Observe the following precautions.
Failure to do so may result in death or serious injury. ■
When starting the vehicle
Always keep your foot on the brake pedal while stopped engine running. This prevents
the vehicle from creeping. ■
When driving the vehicle ●
Do not drive if you are unfamiliar with the location of the brake and accelerator ped-
als to avoid depressing the wrong pedal.
• Accidentally depressing th e accelerator pedal instead of the brake pedal will
result in sudden acceleration that may lead to an accident.
• When backing up, you may twist your body around, leading to difficulty in operat-
ing the pedals. Make sure to operate the pedals properly.
• Make sure to keep a correct driving posture even when moving the vehicle only
slightly. This allows you to depress th e brake and accelerator pedals properly.
• Depress the brake pedal using your righ t foot. Depressing the brake pedal using
your left foot may delay response in an emergency, resulting in an accident. ●
Do not drive the vehicle over or stop the vehicle near flammable materials.
The exhaust system and exhaust gases can be extremely hot. These hot parts may
cause a fire if there is any flammable material nearby. ●
During normal driving, do not turn off the engine. Turning the engine off while driving
will not cause loss of steering or braking co ntrol, but the power assist to these systems
will be lost. This will make it more difficul t to steer and brake, so you should pull over
and stop the vehicle as soon as it is safe to do so.
However, in the event of an emergency, such as if it becomes impossible to stop the
vehicle in the normal way:  P. 6 2 5●
Use engine braking (downshift) to maintain a safe speed when driving down a steep
hill.
Using the brakes continuously may cause th e brakes to overheat and lose effective-
ness. (  P. 2 2 9 )●
Do not adjust the positions of the steering wh eel, the seat, or the inside or outside rear
view mirrors while driving.
Doing so may result in a loss of vehicle control. ●
Always check that all passengers’ arms, heads or other parts of their body are not
outside the vehicle. ●
AWD models: Do not drive the vehicle off-road.
This is not an AWD vehicle designed for of f-road driving. Proceed with all due cau-
tion if it becomes unavoidable to drive off-road. ●
Do not drive across a river or through other bodies of water.
This may cause electric/electronic components to short circuit, damage the engine or
cause other serious damage to the vehicle. ●
Do not drive in excess of the speed limit. Ev en if the legal speed lim it permits it, do not
drive over 85 mph (140 km/h) unless your vehicle has high-speed capability tires.
Driving over 85 mph (140 km/h) may result in tire failure, loss of control and possible
injury. Be sure to consult a tire dealer to determine whether the tires on your vehicle
are high-speed capability tires or not before driving at such speeds.

Matching trailer ball height to trailer coupler height
■
Before towing
Check that the followin g conditions are met:●
Ensure that your vehicle’s tires are properly inflated. (  P. 6 8 0 )●
Trailer tires are inflated according to the trailer manufacturer’s recommendation. ●
All trailer lights work as required by law. ●
All lights work each time you connect them. ●
The trailer ball is set at the proper height for the coupler on the trailer.●
The trailer is level when it is hitched.
Do not drive if the trailer is not level, an d check for improper to ngue weight, overload-
ing, worn suspension, or other possible causes. ●
The trailer cargo is securely loaded. ●
The rear view mirrors conform to all applicable federal, state/provincial or local regula-
tions. If they do not, install rear view mirrors appropriate for towing purposes. ■
AVS (adaptive variable suspension system) (if equipped)
The suspension can be switched fo r improvement in driveability. (  P. 3 7 5 )No matter which class of tow hitch
applies, for a more safe trailer hookup,
the trailer ball setup must be the proper
height for the coupler on the trailer.

248 4-3. Operating the lights and wipers
RX350_U_OM48E90U ●
In the following situations the system may not be able to correctly detect the surround-
ing brightness level. This may cause the lo w beams to remain on or the high beams to
flash or dazzle pedestrians or vehicles ahead. In such a case, it is necessary to manually
switch between the high and low beams.
• When driving in inclement weather (hea vy rain, snow, fog, sandstorms, etc.)
• When the windshield is obscured by fog, mist, ice, dirt, etc.
• When the windshield is cracked or damaged
• When the camera sensor is deformed or dirty
• When the temperature of the camera sensor is extremely high
• When the surrounding brightness level is equa l to that of headlights, tail lights or fog
lights
• When headlights or tail lights of vehicles ah ead are turned off, dirty, changing color,
or not aimed properly
• When the vehicle is hit by water, snow, dust, etc. from a preceding vehicle
• When driving through an area of intermit tently changing brightness and darkness
• When frequently and repeatedly driving ascending/descending roads, or roads with
rough, bumpy or uneven surfaces (such as stone-paved roads, gravel roads, etc.)
•When frequently and repe atedly taking curves or driving on a winding road
• When there is a highly reflective object ahead of the vehicle, such as a sign or mirror
• When the back of a preceding vehicle is hi ghly reflective, such as a container on a
truck
• When the vehicle's headlights are damaged or dirty, or are not aimed properly
• When the vehicle is listing or titling due to a flat tire, a trailer being towed, etc.
• When the headlights are changed between the high beams and low beams repeat-
edly in an abnormal manner
• When the driver believes that the high beams may be flashing or dazzling pedestri-
ans or other drivers■
Temporarily lowering sensor sensitivity
The sensitivity of the sensor can be temporarily lowered.
Turn the engine switch off while the following conditions are met.
• The headlight switch is in or .
• The headlight switch lever is in high beam position.
• Automatic High Beam switch is on.
Turn the engine switch to IGNITION ON mode.
Within 30 seconds after , re peat pulling the headlight sw itch lever to the original
position then pushing it to the high beam po sition quickly 10 times, then leave the lever
in high beam position.
If the sensitivity is changed, the Automatic High Beam indicator is turn on and off 3
times.
Automatic High Beam (headlights) may turn on even the vehicle is stopped.1

When using the Lexus parking assist monitor system
The parking assist monitor is a supplemental device intended to assist the driver when
backing up. When backing up, be sure to chec k visually behind and all around the vehi-
cle before proceeding.
Observe the following precautions to avoid an accident that could result in death or
serious injuries. ●
Never depend on the parking assist monitor entirely when backing up. The image
and the position of the guide lines displaye d on the screen may differ from the actual
state.
Use caution, just as you would when backing up any vehicle. ●
Be sure to back up slowly, depressing the brake pedal to control vehicle speed. ●
If you seem likely to hit nearby vehicles, obstacles, people or mount the shoulder,
depress the brake pedal to stop the vehicle. ●
The instructions given are only guidelines.
When and how much to turn the steering wheel will vary according to traffic condi-
tions, road surface conditions, vehicle condit ion, etc. when parking. It is necessary to
be fully aware of this before using the parking assist system. ●
When parking, be sure to check that the par king space will accommodate your vehi-
cle before maneuvering into it. ●
Do not use the parking assist monitor in the following cases:
• On icy or slick road surfaces, or in snow
• When using tire chains or emergency tires
• When the back door is not closed completely
• On roads that are not flat or straight, such as curves or slopes. ●
In low temperatures, the screen may darken or the image may become faint. The
image could distort when the vehicle is moving, or you may become unable to see the
image on the screen. Be sure to check dire ct visually and with the mirrors all around
the vehicle before proceeding. ●
If the tire sizes are changed, the position of the guide lines displayed on the screen
may change. ●
The camera uses a special lens. The dist ances between objects and pedestrians that
appear in the image displayed on the screen will differ from the actual distances.
(  P. 3 4 7 ) ●
Estimated course line display mode: If the st eering wheel is straight and the vehicle
width guide lines and the estimated course li nes are not in alignment, have the vehicle
inspected by your Lexus dealer.
