2018 TOYOTA AVENSIS warning light

4707-3. Do-it-yourself maintenance
AVENSIS_OM_OM20C79E_(EE)
Your vehicle is equipped with a tire pressure warning system that uses
tire pressure warning valves and transmitters 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. 533)
◆Installing 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 pressure warning system must be
initialized. Have tire pressure warning valve and transmitter ID
codes registered by any authorized Toyota retailer or Toyota autho-
rized repairer, or any reliable repairer. (P. 472)
◆Initializing the tire pressure warning system
■The tire pressure warning system must be initialized in the fol-
lowing circumstances:
●When rotating front and rear tires which have different tire infla-
tion pressures
●When changing the tire size
●When the tire inflation pressure is changed such as when chang-
ing traveling speed
●When changing between two registered wheel sets
When the tire pressure warning system is initialized, the current tire
inflation pressure is set as the benchmark pressure.

Maintenance and care
■How to initialize the tire pressure warning system
Park the vehicle in a safe place and turn the engine switch to the
“LOCK” position (vehicles without smart entry & start system) or
off (vehicles with smart entry & start system).
Initialization cannot be performed while the vehicle is moving.
Adjust the tire inflation pressure to the specified cold tire inflation
pressure level. (P. 623)
Make sure to adjust the tire pressure to the specified cold tire inflation
pressure level. The tire pressure warning system will operate based on
this pressure level.
Turn the engine switch to the “ON” position (vehicles without
smart entry & start system) or IGNITION ON mode (vehicles with
smart entry & start system).
Vehicles with monochrome display
Press the “DISP” switch until the settings screen appears.
(P. 108)
Press and hold the “DISP” switch to enter the adjustment mode.
Press the “DISP” switch until the menu of tire pressure warning
system appears.
Press and hold the “DISP” switch to display the menu.
Press and hold the “DISP”
switch while the cursor is on
“SET TYRE PRESSURE”.
Press and hold the “DISP”
switch while the cursor is on
“SET” to initialize the system.
If initialization is completed,
the tire pressure warning
light will blink 3 times.

Maintenance and care
■When to replace your vehicle’s tires
Tires should be replaced if:
●The treadwear indicators are showing on a tire.
●You have tire damage such as cuts, splits, cracks deep enough to expose
the fabric or 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, consult with any authorized Toyota retailer or Toyota
authorized repairer, or any reliable repairer.
■Replacing tires and wheels (vehicles with the tire pressure warning sys-
tem)
If the ID code of the tire pressure warning valve and transmitter is not regis-
tered, the tire pressure warning system will not work properly. After driving for
about 10 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 (vehicles with the tire pressure
warning system)
The tire pressure warning system does not replace routine tire inflation pres-
sure checks. Make sure to check tire inflation pressure as part of your routine
of daily vehicle checks.
■If the tread on snow tires wears down below 4 mm (0.16 in.)
The effectiveness of the tires as snow tires is lost.

Maintenance and care
■Warning performance of the tire pressure warning system (if equipped)
The warning of the tire pressure warning system will change in accordance
with the conditions under which it was initialized. For this reason, the system
may give a warning even if the tire pressure does not reach a low enough
level, or if the pressure is higher than the pressure that was adjusted to when
the system was initialized.
■When initialization of the tire pressure warning system has failed (if
equipped)
Initialization can be completed in a few minutes. However, in the following
cases, the settings have not been recorded and the system will not operate
properly. If repeated attempts to record tire inflation pressure settings are
unsuccessful, have the vehicle inspected by any authorized Toyota retailer or
Toyota authorized repairer, or any reliable repairer.
●When operating the initialization of the system, the tire pressure warning
light does not blink 3 times.
●After driving for a certain period of time since the initialization has been
completed, the warning light comes on after blinking for 1 minute.
■Low profile tires (225/45R18 tires)
Generally, low profile tires will wear more rapidly and tire grip performance
will be reduced on snowy and/or icy roads when compared to standard tires.
Be sure to use snow tires or tire chains on snowy and/or icy roads and drive
carefully at a speed appropriate for road and weather conditions.

WARNING
■When inspecting or replacing tires
Observe the following precautions to prevent accidents.
Failure to do so may cause damage to par ts of the drive train, as well as
dangerous handling characteristics, which may lead to an accident resulting
in death or serious injury.
● Do not mix tires of different makes, models or tread patterns.
Also, do not mix tires of remarkably different treadwear.
● Do not use tire sizes other than those recommended by Toyota.
● Do not mix differently constructed tires (radial, bias-belted or bias-ply
tires).
● Do not mix summer, all season and snow tires.
● Do not use tires that have been used on another vehicle.
Do not use tires if you do not know how they were used previously.
● Vehicles with a compact spare tire: Do not tow if your vehicle has a com-
pact spare tire installed.
■ When initializing the tire pressure warning system (if equipped)
Do not initialize tire inflation pressure without first adjusting the tire inflation
pressure to the specified level. Otherwise, the tire pressure warning light
may not come on even if the tire inflation pressure is low, or it may come on
when the tire inflation pressure is actually normal.
NOTICE
■ Repairing or replacing tires, wheels, tire pressure warning valves,
transmitters and tire valve caps (vehicles with the tire pressure warn-
ing system)
● When removing or fitting the wheels, tires or the tire pressure warning
valves and transmitters, contact any authorized Toyota retailer or Toyota
authorized repairer, or any reliable repairer as the tire pressure warning
valves and transmitters may be damaged if not handled correctly.
● Make sure to install the tire valve caps. If the tire valve caps are not
installed, water could enter the tire pressure warning valves and the tire
pressure warning valves may seize.
● When replacing tire valve caps, do not use tire valve caps other than those
specified. The cap may become stuck.

■After a fuse is replaced
● If the lights do not turn on even after the fuse has been replaced, a bulb may
need replacement. ( P. 501)
● If the replaced fuse blows again, have the vehicle inspected by any autho-
rized Toyota retailer or Toyota authorized repairer, or any reliable repairer.
■ If there is an overload in the circuits
The fuses are designed to blow, protecting the wiring harness from damage.
WARNING
■ To prevent system breakdowns and vehicle fire
Observe the following precautions.
Failing to do so may cause damage to the vehicle, and possibly a fire or
injury.
● Never use a fuse of a higher amperage rating than indicated, or use any
other object in place of a fuse.
● Always use a genuine Toyota fuse or equivalent.
Never replace a fuse with a wire, even as a temporary fix.
● Do not modify the fuse or the fuse box.
NOTICE
■Before replacing fuses
Have the cause of electrical overload determined and repaired by any
authorized Toyota retailer or Toyota authorized repairer, or any reliable
repairer, as soon as possible.
