3. Instrument cluster
■The meters and display illuminate when
The power switch is in ON mode.
■ Adjusting the instrument cluster brightness (→P. 182)
● The brightness levels that can be selected differ depending on whether the
tail lights are on and surrounding brightness levels, as shown in the table
below.
*: 22 levels of the brightness are displayed on the setting screen. However,
the brightness setting will be the brightest when other than 1st level (the
darkest) is selected. If other than 1st or 22nd level is selected, when the
tail lights are turned on in a dark place, the instrument cluster brightness
setting will be the selected level.
● If the taillights are illuminated in a dark environment, the instrument cluster
light dims. However, when the brightness of the instrument cluster is set to
minimum or maximum (1st or 22nd level of the instrument cluster bright-
ness), even if the taillights are illuminated, the instrument cluster light will
not dim.
■ When disconnecting and reconnect ing 12-volt battery terminals
The settings of the clock will be reset.
■ Calendar settings
●Until the calendar settings are set, the check screen is displayed every time
the power switch is turned to ON mode.
● After the calendar information is set, it can be changed in the “Meter Cus-
tomize” settings. ( →P. 233)

If calendar recording is interrupted due to
replacement of the 12-volt battery or 12-
volt battery discharge, etc., when the
power switch is turned to ON mode after
maintenance, the calendar settings check
screen is automatically displayed on the
multi-information display.
● If date information is not set, the electric-
ity and fuel consumption record cannot
be stored correctly. When the calendar

make sure to always set the settings.

7-3. Do-it-yourself maintenance
■After a fuse is replaced
●If the lights do not turn on even after the fuse has been replaced, a bulb may
need replacement. ( →P. 635)
● If the replaced fuse blows again, have the vehicle inspected by your Toyota
dealer.
■ If there is an overload in a circuit
The fuses are designed to blow, protecting the wiring harness from damage.
■ When replacing light bulbs
Toyota recommends that you use genuine Toyota products designed for this
vehicle. Because certain bulbs are connected to circuits designed to prevent
overload, nongenuine parts or parts not designed for this vehicle may be
unusable.
WARNING
■To prevent system breakdowns and vehicle fire
Observe the following precautions.
Failure to do so may cause damage to the vehicle, and possibly a fire or
injury.
● Never use a fuse of a higher amperage rating than that indicated, or use\
any other object in place of a fuse.
● Always use a genuine Toyota fuse or equivalent.
Never replace a fuse with a wire, even as a temporary fix.
● Do not modify the fuses or fuse boxes.
NOTICE
■Before replacing fuses
Have the cause of electrical overload determined and repaired by your
Toyota dealer as soon as possible.

When trouble arises
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 hand ling 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 w ill continue upon subsequ ent 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.

When trouble arises
■The valve of a tire that has been repaired
After a tire is repaired with the emergency tire puncture repair kit, the
valve should be replaced.
■After a tire is repaired with the emergency tire puncture repair kit
●The tire pressure warning valve and transmitter should be replaced.
●Even if the tire inflation pressure is at the recommended level, the tire
pressure warning light may come on/flash.
■Note for checking the emergency tire puncture repair kit
Check the sealant expiry date occasionally.
The expiry date is shown on the bottle. Do not use sealant whose expiry
date has already passed. Otherwise, repairs conducted using the emer-
gency tire puncture repair kit may not be performed properly.
■Emergency tire puncture repair kit
●The emergency tire punctu re repair kit is for filling the car tire with air.
●The sealant has a limited life span. The expiry date is marked on the
bottle. The sealant should be replaced before the expiry date. Contact
your Toyota dealer for replacement.
●The sealant stored in the emergency ti re puncture repair kit can be used
only once to temporarily repair a single tire. If the sealant in the bottle
and other parts of the kit have been used and need to be replaced, con-
tact your Toyota dealer.
●The compressor can be used repeatedly.
●The sealant can be used when the outside temperature is from -40°F
(-40°C) to 140°F (60°C).
●The kit is exclusively designed for size and type of tires originally
installed on your vehicle. Do not use it for tires that a different size than
the original ones, or for any other purposes.
●If the sealant gets on your clothes, it may stain.
●If the sealant adheres to a wheel or the surface of the vehicle body, the
stain may not be removable if it is not cleaned at once. Immediately wipe
away the sealant with a wet cloth.
●During operation of the repair kit, a loud operation noise is produced.
This does not indicate a malfunction.
●Do not use to check or to adjust the tire pressure.
