GMC Terrain: Warning Lights, Gauges, and Indicators / Security Light

The security light should come on
briefly as the engine is started. If it
does not come on, have the vehicle
serviced by your dealer. If the
system is working normally, the
indicator light turns off.
If the light stays on and the engine
does not start, there could be a
problem with the theft-deterrent
system. See Immobilizer Operation.
This light, a Driver Information
Center (DIC) Message, and a chime
come on when there is an issue with
the DEF.
If the DEF issue has not been
corrected, the light will continue to
flash...
High-Beam On Light
This light comes on when the
high-beam headlamps are in use.
See Headlamp High/Low-Beam
Changer.
IntelliBeam Light
This light comes on when the
IntelliBeam system, if equipped, is
enabled...
Other information:
Tires should be rotated every
12 000 km (7,500 mi). See
Maintenance Schedule.
Tires are rotated to achieve a
more uniform wear for all tires.
The first rotation is the most
important.
Anytime unusual wear is
noticed, rotate the tires as soon
as possible, check for proper tire
inflation pressure, and check for
damaged tires or wheels...
If the cruise control system is
already activated:
Press and hold +RES on the
steering wheel until the vehicle
accelerates to the desired
speed, then release it.
To increase the speed in small
increments, briefly press +RES.
For each press, the vehicle goes
about 1 km/h (1 mph) faster...
