2018 INFINITI QX30 key battery

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.
