4-5. Using the driving support systems

Example:

The RCTA function is operational when

The RCTA function operates when all of the

following conditions are met:

The RCTA function is on.

The shift position is in R.

The vehicle speed is less than approxi-

mately 8 km/h (5 mph).

The approaching vehicle speed is

between approximately 8 km/h (5 mph)

and 28 km/h (18 mph).

Conditions under which the RCTA

function will not detect a vehicle

The RCTA function is not designed to

detect the following types of vehicles

and/or objects:

Vehicles approaching from directly

behind

Vehicles backing up in a parking space

next to your vehicle

Vehicles that the sensors cannot detect

due to obstructions

Guardrails, walls, signs, parked vehicles
and similar stationary objects

Small motorcycles, bicycles, pedestrians,
etc.

Vehicles moving away from your vehicle

Vehicles approaching from the parking
spaces next to your vehicle

: Depending on the conditions, detection

of a vehicle and/or object may occur.

Conditions under which the RCTA

function may not function correctly

The RCTA function may not detect vehi-

cles correctly in the following situations:

• When the sensor is misaligned due to a

strong impact to the sensor or its sur-

rounding area

• When mud, snow, ice, a sticker, etc. is

covering the sensor or surrounding area

on the rear bumper

• When driving on a road surface that is

wet with standing water during bad

weather, such as heavy rain, snow, or fog

• When multiple vehicles are approaching

with only a small gap between each vehi-

cle

• When a vehicle is approaching at high

speed

• When a towing eyelet is installed to the

rear of the vehicle.

• When backing up on a slope with a sharp

change in grade

• When backing out of a shallow angle

parking spot

• Immediately after the RCTA function is

turned on

• Immediately after the engine is started

with the RCTA function on

• When the sensors cannot detect a vehi-

cle due to obstructions

Instances of the RCTA function unneces-

sarily detecting a vehicle and/or object

may increase in the following situations:

• When a vehicle passes by the side of your

vehicle

• When the parking space faces a street

and vehicles are being driven on the

street

• When the distance between your vehicle

and metal objects, such as a guardrail,

wall, sign, or parked vehicle, which may

reflect electrical waves toward the rear of

the vehicle, is short

• When a towing eyelet is installed to the

rear of the vehicle.

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 RCTA function is only a supplemen-

tary function which alerts the driver that a

vehicle is approaching from the right or

left at the rear of the vehicle. As the

RCTA function may not function cor-

rectly under certain conditions, the

driver’s own visual confirmation of safety

is necessary. Over reliance on this func-

tion may lead to an accident resulting

death or serious injury.

generates braking force correspond-
ing to the brake operation

ABS (Anti-lock Brake System)

Helps to prevent wheel lock when the
brakes are applied suddenly, or if the
brakes are applied while driving on a
slippery road surface

Brake assist

Generates an increased level of brak-
ing force after the brake pedal is
depressed when the system detects a
panic stop situation

VSC (Vehicle Stability Control)

Helps the driver to control skidding
when swerving suddenly or turning on
slippery road surfaces

TRC (Traction Control)

Helps to maintain drive power and
prevent the drive wheels from spinning

Exhaust Gas Filter system

The Exhaust Gas Filter system is
designed to collect particulate mat-
ter in the exhaust gases using an
exhaust gas filter installed to the
exhaust pipes.

NOTICE

To prevent the Exhaust Gas Filter

system from failing

Do not use fuel other that the specified

type

Do not modify the exhaust pipes

Driving assist systems

to ensure proper operation of the

brakes, TRC and VSC.

Hill- start assist control does not

operate effectively when

Do not overly rely on hill-start assist

control. Hill-start assist control may

not operate effectively on steep

inclines and roads covered with ice.

Unlike the parking brake, hill-start

assist control is not intended to hold

the vehicle stationary for an extended

period of time. Do not attempt to use

hill-start assist control to hold the vehi-

cle on an incline, as doing so may lead

to an accident.

When the TRC/ABS/VSC is acti-

vated

The slip indicator light flashes. Always

drive carefully. Reckless driving may

cause an accident. Exercise particular

care when the indicator light flashes.

When the TRC/VSC systems are

tions. As these are the systems to help

ensure vehicle stability and driving force,

do not turn the TRC/VSC systems off

unless necessary.

Replacing tires

Make sure that all tires are of the speci-

fied size, brand, tread pattern and total

load capacity. In addition, make sure that

the tires are inflated to the recom-

mended tire inflation pressure level.
The ABS, TRC and VSC systems will not

function correctly if different tires are

installed on the vehicle.
Contact any authorized Lexus retailer or

Lexus authorized repairer, or any reli-

able repairer for further information

g

Perform the following according to the
driving conditions:



Do not try to forcibly open a door or
a side window, or move wipers that
are frozen. Pour warm water over
the frozen area to melt the ice, and
then wipe away the water immedi-
ately to prevent it from freezing.



When the outside door handle is
frozen, unlock the doors using the
wireless remote control. If the out-
side door handles remain retracted
and do not move even if the doors
are unlocked using the wireless
remote control, pour warm water
over the frozen area to melt the ice
and wipe away the water immedi-
ately to prevent it from freezing. The
outside door handle may not retract
due to ice, however, the outside
door handle will return to the nor-
mal position after the ice melts.



To ensure proper operation of the
climate control system fan, remove
any snow that has accumulated on
the air inlet vents in front of the

windshield.



Check for and remove any excess
ice or snow that may have accumu-
lated on the exterior lights, soft top
roof, chassis, around the tires or on
the brakes.
