CAUTION
■The information display at low temperatures
Allow the interior of the vehicle to warm up before using the liquid crystal informa-
tion display. At extremely low temperatures, the information display monitor may
respond slowly, and display changes may be delayed.
For example, there is a lag between the driver's downshifting and the new gear
number appearing on the display. In this case, wait until the display changes and
take care not to downshift again, causing rapid and excessive engine braking and
possibly an accident resulting in death or serious injury.

Dynamic radar cruise control∗
Dynamic radar cruise control supplements conventional cruise control
with a vehicle-to-vehicle distance control. In vehicle-to-vehicle distance
control mode, the vehicle automatically accelerates or decelerates in
order to maintain a set following distance from vehicles ahead.

■Adjusting the set speed
To change the set speed, operate the lever until the desired set
speed is displayed.
Increases the speed
Decreases the speed
Fine adjustment: Momentarily
move the lever in the desired
direction.
Large adjustment: Hold the
lever in the desired direction.
In the vehicle-to-vehicle distance control mode, the set speed will be
increased or decreased as follows:
• When the set speed is shown in “MPH” Fine adjustment: By approximately 5 mph (8 km/h) each time the lever
is operated
Large adjustment: By approximately 5 mph (8 km/h) for each 0.75
seconds the lever is held
• When the set speed is shown in “km/h” Fine adjustment: By approximately 3.1 mph (5 km/h) each time the
lever is operated
Large adjustment: By approximately 3.1 mph (5 km/h) for each 0.75
seconds the lever is held
In the constant speed control mode ( →P.188), the set speed will be
increased or decreased as follows:
Fine adjustment: By approximately 1 mph (1.6 km/h) each time the lever is
operated
Large adjustment: The set speed can be increased or decreased continu-

■Changing the vehicle- to-vehicle distance
Pressing the button changes the
vehicle-to-vehicle distance as
follows:
Long
Medium
Short
The vehicle-to-vehicle distance
is set automatically to long
mode when the “ENGINE
START STOP” switch is turned
to IGNITION ON mode.
If a vehicle is running ahead of
you, the preceding vehicle mark
will also be displayed.
■Vehicle-to-vehicle distance settings
Select a distance from the table below. Note that the distances
shown correspond to a vehicle sp eed of 50 mph (80 km/h). Vehi-
cle-to-vehicle distance increases/decreases in accordance with
vehicle speed.

When driving
IS F_UExample of follow-up cruising
When following a vehicle driving slower than the set speed
The system continues follow-up cruising while adjusting for changes in the
speed of the vehicle ahead in order to maintain the vehicle-to-vehicle dis-
tance set by the driver.
Example of acceleration
When there are no longer any vehicles ahead driving slower than the
set speed
The system accelerates until the set speed is reached. The system then
returns to constant speed cruising.
Approach warning
When your vehicle is too close to a vehicle ahead, and sufficient auto-
matic deceleration via the cruise control is not possible, the display will
flash and buzzer will sound to alert the driver. An example of this would
be if another driver cuts in front of you while you are following a vehicle.
Apply the brakes to ensure an appropriate vehicle-to-vehicle distance.
■ Warnings may not occur when
In the following instances, there is a possibility that the warnings will not
occur:
●When the speed of the vehicle ahead matches or exceeds your
vehicle speed
● When the vehicle ahead is traveling at an extremely slow speed
● Immediately after the cruise control speed was set
● At the instant the accelerator is applied

Intuitive parking assist∗
∗: If equipped
The distance to obstacles measured by the sensors is communicated via
the multi-information display and a buzzer when parallel parking or
maneuvering into a garage. Always check the surrounding area when
using this system.
For vehicles equipped with a navigation system, refer to the separate
“Navigation System Owner’s Manual” for further details.
