StabiliTrak®– Stability Control
System with Traction Control
StabiliTrak combines antilock brake,
traction control, and stability control sys-
tems that help the driver maintain direc-
tional control of the vehicle in most driv-
ing conditions. The system is designed
to help keep the vehicle on the driver’s
intended path by using throttle and
brake intervention.
When activated, the system will apply
braking to individual wheels and may
reduce engine power as necessary to
help you maintain directional control of
the vehicle. You may also hear a noise
or vibration, or feel a reduction in accel-
eration, while the system is active. This
is normal.
StabiliTrak is automatically turned on
when the vehicle is started and does
not require any driver input. It is recom-
mended to leave the system on at all
times for normal driving. It may be
necessary to turn off the traction control
portion of the system if the vehicle is
stuck in sand, mud or snow.
• To turn off the traction control portion
of StabiliTrak, press and release the
(StabiliTrak) button located on
the transmission shift lever. TRAC-
TION CONTROL OFF will be dis-
played on the Driver Information
Center (DIC). Press the button again
to turn the system back on.
• To turn off StabiliTrak, which includes
traction control and stability control
functions, press and hold the
(StabiliTrak) button for five seconds.
STABILITRAK OFF will be displayed
on the DIC. Press the button again
to turn the system back on.

Getting to Know Your Envoy18
Tire Pressure Monitor
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 on the instru-
ment panel cluster. The low tire pressure
warning light will remain on until you
correct the tire pressure. A CHECK TIRE
PRESSURE message will also appear
on the DIC.
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 clear the DIC
message 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.
Note: The Tire Pressure Monitor can
alert you about low tire pressure, but it
doesn’t replace normal monthly tire
maintenance.
Tire Inflator Kit (if equipped)
Your vehicle may not have a spare tire
or a jack. In case of a flat tire, a tire
inflator kit is provided to seal small
punctures in the tread area of the tire.
The kit is located in the storage com-
partment in the floor of the rear cargo
area. Refer to the tire inflator kit instruc-
tions for complete operating information.
See Section 5 of your Owner Manual.
