■Customization 
Setting of Eco Driving Indicator Light can be changed. 
(Customizable features →P.  6 2 2 )
CAUTION
■When starting the vehicle
Always keep your foot on the brake pedal while stopped with the engine running.
This prevents the vehicle from creeping.
During Eco-friendly acceleration (Eco driv-
ing), Eco Driving Indicator Light will turn on.
When the acceleration exceeds Zone of Eco
driving, and when the vehicle is stopped, the
light turns off.
Eco Driving Indicator Light will not operate in
the following conditions:
●The shift lever is in anything other than D.
●The paddle shift switch is operated. (if
equipped)
●The driving mode is set to snow mode.
(→P.  1 8 8 )

2-1. Driving procedures
RX350/270_EE
CAUTION
■When driving the vehicle
●Do not drive if you are unfamiliar with the location of the brake and accelerator
pedals to avoid depressing the wrong pedal. 
• Accidentally depressing the accelerator pedal instead of the brake pedal will
result in sudden acceleration that may lead to an accident that could result in
death or serious injury.
• When backing up, you may twist your body around, leading to a difficulty in
operating 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 the brake and accelerator pedals
properly.
• Depress the brake pedal using your right foot. Depressing the brake pedal
using your left foot may delay response in an emergency, resulting in an acci-
dent.
●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.
●Do not let the vehicle roll backward while the shift lever is in a driving position, or
roll forward while the shift lever is in R. 
Doing so may cause the engine to stall or lead to poor brake and steering perfor-
mance, resulting in an accident or damage to the vehicle. 
●If the smell of exhaust is noticed inside the vehicle, open the windows and check
that the back door is closed. Large amounts of exhaust in the vehicle can cause
driver drowsiness and an accident, resulting in death or a serious health hazard.
Have the vehicle inspected by any authorized Lexus dealer or repairer, or
another duly qualified and equipped professional immediately.
●Do not shift the shift lever to P while the vehicle is moving. 
Doing so can damage the transmission and may result in a loss of vehicle control.
●Do not shift the shift lever to R while the vehicle is moving forward. 
Doing so can damage the transmission and may result in a loss of vehicle control.
●Do not shift the shift lever to D while the vehicle is moving backward. 
Doing so can damage the transmission and may result in a loss of vehicle control.

2-1. Driving procedures
RX350/270_EE
CAUTION
■When driving on slippery road surfaces
●Sudden braking, acceleration and steering may cause tire slippage and reduce
your ability to control the vehicle, resulting in an accident.
●Sudden acceleration, engine braking due to shift changing, or changes in engine
speed could cause the vehicle to skid, resulting in an accident.
●After driving through a puddle, lightly depress the brake pedal to make sure that
the brakes are functioning properly. Wet brake pads may prevent the brakes from
functioning properly. If the brakes on only one side are wet and not functioning
properly, steering control may be affected, resulting in an accident.
■When shifting the shift lever
Be careful not to shift the shift lever with the accelerator pedal depressed. 
This may lead to unexpected rapid acceleration of the vehicle that may cause an
accident and result in death or serious injury.
■If you hear a squealing or scraping noise (brake pad wear indicators)
Have the brake pads checked and replaced by any authorized Lexus dealer or
repairer, or another duly qualified and equipped professional as soon as possible. 
Rotor damage can result if the pads are not replaced when needed.
Moderate levels of brake pad and disc wear allow enhanced front braking power.
As a result, the discs may wear more quickly than conventional brake discs. There-
fore, when replacing the brake pads, Lexus recommends that you also have the
thickness of the discs measured. 
It is dangerous to drive the vehicle when the wear limits of the brake pads and/or
those of the brake discs are exceeded.

RX350/270_EE
CAUTION
■When the vehicle is parked
●Do not leave glasses, cigarette lighters, spray cans, or soft drink cans in the vehi-
cle when it is in the sun. 
Doing so may result in the following:
• Gas may leak from a cigarette lighter or spray can, and may lead to a fire.
• The temperature inside the vehicle may cause the plastic lenses and plastic
material of glasses to deform or crack.
• Soft drink cans may fracture, causing the contents to spray over the interior of
the vehicle, and may also cause a short circuit in the vehicle's electrical com-
ponents.
●Do not leave cigarette lighters in the vehicle. If a cigarette lighter is in a place such
as the glove box or on the floor, it may be lit accidentally when luggage is loaded
or the seat is adjusted, causing a fire.
●Do not attach adhesive discs to the windshield or windows. Do not place contain-
ers such as air fresheners on the instrument panel or dashboard. Adhesive discs
or containers may act as lenses, causing a fire in the vehicle.
●Do not leave a door or window open if the curved glass is coated with a metal-
lized film such as a silver-colored one. Reflected sunlight may cause the glass to
act as a lens, causing a fire.
●Always apply the parking brake, shift the shift lever to P, stop the engine and lock
the vehicle. 
Do not leave the vehicle unattended while the engine is running.
●Do not touch the exhaust pipes while the engine is running or immediately after
turning the engine off. 
Doing so may cause burns.
●Do not leave the engine running in an area with snow build-up, or where it is
snowing. If snowbanks build up around the vehicle while the engine is running,
exhaust gases may collect and enter the vehicle. This may lead to death or a seri-
ous health hazard.
