increased load on the engine and cooling system, so monitor your coolant 
temperature gauge and automatic transmission fluid temperature gauge (if 
equipped) carefully. At the first sign of overheating, pull to the side of the road. See IF 
YOUR ENGINE OVERHEATS later in this section for more information. 
 
HILLS – DOWNGRADES 
 
 WARNING- While going downhill, the weight of the trailer pushing on the tow vehicle 
may decrease overall stability, and may deteriorate overall handling characteristics.  
The vehicle may handle unpredictably which could cause a loss of vehicle control 
resulting in an accident, property damage, serious injury or death.  Therefore, to 
maintain adequate control, reduce your speed and shift to a lower gear and apply 
the braking in short bursts. If your vehicle is equipped with Tow Mode, see your vehicle 
owner’s manual for information about the use of this function. 
 
  WARNING- Avoid long or repeated use of the brakes when descending a hill, as this 
reduces their effectiveness and could cause overheating which could result in 
damage to your brake components or unable to slow to a safe speed. Shifting to a 
lower gear instead provides “engine braking” and reduces the need to brake as 
frequently. 
HIGH-ALTITUDE PERFORMANCE 
An engine will lose about 4% of its performance for every 1,000 feet above sea level 
that you travel. If you will be towing in high altitudes, it is a good idea to allow more 
time than usual due to the engine’s reduced performance. 
 
While towing a trailer, do not use the following systems (if so equipped): 
— ProPILOT Assist 
— the Lane Departure Warning (LDW) system 
— the Lane Departure Prevention (LDP) system 
— the Blind Spot Warning (BSW) system 
— the Blind Spot Intervention® (BSI) system 
— the Back-up Collision Intervention (BCI) system 
— the Intelligent Cruise Control (ICC) system 
— the Distance Control Assist (DCA) system 
— the Forward Emergency Braking (FEB) with pedestrian detection system 
— the Predictive Forward Collision Warning (PFCW) system. 
 
INTELLIGENT CRUISE CONTROL 
 
  WARNING- In order to maintain a safe distance to the vehicle ahead to avoid the 
possibility of accidents, property damage, serious injury or death.  INFINITI recommends 
not to use the Intelligent Cruise control (ICC) system while towing a trailer or other 
vehicle.   In certain road conditions when your vehicle is towing, the ICC sensor may 
not detect a vehicle ahead.  If the ICC sensor cannot detect the reflector on the 
vehicle ahead, the ICC system may not maintain the selected distance which could 
cause an accident, property damage, or death.
