The dome lamps will come on when you open a door
and will slowly dim to off when all doors are closed.
You can also turn the dome lamps on by turning the
thumbwheel, located next to the parking/headlamps
knob, all the way up. In this position, the dome lamps
will remain on whether a door is opened or closed.
You can use the DOME OVERRIDE button, located
below the parking/headlamp knob, to set the dome
lamps to come on automatically when a door is opened,
or remain off. To turn the lamps off, press the button
into the ªinº position. With the button in this position,
the dome lamps will remain off when the doors are
open. To return the lamps to automatic operation, press
the button again and return it to the ªoutº position. With
the button in this position, the dome lamps will come on
when you open a door.
Battery Run-Down Protection
This feature shuts off the dome, reading, glove box
and underhood lamps if they are left on for more than
20 minutes when the ignition is off. This will keep your
battery from running down.

and the temperature in the upper right corner of the
mirror face. The dual display can be turned on or off by
briefly pressing either the TEMP or COMP button.

the mirror.

2-46 Driver's Outside Auto-Dimming
Rearview Mirror
The driver's outside mirror will adjust for the glare of
headlamps behind you. This feature is controlled by the
on and off settings on the electrochromic mirror. See
ªElectrochromic Inside Rearview Mirror with Compass
and Temperature Displayº earlier in this section.
Convex Outside Mirror
Your passenger's side mirror is convex. A convex
mirror's surface is curved so you can see more from the
driver's seat.
CAUTION:
A convex mirror can make things (like other
vehicles) look farther away than they really are.
If you cut too sharply into the right lane, you
could hit a vehicle on your right. Check your
inside mirror or glance over your shoulder before
changing lanes.
Heated Outside Rearview Mirrors
The outside rearview mirrors have a defrost mode.
To turn on the defrost feature, press the rear window
defogger button. See ªRear Window Defoggerº in the
Index for further information.
