The Complete Overview of Remote Starting a Subaru Forester
Remote starting a Subaru Forester isn’t a one-size-fits-all process. It depends on the model year, trim level, and whether you’re leveraging factory-installed features or an aftermarket solution. Subaru has gradually expanded its remote start capabilities over the years, with newer models incorporating keyless entry systems that allow for remote ignition via a smartphone app or dedicated key fob. For example, the 2021 and newer Foresters with the StarLink® Telematics system can be started remotely through the Subaru View app, provided the vehicle is equipped with the necessary hardware. Older models, particularly those predating 2018, may require third-party add-ons like the Viper® SmartStart or Compustar® Remote Start systems, which plug into the vehicle’s OBD-II port or wiring harness.
The key to successfully remote starting your Subaru Forester lies in understanding your vehicle’s compatibility. Subaru’s official stance is that remote start functionality is primarily available on higher trims or as part of optional packages. For instance, the 2023 Forester Limited and Touring trims often include the StarLink system, which supports remote start as part of its suite of connected services. However, even if your Forester lacks built-in remote start, aftermarket solutions can bridge the gap—though installation quality and reliability vary widely. It’s worth noting that Subaru’s official policy discourages unauthorized modifications that could void warranties, so any aftermarket installation should be handled by a certified technician familiar with Subaru’s electrical systems.
Historical Background and Evolution
The concept of remote starting vehicles dates back to the 1980s, when car alarms with basic remote start functions began appearing in luxury models. However, it wasn’t until the 2000s that mainstream automakers like Subaru began integrating these features into their vehicles. Early implementations were clunky, often requiring a separate key fob with limited range. Subaru’s approach evolved alongside technological advancements. By the mid-2010s, the brand started offering keyless entry systems that paired with dedicated key fobs, allowing drivers to lock, unlock, and—on select models—start the vehicle remotely. The introduction of StarLink Telematics in 2018 marked a turning point, as it enabled app-based remote start, paving the way for a more connected driving experience.
Today, the ability to remote start a Subaru Forester is tied to Subaru’s broader strategy of blending traditional reliability with modern connectivity. The shift toward app-based controls reflects a broader industry trend, where automakers are prioritizing seamless integration between vehicles and smartphones. For Subaru, this means leveraging its existing infrastructure—such as the EyeSight Driver Assist Technology—to enhance remote functionality. For example, some newer Foresters can now receive remote start commands through the Subaru View app, which also provides vehicle diagnostics, trip planning, and even emergency assistance. This evolution underscores why understanding your Forester’s model year and trim is critical; a 2016 Forester may not support the same features as a 2024 model, even if they share the same body style.
Core Mechanisms: How It Works
At its core, remote starting a Subaru Forester relies on a combination of radio frequency (RF) signals, Bluetooth connectivity, or a vehicle’s onboard computer system to execute the start command. In factory-installed systems, such as those found in StarLink-equipped Foresters, the process begins when the driver sends a signal through the Subaru View app. This signal is encrypted and transmitted to the vehicle’s telematics control unit (TCU), which then relays the command to the engine control module (ECM). The ECM, in turn, initiates the start sequence, provided the vehicle meets safety conditions (e.g., the transmission is in Park, the brakes are engaged, and the battery voltage is sufficient).
Aftermarket solutions, on the other hand, typically use a dedicated device that plugs into the Forester’s OBD-II port or interfaces with the vehicle’s wiring harness. These devices—such as the Viper SmartStart or Compustar Remote Start—emit an RF signal when activated, which the vehicle’s alarm or immobilizer system interprets as a valid command. The challenge here lies in ensuring the device is compatible with Subaru’s security protocols; some aftermarket systems may trigger the vehicle’s anti-theft system if not properly configured. Additionally, the range of these devices is limited (usually 30–100 feet), and obstacles like thick walls or metal structures can weaken the signal. This is why many owners opt for Bluetooth-enabled aftermarket systems, which pair directly with a smartphone app for more reliable control.
Key Benefits and Crucial Impact
The advantages of remote starting your Subaru Forester extend beyond mere convenience. For one, it enhances vehicle security by allowing you to start the engine and set the alarm if you suspect unauthorized access. In extreme weather conditions—whether a blizzard or a heatwave—remote start ensures your Forester is ready to drive the moment you step outside, reducing wait times and improving comfort. It also contributes to fuel efficiency by allowing the engine to warm up or cool down gradually, rather than idling excessively once you’re inside. For families or those with pets, this means less time spent waiting for the cabin to reach a comfortable temperature, making errands and commutes more efficient.
Beyond practicality, remote start functionality aligns with modern lifestyle expectations. In an age where smart home devices and voice assistants are ubiquitous, the ability to control your vehicle from your pocket feels like a natural extension of that ecosystem. For Subaru owners, this integration is particularly smooth thanks to the Subaru View app, which consolidates remote start with other connected services. However, the impact isn’t just personal—it’s also environmental. By optimizing engine warm-up times, remote start can reduce unnecessary idling, which is a known contributor to emissions. When you consider that millions of vehicles are started remotely every day, the cumulative effect on air quality and fuel consumption becomes significant.
