OUTLINE

1. The 3ZR-FAE engine is an in-line 4-cylinder, 2.0-liter, 16-valve DOHC engine. This engine uses the VALVEMATIC, Dual Variable Valve Timing-intelligent (Dual VVT-i) system, Acoustic Control Induction System (ACIS), Direct Ignition System (DIS) and Electronic Throttle Control System-intelligent (ETCS-i). They have been developed to achieve high performance and fuel economy, and to reduce exhaust emissions.

• *1: Weight shows the figure with oil and engine coolant fully filled.

• *2: Premium unleaded gasoline with a research octane number 95 or higher required for optimum engine performance. If 95 octane cannot be obtained, you may use unleaded gasoline with a research octane number as low as 91. Use of unleaded fuel with a research octane number lower than 95 may result in engine knocking and significantly reduced performance. Persistent knocking can lead to engine damage and should be corrected by refueling with higher octane unleaded gasoline.
