NOISE AND VIBRATION
You might experience the following noise
or vibration as a normal characteristic of
this vehicle:
• Traction motor noise from the motorcompartment.
• Water pump and radiator fan noise while charging.
• Compressor and radiator fan noise when the Climate Ctrl. Timer or remote climate
control (models with Navigation System)
is used.
• Relay operation noise and vibration at start-up and shut-down of the EV system
(power switch placed in the ON and OFF
position).
• Approaching Vehicle Sound for Pedestri- ans (VSP). This section provides a brief explanation
for the most important LEAF functions. For
additional information, refer to the specific
sections of this manual for detailed expla-
nations of the vehicle features and
operation.
CHARGING THE LI-ION BATTERY
WARNING
The EV system uses a high voltage cur-
rent. Failure to follow the proper han-
dling instructions may cause serious
injury or death. Be sure to read the
“Charging” section and follow the pro-
cedures and guidelines described.

EV-12EV Overview

Wet brakes
When the vehicle is washed or driven
through water, the brakes may get wet. As
a result, the braking distance will be longer
and the vehicle may pull to one side during
braking.
To dry brakes, drive the vehicle at a safe
speed while lightly tapping the brake pedal
to heat up the brakes. Do this until the
brakes return to normal. Avoid driving the
vehicle at high speeds until the brakes
have dried.
Parking brake break-in
Break in the parking brake shoes whenever
the stopping effect of the parking brake is
weakened or whenever the parking brake
shoes and/or rotors are replaced, in order
to assure the best braking performance.
This procedure is described in the Genuine
NISSAN Service Manual, and it can be per-
formed by a certified repair facility. It is rec-
ommended that you visit a NISSAN certi-
fied LEAF dealer.
ANTI-LOCK BRAKING SYSTEM (ABS)
WARNING
• The ABS is a sophisticated device, but
it cannot prevent accidents resulting
from careless or dangerous driving
techniques. It can help maintain ve-
hicle control during braking on slip-
pery surfaces. Remember that stop-
ping distances on slippery surfaces
will be longer than on normal sur-
faces even with ABS. Stopping dis-
tances may also be longer on rough,
gravel or snow covered roads, or if
you are using tire chains. Always
maintain a safe distance from the ve-
hicle in front of you. Ultimately, the
driver is responsible for safety.
• Tire type and condition may also af-
fect braking effectiveness.
– When replacing tires, install the
specified size of tires on all four
wheels.
– For additional information, see
“Wheels and tires” (P. 8-25). The ABS controls the brakes so the wheels
do not lock during hard braking or when
braking on slippery surfaces. The system
detects the rotation speed at each wheel
and varies the brake fluid pressure to pre-
vent each wheel from locking and sliding.
By preventing each wheel from locking, the
system helps the driver maintain steering
control and helps to minimize swerving
and spinning on slippery surfaces.
Using the system
Depress the brake pedal and hold it down.
Depress the brake pedal with firm steady
pressure, but do not pump the brakes. The
Anti-lock Braking System will operate to
prevent the wheels from locking up. Steer
the vehicle to avoid obstacles.
WARNING
Do not pump the brake pedal. Doing so
may result in increased stopping
distances.
