When driving in areas using road salt or other
corrosive materials, check lubrication fre-
quently.
Lights*:Clean the headlights on a regular
basis. Make sure that the headlights, stop
lights, tail lights, turn signal lights, and other
lights are all operating properly and installed
securely. Also check headlight aim.
Road wheel nuts (lug nuts)*: When checking the
tires, make sure no wheel nuts are missing, and
check for any loose wheel nuts. Tighten if
necessary.
Tire rotation*: Tires should be rotated every
7,500 miles (12,000 km). If your vehicle is
equipped with different sized tires in the front
and rear, tires cannot be rotated.
Tires*: Check the pressure with a gauge often
and always prior to long distance trips. If nec-
essary, adjust the pressure in all tires, includ-
ing the spare, to the pressure specified. Check
carefully for damage, cuts or excessive wear.
Tire Pressure Monitoring System (TPMS) trans-
mitter components: Replace the TPMS transmit-
ter grommet seal, valve core and cap when the
tires are replaced due to wear or age.
Tire, wheel alignment and balance: If the vehicle
should pull to either side while driving on a straight and level road, or if you detect uneven
or abnormal tire wear, there may be a need for
wheel alignment.
If the steering wheel or seat vibrates at normal
highway speeds, wheel balancing may be
needed.
For additional information regarding tires, refer
to “Important Tire Safety Information” (US) or
“Tire Safety Information” (Canada) in the
INFINITI Warranty Information Booklet.
Windshield:
Clean the windshield on a regular
basis. Check the windshield at least every six
months for cracks or other damage. Have a
damaged windshield repaired by a qualified
repair facility.
Windshield wiper blades*: Check for cracks or
wear if they do not wipe properly.
Inside the vehicle
The maintenance items listed here should be
checked on a regular basis, such as when
performing periodic maintenance, cleaning the
vehicle, etc.
Accelerator pedal: Check the pedal for smooth
operation and make sure the pedal does not
catch or require uneven effort. Keep the floor
mat away from the pedal. Automatic transmission P (Park) mechanism:
On
a fairly steep hill, check that your vehicle is held
securely with the selector lever in the P (Park)
position without applying any brakes.
Brake pedal: Check the pedal for smooth opera-
tion. If the brake pedal suddenly goes down
further than normal, the pedal feels spongy or
the vehicle seems to take longer to stop, see an
INFINITI retailer immediately. Keep the floor mat
away from the pedal.
Brakes: Check that the brakes do not pull the
vehicle to one side when applied.
Parking brake: Check the parking brake opera-
tion regularly. The vehicle should be securely
held on a fairly steep hill with only the parking
brake applied. If the parking brake needs ad-
justed, see an INFINITI retailer.
Seat belts: Check that all parts of the seat belt
system (for example, buckles, anchors, adjuster
and retractors) operate properly and smoothly,
and are installed securely. Check the belt web-
bing for cuts, fraying, wear or damage.
Seats: Check seat position controls such as
seat adjusters, seatback recliner, etc. to ensure
they operate smoothly and that all latches lock
securely in every position. Check that the head
Maintenance and do-it-yourself8-3

When performing any inspection or mainte-
nance work on your vehicle, always take care to
prevent serious accidental injury to yourself or
damage to the vehicle. The following are gen-
eral precautions which should be closely ob-
served.
WARNING
●Park the vehicle on a level surface, apply the
parking brake securely and block the wheels
to prevent the vehicle from moving. For
manual transmission models, move the shift
lever to N (Neutral). For automatic transmis-
sion models, move the selector lever to P
(Park).
● Be sure the ignition switch is in the OFF or
LOCK position when performing any parts
replacement or repairs.
● Never connect or disconnect the battery or
any transistorized component while the ig-
nition switch is in the ON position.
● Never leave the engine or automatic trans-
mission related component harnesses dis-
connected while the ignition switch is in the
ON position. ●
If you must work with the engine running,
keep your hands, clothing, hair and tools
away from moving fans, belts and any other
moving parts.
● It is advisable to secure or remove any loose
clothing and remove any jewelry, such as
rings, watches, etc. before working on your
vehicle.
● Always wear eye protection whenever you
work on your vehicle.
● If you must run the engine in an enclosed
space such as a garage, be sure there is
proper ventilation for exhaust gases to
escape.
● Never get under the vehicle while it is sup-
ported only by a jack. If it is necessary to
work under the vehicle, support it with
safety stands.
● Keep smoking materials, flame and sparks
away from fuel tank and the battery. ●
Your vehicle is equipped with an automatic
engine cooling fan. It may come on at any
time without warning, even if the ignition
key is in the OFF position and the engine is
not running. To avoid injury, always discon-
nect the negative battery cable before work-
ing near the fan.
● The fuel filter or fuel lines should be serviced
by an INFINITI retailer because the fuel lines
are under high pressure even when the en-
gine is off.
CAUTION
●Do not work under the hood while the engine
is hot. Turn the engine off and wait until it
cools down.
● Avoid direct contact with used engine oil and
coolant. Improperly disposed engine oil,
coolant, and/or other vehicle fluids can dam-
age the environment. Always conform to lo-
cal regulations for disposal of vehicle fluid.
MAINTENANCE PRECAUTIONS
Maintenance and do-it-yourself8-5

WARNING
●Prolonged and repeated contact with used
engine oil may cause skin cancer.
● Try to avoid direct skin contact with used oil.
If skin contact is made, wash thoroughly
with soap or hand cleaner as soon as
possible.
● Keep used engine oil out of reach of children. When checking or replacement is required, we
recommend an INFINITI retailer for servicing.
CAUTION
●
Use only Genuine NISSAN Matic S ATF. Do
not mix with other fluids.
● Using automatic transmission fluid other
than Genuine NISSAN Matic S ATF will cause
deterioration in driveability and automatic
transmission durability, and may damage
the automatic transmission, which is not
covered by the INFINITI new vehicle limited
warranty.
Check the fluid level in the reservoir.
The fluid level should be checked using the HOT
range (
1: HOT MAX.,2: HOT MIN.) at fluid
temperatures of 122 to 176°F (50 to 80°C) or
using the COLD range (
3: COLD MAX.,4:
COLD MIN.) at fluid temperatures of 32 to 86°F
(0 to 30°C).
If the fluid is below the MIN line, add Genuine
NISSAN PSF or equivalent. Remove the cap and
fill through the opening.
CAUTION
● Do not overfill.
● Use Genuine NISSAN PSF or equivalent.

Technical and consumer information9-3

MEASUREMENT OF WEIGHTS
Secure loose items to prevent weight
shifts that could affect the balance of
your vehicle. When the vehicle is loaded,
drive to a scale and weigh the front and
the rear wheels separately to determine
axle loads. Individual axle loads should
not exceed either of the gross axle
weight ratings (GAWR). The total of the
axle loads should not exceed the gross
vehicle weight rating (GVWR). These rat-
ings are given on the vehicle certifica-
tion label. If weight ratings are ex-
ceeded, move or remove items to bring
all weights below the ratings.
Your vehicle was designed to be used to carry
passengers and cargo. INFINITI does not recom-
mend trailer towing, because it places addi-
tional loads on your vehicle’s engine, drivetrain,
steering, braking, and other systems.
An INFINITI Towing Guide (U.S. only) is available
on the website at
www.InfinitiUSA.com. This guide includes infor-
mation on trailer towing capability and the
special equipment required for proper towing.
CAUTION
Vehicle damage resulting from towing a trailer
is not covered by INFINITI warranties.
FLAT TOWING
Towing your vehicle with all four wheels on the
ground is sometimes called flat towing. This
method is sometimes used when towing a
vehicle behind a recreational vehicle, such as a
motor home.
CAUTION
●Failure to follow these guidelines can result
in severe transmission damage.
● Whenever flat towing your vehicle, always
tow forward, never backward. ●
DO NOT tow any automatic transmission ve-
hicle with all four wheels on the ground (flat
towing). Doing so WILL DAMAGE internal
transmission parts due to lack of transmis-
sion lubrication.
● For emergency towing procedures refer to
“TOWING RECOMMENDED BY INFINITI” in the
“6. In case of emergency” section of this
manual.
Automatic transmission
To tow a vehicle equipped with an automatic
transmission, an appropriate vehicle dolly
MUST be placed under the towed vehicle’s drive
wheels. Alwaysfollow the dolly manufacturer’s
recommendations when using their product.
Manual transmission
● Always tow with the manual transmission in
Neutral.
● Your vehicle speed should never exceed 70
MPH (112 km/h) when flat towing your ve-
hicle.
● After towing 500 miles, start and idle the
engine with the transmission in Neutral for
two minutes. Failure to idle the engine after
every 500 miles of towing may cause dam-
age to the transmission’s internal parts.
