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 404.To
turn the StabiliTrak
®
system on or off, see
StabiliTrak
®
System on page 363.
There are several conditions that can cause this
message to appear.
One condition is overheating, which could
occur if StabiliTrak
®
activates continuously
for an extended period of time.
The message also displays if the brake
system warning light is on. See Brake System
Warning Light on page 249.
The message could display if the stability
system takes longer than usual to complete its
diagnostic checks due to driving conditions.
The message displays if an engine or vehicle
related problem has been detected and the
vehicle needs service. See your dealer.
The message also displays if the vehicle is
shifted into 4LO.
The message turns off as soon as the conditions
that caused the message to be displayed are
no longer present.
TIGHTEN GAS CAP
This message may display along with the check
engine light on the instrument panel cluster if
the vehicle’s fuel cap is not tightened properly. See
Malfunction Indicator Lamp on page 253.
Reinstall the fuel cap fully. See Filling the Tank on
page 451. The diagnostic system can determine
if the fuel cap has been left off or improperly
installed. A loose or missing fuel cap allows fuel to
evaporate into the atmosphere. A few driving
trips with the cap properly installed should turn this
light and message off.
