bly.
Checking Exhaust SystemELS0021U
Check the exhaust pipes, muffler, and exhaust mounts for improper
attachment, leaks, cracks, damage, chafing, or deterioration.
Checking CVT FluidELS0021V
FLUID LEVEL CHECK
Fluid level should be checked with the fluid warmed up to 50 to 80°C (122 to 176°F).
1. Check for fluid leakage.
2. With the engine warmed up, drive the vehicle to warm up the
CVT fluid. When ambient temperature is 20°C (68°F), it takes
about 10 minutes for the CVT fluid to warm up to 50 to 80°C
(122 to 176°F).
3. Park the vehicle on a level surface and set the parking brake.
4. With engine at idle, while depressing brake pedal, move the
selector lever throughout the entire shift range and return it to
the “P” position.
5. Press the tab on the CVT fluid level gauge to release the lock
and pull out the CVT fluid level gauge from the CVT fluid charg-
ing pipe.

Only use specified NISSAN CVT fluid.

Do not overfill the CVT.
8. Install the CVT fluid level gauge to the CVT fluid charging pipe until it locks.
CAUTION:
When CVT fluid level gauge is installed into the CVT fluid charging pipe, make sure that the CVT
fluid level gauge is securely locked in place.
