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 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).
