5.  As soon as the engine has cooled to its normal operating temperature, visually 
inspect the drive belts for damage or looseness. A loose belt reduces water 
pump efficiency.  
 
  
  WARNING- Be careful to keep your hands, hair, jewelry, and clothing clear of the 
running drive belt and other moving parts when inspecting the engine and radiator. 
Also check to see if the cooling fan is running, and inspect the water pump, radiator, 
and radiator hoses for leaks. Keep in mind, too, that if your vehicle is equipped with  
  an electric fan motor, it may start without warning any time the coolant temperature 
is high. If you find leaking coolant, a loose or missing drive belt, or an inoperable fan, 
turn off the engine immediately. 
 
6.  If no leaks are apparent and all other components appear to be operating 
properly with the engine cooled to its normal operating temperature; check the 
coolant level in the reservoir tank with the engine running. Add coolant to the 
reservoir tank if needed. At this point, if repairs are required, go to the nearest 
INFINITI retailer. See the IN CASE OF EMERGENCY section of your vehicle owner’s 
manual for additional information on overheating. 
 
NOTE – All INFINITI vehicles have an engine protection mode which helps reduce the 
chance of engine damage if the engine coolant reaches a specified temperature.

Passenger Vehicles – INFINITI cautions that you do not tow a trailer with the Q50, or Q60 
vehicles. 
 
 
1.   Maximum Trailer Weight values are calculated assuming a base 
vehicle with driver and any options required, to achieve the 
rating.  Additional passengers, cargo and/or optional equipment 
will add weight to the vehicle and reduce your vehicle’s 
maximum towing capacity and trailer tongue load. 
 
2.   In general, a weight-distributing hitch system (Class IV) should be 
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).
