AI-SHIFT

The AI-SHIFT automatically selects

the suitable gear according to driver

operation and driving conditions.

AI-SHIFT automatically operates

when the shift lever is in D or S.

While the engine switch is in

ON and the brake pedal
depressed

, shift the shift lever

while pushing the shift release
button on the shift knob.

Shift the shift lever while

pushing the shift release button

on the shift knob.

Shift the shift lever normally.

When shifting the shift lever
between P and D, make sure that
the vehicle is completely stopped.

: For the vehicle to be able to be

shifted from P, the brake pedal
must be depressed before the
shift release button is pushed. If
the shift release button is pushed
first, the shift lock will not be
released.

■

Shift lock system

The shift lock system is a system to

prevent accidental operation of the

shift lever in starting.

The shift lever can be shifted from P

only when the engine switch is in

ON, the brake pedal is depressed

and the shift release button is

pushed.

■

If the shift lever cannot be

shifted from P

First, check whether the brake pedal

is being depressed.

If the shift lever cannot be shifted

even though the brake pedal is

depressed and the shift release but-

ton is pushed, there may be a prob-

lem with the shift lock system. Have

the vehicle inspected by your Toyota

dealer immediately.

The following steps may be used as

an emergency measure to ensure

that the shift lever can be shifted.
Releasing the shift lock:

Set the parking brake.

Turn the engine switch off.

Depress the brake pedal.

Pry the cover up with a flathead

screwdriver or equivalent tool.

To prevent damage to the cover,

cover the tip of the screwdriver

with a rag.

WARNING

■

When driving on slippery

road surfaces

Do not accelerate or shift gears

suddenly.

Sudden changes in engine brak-

ing may cause the vehicle to spin

or skid, resulting in an accident.

Shifting the shift lever

When the shift lever is in the S
position, the shift lever can be
operated as follows:

Upshifting

Downshifting

The selected shift range, from S1 to
S10 will be displayed on the multi-
information display.
The initial shift range in S mode is
set automatically to 4, 5, 6, 7 or 8
according to vehicle speed.
However, the initial shift range may
be set to 4 if AI-SHIFT has oper-
ated while the shift lever was in the
D position. (

P.207)

■

S mode

●

You can choose from 10 levels of

accelerating force and engine

braking force.

●

A lower shift range will provide

greater accelerating force and

engine braking force than a higher

shift range, and the engine revolu-

tions will also increase.

●

To prevent the engine from over-

revving, upshifting may automati-

cally occur.

●

To protect the automatic transmis-

sion, a function is adopted that

automatically selects a higher shift

WARNING

■

To prevent an accident when

releasing the shift lock

Before pressing the shift lock

override button, make sure to set

the parking brake and depress the

brake pedal.

If the accelerator pedal is acci-

dentally depressed instead of the

brake pedal when the shift lock

override button is pressed and the

shift lever is shifted out of P, the

vehicle may suddenly start, possi-

bly leading to an accident result-

ing in death or serious injury.

is high.

●

When the shift range is 9 or lower,

holding the shift lever toward “+”

sets the shift range to 10.

■

Downshifting restriction warn-

ing buzzer

To help ensure safety and driving

performance, downshifting opera-

tion may sometimes be restricted. In

some circumstances, downshifting

may not be possible even when the

shift lever is operated. (A buzzer will

sound twice.)

■

If the S indicator does not come

on even after shifting the shift

lever to S

This may indicate a malfunction in

the automatic transmission system.

Have the vehicle inspected by your

Toyota dealer immediately.

Use “TOW HAUL” or “TOW+”
mode when pulling a trailer or
hauling a heavy load. Activating

The Automatic High Beam
uses an in-vehicle front
camera to assess the bright-
ness of streetlights, the
lights of vehicles ahead etc.,
and automatically turns the
high beam on or off as nec-
essary.

WARNING

■

Limitations of the Automatic

High Beam

Do not overly rely on the Auto-

matic High Beam. Always drive

safely, taking care to observe your

surroundings and turning the high

beams on or off manually if nec-

essary.

High beam automatic turning

on or off conditions

●

When all of the following condi-

tions are fulfilled, the high beam

will be automatically turned on

(after approximately 1 second):

• Vehicle speed is above approxi-

mately 21 mph (34 km/h) or more.

• The area ahead of the vehicle is

dark.

• There are no vehicles ahead with

headlights or tail lights turned on.

• There are few streetlights on the

road ahead.

●

If any of the following conditions

are fulfilled, the high beam will be

automatically turned off:

• Vehicle speed drops below

approximately 17 mph (27 km/h).

• The area ahead of the vehicle is

not dark.

• Vehicles ahead have headlights or

tail lights turned on.

• There are many streetlights on the

road ahead.

■

Front camera detection infor-

mation

●

The high beam may not be auto-

matically turned off in the following

situations:

• When oncoming vehicles sud-

denly appear from a curve

• When the vehicle is cut in front of

by another vehicle

• When vehicles ahead are hidden

from sight due to repeated curves,

road dividers or roadside trees

• When vehicles ahead appear from

the faraway lane on a wide road

• When vehicles ahead have no

lights

●

The high beam may be turned off

if a vehicle ahead that is using fog

lights without using the headlights

is detected.

●

House lights, street lights, traffic

signals, and illuminated billboards

or signs may cause the high beam

to switch to the low beams, or the

low beams to remain on.

●

The following factors may affect

the amount of time taken to turn

the high beam on or off:

• The brightness of headlights, fog

lights, and tail lights of vehicles

ahead

• The movement and direction of

vehicles ahead

• When a vehicle ahead only has

operational lights on one side

• When a vehicle ahead is a two-

wheeled vehicle

• The condition of the road (gradi-

ent, curve, condition of the road

surface etc.)

• The number of passengers and

amount of luggage

●

The high beam may be turned on

or off when the driver does not

expect it.

●

Bicycles or similar objects may not

be detected.

●

In the situations shown below, the

system may not be able to accu-

rately detect surrounding bright-

ness levels. This may cause the

low beams to remain on or the

high beams to cause problems for

pedestrians, vehicles ahead or

other parties. In these cases,

manually switch between the high

and low beams.

• In bad weather (rain, snow, fog,

222

4-3. Operating the lights and wipers

sandstorms, etc.)

• The windshield is obscured by

fog, mist, ice, dirt, etc.

• The windshield is cracked or dam-

aged

• The front camera is deformed or

dirty

• When the temperature of the front

camera is extremely high

• Surrounding brightness levels are

equal to those of headlights, tail

lights or fog lights

• When headlights or tail lights of

vehicles ahead are turned off,

dirty, changing color, or not aimed

properly

• When the vehicle is hit by water,

snow, dust, etc. from a preceding

vehicle

• When driving through an area of

intermittently changing brightness

and darkness

• When frequently and repeatedly

driving ascending/descending

roads, or roads with rough, bumpy

or uneven surfaces (such as

stone-paved roads, gravel roads,

etc.)

• When frequently and repeatedly

taking curves or driving on a wind-

ing road

• There is a highly reflective object

ahead of the vehicle, such as a

sign or mirror

• The back of a vehicle ahead is

highly reflective, such as a con-

tainer on a truck

• The vehicle’s headlights are dam-

aged or dirty, or are not aimed

properly

• The vehicle is listing or titling due

to a flat tire, a trailer being towed,

etc.

• The high beam and low beam are

repeatedly being switched

between in an abnormal manner

• The driver believes that the high

beam may be causing problems

or distress to other drivers or

pedestrians nearby

temporarily lowered.

Turn the engine switch off while

the following conditions are met.
