This document is a maintenance manual for 2022 BMW i4 and iX vehicles, outlining the recommended service procedures, intervals, and coverage under the BMW Ultimate Care Scheduled Maintenance Program.
Function Description:
The manual serves as a comprehensive guide for owners and authorized BMW centers to ensure the proper maintenance and reliability of 2022 BMW i4 and iX vehicles. It details the Condition Based Service (CBS) system, which dynamically monitors vehicle maintenance needs based on sensors, algorithms, elapsed time, and driving profile. This system adapts maintenance task intervals to actual operating conditions, moving beyond conventional fixed time or mileage-based schedules. The CBS system helps forecast when specific maintenance tasks are required and alerts the driver accordingly. The manual also provides information on the BMW Ultimate Care Scheduled Maintenance Program, which covers specific factory-recommended maintenance services for eligible vehicles.
Important Technical Specifications:
The maintenance intervals are determined by the Condition Based Service (CBS) system, which uses vehicle sensors and algorithms. This system monitors various parameters including:
- Vehicle check: Date and miles.
- Brake pads: Front and rear (miles remaining). The status is observable when approximately 2,000 miles or less remain before service.
- Brake fluid: Date.
- Cabin microfilter(s): Identified as needing service in conjunction with a specific Vehicle Check service task (service counter number).
- Remote control key battery: Covered under maintenance services.
- Ventilation microfilter: Replaced every 2 years based on vehicle production date or in connection with a scheduled vehicle check.
Long-term rated fluids and oils are factory-filled and generally only require replacement when repairs are being performed, unless otherwise noted. These include the electrical machine cooling system (antifreeze/coolant) and automatic transmission fluid.
Usage Features:
The vehicle's iDrive Control Display allows the driver to access current service status and maintenance requirements.
