be a layer of water between the tires and the road surface, preventing the steering and
brakes from operating properly.

Trailer towing (with towing hitch)
Contact your Lexus dealer for further information about additional requirements
such as towing kits, etc.
Your vehicle is designed primarily as a passenger-and-load-carrying vehicle.
Towing a trailer can have an adverse impact on handling, performance, brak-
ing, durability, and fuel co
nsumption. For your safety and the safety of others,
you must not overload your vehicle or trailer. You must also ensure that you
are using appropriate towing equipment, that the towing equipment has been
installed correctly and used properly, and that you employ the requisite driv-
ing habits.
Vehicle-trailer stability and braking performance are affected by trailer sta-
bility, brake performance and setting, trailer brakes, the hitch and hitch sys-
tems (if equipped).
To tow a trailer safely, use extreme care and drive the vehicle in accordance
with your trailer’s characteristics and operating conditions.
Lexus warranties do not apply to damage or malfunction caused by towing a
trailer for commercial purposes.

■Daytime running light system
●To make your vehicle more visible to other drivers during daytime driving, the daytime
running lights turn on automatically whenev
er the engine is started and the parking
brake is released with the headlight switch off (type B only) or in the “AUTO” position.
(Illuminate brighter than the parking lights. ) Daytime running lights are not designed for
use at night.
For the U.S.A.: Daytime running lights can be turned off by operating the switch.
●Compared to turning on the headlights, the daytime running light system offers greater
durability and consumes less electricity, so it can help improve fuel economy.
■Headlight control sensor
■Automatic light off system
●When only the tail lights are on: All lights turn off if the engine switch is turned to
ACCESSORY mode or turned of f and the driver’s door is opened.

■Automatic headlight leveling system
The level of the headlights is automatically adjusted according to the number of passen-
gers and the loading condition of the vehicle to ensure that the headlights do not inter-
fere with other road users.
■If the automatic headlight leveling system warning light flashes
It may indicate a malfunction in the system. Contact your Lexus dealer.
■Welcome lighting
If the headlight switch is turned to AUTO an d the surrounding area is dark, unlocking the
doors using the smart access system with push-button start or wireless remote control
will turn the parking lights an d tail lights on automatically.
■Customization
Settings (e.g. light sensor sensitivity) can be changed.
(Customizable features: →P. 5 9 4 )
The sensor may not function properly if an
object is placed on the sensor, or anything that
blocks the sensor is affixed to the windshield.
Doing so interferes with the sensor detecting
the level of ambient light and may cause the
automatic headlight system to malfunction.
NOTICE
■To prevent battery discharge
Do not leave the lights on longer than ne
cessary when the engine is not running.

Before refueling the vehicle
CAUTION
■When refueling the vehicle
Observe the following precautions while refueling the vehicle. Failure to do so may
result in death or serious injury.
●After exiting the vehicle and before opening the fuel door, touch an unpainted metal
surface to discharge any static electricity. It is important to discharge static electricity
before refueling because sparks resulting fr om static electricity can cause fuel vapors
to ignite while refueling.
●Always hold the grips on the fuel tank cap and turn it slowly to remove it.
A whooshing sound may be heard when the fuel tank cap is loosened. Wait until the
sound cannot be heard before fully removing the cap. In hot weather, pressurized fuel
may spray out of the filler neck and cause injury.
●Do not allow anyone that has not discharged static electricity from their body to come
close to an open fuel tank.
●Do not inhale vaporized fuel.
Fuel contains substances that are harmful if inhaled.
●Do not smoke while refueling the vehicle.
Doing so may cause the fuel to ignite and cause a fire.
●Do not return to the vehicle or touch any person or object that is statically charged.
This may cause static electricity to build up , resulting in a possible ignition hazard.

●Unlocking the vehicle using an electronic key and turning the engine switch to
IGNITION ON mode will recall that key’s registered air conditioning settings.
●When the engine switch is turned off, the current air conditioning settings will automat-
ically be registered to the electronic key that was used to unlock the vehicle.

after the “AUTO” button is pressed.
■When the outside temperature exceeds 75 °F (24 °C) and the air conditioning system
is on
●In order to reduce the air conditioning power consumption, the air conditioning system
may switch to recirculated air mode automatically.

●It is possible to switch to outsid e air mode at any time by pressing or
.
■Fogging up of the windows
●The windows will easily fog up when the humidity in the vehicle is high. Touching “A/C”

●The windows may fog up if the recirculated air mode is used.
■Outside/recirculated air mode
●When driving on dusty roads such as tunnels or in heavy traffic, set the outside/recircu-
lated air mode button to the recirculated air mode. This is effective in preventing out-
side air from entering the vehicle interi or. During cooling operation, setting the
recirculated air mode will also cool the vehicle interior effectively.
●Outside/recirculated air mode may automatically switch depending on the tempera-
ture setting or the inside temperature.
