ECU NISSAN LEAF 2017 1.G Repair Manual

CHECKING COOLANT LEVEL
Check the coolant levelin the reservoir when
the high-voltage parts are cold. If the coolant
level is below the MIN level
B, open the reservoir
cap and add coolant up to the MAX level
A.If
the reservoir is empty, check the coolant level in
the coolant reservoir when the high-voltage
parts are cold. If there is insufficient coolant in
the coolant reservoir, fill the coolant reservoir with
coolant up to the reservoir cap opening and also
add it to the reservoir up to the MAX level
A.
Tighten the cap securely after adding coolant. For additional information on the location of the
coolant reservoir, refer to “Motor compartment
check locations” in this section.
If the cooling system frequently requires
coolant, it is recommended that you visit a
NISSAN certified LEAF dealer.
CHANGING COOLANT
It is recommended that major cooling system
repairs should be performed by a NISSAN certi-
fied LEAF dealer. The service procedures can be
found in the appropriate NISSAN Service
Manual.
Improper servicing can result in reduced
heater performance.
WARNING
• To avoid the danger of being scalded, never change the coolant when the
motor compartment is hot.
• Never remove the coolant reservoir cap when the motor compartment is
hot. Serious burns could be caused by
high-pressure fluid escaping from the
radiator. • Avoid direct skin contact with used
coolant. If skin contact is made, wash
thoroughly with soap or hand cleaner
as soon as possible.
• Keep coolant out of reach of children and pets.
Coolant must be disposed of properly. Check
your local regulations.
Maintenance and do-it yourself8-9

• 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 elec-
tronic accessories that consume battery
power when the motor 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. 1. Remove the vent caps with a screwdriver as
shown. Use a cloth to protect the battery
case.

Checking tire pressure
1. Remove the valve stem cap from thetire.
2. Press the pressure gauge securely onto the valve stem. Do not press too
hard or force the valve stem sideways,
otherwise air will escape. If the hissing
sound of air escaping from the tire is
heard while checking the pressure, re-
position the gauge to eliminate this
leakage. 3. Remove the gauge.
4. Read the tire pressure on the gauge
stem and compare it to the specifica-
tion 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 release pressure. Re-
check 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 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 the
factory 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.
CHANGING WHEELS AND TIRES
Tire rotation
NISSAN recommends rotating the tires
every 5,000 miles (8,000 km) .
As soon as possible, tighten the
wheel nuts to the specified torque
using a torque wrench.
Wheel nut tightening torque:83 ft-lb (112 N·m)

Weight Rating (GAWR) for your vehicle.
For additional information, refer to “Mea-
surement of weights” in this section.
Also check tires for proper inflation pres-
sures. For additional information, refer to
the “Tire and Loading Information label” in
this section.
LOADING TIPS
• The GVW must not exceed the GVWRor 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 seat-
backs. In a sudden stop or colli-
sion, 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 oc-
cur, or it can change the way your
vehicle handles. This could result
in loss of control and cause per-
sonal injury.
•Overloading not only can
shorten the life of your vehicle
and the tire, but can cause un-
safe vehicle handling and longer
braking distances. This may
cause a premature tire failure,
which could result in a serious
accident and personal injury.
Failures caused by overloading
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 separately to determine axle
loads. Individual axle loads should not ex-
ceed either of the Gross Axle Weight
Ratings (GAWR) . The total of the axle
loads should not exceed the Gross Ve-
hicle Weight Rating (GVWR) . These rat-
ings are given on the vehicle certification
label. If weight ratings are exceeded,
move or remove items to bring all weights
below the ratings.
