Intrusion sensor and tilt sensor
●The intrusion sensor detects an intruder or movement in the vehicle.
●The tilt sensor detects changes in vehicle inclination, such as when the
vehicle is towed away.
This system is designed to deter and prevent vehicle theft but does not
guarantee absolute security against all intrusions.
The intrusion sensor and tilt sensor can be canceled using the cancel
switch.
Vehicles without a navigation system
Close the doors and hood, and
lock all the doors using the entry
function or wireless remote
control. The system will be set
automatically after 30 seconds.
The indicator light changes from
being on to flashing when the
system is set.
■Deactivating or stopping the alarm

CAUTION
■SRS airbag precautions
Observe the following precautions regarding the SRS airbags.
Failure to do so may cause death or serious injury.
●The driver and all passengers 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.
Since the risk zone for driver’s airbag is the first 50 - 75 mm (2 - 3 in.) of inflation,
placing yourself 250 mm (10 in.) 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 250 mm (10 in.) 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 drivers can achieve the 250 mm (10 in.)
distance, even with the driver 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, non-slippery cushion, or raise the
seat if your vehicle has that feature.
• If your steering wheel is adjustable, tilt it downward. This points the airbag
toward your chest instead of your head and neck.
The seat should be adjusted as recommended above, while still maintaining con-
trol of the foot pedals, steering wheel, and your view of the instrument panel con-
trols.
●The portion of the front pillars, rear pillars
or roof side rail garnishes (padding) con-
taining the curtain shield airbags inside is
scratched, cracked, or otherwise dam-
aged.

■“PASSENGER AIR BAG” indicator information
If any of the following problems occur, it is possible that there is a malfunction in the
system. Have the vehicle inspected by any authorized Lexus dealer or repairer, or
another duly qualified and equipped professional.
●Neither “ON” nor “OFF” comes on.
●The indicator does not change when the airbag manual on-off switch is
switched to “ON” or
“OFF”.
CAUTION
■When installing a child restraint system
For safety reasons, always install the child restraint system in a rear seat. In the event
that the rear seat cannot be used, the front seat can be used as long as the airbag
manual on-off system is set to “OFF”.
If the airbag manual on-off system is left on, the strong impact of the airbag deploy-
ment (inflation) may cause death or serious injury.
■When a child restraint system is not installed on the front passenger seat
Ensure that the airbag manual on-off system is set to “ON”.
If it is left
off, the airbag may not deploy in the event of an accident, which may result
in death or serious injury.

■Eco-friendly driving
■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 )
●The vehicle speed is approximately 130
km/h (80 mph) or higher.

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.

following serious damage to the vehicle:
●Engine stalling
●Short in electrical components

●Brake function
●Changes in quantity and quality of oil and fluid used for the engine, transaxle,
transfer (AWD models), differential, etc.
●Lubricant condition for the propeller shaft (AWD models), bearings and suspen-
sion joints (where possible), and the function of all joints, bearings, etc.
