WARNING ■
Caution for use while driving ●
When operating the multi-information display while driving, pay extra attention to the
safety of the area around the vehicle. ●
Do not look continuously at the multi-info rmation display while dr iving as you may fail
to see pedestrians, objects on the road, etc. ahead of the vehicle. ■
The information display at low temperatures
Allow the interior of the vehicle to warm up before using the liquid crystal information
display. At extremely low temperatures, th e information display monitor may respond
slowly, and display changes may be delayed.
For example, there is a lag between the dr iver’s shifting and the new gear number
appearing on the display. This lag could ca use the driver to downshift again, causing
rapid and excessive engine braking and possibly an accident resulting in death or
injury. ■
Cautions during setting up the display
As the engine needs to be running during sett ing up the display, en sure that the vehicle
is parked in a place with adequate ventilation. In a closed area such as a garage,
exhaust gases including harmful carbon mo noxide (CO) may collect and enter the
vehicle. This may lead to death or a serious health hazard.
NOTICE ■
While setting up the display
To prevent battery discharge, ensure that the engine is running while setting up the dis-
play features.

Operation of each component
RC F_U 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 th an on a level surface,
so beware of the trunk lid un expectedly opening or closin g 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. Such
additional 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 other
part of the body.
●
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
handle is used to fully close the trunk lid, it
may result in hands or arms being caught.

Driving
RC F_U 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 th e brake and accelerator pedals properly.
• Depress the brake pedal using your right foot. Depressing the brake pedal using
your left foot may delay re sponse 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 engi ne 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. 443●
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. 213)●
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.

196 4-1. Before driving
RC F_U 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. ●
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 posi tion 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 limi t indicators) (RC350/
RC300)
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 on F SPORT models (RC3 50 [2WD]/RC300 [2WD] only): Moderate
levels of brake pad and disc wear allow enhanced front braking power. As a result, the
discs may wear more quickly than convention al brake discs. Therefore, when replacing
the brake pads, Lexus recommends that you al so have the thickness of the discs mea-
sured.
It is dangerous to drive the vehicle when the wear limits of the brake pads and/or those
of the brake discs are exceeded.
