Many car owners limit themselves to only a basic view of the mileage, not even suspecting the depth of functionality laid down by the engineers Nissan. Correct interpretation of readings allows you to reduce maintenance and fuel costs, as well as extend the life of the engine and transmission. This manual will reveal all the secrets of menu management, display settings and system diagnostics through the standard interface.
Interface design and menu navigation
Main control on-board computer carried out through buttons on the steering wheel, which allows you not to be distracted from the road. There are keys on the right side of the steering wheel DISP (Display), UP (Up), DOWN (Down) and data reset button TRIP RESET. Click on DISP switches the main display modes, and the use of arrows allows you to go deeper into submenus.
System interface Murano Z50 intuitive, but has its own specifics when switching between modes. Depending on the configuration (SE, SL, Platinum), the display can be black and white or color TFT, which affects the readability of data in bright sunlight. The driver should be aware that some parameters are updated with a delay of several seconds to smooth out sudden changes.
- 🚗 Button
DISP— the main switch between the modes “Average consumption”, “Instantaneous consumption”, “Mileage” and “Travel time”. - ⚙️ Button
UP/DOWN- used to scroll through the list of available options within the selected section. - 🔘 Button
TRIP RESET— resets the current accumulated data (mileage, consumption, time) in the active window.
Analysis of fuel consumption and driving style
One of the most popular functions is monitoring fuel consumption, which is divided into three main types: current, average and general. Current consumption is displayed in real time and reacts to every press of the gas pedal, making it an ideal tool for learning to drive economically. If you press the gas sharply, the numbers can instantly jump to 25-30 liters, and when driving smoothly, drop to 5-7 liters.
Average fuel consumption is calculated since the last data reset and shows average operating efficiency engine for a specific period. It is this indicator that is most often used for comparison with the official data of the manufacturer. It is important to understand that it depends on the type of road (city, highway) and operating conditions, so you only need to compare it with similar conditions.
- 📉 Current consumption: shows consumption in liters per 100 km at a given second.
- 📊 Average consumption: average value over the entire mileage since reset (Trip A or Trip B).
- 🔋 Power reserve: the estimated distance that can be driven with the remaining fuel in the tank.
Fuel saving secrets
Constant monitoring instantaneous flow helps to develop the habit of “reading” the road. When you see the numbers drop as you take your foot off the gas pedal, you begin to instinctively plan to stop at the traffic lights in advance. This not only saves money, but also reduces wear and tear on the brake pads and engine system.
⚠️ Warning: Fuel consumption readings may be inaccurate when driving at a constant low speed (less than 10 km/h) or when the engine is idling in warm-up mode.
- 12-14 l/100km
- 14-16 l/100km
- 16-18 l/100km
- More than 18 l/100km
Display settings and information personalization
Owners Nissan Murano have the ability to fine-tune the appearance information display. In the settings menu you can change the brightness of the backlight, which is automatically adjusted by the light sensor, but often requires manual adjustment when driving at dusk or at night. Contrast settings are also available for better readability of text on a color screen.
Particular attention should be paid to the interface language. The system supports many languages, and sometimes after replacing the battery or resetting the settings, the language may change to English. To return to Russian, you need to go to Settings -> Language and select the appropriate option.
- 🌗Brightness: Adjustable manually or automatically via light sensor.
- 🌍 Language: choose between Russian, English and other available localizations.
- 🔔 Sound alerts: adjust the volume of warnings about an unfastened seat belt or an open door.
Additional Display Features
In the menu, you can activate the display of additional parameters such as outside temperature, tire pressure (if the TPMS system is connected to the screen) and fuel level. Some owners prefer to see only mileage and time on the main screen, hiding extra numbers.
How to reset your display to factory settings?
Go to the settings menu, select "Reset" or "Factory Settings", confirm the action. This will return the brightness and arrangement of elements to the default values, but will not affect the navigation data.
System diagnostics and error reading
Although full-time on-board computer is not a full-fledged diagnostic scanner, it is capable of displaying warnings about critical faults. When the "Check Engine" icon or other warning symbols appear on the display, the system records an error code. However, the standard menu often does not provide a decoding of these codes, limiting itself to a general description of the problem.
For in-depth diagnostics, you must use an external OBDII scanner connected to the connector under the steering column. The scanner reads error codes (DTCs) from memory ECU (engine control unit) and allows you to see them in text form. This is especially useful for warning lights related to safety systems or transmissions.
| Indicator | Description of the problem | Recommended Actions |
|---|---|---|
| Yellow Engine | Engine or eco system malfunction | Checking oxygen sensors, catalyst |
| Red Brake | Problem with the brake system | Immediate stop and check fluid level |
| Blue Temp | The engine is not warmed up | Driving in gentle mode until it warms up |
| Yellow Battery | Alternator or battery malfunction | Checking the voltage and alternator belt |
⚠️ Warning: If a "Check Engine" message appears on the screen or the light flashes, do not ignore it. Even if the car drives normally, this could indicate problems with the catalytic converter or ignition system, which can lead to costly repairs.
☑️ Diagnostics before the trip
Hidden functions and engineering menu
In the system Nissan Murano Z50 There are hidden engineering modes, access to which is usually closed to the average user. However, some advanced owners find ways to activate additional tests, such as checking all display segments or calibrating sensors. These features are useful when repairing or replacing the dashboard yourself.
One way to activate the hidden menu involves a combination of pressing the buttons on the steering wheel and the light switch, but you should be careful. Incorrect actions may result in a factory reset or, in rare cases, blocking some features.
- 🛠️ Display test: checks all screen segments for dead pixels.
- 🔋 Battery Test: Diagnose battery voltage in real time.
- 🔧 Sensor test: checking the operation of the temperature, speed and fuel level sensor.
Before entering the engineering menu, be sure to write down the current settings (brightness, language, volume), since resetting may return them to factory values.
Typical problems and methods for solving them
Sometimes users encounter that on-board computer stops updating data or shows incorrect values. This may be due to a low battery or a software glitch. In such cases, rebooting the system by disconnecting the battery terminal for 10-15 minutes often helps.
Another common problem is the indicators sticking or not responding to button presses. This may indicate wear on the steering wheel contact group or the need to replace the display itself.
