5-2 Lighting

The vehicle has a light sensor
located on the top of the instrument
panel. Do not cover this sensor
or the system will come on
whenever the ignition is on.
The system may also turn on the
headlamps when driving through a
parking garage, heavy overcast
weather, or a tunnel. This is normal.
There is a delay in the transition
between the daytime and nighttime
operation of the Daytime Running
Lamps (DRL) and the automatic
headlamp systems so that driving
under bridges or bright overhead
street lights does not affect the
system. The DRL and automatic
headlamp system will only be
affected when the light sensor sees
a change in lighting lasting longer
than the delay.If the vehicle is started in a dark
garage, the automatic headlamp
system comes on immediately. If it
is light outside when the vehicle
leaves the garage, there will
be a slight delay before the
automatic headlamp system
changes to the DRL. 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. SeeInstrument Panel
Illumination Control on page 5-5.

change. Hold it there until the
lane change is completed. If the
lever is briefly pressed and released,
the turn signal flashes three times.
