Checking fluid level
The brake fluid level should be
between the “MAX” and “MIN”
lines on the reservoir.
■Adding fluid
Make sure to check the fluid ty
pe and prepare the necessary ite m.
■Brake fluid can absorb moisture from the air
Excess moisture in the brake fluid can cause a dangerous loss o f braking effi-
ciency. Use only newly opened brake fluid.

Maintenance and care
SEQUOIA_OM_USA_OM0C035U
Rotate the tires in the order
shown.
To equalize tire wear and extend
tire life, Toyota recommends that
tire rotation is carried out at the
same interval as tire inspection.
Do not fail to initialize the tire
pressure warning system after
tire rotation.
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.
● The tire pressure detected by th e tire pressure warning system can
be displayed on the mul ti-information display.
● If the tire pressure drops below
a predetermined level, the
driver is warned by a screen
display and a warning light.
The illustration used is
intended as an example, and
may differ from the image that
is actually displayed on the
multi-informat ion display.
◆Installing tire pressure warn ing 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.

◆Initializing the tire pressure warning system
■The tire pressure warning system must be initialized in the fol-
lowing circumstances:
● When rotating the tires.
● When the tire inflation pressure is changed such as when chang-
ing tire size. (When there are multiple specified pressures)
● After registeri ng the ID codes. ( P. 429)
When the tire pressure warning sy stem 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 s afe place and turn the engine switch off.
Initialization cannot be perfo rmed while the vehicle is moving.
Adjust the tire inflation pressure to the specified cold tire i nflation
pressure level. ( P. 529)
Make sure to adjust the tire pre ssure to the specified cold tire infla-
tion pressure level. The tire pressure warning system will oper ate
based on this pr essure level.
Turn the engine switch to ON.
Push and hold the tire pres-
sure warning reset switch
until the tire pressure warn-
ing light blinks 3 times.
A message is displayed on the
multi-information display. Also,
“- -” is displayed for inflation
pressure of each tire on the
multi-information display while
the tire pressure warning sys-
tem determines the position.

SEQUOIA_OM_USA_OM0C035U
Drive straight (with occasional left and right turns) at approxi-
mately 25 mph (40 km/h) or more for approximately 10 to 30 min-
utes.
Initialization is complete when the position of each tire is determined
and the inflation pressure of ea ch tire is displayed on the multi-infor-
mation display.
Initialization may take longer than approximately 30 minutes in cer-
tain situations, such as when the vehicle is stopped for a long time at
traffic lights, etc. ( P. 433)
◆Registering ID codes
Every tire pressure warning valve and transmitter has a unique ID
code. When replacing a tire pressure warning valve and transmit ter,
it is necessary to register the ID codes.
To register the ID codes, perf orm the following procedure:
Press the tire pressure warn-
ing reset switch 3 times until
the tire pressure warning
light blinks slowly 3 times.
Then a message will be dis-
played on multi-information
display.
When registration is being per-
formed, the tire pressure warn-
ing light will blink for
approximately 1 minute then
illuminate and “- -” will be dis-
played for the inflation pres-
sure of each tire on the multi-
information display.

Drive straight (with occasional left and right turns) at approxi-
mately 25 mph (40 km/h) or more for approximately 10 to 30 min-
utes.
Registration is complete when the tire pressure warning light
turns off and the inflation pressure of each tire is displayed on the
multi-information display.
Registration may take longer t han approximately 30 minutes in
certain situations, such as when the vehicle is stopped for a long
time at traffic lights, etc. (
P. 433)
After registering the ID codes, make sure to initialize the tir e
pressure warning system. (
P. 4 2 8 )
■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 t o
expose the fabric, and bulges indicating internal damage
●A tire goes flat repeatedly or c annot be properly repaired due to the size
or location of a cut or other damage
If you are not sure, consult with your Toyota dealer.
■When replacing the tires and wheels
If the ID code of the tire press ure warning valve and transmitt er is not reg-
istered, the tire pressure warni ng system will not work properly. A f t e r d r i v -
ing for about 20 minutes, the tire pressure warning light blink s for 1
minute and stays on to indi cate 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 u sed, or damage is not obvious.
■Routine tire inflation pressure checks
The tire pressure warning system does not replace routine tire inflation
pressure checks. Make sure to chec k tire inflation pressure as part of
your routine of daily vehicle checks.
