this device must accept any interference, including
interference that may cause undesired operation of

KEYS AND DOORS
25
BACK DOOR
11PY031
1Halfopen position
2Fullopen position
To open the back door, pull the handle. The back door can
be opened at the above mentioned positions. The back door can be locked and unlocked together with the
side doors by means of the power door lock system. (For
instructions, see “Locking with power door lock switch” on
page 22.)
See “Stowage precautions” on page
419 for precautions when
loading luggage.
CAUTION
 Keep the back door closed while driving. This not
only keeps the luggage from being thrown out but
also prevents exhaust gases from entering the
vehicle.
 If the open back door hides the rear stop and tail
lights or rear turn signal lights while you are parked,
other road users must be warned of the presence of
your vehicle by a warning triangle or other device.

SWITCHES
34Twist the interval adjuster upward to increase the wiping
time
interval between sweeps, and downward to decrease
it.
The wiper lever must be in the “INT” position.
The time interval between sweeps is shortened when the
vehicle speed increases. When the vehicle speed reaches
more than about 20 km/h (12 mph) with the interval adjuster in
the full upward position, the time interval becomes the shortest
1.5 seconds.
If you stop the vehicle with the wiper switch in the “LO” position,
the wiper speed automatically changes from low speed to
variable intermit tent operation sp eed.* This function does not
work when the interval adjuster is in the full upward position.
NOTE:
* This feature can be deactivated.
Ask your Lexus dealer for details.
To make the washer squirt, pull the lever toward you and
release it.
If the wiper lever is in the “OFF” position, the wipers will
automatically make 3 wipes and then a single wipe later to
sweep the windshield completely.* The interval between the
3 wipes and the last wipe will depend on the vehicle speed. The
last sweep does not happen if the vehicle speed exceeds about
170 km/h (106 mph).
NOTE:
* The last single wipe can be deactivated.
Ask your Lexus dealer for details. The low washer fluid warning light in the instrument cluster
comes on when the fluid level in the tank becomes nearly
empty. For information on adding washer fluid, see “Adding
washer fluid” on page 558.
In cold weather, warm the windshield with the defroster before
using the washer. This will help prevent icing, which could
block your vision.
NOTICE
Do not operate the wipers if the windshield is dry. It may
scratch the glass.
