What to do in an emergency6 5TIRE PRESSURE MONITORING SYSTEM (TPMS)(1) Low Tire Pressure Indicator
(2) Low Tire Pressure Position
Indicator
(3) TPMS Malfunction Indicator
Each tire, including the spare, should
be checked monthly when cold and
inflated to the inflation pressure rec-
ommended by the vehicle manufac-
turer on the vehicle placard or tire
inflation pressure label. (If your vehi-
cle has tires of a different size than
the size indicated on the vehicle
placard or tire inflation pressure
label, you should determine the
proper tire inflation pressure for
those tires.)As an added safety feature, your
vehicle has been equipped with a
Tire Pressure Monitoring System
(TPMS) that illuminates a low tire
pressure indicator and a low tire
pressure position indicator when one
or more of your tires is significantly
under-inflated. Accordingly, when the
low tire pressure indicator and a low
tire pressure position indicator illumi-
nate, you should stop and check your
tires as soon as possible, and inflate
them to the proper pressure. Driving
on a significantly under-inflated tire
causes the tire to overheat and can
lead to tire failure. Under-inflation
also reduces fuel efficiency and tire
tread life, and may affect the vehi-
cle’s handling and stopping ability.
Please note that the TPMS is not a
substitute for proper tire mainte-
nance, and it is the driver’s responsi-
bility to maintain correct tire pres-
sure, even if under-inflation has not
reached the level to trigger illumina-
tion of the TPMS low tire pressure
and position indicators.Your vehicle has also been equipped
with a TPMS malfunction indicator to
indicate when the system is not
operating properly. The TPMS mal-
function indicator is provided by a
separate indicator, which displays
the symbol "TPMS" when illuminat-
ed. When the malfunction indicator is
illuminated, the system may not be
able to detect or signal low tire pres-
sure as intended. TPMS malfunc-
tions may occur for a variety of rea-
sons, including the installation of
replacement or alternative tires or
wheels on the vehicle that prevent
the TPMS from functioning properly.
Always check the TPMS malfunction
indicator after replacing one or more
tires or wheels on your vehicle to
ensure that the replacement or alter-
native tires and wheels allow the
TPMS to continue to function proper-
ly.

associated with the maximum
load the tire can carry.

Wheel size designation
Wheels are also marked with impor-
tant information that you need if you
ever have to replace one. The follow-
ing explains what the letters and
numbers in the wheel size designa-
tion mean.
Example wheel size designation:
5.5JX14
5.5 - Rim width in inches.
J - Rim contour designation.
14 - Rim diameter in inches.Tire speed ratings
The chart below lists many of the dif-
ferent speed ratings currently being
used for passenger cars. The speed
rating is part of the tire size designa-
tion on the sidewall of the tire. This
symbol corresponds to that tire's
designed maximum safe operating
speed.
3. Checking tire life (TIN : Tire
Identification Number) Any tires that are over 6 years, based
on the manufacturing date, tire
strength and performance, decline
with age naturally (even unused
spare tires). Therefore, the tires
(including the spare tire) should be
replaced by new ones. You can find
the manufacturing date on the tire
sidewall (possibly on the inside of the
wheel), displaying the DOT Code.
The DOT Code is a series of num-
bers on a tire consisting of numbers
and English letters. The manufactur-
ing date is designated by the last four
digits (characters) of the DOT code.
DOT : XXXX XXXX OOOO
The front part of the DOT means a
plant code number, tire size and
tread pattern and the last four num-
bers indicate week and year manu-
factured.
For example:
DOT XXXX XXXX 1605 represents
that the tire was produced in the 16th
week of 2005.
S 112 mph (180 km/h)
T 118 mph (190 km/h)
H 130 mph (210 km/h)
V 149 mph (240 km/h)
Z Above 149 mph (240 km/h)
