How do you enable the blind spot information system on an Acura?
To enable the Blind Spot Information System (BSI) on an Acura, use the dedicated switch if your model has one, or enable it through the vehicle’s Settings menu. In most newer Acuras, BSI is active by default when AcuraWatch or the Safety Suite is enabled.
Understanding the Blind Spot Information System
The Blind Spot Information System helps alert you to vehicles in the areas alongside your car that you may not see in your mirrors. It typically uses radar sensors mounted near the rear of the vehicle and provides visual cues on the exterior mirrors, and sometimes audible alerts, to warn you before changing lanes. The system is often part of AcuraWatch or the Safety Suite and works at speeds where lane-change decisions are common.
Where to Find the Controls
Control locations can vary by model year and trim. The two most common options are a physical BSI toggle switch and in-vehicle settings accessed through the instrument cluster or touchscreen/menu system.
Physical switch (if equipped)
If your Acura has a dedicated Blind Spot Information switch, use it to turn BSI on or off. The switch is usually located on the lower dash near the steering column or close to the hood release lever. Look for a button labeled with a blind-spot symbol or the letters “BSI.”
- Locate the BSI switch on the lower-left dash area or near the steering column.
- Press the switch once to turn BSI ON; you may see a light or icon indicate it is active on the mirror or instrument cluster.
- Press the switch again to turn BSI OFF.
Note: If you don’t see a dedicated BSI switch on your model, proceed to the in-menu method described below.
In-vehicle settings (no physical switch)
Many Acura models allow you to enable or disable BSI through the vehicle’s settings menu using the steering wheel controls.
- Access the Driver Information Interface or central infotainment display from the steering wheel controls.
- Navigate to Settings or Vehicle Settings.
- Select Blind Spot Information (BSI) or a similar option under Safety or Driver Assist.
- Toggle BSI ON to activate it, or OFF to deactivate.
- Confirm the change and test by driving slowly and checking for the mirror indicators when another vehicle enters your blind spot.
If your model shows BSI in the settings but you don’t feel a change, ensure AcuraWatch or the Safety Suite is also active, as BSI often relies on those features being enabled.
Model-Specific Notes
Control methods can differ by model and year. Some trims include BSI as a standard feature with a physical toggle, while others rely entirely on the vehicle’s Settings menu. If you’re unsure which method your car uses, consult the owner’s manual for your exact year and trim or contact a local Acura dealer for guidance.
Tips and Limitations
BSI is a helpful aid, but it has limitations. Use it as a supplement to mirrors and head checks, not a replacement. Sensor performance can be affected by weather, vehicle type, or road conditions, and some vehicles—such as motorcycles or very small cars—may not be detected as consistently. Always verify the blind spots visually before changing lanes.
- BSI relies on radar sensors and may not detect all nearby vehicles in every scenario.
- Performance can be impacted by rain, snow, or when the sensors are blocked or dirty.
- Always check mirrors and shoulder checks before changing lanes, even if BSI is active.
Regularly clean the side mirrors and camera/sensor areas to maintain sensor effectiveness, and ensure the system and related safety features are kept up to date with any software updates from Acura.
Summary
Enabling the Blind Spot Information System on an Acura typically involves a simple toggle—either a physical BSI switch on the dash or an in-menu setting accessed via the steering wheel controls. If your model includes AcuraWatch or a Safety Suite, ensure those features are active, as BSI often relies on them. Always use visual checks in addition to BSI alerts for safe lane changes. If in doubt about your specific model/year, refer to the owner’s manual or contact an Acura dealership for precise instructions.
