Maintenance - GMC 2015 Sierra Denali Owner's Manual

Keep the path under the front
seats clear of objects to help
circulate the air inside of the
vehicle more effectively.
Use of non-GM approved hood
deflectors can adversely affect
the performance of the system.
Check with your dealer before
adding equipment to the outside
of the vehicle.
