1884-2. Driving procedures
WARNING
■When parking
Exhaust gases include harmful carbon monoxide (CO), which is colorless
and odorless. Observe the following precautions.
Failure to do so may cause exhaust gases to enter the vehicle and may
lead to an accident caused by light-headedness, or may lead to death or a
serious health hazard.
●If the vehicle is in a poorly ventilated area or a closed area, such as a
garage, stop the engine.
●Do not leave the vehicle with the engine running for a long time. If such a
situation cannot be avoided, park the vehicle in an open space and ensure
that exhaust fumes do not enter the vehicle interior.
●Do not leave the engine running in an area with snow build-up, or where it
is snowing. If snowbanks build up around the vehicle while the engine is
running, exhaust gases may collect and enter the vehicle.
NOTICE
■To prevent battery discharge
●Do not leave the engine switch in ACCESSORY or IGNITION ON mode
for long periods of time without the engine running.
●If “ACCESSORY” or “IGNITION ON” is displayed on the multi-information
display, the engine switch is not off. Exit the vehicle after turning the
engine switch off.
●Do not stop the engine when the shift lever is in a position other than P. If
the engine is stopped in another shift lever position, the engine switch will
not be turned off but instead be turned to ACCESSORY mode. If the vehi-
cle is left in ACCESSORY mode, battery discharge may occur.
■When starting the engine
●Do not race a cold engine.
●If the engine becomes difficult to start or stalls frequently, have your vehi-
cle checked by your Toyota dealer immediately.
■Symptoms indicating a malfunction with the engine switch
If the engine switch seems to be operating somewhat differently than usual,
such as the switch sticking slightly, there may be a malfunction. Contact
your Toyota dealer immediately.

WARNING
■Caution regarding the use of washer fluid
When it is cold, do not use the washer fluid until the windshield becomes
warm. The fluid may freeze on the windshield and cause low visibility. This
may lead to an accident, resulting in death or serious injury.
NOTICE
■When the windshield is dry
Do not use the wipers, as they may damage the windshield.
■When the washer fluid tank is empty
Damage to the washer fluid pump may be caused if the lever is pulled
toward you and held continually.
■When a nozzle becomes blocked
In this case, contact your Toyota dealer.
Do not try to clear it with a pin or other object. The nozzle will be damaged.

●Use fluids that are appropriate to the prevailing outside tempera-
tures.
• Engine oil
• Engine coolant
• Washer fluid
●Have a service technician inspect the condition of the battery.
●Have the vehicle fitted with four snow tires or purchase a set of tire
chains for the front tires.

*: Tire chains cannot be mounted on vehicles with 18 and 19-inch tires.
Perform the following according to the driving conditions:
●Do not try to forcibly open a window or move a wiper that is frozen.
Pour warm water over the frozen area to melt the ice. Wipe away
the water immediately to prevent it from freezing.
●To ensure proper operation of the climate control system fan,
remove any snow that has accumulated on the air inlet vents in
front of the windshield.
●Check for and remove any excess ice or snow that may have accu-
mulated on the exterior lights, vehicle’s roof, chassis, around the
tires or on the brakes.

●The wireless charger is designed to supply low power electricity (5 W or
less) to a cellular phone, smartphone, or other portable device.
■If a cover or accessory is attached to the portable device
Do not charge a portable device if a cover or accessory which is not Qi com-
patible is attached. Depending on the type of cover and/or accessory
attached, it may not be possible to charge the portable device. If the portable
device is placed on the charging area and does not charge, remove the cover
and/or accessories.
■If interference is heard in AM radio broadcasts while charging
Turn off the wireless charger and check if the noise is reduced. If noise is
reduced, press and hold the power supply switch of the wireless charger for 2
seconds. The frequency of the wireless charger is changed and noise may be
reduced. When the frequency is changed, the operation indicator light will
blink (orange) 2 times.

warm. This is not a malfunction.
If a portable device becomes warm while charging and charging stops due
to the protection function of the portable device, wait until the portable
device cools down and charge it again.
■Sound generated during operation

4407-2. Steps to take in an emergency
■When the tire pressure warning light comes on
Inspect the tires to check if a tire is punctured.
If a tire is punctured: P. 449
If none of the tires are punctured:
Turn the engine switch off then turn it to IGNITION ON mode. Check if the
tire pressure warning light comes on or blinks.
If the tire pressure warning light comes on
After the temperature of the tires has lowered sufficiently, check the
inflation pressure of each tire and adjust them to the specified level.
If the warning light does not turn off even after several minutes have
elapsed, check that the inflation pressure of each tire is at the specified
level and perform initialization. (P. 3 9 6 )
If the warning light does not turn off several minutes after the initialization
has been performed, have the vehicle inspected by your Toyota dealer
immediately.
If the tire pressure warning light blinks for 1 minute then stays on
There may be a malfunction in the tire pressure warning system. Have
the vehicle inspected by your Toyota dealer immediately.
■The tire pressure warning light may come on due to natural causes
The tire pressure warning light may come on due to natural causes such
as natural air leaks and tire inflation pressure changes caused by tem-
perature. In this case, adjusting the tire inflation pressure will turn off the
warning light (after a few minutes).
■When a tire is replaced with a spare tire
The compact spare tire is not equipped with a tire pressure warning valve
and transmitter. If a tire goes flat, the tire pressure warning light will not
turn off even though the flat tire has been replaced with the spare tire.
Replace the spare tire with the repaired tire and adjust the tire inflation
pressure. The tire pressure warning light will go off after a few minutes.
■Conditions that the tire pressure warning system may not function
properly
P. 4 0 0
■Warning buzzer
In some cases, the buzzer may not be heard because of noisy place or an
audio sound.
