When starting off on an uphill
The hill-start assist control will activate. (  P. 312)■
Driving in the rain ●
Drive carefully when it is ra ining, because visibility will be reduced, the windows may
become fogged-up, and the road will be slippery. ●
Drive carefully when it starts to rain, beca use 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 th e road surface, preventing the steering and
brakes from operating properly. ■
Engine speed while driving
In the following conditions, th e 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 accelerato r pedal is released●
When the brake pedal is depressed 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 mult i-information display while the system is
operating. (  P. 477)■
Restraining sudden start (Drive-Start Control)●
When the following unusual operation is performed, the engine output may be
restrained.
• When the shift lever is shifted from R to D, D to R, N to R, P to D, or P to R (D
includes M) with the accelerator pedal depressed, a warning message appears on
the multi-information display. (  P. 465)
• When the accelerator pedal is depressed t oo much while the vehicle is in reverse.●
While Drive-Start Control is being activated, your vehicle may have trouble escaping
from the mud or fresh snow. In such case, deactivate TRC (  P. 314) to cancel Drive-
Start Control so that the vehicle may beco me able to escape from the mud or fresh
snow. ■

Driving
RC350_RC300 AWD_RC3 00_RC F_U(OM24748U)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
RC350_RC300 AWD_RC3 00_RC F_U(OM24748U)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.

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 visually 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, Lexu s 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. ■
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 ve hicle 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 r acing 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.
