Electric Chromic Mirror (ECM)
(if equipped)
The electric rearview mirror automati-
cally controls the glare from the head-
lamp of the vehicle behind you in
nighttime or low light driving condi-
tions.
When the engine is running, the
glare is automatically controlled by
the sensor mounted in the rearview
mirror. The sensor detects the light
level around the vehicle, and auto-
matically adjusts to control the head-
lamp glare from vehicles behind you.
Whenever the shift lever is placed in
R (Reverse), the mirror will automat-
ically go to the brightest setting in
order to improve the driver’s view
behind the vehicle.
To operate the electric rearview
mirror:
• Press the ON/OFF button (1) to
turn the automatic dimming func-
tion off. The mirror indicator light
will turn off.
Press the ON/OFF button (1) to
turn the automatic dimming func-
tion on. The mirror indicator light

tion whenever the ignition switch or
the Engine Start/Stop button is in
the ON position.
Outside rearview mirror
Be sure to adjust mirror angles
before driving.
Your vehicle is equipped with both
left-hand and right-hand outside
rearview mirrors.
The mirror can be adjusted remotely
with the remote switch.
The mirrors can be folded to prevent
damage during an automatic car
wash or when passing through a nar-
row street.
