Operation of each component
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.
●Do not attach any accessories other than genuine Lexus parts to the trunk lid. Such
additional weight on the trunk lid may cause the lid to suddenly shut again after it is
opened.
●The trunk lid may suddenly shut if it is notopened fully. It is more difficult to open or
close the trunk lid on an incline than on a level
surface, so beware of the trunk lid unexpect-
edly opening or closin g by itself. Make sure
that the trunk lid is fully open and secure
before using the trunk.
●When closing the trunk li d, take extra care to
prevent your fingers etc. from being caught.
●When closing the trunk lid, make sure to
press it lightly on its outer surface. If the trunk
grip is used to fully close the trunk lid, it may
result in hands or arms being caught.

WARNING
■Trunk easy closer
■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 any-
thing that could cause any of yo
ur 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 while 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 suddenly sh ut after it opens automatically. Make sure
the trunk lid is fully open and secure before using the trunk.
●In the following situations, the power trun k opener and closer may detect an abnor-
mality and automatic operation may be stoppe d. In this case, the trunk lid has to be
operated manually. Take extra care in this situation, as the stopped trunk lid may sud-
denly shut, causing an accident.
• When the trunk lid contacts an obstacle
• When the battery voltage suddenly drops, such as when the engine switch is turned to IGNITION ON mode or the engine is started during automatic opera-
tion
●Do not attach any accessories other than genuine Lexus parts to the trunk lid. The
power trunk opener and closer may not operate, causing itself to malfunction, or the
trunk lid may suddenly shut again after it is opened.
■Jam protection function (vehicles with power trunk opener and closer)
Observe the following precautions.
Failure to do so may cause serious injury.
●Never use any part of your body to intentionally activate the jam protection function.
●The jam protection function may not work if something gets caught just before the
trunk lid fully closes. Be careful not to catc h fingers or anything else in the trunk lid.
●The jam protection function may not work depending on the shape of the object that
is caught. Be careful not to catch fingers or anything else.
In the event that the trunk lid is left slightly open,
the trunk easy closer will automatically close it
to the fully closed position. It takes several sec-
onds before the trunk easy closer begins to
operate. Be careful not to catch fingers or any-
thing else in the trunk lid, as this may cause
bone fractures or other serious injuries.

Driving
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 a difficulty in oper-
ating the pedals. Make sure to operate the pedals properly.
• Make sure to keep a correct driving po sture 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. 425
●Use engine braking (downshift) to maintain a safe speed when driving down a steep
hill.
Using the brakes continuously may cause th e brakes to overheat and lose effective-
ness. ( P. 208)
●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, he ads 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 no t before driving at such speeds.

GS350_GS F_OM_OM30J07U_(U)4-1. Before driving
WARNING
Observe the following precautions.
Failure to do so may result in death or serious injury.
■When driving on slippery road surfaces
●Sudden braking, acceleration and steering 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 pe dal to make sure that the
brakes are functioning properly. Wet brake pads may prevent the brakes from func-
tioning properly. If the brakes on only on e side are wet and not functioning properly,
steering control may be affected.
■When shifting the shift lever
●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 accide nt or damage to the vehicle.
●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 a driving position while the vehicle is moving backward.
Doing so can damage the transmission and may result in a loss of vehicle control.
●Moving the shift lever to N while the vehicle is moving will disengage the engine from
the transmission. Engine braking is not available when N is selected.
●Be careful not to shift the shift lever with the accelerator pedal depressed. Shifting the
shift lever to a gear other than P or N 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 limit indicators) (GS350)
Have the brake pads checked and replaced by your Lexus dealer as soon as possible.
Rotor damage may result if the pads are not replaced when needed.
Front brakes of F SPORT models: Moderate levels of brake pad and disc wear allow
enhanced front braking power. As a result, the discs may wear more quickly than con-
ventional brake discs. Therefore, when replacing the brake pads, Lexus recommends
that you also have the thic kness 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.
