CAUTION
■The ABS does not operate effectively when
● Tires with inadequate gripping ability are used (such as excessively worn
tires on a snow covered road).
● 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 in the following situ-
ations:
● 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 roads with uneven surfaces
■ TRAC may not operate 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 VSC is activated
The slip indicator light flashes. Always drive carefully. Reckless driving may
cause an accident. Exercise particular care when the indicator light flashes.
■ When the TRAC/VSC syst ems are turned off
Be especially careful and drive at a speed appropriate to the road condi-
tions. As these are systems to ensure vehicle stability and driving force, do
not turn the TRAC/VSC systems off unless necessary.

Winter driving tips
Carry out the necessary preparations and inspections before driving
the vehicle in winter. Always drive the vehicle in a manner appropri-
ate to the prevailing weather conditions.
■ Pre-winter preparations
●Use fluids that are appropriate to the prevailing outside tem-
peratures.
• Engine oil
• Engine coolant
• Washer fluid
● Have a service technician inspect the level and specific grav-
ity of battery electrolyte.
● 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.

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 size specified.
● 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.
■ 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 turns and braking, as use of chains may adversely affect
vehicle handling.
● Slow down sufficiently before entering a curve to ensure that vehicle con-
trol is maintained.

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.

Scion_tC_U_(OM21041U)
■When to replace your vehicle’s tires
Tires should be replaced if:
●You have tire damage such as cuts, splits, cracks deep enough to
expose the fabric, and bulges indicating internal damage
●A tire goes flat repeatedly or cannot be properly repaired due to the
size or location of a cut or other damage
If you are not sure, consul t with your Scion dealer.
■Replacing tires and wheels (U.S.A. only)
If the ID code of the tire pressure warning valve and transmitter is not
registered, the tire pressure warning system will not work properly. After
driving for about 20 minutes, the tire pressure warning light blinks for
1 minute and stays on to indicate a system malfunction.
■Tire life
Any tire over 6 years old must be checked by a qualified technician even
if it has seldom or never been used or damage is not obvious.
■Routine tire inflation pressure checks (U.S.A. only)
The tire pressure warning system doe s not replace routine tire inflation
pressure checks. Ma ke sure to check tire infl ation pressure as part of
your routine of daily vehicle checks.
■Low profile tires (P225/45R18 tires)
Generally, low profile tire s will wear more rapidly and tire grip perfor-
mance will be reduced on snowy and/or icy roads when compared to
standard tires. Be sure to use snow ti res or tire chains on snowy and/or
icy roads and drive carefully at a speed appropriate for road and weather
conditions.

■If the tire pressure warning system is not functioning (U.S.A. only)
The system will be disabled in the following conditions:

(When the condition be comes normal, the system will work properly.)
●If tires not equipped with tire pressure warning valves and transmit-
ters 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 condi-
tions: 
(When the condition be comes normal, the system will work properly.)
●If electronic devices or facilities using similar radio wave frequencies
are nearby.
●If a radio set at a 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, particularly 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.

■After completing the tire change (U.S.A. only)
The tire pressure warning
system must be reset. (P. 3 1 1 )
■When using the compact spare tire (U.S.A. only)
As the compact spare tire is not equipped with a tire pressure warning
valve and transmitter, low inflation pressure of the spare tire will not be
indicated by the tire pressure warn ing system. Also, if you replace the
compact spare tire after the tire pressure warning light comes on, the
light remains on.
■If you have a flat front tire on a road covered with snow or ice
Install the compact spare tire on one of the rear wheels of the vehicle.
Perform the following steps and fit tire chains to the front tires:
Replace a rear tire with the compact spare tire.
Replace the flat front tire with t he tire removed from the rear of
the vehicle.
Fit tire chains to the front tires.
