1. OVERVIEW
1) System Description
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.
Auto cruise operated ECO cruise operated

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 the vehicle speed to the operating range.
* Operating range: - 38 km/h ~150 km/h
- higher than 3rd gear (M/T)
To set the desired speed, push up ACCEL switch or push down DECEL switch of the cruise control
lever when the vehicle speed is in the operating range,.
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.

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 lever. 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 38 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.
(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 km/h over the previous set speed.
If you want to accelerate for 10 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 38 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 40 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 38 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 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.
