6. Push the ignition switch to the“ACC”
position. Then turn the compressor
switch to the ON (−) position and inflate
the tire up to the pressure that is
specified on the tire and loading
information label affixed to the driver’s
side center pillar if possible, or to the
minimum of 26 psi (180 kPa). Turn the
air compressor off briefly in order to
check the tire pressure with the pres-
sure gauge.
If the tire is inflated to higher than the
specified pressure, lower the tire pres-
sure by releasing air with the pressure
release valve. NOTE:
The compressor tire pressure gauge
may show a pressure reading of 87 psi
(600 kPa) for about 30 seconds while
inflating the tire. The pressure gauge is
indicating the pressure inside the
sealant can. When the sealant has
been injected into the tire the pressure
gauge will drop and indicate actual tire
pressure.
WARNING
.
To avoid serious personal injury while
using the emergency tire puncture repair
kit:
—Securely tighten the compressor
hose to the tire valve. Failure to do
so can cause the sealant to spray
into the air and get into your eyes or
on the skin.
. Do not stand directly beside the da-
maged tire while it is being inflated
because of the risk of the rupture. If
there are any cracks or bumps, turn the
compressor off immediately.
If the tire pressure does not increase to 26 psi (180 kPa) within 10 minutes, the
tire may be seriously damaged and
the
tire cannot be repaired with this tire
repair kit. Contact an INFINITI retailer.
7. When the tire pressure is at the
specified amount, turn the air compres-
sor off. If the pressure cannot be
inflated to the specified amount, the
air compressor can be turned off at the
minimum of 26 psi (180 kPa). Remove
the power plug from the power outlet
and quickly remove the hose from the
tire valve. Attach the protective cap and
valve cap. Properly stow the emergency
tire puncture repair kit in the trunk.
CAUTION
To avoid serious personal injury when
stowing the emergency tire puncture repair
kit:
. Keep the sealant bottle screwed into the
compressor. Failure to do so can cause
the sealant to spray into the air and get
into your eyes or on the skin.
8. Immediately drive the vehicle for 10
minutes or 2 miles (3 km) at a speed of

50 MPH (80 km/h) or less.
9. After driving, make sure that the air compressor switch is in the OFF posi-
tion, then screw the hose securely onto
the tire valve. Check the tire pressure
with the pressure gauge. The temporary
repair is completed if the tire pressure
does not drop.
Make sure the pressure is adjusted to
the pressure that is specified on the
tire and loading information label
before driving.
10. If the tire pressure drops, repeat the steps from 5 to 9. If the pressure drops
again or under 19 psi (130 kPa), the
tire cannot be repaired with this tire
repair kit. Contact an INFINITI retailer.
The sealant bottle and hose can not be
reused to repair another punctured tire.
Contact an INFINITI retailer to purchase
replacements.
After repairing tireGUID-4E33536E-075D-4123-B5DC-9F069D78BCDESee an INFINITI retailer for tire repair/
replacement as soon as possible.
WARNING
. After using Emergency Tire Sealant to
repair a minor tire puncture, do not drive
the vehicle at speeds faster than 50 MPH
(80 km/h).
. Immediately after using Emergency Tire
Sealant to repair a minor tire puncture,
take your vehicle to an INFINITI retailer
to inspect, and repair or replace the tire.
The Emergency Tire Sealant cannot
permanently seal a punctured tire. Con-
tinuing operation of the vehicle without
a permanent tire repair can lead to a
crash.
. If you used Emergency Tire Sealant to
repair a minor tire puncture, your
INFINITI retailer will also need to replace
the TPMS sensor in addition to repairing
or replacing the tire.
. INFINITI recommends using only INFINITI
Genuine Emergency Tire Sealant pro-
vided with your vehicle. Other tire
sealants may damage the valve stem
seal which can cause the tire to lose air
pressure.
GUID-5728BD27-D621-422D-90D6-784E66031447To start your engine with a booster battery,
the instructions and precautions below
must be followed.
WARNING
.If done incorrectly, jump starting can
lead to a battery explosion, resulting in
severe injury or death. It could also
damage your vehicle.
. Explosive hydrogen gas is always pre-
sent in the vicinity of the battery. Keep
all sparks and flames away from the
battery.
. Do not allow battery fluid to come into

INFINITI
GUID-ED9538D8-F70E-46EA-B7DC-D0B36C79F2F0INFINITI recommends that your vehicle be
towed with the driving (rear) wheels off the
ground or place the vehicle on a flat bed
truck as illustrated.
CAUTION
.Never tow automatic transmission mod-
els with the rear wheels on the ground
or four wheels on the ground (forward or
backward), as this may cause serious
and expensive damage to the drivetrain. If it is necessary to tow the vehicle with
the front wheels raised, always use
towing dollies under the rear wheels.
. When towing rear wheel drive models
with the front wheels on the ground or
on towing dollies: Push the ignition
switch to the ACC or ON position, and
secure the steering wheel in a straight-
ahead position with a rope or similar

ground (if you do not use towing dollies)
or four wheels on the ground:
—Push the ignition switch to the ON
position and turn off all accessories.
—Always release the parking brake.
—Move the transmission shift lever tothe N (Neutral) position.
—Observe the following restricted
towing speeds and distances for
manual transmission models only:
.Rear wheels on the ground:
Speed: Below 50 MPH (80 km/h)
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.

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

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
care to prevent serious accidental injury to
yourself or damage to the vehicle. The
following are general precautions which
should be closely observed.
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 mod-
els, move the shift lever to N (Neutral).
For automatic transmission models,
move the selector lever to P (Park).
