Nissan Sentra Dashboard Warning Lights
Now we’ll take a look at the Nissan Sentra dashboard warning lights that may come on when driving. It’s advisable to deal with amber / yellow warning lights as soon as possible and red warning lights immediately. Red warning lights are the most urgent and can potentially result in vehicle damage and/or risk to vehicle occupant safety.
Symbol Name: ABS
Description: This is the Nissan Sentra anti-lock braking system (ABS) warning light. The symbol may also be displayed as . If the light illuminates while driving, it indicates an ABS malfunction. ABS prevents the wheels from locking during harsh braking, which in turn allows for greater control of the vehicle.
What to Do: If an ABS malfunction occurs, the anti-lock function is no longer operational. The brake system
continues to operate normally but without anti-lock assistance. Have system checked as soon as possible. The most frequent cause of fault is due to a malfunctioning wheel speed sensor.
Symbol Name: AEB
Description: The Nissan Sentra Automatic Emergency Braking system (AEB) aids the driver when a risk of a forward collision with a vehicle ahead in same lane. To calculate distances, AEB uses a radar sensor located behind the lower grille of the front bumper.
If a collision risk is detected, the system will provide a warning to the driver by a warning light and audible alarm. If the brakes are applied quickly and forcefully after the warning, but AEB still detects a potential collision, the system automatically increases braking force. AEB can be manually turned off in the Setting / Driving Aids menu.
What to Do: A warning light illuminates if the system has been manually switched off. If a warning light comes on but the system has not been switched off, a fault has been detected. Ensure the location of the sensors is clean.

What to Do: Stop as soon as possible and check tyres pressures and inflate in accordance with the tire and loading label located inside the driver door (B-pillar). After inflation, the warning light will not automatically go out. To do this, driver at 16 mph (25 km/h) or more to activate the TPMS.

- avoid hard acceleration or deceleration.
- avoid steep uphill driving.
- if possible, reduce the amount of cargo being towed.
Steady: Check the fuel filler cap is securely fitted. After a few trips, the light should go out. If the fuel filler cap is not the problem, there’s a fault with the emissions control program. This is not urgent but may result in increased fuel consumption.
Symbol Name: OD

Symbol Name: SERVICE
Description: The Nissan Sentra SERVICE ENGINE SOON warning light is an alternative to the malfunction indicator light as seen above.
What to Do: Sensors in the vehicle have detected fault. Faults are usually related to emissions or possible a loose gas cap. If the light begins blinking, have vehicle checked immediately.
