4. Lower the vehicle slowly until the tiretouches the ground. Then, with the wheel
nut wrench, tighten the wheel nuts se-
curely in the sequence illustrated (
OA,OB,
OC,OD,OE). 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 621 miles
(1,000 km) (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: 83 ft-lb (113 N·m) 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 vehicle has been
parked for 3 hours or more or driven less
than 1 mile (1.6 km).
COLD tire pressures are shown on the Tire
and Loading Information label affixed to the
driver side center pillar.
5. Securely store the flat tire, tools and jack-
ing 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 dan-
gerous projectiles in an accident or sud-
den stop.
• The spare tire is designed for emergency
use. For additional information, see
“Wheels and tires” (P. 8-28). To 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 dam-
age your vehicle.
• Explosive hydrogen gas is always pres-
ent in the vicinity of the battery. Keep all
sparks and flames away from the
battery.
• Do not allow battery fluid to come into
contact with eyes, skin, clothing or
painted surfaces. Battery fluid is a corro-
sive sulfuric acid solution which can
cause severe burns. If the fluid should
come into contact with anything, imme-
diately flush the contacted area with
water.
• Keep battery out of the reach of children.
• The booster battery must be rated at 12
volts. Use of an improperly rated battery
can damage your vehicle.
JUMP STARTING
6-12In case of emergency

•Whenever working on or near a battery,
always wear suitable eye protectors (for
example, goggles or industrial safety
spectacles) and remove rings, metal
bands, or any other jewelry. Do not lean
over the battery when jump starting.
• Do not attempt to jump start a frozen
battery. It could explode and cause seri-
ous injury.
• Your vehicle has an automatic engine
cooling fan. It could come on at any time.
Keep hands and other objects away from
it.
WARNING
Always follow the instructions below. Fail-
ure to do so could result in damage to the
charging system and cause personal injury.
1. If the booster battery is in another vehicle, position the two vehicles to bring their
batteries near each other.
Do not allow the two vehicles to touch.

Two-Wheel Drive models with
automatic transmission
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 automatic transmission mod-
els with the front wheels 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 necessary to tow the vehicle with the
rear wheels raised always use towing
dollies under the front wheels.

•When towing automatic transmission
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).
NOTE:
If the battery is completely drained the
transmission will not manually shift to other
positions.
VEHICLE RECOVERY (freeing a
stuck vehicle)
WARNING
To avoid vehicle damage, serious personal
injury or death when recovering a stuck
vehicle:
• Contact a professional towing service to
recover the vehicle if you have any ques-
tions regarding the recovery procedure. •
Tow chains or cables must be attached
only to main structural members of the
vehicle.
• Do not use the vehicle tie-downs to tow
or free a stuck vehicle.
• Only use devices specifically designed for
vehicle recovery and follow the manu-
facturer's instructions.
• Always pull the recovery device straight
out from the front of the vehicle. Never
pull at an angle.
• Route recovery devices so they do not
touch any part of the vehicle except the
attachment point.
If your vehicle is stuck in sand, snow, mud,
etc., use a tow strap or other device designed
specifically for vehicle recovery. Always fol-
low the manufacturer's instructions for the
recovery device.Rocking a stuck vehicle
WARNING
• Stand clear of a stuck vehicle.
• Do not spin your tires at high speed. This
could cause them to explode and result in
serious injury. Parts of your vehicle could
also overheat and be damaged. If your vehicle is stuck in sand, snow, mud,
etc., use the following procedure:
1. Turn off the Vehicle Dynamic Control
(VDC) system.
2. Make sure the area in front and behind the vehicle is clear of obstructions.
3. Turn the steering wheel right and left to clear an area around the front tires.
4. Slowly rock the vehicle forward and backward.
• Shift back and forth between R (Re- verse) and D (Drive).
• Apply the accelerator as little as pos- sible to maintain the rocking motion.
• Release the accelerator pedal before shifting between R (Reverse) and D
(Drive).
• Do not spin the tires above 35 mph (55 km/h).

When performing any inspection or maintenance
work on your vehicle, always take care to pre-
vent serious accidental injury to yourself or dam-
age 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 mov-
ing. Push the park button to engage the
P (Park) position.
• Be sure the ignition switch is in the OFF
or LOCK position when performing any
parts replacement or repairs.
• If you must work with the engine run-
ning, 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 work-
ing on your vehicle.
• Always wear eye protection whenever
you work on your vehicle.
• Your vehicle is equipped with an auto-
matic engine cooling fan. It may come on
at any time without warning, even if the
ignition switch is in the OFF position and the engine is not running. To avoid injury,
always disconnect the negative battery
cable before working near the fan.
• 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
supported 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 the fuel tank and battery.
• Because the fuel lines on gasoline engine
models are under high pressure even
when the engine is off, it is recommended
that you visit an INFINITI retailer for ser-
vice of the fuel filter or fuel lines.
CAUTION
• Do not work under the hood while the
engine is hot. Turn the engine off and
wait until it cools down.
• Avoid contact with used engine oil and
coolant. Improperly disposed engine oil,
engine coolant and/or other vehicle flu-
ids can damage the environment. Always
conform to local regulations for disposal
of vehicle fluid. •
Never leave the engine or automatic
transmission related component har-
nesses disconnected while the ignition
switch is in the ON position.
• Never connect or disconnect the battery
or any transistorized component while
the ignition switch is in the ON position.
NOTE:
If the battery is completely drained the
transmission will not manually shift to other
positions.
This “Do-it-yourself” section gives instruc-
tions regarding only those items which are
relatively easy for an owner to perform.
A Genuine INFINITI service manual is also
available. For additional information, see
“Owner’s Manual/Service Manual order in-
formation” (P. 10-36).
You should be aware that incomplete or im-
proper servicing may result in operating diffi-
culties or excessive emissions, and could af-
fect warranty coverage. If in doubt about any
servicing, it is recommended that you have it
done by an INFINITI retailer.
