Iridium−tipped spark plugs
Your engine is fitted with iridium−tipped
spark plugs.
NOTICE
Use only iridium−tipped spark plugs.
Do not adjust gaps for engine perfor-
mance or smooth drivability.

Brake system

This brake system has two independent
hydraulic circuits. If either circuit should
fail, the other will still work. However, the
pedal will be harder to press, and your
stopping distance will increase. Also, the
brake system warning light may come on.
CAUTION
Do not drive your vehicle with only a
single brake system. Have
brakes fixed immediately.
BRAKE BOOSTER
The brake booster uses brake fluid pres-
surized by the pump to power−assist the
brakes. If the brake booster fails during
driving, the brake system warning light
comes on and buzzer sound continuously.
In this case, the brakes may not work
properly. If they do not work well, depress
the brake pedal firmly. If the brake system
warning light comes on, immediately stop
your vehicle and contact your Toyota deal-
er.
