WARNING
nReplacing 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.
n 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.

ItemsCheck points
Doors• Do the doors operate smoothly?
Engine hood• Does the engine hood lock systemwork properly?
Fluid leaks
• There should not be any signs offluid leakage after the vehicle has
been parked.
Tires
• Is the tire inflation pressure cor-rect?
• The tires should not be dam-
aged or excessively worn.
• Have the tires been rotated according to the maintenance
schedule?
• The wheel nuts should not be loose.
Windshield wipers/rear window
wiper
• The wiper blades should not show
any signs of cracking, splitting,
wear, contamination or deforma-
tion.
• The wiper blades should clear the

Maintenance and care
Scion iM_U (12J49U)
Your vehicle is equipped with a tire pressure warning system that uses
tire pressure warning valves and tr ansmitters to detect low tire infla-
tion pressure before serious problems arise.
If the tire pressure drops below a predetermined level, the driver is
warned by a warning light. ( P. 263)
uInstalling tire pressure warning valves and transmitters
When replacing tires or wheels, tire pressure warning valves and
transmitters must also be installed.
When new tire pressure warning valves and transmitters are
installed, new ID codes must be registered in the tire pressure
warning computer and the tire pr essure warning system must be
initialized. Have tire pressure warning valves and transmitter ID
codes registered by your Scion dealer. ( P. 223)
uInitializing the tire pressure warning system
nThe tire pressure warning system must be initialized in the fol-
lowing circumstances:
l When rotating front and rear tires which have different tire infla-
tion pressures.
l When changing the tire size.
l When the tire inflation pressure is changed such as when chang-
ing traveling speed or load weight.
When the tire pressure warning system is initialized, the current tire
inflation pressure is set as the benchmark pressure.

How to initialize the tire pressure warning system
Park the vehicle in a safe place and turn the engine switch off.
Initialization cannot be performed while the vehicle is moving.
Adjust the tire inflation pressure to the specified cold tire inflation
pressure level. ( P. 301)
Make sure to adjust the tire pressu re to the specified cold tire infla-
tion pressure level. The tire pressure warning system will operate
based on this pressure level.
Turn the engine switch to the “ON” position.
Open the glove box. Press
and hold the tire pressure
warning reset switch until the
tire pressure warning light
blinks slowly 3 times.
Wait for a few minutes with the eng ine switch in the “ON” position
and then turn the engine switch to the “ACC” or “LOCK” position.
