Performance and
Maintenance
Traction Control/
Electronic Stability
Control
The Traction Control System (TCS)
limits wheel slip. The system is on
when the vehicle is started.
The StabiliTrak system assists with
directional control of the vehicle in
difficult driving conditions. The
system is on when the vehicle is
started.
TCS and StabiliTrak can be turned
off or on using the Driver
Information Center (DIC) controls.
See Traction Control/Electronic
Stability Control 0213.
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
Loading Information label. See
Vehicle Load Limits 0181. 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.

speeds greater than
50 km/h (30 mph) to clean the DPF
effectively.
Special DPF Driver Messages
If the vehicle is used for numerous
short trips or extended slow-speed
operation, the engine computer may
not be able to clean the DPF
effectively. If this happens, a Driver
Information Center (DIC) message
will display.
If the vehicle continues to be driven
in a manner that prevents effective
DPF cleaning, the DPF will become
plugged. If this occurs, the engine
computer will turn on the
malfunction indicator lamp in the
instrument cluster and a DIC
message will display. SeeDiesel
Particulate Filter 0197, Fuel for
Diesel Engines 0238 andEngine
Oil 0269.
Diesel Exhaust Fluid
Diesel Exhaust Fluid (DEF) is used
with diesel engines to reduce the
amount of regulated emissions
produced. The DEF system must be maintained for the vehicle to run
properly. It is normal to hear the
DEF system purge fluid back into
the tank after the vehicle is shut off.
Locating Diesel Exhaust Fluid
DEF can be purchased at a GMC
dealer. It can also be purchased at
authorized vehicle dealerships.
Additionally, some diesel fueling
stations or retailers may have DEF.
For vehicles with an active OnStar
service plan, OnStar can help to
locate a DEF retailer. See
Customer
Assistance Offices 0371 for phone
numbers to assist you in contacting
a GM dealer. See Recommended
Fluids and Lubricants 0361.
As the DEF tank becomes low on
fluid, warnings begin with
approximately 1 600 km (1,000 mi)
of remaining range. These warnings
will increase in intensity as the tank
becomes empty. Once the tank is
empty, the vehicle speed will be
limited. If there is an issue with the
quality of the fluid or the exhaust
fluid system, warnings will be displayed in the Driver Information
Center (DIC). See
Diesel Exhaust
Fluid 0198.
