BATTERY REPLACEMENT
8-26Do-it-yourself

Replace the battery in the Intelligent Key as
follows:
1. Remove the mechanical key from theIntelligent Key.
2. Insert a small flathead screwdriver
OA
into the slitOBof the corner and twist it
to separate the upper part from the
lower part. Place a cloth over the screw-
driver to protect the casing. 3. Replace the battery with a new one.
Recommended battery: CR2032 or
equivalent.• Do not touch the internal circuit and electric terminals as doing so could
cause a malfunction.
• Hold the battery by the edges. Holding the battery across the contact points
will seriously deplete the storage
capacity.
• Make sure that the + side faces the bottom of the lower part.

* Maintenance items and intervals with “*”
are recommended by NISSAN for reliable
vehicle operation. The owner need not per-
form such maintenance in order to main-
tain the emission warranty or manufac-
turer recall liability. Other maintenance
items and intervals are required.
(1) If operating mainly in dusty conditions,
more frequent maintenance may be
required.
(2) Request a NISSAN dealer to inspect the
fluid deterioration data using a CONSULT. If
the deterioration data is more than 77000,
replace the AT fluid. (3) If using under severe conditions such as
towing a trailer, using a car-top carrier, or
driving on rough or muddy roads, change
(not just inspect) oil at every 30,000 miles
(48,000 km) or 24 months. NISSAN recom-
mends using Genuine NISSAN Matic P au-
tomatic transmission fluid. Using auto-
matic transmission fluid that is not
equivalent to Genuine NISSAN Matic P may
damage the transmission or impact trans-
mission durability. Damage caused by the
use of fluid other than as recommended is
not covered under the NISSAN New Vehicle
Limited Warranty.
(4) The propeller shaf t should be re-
greased af ter being immersed in water.
