RC200t_RC F_EE(OM24728E)
WARNING
■Using the trunk
Observe the following precautions. Failure to do so may cause parts of the body to be caught, resulting in serious injury.
●Remove any heavy loads, such as snow and ice, from the trunk lid before opening it. Failure to do so may cause the trunk lid to suddenly shut again after it is opened.
●When opening or closing the trunk lid, thoroughly check to make sure the surround-
ing area is safe.
●If anyone is in the vicinity, make sure they are safe and let them know that the trunk is about to open or close.
●Use caution when opening or closing the tr unk lid in windy weather as it may move abruptly in strong wind.
●On an incline it is more difficult to open or close the trunk lid than on a level surface,
so beware of the trunk lid unexpectedly op ening or closing by itself. Make sure that the trunk lid is fully open and secure before using the trunk.
●Do not attach any accessories other than genuine Lexus parts to the trunk lid. Suchadditional weight on the trunk lid may cause the lid to suddenly shut again after it is
opened.
●When opening the trunk lid, take care so that it does not hit anyone in the face or any otherpart of the body.
●When closing the trunk lid, take extra care toprevent your fingers etc. from being caught.
●When closing the trunk lid, make sure topress it lightly on its outer surface. If the trunkhandle is used to fully close the trunk lid, it
may result in hands or arms being caught.

WARNING
■When adjusting the seat position
●Take care when adjusting the seat position to ensure that other passengers are not injured by the moving seat.
●Do not put your hands under the seat or near the moving parts to avoid injury.Fingers or hands may become jammed in the seat mechanism.
●Make sure to leave enough space around the feet so they do not get stuck.
■Seat adjustment
To reduce the risk of sliding under the lap be lt during a collision, do not recline the seat more than necessary.
If the seat is too reclined, th e lap belt may slide past the hips and apply restraint forces directly to the abdomen, or your neck may contact the shoulder belt, increasing the riskof death or serious injury in the event of an accident.
Adjustments should not be made while driving as the seat may unexpectedly move and cause the driver to lose control of the vehicle.
■Lever-operated “Front , Fold & Return” seat
●Before operating the lever-operated “Front, Fold & Return” seat, ensure that any sur- rounding passengers or objects will not contact the seat.

WARNING
Observe the following precautions. Failure to do so may result in death or serious injury.
■If a brake pad wear warning message is displayed (RC F)
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.
Moderate levels of the brake pad and disc wear allow enhanced braking power. As a result, the discs may wear more quickly than conventional brake discs. 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 vehicle is in any gear other than P or N, the vehicle may accelerate suddenly
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.

WARNING
Observe the following precautions. Failure to do so may result in death or serious injury.
■When braking
●When the brakes are wet, drive more cautiously.Braking distance increases when the brakes are wet, and this may cause one side ofthe vehicle to brake differently than the other side. Also, the parking brake may not
securely hold the vehicle.
●If the power brake assist function does not operate, do not follow other vehicles closely and avoid hills or shar p turns that require braking.
In this case, braking is still possible, bu t the brake pedal should be depressed more firmly than usual. Also, the braking distance will increase. Have your brakes fixedimmediately.
●Do not pump the brake pedal if the engine stalls. Each push on the brake pedal uses up the reserve for the power-assisted brakes.
●The brake system consists of 2 individual hy draulic systems; if one of the systems fails,
the other will still operate. In this case, the brake pedal should be depressed more firmly than usual and the braking distance will increase. Have your brakes fixed imme- diately.
■If the vehicle becomes stuck
Do not spin the wheels excessively when any of the tires is up in the air, or the vehicle is stuck in sand, mud, etc. This may damage th e driveline components or propel the vehi-
cle forward or backward, causing an accident.

Take notice of the following information about storage precautions, cargo
capacity and load:
WARNING
■Things that must not be carried in the trunk
The following things may cause a fire if loaded in the trunk:
●Receptacles containing gasoline
●Aerosol cans
■Storage precautions
Observe the following precautions. Failure to do so may prevent the pedals from being depressed properly, may block the driver’s vision, or may result in items hitting the driver or passengers, possibly causing
an accident.
●Stow cargo and luggage in the trunk whenever possible.
●RC200t: To prevent cargo and luggage from sliding forward during braking, do not
stack anything in the enlarged trunk. Keep cargo and luggage low, as close to the floor as possible.
●RC200t: When you fold down the rear seats, long items should not be placed
directly behind the front seats.
●RC200t: Never allow anyone to ride in the en larged trunk. It is not designed for pas- sengers. They should ride in their seats with their seat belts properly fastened.
●Do not place cargo or luggage in or on the following locations.
• At the feet of the driver • On the front passenger or rear seats (when stacking items)
• On the package tray • On the instrument panel• On the dashboard
• In front of the navigation or multimedia system screen (if equipped) or Lexus Dis- play Audio screen (if equipped)

■If the engine does not start
●Check that the shift lever is securely set in P. The engine may not start if the shift lever is displaced out of P.

■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 lock motor will resume functioning.
“Steering Lock active” will be displayed on the
multi-information display.
