2011 NISSAN ALTIMA HYBRID brake

WARNING
●Pull your vehicle off the road, put the
transmission in the P (Park) position,
apply the parking brake and turn the
Hybrid System off.
● Check to see if there are exposed high
voltage parts and cables. Never touch
the parts and cables. See “High voltage
components”, later in this section for
the locations of the high voltage parts
and cables.
● To avoid personal injury, do not touch
high voltage wiring, connectors and
high voltage parts (inverter unit, high
voltage battery etc.) .
● If exposed electric wires are visible in-
side or outside of your vehicle, an elec-
tric shock may occur. Never touch the
electric wires.
● Inspect the ground under the vehicle. If
liquid has leaked onto the ground, the
fuel system may have been damaged.
Leave the vehicle as soon as possible. ●
Never touch fluid leaks inside or out-
side the vehicle. The leak may be strong
alkaline electrolyte from the high volt-
age battery. If it contacts your skin or
eyes, wash it off immediately with a
large amount of water or if possible,
boric acid solution. Get immediate
medical attention to help avoid serious
injury.
● If a fire occurs in the hybrid vehicle,
leave the vehicle as soon as possible.
Never use a fire extinguisher that is not
meant for use on electric fires. Using
even a small amount of water may be
also dangerous.
● If your vehicle needs to be towed, do it
with the front wheels raised. If the front
wheels are on the ground when towing,
the traction motor may generate elec-
tricity. This may damage the Hybrid Sys-
tem components and cause a fire.
EMERGENCY SHUT OFF SYSTEM
The emergency shut off system automatically
turns off the high voltage current in certain frontal
collisions. This is to minimize the risk of electrical
short circuits. If the system activates, your vehicle
will not restart. To restart the Hybrid System,
contact a NISSAN dealer. The Hybrid System monitors the status of power
being sent to the traction motor and the battery
state of charge. The status is shown on the hybrid
power meter and high voltage battery status me-
ter. System status can also be shown on the
navigation system display (if so equipped) when
the screen is in the Energy Flow mode or
energy/fuel history mode.

HEV OverviewHEV-3

Place the ignition switch in the ON position.
Depress the brake pedal and push the ignition
switch when the transmission is in the P (Park)
position to start the Hybrid System.
The READY light illuminates indicating that the
vehicle is ready to be driven. If the ambient tem-
perature is low, the READY may flash and may
take time until the READY light stays on. For
details, see “Starting the Hybrid System” in the
“Starting and driving” section of this manual.
As long as the READY light remains on you can
drive your vehicle using the traction motor even
though the gasoline engine may not be running.Drive your vehicle with smooth accelera-
tion and deceleration.
● While driving, energy is recovered through
the regenerative brake as the vehicle decel-
erates. However, for most efficient use, do
not accelerate or decelerate your vehicle
more than necessary.
● Avoid abrupt acceleration and deceleration.
● The power of the high voltage battery can be
checked on the high voltage battery status
meter. See “High voltage battery status me-
ter” in this section for details. Gradual or
non-abrupt acceleration and deceleration
will make more effective use of the traction
motor without having to use gasoline engine
power.
● When parking, be sure to place the shift
selector in the P (Park) position. While driv-
ing, place the shift selector in the D (Drive)
position.
● The Hybrid System recharges the high volt-
age battery as necessary. However, the Hy-
brid System can not charge the high voltage
battery when the transmission is in the N
(Neutral) position even if the engine is run-
ning. ●
If the high voltage battery becomes dis-
charged, the engine will run for a longer
period of time. Do not keep the transmission
in the N (Neutral) position with the system in
the ready mode.
NOTE:
The gasoline engine starts and stops auto-
matically. It may stop during low load driv-
ing, deceleration or when the vehicle is
stopped.
As long as the READY light remains on, you
can drive your vehicle using the traction
motor even with the gasoline engine
stopped.
The gasoline engine may not stop auto-
matically in the following conditions: ● During gasoline engine warm-up.
● During high voltage battery charging.
● During high or low high voltage battery
temperature.

HEV OverviewHEV-7

acceleration also consumes high voltage battery
power, resulting in poor acceleration. Battery
power can be restored by driving at a constant
speed.
When you put the shift selector in the B (Brake)
position and take your foot off the accelerator
pedal, engine braking will be applied. However,
during high speed driving you may feel that en-
gine braking is less effective than that of an
ordinary vehicle. This is normal.
Because the vehicle is powered by both the
gasoline engine and the traction motor, you may
hear a sound coming from the engine compart-
ment, high voltage battery, transmission or the
regenerative brakes. When the gasoline engine
starts and stops with the Hybrid System on, you
may feel a vibration. When accelerating rapidly,
the engine noise may rise. A noise may also be
heard while braking. These are normal character-
istics of the hybrid vehicle.An air vent is located on the rear parcel shelf
A
to cool the high voltage battery. If the vent is
covered, the battery will overheat resulting in
reduced output performance of the Hybrid Sys-
tem.
You may hear the noise of the cooling fan from the
air vent.CAUTION
Do not place objects over or into the air
vent. The high voltage battery may over-
heat and be damaged.

WARNING
●Your brake system may not be working
properly if the warning light is on. Driv-
ing could be dangerous. If you judge it
to be safe, drive carefully to the nearest
service station for repairs. Otherwise,
have your vehicle towed because driv-
ing it could be dangerous.
● Pressing the brake pedal with the igni-
tion switch placed in the OFF position
and/or a low brake fluid level may in-
crease your stopping distance and
braking will require greater pedal effort
as well as pedal travel.
● If the brake fluid level is below the
MINIMUM or MIN mark on the brake
fluid reservoir, do not drive until the
brake system has been checked at a
NISSAN dealer. ●
Your brake system may not be working
properly if both the brake warning light
and electronically controlled brake sys-
tem warning light come on when the
Hybrid System is in READY mode and
the parking brake is not applied. Driving
could be dangerous. If you judge it to be
safe, drive carefully to the nearest ser-
vice station for repairs. Otherwise, have
your vehicle towed because driving
could be dangerous.
Anti-lock Braking System (ABS) warning
indicator
When the parking brake is released and the
brake fluid level is sufficient, if both the brake
warning light and the Anti-lock Braking System
(ABS) warning light illuminate, it may indicate the
ABS is not functioning properly. Have the brake
system checked, and if necessary, repaired by a
NISSAN dealer promptly. Avoid high-speed driv-
ing and abrupt braking. (See “Anti-lock Braking
System (ABS) warning light” in this section.)
12–volt battery charge warning light
If this light comes on while the Hybrid System is
running, it may indicate the 12-volt battery charg-
ing system is not functioning properly. See a
NISSAN dealer immediately.
CAUTION
The charging system may not be function-
ing properly if the charge warning light
comes on while the Hybrid System is run-
ning. The Hybrid System will stop operat-
ing when the 12-volt battery becomes dis-
charged. Immediately stop the vehicle in a
safe place and contact your NISSAN
dealer.
