NOTICE
■To prevent damage to the engine and its components
●Do not let the indicator needle of the tachometer enter the red zone, which indicates
the maximum engine speed.
●The engine may be overheating if the engine coolant temperature gauge is in the red zone (H). In this case, immediately stop the vehicle in a safe place, and check the
engine after it has cooled completely. ( P. 718)

WARNING
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 with the 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 the 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 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 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 control, but the power assist to these systems will be lost. This will make it more difficult 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. 657
●Use engine braking (downshift) to maintain a safe speed when driving down a steep
hill. Using the brakes continuously may caus e the brakes to overheat and lose effec- tiveness. ( P. 251)
●Do not adjust the positions of the steering wheel, 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 o ff-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.

WARNING
Observe the following precautions. Failure to do so may 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 equi pped professional as soon as possible. Rotor damage may result if the pads are not replaced when needed.
Front brakes only: Moderate levels of brake pad and disc wear allow enhanced front braking power. As a result, the discs may wear more quickly than conventional brakediscs. Therefore, 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 th e wear limits of the brake pads and/or those of the brake discs are exceeded.
■When the vehicle is stopped
●Do not race the engine.If the shift lever is in any position other than P or N, the vehicle may accelerate sud-
denly and unexpectedly, causing an accident.
●In order to prevent accidents due to the vehicle rolling away, always keep depressing the brake pedal while the engine is running, and apply the parking brake as neces-
sary.
●If the vehicle is stopped on an incline, in order to prevent accidents caused by the vehicle rolling forward or backward, alwa ys depress the brake pedal and securely
apply the parking brake as needed.
●Avoid revving or racing the engine. Running the engine at high speed while the vehicle is stopped may cause the exhaust
system to overheat, which could result in a fire if combustible material is nearby.

RX350/RX200t_EE_OM48F32E
■Important points regarding stability
Vehicle movement resulting from unev en road surfaces and strong cross-
winds will affect handling. The vehicle may also be rocked by passing buses or
large trucks. Frequently check behind when moving alongside such vehicles.
As soon as such vehicle movement occurs, immediately start to decelerate
smoothly by slowly applying the brakes. Always steer the vehicle straight
ahead while braking.
■Passing other vehicles
Consider the total combined length of your vehicle and trailer and ensure that
the vehicle-to-vehicle distance is sufficient before executing lane changes.
■Transmission information
To maintain engine braking efficiency and charging system performance,
when using engine braking, do not use the transmission in D. If in the M mode,
the transmission shift range position must be in 4 or lower. ( P. 251)
■If the engine overheats
Towing a loaded trailer up a long, steep incline in temperatures exceeding
30 C (85F) may result in the engine overheating. If the engine coolant tem-
perature gauge indicates that the engine is overheating, turn the air condition-
ing off immediately, leave the road and stop the vehicle in a safe place.
( P. 718)
■When parking the vehicle
Always place wheel chocks under the wheels of both the vehicle and trailer.
Set the parking brake and shift the shift lever to P.

■Auto power off function
If the vehicle is left in ACCESSORY mode for more than 20 minutes or IGNITION ON mode (the engine is not running) for more than an hour with the shift lever in P, the engineswitch will automatically turn off. However, this function cannot entirely prevent battery
discharge. Do not leave the vehicle with the engine switch in ACCESSORY or IGNI- TION ON mode for long periods of time when the engine is not running.

■If the engine does not start
●The engine immobilizer system may not have been deactivated. (P. 77) Contact any authorized Lexus dealer or repairer, or another duly qualified andequipped professional.
●Check that the shift lever is securely set in P. The engine may not start if the shift lever is displaced out of P. “To Start Vehicle, Put Shift Lever into P” will be displayed on themulti-information display.
■Steering lock
After turning the engine switch off and opening and closing the doors, the steering wheel will be locked due to the steering lock functi on. Operating the engine switch again auto-
matically cancels the steering lock.
■When the steering lock cannot be released
■Steering lock motor overheating prevention
To prevent the steering lock motor from over heating, operation of the motor may be sus-
pended if the engine is turned on and off repeat edly in a short period of time. In this case, refrain from operating the engine switch. After about 10 seconds, the steering lockmotor will resume functioning.
■When “Smart Entry & Start System Malfunction See Owner’s Manual” is displayed onthe multi-information display
The system may be malfunctioning. Have the vehicle inspected by any authorized Lexus
dealer or repairer, or another duly qua lified and equipped professional immediately.
“Steering Wheel Lock Press Engine Switch while Turning Wheel” will be displayed on themulti-information display.
