exit the vehicle through the
window.
 If the door and window cannot
be opened due to the rising
water, remain calm, wait until
the water level inside the
vehicle rises to the point that
the water pressure inside of
the vehicle equals the water
pressure outside of the vehi-
cle and then open the door
after waiting for the rising
water to enter the vehicle, and
exit the vehicle. When the outside water level exceeds
half the height of the door, the
door cannot be opened from

tem

5328-1. Specifications
■Temperature A, B, C
The temperature grades are A
(the highest), B, and C, repre-
senting the tire’s resistance to
the generation of heat and its
ability to dissipate heat when
tested under controlled condi-
tions on a specified indoor labo-
ratory test wheel.
Sustained high temperature can
cause the material of the tire to
degenerate and reduce tire life, and
excessive temperature can lead to
sudden tire failure.
Grade C corresponds to a level of performance which all passenger
car tires must meet under the Fed-
eral Motor Vehicle Safety Standard
No. 109.
Grades B and A represent higher
levels of performance on the labo-
ratory test wheel than the minimum
required by law.
Warning: The temperature grades
of a tire assume tha
t it is properly
inflated and not overloaded.
Excessive speed, underinflation, or
excessive loading, either sepa-
rately or in combination, can cause
heat buildup and possible tire fail-
ure.
