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 pres sure 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 illumina tion 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 dete cts a malfunction, the telltale will
flash for approximately one minute and then remain continuously illumi-
nated. This sequence will continue up on 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 installati on 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.

■Stopping the fuel cell system
Shift the shift position to P and press the power switch as you normally do
when stopping the fuel cell system.
■ Replacing the key battery
As the above procedure is a temporary measure, it is recommended that the
electronic key battery be replaced immediately when the battery is depleted.
( P. 353)

MIRAI_OM_USA_OM62004U
Start the fuel cell system and turn the air conditioning system on
to check that the radiator coo ling fans operate and to check for
coolant leaks from th e radiator or hoses.
The fans operate when the air conditioning system is turned on immedi-
ately after a cold start. Confirm that the fans are operating by checking
the fan sound and air flow. If it is difficult to check these, turn the air con-
ditioning system on and off repeatedly.
(The fans may not operate in freezing temperatures.)
If the fans are not operating:
Stop the fuel cell system immediately and contact your Toyota
dealer.
If the fans are operating:
Have the vehicle inspected at the nearest Toyota dealer.
WARNING
■When inspecting under the hood of your vehicle
Observe the following precautions.
Failure to do so may result in serious injury such as burns.
●If steam is seen coming from under the hood, do not open the hood until
the steam has subsided. The motor compartment may be very hot.
● After the fuel cell system has been turned off, check that the “READY”
indicator is off.
When the fuel cell system is operating, the cooling fans may suddenly
operate even if the fuel cell system stops. Do not touch or approach rotat-
ing parts such as the fans, which may lead to fingers or clothing (espe-
cially a tie, a scarf or a muffler) getting caught, resulting in serious injury.
● Do not loosen the coolant reservoir caps or radiator cap, while the fuel cell
system and radiator are hot.
High temperature steam or coolant could spray out.

If the vehicle becomes stuck
Set the parking brake and stop the fuel cell system.
Remove the mud, snow or sand from around the front wheels.
Place wood, stones or some other material under the front wheels
to help provide traction.
Restart the fuel cell system.
Shift the shift position to D or R and release the parking brake.
Then, while exercising caution, depress the accelerator pedal.
■ When it is difficult to free the vehicle
Carry out the following procedures if the tires spin or the vehicle
becomes stuck in mud, dirt or snow:

Press to turn off TRAC.
WARNING
■When attempting to free a stuck vehicle
If you choose to push the vehicle back and forth to free it, make sure the
surrounding area is clear to avoid striking other vehicles, objects or people.
The vehicle may also lunge forward or lunge back suddenly as it becomes
free. Use extreme caution.
■ When shifting the shift position
Be careful not to shift the shift position with the accelerator pedal
depressed.
This may lead to unexpected rapid acceleration of the vehicle that may
cause an accident resulting in death or serious injury.
