What does L mean in Subaru Forester?
In Subaru Forester models equipped with the Lineartronic CVT, L stands for Low—a low-range setting that keeps the engine RPM higher at low speeds to deliver more torque and to provide stronger engine braking on hills, snow, and rough terrain.
Unlike a traditional manual gearbox, L is not a shift into a specific first gear; it is a fixed low ratio within the CVT that is engaged by selecting L. This helps with control in difficult conditions but reduces fuel efficiency if used on normal highways.
Understanding L in the Forester's CVT
The Forester's CVT uses a belt-and-pulley system that normally varies ratios for efficiency. When you select L, the transmission locks into a lower ratio, which raises engine RPM at a given speed. This provides more immediate throttle response and enables engine braking when braking is light. The effect is most noticeable at low speeds and during slow climbs or descents.
When to use L
Common scenarios where L is helpful include:
- Steep climbs or heavy loads where more torque at low speed improves traction and control.
- Descending hills to use engine braking and reduce brake wear.
- Slick surfaces such as snow or ice where steady torque helps maintain grip.
Note: Use L selectively. It increases engine RPM and reduces fuel efficiency, so switch back to D when normal highway driving resumes.
How L differs from other modes
In D (Drive) the CVT optimizes for efficiency and smoothness, varying ratios continuously. In L, the system stays in a lower ratio for more torque and braking. Some models also offer S (Sport) for quicker throttle response, or X-Mode for enhanced traction in off-road conditions; L can complement these modes depending on the year and trim.
Practical tips
Tips to use L effectively:
- Engage L before you reach the steep grade or slippery surface; you’ll have better control coming from a stop or slow speed.
- Avoid prolonged use of L on dry, flat highways as it reduces efficiency and increases engine wear.
- Combine L with careful throttle control; power should come smoothly to prevent wheel spin.
Switch back to D when you no longer need the extra torque or engine braking to resume normal, fuel-efficient driving.
Summary
In summary, L on a Subaru Forester’s CVT stands for Low, a low-range mode that keeps the engine in a higher RPM band to deliver more torque at low speeds and to provide engine braking on descents or in slippery conditions. Use it in challenging driving situations, and return to Drive for normal conditions to optimize fuel efficiency and wear.
