Since adaptive cruise control is not available on the i4 Tech, we may not be missing much. The LKAS-LDW on my I4 Tech is fabulous for my needs when on the freeway above 45 mph.
The operator's guide is not consistent in explaining whether the Cruise button or the Cancel button is the primary control and what effect this has on the LKAS-LDW system in non-advanced vehicles.
Summest?
I would love to try adaptive cruise control. That's one of the things I really like about the advance package, that I did not get. I would volunteer to work out the bugs.
Main is the
main / primary control. If you shut off Main, both
LKAS and
Cruise Control are disabled.
I didn't realize that cancel also cancels LKAS. I thought it was only used to cancel cruise control? I will have to check on the way home.
By having
Main on, you have the ability to turn on LKAS and Cruise Control.
Cancel works good on the cruise control because you don't need to brake to exit cruise control and you don't have to hit main to turn it off.
Cancel also allows your set speed to stick so that when you hit
RESume, you revert back to your set speed. This is great when you have the speed set to 70 mph and you need to pass someone doing less than 70 mph. Press cancel, accelerate and once back in your lane press resume. If you use main to stop cruise control, you lose your preset speed.
It is odd to have to switch on
Main and
Cruise Control and then you still have to select SET to get it to work.
LDW is controlled by the switch down on the lower part of the dash near the door. If has a icon of a car crossing over the line in the road with a green light when it is on. On the V6,
LDW, RDW and LKAS are tightly weaved together and becomes confusing. Luckily on the I4 Tech they are a bit more distinguishable.
