Instrument Cluster: 2021 GMC Yukon Dashboard Instructions
In the 2021 GMC Yukon, the instrument panel is where all the important information for the driver is kept. This makes sure that the driving experience is smooth and well-informed. The instrument cluster shows important data like speed, engine RPM, fuel levels, and the state of different vehicle systems. It does this by using a variety of digital displays and analog gauges. The instrument cluster’s intuitive layout and user-friendly design make the driver more aware and in control by making it easy to get to important information quickly and without being distracted. Whether drivers are navigating through traffic or going on long trips, the instrument panel is a key part of keeping them informed and focused on the road ahead, always putting safety and comfort first.

Software Information: Press the thumbwheel while Software Information is highlighted to display open-source software information.
Speedometer
The speedometer shows the vehicle’s speed in either kilometers per hour (km/h) or miles per hour (mph).
Odometer
The odometer shows how far the vehicle has been driven, in either kilometers or miles. The odometer is always displayed in the bottom of the Driver Information Center (DIC).
Trip Odometer
The trip odometer shows how far the vehicle has been driven since the trip odometer was last reset. The trip odometer is accessed and reset through the Driver Information Center (DIC).
Tachometer
The tachometer displays the engine speed in revolutions per minute (rpm). For vehicles with the Stop/Start system, when the ignition is on, the tachometer indicates the vehicle status. When pointing to AUTO STOP, the engine is off but the vehicle is on and can move. The engine could auto-start at any time. When the indicator points to OFF, the vehicle is off. When the engine is on, the tachometer will indicate the engine’s revolutions per minute (rpm). The tachometer may vary by several hundred rpm, during Auto Stop mode, when the engine is shutting off and restarting.
Fuel Gauge
When the ignition is on, the fuel gauge indicates how much fuel is left in the tank. There is an arrow near the fuel gauge pointing to the side of the vehicle the fuel door is on. When the indicator is empty, the low fuel light comes on. There still is a little fuel left, but the vehicle should be refueled soon. Here are three things that some owners ask about.
None of these show a problem with the fuel gauge:
- It takes a little more, or less fuel to fill up than the gauge indicated. For example, the gauge may have indicated the tank was half full, but it actually took a little more, or less than half the tank’s capacity to fill the tank.
- The gauge moves a little while turning a corner, speeding up or braking.
- The gauge takes a few seconds to stabilize after the ignition is turned on and goes back to empty when the ignition is turned off.
Engine Oil Pressure Gauge
The engine oil pressure gauge shows the engine oil pressure in kPa (kilopascals) or psi (pounds per square inch) when the engine is running. Oil pressure can vary with engine speed, outside temperature, coolant temperature, and oil viscosity. On some models, the oil pump will vary engine oil pressure according to engine needs. Oil pressure may change quickly as the engine speed or load varies. This is normal. If the oil pressure warning light or Driver Information Center (DIC) message indicates oil pressure outside the normal operating range, check the vehicle’s oil as soon as possible.
Caution
Lack of proper engine oil maintenance can damage the engine. Driving with the engine oil low can also damage the engine. The repairs would not be covered by the vehicle warranty. Check the oil level as soon as possible. Add oil if required, but if the oil level is within the operating range and the oil pressure is still low, have the vehicle serviced. Always follow the maintenance schedule for changing engine oil.
If the vehicle has a diesel engine, see the Duramax diesel supplement.
Engine Coolant Temperature Gauge
This gauge measures the temperature of the vehicle’s engine coolant. While driving under normal operating conditions, if the needle moves into the red warning area, the engine is too hot. Pull off the road, stop the vehicle, and turn off the engine as soon as possible.
Voltmeter Gauge
When the ignition is on, this gauge indicates the battery voltage. When the engine is running, this gauge shows the condition of the charging system. The gauge can transition from a higher to lower or a lower to higher reading. This is normal. If the vehicle is operating outside the normal operating range, the charging system light comes on. The voltmeter gauge may also read lower when in fuel economy mode. This is normal. Readings outside the normal operating range can also occur when a large number of electrical accessories are operating in the vehicle and the engine is left idling for an extended period. This condition is normal since the charging system is not able to provide full power at engine idle. As engine speeds are increased, this condition should correct itself as higher engine speeds allow the charging system to create maximum power. The vehicle can only be driven for a short time with the readings outside the normal operating range. If the vehicle must be driven, turn off all accessories, such as the radio and air conditioner. Readings outside the normal operating range indicate a possible problem in the electrical system. Have the vehicle serviced as soon as possible.
