You usually can drive the car even if the Stabilitrak System light is on but at a greatly increased risk to your safety and your passengers. You will notice loss of power as well as the throttle response being sluggish but the vehicle will still get you where you need to go. However we feel compelled to let you know that while it can still transport you, your drive is more susceptible to fishtailing in less than ideal driving conditions. If you are in an area where there is light snow or wet driving conditions, make sure that this system is in top condition before you venture out.
