2014 Nissan Titan Crew Cab Owner's Manual - Page 310

DRIVING THE VEHICLE ENGINE PROTECTION MODE The engine has an engine protection mode to reduce the chance of damage if the coolant temperature becomes too high (for example, when climbing steep grades in high temperature with heavy loads, such as when towing a trailer). When the engine temperature reaches a certain level: ● The engine coolant temperature gauge will move toward the H position. ● Engine power may be reduced. ● The air conditioning cooling function may be automatically turned OFF for a short time (the blower will continue to operate). Engine power and, under some conditions, vehicle speed will decrease. Vehicle speed can be controlled with the accelerator pedal, but the vehicle may not accelerate at the desired speed. The transmission will downshift or upshift as it reaches prescribed shift points. You can also shift manually. As driving conditions change and engine coolant temperature is reduced, vehicle speed can be increased using the accelerator pedal, and air conditioning cooling function will automatically be turned back ON. If: 1. The engine coolant temperature is not reduced. 2. The air conditioning cooling function does not turn back ON. 3. The engine oil pressure low/engine coolant illumitemperature high warning light nates, this may indicate a malfunction. Move the vehicle off the road in a safe area and allow the engine to cool. If after checking the remains on, do not oil and coolant, the continue to drive and call a NISSAN dealer. The malfunction indicator light (MIL) may also come ON. If only it remains on, you do not need to have your vehicle towed, but have it inspected soon by a NISSAN dealer. See "Malfunction indicator light (MIL)" in the "Instruments and controls " section of this manual. WARNING Overheating can result in reduced engine power and vehicle speed. The reduced speed may be lower than other traffic, which could increase the chance of a collision. Be especially careful when driving. If the vehicle cannot maintain a safe driving speed, pull to the side of the road in a safe area. Allow the engine to cool and return to normal operation. See "If your vehicle overheats" in the "In case of emergency" section of this manual. CAUTION Running the engine with the engine oil pressure warning light on could cause serious damage to the engine almost immediately. Such damage is not covered by warranty. Turn off the engine as soon as it is safe to do so. Starting and driving 5-13
