The Dynamic Laser Cruise Control system has two cruise control modes:
1. Constant Speed Control Mode
 Thismodeisusedonconventionalcruisecontrolsystems.Itisalsocalled“xedspeed”controlmodeandisusedfor
cruisingatxedspeeds.
2. Vehicle-to-Vehicle Distance Control Mode
 Inthismode,thecruisecontrolsystemusesalasersensortodetectavehicleinfrontofyouandmeasuresthe
vehicle-to-vehicledistance.Thedetectionrangeofthesensorisabout394ft(120m)ahead.

STEP 1 - PREPARE THE WORK AREA
First, you will need to prepare a working area of 29.5 ft (9m) x 9.8 ft (3m) indoors, on level ground, and in front of
a blank wall away from any reflective objects.

STEP 2 - FIND THE CENTERLINE OF THE VEHICLE
To achieve the greatest accuracy with your measurements, start by finding the centerline of the vehicle. To do
this, hang a sharp-pointed plumb bob weight from the center of the back door emblem and front grill emblem,
then mark these center points on the ground with masking tape as shown (Points Aand B).

STEP 4 - MARK THE CENTERLINE OF THE WORK AREA
Now make a straight line on the ground using String #1 to align all three Points (A, Band C). Tape down the
string at Point Aand route the string under the vehicle to Point C.

• String #1 may be longer than is needed to make a straight line in this step.
• Make sure the string passes through Point B to ensure a straight line.
