INTERIOR MIRROR
The interior rear view mirror has two pivot points on the support arm
which lets you adjust the mirror UP or DOWN and from SIDE to SIDE.
WARNING:Do not adjust the mirror while the vehicle is in
motion.
Automatic dimming interior rear view mirror
Your vehicle is equipped with an
interior rear view mirror and a
driver’s side exterior mirror that
have auto-dimming function. The
electronic day/night mirrors will
change from the normal (high
reflective) state to the non-glare
(darkened) state when bright lights (glare) reach the interior mirror.
When the interior mirror detects bright light from behind the vehicle, the
interior rear view mirror and the driver’s side exterior mirror will
automatically adjust (darken) to minimize glare.
The mirrors will automatically return to the normal state whenever the
vehicle is placed in R (Reverse) to ensure a bright clear view when
backing up.
Do not block the sensors on the front and back of the interior
rear view mirror since this may impair proper mirror
performance.
Do not clean the housing or glass of any mirror with harsh
abrasives, fuel or other petroleum-based cleaning products.
Note:If equipped with a rear view camera, a video image will be
displayed in the mirror or the navigation system display (if equipped)
when the vehicle is put in (R) reverse. Refer to theDrivingchapter.

CHANGING THE TIRES
If you get a flat tire while driving, do not apply the brake heavily.
Instead, gradually decrease your speed. Hold the steering wheel firmly
and slowly move to a safe place on the side of the road.
Note:The tire pressure monitoring system (TPMS) indicator light will
illuminate when the spare tire is in use. To restore the full functionality
of the monitoring system, all road wheels equipped with tire pressure
monitoring sensors must be mounted on the vehicle.
Have a flat serviced by an authorized dealer in order to prevent damage
to the TPMS sensors, refer toTire pressure monitoring system
