The VDC system uses various sensors to monitor
driver inputs and vehicle motion. Under certain
driving conditions, the VDC system helps to per-
form the following functions.
• Controls brake pressure to reduce wheel slip onone slipping drive wheel so power is transferred
to a drive wheel on the same axle that is not
slipping.
• Controls brake pressure and traction motor out- put to reduce drive wheel slip based on vehicle
speed (traction control function) .
• Controls brake pressure at individual wheels and traction motor output to help the driver
maintain control of the vehicle in the following
conditions. – understeer (vehicle tends to not follow the steered path despite increased steering in-
put) .
– oversteer (vehicle tends to spin due to cer- tain road or driving conditions) .
The VDC system can help the driver maintain
control of the vehicle, but it cannot prevent loss of
vehicle control in all driving situations.
When the VDC system operates, the
warning in the instrument panel flashes. When
the warning flashes, note the following items. • The road may be slippery or the system may
determine some action is required to help keep
the vehicle on the steered path.
• You may feel a pulsation in the brake pedal and hear a noise or vibration from under the hood.
This is normal and indicates that the VDC sys-
tem is working properly.
• Adjust your speed and driving according to the road conditions.
For additional information, refer to “Vehicle Dy-
namic Control (VDC) warning light” and “Vehicle
Dynamic Control (VDC) OFF indicator light” in
the “Instruments and controls” section of this
manual.
If a malfunction occurs in the system, the
warning illuminates in the lower display. The VDC
system automatically turns off when this warning
light is lit.
The VDC OFF switch is used to turn off the VDC
system. The VDC OFF indicator
illuminates
to indicate that the VDC system is off. When the
VDC switch is used to turn off the system, the
VDC system still operates to prevent one drive
wheel from slipping by transferring power to a
non slipping wheel. The
flashes if this
occurs. All other VDC functions are off and the
warning will not flash. The VDC System is automatically reset to ON when the power switch
is placed in the OFF position then back to the ON
position.
The computer has a built-in diagnostic feature
that tests the system each time you start the EV
and move the vehicle forward or in reverse at a
slow speed. When the self-test occurs, you may
hear a “clunk” noise and/or feel a pulsation in the
brake pedal. This is normal and is not an indica-
tion of a malfunction.
WARNING
• The VDC system is designed to help the driver maintain stability but does
not prevent accidents due to abrupt
steering operation at high speeds or
by careless or dangerous driving tech-
niques. Reduce vehicle speed and be
especially careful when driving and
cornering on slippery surfaces and al-
ways drive carefully.
• Do not modify the vehicle’s suspen- sion. If suspension parts such as shock
absorbers, struts, springs, stabilizer
bars, bushings and wheels are not
NISSAN recommended for your ve-
hicle or are extremely deteriorated the
VDC system may not operate properly.

REMOVING SPOTS
Remove tar and oil spots, industrial dust, insects,
and tree sap as quickly as possible from the paint
surface to avoid lasting damage or staining. Spe-
cial cleaning products are available at a NISSAN
certified LEAF dealer or any automotive acces-
sory stores.
UNDERBODY
In areas where road salt is used in winter, the
underbody must be cleaned regularly. This will
prevent dirt and salt from building up and causing
the acceleration of corrosion on the underbody
and suspension. Before the winter period and
again in the spring, the underseal must be
checked and, if necessary, re-treated.
GLASS
Use glass cleaner to remove smoke and dust film
from the glass surfaces. It is normal for glass to
become coated with a film after the vehicle is
parked in the hot sun. Glass cleaner and a soft
cloth will easily remove this film.
CAUTION
When cleaning the inside of the windows,
do not use sharp-edged tools, abrasive cleaners or chlorine-based disinfectant
cleaners. They could damage the electri-
cal conductors, radio antenna elements
or rear window defroster elements.
SOLAR CELL MODULE (IF SO
EQUIPPED)
The solar cell uses a plastic cover. When clean-
ing the cell:
• Do not polish the solar cell using a dry cloth or a
wax that contains a compound. Doing so may
strip off the hard coating.
• In order to maintain the solar cell’s effective- ness, be sure to remove any leaves or dirt from
the surface of the cell.
WHEELS
Wash the wheels when washing the vehicle to
maintain their appearance.
• Clean the inner side of the wheels when thewheel is changed or the underside of the vehicle
is washed.
• Inspect wheel rims regularly for dents or corro- sion. Such damage may cause loss of pressure
or poor seal at the tire bead. • NISSAN recommends that the road wheels be
waxed to protect against road salt in areas
where it is used during winter.
CAUTION
Do not use abrasive cleaners when wash-
ing the wheels.
Aluminum alloy wheels (if so
equipped)
Wash regularly with a sponge dampened in a
mild soap solution, especially during winter
months in areas where road salt is used. Salt
could discolor the wheels if not removed.
CAUTION
Follow the directions below to avoid
staining or discoloring the wheels:
• Do not use a cleaner that uses strong acid or alkali contents to clean the
wheels.
• Do not apply wheel cleaners to the wheels when they are hot. The wheel
temperature should be the same as
ambient temperature.
• Rinse the wheel to completely remove the cleaner within 15 minutes after the
cleaner is applied.

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.
