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.
4. Close the lid securely as illustrated with
OCandOD.
5. Operate the buttons to check the operation.
If you need assistance with replacement, it

* 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.
