ECU NISSAN LEAF 2014 1.G Repair Manual

• Keep the 12-volt battery surface clean and dry.
Clean the 12-volt battery with a solution of
baking soda and water.
• Make certain the terminal connections are clean
and securely tightened.
NOTE:
Care should be taken to avoid situations
that can lead to potential battery discharge
and potential no-start conditions such as:
1. Installation or extended use of electronic ac-
cessories that consume 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 battery may need to be
charged to maintain battery health.
WARNING
• Do not expose the 12-volt battery to
flames or electrical sparks. Hydrogen
gas generated by the 12-volt battery is
explosive. Do not allow 12-volt battery
fluid to contact your skin, eyes, fabrics
or painted surfaces. After touching a
12-volt battery or 12-volt battery cap,
do not touch or rub your eyes. Thor-
oughly wash your hands. If the acid
contacts your eyes, skin or clothing,
immediately flush with water for at
least 15 minutes and seek medical at-
tention.
• Do not operate the vehicle if the fluid
in the 12-volt battery is low. Low 12-
volt battery fluid can cause a higher
load on the 12-volt battery which can
generate heat, reduce battery life, and
in some cases lead to an explosion.
• When working on or near a 12-volt
battery, always wear suitable eye pro-
tection and remove all jewelry.
• 12-volt battery posts, terminals and re-
lated accessories contain lead and
lead compounds. Wash hands after
handling.
• Keep the 12-volt battery out of the
reach of children.Check the fluid level in each cell. It should be
between the UPPER LEVEL
1and LOWER
LEVEL
2lines.
If it is necessary to add fluid, add only distilled
water to bring the level to the indicator in each
filler opening.Do not overfill.

8-20Maintenance and do-it yourself

Checking tire pressure
1. Remove the valve stem cap from the tire.
2. Press the pressure gauge securely onto the
valve stem. Do not press too hard or force the
valve stem sideways, otherwise air will es-
cape. If the hissing sound of air escaping from
the tire is heard while checking the pressure,
reposition the gauge to eliminate this leakage.
3. Remove the gauge.
4. Read the tire pressure on the gauge stem and
compare it to the specification shown on the
Tire and Loading Information label.5. Add air to the tire as necessary. If too much air
is added, press the core of the valve stem
briefly with the tip of the gauge stem to re-
lease pressure. Recheck the pressure and
add or release air as necessary.
6. Install the valve stem cap.
7. Check the pressure of all of the tires.

TIRE LABELING
Federal law requires tire manufacturers to place
standardized information on the sidewall of all
tires. This information identifies and describes
the fundamental characteristics of the tire and
also provides the tire identification number (TIN)
for safety standard certification. The TIN can be
used to identify the tire in case of a recall.
Example
8-28Maintenance and do-it yourself

tires are identified by ALL SEASON and/or M&S
(Mud and Snow) on the tire sidewall. Snow tires
have better snow traction than All Season tires
and may be more appropriate in some areas.
Summer tires
NISSAN specifies summer tires on some models
to provide superior performance on dry roads.
Summer tire performance is substantially re-
duced in snow and ice. Summer tires do not have
the tire traction rating M&S on the tire sidewall.
If you plan to operate your vehicle in snowy or icy
conditions, NISSAN recommends the use of
SNOW tires or ALL SEASON tires on all four
wheels.
Snow tires
If snow tires are needed, it is necessary to select
tires equivalent in size and load rating to the
original equipment tires. If you do not, it can
adversely affect the safety and handling of your
vehicle.
Generally, snow tires will have lower speed rat-
ings than factory equipped tires and may not
match the potential maximum vehicle speed.
Never exceed the maximum speed rating of the
tire.If you install snow tires, they must be the same
size, brand, construction and tread pattern on all
four wheels.
For additional traction on icy roads, studded tires
may be used. However, some U.S. states and
Canadian provinces prohibit 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
Use of tire chains may be prohibited according to
location. Check the local laws before installing
tire chains. When installing tire chains, make sure
they are the proper size for the tires on your
vehicle and are installed according to the chain
manufacturer’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 stan-
dard minimum clearances between the tire and
the closest vehicle suspension or body compo-
nent required to accommodate the use of a win-
ter traction device (tire chains or cables) . The
minimum clearances are determined using thefactory equipped tire size. Other types may dam-
age your vehicle.
Use chain tensioners when recommended 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 affected.
Tire chains must be installed only on the
front wheels and not on the rear wheels.
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.

SECURING THE LOAD
There are tie down hooks located in the cargo
area as shown. The tie down hooks can be used
to secure cargo with ropes or other types of
straps.
Do not apply a total load of more than 4 lb
(2 kg) to a single hook when securing
cargo.
WARNING
• Properly secure all cargo with ropes or
straps 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.
• The child restraint top tether strap may
be damaged by contact with items in
the cargo area. Secure any items in the
cargo area. Your child could be seri-
ously injured or killed in a collision if
the top tether strap is damaged.
• 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.
LOADING TIPS
• The GVW must not exceed the 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 with ropes or
straps 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 not only can shorten the
life of your vehicle and the tire, but can
cause unsafe vehicle handling and lon-
ger braking distances. This may cause
a premature tire failure, which could
result in a serious accident and per-
sonal injury. Failures caused by over-
loading are not covered by the vehi-
cle’s warranty.
9-12Technical and consumer information

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 separately to deter-
mine axle loads. Individual 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 remove items to bring all weights below
the ratings.Do not tow a trailer with your vehicle.Towing your vehicle with all four wheels on the
ground is sometimes called flat towing. This
method is typically used when towing a vehicle
behind a recreational vehicle, such as a motor
home.
CAUTION
• Failure to follow these guidelines can
result in severe reduction gear dam-
age.
• DO NOT tow this vehicle with all four
wheels on the ground (flat towing) .
• For emergency towing procedures re-
fer to “Towing your vehicle” in the “In
case of emergency” section of this
manual.
