DRIVING THE VEHICLE ● If the engine is very hard to start because it is flooded, depress the accelerator pedal all the way to the floor and hold it. Crank the engine for 5-6 seconds. After cranking the engine, release the accelerator pedal. Crank the engine with your foot off the accelerator pedal by turning the ignition key to START. Release the key when the engine starts. If the engine starts, but fails to run, repeat the above procedure. 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 warning/engine coolant temperature high indicator illuminates, this may indicate a malfunction. Move the vehicle off the road in a safe area and allow the engine to cool. If after checkremains ing the oil and coolant, the on, do not continue to drive and call a NISSAN dealer. The malfunction indicator lamp 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 lamp" in the "Warning and indicator lights" section of this manual. CAUTION Do not operate the starter for more than 15 seconds at a time. If the engine does not start, turn the key off and wait 10 seconds before cranking again, otherwise the starter could be damaged. 4. Allow the engine to idle for at least 30 seconds after starting. Do not race the engine while warming it up. Drive at moderate speed for a short distance first, especially in cold weather. In cold weather, keep the engine running for a minimum of 2-3 minutes before shutting it off. Starting and stopping the engine over a short period of time may make the vehicle more difficult to start. 5-10 Starting and driving
