wheel nut wrench, tighten the wheel
nuts securely in the sequence illustrated
(
A,B,C,D,E). Lower the vehicle
completely.
WARNING
∙ Incorrect wheel nuts or improperly tight- ened wheel nuts can cause the wheel to
become loose or come off. This could
cause an accident.
∙ Do not use oil or grease on the wheel studs or nuts. This could cause the nuts to
become loose.
∙ Retighten the wheel nuts when the ve- hicle has been driven for 1,000 km
(621 miles) (also in cases of a flat tire,
etc.).
As soon as possible, tighten the wheel nuts
to the specified torque with a torque wrench.
Wheel nut tightening torque: 113 N·m (83 ft-lb)
The wheel nuts must be kept tightened to
specification at all times. It is recommended
that wheel nuts be tightened to specifica-
tions at each lubrication interval. Adjust tire pressure to the COLD pressure.
COLD pressure: After the vehicle has been
parked for 3 hours or more or driven less
than 1.6 km (1 mile).
COLD tire pressures are shown on the Tire
Placard affixed to the driver side center pil-
lar.
5. Securely store the flat tire, tools and jacking equipment in the vehicle.
6. Close the liftgate.
WARNING
∙ Always make sure that the spare tire and jacking equipment are properly secured
after use. Such items can become danger-
ous projectiles in an accident or sudden
stop.
∙ The spare tire is designed for emergency use. For additional information, refer to
“Wheels and tires” in the “Maintenance
and do-it-yourself” section of this
manual. ∙ When re-installing the spare tire under
the vehicle after use, be sure to secure it
with the tire stem facing down toward
the ground. If the spare tire is improperly
secured with the tire stem facing up to-
wards the bottom of the vehicle, there is
an increased risk of separating from the
vehicle in the event of crash which may
pose a hazard in traffic or risk of injury to
others.

Front-Wheel Drive (FWD) models
with Continuously Variable
Transmission (CVT)
INFINITI recommends that your vehicle be
towed with the driving (front) wheels off the
ground or place the vehicle on a flatbed truck
as illustrated.
CAUTION
∙ Never tow CVT models with the frontwheels on the ground or four wheels on
the ground (forward or backward), as
this may cause serious and expensive
damage to the transmission. If it is neces-
sary to tow the vehicle with the rear
wheels raised always use towing dollies
under the front wheels.
∙ When towing CVT models with the rear wheels on the ground or on towing
dollies: – Place the ignition switch in the OFF
position, and secure the steering
wheel in a straight-ahead position
with a rope or similar device. Never
secure the steering wheel by placing
the ignition switch in the LOCK posi-
tion. This may damage the steering
lock mechanism (for models with a
steering lock mechanism).

Outside the vehicle
The maintenance items listed here should be
performed from time to time unless other-
wise specified.
Doors and hoodCheck that all doors and the
hood operate smoothly as well as the back
door, trunk lid and hatch. Also make sure that
all latches lock securely. Lubricate if neces-
sary. Make sure that the secondary latch
keeps the hood from opening when the pri-
mary latch is released.
When driving in areas using road salt or other
corrosive materials, check lubrication fre-
quently.
Lights* Clean the headlights on a regular ba-
sis. Make sure that the headlights, stop lights,
tail lights, turn signal lights and other lights
are all operating properly and installed se-
curely. Also check the aim of the headlights.
Tires* Check the pressure with a gauge often
and always prior to long distance trips. Adjust
the pressure in all tires, including the spare, to
the pressure specified. Check carefully for
damage, cuts or excessive wear.
Tire rotation* In the case that Two-Wheel
Drive (2WD) and front and rear tires are same
size; tires should be rotated every 10,000 km
(6,000 miles). Tires marked with directional indicators can only be rotated between front
and rear. Make sure that the directional indi-
cators point in the direction of wheel rotation
after the tire rotation is completed.
In the case that Four-Wheel Drive and All
Wheel Drive (4WD/AWD) and front and rear
tires are the same size; tires should be rotated
every 5,000 km (3,000 miles). Tires marked
with directional indicators can only be ro-
tated between front and rear. Make sure that
the directional indicators point in the direc-
tion of wheel rotation after the tire rotation is
completed.
In the case that front tires are different size
from rear tires; tires cannot be rotated.
The timing for tire rotation may vary accord-
ing to your driving habits and the road sur-
face conditions.
Tire Pressure Monitoring System (TPMS)
transmitter components (if so equipped)
Re-
place the TPMS transmitter grommet seal,
valve core and cap when the tires are re-
placed due to wear or age.
Wheel alignment and balance If the vehicle
should pull to either side while driving on a
straight and level road, or if you detect un-
even 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.
Windshield
Clean the windshield on a regular
basis. Check the windshield at least every six
months for cracks or other damage. Repair as
necessary.
Wiper blades* Check for cracks or wear if not
functioning correctly. Replace as necessary.
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.
Brake pedal* Check the pedal for smooth
operation and make sure that it is the proper
distance from the floor mat when depressed
fully. Check the brake booster function. Be
sure to keep the floor mat away from the
pedal.
Parking brake* Check the parking brake op-
eration regularly. Check that the lever (if so
equipped) or the pedal (if so equipped) has
the proper travel. Also make sure that the
Maintenance and do-it-yourself8-3

vehicle is held securely on a fairly steep hill
when only the parking brake is applied.
Seat beltsCheck that all parts of the seat belt
system (for example, buckles, anchors, ad-
justers and retractors) operate properly and
smoothly, and are installed securely. Check
the belt webbing for cuts, fraying, wear or
damage.
Steering wheel Check for changes in the
steering condition, such as excessive play,
hard steering or strange noises.
Warning lights and chimes Make sure that all
warning lights and chimes are operating
properly.
Windshield defogger Check that the air
comes out of the defogger outlets properly
and in good quantity when operating the
heater or air conditioner.
Windshield wiper and washer* Check that
the wipers and washer operate properly and
that the wipers do not streak.
Under the hood and vehicle
The maintenance items listed here should be
checked periodically (for example, each time
you check the engine oil or refuel). Battery* (except for maintenance free bat-
teries)
Check the fluid level in each cell. The
fluid should be at the bottom of the filler
opening. Vehicles operated in high tempera-
tures or under severe conditions require fre-
quent checks of the battery fluid level.
NOTE:
Care should be taken to avoid situations
that can lead to potential battery discharge
and potential no-start conditions such as:
1. Installation or extended use of elec-
tronic 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.
Brake (and clutch) fluid level(s)* For Manual
Transmission (M/T) model; make sure that
the brake and clutch fluid levels are between
the MAX and MIN lines on the reservoirs.
Except for Manual Transmission (M/T)
model; make sure that the brake fluid level is
between the MAX and MIN lines on the res-
ervoir. Engine coolant level*
Check the coolant level
when the engine is cold. Make sure that the
coolant level is between the MAX and MIN
lines on the reservoir.
Engine drive belt(s)* Make sure the drive
belt(s) is not frayed, worn, cracked or oily.
Engine oil level* Check the level after parking
the vehicle (on level ground) and turning off
the engine.
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 fuel fumes
are evident, check for the cause and have it
corrected immediately.
Power steering fluid level* and lines Check
the level when the fluid is cold with the engine
off. Check the lines for proper attachment,
leaks, cracks, etc.
Windshield-washer fluid* Check that there is
adequate fluid in the reservoir.
