Oil filter tightening torque:11 to 15 ft-lb
(14.7 to 20.5 N·m)
8. Clean and re-install the drain plug with a new washer. Securely tighten the
drain plug with a wrench. Drain plug tightening torque:
22 to 29 ft-lb
(29 to 39 N·m)
Do not use excessive force.
9. Refill the engine with the recommended oil through the oil filler opening, and
install the oil filler cap securely.
See “Capacities and recommended
fuel/lubricants” (P.9-2) for drain and
refill capacity. The drain and refill
capacity depends on the oil tempera-
ture and drain time. Use these specifi-
cations for reference only. Always use
the dipstick to determine the proper
amount of oil in the engine.
10. Start the engine and check for leakage around the drain plug and the oil filter.
Correct as required.
11. Turn the engine off and wait more than 15 minutes. Check the oil level with the
dipstick. Add engine oil if necessary.

Check the fluid level in the reservoir.
The fluid level should be checked with the
engine off using the HOT range (
*1: HOT
MAX.,
*2: HOT MIN.) at fluid temperatures
of 122 to 1768F (50 to 808C) or using the
COLD range (
*3: COLD MAX.,*4: COLD
MIN.) at fluid temperatures of 32 to 868F (0
to 308C).
If the fluid is below the MIN line, add
Genuine NISSAN PSF or equivalent. Re-
move the cap and fill through the opening.
CAUTION
. Do not overfill.
. Use Genuine NISSAN PSF or equivalent.

tion, see “Capacities and recommended
fuel/lubricants” (P.9-2) of this manual.
WARNING
.Use only new fluid from a sealed
container. Old, inferior or contaminated
fluid may damage the brake system. The
use of improper fluids can damage the
brake system and affect the vehicle’s
stopping ability.
. Be sure to clean the filler cap before
removing.
. Brake fluid is poisonous and should be
stored carefully in marked containers out
of the reach of children.

coolant for window washer solution. This
may result in damage to the paint.
. Do not fill the window washer reservoir
tank with washer fluid concentrates at
full strength. Some methyl alcohol
based washer fluid concentrates may
permanently stain the grille if spilled
while filling the window washer reser-
voir tank.

GUID-8579C36F-FFF9-4B84-AE07-383645D32C18.Keep the battery surface clean and dry.
Clean the battery with a solution of
baking soda and water.
. Make certain the terminal connections
are clean and securely tightened.
. If the vehicle is not to be used for 30
days or longer, disconnect the negative
(−) battery terminal cable to prevent
discharging it.
NOTE:
Care should be taken to avoid situations
that can lead to potential battery dis-
charge and potential no-start conditions
such as:
1. Installation or extended use of electro-
nic accessories that consume battery
power when the engine is not running
(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.
CAUTION
When the battery cable is removed from the
battery terminal, do not close either of front doors. The automatic window adjusting
function will not work, and the side roof
panel may be damaged.
To disconnect the negative (−) battery
terminal, perform the procedure in the
following order. Otherwise, the window
and the side roof panel may contact and
be damaged.
1. Close the windows.
2. Open the hood.
3. Close and lock all the doors.
4.
Disconnect the negative (−) battery
terminal.
5. Securely close the hood.
To connect the negative (−) battery term-
inal, perform the procedure in the follow-
ing order. Otherwise, the window and the
side roof panel may contact and be
damaged.
1. Unlock and open the driver side door. Do not close the door.
2. Open the hood.

1. Remove the cell plugs*A.
2. Add distilled water up to the UPPER LEVEL
*1line.
If the side of the battery is not clear,
check the distilled water level by
looking directly above the cell; the
condition
*1indicates OK and the
condition
*2needs more to be added.
3. Tighten cell plugs
*A.
Vehicles operated in high temperatures or
under severe conditions require frequent
checks of the battery fluid level.
JUMP STARTINGGUID-06B974E0-9B09-4316-BF6D-083DE94FA734If jump starting is necessary, see “Jump
starting” (P.6-13). If the engine does not
start by jump starting, the battery may
have to be replaced. Contact an INFINITI
retailer.
GUID-ACEB8038-7B64-4F43-B2D3-031914EC39FA
CAUTION
. Do not ground accessories directly to the
battery terminal. Doing so will bypass
the variable voltage control system and
the vehicle battery may not charge
completely.
. Use electrical accessories with the en-
gine running to avoid discharging the
vehicle battery.
The variable voltage control system mea-
sures the amount of electrical discharge
from the battery and controls voltage
generated by the generator.

wipe the inside of the air cleaner housing
and the cover with a damp cloth.
WARNING
.Operating the engine with the air
cleaner removed can cause you or others
to be burned. The air cleaner not only
cleans the air, it stops flame if the
engine backfires. If it is not there, and
the engine backfires, you could be
burned. Do not drive with the air cleaner
removed, and be careful when working
on the engine with the air cleaner
removed.
. Never pour fuel into the throttle body or
attempt to start the engine with the air
cleaner removed. Doing so could result
in serious injury.

CLEANINGGUID-724353EB-B235-4CC1-A539-18CF071AE36CIf your windshield is not clear after using
the windshield washer or if a wiper blade
chatters when running, wax or other
material may be on the blade or wind-
shield.
Clean the outside of the windshield with a
washer solution or a mild detergent. Your
windshield is clean if beads do not form
when rinsing with clear water.
Clean each blade by wiping it with a cloth
soaked in a washer solution or a mild
detergent. Then rinse the blade with clear
water. If your windshield is still not clear
after cleaning the blades and using the
wiper, replace the blades.
CAUTION
Worn windshield wiper blades can damage
the windshield and impair driver vision.

the brakes checked by an INFINITI retailer.
SELF-ADJUSTING BRAKESGUID-B60773EA-835E-45EF-8459-943C453A3E2FYour vehicle is equipped with self-adjust-
ing brakes.
The disc-type brakes self-adjust every time
the brake pedal is applied.
WARNING
See an INFINITI retailer for a brake system
check if the brake pedal height does not
return to normal.
BRAKE PAD WEAR WARNINGGUID-3EBC0D64-F1B6-4853-8B16-7707AECD26FAThe disc brake pads have audible wear
warnings. When a brake pad requires
replacement, it will make a high pitched
scraping sound when the vehicle is in
motion. This scraping sound will first occur
only when the brake pedal is depressed.
After more wear of the brake pad, the
sound will always be heard even if the
brake pedal is not depressed. Have the
brakes checked as soon as possible if the
wear warning sound is heard.
Under some driving or climate conditions,occasional brake squeak, squeal or other
noise may be heard. Occasional brake
noise during light to moderate stops is
normal and does not affect the function or
performance of the brake system.
Proper brake inspection intervals should
be followed.
For additional information,
see the maintenance log section of your
“INFINITI Service and Maintenance Guide”.
