Stabilitrak Off - Hummer H2 2009 Owner's Manual

STABILITRAK OFF

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 4-39. To turn the
StabiliTrak system on or off, see StabiliTrak
on page 4-6.
There are several conditions that can cause this
message to appear.
•
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 3-40. Reinstall the fuel cap
fully. See Filling the Tank on page 5-8. 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.
