Operating conditions of

hill-start assist control

When the following four conditions

are met, the hill-start assist control

will operate:

●

The shift lever is in a position

other than R when starting off for-

ward on an upward incline, or the

shift lever is in R when starting off

backward on an upward incline.

●

The vehicle is stopped

●

The accelerator pedal is not

depressed

●

The parking brake is not engaged

●

The engine switch is turned to ON

■

Automatic system cancelation

of hill-start assist control

The hill-start assist control will turn

off in any of the following situations:

●

The shift lever is shifted to R when

starting off forward on an upward

incline, or the shift lever is shifted

to other than R when starting off

backward on an upward incline.

●

The accelerator pedal is

depressed

●

The parking brake is engaged

●

A maximum of 2 seconds have

elapsed after the brake pedal is

released

●

The engine switch is turned to

OFF

■

Sounds and vibrations caused

by the ABS, brake assist, VSC,

TRAC and hill-start assist con-

trol systems

●

A sound may be heard from the

engine compartment when the

brake pedal is depressed repeat-

edly, when the engine is started or

just after the vehicle begins to

move. This sound does not indi-

cate that a malfunction has

occurred in any of these systems.

●

Any of the following conditions

may occur when the above sys-

tems are operating. None of these

indicates that a malfunction has

occurred.

• Vibrations may be felt through the

vehicle body and steering.

• A motor sound may be heard also

after the vehicle comes to a stop.

• The brake pedal may pulsate

slightly after the ABS is activated.

off, the TRAC will turn on when

vehicle speed increases

If both the TRAC and VSC sys-

tems are turned off, automatic

re-enabling will not occur when

vehicle speed increases.

■

Reduced effectiveness of the

EPS system

The effectiveness of the EPS sys-

tem is reduced to prevent the sys-

tem from overheating when there is

frequent steering input over an

extended period of time. The steer-

ing wheel may feel heavy as a

result. Should this occur, refrain

from excessive steering input or

stop the vehicle and turn the engine

off. The EPS system should return

to normal within 10 minutes.

ing

WARNING

●

Unlike the parking brake,

hill-start assist control is not

intended to hold the vehicle sta-

tionary 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 acci-

dent.

■

When the TRAC/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 TRAC/VSC systems

are turned off

Be especially careful and drive at

a speed appropriate to the road

conditions. As these are the sys-

tems to help ensure vehicle stabil-

ity and driving force, do not turn

the TRAC/VSC systems off

unless necessary.

■

Expert mode precautions

●

Do not use on public roads.

●

Use only when the road condi-

tions and safely of the surround-

ing area can be ensured.

●

Proper use of expert mode

requires a professional level of

driving skill. When using expert

mode, always check the road

conditions and surrounding area

and drive more carefully than

usual.

■

Replacing tires

Make sure that all tires are of the

specified size, brand, tread pat-

tern 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 sys-

tems will not function correctly if

different tires are installed on the

vehicle.

Contact your Toyota dealer for fur-

ther information when replacing

tires or wheels.

■

Handling of tires and the sus-

pension

Using tires with any kind of prob-

lem or modifying the suspension

will affect the driving assist sys-

tems, and may cause a system to

malfunction.

■

Active Torque Split AWD sys-

tem

●

The Active Torque Split AWD

system is designed to ensure

driving stability on general

roads and not for off-road driv-

ing such as for rallying. Do not

subject the system to extreme

driving conditions.

●

Drive carefully on slippery road

surfaces.

■

Secondary Collision Brake

Do not overly rely on the Second-

ary Collision 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.

4-6. Driving tips

ing

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 wind-
shield.



Check for and remove any
excess ice or snow that may
have accumulated 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.

Accelerate the vehicle slowly,
keep a safe distance between
you and the vehicle ahead, and
drive at a reduced speed suit-
able to road conditions.
