1. SYSTEM DESCRIPTION
1) Overview
The cruise control is an automatic speed control system that maintains a desired driving speed
without using the accelerator pedal.
The vehicle speed must be greater than 38 km/h to engage the cruise control. This feature is
especially useful for motorway driving.
The cruise control system is a supplementary system, which helps the driver to drive the
vehicle at a desired speed without using the accelerator pedal under the traffic condition
where the vehicle-to-vehicle distance meets the legal requirement..

2) Traffic Conditions for Using Cruise Control
Use the cruise control system only when the traffic is not jammed, driving on motorways or
highways where there is no sudden change in the driving condition due to traffic lights,
pedestrian, etc.
Improper use of the cruise control could be dangerous.
Do not use on winding roadsyy .
Do not use in heavy traffic.
Do not use on slippery, wet roads. -

-
This could result in a loss of control, collision, and/or personal injuries.

2. CONFIGURATION
1) Circuit Diagram
The engine ECU detects the operating conditions of cruise control system, and monitors the
braking performance, vehicle speed, road conditions and ESP system operation. If the engine
ECU determines that there are not any problem to drive in cruise control mode, the vehicle can be
operated by cruise switch signals (decelerating, accelerating, cruising).

3. OPERATION
1) Setting a Desired Speed
To operate the cruise control, accelerate to the desired speed, which must be more than 36
km/h and less than 150 km/h.
When the desired speed is reached, push up the ACCEL switch of the cruise control lever or
push down the DECEL switch for 1 second per one switching and then release the accelerator
pedal slowly.
Now, the vehicle is cruised by this system with the set speed. You don't need to use the
accelerator pedal.
Refer to the following pages for details of operation. 1.

Never use the cruise control system until you get used to it.
Improper use or not fully aware of this function could result in collision and/or personal injuries.

2) Accelerating with the Cruise Control System
(1) While the cruise control system is running
Push up the ACCEL switch of the cruise control lever and hold it until the desired speed is
reached without an accelerator pedal intervention.
When the desired speed is reached, release the leve 1.
2.
(2) When the cruise control system is not running
To increase the speed with the cruise control system while the system is not running, follow the
procedures below.
Accelerate using the accelerator pedal over 36 km/h.
Push up the ACCEL switch of the cruise control lever and hold it. And then release the
accelerator pedal slowly.
When the desired speed is reached, release the lever. 1.

(3) Tap-up while the cruise control system is running
To increase the vehicle speed in stages while the cruise control system is running, follow the
procedures below.
Push up the ACCEL switch of the cruise control lever less than 0.5 second per one switching
while the cruise control system is running. This is a tap-up switching. When you operate a tap-
up switching, the vehicle is accelerated for 1.3 km/h over the previous set speed.
If you want to accelerate for 13 km/h, operate the tap-up switching ten times without
accelerating with the cruise control system. 1.

3) Decelerating with the Cruise Control System
(1) While the cruise control system is running
Push down the DECEL switch of the cruise control lever and hold it until the desired speed is
reached without a brake pedal intervention. But the cruise control system cannot maintain the
cruise function at less than 34 km/h.
When the desired speed is reached, release the lever. 1.
2.
(2) When the cruise control system is not running
To decrease the vehicle speed with the cruise control system when the system is not running,
follow the procedures below.
Push down the cruise control switch lever to DECEL side and hold it until the desired speed is
reached while the vehicle speed is over 36 km/h.
And then release the accelerator pedal slowly.
When the desired speed is reached, release the lever. But the cruise control system cannot
maintain the cruise function at less than 34 km/h. 1.

(3) Tap-down while the cruise control system is running
To decrease the vehicle speed in stages while the cruise control system is running, follow the
procedures below.
Push down the DECEL switch of the cruise control lever less than 0.5 second per one switching
while the cruise control system is running. This is a tap-down switching. When you operate a
tap-down switching, the vehicle is decelerated for 1.0 km/h below the previous set speed.
If you want to decelerate for 10 km/h, operate the tap-down switching ten times without the
brake pedal intervention. 1.
