If you start your vehicle in a dark garage, the automatic headlamp system will come on immediately. Once you leave the garage, it will take about one minute for the automatic headlamp system to change to DRL if it is light outside. During that delay, the instrument panel cluster may not be as bright as usual. Make sure the instrument panel brightness control is in the full bright position. See Instrument Panel Brightness on page 3-19. Roof Mounted Off-Road Light Switch Lower Grille Off-Road Light Switch Off-Road Lamps The off-road lamps, if the vehicle has them, provide auxiliary lighting when the vehicle is used off road. These lamps are not intended to be used in place of existing vehicle lighting. The lamps are not to be used on any public street or highway and are to be covered when not in use. Check your state and local laws before installing or using any auxiliary lighting. In some states it may be necessary to remove the roof lamps when operating the vehicle on the highway. The switches for the off-road lamps are located in the center of the instrument panel below the climate controls. One switch is used for the front lower-grille mounted off-road lamps, if the vehicle has them, and the other switch is used for the roof-mounted off-road lamps, if the vehicle has them. To use the lamps, remove the covers from the lamps and press the switch to turn them on or off. An indicator light on the switch will turn on when the lamps are on. Notice: Turning on the off-road lamps before removing the lamp covers could damage the off-road lamps and the covers. Always remove the covers before turning on the off-road lamps. The off-road lamps remain on even after the ignition is turned off. The off-road lamp switch must be pressed to turn them off. 3-18
