Do-it-yourself -> Maintenance precautions for Your Nissan Qashqai SUV 2020

MAINTENANCE PRECAUTIONS  
When performing any inspection or main-  
tenance work on your vehicle, always  
take care to prevent serious accidental  
injury to yourself or damage to the  
vehicle. The following are general precau-  
tions which should be closely observed.  
.
.
Always wear eye protection  
whenever you work on your ve-  
hicle.  
If you must run the engine in an  
enclosed space such as a garage,  
be sure there is proper ventilation  
for exhaust gases to escape.  
Never get under the vehicle while  
it is supported only by a jack. If it  
is necessary to work under the  
vehicle, support it with safety  
stands.  
.
.
.
On gasoline engine models with  
the Multiport Fuel Injection (MFI)  
system, the fuel filter and fuel  
lines should be serviced because  
the fuel lines are under high  
pressure even when the engine  
is turned off. It is recommended  
that you visit a NISSAN dealer for  
this service.  
Your vehicle is equipped with an  
automatic engine cooling fan. It  
may come on at any time without  
warning, even if the ignition  
switch is in the OFF position and  
the engine is not running. To  
avoid injury, always disconnect  
the negative battery cable before  
working near the fan.  
WARNING  
.
.
.
Park the vehicle on a level sur-  
face, apply the parking brake  
securely and block the wheels to  
prevent the vehicle from moving.  
Move the shift lever to the P  
(Park) position (CVT model) or  
the shift lever to the N (Neutral)  
position (MT model).  
Because the fuel lines are under  
high pressure even when the  
engine is off, it is recommended  
you visit  
a NISSAN dealer for  
service of the fuel filter or fuel  
lines.  
.
.
Be sure the ignition switch is in  
the OFF or LOCK position when  
performing any parts replace-  
ment or repairs.  
If you must work with the engine  
running, keep your hands, cloth-  
ing, hair and tools away from  
moving fans, belts and any other  
moving parts.  
Avoid direct contact with used  
engine oil and coolant. Impro-  
perly disposed engine oil, engine  
coolant, and/or other vehicle  
fluids can hurt the environment.  
Always conform to local regula-  
tions for disposal of vehicle fluids.  
.
.
Do not work under the hood while  
the engine is hot. Always turn off  
the engine and wait until it cools  
down.  
If you must work with the engine  
running, keep your hands, cloth-
