GMC
Hummer EV SUV 3X

Step on the brake, press the engine start button on the console or steering column; wait for the cluster to confirm ready before shifting out of P.

Console-mounted shifter with R-N-D-S notches; paddles behind the wheel for manual gear control.

Drive modes are accessed via the Drive Mode Selector on the console (PTM dial on Corvette). Available modes typically include Tour, Sport, Track, Weather, My Mode, Z-Mode (Corvette). Each mode reshuffles throttle mapping, steering weight, adaptive dampers (if equipped), exhaust valves, and stability-control thresholds. On performance trims, an 'Individual' or 'Custom' slot lets you save your favorite combination so you can recall it with one click instead of nesting through menus.

The driver display is a 8 to 12-inch reconfigurable digital cluster. Use the steering-wheel left thumb-pad to cycle layouts (Classic, Sport, Navigation, Minimal). When in Sport / Track mode the cluster automatically swaps to a wide tach with gear indicator and tire-temperature readout. The head-up display brightness, height, and content are configured from Settings → Displays → HUD.

Infotainment runs on Google built-in (Maps, Assistant, Play Store). Wireless Apple CarPlay and Android Auto are standard; pair from Settings → Connections the first time, then it auto-connects whenever your phone is in range. "Hey Google" wakes the in-car assistant for nav, climate, calls, and messaging without touching the screen. The main display also hosts vehicle-specific apps: tire pressures, performance data recorder (where fitted), drive-mode customizer, and the camera views.

Standard driver aids include adaptive cruise control, lane-keeping assist, automatic emergency braking, blind-spot monitoring, and rear cross-traffic alert. Toggle each system individually from the driver-assist menu (steering-wheel left-pad → Assistance). Highway-driving assist (hands-off in marked lanes on supported roads), automatic lane-change on indicator tap, traffic-jam assist for stop-and-go, and a 360° surround camera with transparent-hood mode are all available and worth enabling for the first time before driving in heavy traffic.

DC fast-charging happens through the CCS1 (or NACS, for newer 2025+ US-market models) port. Plug in, the car negotiates power automatically — typical 10–80% takes 18–28 minutes on a 350 kW charger. Level-2 home charging via J1772 covers a full charge overnight (8–11 hours). The car app schedules charging during cheap off-peak hours and pre-conditions the cabin while still plugged in so you don't drain range warming up.

Beyond the physical key, this car supports GM Digital Key (Ultra Cruise / Super Cruise models). Set up phone-as-key from the myGMC app: it provisions a secure credential to your phone's wallet so a tap on the door handle unlocks the car and placing the phone on the wireless charging pad authorizes ignition. You can also share temporary keys to family members (with optional speed and area limits on performance trims) directly from the app.

A few things every new owner tells us they wish they'd known on day one:

• Enable one-pedal driving in the dynamics menu — once you adapt (about 30 minutes), you'll rarely touch the brake in town and regen does the slowing.
• Pre-condition the battery before fast-charging by entering the charger in nav — the car warms the pack for full-speed charging.
• Download the brand app (myGMC) and pair it with your VIN before your first long trip — remote climate, charging/fuel-level checks, and remote lock-status save you walking back to the garage in winter.
