Hummer 2007 H3 - Manual (Page 166)

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 167.
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.
