The Blazer’s instruments include an oil pressure gauge and a temperature gauge - which could save your engine! Often ‘idiot lights’ don’t warn you until damage has been done. The Santa Fe does not have an oil pressure gauge.
The Blazer’s front and rear power windows all lower 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 Santa Fe’s standard power windows’ passenger windows don’t open automatically.
In case you lock your keys in your vehicle, or don’t have them with you, you can let yourself in using the Blazer LT/RS/Premier’s available exterior PIN entry system. The Santa Fe doesn’t offer an exterior PIN entry system, and its Blue Link can’t unlock the doors if the vehicle doesn’t have cell phone reception or the driver can’t contact the service.
The Blazer’s standard Keyless Open and Start allow you to unlock the doors from any outside door handle, unlock the cargo door, and start the engine, all without removing the key from the pocket or purse. Proximity Key standard on the Santa Fe doesn’t offer a sensor on the rear doors, so you’ll have to reach a front handle to unlock the rear door.
The Blazer’s optional rear and side view mirrors have an automatic dimming feature. These mirrors can be set to automatically darken quickly when headlights shine on them, keeping following vehicles from blinding or distracting the driver. The Santa Fe offers an automatic rear view mirror, but its side mirrors don’t dim.
The Blazer 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 Santa Fe SEL/XRT/Limited/Calligraphy.
