There is a delay in the transition between the daytime and nighttime operation of the automatic lamp control system so that driving under bridges or bright overhead street lights does not affect the system. The automatic lamp control system will only be affected when the light sensor sees a change in lighting lasting longer than this delay. If the vehicle is started in a dark garage, the automatic lamp system turns on immediately. Once the vehicle exits the garage, it will take about 20 seconds for the automatic lamp 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 4‑14. To idle the vehicle with the system off, turn the ignition on and turn the exterior light switch to the off/on position. For vehicles first sold in Canada, the transmission must stay in P (Park) for this function or the parking brake must be set for vehicles with manual transmissions. Turn on the regular headlamps when they are needed. Fog Lamps For vehicles with fog lamps, the button is located on the instrument panel, to the right of the steering wheel. The ignition must be on to use the fog lamps. #: Press to turn the fog lamps on and off. An indicator light on the button comes on when the fog lamps are on. The parking lamps automatically turn on and off when the fog lamps are turned on and off. The fog lamps will turn off while the high-beam headlamps are turned on. Some localities have laws that require the headlamps to be on along with the fog lamps. 4-13
