin load can cause 
instability, which may lead to “tail wagging” or 
jackknifing. 
With this in mind, proper loading is extremely 
important. When loading a trailer, 60% of the  
total cargo weight should be positioned in the  
front portion of the trailer and 40% in the back. 
Then, the load should be adjusted until the proper 
tongue/king pin load ratio is achieved. 
  The trailer load should be balanced equally 
from side-to-side. Unequal side-to-side loading 
can negatively affect handling and braking. Once 
in place, all cargo should be firmly secured to 
prevent shifting. If the load should shift abruptly 
during braking or cornering, it could quickly affect
