Toyota Previa (2009 – 2012) – fuse and relay box diagram

Year of production: 2009, 2010, 2011, 2011, 2012

The Toyota Previa is a versatile and spacious minivan, also known as an MPV (multi-purpose vehicle), that has been sold globally under different names. In some markets, like Australia, it was sold as the Toyota Tarago, while in others it retained the Previa name. It is renowned for its futuristic design, reliability, and practical features, making it a popular choice for families and commercial users alike.

Key Features of the Toyota Previa:

1.Unique Design: The Previa had a distinctive egg-shaped design, especially in its earlier generations, which made it stand out among other minivans. The rounded aerodynamic body contributed to better fuel efficiency and reduced drag.

2.Seating Capacity: Depending on the market and configuration, the Previa typically offered seating for 7 to 8 passengers, making it a spacious option for families.

3.Mid-Engine Layout: One of the most unique aspects of the first-generation Previa was its mid-engine design. The engine was located under the front seats, which allowed for better weight distribution but made maintenance slightly more challenging.

4.All-Wheel Drive (AWD): Some versions of the Previa were available with all-wheel drive, enhancing traction and making it suitable for a variety of driving conditions, including rough terrain or snow.

5.Sliding Doors: The Previa featured sliding rear doors for easier passenger entry and exit, especially in tight parking spaces.

6.Flexible Interior: With foldable or removable rear seats, the Previa was designed to offer flexible space for both passengers and cargo.

Generations:

1.First Generation (1990–1999):

•This model had a very unconventional design with a mid-engine layout. The engine was mounted underneath the front seats, and it featured rear-wheel drive or optional all-wheel drive.

•Engine options included a 2.4-liter inline-4 engine and later models offered supercharged variants for more power.

•The Previa was known for its durability and spacious interior, despite its somewhat unconventional engine placement.

2.Second Generation (2000–2006):

•The second-generation Previa featured a more traditional front-engine, front-wheel-drive layout.

•It was available with a range of engines, including more fuel-efficient options. In some markets, it came with a V6 engine.

•The design was more streamlined and modern, with improved safety features and more advanced technology in the interior.

•Toyota focused on comfort and refinement, making it more family-friendly.

3.Third Generation (2006–2019):

•This generation offered even more refinement in terms of luxury, technology, and performance.

•It came with advanced features like dual-zone climate control, premium audio systems, and even hybrid variants in some regions.

•By this generation, the Previa was primarily marketed in Asia, while markets like North America received the Toyota Sienna as the main minivan option.

Previa Hybrid:

In the later years, Toyota introduced a hybrid version of the Previa, particularly in the Asian markets. It featured Toyota’s Hybrid Synergy Drive, combining a gasoline engine with an electric motor to improve fuel efficiency, making it an eco-friendlier option for larger families.

Successors:

In many regions, the Toyota Previa was phased out or replaced by other models, such as the Toyota Alphard, Toyota Estima, or the Toyota Sienna (in North America). Despite this, the Previa remains a memorable model due to its distinctive design and practicality.

The Previa is still favored in the used car market for those looking for a reliable, spacious vehicle with Toyota’s legendary durability.
