Side view mirrors
ONX4050009
Your vehicle is equipped with both left-
hand and right-hand Side view mirrors.
The mirrors can be adjusted remotely
with the mirror adjustment control
switch. The side view mirrors can be
folded manually to help prevent damage
when going through an automatic car
wash or when passing through a narrow
street.
The right Side view mirror is convex.
Objects seen in the mirror are closer than
they appear.
Use the inside rear view mirror or look
back directly to determine the actual
distance of other vehicles prior to
changing lanes.
Make sure to adjust the Side view mirrors
to your desired position before you begin
driving.
WARNING
Do not adjust or fold the side view
mirrors while driving. This may cause
loss of vehicle control resulting in an
accident.
NOTICE
• Do not scrape ice off the mirror face;
this may damage the surface of the
glass.
• If the mirror is jammed with ice, do
not adjust the mirror by force. Use an
approved spray de-icer (not radiator
antifreeze) spray, or a sponge or soft
cloth with very warm water, or move
the vehicle to a warm place and
allow the ice to melt.
• Do not clean the mirror with harsh
abrasives, fuel or other petroleum
based cleaning products.

• After you pass through a tollgate on a
highway (or motorway), Navigation-
based Smart Cruise Control will
operate based on the first lane. If
you enter one of the other lanes,
Navigation-based Smart Cruise
Control may not operate properly.
• The vehicle will accelerate if the
driver depresses the accelerator
pedal while Navigation-based Smart
Cruise Control is operating, and
the function will not decelerate the
vehicle. However, if the accelerator
pedal is depressed insufficiently, the
vehicle may decelerate.
• If the driver accelerates and
releases the accelerator pedal while
Navigation-based Smart Cruise
Control is operating, the vehicle may
not decelerate sufficiently or may
rapidly decelerate to a safe speed.
• If the curve is too large or too small,
Navigation-based Smart Cruise
Control may not operate.
Information
• The time gap could occur between
the navigation’s guidance and when
Navigation-based Smart Cruise Control
operation starts and ends.
• The speed information on the cluster
and navigation may differ.
• Even if you are driving at a speed lower
than Smart Cruise Control set speed,
acceleration may be limited by the
curve sections ahead.
• If Navigation-based Smart Cruise
Control is operating while leaving the
main road to enter an interchange,
junction, rest area, etc., the function
may operate for a certain period of
time.
• Deceleration by Navigation-based
Smart Cruise Control may feel it is not
sufficient due to road conditions such
as uneven road surfaces, narrow lanes,
etc.
