GPF (Gasoline Par ticulate Filter) system
■If “Exhaust filter full. See owner’s manual.” is shown on the multi-infor-
mation display
● The message may be displayed while high load driving with particulate mat-
ter accumulating.
● Hybrid system output (engine speed) is restricted when a certain amount of
particulate matter accumulates, however, it is possible to driv e the vehicle
unless the malfunction indicator lamp comes on.
● Particulate matter can accumulate more quickly if the vehicle is frequently
driven short trips or at low s peeds, or if the hybrid system is regularly started
in an extremely cold environment. Excessive accumulation of par ticulate
matter can be prevented by periodically driving long distances continuously
with intermittent releasing of the accelerator pedal, such as w hen driving on
highways and freeways.
■ If the malfunction indicator lamp comes on or “Engine Maintenance
Required. Visit Your Dealer.” is shown on the multi-information display
The amount of accumulated particulate matter has exceeded a cer tain level.
Have the vehicle inspected by any authorized Toyota retailer or Toyota autho-
rized repairer, or any reli able repairer immediately.
The GPF system collects particulate matter in the exhaust gas
by using an exhaust gas filter.
The system will operate to regenerate the filter automatically,
depending on the vehicle conditions.
NOTICE
■ To prevent the GPF system from not operating properly
● Do not use fuel other than the specified type
● Do not modify the exhaust pipes

Driving assist systems
◆ECB (Electronically Controlled Brake System)
The electronically controlled system generates braking force co rre-
sponding to the brake operation
◆ABS (Anti-lock Brake System)
Helps to prevent wheel lock when the brakes are applied suddenl y,
or if the brakes are applied while driving on a slippery road s urface
◆Brake assist
Generates an increased level of braking force after the brake p edal
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
To keep driving safety and performance, the following systems
operate automatically in response to various driving situations .
Be aware, however, that these systems are supplementary and
should not be relied upon too heavily when operating the vehi-
cle.

road surfaces by controlling steering performance.
◆TRC (Traction Control)
Helps to maintain drive power and prevent the drive wheels from
spinning when starting the vehicle or accelerating on slippery roads
◆Active Cornering Assist (ACA)
Helps to prevent the vehicle from drifting to the outer side by per-
forming inner wheel brake control when attempting to accelerate
while turning.
◆Hill-start assist control
Helps to reduce the backward movement of the vehicle when start -
ing on an uphill
◆EPS (Electric Power Steering)
Employs an electric motor to reduce the amount of effort needed to
turn the steering wheel

■ Active Cornering Assist operation sounds and vibrations
When the Active Cornering Assi st is operated, operation sounds and vibra-
tions may be generated from the brake system, but this is not a malfunction.
■ EPS operation sound
When the steering wheel is operated, a motor sound (whirring so und) may be
heard. This does not indicate a malfunction.
■ Automatic reactivation of TRC, Trailer Sway Control and VSC systems
After turning the TRC, Trailer Sway Control and VSC systems off , the sys-
tems will be automatically re- enabled in the following situations:
● When the power switch is turned off
● If only the TRC system is turned off, the TRC will turn on when vehicle
speed increases
If both the TRC and VSC systems are turned off, automatic re-en abling will
not occur when vehicle speed increases.
■ Operating conditions of Active Cornering Assist
The system operates when the following occurs:
● TRC/VSC can operate
● The driver is attempting to accelerate while turning
● The system detects that the vehicle is drifting to the outer side
● The brake pedal is released
■ Reduced effectiveness of the EPS system
The effectiveness of the EPS system is reduced to prevent the s ystem from
overheating when there is frequent steering input over an exten ded period of
time. The steering wheel may feel heavy as a result. Should thi s occur, refrain
from excessive steering input or stop the vehicle and turn the hybrid system
off. The EPS system should return to normal within 10 minutes.
■ Operating conditions of hill-start assist control

WARNING
■The ABS does not operate effectively when
● The limits of tire gripping performance have been exceeded (such as
excessively worn tires on a snow covered road).
● The vehicle hydroplanes while driving at high speed on wet or slick roads.
■ Stopping distance when the ABS is operating may exceed that of nor-
mal conditions
The ABS is not designed to shorten the vehicle’s stopping dista nce. Always
maintain a safe distance from the vehicle in front of you, espe cially 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 effectively when
Directional control and power may not be achievable while drivi ng on slip-
pery road surfaces, even if the TRC/VSC system is operating.
Drive the vehicle carefully in conditions where stability and p ower may be
lost.
■ Active Cornering Assist does not operate effectively when
● Do not overly rely on Active Cornering Assist. Active Cornering A ss i st m a y

WARNING
■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 wit h 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 attem pt to use
hill-start assist control to hold the vehicle on an incline, as doing so may
lead to an accident.
■ When the TRC/ABS/VSC/Trailer Sway Control is activated
The slip indicator light flashes. Always drive carefully. Reckl ess driving may
cause an accident. Exercise particular care when the indicator light flashes.
■ When the TRC/VSC/Trailer Sway Control systems are turned off
Be especially careful and drive at a speed appropriate to the r oad condi-
tions. As these are the systems to help ensure vehicle stabilit y and driving
force, do not turn the TRC/VSC/Trailer Sway Control systems off unless
necessary.
Trailer Sway Control is part of the VSC system and will not ope rate if VSC is
turned off or experiences a malfunction.
■ Replacing tires
Make sure that all tires are of the specified size, brand, trea d pattern and
total load capacity. In addition, make sure that the tires are inflated to the
recommended tire inflation pressure level.
The ABS, TRC, Trailer Sway Control and VSC systems will not fun ction cor-
rectly if different tires are installed on the vehicle.
Contact any authorized Toyota retailer or Toyota authorized rep airer, or any
reliable repairer for further information when replacing tires or wheels.

WARNING
■Handling of tires and the suspension
Using tires with any kind of problem or modifying the suspensio n will affect
the driving assist systems, and may cause a system to malfuncti on.
■ Trailer Sway Control precaution
The Trailer Sway Control system is not able to reduce trailer s way in all situ-
ations.
Depending on many factors such as the conditions of the vehicle , trailer,
road surface and driving environm ent, the Trailer Sway Control system may
not be effective. Refer to your trailer owner’s manual for info rmation on how
to tow your trailer properly.
■ If trailer sway occurs
Observe the following precautions.
Failing to do so may cause death or serious injury.
● Firmly grip the steering wheel. Steer straight ahead.
Do not try to control trailer sway by turning the steering whee l.
● Begin releasing the accelerator pedal immediately but very gradually to
reduce speed.
Do not increase speed. Do not apply vehicle brakes.
If you make no extreme correction with the steering or brakes, your vehicle
and trailer should stabilize. ( P. 299)

Hybrid Electric Vehicle driving tips
◆Using Eco drive mode
When using Eco drive mode, the torque corresponding to the acce l-
erator pedal depression amount can be generated more smoothly
than it is in normal conditions. In addition, the operation of the air
conditioning system (heating/cooling) will be minimized, improv ing
the fuel economy. ( P. 4 3 0 )
◆Use of Hybrid System Indicator
The Eco-friendly driving is possible by keeping the Hybrid Syst em
Indicator within Eco area. ( P. 166)
◆Shift lever operation
Shift the shift lever to D when stopped at a traffic light, or driving in
heavy traffic, etc. Shift the shift lever to P when parking. Wh en
using the N, there is no positive effect on fuel consumption. I n the
N, the gasoline engine operates but electricity cannot be gener -
ated. Also, when using the air conditioning system, etc., the h ybrid
battery (traction battery) power is consumed.
◆Accelerator pedal/brake pedal operation
● Drive your vehicle smoothly. Avoid abrupt acceleration and
deceleration. Gradual acceleration and deceleration will make
more effective use of the electric motor (traction motor) witho ut
having to use gasoline engine power.
● Avoid repeated acceleration. Repeated acceleration consumes
hybrid battery (traction battery) power, resulting in poor fuel con-
sumption. Battery power can be restored by driving with the
accelerator pedal slightly released.
For economical and ecological driving, pay attention to the fol -
lowing points:
