Maintenance and care
■How to initialize the tire pressure warning systemPark the vehicle in a s afe place and turn the power switch off.
Initialization cannot be perfo rmed while the vehicle is moving.
Adjust the tire inflation pressure to the specified cold tire i nflation
pressure level. ( P. 660)
Make sure to adjust the tire pre ssure to the specified cold tire infla-
tion pressure level. The tire pressure warning system will oper ate
based on this pr essure level.
Turn the power switch to ON mode.
Switch the multi-informatio n display to the screen.
(  P. 149)
Press or of the meter control switches, select “
(Vehicle Settings)”, and then press .
Press or of the meter contro l switches, select “Mainte-
nance System”, a nd then press .
Press or of the meter cont rol switches, select “TPMS”,
and then press .
Press and hold .
When initialization com-
pletes, a message is dis-
played on the multi-
information display and the
tire pressure warning light
illuminates.
◆Registering ID codes
The tire pressure warning valve and transmitter is equipped wit h a
unique ID code. When replacing a tire pressure warning valve an d

WARNING
■Maintenance of the tires
Each tire, including the spare (if provided), should be checked monthly
when cold and inflated to the inflation pressure recommended by the
vehicle manufacturer on the vehicle placard or tire inflation p ressure
label (tire and load information label). (If your vehicle has t ires of a dif-
ferent size than the size indicated on the vehicle placard or t ire inflation
pressure label [tire and load information label], you should de termine
the proper tire inflation p ressure for those tires.)
As an added safety feature, your vehicle has been equipped with a tire
pressure monitoring system (TPMS -tire pressure warning system) that
illuminates a low tire pressure telltale (tire pressure warning light) when
one or more of your tires is significantly under-inflated. Acco rdingly,
when the low tire pressure telltale (tire pressure warning ligh t) illumi-
nates, 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 lif e, and may
affect the vehicle’s handling and stopping ability.
Please note that the TPMS (tire pressure warning system) is not a sub-
stitute for proper tire maintenance, and it is the driver’s res ponsibility to
maintain correct tire pressure, even if under-inflation has not reached
the level to trigger illumination of the TPMS low tire pressure telltale (tire pressure warning light).
Your vehicle has also been equipped with a TPMS (tire pressure warn-
ing system) malfunction indicato r to indicate when the system is not
operating properly. The TPMS (tire pressure warning system) mal func-
tion indicator is combined with the low tire pressure telltale (tire pressure
warning light). When the system detects a malfunction, the tell tale will
flash for approximately one minute and then remain continuously illumi-
nated. This sequence will continue upon subsequent vehicle star t-ups
as long as the malfunction exists . When the malfunction indicator is illu-
minated, the system may not be able to detect or signal low tir e pres-
sure as intended.
TPMS (tire pressure warning system) malfunctions may occur for a vari-
ety of reasons, including the installation of replacement or alternate tires
or wheels on the vehicle that prevent the TPMS (tire pressure w arning
system) from functioning properly. Always check the TPMS (tire pres-
sure warning system) malfunction telltale after replacing one or more
tires or wheels on your vehicle to ensure that the replacement or alter-
nate tires and wheels allow the TPMS (tire pressure warning system) to
continue to function properly.
