Brake message
 
I just bought a 14 GC Overland.
When I was driving it home, I tried out the curise control.

At some point, everthing on the dash went out and a large word BRAKE appeared. Well, that got my attention and I'm now focused on the dash. I wasn't in any traffic. And when I looked back up, there really wasn't any thing around me.

Anyway, what are the conditions that causes this "brake" alert?

Thanks

Tom

Were you on a curve when this happened? It has happened to me twice, both times at the same location, on a curve where large trees were growing alongside the road. The system saw the trees as a possible collision situation and sounded the alert. Hasn't happened since.

From the manual:

FORWARD COLLISION WARNING (FCW) WITH
MITIGATION IF EQUIPPED
Forward Collision Warning (FCW) With Mitigation
Operation
The Forward Collision Warning (FCW) system with
mitigation provides the driver with audible warnings,
visual warnings (within the EVIC), and may apply a
brake jerk to warn the driver when it detects a potential
frontal collision. The warnings and limited braking are
intended to provide the driver with enough time to react,
avoid or mitigate the potential collision.
NOTE: FCW monitors the information from the forward
looking sensors as well as the Electronic Brake Controller
(EBC), to calculate the probability of a forward collision.
When the system determines that a forward collision is
probable, the driver will be provided with audible and
visual warnings and may provide a brake jerk warning.

If the driver does not take action based upon these
progressive warnings, then the system will provide a
limited level of autonomous braking to help slow the
vehicle and mitigate the potential forward collision. If the
driver reacts to the warnings by braking and the system
determines that the driver intends to avoid the collision
by braking but has not applied sufficient brake force, the
system will compensate and provide additional brake
force as required.
When the system determines a collision with the vehicle
in front of you is no longer probable, the warning
message will be deactivated.

NOTE:
The minimum speed for FCW activation is 5 mph
(10 km/h).
The FCW alerts may be triggered on objects other than
vehicles such as guard rails or sign posts based on the
course prediction. This is expected and is a part of
normal FCW activation and functionality

Thanks for the info.

I haven't got that far in the manuals (both are 600+ pages).

I bought my GC over the weekend and had time to take it out for a spin. But 3 days of commuting and haven't had any problems/concerns.....so far.

Mine was an trade in from a 2006 Commander Limited.
For how I drive it is definitely an upgrade.

I don't know how the 5.7 litter Hemi on the commander produced 330 horse power but this 3.6 litter 6 cylinder is only a reduction to 290 horse power.
