Coming from experience with digital car features. I'd say don't touch it. We have a Ssanyong Tornado with digital dashboard. Brand new less than 6 months old from manufacture and the screen that is needed for Speedo and warning lights goes off. It then couldn't be driven so was off the road 3 month while they ordered the part from Korea, two months later it re-occured we were unable to fall back on manual methods as there were none so it made the car unsuitable to drive. Never again will I buy any car fully reliant on electric Speedos, doors or anything that cannot be overridden.
