Stabilitrak Off - GMC Sierra 2010 Owner's Manual

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 5 28. To turn the
StabiliTrak system on or off, see StabiliTrak
on page 5 6.
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 4 39.
4-72
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/retailer.
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
®
System
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 4 42. Reinstall the fuel cap fully. See
Filling the Tank on page 6 11. 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.
