Hacks & Secrets

Hidden features, easter eggs, and tricks you won't find in the manual — from real owners.

  • Gulf-Specific

    Pre-cool from the app at home

    Open the car app 10 min before leaving. Cabin cools, battery pre-conditions for charging. Saves time, max comfort in 50° summers.

  • Money Saver

    Schedule charging at off-peak rates

    In countries with time-of-use rates (UAE Slab 1), schedule 23:00-06:00 to save 20-40% on your electricity bill.

  • Comfort

    Camp Mode for sleeping or waiting

    Park in P, enable Camp Mode from menu or voice command. AC stays on, screens dim. Uses only ~1 kWh/hour.

  • Performance

    Max regen for less brake wear

    Set regen to highest (One-Pedal or High). Cuts brake wear 60%+ and adds 5-10% range in city traffic.

  • Money Saver

    Bump tire pressure +0.2 bar in summer

    A small bump (~0.2 bar above recommended) reduces rolling resistance and adds 3-5% range. Also a heat-safety win.
