Getting to Know Your Yukon/Yukon Denali22
StabiliTrak is an
advanced comput-
er-controlled vehicle
stability and traction
enhancement sys-
tem that assists
with directional control of the vehicle in
difficult driving conditions. It turns on
automatically every time you start your
vehicle.To limit wheelspin and help
maintain directional control, you should
always leave the system on. However, if
your vehicle becomes stuck and rocking
the vehicle is required, the system
should be turned off.
To turn off the traction control part of the
system, press the (StabiliTrak) but-
ton located below the climate controls
on the instrument panel.
To turn off the traction control and stabil-
ity enhancement systems, press and
hold the button for five seconds.
StabiliTrak®– Stability Control
System (if equipped)
The Tire Pressure Monitor alerts you
when a significant reduction in pressure
occurs in one or more of your vehicle’s
tires by illuminating the (Low Tire
Pressure) warning light, which will remain
on until you correct the tire pressure. You
may also have a CHECK TIRE PRES-
SURE message appear on the DIC
(if equipped).
Correcting the Tire Pressure
When the low tire pressure warning light
illuminates, you must inflate the tire to
the proper tire pressure (just as you
must refuel the vehicle when the low
fuel warning light illuminates). The Tire
and Loading Information label shows the
correct tire pressure for the tires when
they’re cold. “Cold” means your vehicle
has been sitting for at least three hours
or driven no more than one mile.
You can temporarily remove the DIC mes-
sage by acknowledging it with your DIC
controls. However, at the next vehicle
start-up, the DIC message will reappear if
the tire pressure has not been corrected.
During cooler conditions, the low tire
pressure warning light may appear when
the vehicle is first started and then turn
off as you start to drive. This could be
an early indicator that your tire pres-
sures are getting low and the tires need
to be inflated to the proper pressure.
See Section 5 of your Owner Manual.
Tire Pressure Monitor
Note:The Tire Pressure Monitor can alert
you about low tire pressure, but it doesn’t
replace normal monthly tire maintenance.
When the system is turned off, the
StabiliTrak light will illuminate.
See Section 4 of your Owner Manual.
To use this feature, move the shift lever
to the Manual (M) position and select a
lower or higher driving gear using the

Press the – (minus) side of the button to
downshift. When slowing to a stop, the
vehicle will automatically downshift.
Press the + (plus) side of the button to
upshift. As vehicle speed increases, you
will need to manually upshift.
If current vehicle speed is too high or
too low for the requested gear, the shift
will not occur.
See Section 2 of your Owner Manual.
