2014 INFINITI Q70 HYBRID key battery

The hill start assist system automatically
keeps the brakes applied to help prevent
the vehicle from rolling backwards in the
time it takes the driver to release the brake
pedal and apply the accelerator when the
vehicle is stopped on a hill.
The hill start assist system will operate
automatically under the following condi-
tions:
.The transmission is shifted to a forward
or reverse gear.
. The vehicle is stopped completely on a
hill by applying the brake.
The maximum holding time is 2 seconds.
After 2 seconds the vehicle will begin to
roll back and the hill start assist system
will stop operating completely.
The hill start assist system will not operate
when the transmission is shifted to the N
(Neutral) or P (Park) position or on a flat
and level road.
When staring the vehicle on a steep uphill
grade, wait one second after shifting the
shift lever into the driving position.FREEING A FROZEN DOOR LOCK
To prevent a door lock from freezing, apply
deicer through the key hole. If the lock
becomes frozen, heat the key before
inserting it into the key hole or use the
Intelligent Key system.
ANTIFREEZE
In the winter when it is anticipated that the
outside temperature will drop below 328F
(08C), check antifreeze to assure proper
winter protection. For additional informa-
tion, see “Engine cooling system” (P.8-9).
12-VOLT BATTERY
If the 12-volt battery is not fully charged
during extremely cold weather conditions,
the 12-volt battery fluid may freeze and
damage the 12-volt battery. To maintain
maximum efficiency, the 12-volt battery
should be checked regularly. For additional
information, see“12-volt battery” (P.8-18).
DRAINING OF COOLANT WATER
If the vehicle is to be left outside without
antifreeze, drain the cooling system, in-
cluding the engine block. Refill before
operating the vehicle. For details, see
“Engine cooling system” (P.8-9) and“In-
verter cooling system” (P.8-11).
TIRE EQUIPMENT
SUMMER tires have a tread designed to
provide superior performance on dry pave-
ment. However, the performance of these
tires will be substantially reduced in snowy
and icy conditions. If you operate your
vehicle on snowy or icy roads, INFINITI
recommends the use of MUD & SNOW or
ALL SEASON tires on all four wheels.
Consult an INFINITI retailer for the tire
type, size, speed rating and availability
information.
For additional traction on icy roads,
studded tires may be used. However, some
U.S. states and Canadian provinces prohi-
bit their use. Check local, state and
provincial laws before installing studded
tires.
Skid and traction capabilities of studded
snow tires, on wet or dry surfaces, may be
poorer than that of non-studded snow
tires.
Tire chains may be used. For details, see
“Tire chains”(P.8-39).

8-6Maintenance and do-it-yourself
.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 key 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.
CAUTION
.Do not work under the hood while the
engine is hot. Turn the hybrid system off
and wait until it cools down. .
Avoid direct contact with used engine oil
and coolant. Improperly disposed engine
oil, coolant, and/or other vehicle fluids
can damage the environment. Always
conform to local regulations for disposal
of vehicle fluid.
. Never leave the engine or the transmis-
sion related component harness connec-
tor 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.
This “8. Maintenance and do-it-yourself”
section gives instructions regarding only
those items which are relatively easy for an
owner to perform.
A genuine INFINITI Service Manual is also
available. (See “Owner’s Manual/Service
Manual order information” (P.9-21).)
You should be aware that incomplete or
improper servicing may result in operating
difficulties or excessive emissions, and
could affect your warranty coverage. If in
doubt about any servicing, we recommend
that it be done by an INFINITI retailer.

Extended storage fuse switch (if so
equipped)
To reduce battery drain, the extended
storage fuse switch comes from the factory
switched off. Prior to delivery of your
vehicle, the switch is pushed in (switched
on) and should always remain on. If any
electrical equipment does not operate,
remove the extended storage switch and
check for an open fuse.
If any electrical equipment does not
operate, remove the extended storage fuse
switch and check for an open fuse.NOTE:
If the extended storage fuse switch mal-
functions, or if the fuse is open, it is not
necessary to replace the switch. In this
case, remove the extended storage fuse
switch and replace it with a new fuse of
the same rating.
How to remove the extended storage fuse
switch:
1. To remove the extended storage switch,
be sure the ignition switch is in the OFF
or LOCK position.
2. Be sure the headlight switch is in the OFF position.
3. Remove the fuse box cover.
4. Pinch the locking tabs*1found on
each side of the storage fuse switch.
5. Pull the storage fuse switch straight out from the fuse box
*2.
CAUTION
Be careful not to allow children to swallow
the battery and removed parts.
INTELLIGENT KEY BATTERY REPLACEMENT

SDI2451
To replace the battery:
1. Release the lock knob at the back of theIntelligent Key and remove the mechan-
ical key.
2. Insert a flat-blade screwdriver wrapped with a cloth into the slit of the corner
and twist it to separate the upper part from the lower part.
3. Replace the battery with a new one.
Recommended battery:
CR2025 or equivalent
.Do not touch the internal circuit andelectric terminals as it could cause a
malfunction.
.Hold the battery by the edges.
Holding the battery across the con-
tact points will seriously deplete the
storage capacity.
.Make sure that the + side faces thebottom of the case.SDI2452
4. Align the tips of the upper and lower
parts, and then push them together
until it is securely closed.
5. Operate the buttons to check its operation.
See an INFINITI retailer if you need any
assistance for replacement.
