■
Brake fluid can absorb moisture from the air
Excess moisture in the fluid can cause a dangerous loss of braking effi-
ciency. Use only newly opened brake fluid.
CAUTION
■When filling the reservoir
Take care because brake fluid can harm your hands or eyes and damage
painted surfaces.
If fluid gets in your eyes, flush your eyes with clean water immediately.
If you still experience discomfort, see a doctor.
NOTICE
■If the fluid level is low or high
It is normal for the brake fluid level to go down slightly as the brake pads
wear or when the fluid level in the accumulator is high.
If the reservoir needs frequent refilling, it may indicate a serious pro\
blem.

● Is the fuel empty?
If it is, fill the fuel tank immediately.
● Is the fuel tank cap loose?
If it is, tighten it securely.
The malfunction indicator lamp will go off after taking several driving trips. If
the malfunction indicator lamp does not go off even after several trips, con-
tact your Toyota dealer as soon as possible.
■ If the low speed four-wheel drive in dicator light or the center differen-
tial lock indicator light blinks
Take the specified steps. ( P. 206)
If the brake system warning light or the malfunction indicator light also
comes on, or the low speed four-wheel drive indicator light or the center dif-
ferential lock indicator light continues to blink after taking the specified steps,
there may be a malfunction in the engine, the brake system or the four-
wheel drive system. In this case, you may not be able to transfer between
“H4” and “L4” modes, and the center differential lock may not be able to be
locked or unlocked. Have the vehicle inspected by your Toyota dealer imme-
diately.

● If luggage is placed on the front passenger seat, the front passenger
detection sensor may cause the warning light to flash, even if a passen-
ger is not sitting in the seat.
● If a cushion is placed on the seat, the sensor may not detect a passen-
ger, and the warning light may not operate properly.
