Congrats on the purchase Ehtesham bhai.
Warranty covers all manufacturing defects arising due to manufacturing and quality including, electrical, engine, mechanical and physical components. This excludes regular wear items that fall under maintenance.
But for warranty to be valid car needs to be in complete stock condition else warranty for that entire category will be null and void. Also warranty is only valid if a car is throughout 3S maintained with all stamps and entries on warranty book.
For example if tyre size is different than stock then suspension and mechanical warranty is void, if you have changed speakers then entire electrical warranty stands void. No DIY jobs on the car. HIDs or unspecified wattage bulbs or aftermarket lights void warranty.
