spare wheel TOYOTA MIRAI 2020 Owners Manual (in English)

2385-5. Using the driving support systems
MIRAI_OM_USA_OM62073U
LDA (Lane Depar ture Al ert with steering
control)
When driving on highways and freeways with white (yellow) lane
lines, this function alerts the driver when the vehicle might d epart from
its lane or course
* and provides assistance by operating the steering
wheel to keep the vehicle in its lane or course
*.
The LDA system recognizes white
(yellow) lane lines or a course
*
using the front camera. Addition-
ally, it detects preceding vehicles
using the front camera and radar.
*: Boundary between asphalt and the side of the road, such as grass, soil,
or a curb
Summary of functions
WARNING
■ Before using LDA system
● Do not rely solely upon the LDA system. The LDA system does not auto-
matically drive the vehicle or reduce the amount of attention that must be
paid to the area in front of the vehicle. The driver must always assume full
responsibility for driving safely by paying careful attention to the surround-
ing conditions and operating the steering wheel to correct the path of the
vehicle. Also, the driver must take adequate breaks when fatigu ed, such
as from driving for a long period of time.
● Failure to perform appropriate driving operations and pay caref ul attention
may lead to an accident, resulting in death or serious injury.
● When not using the LDA system, use the LDA switch to turn the system
off.
■ Situations unsuitable for LDA system
In the following situations, use the LDA switch to turn the sys tem off. Failure
to do so may lead to an accident, resulting in death or serious injury.
● Vehicle is driven on a road surface which is slippery due to rainy weather,
fallen snow, freezing, etc.
● Vehicle is driven on a snow-covered road.
● White (yellow) lines are difficult to see due to rain, snow, fo g, dust, etc.
● A spare tire, tire chains, etc. are equipped.

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 p ressure
label (tire and load information label). (If your vehicle has t ires of a dif-
ferent size than the size indica ted on the vehicle placard or tire 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 handl ing and stopping ability.
Please note that the TPMS (tire pressure warning system) is not a sub-
stitute for proper tire maintena nce, 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 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 mi nute 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 al ternate 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 sys tem) to
continue to function properly.

MIRAI_OM_USA_OM62073U
If you have a flat tire
Your vehicle is not equipped with a spare tire, but instead is
equipped with an emergency tire puncture repair kit.
A puncture caused by a nail or screw passing through the tire
tread can be repaired temporarily using the emergency tire
puncture repair kit. (The kit contains a bottle of sealant. The
sealant can be used only once to temporarily repair one tire
without removing the nail o r screw from the tire.)
After temporarily repairing the tire with the repair kit, have the
tire repaired or replace d by your Toyota dealer.
WARNING
■If you have a flat tire
Do not continue driving with a flat tire.
Driving, even a short distance, with a flat tire can damage the tire, the
wheel, and other parts beyond rep air, which could result in an accident.
