TRAILER TONGUE 
The tongue is the part of the trailer that extends forward to meet the tow vehicle, and it also carries 
the coupler assembly. Knowledge of the trailer minimum  and maximum  tongue load is critical as it 
can have a significant effect on the handling and capacity of the tow vehicle. Refer to your vehicle 
owner’s manual to view the maximum conventional trailer tongue load listed for your vehicle. Trailer 
tongue weight is the amount of downward pressure exerted onto the hitch ball. Keep the tongue 
load between 10-15% of the total trailer weight.  DO NOT exceed the maximum tongue load 
specification.  If the tongue weight is below the recommended amount, you must move some of the 
load forward or add weight to the front frame of the trailer. 
  
SAFETY CHAINS/CABLES 
Always use suitable safety chains/cables between the tow vehicle and the trailer. If the hitch 
should break or become disengaged for some reason, these chains/cables will provide an 
emergency connection between the vehicle and the trailer.  The ultimate combined breaking 
strength of the two chains must be equal to the gross weight of the towed vehicle(s). 
 
The chains/cables should be crossed under the trailer tongue and attached to the hitch or vehicle 
frame. Crossing the chains/cables under the tongue will help prevent the tongue from hitting the 
ground should the trailer become disconnected.  
Be sure to leave enough slack in the chains/cables to turn corners without binding; however, note 
that excessive slack will allow the chains/cables to drag on the ground.  
 
 WARNING- Do not use S-hooks for attaching the safety chains as they may become un-hooked 
while towing.  If the S-hook unhooks, the emergency chains/cables will become detached,  so if the 
tow hitch breaks or becomes disengaged, it will allow the trailer to completely break away causing 
property damage and possibly personal injury or death. The use of S-hooks is illegal in many states. 
 
 CAUTION- To avoid damage to the bumper and chains/cables when making a sharp turn, do not 
attach the chains/cables too close to the coupler.  Consult your trailer manufacturer for the proper 
location of the chain/cable attachment to the trailer. 
 
REAR VIEW MIRRORS 
 
 WARNING- In many cases, a trailer can block your rear vision when you are using only the 
standard INFINITI rear view and outside mirrors. Be careful when changing lanes or turning.  Using 
only these mirrors could cause an accident as they were not designed for towing. 
 
 “Extended” mirrors specifically designed for trailer towing should be used when your rearward 
vision is obstructed. Before using these mirrors, make certain that they comply with state and local 
regulations. Telescoping Tow Mirrors are available as an accessory for certain INFINITI vehicles. 
Contact your INFINITI retailer for details. 
 
SWAY CONTROL DEVICE 
Sudden maneuvers, wind gusts, and buffeting caused by other vehicles can affect trailer handling.  
Sway control devices may help control the pivoting motion between tow vehicle and trailer and 
make trailer towing easier on the driver. If you choose to use one, contact a reputable trailer hitch 
supplier to make sure the sway control device will work with the vehicle, hitch, trailer and the 
trailer’s brake system.

  WARNING - Towing can significantly alter the handling and performance characteristics of your 
vehicle. Moreover, it puts increased strain on the engine and drivetrain. Therefore, it is always a 
good idea to approach towing from the standpoint of safety — whether you are purchasing 
equipment or actually pulling the trailer.  
 
 WARNING- Always make sure your vehicle’s towing capacity is adequate for the trailer you 
intend to tow. Be certain that you have all of the proper equipment needed for safe towing, such  
as safety chains/cables, electric trailer brakes, electric trailer brake controller, breakaway switch, 
and extended rear view mirrors.  Make certain your equipment conforms to all federal, state or local 
regulations to help ensure against the possibility of a serious accident and personal injury or death. 
 
 
You should follow a more frequent maintenance 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 
 WARNING- 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 which could result in a serious accident, 
personal injury or death. Careful loading and balancing, and a weight distribution hitch and sway-
control device can help eliminate these problems. 
 
As mentioned earlier, conventional trailer tongue load must fall between 10-15% of the total trailer 
weight, or within the limits of the maximum trailer tongue load specified by the trailer 
manufacturer. 
 WARNING- Excessive trailer tongue load can actually push down the tow vehicle in back, lifting 
the front wheels to a point where traction, steering response, and braking may be severely reduced. 
which could result in an accident, personal injury or death. Too little trailer tongue load or negative 
load can lift the trailer tongue upwards on the trailer ball causing instability, which may lead to 
swaying, “tail wagging,” or jackknifing which could result in an accident, personal injury or death. 
 
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 load ratio is achieved.
