To prevent burning yourself, do not check the washer fluid level when
the engine is hot.CAUTION
!
NOTICE
After checking the washer fluid
level, make sure the dipstick is se-
curely reinserted. If it is loose, fluid may leak from the reservoir.
Do not check the washer fluid lev-el or add washer fluid when the en-gine is running or when it is hot.If the fluid is spilled over the hot
engine, a fire could result.
If you have added washer fluid un-til it is close to the top of the open-
ing for adding fluid, do not pullout the dipstick. Otherwise, thefluid will overflow.
Do not use engine antifreeze or
any other substitute because itmay damage your vehicle's paint.
The headlights have the beam angle
gauges to check:
1. Vertical movement
2. Horizontal movement
To obtain correct gauge readings, do
these before you check the headlightaims. Make sure the body around the head- light is not deformed.
Park the vehicle on a level spot.
Fill up the fuel tank.
Bounce the vehicle several times.
A passenger should sit on the driver's
seat while checking the headlight aims.Vertical movement gauges: The bubble
on the gauge should be within six marks
from center on both sides.
Checking headlight aims

186
Horizontal movement gauges: The red
mark on the gauge should be within two
marks from the center on both sides.
If a gauge reading is not within the accept-
able range, have the aiming adjusted by
your Toyota dealer.The following illustrations show how to
gain access to the bulbs. When replacing
a bulb, make sure the ignition switch and
light switch are off. Use bulbs with the wattage ratings given in the table.
Halogen bulbs have pressurized
gas inside and require special
handling. They can burst or shatter
if scratched or dropped. Hold a bulb
