Precautions While Driving With Acc - Jeep WRANGLER 2020 Owner's Manual

252 STARTING AND OPERATING
When the condition that created limited
functionality is no longer present, the system
will return to full functionality.
NOTE:
If the "ACC/FCW Limited Functionality Clean
Front Windshield" message occurs frequently
(e.g. more than once on every trip) without any
snow, rain, mud, or other obstruction, have the
windshield and forward facing camera
inspected at an authorized dealer.
"Service ACC/FCW" Warning
If the system turns off, and the instrument cluster
displays "ACC/FCW Unavailable Service
Required" or "Cruise/FCW Unavailable Service
Required", there may be an internal system fault
or a temporary malfunction that limits ACC
functionality. Although the vehicle is still drivable
under normal conditions, ACC will be temporarily
unavailable. If this occurs, try activating ACC
again later, following an ignition cycle. If the
problem persists, see an authorized dealer.

Precautions While Driving With ACC

In certain driving situations, ACC may have
detection issues. In these cases, ACC may
brake late or unexpectedly. The driver needs to
stay alert and may need to intervene.
NOTE:
Do not put stickers or easy passes over the

camera/radar field of view.
Cracks in the windshield may affect the

performance of ACC, depending on the size
and location of the crack.
Towing A Trailer
Towing a trailer is not advised when using ACC.
Offset Driving
ACC may not detect a vehicle in the same lane
that is offset from your direct line of travel, or a
vehicle merging in from a side lane. There may
not be sufficient distance to the vehicle ahead.
The offset vehicle may move in and out of the
line of travel, which can cause your vehicle to
brake or accelerate unexpectedly.
