The Titan’s standard power windows allow the driver or passenger to lower and raise the windows without leaning over or being distracted. Power windows cost extra on the Sierra.
The Titan’s front power windows open or close with one touch of the switches, making it more convenient at drive-up windows and toll booths, or when talking with someone outside of the car. The Sierra’s optional power windows’ front passenger window doesn’t close automatically.
If the front windows are left down on the Titan the driver can raise them using the key in the outside lock cylinder. On a hot day the driver can lower the windows from outside the vehicle using the key in the outside lock cylinder or the keyless remote. The driver of the Sierra can only operate the windows from inside the vehicle, with the ignition on.
The Pushbutton Start standard on the Titan S/SV allows you to start the engine without removing a key from pocket or purse (optional Intelligent Key will also allow unlocking the driver’s door without taking your keys out). The GMC Sierra doesn’t offer an advanced key system.
The Titan S/SV’s standard speed-sensitive wipers speed up when the vehicle does, so that the driver doesn’t have to continually adjust the speed of the wipers. The Sierra’s manually variable intermittent wipers have to be constantly adjusted. The Titan’s optional wipers adjust their speed and turn on and off automatically according to the amount of rainfall on the windshield.
Both the Titan and the Sierra offer rear vents. For greater rear passenger comfort, the Titan offers optional rear air conditioning vents to keep rear occupants cool in summer or warm in winter. The Sierra doesn’t offer rear air conditioning vents, only heat vents.
Bluetooth wireless connectivity is standard on the Titan, connecting the driver and passenger’s cell phones to the vehicle systems. This allows them to use the vehicle’s stereo and hand controls to place calls safely and easily. Bluetooth costs extra on the Sierra.
