4-5. Using the driving support systems
This mode employs a radar sensor to detect the presence of vehicles up to approx-
imately 100 m (328 ft.) ahead, determines the current vehicle-to-vehicle following
distance, and operates to maintain a suitable following distance from the vehicle
ahead.
Note that vehicle-to-vehicle distance will clos e in when traveling on long downhill slopes.
Example of constant speed cruising
When there are no vehicles ahead
The vehicle travels at the speed set by the driver. The desired vehicle-to-vehicle distance
can also be set by operating the vehicle-to-vehicle distance switch.
Example of deceleration cruising and follow-up cruising
When a preceding vehicle driving slower than the set speed appears
When a vehicle is detected running ahead of you, the system automatically decelerates
your vehicle. When a greater reduction in ve hicle speed is necessary, the system applies
the brakes (the stop lights will come on at th is time). The system will respond to changes in
the speed of the vehicle ahead in order to maintain the vehicle-to-vehicle distance set by
the driver. Approach warning warns you when the system cannot decelerate sufficiently to
prevent your vehicle from closing in on the vehicle ahead.
When the vehicle ahead of you stops, your vehi cle will also stop (vehicle is stopped by sys-
tem control). After the vehicle ahead starts off, pressing the +/RES switch or depressing the
accelerator pedal will resume follow-up cruising.

4-5. Using the driving support systems
DrivingAfter the vehicle ahead of you starts
off, press the +/RES switch.
Your vehicle will also resume follow-up
cruising if the accelerator pedal is
depressed after the vehicle ahead of
you starts off.
1 Pressing the cancel switch cancels
the speed control.
The speed control is also canceled when
the brake pedal is depressed.
(When the vehicle has been stopped by
system control, depressing the brake pedal
does not cancel the setting.)
2 Pressing the +/RES switch resumes
the cruise control and returns vehi-
cle speed to the set speed.
However, when a vehicle ahead is not
detected, cruise control does not resume
when the vehicle speed is approximately
40 km/h (25 mph) or less.
When your vehicle is too close to a
vehicle ahead, and sufficient automatic
deceleration via the cruise control is
not possible, the display will flash and
the buzzer will sound to alert the driver.
An example of this would be if another
driver cuts in front of you while you are
following a vehicle. Depress the brake
pedal to ensure an appropriate vehi-
cle-to-vehicle distance.

●Vehicle speed is at or above approxi-
mately 50 km/h (30 mph). However, when a preceding vehicle is detected, the dynamic radar cruise con-
trol with full-speed range can be set even if the vehicle speed is below approxi-mately 50 km/h (30 mph).
■Accelerating after setting the vehicle
speed
The vehicle can accelerate by operating the
accelerator pedal. After accelerating, the set speed resumes. Ho wever, during vehi- cle-to-vehicle distance control mode, the
vehicle speed may decrease below the set speed in order to maintain the distance to the preceding vehicle.
■When the vehicle stops while follow-up
cruising
●Pressing the +/RES switch while the vehi-
cle ahead stops will resume follow-up cruising if the vehicle ahead starts off within approximately 3 seconds after the
switch is pressed.
●If the vehicle ahead starts off within 3 sec-
onds after your vehicle stops, follow-up cruising will be resumed.
■Automatic cancelation of vehicle-to-
vehicle distance control mode
Vehicle-to-vehicle distance control mode is
automatically canceled in the following situ- ations.
●Actual vehicle speed falls below approxi-mately 40 km/h (25 mph) when there are no vehicles ahead.
●The preceding vehicle leaves the lane when your vehicle is following at a vehicle
speed below approximately 40 km/h (25 mph). Otherwise, the sensor can not properly detect the vehicle. (“CRUISE
NOT AVAILABLE No Preceding Vehi- cles” is displayed on the multi-information display.)
●VSC is activated.
●TRC is activated for a period of time.
●When the VSC or TRC system is turned
off.
●When snow mode is set.
●The sensor cannot detect correctly
because it is covered in some way.
●Pre-collision brakin g is activated.

●The following are detected when the vehicle has been stopped by system con-trol:
• The driver is not wearing a seat belt. • The driver’s door is opened.• The vehicle has been stopped for about 3
minutes
If vehicle-to-vehicle distance control mode
is automatically canceled for any other rea-
son, there may be a malfunction in the sys-
tem. Contact any authorized Lexus retailer
or Lexus authorized repairer, or any reliable
repairer.
■Automatic cancelation of constant speed control mode
Constant speed control mode is automati- cally canceled in the following situations:

4-5. Using the driving support systems
■ECB (Electronically Controlled
Brake System)
The electronically controlled system
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
■Secondary Collision Brake (if
equipped)
When the airbag sensor detects a colli-
sion, the brakes and brake lights are
automatically controlled to reduce the
vehicle speed and that helps reduce
the possibility of further damage due to
a secondary collision.
■TRC (Traction Control)
Helps to maintain drive power and pre-
vent the drive wheels from spinning
when starting the vehicle or accelerat-
ing on slippery roads
■Hill-start assist control
Helps to reduce the backward move-
ment of the vehicle when starting on an
uphill
■VGRS (Variable Gear Ratio Steer-
ing) (if equipped)
Adjusts the front wheel turning angle in
accordance with the vehicle speed and
steering wheel movement
■DRS (Dynamic Rear Steering) (if
equipped)
Contributes to the turning characteris-
tics and responsiveness of the vehicle
by slightly adjusting the rear wheel
angle of the vehicle in accordance with
steering wheel movement.
■EPS (Electric Power Steering)
Employs an electric motor to reduce
the amount of effort needed to turn the
steering wheel
■AVS (Adaptive Variable Suspen-
sion System)
By independently controlling the
damping force of the shock absorbers
for each of the 4 wheels according to
Driving assist systems
To keep driving safety and perfor-
mance, the following systems oper-
ate automatically in response to
various driving situations. Be aware,
however, that these systems are
supplementary and should not be
relied upon too heavily when oper-
ating the vehicle.

In this event, the steering wheel may move from its straight forward position, but it will
return when the system restarts.
●When the steering wheel is operated for
an extended period of time while the vehicle is stopped or is moving very slowly (on vehicles with LDH, DRS is dis-
abled together with VGRS)
●When the steering wheel has been held
fully to the left or right
The center position of the steering wheel
may change when VGRS is disabled. How- ever, the position will return to normal after VGRS is reactivated.
■When the 12-volt battery is discon-
nected (vehicles with VGRS)
The steering wheel may move from its
straight forward position, but this will be corrected automatically when driving.
■Sounds and vibrations caused by the ABS, brake assist, TRC, VSC, hill-start
assist control and VGRS systems
●A sound may be heard from the engine
compartment when the brake pedal is depressed repeatedly, when the engine is started or just after the
vehicle begins to move. This sound does not indicate that a malfunction has occurred in any of these systems.
●Any of the following conditions may
occur when the above systems are oper- ating. None of these indicates that a mal-function has occurred.
• Vibrations may be felt through the vehicle body and steering.• A motor sound may be heard after the
vehicle comes to a stop.

4-5. Using the driving support systems
WARNING
■Stopping distance when the ABS is operating may exceed that of normal conditions
The ABS is not designed to shorten the vehicle’s stopping distance. Always main-
tain a safe distance from the vehicle in front of you, especially in the following situations:
●When driving on dirt, gravel or snow-
covered roads
●When driving with tire chains
●When driving over bumps in the road
●When driving over roads with potholes or uneven surfaces
■TRC/VSC may not operate effec-tively when
Directional control and power may not be achievable while driving on slippery
road surfaces, even if the TRC/VSC sys- tem is operating.
Drive the vehicle carefully in conditions where stability and power may be lost.
■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/VSC/ABS 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 turned off
Be especially careful and drive at a speed appropriate to the road conditions. As
these are the systems to help ensure vehicle stability and dr iving force, do not turn the TRC/VSC systems off unless
necessary.
■Secondary Collision Brake
Do not overly rely on the Secondary Col-
lision Brake. This system is designed to help reduce the possibility of further damage due to a secondary collision,
however, that effect changes according to various conditions. Overly relying on the system may result in death or serious
injury.
■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 reliable
repairer for further information when replacing tires or wheels.
■Handling of tires and the suspension
Using tires with any kind of problem or modifying the suspension will affect the driving assist systems, and may cause a
system to malfunction.

4-6. Driving tips
Control and maintain the vehicle at a
constant speed. Before stopping at a
toll booth or similar, allow plenty of
time to release the accelerator and
gently apply the brakes. A greater
amount of electrical energy can be
regenerated when slowing down.
Use the air conditioning only when
necessary. Doing so can help reduce
excessive gasoline consumption.
In summer: When the ambient tem-
perature is high, use the recirculated
air mode. Doing so will help to reduce
the burden on the air conditioning sys-
tem and reduce fuel consumption as
well.
In winter: Because the gasoline engine
will not automatically cut out until it and
the interior of the vehicle are warm, it
will consume fuel. Also, fuel consump-
tion can be improved by avoiding over-
use of the heater.
Make sure to check the tire inflation
pressure frequently. Improper tire infla-
tion pressure can cause poor fuel
economy.
Also, as snow tires can cause large
amounts of friction, their use on dry
roads can lead to poor fuel economy.
Use tires that are appropriate for the
season.
Carrying heavy luggage will lead to
poor fuel economy. Avoid carrying
unnecessary luggage. Installing a large
roof rack will also cause poor fuel
economy.
Since the gasoline engine starts up and
cuts out automatically when cold,
warming up the engine is unnecessary.
Moreover, frequently driving short dis-
tances will cause the engine to repeat-
edly warm up, which can lead to excess
fuel consumption.

6-1. Maintenance and care
2Remove the filter.
3 Remove dust using a vacuum
cleaner etc. to clean the filter.
Also, remove dust on the grille as well as on the filter using a vacuum cleaner.
4 Install the filter in its original posi-
tion, and then install the grille.
5 Start the hybrid system and check
that the warning message on the
multi-information display disap-
pears.
It may take several minutes before the warning message disappears.
■Cleaning the air intake vents and filters
●Dust on the air intake vents or filters may interferes cooling of the hybrid battery (traction battery) and results in poor fuel
consumption. Clean the air intake vents and filters periodically.
●If continuing to drive the vehicle with “Maintenance required for Traction bat-tery cooling parts See owner’s manual”
shown on the multi-information display, the hybrid battery (traction battery) input and output may be restricted, leading to a
reduction in hybrid battery (traction bat- tery) output and a malfunction. It may cause poor fuel consumption or a mal-
function. If the warning message is shown, contact any authorized Lexus retailer or Lexus authorized repairer, or any reliable
repairer or clean the air intake vents and filters immediately.
●Improper handling may result in damage to the grille or filters. If you have any con-cerns about cleaning the filters, contact
any authorized Lexus retailer or Lexus authorized repairer, or any reliable repairer.
●If the warning message on the multi-infor-mation display does not disappear after
cleaning the filters, have the vehicle inspected by any authorized Lexus retailer or Lexus authorized repairer, or
any reliable repairer.
●Timing of cleaning filters differs depend-
ing on the use environment of the vehicle.
NOTICE
■When cleaning the air intake vents
and filters
Observe the following precautions. Fail-
ure to do so may cause damage to the vehicle.
●When removing the air intake vent grille, make sure to turn the power
switch off to stop the hybrid system.
●Do not use water or other liquid to clean the air intake vents or filters.
●Do not allow water or foreign matter to enter the air intake vent when the grille
is removed.
●Carefully handle th e removed filters not to damage.If the filter is damaged, have it replaced
with a new filter by any authorized Lexus retailer or Lexus authorized repairer, or any reliable repairer.
