situations:
● A washer does not work.
● “Windshield Washer Fluid Low”
is displayed on the multi-infor-
mation display.
WARNING
■ When adding washer fluid
Do not add washer fluid when the engine is hot or running as washer fluid
contains alcohol and may catch fire if spilled on the engine, etc.
NOTICE
■ Do not use any fluid other than washer fluid
Do not use soapy water or engine antifreeze instead of washer fluid.
Doing so may cause streaking on the vehicle’s painted surfaces, as well as

Tires
Replace or rotate tires in accordance with maintenance sched-
ules and treadwear.
Checking tires
Check if the treadwear indicators are showing on the tires. Also check
the tires for uneven wear, such as excessive wear on one side of the
tread.
Check the spare tire condition and pressure if not rotated.

Tire pressure warning system
Your vehicle is equipped with a tire pressure warning system that uses
tire pressure warning valve and transmitters to detect low tire inflation
pressure before serious problems arise.
● The tire pressure detected by
the tire pressure warning sys-
tem can be displayed on the
multi-information display.
● If the tire pressure drops below
a predetermined level, the
driver is warned by a screen
display and a warning light.
(P. 459)

◆ Installing tire pressure warning valve and transmitters
When replacing the tires or wheels, the tire pressure warning valve
and transmitters must be installed to the wheels which will be
installed to the vehicle.
When new tire pressure warning valve 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. (P. 417)
◆ Initializing the tire pressure warning system
■ The tire pressure warning system must be initialized in the fol-
lowing circumstances:
● When the tire inflation pressure is changed such as when chang-
ing traveling speed or load weight.
● When the tire inflation pressure is changed such as when the tire
size is changed.
● When rotating the tires.
● After performing the transmitter ID code registration procedure.
(P. 417)
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.
1
The initialization procedure cannot be started while the vehicle is
moving.
2
Adjust the tire inflation pressure to the specified cold tire inflation
pressure level. (P. 506)
Make sure to adjust the tire pressure to the specified cold tire infla-
tion pressure level. The tire pressure warning system will operate
based on this pressure level.
3
Start the engine. (P. 186)
4
Select
on the multi-information display using the meter con-
trol switches on the steering wheel. (P. 100)

Select
“Set Pressure” then
press and hold
until
the tire pressure warning
light blinks 3 times.
Then a message will be dis-
played on the multi-information
display.
“---” will be displayed on the
multi-information display for
the inflation pressure of each
tire while initialization is being
performed.
Drive straight (with occasional left and right turns) at approxi-
8
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 each tire is displayed on the multi-infor-
mation display.
Initialization may take longer than approximately 1 hour in certain
situations, such as when the vehicle is stopped for a long time at
traffic lights, etc. (P. 422)
◆ Registering ID codes
6
Every tire pressure warning valve and transmitter has a unique ID
code. When replacing a tire pressure warning valve and transmitter,
it is necessary to register the ID codes.
The ID codes can be registered on
of the multi-information dis-
play.
