Warning!
G
When closing the windows, make sure that
there is no danger of anyone being harmed
by the closing procedure.
The closing of the door windows can be im-
mediately halted by releasing the switch or,
if switch was pulled past the resistance
point and released, by either pressing or
pulling the respective switch.
The door windows are equipped with the ex-
press-close and automatic reversal func-
tion. If the window encounters an
obstruction that blocks its path in a circum-
stance where you pulled the switch past the
resistance point and released it to close the
window, the automatic reversal function will
stop the window and open it slightly.
If the window encounters an obstruction
that blocks its path in a circumstance where
you are closing the window by pulling and
holding the switch, by pressing and holding
button ‹ on the SmartKey, by pressing
and holding the lock button (vehicles with
KEYLESS-GO*) on an outside door handle,
or by pressing and holding button, on
the climate control panel, the automatic re-
versal function will not operate.
When leaving the vehicle, always remove the
SmartKey or SmartKey with KEYLESS-GO*
from the starter switch, take it with you, and
lock the vehicle. Do not leave children unat-
tended in the vehicle, or with access to an
unlocked vehicle. Unsupervised use of vehi-
cle equipment can cause an accident
and/or serious personal injury.

352 OperationTires and wheelsQuality grades can be found, where appli-
cable, on the tire sidewall between tread
shoulder and maximum section width. For
example:
All passenger car tires must conform to
federal safety requirements in addition to
these grades.
Treadwear
The treadwear grade is a comparative rat-
ing based on the wear rate of the tire when
tested under controlled conditions on a
specified government test course. For ex-
ample, a tire graded 150 would wear one
and one-half (1
1/2) times as well on the
government course as a tire graded 100.
The relative performance of tires depends
upon the actual conditions of their use,
however, and may depart significantly from the norm due to variations in driving
habits, service practices and differences in
road characteristics and climate.
Traction
The traction grades, from highest to low-
est, are AA, A, B, and C. Those grades rep-
resent the tire’s ability to stop on wet
pavement as measured under controlled
conditions on specified government test
surfaces of asphalt and concrete. A tire
marked C may have poor traction perfor-
mance.Temperature
The temperature grades are A (the high-
est), B, and C, representing the tire’s resis-
tance to the generation of heat and its
ability to dissipate heat when tested under
controlled conditions on a specified indoor
laboratory test wheel. Sustained high tem-
perature can cause the material of the tire
to degenerate and reduce tire life, and ex-
cessive temperature can lead to sudden
tire failure. The grade C corresponds to a
level of performance which all passenger
car tires must meet under the Federal Mo-
tor Vehicle Safety Standard No. 109.
Grades B and A represent higher levels of
performance on the laboratory test wheel
than the minimum required by law.

The traction grade assigned to this tire is
based on straight-ahead braking traction
tests, and does not include acceleration,
cornering, hydroplaning, or peak traction
characteristics.
