It is normal for the brake fluid level to go down slightly as t he brake pads
wear or when the fluid level in the accumulator is high.
If the reservoir needs frequent refilling, it may indicate a se rious problem.

Your vehicle is equipped with a tire pressure warning system that uses
tire pressure warning valves and transmitters to detect low tir e infla-
tion pressure before serious problems arise.
If the tire pressure drops below a predetermined level, the dri ver is
warned by a warning light. ( P. 686)
◆Installing tire pressure warning valves and transmitters
When replacing tires or wheels, tire pressure warning valves an d
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 I D
codes registered by any authorized Toyota retailer or Toyota au tho-
rized repairer, or any reliable repairer. ( P. 620)
◆Initializing the tire pressure warning system
When the tire size is changed, the tire pressure warning system
must be initialized.
When the tire pressure warning system is initialized, the curre nt 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 power switch off.
Initialization cannot be performed while the vehicle is moving.
Adjust the tire inflation pressure to the specified cold tire i nflation
pressure level. ( P. 776)
Make sure to adjust the tire pressure to the specified cold tire inflation
pressure level. The tire pressure warning system will operate b ased on
this pressure level.
Turn the power switch to ON mode.
Press “ ” or “” of the meter control switch to select .
( P. 170)
Press “ ” or “” of the meter control switch to select the “Vehicle
Settings” and then press to display the menu.
Press “ ” or “” of the meter
control switch to select
and then press
.
Press “ ” or “” of the meter control switch to select “SET” and
then press and hold .
When initialization completes, a message is displayed on the
multi-information display and the tire pressure warning light w ill
blink 3 times.

◆Registering ID codes
The tire pressure warning valve and transmitter is equipped wit h a
unique ID code. When replacing a tire pressure warning valve an d
transmitter, it is necessary to register the ID code. Have the ID code
registered by any authorized Toyota retailer or Toyota authoriz ed
repairer, or any reliable repairer.
■ 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, 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, consult with any authorized Toyota retaile r or Toyota
authorized repairer, or any reliable repairer.
■ Replacing tires and wheels
If the ID code of the tire pressure warning valve and transmitt er 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 techni cian even if it
has seldom or never been used, or damage is not obvious.
■ Routine tire inflation pressure check
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.

■ The initialization operation
● Make sure to carry out initialization after adjusting the tire inflation pressure.
Also, make sure the tires are cold before carrying out initiali zation or tire
inflation pressure adjustment.
● If you have accidentally turned the power switch off during initialization, it is
not necessary to press the reset switch again as initialization will restart
automatically when the power switch has been turned to ON mode for the
next time.
● If you accidentally press the reset switch when initialization is not necessary,
adjust the tire inflation pressure to the specified level when the tires are
cold, and conduct initialization again.
■ Warning performance of the tire pressure warning system
The warning of the tire pressure warning system will change in accordance
with the conditions under which it was initialized. For this re ason, the system
may give a warning even if the tire pressure does not reach a l ow 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
Initialization can be completed in a few minutes. However, in t he following
cases, the settings have not been recorded and the system will not operate
properly. If repeated attempts to record tire inflation pressur e settings are
unsuccessful, have the vehicle inspected by any authorized Toyo ta retailer or
Toyota authorized repairer, or any reliable repairer as soon as possible.
● When operating the initialization of the system, the tire pressure warning
light does not flash 3 times and the setting message does not a ppear on the
multi-information display.
● After driving for a certain period of time since the initialization has been
completed, the warning light comes on after blinking for 1 minu te.
■ Registering ID codes
The ID codes of the tire pressure warning valve and transmitter s for two sets
of wheels can be registered.
It is not necessary to register the ID codes when replacing nor mal tires with
snow tires, if the ID codes for the wheels of both normal tires and snow tires
are registered beforehand.
For information about changing ID codes, ask any authorized Toy ota retailer
or Toyota authorized repairer, or any reliable repairer.
