Driving
RC350/RCF_U (OM24636U)
■When starting off on an uphill
The hill-start assist control will activate. (P. 2 8 2 )
■Driving in the rain
●Drive carefully when it is raining, because visibility will be reduced, the windows may
become fogged-up, and th e road will be slippery.
●Drive carefully when it starts to rain, becau se the road surface will be especially slip-
pery.
●Refrain from high speeds when driving on an expressway in the rain, because there may
be a layer of water between the tires and the road surface, preventing the steering and
brakes from operating properly.
■Engine speed while driving
In the following conditions, the engine speed may become high while driving. This is due
to automatic up-shifting control or down-shi fting implementation to meet driving condi-
tions. It does not indica te sudden acceleration.
●The vehicle is judged to be driving uphill or downhill
●When the accelerator pedal is released
●When the brake pedal is depresse d while sport mode is selected
■Restraining the engine output (brake override system)
●When the accelerator and brake pedals are depressed at the same time, the engine
output may be restrained.
●A warning message is displayed on the multi-information display while the system is
operating. (P. 5 5 0 )
■Breaking in your new Lexus
To extend the life of the ve hicle, observing the followin g precautions is recommended:
●For the first 186 miles (300 km):
Avoid sudden stops.
●For the first 621 miles (1000 km):
• Do not drive at extremely high speeds.
• Avoid sudden acceleration.
• Do not drive continuously in low gears.
• Do not drive at a constant speed for extended periods.
■Drum-in-disc type parking brake system
Your vehicle has a drum-in-disc type parking brake system. This type of brake system
needs bedding-down of the brake shoes periodically or whenever the parking brake
shoes and/or drum are replaced. Have your Lexus dealer perform the bedding down
operation.
■Operating your vehicle in a foreign country
Comply with the relevant vehi cle registration laws and confirm the availability of the cor-
rect fuel. ( P. 6 2 0 )
■Brake pads and discs (RC F)
The brake pads and discs are designed for use under high load conditions. Therefore,
brake noise may be generated depending on the vehicle speed, braking force and vehi-
cle environment (temperature, humidity, etc.).

1824-1. Before driving
RC350/RCF_U (OM24636U)
WA R N I N G
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 th e 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 posture 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 righ t 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 co ntrol, but the power assist to these systems
will be lost. This will make it more difficul t 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. 5 2 3
●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. 1 9 9 )
●Do not adjust the positions of the steering wh eel, 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. Ev en 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.

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 pedal 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 acciden t 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 D 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) (RC350)
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 only: Moderate levels of brake pad and disc wear
allow enhanced front braking power. As a re sult, the discs may wear more quickly than
conventional brake discs. Therefore, when replacing the brake pads, Lexus recom-
mends that you also have the thickness 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.
■If a brake pad wear warning message is displayed (RC F)
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.
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 the wear limits of the brake pads and/or those
of the brake discs are exceeded.
