Ti help with increasing fuel economy, the Honda CR-V auto idle stop automatically stops the engine when the vehicle comes to a stop. The green auto stop indicator light illuminates on the dashboard when the engine has been stopped by the system. The engine will then restart as the vehicle is about to move off and the green light goes out.
Honda CR-V Auto Stop Fault
If your Honda CR-V auto start stop system is not working, it may have developed a fault. A fault has been determined when the amber auto stop warning light and exclamation mark is displayed on the dashboard.
Honda CR-V Auto Stop Not Available
There are various conditions that the Honda CR-V must meet in order for auto stop to correctly function. If one or more of these conditions are not met, auto stop will not be available and the engine will not stop. When auto stop is unavailable for any unspecific reason, the amber auto stop warning light with a strike through it is displayed on the dashboard.
These are the conditions that auto idle stop will not activate. Depending on your version of Honda CR-V, a specific warning light may display.
- The auto idle stop button has been pressed, deactivating the system.
- The driver’s seat belt has not been secured.
- The diesel particulate filter (DPF) is being regenerated.
- Idle stop will not be available if the engine coolant temperature is too low or too high. Though this varies spending on models, it’s usually below 10°C or above 100°C. Symbol may appear.
- After the engine starts, the vehicle comes to a stop before it has reached a speed of 2 mph (3 km/h).
- The engine is started with the bonnet open. The engine will need to be restarted with the bonnet closed to activate idle stop.
- The internal temperature must not be below 5°C
- Low battery charge is a frequent issue with idle stop not activating. In frequent use of the vehicle or predominantly short trips may cause the battery to not sufficiently charge. Most start stop systems require the battery state to be charge at least 70% for they system to operate. Frequent use of air conditioning can influence battery charge state. Check if there are any firmware updates for your vehicle at your local dealer, or ask them to test the battery, battery sensor and alternator. If the battery is in low charge state, it may cause the engine to restart out from idle mode. Symbol may appear is idle stop is inhibited or engine automatically restarts due to low battery charge.
- The windscreen is being demisted.
- The steering wheel is being operated (may prevent idle stop or cause the engine to come out of idle stop).
- The climate control system is in use and the temperature outside is below -20°C or above 40°C
- The climate control temperature is set to ‘Hi’ or ‘Low’.
- There is a significant difference between the temperature inside the cabin and that set on the climate control system. Symbol may appear.
- Humidity inside the cabin is high with the climate control system activated.
- Symbol may appear.
- Stopping on a steep slope may prevent idle stop from activating. This is usually a gradient of around 10%
- If VSA (vehicle stability assistant) or ABS (see Honda CR-V dashboard warning lights) is in the process of operating, engine idle stop may be inhibited.
- Brake vacuum pressure is too low. This is a ‘booster’ system that aids driver brake pressure when applying the brake pedal.
