SERVICE TRAILER BRAKE SYSTEM
On vehicles with the Integrated Trailer Brake Control
(ITBC) system, this message displays and a chime
sounds when there is a problem with the ITBC system.
When this message displays, power is no longer
available to the trailer brakes.
As soon as it is safe to do so, carefully pull your vehicle
over to the side of the road and turn the ignition off.
Check the wiring connection to the trailer and turn the
ignition back on. If this message still displays, either your
vehicle or the trailer needs service. See your
dealer/retailer.
See “Integrated Trailer Brake Control System” under
Towing a Trailer on page 4-50 for more information.
SIDE BLIND ZONE ALERT
SYSTEM OFF
If your vehicle has the Side Blind Zone Alert (SBZA)
system, this message displays when the SBZA system
has been turned off. See Side Blind Zone Alert
(SBZA) on page 2-58 and DIC Operation and Displays
(With DIC Buttons) on page 3-52 or DIC Operation
and Displays (Without DIC Buttons) on page 3-58 for
more information.
SIDE BLIND ZONE SYS. (System)
UNAVAILABLE
If your vehicle has the Side Blind Zone Alert (SBZA)
system, this message displays when the SBZA system
is disabled because the sensor is blocked and cannot
detect vehicles in your blind zone. The sensor may
be blocked by mud, dirt, snow, ice, or slush. This
message may also display during heavy rain or due to
road spray. It may also come on when driving in
isolated areas with no guardrails, trees, or road signs
and light traffic. Your vehicle does not need service. For
cleaning instructions, see Washing Your Vehicle on
page 5-110. See Side Blind Zone Alert (SBZA) on
page 2-58 for more information.
STABILITRAK OFF
If your vehicle has StabiliTrak, this message displays
when you turn off StabiliTrak, or when the stability control
has been automatically disabled. To limit wheel spin and
realize the full benefits of the stability enhancement
system, you should normally leave StabiliTrak on.
However, you should turn StabiliTrak off if your vehicle
gets stuck in sand, mud, ice, or snow and you want to
rock your vehicle to attempt to free it, or if you are driving
in extreme off-road conditions and require more wheel
spin. See If Your Vehicle is Stuck in Sand, Mud, Ice, or
Snow on page 4-31. To turn the StabiliTrak system on or
off, see StabiliTrak
