Power Steering Fluid and the 2018 Toyota Avensis

For those who own or are interested in the 2018 Toyota Avensis, understanding the power steering system is quite important, especially when it comes to maintenance. A common question that pops up is whether the 2018 Avensis uses power steering fluid. After checking technical sources and manufacturer specifications, it turns out that the 2018 Toyota Avensis does not use traditional power steering fluid.

Why is that? The 2018 Toyota Avensis comes equipped with an electric power steering system, often referred to as EPS (Electric Power Steering). Unlike older systems that rely on hydraulic assistance, which uses power steering fluid, the electric system uses an electric motor to provide steering assistance. This eliminates the need for hydraulic fluid altogether.

Traditional hydraulic power steering systems require power steering fluid as the hydraulic medium to amplify the driver's input at the steering wheel and make turning easier. The fluid circulates through a pump, valves, and lines to aid steering effort. Since the 2018 Toyota Avensis uses electric power steering, there is no hydraulic pump or fluid reservoir, instead, an electric motor and sensors control the assistance directly.

This design has a few notable benefits. First, with no hydraulic fluid in the system, there is less complexity and fewer components that require regular checks and maintenance. Secondly, electric power steering is generally more fuel-efficient since it only uses power when steering assistance is needed, unlike hydraulic systems that run off the engine's power continuously. This also makes the steering feel more precise and responsive.

Because the 2018 Avensis uses electric power steering, there is no power steering fluid to check, replace, or top up. This means owners don't have to worry about leaks, fluid contamination, or scheduling power steering fluid flushes as part of routine servicing, which can save time and money over the life of the vehicle.

So, what does this mean in terms of maintenance? While traditional hydraulic power steering systems require periodic fluid inspection and replacement every 50,000 to 100,000 kilometres or so, the electric power steering system in the 2018 Toyota Avensis is mostly maintenance-free. However, it is still important to keep an eye on the overall steering performance. If steering feels unusually heavy, noisy, or if warning lights appear on the instrument panel, it's a good reason to have the system inspected by a qualified Toyota technician.

Some other points worth noting for owners include:

• If the vehicle is involved in an accident or the steering components are damaged, it is essential to perform a diagnostic check on the EPS system to ensure everything is functioning correctly.
• Though the electric power steering system typically lasts the lifetime of the vehicle, the EPS motor and sensors might wear out or develop faults over time, requiring replacement or repair.
• Software updates or calibration may sometimes be necessary during servicing to maintain optimal steering feel and performance, especially after wheel alignment or suspension repairs.

In short, the absence of power steering fluid in the 2018 Toyota Avensis reflects a shift towards more modern, efficient steering technology. It simplifies regular vehicle maintenance by removing the need for fluid checks and replacements, while also delivering improved fuel economy and handling characteristics.
