Extended exposure to high temperatures, especially when in direct sunlight may result in the display becoming inoperative. Under these conditions, it may be normal for the display to shut down to prevent permanent damage to the circuitry. Display should return to normal operating condition when temperatures cool.

Malfunctions may include a flickering or distorted image or a blank screen.

Using a dry cloth to clean the instrument panel in the area of the Information Display may cause the screen to flicker due to static buildup/discharge. The owner manual recommends using a microfiber cloth dampened with water to remove dust and dirt from the instrument panel.
