Over-the-Air (OTA)

Ensure the car is parked with >60% HV battery.
Connect to a strong Wi-Fi signal (cellular OTA is limited to 500MB).
Navigate to Settings → System Updates → Download.
The installation takes 25-40 minutes. The car will lock itself; do not interrupt.

After installation, the system reboots twice. Some owners report that the lane-departure warning needs manual re-calibration by driving 5 miles on a straight road.

Verification steps

Settings → About/System Info: confirm software version reads R24 (or build number matching release notes).
Test core functions: infotainment boot, phone pairing, Bluetooth audio, CarPlay/Android Auto, navigation, climate controls, charging behavior, ADAS functions (lane assist, adaptive cruise) in safe conditions.
Check for warning lights. If any persistent Warnings appear, power-cycle vehicle and re-check.

User Guide: How to Install R24

Important: Installation times can vary, but typically this update takes approximately 30–45 minutes.

Notification: You will receive an over-the-air (OTA) notification on the center console when the update is available for your VIN.
Preparation: Ensure your vehicle is parked in a safe location with the gear in 'P' (Park).
Battery Level: It is recommended to have at least 30% battery charge before starting the update to prevent the car from sleeping mid-process.
Execution:
- Tap "Download" via the connectivity menu.
- Once downloaded, select "Install Now."
- The screens will turn off and the system will reboot. Do not attempt to drive the vehicle during installation.
Completion: You will see a "Update Successful" message upon completion. You may need to re-pair your Bluetooth devices.

Installation Methods: OTA vs. Dealer

The Bad

Battery drain during OTA: Several users reported losing 4-5% of high-voltage battery charge during the installation process. This is normal but poorly communicated in the pre-update instructions.
Lost settings: The update resets some preferences (e.g., Auto Hold, Regeneration level, Ambient lighting color) to default. Owners must re-enter these.
Sporadic LTE dropouts: A minority of users (approx. 3% based on forum polls) lost cellular connectivity for 48 hours post-update, requiring a hard reset (disconnect 12V battery for 10 minutes).

2. Preparations and safety checks

Confirm exact model and VIN: record VIN and infotainment software version (Settings → About System).
Backup settings: note radio presets, navigation favorites, and paired devices. Not all updates retain user data.
Battery state: ensure 50–100% 12V battery health and main battery charge >20% (EV traction battery); connect to charge if possible.
Stable environment: park vehicle on level ground, handbrake on, engine off (if applicable). Avoid updates during storms or low-signal conditions.
Connectivity: ensure strong Wi‑Fi or cellular signal if using OTA; for USB/manual, use manufacturer-provided file only.
Time allowance: set aside 30–90 minutes. Don’t interrupt power or open doors during update unless instructed.
Read release notes: if available from manufacturer or dealer, scan to understand changes and known issues.
