The cruise control backlighting on the "control stalk" blinks/flashes erratically in the driver¿s peripheral vision. This is quite dangerous and distracting. This happens at all speeds and driving conditions but seems to be worse when having to turn the steering wheel more (I. E. A parking lot vs. Changing lanes on the highway).
The cruise-control stalk light flickers at night causing distraction.
The speedometer & tachometer on the model has a dark background with small numbers and doesn't illuminate in the auto position. If the sun is bright with glare off other vehicles and you have to wear sun glasses they illuminate but the are either difficult to see or impossible. This is a safety concern, in my opinion, while you vehicle is in motion.
