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.

WARNING ■
Handling the radar sensor
Blind Spot Monitor sensors ar e installed behind the left and right sides of the rear
bumper respectively. Observe the following to ensure the Blind Spot Monitor can
function correctly.
●
Do not subject a sensor or its surrounding area on the rear bumper to a strong
impact.
If a sensor is moved even slightly off po sition, the system may malfunction and vehi-
cles may not be detected correctly.
In the following situations , have your vehicle inspected by your Lexus dealer.
• A sensor or its surrounding area is subject to a strong impact.
• If the surrounding area of a sensor is sc ratched or dented, or part of them has
become disconnected. ●
Do not disassemble the sensor. ●
Do not attach stickers to the sensor or surrounding area on the rear bumper.●
Do not modify the sensor or surro unding area on the rear bumper.●
Do not paint the rear bumper any colo r other than an official Lexus color.●
Keep the sensors and the surrounding areas
on the rear bumper clean at all times.
If a sensor or its surrounding area on the rear
bumper is dirty or covered with snow, the
Blind Spot Monitor may not operate and a
warning message (  P. 471) will be displayed.
In this situation, clear off the dirt or snow and
drive the vehicle with the operation condi-
tions of the BSM function (  P. 295) satisfied

WARNING ■
Cautions regarding the use of the function
The driver is solely responsible for safe driving. Always drive safely, taking care to
observe your surroundings.
The BSM function is a supplementary function which alerts the driver that a vehicle is in
a blind spot of the outside rear view mirrors or is approaching rapidly from behind into
a blind spot. Do not overly rely on the BSM function. As the function cannot judge if it is
safe to change lanes, over reliance could lead to an accident resulting in death or seri-
ous injury.
As the system may not function correctly under certain conditions, the driver’s own
visual confirmation of safety is necessary. 1
