Tips to Safely Clean Car Seats That Are Dirty | Complete Car Interior Cleaning Guide How to Safely Clean Car Seats Stained With Food and Drinks: A Parent’s Guide AutoReviewUS - If you have kids, you already know that a car seat can become a magnet for spilled milk, juice, crackers, yogurt, chocolate, crumbs, and other leftovers.

The good news is that this behavior is usually understandable—and preventable. This guide explains why manual cars roll backward on hills, what causes the powerful kick, how to perform a controlled hill start, how much clutch wear the technique can create, and how modern Hill Start Assist systems change the experience.

First Drive MG HS Magnify i-SMART: A Tech-Loaded SUV That Makes a Strong Case for MG MG HS Magnify i-SMART AutoReviewUS - When MG introduced the HS Magnify i-SMART , it was trying to challenge a familiar formula in the midsize SUV market: buyers wanted the practicality and comfort of a family crossover, but increasingly expected technology normally associated with more expensive vehicles. The result is an interesting combination of a turbocharged gasoline engine, seven-speed dual-clutch transmission, extensive driver-assistance technology, smartphone connectivity, voice commands, and remote vehicle functions.
