Setting The Clock In A Hummer H3

If you're into huge but lovely cars, then you've probably considered buying a Hummer H3. If it's your first time using this kind of car, then you might also wonder how to set up a time. Setting up the clock on a Hummer H3 varies depending on the car model.

Here's a step-by-step guide on how to set up a clock in a Hummer H3:

1. Turn On The Vehicle

Before you can use the accessories on your car, including the clock, you must first turn on the vehicle engine. You can also turn only on the accessory mode of your vehicle to use this.

2. Press The CONFIG Button

Newer Hummer H3 models have the CONFIG hard button. If your car happens to have this button, all you need to do is to press it. Other models don't have a CONFIG button, so you need to turn the volume knob to turn on the system.

3. Adjust The Time

To adjust the time on newer models with touch screens, you need to tap on the clock screen button. Search for the desired time zone, and it will automatically set the date and time of your car.

However, on models that have the "H" and "M" hard buttons, you will need to adjust the time manually. Push and hold these buttons to adjust the time. Push the H button to adjust the hour and the M button for the minute.

Have you experienced starting your car's engine, you're off to somewhere, and suddenly noticing that your car clock is displaying the wrong time? If you experienced this more often, then you better check for some issues. Here are some of the possible reasons that you need to look into why your car clock keeps on resetting:

Your car fuse is responsible for controlling the flow of current throughout your car's electrical components. You better check for some loose connections on your fuse if you experience your car clock resetting more often.

If there are no existing issues with the abovementioned causes, your car's wiring can be a problem. These wiring issues should be consulted with a professional mechanic since this can only be diagnosed using special tools.
