INFORMATION
Be sure to take the smart key with you.
 In the following cases, the smart key system or
wireless remote control feature may not operate
properly. (If this happens, use a mechanical key to
lock or unlock the doors and trunk lid and a smart key
to start the engine.)
When facilities issuing strong electromagnetic
waves such as TV towers, electric power stations,
broadcasting stations are nearby.
When you are carrying a smart key together with a
mobile communications system such as a
twoway radio or cellular phone.
When the smart key is in contact with or covered
by a metallic object.
When another person is operating a wireless
remote control function on another vehicle near
your vehicle.
 If you do not drive your vehicle, store the smart key,
keeping it at least 5 m (15 ft.) away from the vehicle.
Alarms and warning messages
Your Lexus is equipped with alarms inside and outside, as
well as warning messages in the multiinformation
display, that remind you if there is a problem involving the
smart key system.
Cases which are expected to happen frequently are
shown in the illustrations and the other cases are
described in the table. If an alarm or warning message
comes on, check to see what the problem is referring to
the illustrations and table, and take the appropriate

DOORS
See page 25 for locking the doors with smart key system
and page 28 for unlocking them with smart key system.
Locking with key
11L227
 1Type A 2Type B 3Lock 4Unlock
Turn the key towards the front of the vehicle to lock and
towards the back to unlock.
The doors lock and unlock simultaneously with the driver’s
door. Turning the key once will unlock the driver’s door and
twice in succession will unlock all doors simultaneously.* NOTE:
* The 2step unlocking function can be changed.
Ask your Lexus dealer for details. If a wrong key is used, the key cylinder rotates freely to isolate
inside
mechanism. So, door locking is protected from thieves.
The windows and moon roof can be opened and closed from
outside the vehicle using the key. For details, see “Power
window switches” on page 64 and “Moon roof” on page 148.

SWITCHES
59
The wiper lever must be in the “INT” position.
The time interval between sw
eeps is shortened when the
vehicle speed increases. When the vehicle speed reaches
more than about 20 km/h (12 mph) with the interval adjuster
twisted down to the lowest 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
intermittent operation speed.* This function does not work with
the interval adjuster twisted down to the lowest position.
NOTE:
* This feature can be deactivated.
Ask your Lexus dealer for details.
For mist wiper operations (a single wipe), pull the lever
toward you and release it.
To make the washer squirt, push the button on the end of
the lever.
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 warning message “Low Washer Fluid” is displayed in the
multi−
information display when the fluid level in the tank
becomes very low. For information on adding washer fluid, see
“Adding washer fluid” on page 503.
When the headlights are on and the washers are activated by
pushing the windshield washer switch, the headlight cleaner
operates once automatically.
In cold weather, warm the windshield with the defroster before
using the washer. This will help prevent icing, which could
block your vision.
The rear window and outside rear view mirror defogger
automatically turns on when you operate the wipers.
NOTICE
Do not operate the wipers if the windshield is dry. It may
scratch the glass.

wiper activation.
 Turning the ignition switch on with the wiper lever in the
“AUTO” position.
 Turning the ignition switch on and move the wiper lever
down in the “AUTO” position.
Even with the wiper lever in the “AUTO” position, the system
will switch to intermittent operations if the system malfunctions.
The system will turn off if the windshield gets extremely hot (at
more than 80C or 176F) or cold (at less than –10 C or 14F).
When the ignition switch is turned off with the wiper lever in the
“AUTO” position, and then the ignition switch is turned on
again, the automatic operation may not work even if raindrops
are on the windshield.
In this case, move the lever to another position and return it to
the “AUTO” position again.
CAUTION
Be careful not to get your fingers caught between the
wipers and windshield.
When the wiper lever is in the “AUTO” position with the
ignition switch on, the wipers could operate
automatically in the following cases:
 If you touch the upper center of the windshield
adjacent to the sensor.
 If you wipe the upper center of the windshield
(adjacent to which the sensor is located) with a towel.
 If the windshield vibrates.

Idling for a long period with the air conditioning on in
stop−and−go traffic.
 Towing a trailer.
NOTICE
Do not remove the thermostat in the engine cooling
system as this may cause the engine to overheat. The
thermostat is designed to control the flow of coolant
to keep the temperature of the engine within the
specified operating range.
 Do not continue driving with an overheated engine.
See “If your vehicle overheats” on page 404.
TACHOMETER
13L144
The tachometer indicates engine speed in thousands of
rpm (revolutions per minute). Use it while driving to
prevent engine overrevving.
Driving with the engine running too fast causes excessive
engine wear and poor fuel economy. Remember, in most
cases the slower the engine speed, the greater the fuel
economy.
NOTICE
Do not let the indicator needle get into the red zone. This
may cause severe engine damage.

buildings, roof parking, near a crossing, near a large
vehicle, etc.). 
The vehicle is magnetized. (There is a magnet or a metal
object near the audio system.)
