Nissan Sentra B18 (2020-2025) Owner's Manual: Remote Engine Start

The
button is available on the NISSAN Intelligent Key when the Nissan Sentra is equipped
with the Remote Engine Start system. This convenient feature allows the engine of
the Nissan Sentra to be started from outside the vehicle, helping to pre-condition
the cabin before driving.
When the Remote Engine Start function is used, certain vehicle systems may operate differently depending on equipment and conditions:
- Vehicles equipped with a manual climate control system will resume operation using the last selected heating or cooling settings.
- Vehicles equipped with an automatic climate control system may automatically select a heating or cooling mode based on outside temperature and the interior cabin temperature of the Nissan Sentra.
Laws and regulations in some local communities may restrict or prohibit the use of the Remote Engine Start feature, or may limit the amount of time a parked engine is allowed to idle. For example, some regulations require the vehicle to remain within the driver’s line of sight, while others limit engine idling except during extremely cold conditions.
Always check and comply with local laws and regulations before using the Remote Engine Start feature on your Nissan Sentra.
Additional conditions, including environmental factors and vehicle status, may affect the operation of the Remote Engine Start system.
Other conditions may also influence the performance and communication range of the Intelligent Key transmitter.
Remote Engine Start operating range
WARNING
- To help reduce the risk of injury or death caused by unintended vehicle operation or system activation, including window entrapment or accidental door locking, never leave children, individuals requiring assistance, or pets unattended inside the Nissan Sentra. On warm days, the temperature inside a closed vehicle can rise rapidly and become life-threatening.
- Do not use the Remote Engine Start feature in enclosed or poorly ventilated spaces such as garages. Exhaust gases contain carbon monoxide, which is colorless and odorless but extremely dangerous. Inhalation can cause unconsciousness or death.
CAUTION
If the Intelligent Key battery is weak or if strong radio wave interference is present near the vehicle, the operating range of the Intelligent Key may be reduced and the Remote Engine Start function on the Nissan Sentra may not operate correctly.
The Remote Engine Start feature can only be activated when the Intelligent Key is within the specified operating range of the vehicle.
The Remote Engine Start operating range is approximately 197 ft (60 m) from the Nissan Sentra under normal conditions.
