Interior features
■The wireless charger can be operated when
The power switch is in ACCESSORY or ON mode.
■ Usable portable devices
Qi standard wireless charge standard can be used on compatible devices.
However, not all Qi standard devices and compatibility are guaranteed.
Starting with mobile phones and smart phones , it is aimed for low power elec-
trically supplied portable devices of no more than 5W.
■ When covers and accessories are attached to portable devices
Do not charge in situations where cover and accessories not able to handle
Qi are attached to the portable device. Depending on the type of cover and
accessory, it may not be possible to charge. When charging is not performed
even with the portable device placed on the charge area, remove the cover
and accessories.
■ While charging, noise enters the AM radio
Turn off the wireless charger and confirm that the noise has decreased. If the
noise decreases, continuously pushing the power supply switch of the wire-
less charger for 2 seconds, the frequency of the charger can be changed and
the noise can be reduced.
Also, on that occasion, the operation indicator light will flash orange 2 times.
■ Important points of the wireless charger
●If the electronic key cannot be detected within the vehicle interior, charging
cannot be done. When the door is opened and closed, charging may be
temporarily suspended.
● When charging, the wireless charging device and portable device will get
warmer, however this is not a malfunction.
When a portable device gets warm while charging, charging may stop due
to the protection function on the portable device side. In this case, when the
temperature of the portable device drops significantly, charge again.
■ Operation sounds
When the power supply is turned on, while searching for the portable device a
sound will be produced, however this is not a malfunction.

Maintenance and care
Pull the wiper rubber out past
the stopper on the wiper blade,
and then continue to pull until it
is completely removed.
Lightly grasp between the claws of
the wiper blade to allow the wiper
rubber to lift up, making it easier to
remove.
Remove the 2 metal plates from
the old wiper rubber and install
them to the replacement wiper
rubber.
Insert the wiper rubber starting from the claw at the center of the
wiper blade. Pass the wiper rubber through the 3 claws so that it
sticks out from the stopper, and then pass the wiper rubber through
the final remaining claw.
Applying a small amount of washer fluid to the wiper rubber can make it
easier to insert the claws into the grooves.

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 pressure
label (tire and load information label). (If your vehicle has tires of a dif-
ferent size than the size indicated on the vehicle placard or tire inflation
pressure label [tire and load information 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-ti re pressure warning system) that
illuminates a low tire pre ssure telltale (tire pressure warning light) when
one or more of your tires is significantly under-inflated. Accordingly,
when the low tire pressure telltale (tire pressure warning light) 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 effi ciency and tire tread life, 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 ti re maintenance, and it is the driver’s responsibility 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 indicator to indicate when the system is not
operating properly. The TPMS (tire pressure warning system) malfunc-
tion indicator is combined with the lo w tire pressure telltale (tire pressure
warning light). When the system detects a malfunction, the telltale will
flash for approximately one minute and then remain continuously illumi-
nated. This sequence will continue upon subsequent vehicle start-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 tire 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 warning
system) from functioning properly. Always check the TPMS (tire pres-
sure warning system) malfunction te lltale 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.
