snow chains TOYOTA iQ EV 2013 Owners Manual (in English)

2125-5. Using the driving support systems
CAUTION
■The ABS does not operate effectively when
● The limits of tire gripping performance have been exceeded.
● The vehicle hydroplanes while driving at high speed on wet or slick roads.
■ Stopping distance when the ABS is operating may exceed that of nor-
mal conditions
The ABS is not designed to shorten the vehicle’s stopping distance. Always
maintain a safe distance from the vehicle in front of you, especially in the
following situations:
● When driving on dirt, gravel or snow-covered roads
● When driving with tire chains
● When driving over bumps in the road
● When driving over roads with potholes or uneven surfaces
■ TRAC may not operat e effectively when
Directional control and power may not be achievable while driving on slip-
pery road surfaces, even if the TRAC system is operating.
Do not drive the vehicle in conditions where stability and power may be lost.
■ When the VSC is activated
The slip indicator flashes. Always drive carefully. Reckless driving may
cause an accident. Exercise particular care when the indicator flashes.
■ Replacing tires
Make sure that all tires are of the specified size, brand, tread pattern and
total load capacity. In addition, make sure that the tires are inflated to the
recommended tire inflation pressure level.
The ABS, TRAC and VSC systems will not function correctly if different tires
are installed on the vehicle.
Contact your Scion dealer for further information when replacing tires or
wheels.
■ Handling of tires and the suspension
Using tires with any kind of problem or modifying the suspension will affect
the driving assist systems, and may cause a system to malfunction.

Winter driving tips
●Use fluids that are appropriate to the prevailing outside tempera-
tures.
• Inverter coolant
• Washer fluid
● Have a service technician inspec t the condition of the 12-volt bat-
tery.
● Have the vehicle fitted with four snow tires or purchase a set of tire
chains for the front tires.
Ensure that all tires are the same size and brand, and that chains match
the size of the tires.
Perform the following accordin g 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, ve hicle’s roof, chassis, around the
tires or on the brakes.
● Remove any snow or mud from the bottom of your shoes before
getting in the vehicle.
Carry out the necessary preparations and inspections before
driving the vehicle in winter. Always drive the vehicle in a man-
ner appropriate to the prevailing weather conditions.

■Tire chain installation
Observe the following precautions when installing and removing chains:
●Install and remove tire chains in a safe location.
● Install tire chains on the front tires only. Do not install tire chains on the rear
tires.
● Install tire chains on front tires as tightly as possible. Retighten chains after
driving 1/4  1/2 mile (0.5  1.0 km).
● Install tire chains following the instructions provided with the tire chains.
● If wheel ornaments are used, they will be scratched by the chain band, so
remove the ornaments before putting on the chains. ( P. 271)
■ Cooling fan
Snow may enter from the opening of the front bumper and so forth, and ma\
y
adhere to the cooling fan. Press and check whether the cooling fan is
operating. If the cooling fan does not operate, it is possible that the cooling
fan is frozen. (However, when outside temperature is below 14°F [-10°C], the
cooling fan may not operate)
If the cooling fan is frozen, remove any snow and ice from the cooling fan
area.
CAUTION
■ Driving with snow tires
Observe the following precautions to reduce the risk of accidents.
Failure to do so may result in a loss of vehicle control and cause death or
serious injury.
● Use tires of the specified size.
● Maintain the recommended level of air pressure.
● Do not drive in excess of 75 mph (120 km/h), regardless of the type of
snow tires being used.
● Use snow tires on all, not just some wheels.
● Do not mix tires of different marks, models, tread patterns or treadwear.

2185-6. Driving tips
CAUTION
■Driving with tire chains
Observe the following precautions to reduce the risk of accidents.
Failure to do so may result in the vehicle being unable to be driven safely,
and may cause death or serious injury.
● Do not drive in excess of the speed limit specified for the tire chains being
used, or 30 mph (50 km/h), whichever is lower.
● Avoid driving on bumpy road surfaces or over potholes.
● Avoid sudden acceleration, abrupt steering, sudden braking and shifting
operations that cause sudden regenerative braking.
● Slow down sufficiently before entering a curve to ensure that vehicle con-
trol is maintained.
■ When removing snow and ice from cooling fan
Please turn the power switch off. Also, if you are in the middle of charging
the vehicle, please stop charging. With the power switch in ACCESSORY or
ON mode, or charging, there is a possibility of the cooling fan suddenly
beginning to turn and the danger of hands, clothes, etc. being caught in the
fan, resulting in serious injury.
NOTICE
■Repairing or replacing snow tires
Request repairs or replacement of snow tires from Scion dealers or legiti-
mate tire retailers.
This is because the removal and attachment of snow tires affects the opera-
tion of the tire pressure warning valves and transmitters.
■ Fitting tire chains
The tire pressure warning valves and transmitters may not function correctly
when tire chains are fitted.
■ When the cooling fan freezes
Do not run the cooling for a long time in the frozen state.
The heating effect not only becomes weak, but there is a possibility of dam-
aging the cooling fan.

3408-2. Steps to take in an emergency
■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 temper-
ature. In this case, adjusting the tire inflation pressure will turn off the
warning light (after a few minutes).
■If the tire pressure warning system is not functioning
The tire pressure warning system will be disabled in the following condi-
tions:
(When the condition be comes normal, the system will work properly.)
●If tires not equipped with tire pressure warning valves and transmitters
are used.
●If the ID code on the tire pressure warning valves and transmitters is not
registered in the tire pressure warning computer.
●If the tire inflation pressure is 73 psi (500 kPa, 5.1 kgf/cm2 or bar) or
higher.
The tire pressure warning system may be disabled in the following conditions:
(When the condition becomes normal, the system will work properly.)
●
If electronic devices or facilities using similar radio wave frequencies are
nearby.
●If a radio set at similar frequency is in use in the vehicle.
●If a window tint that affects the radio wave signals is installed.
●If there is a lot of snow or ice on the vehicle, particular around the
wheels or wheel housings.
●If non-genuine Scion wheels are used. (Even if you use Scion wheels,
the tire pressure warning system may not work properly with some types
of tires.)
●If tire chains are used.
●If emergency tire puncture repair kit is used.
■If the tire pressure warning light frequently comes on after blinking
for 1 minute
If the tire pressure warning light frequently comes on after blinking for 1
minute when the power switch is turn ed to ON mode, have it checked by
your Scion dealer.
■Warning buzzer
In some cases, the buzzer may not be heard because of noisy place or
an audio sound.
