Daytime Running Light  (DRL) system
(all models sold in Canada and some
models sold in U.S.A.)
The 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 differ-
ent driving conditions, but they can be
especially helpful in the short periods after
dawn and before sunset.
The DRL system will make the headlights
come on when:
The engine switch is on with the en-
gine running.
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 position 2 or turn the engine switch off.
High Low 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 engine switch 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.
If the turn signal indicator lights (green
lights) on the instrument panel flash faster
than normal, a front or rear turn signal
bulb is burned out.

bulb is burned out.To adjust the headlight beam level, turn
the dial.
The following list shows examples of prop-
er dial settings. For loading conditions oth-
er than those listed, adjust the dial posi-
tion so that the beam level is the same
as the one obtained according to the list
when only the driver is in the vehicle. The
higher the number of the dial position, the
lower the headlight beam level.
Always keep the headlight beam at the
proper level, or your headlights may
dazzle other road users.

The following illustrations show how to
gain access to the bulbs. When replacing
a bulb, make sure the engine  switch and
light switch are off.  Use bulbs  with the
wattage ratings given in the table.
The high mounted stoplight consists of a
number of LEDs. If any of the LEDs burn
out, take your vehicle to your Toyota deal-
er to have the light replaced.
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.
When replacing the rear light bulbs,
turn off the power back door sys-
tem to prevent an unexpected seri-
ous injury.
Vehicles with discharge headlights—
Do not touch the high intensity dis-
charge headlight’s high voltage
socket when the headlights are
turned on. An extremely high volt-
age of 20000 V will be discharged
and could result  in serious  injury or
death by electric shock.
Do not attempt to take apart or re-
pair the low beam headlight bulbs,
connectors, power supply circuits,
or related components.  Doing so
could result in electric shock and
serious injury or death. Call your
Toyota dealer for headlight repair or
servicing, including replacement of
bulbs and bulb disposal.
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 fogs 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.
