8-10Do-it-yourself

Check the fluid level in the reservoir.
The fluid level should be checked when the
fluid is cold at fluid temperatures of 32 to
86ºF (0 to 30ºC). The fluid level can be
checked with the level gauge which is at-
tached to the cap. To check the fluid level,
remove the cap. The fluid level should be
between the MAX
OAand MINOBlines.
If the fluid is below the MIN
OBline, add
Genuine NISSAN E-PSF or equivalent. Re-
move the cap and fill through the opening.
WARNING
Power steering fluid is poisonous and
should be stored carefully in marked
containers out of the reach of children.
CAUTION
• DO NOT OVERFILL.
• Use of a power steering fluid other
than Genuine NISSAN E-PSF or
equivalent will prevent the power
steering system from operating
properly.
For additional information on brake fluid
specification, see “Recommended fluids/
lubricants and capacities” (P. 10-2).
WARNING
• Use only new fluid from a sealed con-
tainer. Old, inferior or contaminated
fluid may damage the brake system.
The use of improper fluids can dam-
age the brake system and affect the
vehicle's stopping ability.
• Clean the filler cap before removing.

tronic accessories that consume bat-
tery power when the engine is not run-
ning (Phone chargers, GPS, DVD
players, etc.)
2. Vehicle is not driven regularly and/or
only driven short distances. In these cases, the battery may need to
be charged to maintain battery health.
