Operation of each component
CAUTION
■Power trunk opener and closer (if equipped)
Observe the following precautions when operating the power trunk opener and
closer.
Failure to do so may cause serious injury.
●Check the safety of the surrounding area to make sure there are no obstacles or
anything that could cause any of your belongings to get caught.
●If anyone is in the vicinity, make sure they are safe and let them know that the
trunk is about to open or close.
●If the trunk closer switch is pressed whil e the trunk lid is opening during automatic
operation, the trunk lid stops opening. Take extra care when on an incline, as the
trunk lid may open or close suddenly.
●On an incline, the trunk lid may fall afte r it opens automatically. Make sure the
trunk lid is fully open and secure before using the trunk.
●In the following situations, the power trunk opener and closer may detect an
abnormality and automatic operation may be stopped. In this case, the trunk lid
has to be operated manually. Take extra care in this situation, as the stopped trunk
lid may suddenly fall, causing an accident.
• When the trunk lid contacts an obstacle
• When the 12-volt battery voltage suddenly drops, such as when the “START STOP ENGINE” <“POWER”> switch is turned to IGNITION ON
mode or the engine is started during automatic operation
●Do not attach any accessories other than genuine Lexus parts to the trunk lid. The
power trunk opener and closer may not op erate, causing itself to malfunction, or
the trunk lid may fall closed again after it is opened.

CAUTION
Observe the following precautions.
Failure to do so may result in death or serious injury.
■When driving the vehicle
●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 syst ems 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. 6 1 5
●Use engine braking (downshift) to maintain a safe speed when driving down a
steep hill.
Using the brakes continuously may cause the brakes to overheat and lose effec-
tiveness. ( P. 223, 227)
●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.
●Do not drive in excess of the speed limit. Even if the legal speed limit 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.
■When driving on slippery road surfaces
●Sudden braking, acceleration and steeri ng may cause tire slippage and reduce
your ability to control the vehicle.
●Sudden acceleration, engine braking due to shifting, 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.

4-1. Before driving
CAUTION
■If you hear a squealing or scraping noise (brake pad wear limit indicators)
Have the brake pads checked and replaced by your Lexus dealer as soon as possi-
ble.
Rotor damage may result if the pads are not replaced when needed.
It is dangerous to drive the vehicle when the wear limits of the brake pads and/or
those of the brake discs are exceeded.
■When the vehicle is stopped
●Gasoline vehicles: 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.
Hybrid vehicles: Do not depress the accelerator pedal unnecessarily.
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 ing>, and apply the parking brake as necessary.
●If the vehicle is stopped on an incline, in order to prevent accidents caused by the
vehicle rolling forward or backward, always depress the brake pedal and securely
apply the parking brake as needed.
●Avoid revving or racing the engine.
Running the engine at high speed whil e the vehicle is stopped may cause the
exhaust system to overheat, which could result in a fire if combustible material is
nearby.
