NOTE
•The wheel lock bolt has an individual code.
A wheel lock key with other than the indi-
vidual code cannot remove the wheel lock
bolt. If you lose the wheel lock key, it is
recommended you contact an INFINITI re-
tailer for a duplicate with the original
wheel lock key code.
•Record the key number and keep it in a
safe place, not in the vehicle.
•When you ask for a service at an INFINITI
retailer, make sure to keep the lock key in
the vehicle. Otherwise, wheels cannot be
removed and the service cannot be per-
formed. For the jump-starting procedure, use only the
jump-starting connection point, consisting of
a positive terminal and an earth point, in the
engine compartment.
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 bat-
tery.
•Do not allow battery fluid to come into
contact with eyes, skin, clothes or
painted surfaces. Battery fluid is a cor-
rosive sulfuric acid which can cause se-
vere burns. If the fluid should come into
contact with anything, immediately
flush the contacted area with water.
•Keep the battery out of the reach of chil-
dren.
•The booster battery must be rated at 12
volts. Use of an improperly rated bat-
tery can damage your vehicle.
•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.
JUMP STARTING

button and use the key (see " Push-
button ignition switch (if equipped)" in
the "5. Starting and driving" section).
Otherwise the automatic transmission
may shift to position P (Park) when the
driver's or front passenger door are
opened, which could lead to damage to
the transmission.
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
•To avoid potential injury, 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 back- ward.
•Shift back and forth between R (Reverse)
and D (Drive).
•Apply the accelerator as little as possible
to maintain the rocking motion.
•Release the accelerator pedal before shift-
ing between R (Reverse) and D (Drive).
•Do not spin the tires above 35 MPH (55
km/h).
5. If the vehicle cannot be freed after a few tries, contact a professional towing ser-
vice to remove the vehicle.

listed in the fuse allocation chart.
If the newly inserted fuse also blows, have
the cause traced and rectified. It is recom-
mended you visit an INFINITI retailer for this
service.
The fuses in your vehicle disconnect faulty
circuits. if a fuse blows, all the components on
the circuit and their functions will fail.
BEFORE REPLACING A FUSE
•Secure the vehicle against rolling away.
•Switch off all electrical consumers.
•Remove the key from the ignition lock.
The fuses are located in various fuse boxes:
•Fuse box in the engine compartment on
the left-hand side of the vehicle, when
viewed in the direction of travel.
•Fuse box in the front-passenger footwell.
The fuse allocation chart is on the fuse box in
the front-passenger footwell.
