2014 INFINITI Q70-HYBRID ECU

8-18Maintenance and do-it-yourself
JVM0039X
The 12-volt battery*Ais located on the
left hand side of the trunk behind an
access panel.
. Keep the battery surface clean and dry.
Clean the battery with a solution of
baking soda and water.
. Make certain the terminal connections
are clean and securely tightened.
. If the vehicle is not to be used for 30
days or longer, disconnect the negative
(-) battery terminal cable to prevent
discharge.
NOTE:
Care should be taken to avoid situations that can lead to potential 12-volt battery
discharge and potential no-start condi-
tions such as:
1.
Installation or extended use of electro-
nic accessories that consume 12-volt
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 12-volt battery may
need to be charged to maintain 12-volt
battery health.WARNING
. Do not expose the battery to flames or
electrical sparks. Hydrogen gas gener-
ated by the battery is explosive. Do not
allow battery fluid to contact your skin,
eyes, fabrics or painted surfaces. After
touching a battery, do not touch or rub
your eyes. Thoroughly wash your hands.
If the acid contacts your eyes, skin or
clothing, immediately flush with water
for at least 15 minutes and seek medical
attention. .
The Hybrid vehicle uses a special bat-
tery. If the battery needs to be replaced,
use a battery of the same design. Using
the wrong battery can cause hydrogen
gas to build up in the vehicle, which
could lead to an explosion and personal
injury.
. When working on or near a battery,
always wear suitable eye protection and
remove all jewelry.
. Battery posts, terminals and related
accessories contain lead and lead com-
pounds. Wash hands after handling.
. Keep battery out of the reach of children.

If it is necessary to replace, contact an
INFINITI retailer.
JUMP STARTING
If jump starting is necessary, see “Jump
starting” (P.6-10). If the hybrid system
does not start by jump starting, the 12-
volt battery may have to be replaced.
Contact an INFINITI retailer.WARNING
Be sure the engine and the ignition switch
are off and that the parking brake is
engaged securely.
CAUTION
Be sure to use the correct socket to remove
the spark plugs. An incorrect socket can
damage the spark plugs.

SPARK PLUGS

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.

TIRE CHAINS
Use of tire chains may be prohibited
according to location. Check the local laws
before installing tire chains. When instal-
ling tire chains, make sure they are the
proper size for the tires on your vehicle and
are installed according to the chain man-
ufacturer’s suggestions. Use only SAE
Class S chains. Class“S”chains are used
on vehicles with restricted tire to vehicle
clearance. Vehicles that can use Class “S”
chains are designed to meet the SAE
standard minimum clearances between
the tire and the closest vehicle suspension
or body component required to accommo-
date the use of a winter traction device (tire
chains or cables). The minimum clearances
are determined using the factory equipped
tire size. Other types may damage your
vehicle. Use chain tensioners when recom-
mended by the tire chain manufacturer to
ensure a tight fit. Loose end links of the
tire chain must be secured or removed to
prevent the possibility of whipping action
damage to the fenders or underbody. If
possible, avoid fully loading your vehicle
when using tire chains. In addition, drive at
a reduced speed. Otherwise, your vehicle
may be damaged and/or vehicle handling and performance may be adversely af-
fected.
Tire chains must be installed only on the
rear wheels and not on the front wheels.
Never install tire chains on a TEMPORARY
USE ONLY spare tire.
Do not use tire chains on dry roads. Driving
with tire chains in such conditions can
cause damage to the various mechanisms
of the vehicle due to some overstress.
SDI1662
CHANGING WHEELS AND TIRES
Tire rotation
INFINITI recommends rotating the
tires every 5,000 miles (8,000 km).
(See
“Flat tire” (P.6-3) for tire repla-
cing procedures.)
As soon as possible, tighten the
wheel nuts to the specified torque
with a torque wrench.
Wheel nut tightening torque:80 ft-lb (108 N·m)

9-16Technical and consumer information
cargo and luggage load capacity
of your vehicle.
Before driving a loaded vehicle,
confirm that you do not exceed the
Gross Vehicle Weight Rating (GVWR)
or the Gross Axle Weight Rating
(GAWR) for your vehicle. (See “Mea-
surement of weights” (P.9-16).)
Also check tires for proper inflation
pressures. See the Tire and Loading
Information label.
LOADING TIPS
.The GVW must not exceed GVWR or GAWR as specified on the F.M.V.
S.S./C.M.V.S.S. certification label.
.Do not load the front and rear axle
to the GAWR. Doing so will exceed
the GVWR.
WARNING
.Properly secure all cargo to help
prevent it from sliding or shifting.
Do not place cargo higher than the seatbacks. In a sudden stop or
collision, unsecured cargo could
cause personal injury.
.Do not load your vehicle any
heavier than the GVWR or the
maximum front and rear GAWRs.
If you do, parts of your vehicle can
break, tire damage could occur, or
it can change the way your vehicle
handles. This could result in loss
of control and cause personal
injury.
.Overloading could not only short-
en the life of your vehicle and the
tires, but also could lead to
hazardous vehicle handling and
long braking distance. This may
cause a premature tire malfunc-
tion, which could result in a
serious accident and personal in-
jury. Failures caused by overload-
ing are not covered by the
vehicle’s warranty.
MEASUREMENT OF WEIGHTS
Secure loose items to prevent weight
shifts that could affect the balance of
your vehicle. When the vehicle is
loaded, drive to a scale and weigh
the front and the rear wheels sepa-
rately to determine axle loads. In-
dividual axle loads should not
exceed either of the gross axle
weight ratings (GAWR). The total of
the axle loads should not exceed the
gross vehicle weight rating (GVWR).
These ratings are given on the
vehicle certification label. If weight
ratings are exceeded, move or re-
move items to bring all weights
below the ratings.

361-4792.Do not attempt to test the vehicle on a
dynamometer (such as the dynamometers
used by some states for emissions test-
ing), or similar equipment. Doing so may
cause damage to the drivetrain or the high
voltage battery. Make sure you inform test
facility personnel that your vehicle is
hybrid. Using the wrong test equipment
may result in drivetrain damage or un-
expected vehicle movement which could
result in serious vehicle damage or pear-
sonal injury.
Due to legal requirements in some states/
areas, your vehicle may be required to be
in what is called the“ready condition”for
an Inspection/Maintenance (I/M) test of
the emission control system.
The vehicle is set to the “ready condition”
when it is driven through certain driving
patterns. Usually, the “ready condition”
can be obtained by ordinary usage of the
vehicle.
If a powertrain system component is
repaired or the 12-volt battery is discon-
nected, the vehicle may be reset to a “not
ready condition”. Before taking the I/M
test, check the vehicle’s inspection/main-
tenance test readiness condition. Place the
ignition switch in the ON position without starting the engine. If the Malfunction
Indicator Light (MIL) comes on steady for
20 seconds and then blinks for 10
seconds, the I/M test condition is
“not
ready”. If the MIL does not blink after 20
seconds, the I/M test condition is “ready”.
Contact an INFINITI retailer to set the
“ready condition” or to prepare the vehicle
for testing.
