Use the inside rear view mirror or
look back directly to determine the
actual distance of other vehicles
prior to changing lanes.
Do not scrape ice off the mirrorface; this may damage the sur- face 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.Side view mirror adjustment
Adjusting the side view mirrors:
1. Press either the L (driver's side) or R (passenger's side) button (1) to
select the side view mirror you
would like to adjust.
2. Use the mirror adjustment control switch (2) to position the selected
mirror up, down, left or right. The mirrors stop moving when
they reach the maximum adjust-
ing angles, but the motor contin-
ues to operate while the switch
is pressed. Do not press the
switch longer than necessary,
because this can damage the
motor.
Do not attempt to adjust the side view mirrors by hand, because
this can damage the motor.
