• Engine Oil Capacity: The N55 engine has a basic oil capacity of 6.5 liters with filter .
• Brake Fluid: BMW recommends changing the brake fluid every 2 years . The vehicle requires DOT4 specification brake fluid .
• Coolant: Use BMW-approved coolant only. For vehicles not using HT-12 Anti-Corrosion Agent, use approved concentrate mixed only with distilled water .

Understanding BMW's Condition Based Service (CBS) System

The 2014 BMW 335i xDrive Gran Turismo is equipped with the Condition Based Service (CBS) system. Sensors and special algorithms take into account the driving conditions of your vehicle to recognize maintenance requirements. The system makes it possible to adapt the amount of maintenance corresponding to your user profile .

Key CBS Features:

• Sensors and algorithms monitor your driving conditions to determine when service is needed .
• Service requirements can be displayed on the Control Display .
• Information on required maintenance is continuously stored in your remote control key .
• For major periodic service, BMW recommends this be done every 2 years or after 30,000 kilometers .

Storage Periods: Storage periods during which the vehicle battery was disconnected are not taken into account by the CBS system . If this occurs, have a service center update time-dependent maintenance procedures such as checking brake fluid .
