Before driving
■Conditions affecting operation
In the following situations, the wireless remote control may not operate properly:
●Near a TV tower, electric power plant, broadcasting station, airport or other
facility that generates strong radio waves or electrical noise, an audio or other
radio wave emitting device or a large display
●When carrying a portable radio, cellular phone, cordless phone or other wire-
less communication device
●When multiple wireless remote controls are in the vicinity
●When the wireless remote control is in contact with, or is covered by certain
metallic objects
●When another wireless remote control (that emits radio waves) is being used
nearby
■When riding in an aircraft
When bringing a wireless remote control function onto an aircraft, make sure you
do not press any buttons on the wireless remote control while inside the aircraft
cabin. If you are carrying the wireless remote control in your bag etc, ensure that
the buttons are not likely to be pressed accidentally. Pressing a button may cause
the wireless remote control to emit radio waves that could interfere with the opera-
tion of the aircraft.
■Customization that can be conf igured at your Lexus dealer
Settings (e.g. door unlocking function and door lock buzzer sound) can be
changed. (Customizable features P. 383)

1-6. Theft deterrent system
Tilt sensorThe tilt sensor detects changes in vehicle inclination, such as when the
vehicle is towed away.
This system is designed to deter and p revent vehicle theft but does not
guarantee absolute security against all tilts.
The tilt sensor can be canceled using the cancel switch.
Canceling the tilt sensor
Remove the key from the ignition
switch and press the tilt sensor
cancel switch in the glove box.
To set the alarm with the tilt sensor
disabled, the alarm must be set
within 5 minutes after canceling
the sensor.
The tilt sensor will revert to on each
time the ignition switch is turned to
the “ON” position.
To cancel the tilt sensor, perform the necessary procedure each time
canceling the sensors is desired.

1-7. Safety information
CAUTION
■SRS airbag precautions
Observe the following precautions regarding the airbags.
Failure to do so may cause death or serious injury.
●The driver and passenger in the vehicle must wear their seat belts properly.
The SRS airbags are supplemental devices to be used with the seat belts.
●The SRS driver airbag deploys with considerable force, and can cause death or
serious injury especially if the driver is very close to the airbag. The National
Highway Traffic Safety Administration (“NHTSA”) advises:
Since the risk zone for the driver airbag is the first 2 - 3 in. (50 - 75 mm) of infla-
tion, placing yourself 10 in. (250 mm) from your driver airbag provides you with a
clear margin of safety. This distance is measured from the center of the steering
wheel to your breastbone. If you sit less than 10 in. (250 mm) away now, you can
change your driving position in several ways:
• Move your seat to the rear as far as you can while still reaching the pedals
comfortably.
• Slightly recline the back of the seat. Although vehicle designs vary, many dr ivers can achieve the 10 in. (250 mm)
distance, even with the driver’s seat all the way forward, simply by reclining
the back of the seat somewhat. If reclining the back of your seat makes it hard
to see the road, raise yourself by using a firm, or raise the seat if your vehicle
has that feature.
• If your steering wheel is adjustable, ti lt it downward. This points the airbag
toward your chest instead of your head and neck.
The seat should be adjusted as recommended by NHTSA above, while still main-
taining control of the foot pedals, steering wheel, and your view of the instrument
panel controls.

2-3. Operating the lights and windshield wipers
■If there is a system malfunction
“Check wiper system” will be shown on the meter. (P. 325)
NOTICE
■When the windshield is dry
Do not use the wipers, as they may damage the windshield.
■When there is no washer fluid spray from the nozzle
Damage to the washer fluid pump may be caused if the lever is pulled toward you
and held continually.
■Lifting the wiper
Make sure that the wiper is stopped near the
upper reverse position.
Do not lift up the wiper if it is in the retracted
position, because the wiper blade or front pil-
lar fin may be damaged.

2-5.Driving information
Cargo and luggage
Take notice of the following information about storage precautions, cargo
capacity and load:
●Stow cargo and luggage in the luggage compartment whenever possi-
ble.
● Be sure all items are secured in place.
● To maintain vehicle balance while driving, position luggage evenly
within the luggage compartment.
● For better fuel economy, do not carry unnecessary weight.
Capacity and distribution
Cargo capacity depends on the to tal weight of the occupants.
(Cargo capacity) = (Total load capa city) — (Total weight of occupants)
Steps for Determining Correct Load Limit 
(1) Locate the statement “The combined weight of occupants and cargo should never exceed XXX kg or XXX lbs.” on your vehicle’s placard.
(2) Determine the combined weight of th e driver and passengers that will
be riding in your vehicle.
(3)Subtract the combined weight of the driver and passengers from
XXX kg or XXX lbs.
(4)The resulting figure equals the av ailable amount of cargo and luggage
load capacity.
For example, if the “XXX” amount equals 1400 lbs. and there will be
five 150 lb passengers in your vehicle, the amount of available cargo
and luggage load capacity is 650 lbs. (1400  750 (5150) = 650
lbs.)
(5)Determine the combined weight of luggage and cargo being loaded
on the vehicle. That weight may no t safely exceed the available cargo
and luggage load capacity calculated in Step 4.

When driving
(6)If your vehicle will be towing a trailer, load from your trailer will betransferred to your vehicle. Consul t this manual to determine how this
reduces the available cargo and luggage load capacity of your vehi-
cle.
Lexus does not recommend towing a trailer with your vehicle. Your vehicle is
not designed for trailer towing.
Example based on your vehicle
Cargo capacity
Total load capacity
When 1 person with the weight of 176 lb. (80 kg) is riding in your vehicle,
which has a total load capacity of 34 5 lb. (155 kg), the available amount
of cargo and luggage load capacity will be as follows:
345 lb. — 176 lb. = 169 lb. (155 kg —80 kg = 75 kg)
In this condition, if 1 more occupant wi th the weight of 154 lb. (70 kg) gets on,
the available cargo and luggage load will be reduced as follows:
169 lb. — 154 lb. = 15 lb. (75 kg — 70 kg = 5 kg)
As shown in the above example, if the number of occupants increases,
the cargo and luggage load equaling the weight of the occupant who got
on later, by an amount. In other wo rds, if an increase in the number of
occupants causes an excess of the total load capacity (combined weight
of occupants plus cargo and luggage load), you must reduce the cargo
and luggage on your vehicle.
