INFINITI retailer. See the IN CASE OF EMERGENCY section of your vehicle owner’s 
manual for additional information on overheating.

Also commonly called a drawbar. 
  
1   Maximum Trailer Weight values are calculated assuming a base 
vehicle with driver and any options required, to achieve the

will add weight to the vehicle and reduce your vehicle’s 
maximum towing capacity and trailer tongue load.

used when towing over 5,000 lbs. 
 
3   Most states require a separate braking system on trailers with a 
loaded weight above a specific amount. Check local ordinances.  
7-pin connector trailer wire harnesses are required for use with 
trailer brakes (available separately).
