CAUTION
Do not adjust the steering wheel
while the vehicle is moving. Doing
so may cause the driver to mishan-
dle the vehicle and an accident may
occur resulting in death or serious
injuries.
After adjusting the steering wheel,
try moving it up and down to make
sure it is locked in position.
Adjust the mirror so that you can just
see the side of your vehicle in the mir-
ror.
Be careful when judging the size or dis-
tance of any object seen in the outside
rear view mirror on the passenger ’s side
because it is a convex mirror. Any object
seen in a convex mirror will look smaller
and farther away than when seen in a flat
mirror.Vehicles with the auto anti
−glare inside
rear view mirror—On some models, when
the inside rear view mirror surface dark-
ens in “AUTO” mode, the outside rear
view mirror surface also darkens to re-
duce the reflection of the headlights of the
vehicle behind you. (For details, see “Auto
anti −glare inside rear view mirror” on page
146 in this Section.)
On some models, when you push the rear
window defogger switch, the heater panels
in the outside rear view mirrors will quick-
ly clear the mirror surface. (See “Rear
window and outside rear view mirror de-
foggers and windshield wiper de −icer” on
page 161 in Section 1 −4.)
CAUTION
Do not adjust the mirror while the
vehicle is moving. Doing so may
cause the driver to mishandle the
vehicle and an accident may occur
resulting in death or serious inju-
ries.
On some models, since the mirror
surfaces can get hot, do not touch
them when the defogger switch is
on.
