The MyMack Driver App from Mack Trucks is a driver application for the Mack Pioneer highway model. The app is available to download from the Apple Store and Google Play, and allows drivers to remotely monitor their truck's fuel level, Diesel Exhaust Fluid (DEF) level, oil level, and check the status of their vehicle's lights. Additionally, the app lets drivers remotely activate their climate control system when equipped with Mack's Integrated Parking Cooler.
