sunroof while it is closing, the
automatic reversal system will
detect the object and stop the
sunroof.
See Sunroof 0 58 .
Performance and
Maintenance Traction Control/
Electronic Stability
Control The vehicle has a traction control
system that limits wheel spin and
the StabiliTrak system that assists
with directional control of the vehicle
in difficult driving conditions. Both
systems come on automatically
when the vehicle is started and
begins to move.
.
To turn off traction control, press
and release
g on the instrument
panel to the left of the steering
wheel. The traction off light
idisplays in the instrument
cluster. The appropriate DIC
message displays.
.
To turn off both traction control
and StabiliTrak, press and hold
g until
i and
g illuminate in the
instrument cluster and the
appropriate DIC message
displays. .
Press and release
g again to
turn on both systems.
StabiliTrak will automatically turn on
if the vehicle exceeds 56 km/h
(35 mph). Traction control will
remain off.
See Traction Control/Electronic
Stability Control 0 229 .
Tire Pressure Monitor This vehicle may have a Tire
Pressure Monitor System (TPMS).
The low tire pressure warning light
alerts to a significant loss in
pressure of one of the vehicle's
tires. If the warning light comes on,
stop as soon as possible and inflate
the tires to the recommended
pressure shown on the Tire and

GMC Yukon/Yukon XL/Denali Owner Manual (GMNA-Localizing-U.S./
Canada/Mexico-11349262) - 2018 - crc - 6/20/17
In Brief 25Loading Information label. See
Vehicle Load Limits 0 200 . The
warning light will remain on until the
tire pressure is corrected.
The low tire pressure warning light
may come on in cool weather when
the vehicle is first started, and then
turn off as the vehicle is driven. This
may be an early indicator that the
tire pressures are getting low and
the tires need to be inflated to the
proper pressure.
The TPMS does not replace normal
monthly tire maintenance. Maintain
the correct tire pressures.
See Tire Pressure Monitor System
0 329 .
Tire Fill Alert (If Equipped)
This feature provides visual and
audible alerts outside the vehicle to
help when inflating an underinflated
tire to the recommended cold tire
pressure. See “ Tire Fill Alert (If
Equipped) ” under Tire Pressure
Monitor Operation 0 330 . Fuel (L83 5.3L V8 Engine) Regular Fuel
Use only unleaded gasoline rated
87 octane or higher in your vehicle.
Do not use gasoline with an octane
rating lower as it may result in
vehicle damage and lower fuel
economy. See Fuel 0 254 .
Fuel (L86 6.2L V8 Engine)
Premium Recommended Fuel
Use premium 93 octane unleaded
gasoline in your vehicle. Unleaded
gasoline with an octane rating as low as 87 may be used, but it will
reduce performance and fuel
economy. See Fuel 0 254 .
E85 or FlexFuel
FlexFuel Possible
Certain models are compatible with
E85 fuel. See E85 or FlexFuel
0 256 .
Engine Oil Life System The engine oil life system calculates
engine oil life based on vehicle use
and displays a DIC message when
it is necessary to change the engine
oil and filter. The oil life system
should be reset to 100% only
following an oil change.
