Warnings and Cautionsfor Using the Mirrors
WARNING
Be sure to look over your shoulder
before changing lanes.
Changing lanes without taking into
account the actual distance of a vehicle
in the convex mirror is dangerous. You
could have a serious accident. What
you see in the convex mirror is closer
than it appears.
Always return the outside mirrors to
the driving position before you start
driving.
Driving with the outside mirrors folded
in is dangerous. Your rear view will be
restricted, which could lead to an
unexpected accident.

(Vehicles with electric retractable
mirrors)
Do not touch the outside mirrors
while they are folding in and out.
Touching an outside mirror while it is
folding in or out is dangerous. Your
hands could get caught which could
cause an injury or the door mirror
could be damaged.
Use the switch to set the outside
mirrors.
Setting the outside mirrors manually is
dangerous. The outside mirrors will not
lock into place, which could obstruct
visibility.
Always operate the electric retractable
mirrors with the vehicle parked in a
safe place.
Operating the electric retractable
mirrors while driving is dangerous.
Wind pressure could damage the
outside mirrors, making it impossible
to return them to the driving position
and to see behind you.
Do not adjust the outside mirrors
while driving the vehicle.
Adjusting the outside mirrors while
driving the vehicle is dangerous as
doing so could distract your attention
from the road ahead and lead to an
accident.
CAUTION
(Vehicles with electric retractable
mirrors)
Operate the folding switch to fold in or
out the outside mirrors. If you unfold
the outside mirrors manually, they will
not be in a secured position and you
will be unable to check the view to the
rear of the vehicle.

set the parking brake, and make sure
the selector lever is in the P position.
Leaving the driver's seat without
switching the vehicle power off, setting
the parking brake, and shifting the
selector lever to the P position is
dangerous. Unexpected vehicle
movement could occur which could
result in an accident. In addition, if
your intention is to leave the vehicle for
even a short period, it is important to
switch the vehicle power position to
OFF, as leaving it in another position
will disable some of the vehicle's
security systems and run the lead-acid
battery down.
Radio waves from the key may affect
medical devices such as pacemakers.
Before using the key near people who
use medical devices, ask the medical
device manufacturer or your physician
if radio waves from the key will affect
the device.
Other than for an emergency
situation, do not attempt to stop the
hybrid system while driving the
vehicle.
If the hybrid system is stopped while
driving the vehicle, loss of brake power
