The 1500 TRX’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 1500’s standard power windows’ front passenger window doesn’t close automatically.
The 1500 TRX’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 1500’s standard manually variable intermittent wipers have to be constantly adjusted.
To help drivers see further while navigating curves, the 1500 TRX has standard adaptive headlights to illuminate around corners automatically by reading vehicle speed and steering wheel angle. The Sierra 1500 doesn’t offer cornering lights.
The 1500 TRX has standard power remote mirrors. The Sierra 1500 only comes with remote mirrors at extra cost. Without them the driver will have to roll down the windows and reach across the car to adjust the mirrors.
The 1500 TRX’s standard outside mirrors include heating elements to clear off the mirrors for better visibility. GMC charges extra for heated mirrors on the Sierra 1500.
Optional air conditioned front and rear seats keep the 1500 TRX’s passengers comfortable and take the sting out of hot leather in summer. The Sierra 1500 doesn’t offer air-conditioned seats in the rear.
On extremely cold winter days, the 1500 TRX’s optional heated steering wheel provides comfort, allowing the driver to steer safely and comfortably before the vehicle heater warms up. The Sierra 1500 doesn’t offer a heated steering wheel.
The 1500 TRX has a standard dual zone air conditioning allows the driver and front passenger to choose two completely different temperatures so people with different temperature preferences won’t have to compromise. This makes both the driver and front passenger as comfortable as possible. Dual zone air conditioning is only available on the Sierra 1500 SLE/Elevation/SLT/AT4/Denali.
