Automatic reactivation of TRAC and VSC systems
After turning the TRAC and VSC systems off, the systems will be automati-
cally re-enabled in the following situations:

●

When the power switch is turned off

●

If only the TRAC system is turned off, the TRAC will turn on when vehicle
speed increases
If both the TRAC and VSC systems are turned off, automatic re-enabling will
not occur when vehicle speed increases

■

Secondary Collision Brake operating conditions
The vehicle speed is approximately 6 mph (10 km/h) or more and the airbag
sensor  detects  a  collision.  (The  Secondary  Collision  Brake  will  not  operate
when the vehicle speed is below approximately 6 mph [10km/h].)

■

Secondary Collision Brake automatic cancellation
The Secondary Collision Brake is automatically canceled in the following situ-
ations:

●

The vehicle speed drops below approximately 6 mph (10 km/h)

●

A certain amount of time elapses during operation

●

The accelerator pedal is depressed a large amount

■

Reduced effectiveness of the EPS system
The effectiveness of the EPS system is reduced to prevent the system from
overheating when there is frequent steering input over an extended period of
time. The steering wheel may feel heavy as a result. Should this 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.

4-5. Using the driving support systems

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 distance. Always
maintain 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

■

TRAC/VSC may not operate effectively when
Directional control and power may not be achievable while driving on slip-
pery road surfaces, even if the TRAC/VSC system 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 vehicle on an incline, as doing so may
lead to an accident.

■

When the TRAC/ABS/VSC is activated
The slip indicator light flashes. Always drive carefully. Reckless driving may
cause an accident. Exercise particular care when the indicator light flashes.

■

When the TRAC/VSC systems are turned off
Be  especially  careful  and  drive  at  a  speed  appropriate  to  the  road  condi-
tions. As these are the systems to help ensure vehicle stability and driving
force, do not turn the TRAC/VSC systems off unless necessary.

■

Secondary Collision Brake
Do  not  overly  rely  on  the  Secondary  Collision  Brake.  This  system  is
designed to help reduce the possibility of further damage due to a second-
ary collision, however, that effect changes according to various conditions.
Overly relying on the system may result in death or serious injury.

WARNING

■

Replacing tires
Make sure that all tires are of the specified size, brand, tread pattern and
total load capacity. In addition, make sure that the tires are inflated to the
recommended tire inflation pressure level.
The ABS, TRAC and VSC systems will not function correctly if different tires
are installed on the vehicle.
Contact  your Toyota  dealer  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

◆

Using Eco drive mode

When using Eco drive mode, the torque corresponding to the accel-
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, improving
the fuel economy. (

P. 315)

◆

Use of Hybrid System Indicator

The Eco-friendly driving is possible by keeping the needle of Hybrid
System Indicator within Eco area. (

P. 94)

◆

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. When using
the N, there is no positive effect on fuel consumption. In the N, the
gasoline engine operates but electricity cannot be generated. Also,
when  using  the  air  conditioning  system,  etc.,  the  hybrid  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) without
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:

◆

When braking

Make sure to operate the brakes gently and in a timely manner. A
greater amount of electrical energy can be regenerated when slow-
ing down.

◆

Delays

Repeated  acceleration  and  deceleration,  as  well  as  long  waits  at
traffic  lights,  will  lead  to  bad  fuel  economy.  Check  traffic  reports
before leaving and avoid delays as much as possible. When driving
in a traffic jam, gently release the brake pedal to allow the vehicle to
move  forward  slightly  while  avoiding  overuse  of  the  accelerator
pedal. Doing so can help control excessive gasoline consumption.

◆

Highway driving

Control and maintain the vehicle at a constant speed. Before stop-
ping  at  a  toll  booth  or  similar,  allow  plenty  of  time  to  release  the
accelerator and gently apply the brakes. A greater amount of elec-
trical energy can be regenerated when slowing down.

◆

Air conditioning

Use  the  air  conditioning  only when necessary.  Doing  so  can  help
reduce excessive gasoline consumption.
In summer: When the ambient temperature is high, use the recircu-
lated air mode. Doing so will help to reduce the burden on the air
conditioning system 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 consumption can be improved by avoiding overuse of the
heater.

◆

Checking tire inflation pressure

Make sure to check the tire inflation pressure frequently. Improper
tire inflation 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 appro-
priate for the season.

326

◆

Luggage

Carrying heavy luggage will lead to poor fuel economy. Avoid carry-
ing unnecessary luggage. Installing a large roof rack will also cause
poor fuel economy.

◆

Warming up before driving

Since  the  gasoline  engine  starts  up  and  cuts  out  automatically
when cold, warming up the engine is unnecessary. Moreover, fre-
quently driving short distances will cause the engine to repeatedly
warm up, which can lead to excess fuel consumption.

● Use  fluids  that  are appropriate  to  the  prevailing outside  tempera-

tures. 

• Engine oil
• Engine/power control unit coolant
• Washer fluid

● Have a service technician inspect the condition of the 12-volt bat-

tery.

● Have the vehicle fitted with four snow tires or purchase a set of tire

chains for the front tires.

*

Ensure  that  all  tires  are  the  specified  size  and  brand,  and  that  chains
match the size of the tires.

*

: Tire chains cannot be mounted on vehicles with 18 and 19-inch tires.

Perform the following according to the driving conditions: 
● Do not try to forcibly open a window or move a wiper that is frozen.

Pour warm water over the frozen area to melt the ice. Wipe away
the water immediately to prevent it from freezing. 

● 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 accu-

mulated  on  the  exterior  lights,  vehicle’s  roof,  chassis,  around  the
tires or on the brakes.

● Remove any snow or mud from the bottom of your shoes before

getting in the vehicle.

Winter driving tips

Carry  out  the  necessary  preparations  and  inspections  before
driving the vehicle in winter. Always drive the vehicle in a man-
ner appropriate to the prevailing weather conditions. 

Preparation for winter

Before driving the vehicle

328

4-6. Driving tips

Accelerate the vehicle slowly, keep a safe distance between you and
the vehicle ahead, and drive at a reduced speed suitable to road con-
ditions. 

● Park the vehicle and move the shift lever to P without setting the

parking brake. The parking brake may freeze up, preventing it from
being released. If the vehicle is parked without setting the parking
brake, make sure to block the wheels.
Failure to do so may be dangerous because it may cause the vehi-
cle to move unexpectedly, possibly leading to an accident.

● If the vehicle is parked without setting the parking brake, confirm

that the shift lever cannot be moved out of P

*

.

*

: The shift lever will be locked if it is attempted to be shifted from P to any

other position without depressing the brake pedal. If the shift lever can be
shifted from P, there may be a problem with the shift lock system. Have the
vehicle inspected by your Toyota dealer immediately.

Vehicles with 17-inch tires

Use the correct tire chain size when mounting the snow chains. 
Chain size is regulated for each tire size.
