Daytime running light (DRL) system (all
models sold in Canada and some mod-
els sold in U.S.A.)
Daytime Running Light (DRL) system can
make it easier for others to see the front
of your vehicle during the day. The DRL
system can be helpful in many different
driving conditions, but they can be espe-
cially helpful in the short periods after
dawn and before sunset.
The DRL system will make your front turn
signal lights come on when:
The ignition is on with the engine run-
ning.
The knob is in the “OFF” position or
position 1.
The parking brake is released.
To turn off the DRL system, twist the knob
to the position 2 or turn the ignition switch
off.
This DRL system can be disabled. For
details, contact your Toyota dealer.
HighLow beams— For high beams, turn
the headlights on and push the lever away
from you (position 1). Pull the lever to-
ward you (position 2) for low beams.
The headlight high beam indicator light
(blue light) on the instrument panel will
tell you that the high beams are on.
Flashing the high beam headlights
(position 3)—Pull the lever all the way
back. The high beam headlights turn off
when you release the lever.
You can flash the high beam headlights
with the knob turned to “OFF”.TURN SIGNALS
To signal a turn, push the headlight/
turn signal lever up or down to position
1.
The key must be in the “ON” position.
The lever automatically returns after you
make a turn, but you may have to return
it by hand after you change lanes.
To signal a lane change, move the lever
up or down to the pressure point (position
2) and hold it.
On some models, the front turn signal
lights are on during daytime running light
system is on. For details, see “Daytime
running light system”.

lights, turn signal lights, and other lights
are all working. Check headlight aim.
Service reminder indicators and warning
buzzers
Check that all service reminder indicators
and warning buzzers function properly.
Steering wheel
Check that it has the specified free play.
Be alert for changes in steering condition,
such as hard steering or strange noise.
Seats
Check that all front seat controls such as
seat adjusters, seatback recliner, etc. op-
erate smoothly and that all latches lock
securely in any position. Check that the
head restraint move up and down smooth-
ly and that the locks hold securely in any
latched position. For foldingdown rear
seatbacks and swingup rear seat cush-
ions, check that the latches lock securely. Seat belts
Check that the seat belt system such as
buckles, retractors and anchors operate
properly and smoothly. Make sure that the
belt webbing is not cut, frayed, worn or
damaged.
Accelerator pedal
Check the pedal for smooth operation and
uneven pedal effort or catching.
Brake pedal
Check the pedal for smooth operation and
that the pedal has the proper clearance.
Check the brake booster function.
Brakes
At a safe place, check that the brakes do
not pull to one side when applied.
Parking brake
Check that the pedal has the proper travel
and that, on a safe incline, your vehicle
is held securely with only the parking
brake applied.
Automatic transmission “Park” mecha-
nism
On a safe incline, check that your vehicle
is held securely with the selector lever in
“P” position and all brakes released.IN THE ENGINE COMPARTMENT
Items listed below should be checked
from time to time, e.g. each time when
refueling.
Washer fluid
Make sure there is sufficient fluid in the
tank. See page 343 in Section 73 for
additional information.
Engine coolant level
Make sure the coolant level is between
the “F” and “L” lines on the seethrough
reservoir when the engine is cold. See
page 326 in Section 72 for additional
information.
Radiator, condenser and hoses

If the headlights or other electrical
components do not work, check the
fuses. If any of the fuses are blown,
they must be replaced.
See “Fuse locations” on page 318 in Sec-
tion 71 for locations of the fuses.
Turn the ignition switch and inoperative
component off. Pull a suspected fuse
straight out and check it.
Determine which fuse may be causing the
problem. The lid of the fuse box shows
the name of the circuit for each fuse. See
page 356 in Section 8 of this manual for
the functions controlled by each circuit. Type A fuses can be pulled out by using
the pullout tool. The location of the pull
out tool is shown in the illustration.
If you are not sure whether the fuse has
blown, try replacing the suspected fuse
with one that you know is good.
If the fuse has blown, push a new fuse
into the clip.
Only install a fuse with the amperage rat-
ing designated on the fuse box lid.
If you do not have a spare fuse, in an
emergency you can pull out the “PWR
OUTLET” or “HEATER NO.2” fuse, which
may be dispensable for normal driving,
and use it if its amperage rating is the
same.
If you cannot use one of the same amper-
age, use one that is lower, but as close
as possible to the rating. If the amperage
is lower than that specified, the fuse
might blow out again but this does not
indicate anything wrong. Be sure to get
the correct fuse as soon as possible and
return the substitute to its original clip.
It is a good idea to purchase a set of
spare fuses and keep them in your ve-
hicle for emergencies.

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.
CAUTION
To prevent burning yourself, do not
replace the light bulbs while they
are hot.
Halogen bulbs have pressurized gas
inside and require special handling.
They can burst or shatter if
scratched or dropped. Hold a bulb
only by its plastic or metal case.
Do not touch the glass part of a
bulb with bare hands.
NOTICE
Only use a bulb of the listed type.
The inside of the lens of exterior lights
such as headlights may temporarily fog up
when the lens becomes wet in the rain or
in a car wash. This is not a problem
because the fogging is caused by the
temperature difference between the outside
and inside of the lens, just like the
windshield fogged up in the rain. However,
if there is a large drop of water on the
inside of the lens, or if there is water
pooled inside the light, contact your
Toyota dealer.
