Traction Control Off - GMC 2008 Yukon Owner's Manual

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 3-44.
•
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
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 3-48. Reinstall the fuel cap fully.
See Filling the Tank on page 5-9. 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.
TIRE LEARNING ACTIVE
This message displays when the Tire Pressure Monitor
System (TPMS) is re-learning the tire positions on your
vehicle. The tire positions must be re-learned after
rotating the tires or after replacing a tire or sensor. See
Tire Inspection and Rotation on page 5-78, Tire Pressure
Monitor System on page 5-73, and Inflation - Tire
Pressure on page 5-72 for more information.

TRACTION CONTROL OFF

If your vehicle has StabiliTrak
