As winter arrives, many drivers worry about cold starts and battery drain.
To help owners, Dongfeng Nissan has released a winter driving guide for the Nissan N7.
The guide focuses on why battery power drops in low temperatures.
It also explains how Nissan N7 users can start the car easily and avoid “no-start” situations in daily life.
Firstly, cold weather slows the chemical reaction inside the battery.
When temperatures fall sharply, battery capacity and output both decrease.
As a result, the battery may not provide enough power for starting.
Drivers then feel that the car becomes harder to wake up on freezing mornings.

Thirdly, the parking environment is very important.
When the N7 stays outdoors in strong wind and low temperatures, performance drops faster.
Long-term parking in open, freezing areas speeds up aging and power loss.
Under these conditions, the car may show warning messages or difficulty starting.
The guide also reminds owners about one key limit.
When the outside temperature is at or below –10°C, the N7 automatic battery replenishment function pauses.
In this range, there is a higher risk of battery drain, especially if the car sits still for several days.
To control these risks, Dongfeng Nissan recommends actions in two areas.
Owners should focus on daily maintenance and on start-up and pre-heating skills.
Together, these measures help “lock in” battery power and keep the N7 ready to go.
Firstly, owners should check the battery during routine service.
Dealers can use a battery tester to measure state of health and charge level.
If test results show low charge or capacity loss, the guide suggests timely recharging or replacement.
Early action helps avoid sudden failure on cold mornings.
Secondly, the guide advises parking in warm environments whenever possible.
A covered garage or underground parking lot helps protect the battery from extreme cold.
By reducing long exposure to freezing air, owners can slow performance decay and extend service life.
Thirdly, N7 owners should build careful power-usage habits.
Before leaving the vehicle, they should check that lights, audio and other devices are turned off.
This step stops the car from quietly consuming power while parked.
Before a winter trip, drivers can also use the mobile app to pre-heat the car.
They may choose to remotely start the N7 so the main power system can replenish the battery.
With this method, the vehicle already has stronger power reserves when the driver gets in.
Thus, it is easier to start and drive away, even after a cold night.
When the weather is very cold, drivers should avoid repeated short attempts to start the car.
Instead, they should follow the instructions in the owner’s manual and wait for system checks to finish.
If the N7 has been parked outside in sub-zero conditions for a long time, pre-heating through the app is recommended.
This step helps stabilize the battery and cabin temperature before driving.
By combining correct start-up operations with the daily maintenance steps above, most winter “no-start” issues can be avoided.
Dongfeng Nissan emphasizes that scientific maintenance and good habits are the best protection for the N7 in winter.
With proper battery checks, warmer parking, wise power use and remote pre-heating, owners can drive with peace of mind.
The N7 winter guide aims to make the vehicle a reliable partner through the cold season, not a source of anxiety.
With these tips, N7 drivers can cross the winter safely and enjoy worry-free electric travel.
