Distance: Less than 50 miles (80
km)
.Four wheels on the ground:
Speed: Below 70 MPH (112 km/h)
Distance: Less than 500 miles
(800 km)
—If the speed or distance mustnecessarily be greater, remove the
propeller shaft before towing to
prevent damage to the drivetrain.

.Never tow a vehicle using the vehicle tie
downs or recovery hooks.
. Always pull the cable straight out from
the front of the vehicle. Never pull on the
vehicle at an angle.
. Pulling devices should be routed so they
do not touch any part of the suspension,
steering, brake or cooling systems.
. Pulling devices such as ropes or canvas
straps are not recommended for use in
vehicle towing or recovery.

GUID-7E681473-8113-4EFB-B5DA-7A7484E2409FDuring the normal day-to-day operation of
the vehicle, general maintenance should
be performed regularly as prescribed in
this section. If you detect any unusual
sounds, vibrations or smell, be sure to
check for the cause or have an INFINITI
retailer do it promptly. In addition, you
should notify an INFINITI retailer if you
think that repairs are required.
When performing any checks or mainte-
nance work, see“Maintenance precau-
tions” (P.8-5).
EXPLANATION OF MAINTENANCE
ITEMS
GUID-4DADA991-350E-4791-AC1F-B7D348E957C5Additional information on the following
items with “*”is found later in this
section.
Outside the vehicleGUID-935F9711-28E8-44B7-926E-055C6CC77282The maintenance items listed here should
be performed from time to time, unless
otherwise specified.
Doors and engine hood: Check that all
doors and the engine hood operate prop-
erly. Also ensure that all latches lock
securely. Lubricate hinges, latches, latch
pins, rollers and links if necessary. Make
sure that the secondary latch keeps the
hood from opening when the primary latch is released.
When driving in areas using road salt or
other corrosive materials, check lubrication
frequently.
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 check-
ing the tires, make sure no wheel nuts are
missing, and check for any loose wheel
nuts. Tighten if necessary.
Tire rotation*: Tires cannot be rotated, as
front tires are a different size from rear
tires and the direction of wheel rotation is
fixed in each tire.
Tires*: Check the pressure with a gauge
often and always prior to long distance
trips. If necessary, adjust the pressure in
all tires, including the spare, to the
pressure specified. Check carefully for
damage, cuts or excessive wear.
Tire Pressure Monitoring System (TPMS)
transmitter components: Replace the TPMS
transmitter 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 Book-
let.
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 vehicleGUID-AAA8A546-692D-407E-9E98-33BD16F490A2The maintenance items listed here should
be checked on a regular basis, such as
when performing scheduled 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) mechan-
ism:On a fairly steep hill, check that the
vehicle is held securely with the selector
lever in the P (Park) position without
applying any brakes.
Brake pedal: Check the pedal for smooth
operation. 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
operation regularly. The vehicle should be
securely held on a fairly steep hill with only
the parking brake applied. If the parking
brake needs adjusted, see an INFINITI
retailer.
Seat belts: Check that all parts of the seat
belt system (for example, buckles, an-
chors, adjusters and retractors) operate
properly and smoothly, and are installed
securely. Check the belt webbing for cuts, fraying, wear or damage.
Seats:
Check seat position controls such as
seat adjusters, seatback recliners, etc. to
ensure they operate smoothly and that all
latches lock securely in every position.
Check that the head restraints move up
and down smoothly and that the locks (if
so equipped) hold securely in all latched
positions.
Steering wheel: Check for changes in the
steering conditions, such as excessive free
play, hard steering or strange noises.
Warning lights and chimes: Make sure that
all warning lights and chimes are operating
properly.
Windshield defroster: Check that the air
comes out of the defroster outlets properly
and in sufficient quantity when operating
the heater or air conditioner.
Windshield wiper and washer*: Check that
the wipers and washers operate properly
and that the wipers do not streak.
Under the hood and vehicleGUID-6687B186-528E-4C5C-A54D-1DCA274537D4The maintenance items listed here should
be checked periodically (for example, each
time you check the engine oil or refuel).
Battery*: Check the fluid level in each cell. It should be between the MAX and MIN
lines. Vehicles operated in high tempera-
tures or under severe condition require
frequent checks of the battery fluid level.
Brake and clutch fluid levels*:
Make sure
that the brake and clutch fluid levels are
between the MAX and MIN lines on the
reservoir.
Engine coolant level*: Check the coolant
level when the engine is cold.
Engine drive belt*: Make sure that the
drive belt is not frayed, worn, cracked or
oily.
Engine oil level*: Check the level after
parking the vehicle on a level surface and
turning off the engine. Wait more than 15
minutes for the oil to drain back into the oil
pan.
Exhaust system: Make sure there are no
loose supports, cracks or holes. If the
sound of the exhaust seems unusual or
there is a smell of exhaust fumes, im-
mediately have the exhaust system in-
spected by an INFINITI retailer. (See
“Precautions when starting and driving”
(P.5-3) for exhaust gas (Carbon monoxide).)
Fluid leaks: Check under the vehicle for
fuel, oil, water or other fluid leaks after the

vehicle has been parked for a while. Water
dripping from the air conditioner after use
is normal. If you should notice any leaks or
if gasoline fumes are evident, check for the
cause and have it corrected immediately.
Power steering fluid level* and lines:
Check the level with the engine off. Check
the lines for proper attachment, leaks,
cracks, etc.
Radiator and hoses:Check the front of the
radiator and clean off any dirt, insects,
leaves, etc., that may have accumulated.
Make sure the hoses have no cracks,
deformation, rot or loose connections.
Underbody: The underbody is frequently
exposed to corrosive substances such as
those used on icy roads or to control dust.
It is very important to remove these
substances, otherwise rust will form on
the floor pan, frame, fuel lines and around
the exhaust system. At the end of winter,
the underbody should be thoroughly
flushed with plain water, being careful to
clean those areas where mud and dirt may
accumulate. For additional information,
see “Cleaning exterior” (P.7-2).
Windshield washer fluid*: Check that there
is adequate fluid in the reservoir.
GUID-10AF39EE-6E4C-416A-9D4D-B725EAC05CA0When performing any inspection or main-
tenance work on your vehicle, always take
