2008 NISSAN ALTIMA HYBRID cooling

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 selector lever 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
sA
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.

cThe air conditioner cooling function op-
erates only when the Hybrid System is
in the READY mode. Even if the Hybrid
System is in the READY mode, the cool-
ing function will not operate if the high
voltage battery becomes discharged.cDo not leave children or adults who
would normally require the assistance
of others alone in your vehicle. Pets
should also not be left alone. They
could accidentally injure themselves or
others through inadvertent operation of
the vehicle. Also, on hot, sunny days,
temperatures in a closed vehicle could
quickly become high enough to cause
severe or possibly fatal injuries to
people or animals.
cDo not use the recirculation mode for
long periods as it may cause the interior
air to become stale and the windows to
fog up.
Push the ignition switch to the ON position and
wait for the READY light to illuminate, then oper-
ate the controls to activate the air conditioner.
AUTOMATIC OPERATION
Cooling or heating (auto)
This mode may be normally used all year round as
the system automatically works to keep a con-
stant temperature. Air flow distribution and fan
speed are also controlled automatically.
1. Push the AUTO button on.

FREEING A FROZEN DOOR LOCK
To prevent a door lock from freezing, apply de-
icer through the key hole. If the lock becomes
frozen, heat the key before inserting it into the key
hole or use the remote keyless entry keyfob (if so
equipped) .
ANTI-FREEZE
In the winter when it is anticipated that the tem-
perature will drop below 32°F (0°C) , check the
anti-freeze to assure proper winter protection.
For details, see “Engine cooling system” and
“Inverter cooling system” in the “Maintenance
and do-it-yourself” section of this manual.
DRAINING OF COOLANT WATER
If the vehicle is to be left outside without anti-
freeze, drain the cooling system, including the
engine block. Refill before operating the vehicle.
For details, see “Changing engine coolant” and
“Changing inverter coolant” in the “Maintenance
and do-it-yourself” section of this manual.
TIRE EQUIPMENT
1. SUMMER tires have a tread designed to
provide superior performance on dry pave-
ment. However, the performance of these
tires will be substantially reduced in snowy
and icy conditions. If you operate your ve-
hicle on snowy or icy roads, NISSAN recom-
mends the use of MUD & SNOW or ALL
SEASON TIRES on all four wheels. Please
consult a NISSAN dealer for the tire type,
size, speed rating and availability informa-
tion.
2. 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.
3. Tire chains may be used. For details, see
“Tire chains” in the “Maintenance and do-it-
yourself” section of this manual.
SPECIAL WINTER EQUIPMENT
It is recommended that the following items be
carried in the vehicle during winter:
cA scraper and stiff-bristled brush to remove
ice and snow from the windows and wiper
blades.
cA sturdy, flat board to be placed under the
jack to give it firm support.
cA shovel to dig the vehicle out of snowdrifts.
cExtra window washer fluid to refill the reser-
voir tank.
DRIVING ON SNOW OR ICE
WARNING
cWet ice (32°F, 0°C and freezing rain) ,
very cold snow or ice can be slick and
very hard to drive on. The vehicle will
have much less traction or “grip” under
these conditions. Try to avoid driving on
wet ice until the road is salted or
sanded.
cWhatever the condition, drive with cau-
tion. Accelerate and slow down with
care. If accelerating or downshifting too
fast, the drive wheels will lose even
more traction.

CAUTION
Hybrid models cannot be push-started or
tow-started. Attempting to do so may
cause electrical or transmission damage.If your vehicle is overheating (indicated by the
high temperature warning light) , or if you feel a
lack of engine power, detect abnormal noise, etc.
take the following steps.
WARNING
cDo not continue to drive if your vehicle
overheats. Doing so could cause engine
damage or a vehicle fire.
cTo avoid the danger of being scalded,
never remove the radiator cap while the
engine and/or inverter is still hot. When
the radiator cap is removed, pressur-
ized hot water will spurt out, possibly
causing serious injury.
cDo not open the hood if steam is com-
ing out.
1. Move the vehicle safely off the road, apply
the parking brake and move the shift lever to
P (Park) .
Do not turn the Hybrid System off.
2. Turn off the air conditioner. Open all the
windows, move the heater or air conditioner
temperature control to maximum hot and fan
control to high speed.3. Get out of the vehicle. Look and listen for
steam or coolant escaping from the radiator
before opening the hood. (If steam or cool-
ant is escaping, turn the Hybrid System off.)
Do not open the hood further until no steam
or coolant can be seen.
4. Open the engine hood.
WARNING
If steam or water is coming from the en-
gine and/or inverter, stand clear to pre-
vent getting burned.
5. Visually check drive belts for damage or
looseness. Also check if the cooling fan is
running. The radiator hoses and radiator
should not leak water. If coolant is leaking,
the water pump belt is missing or loose, or
the cooling fan does not run, turn the Hybrid
System off.
WARNING
Be careful not to allow your hands, hair,
jewelry or clothing to come into contact
with, or get caught in, engine belts or the

When performing any inspection or maintenance
work on your vehicle, always take care to prevent
serious accidental injury to yourself or damage to
the vehicle. The following are general precau-
tions which should be closely observed.
WARNING
cThis vehicle has high voltage DC and AC
systems as well as a 12-volt system. DC
and AC high voltage is very dangerous
and can cause severe burns and electric
shock that may result in serious injury
or death.
cNever touch, disassemble, remove or
replace the high voltage parts, cables
and their connectors. High voltage
cables are orange. Touching, disassem-
bling, removing or replacing those parts
and cables can cause severe burns or
electric shock that may result in serious
injury or death.cNever try to remove the service discon-
nect located in the trunk on the lower
right-hand side. The service disconnect
is used only when the vehicle is ser-
viced by trained technicians wearing
personal protection equipment and is
part of the high voltage system. Touch-
ing the service disconnect can cause
severe burns or electric shock that may
result in serious injury or death.
cThe hybrid system uses high voltage up
to 650 V. The system can be hot while
and after starting. Be careful of both the
high voltage and the high temperature.
Obey the caution labels attached to the
vehicle.
cPark the vehicle on a level surface, ap-
ply the parking brake securely and
block the wheels to prevent the vehicle
from moving. Move the selector lever to
P (Park) .
cBe sure the ignition switch is in the OFF
or LOCK position when performing any
parts replacement or repairs.
cNever leave the engine or the transmis-
sion related component harness con-
nector disconnected while the ignition
switch is in the ON position.cNever connect or disconnect the battery
or any transistorized component while
the ignition switch is in the ON position.
cYour vehicle is equipped with an auto-
matic engine cooling fan. It may come
on at any time without warning, even if
the ignition key is in the OFF position
and the engine is not running. To avoid
injury, always disconnect the negative
battery cable before working near the
fan.
cThe engine can start at any time without
warning when the Hybrid System is in
the READY mode. If you must work with
the Hybrid System in the READY mode,
keep your hands, clothing, hair and
tools away from fans, belts and any
other parts that can move.
cIt is advisable to secure or remove any
loose clothing and remove any jewelry,
such as rings, watches, etc. before
working on your vehicle.
cAlways wear eye protection whenever
you work on your vehicle.
cIf you must run the engine in an en-
closed space such as a garage, be sure
there is proper ventilation for exhaust
gases to escape.
