riv

ing

This mode employs a radar to detect the presence of vehicles up to approx-
imately 100 m (328 ft.) ahead, determines the current vehicle-to-vehicle fol-
lowing distance, and operates to maintain a suitable following distance from
the vehicle ahead. The desired vehicle-to-vehicle distance can also be set
by operating the vehicle-to-vehicle distance switch.

When driving on downhill slopes, the vehicle-to-vehicle distance may become
shorter.

Example of constant speed cruising

When there are no vehicles ahead

The vehicle travels at the speed set by the driver.

Example of deceleration cruising and follow-up cruising

When a preceding vehicle driving slower than the set speed appears

4-5. Using the driving support systems

When the turn signal lever is operated and your vehicle moves to an overtaking lane
while driving at 80 km/h (50 mph) or more, the vehicle will accelerate to help to over-
take a passing vehicle.
The system’s identification of what is an overtaking lane may be determined solely
based on the location of the steering wheel in the vehicle (left side driver position
versus right side driver position.) If the vehicle is driven to a region where the over-
taking lane is on a different side from where the vehicle is normally driven, the vehi-
cle may accelerate when the turn signal lever is operated in the opposite direction to
the overtaking lane (e.g., if the driver normally operates the vehicle in a region
where the overtaking lane is to the right but then drives to a region where the over-
taking lane is to the left, the vehicle may accelerate when the right turn signal is acti-
vated).

Example of acceleration

When there are no longer any preceding vehicles driving slower than the
set speed

The system accelerates until the set speed is reached. The system then returns to
constant speed cruising.

Press the cruise control main
switch to activate the cruise con-
trol.

WARNING

■

Before using dynamic radar

cruise control

●

Driving safely is the sole responsi-

bility of the driver. Do not rely solely

on the system, and drive safely by
always paying careful attention to

your surroundings.

●

The dynamic radar cruise control

provides driving assistance to
reduce the driver’s burden. How-

ever, there are limitations to the

assistance provided.

Read the following conditions care-
fully. Do not overly rely on this system
and always drive carefully.

WARNING

●

Set the speed appropriately

depending on the speed limit, traffic
flow, road conditions, weather con-

ditions, etc. The driver is responsi-

ble for checking the set speed.

●

Even when the system is function-

ing normally, the condition of the
preceding vehicle as detected by

the system may differ from the con-

dition observed by the driver.
Therefore, the driver must always

remain alert, assess the danger of

each situation and drive safely.
Relying solely on this system or

assuming the system ensures

safety while driving can lead to an
accident, resulting in death or seri-

ous injury.

●

Switch the dynamic radar cruise

control setting to off, using the

cruise control main switch when not
in use.

■

Cautions regarding the driving
assist systems

Observe the following precautions, as

there are limitations to the assistance
provided by the system. Failure to do

so may cause an accident resulting in

death or serious injury.

●

Assisting the driver to measure fol-

lowing distance

The dynamic radar cruise control is
only intended to help the driver in
determining the following distance
between the driver’s own vehicle and
a designated vehicle traveling ahead.
It is not a mechanism that allows
careless or inattentive driving, and it
is not a system that can assist the
driver in low-visibility conditions.
It is still necessary for driver to pay
close attention to the vehicle’s sur-
roundings.

●

Assisting the driver to judge proper

following distance

The dynamic radar cruise control
determines whether the following dis-
tance between the driver’s own vehi-
cle and a designated vehicle traveling
ahead is within a set range. It is not
capable of making any other type of
judgement. Therefore, it is absolutely
necessary for the driver to remain vig-
ilant and to determine whether or not
there is a possibility of danger in any
given situation.

●

Assisting the driver to operate the

vehicle

The dynamic radar cruise control
does not include functions which will
prevent or avoid collisions with vehi-
cles ahead of your vehicle. Therefore,
if there is ever any possibility of dan-
ger, the driver must take immediate
and direct control of the vehicle and
act appropriately in order to ensure
the safety of all involved.

■

Situations unsuitable for
dynamic radar cruise control

Do not use dynamic radar cruise con-

trol in any of the following situations.
Doing so may result in inappropriate

speed control and could cause an

accident resulting in death or serious
injury.

●

Roads where there are pedestrians,
cyclists, etc.

●

In heavy traffic

●

On roads with sharp bends

●

On winding roads

●

On slippery roads, such as those
covered with rain, ice or snow

252

4-5. Using the driving support systems

When driving on downhill slopes, the vehicle-to-vehicle distance may become
shorter.

WARNING

●

On steep downhills, or where there

are sudden changes between sharp
up and down gradients

Vehicle speed may exceed the set

speed when driving down a steep hill.

●

At entrances to freeways and high-

ways

●

When weather conditions are bad

enough that they may prevent the
sensors from detecting correctly

(fog, snow, sandstorm, heavy rain,

etc.)

●

When there is rain, snow, etc., on

the front surface of the radar or
front camera

●

In traffic conditions that require fre-
quent repeated acceleration and

deceleration

●

When your vehicle is towing a

trailer or during emergency towing

●

When an approach warning buzzer

is heard often

Example of constant speed cruising

When there are no vehicles ahead

The vehicle travels at the speed set by the driver.

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 deceler-
ates your vehicle. When a greater reduction in vehicle speed is necessary, the sys-
tem applies the brakes (the stop lights will come on at this time). The system will
respond to changes in the speed of the vehicle ahead in order to maintain the vehi-
cle-to-vehicle distance set by the driver. Approach warning warns you when the sys-
tem cannot decelerate sufficiently to prevent your vehicle from closing in on the
vehicle ahead.
When the turn signal lever is operated and your vehicle moves to an overtaking lane
while driving at 80 km/h (50 mph) or more, the vehicle will accelerate to help to over-
take a passing vehicle.
The system’s identification of what is an overtaking lane may be determined solely
based on the location of the steering wheel in the vehicle (left side driver position
versus right side driver position.) If the vehicle is driven to a region where the over-
taking lane is on a different side from where the vehicle is normally driven, the vehi-
cle may accelerate when the turn signal lever is operated in the opposite direction to
the overtaking lane (e.g., if the driver normally operates the vehicle in a region
where the overtaking lane is to the right but then drives to a region where the over-
taking lane is to the left, the vehicle may accelerate when the right turn signal is acti-
vated).

Example of acceleration

When there are no longer any preceding vehicles driving slower than the
