2011 NISSAN ALTIMA HYBRID maintenance

c. You notice a change in the sound ofthe exhaust system.
d. You have had an accident involving damage to the exhaust system, un-
derbody, or rear of the vehicle.
THREE-WAY CATALYST
The three-way catalyst is an emission control
device installed in the exhaust system. Exhaust
gases in the three-way catalyst are burned at
high temperatures to help reduce pollutants.
WARNING
●The exhaust gas and the exhaust sys-
tem are very hot. Keep people, animals
or flammable materials away from the
exhaust system components.
● Do not stop or park the vehicle over
flammable materials such as dry grass,
waste paper or rags. They may ignite
and cause a fire.
CAUTION
● Do not use leaded gasoline. Deposits
from leaded gasoline will seriously re-
duce the three-way catalyst’s ability to
help reduce exhaust pollutants. ●
Keep your engine tuned up. Malfunc-
tions in the ignition, fuel injection, or
electrical systems can cause overrich
fuel flow into the three-way catalyst,
causing it to overheat. Do not keep driv-
ing if the engine misfires, or if notice-
able loss of performance or other un-
usual operating conditions are
detected. Have the vehicle inspected
promptly by a NISSAN dealer.
● Avoid driving with an extremely low fuel
level. Running out of fuel could cause
the engine to misfire, damaging the
three-way catalyst.
● Do not race the engine while warming it
up.
● Do not push or tow your vehicle to start
the engine.
TIRE PRESSURE MONITORING
SYSTEM (TPMS)
Each tire, including the spare (if provided) ,
should be checked monthly when cold and in-
flated to the inflation pressure recommended by
the vehicle manufacturer on the vehicle placard
or tire inflation pressure label, located in the
driver’s door opening. (If your vehicle has tires of a different size than the
size indicated on the vehicle placard or tire infla-
tion pressure label, you should determine the
proper tire inflation pressure for those tires.)
As an added safety feature, your vehicle has been
equipped with a Tire Pressure Monitoring System
(TPMS) that illuminates a low tire pressure telltale
when one or more of your tires is significantly
under-inflated. Accordingly, when the low tire
pressure telltale illuminates, you should stop and
check all 4 tires as soon as possible, and inflate
them to the proper pressure. Driving on a signifi-
cantly under-inflated tire causes the tire to over-
heat and can lead to tire failure. Under-inflation
also reduces fuel efficiency and tire tread life, and
may affect the vehicle’s handling and stopping
ability.
Please note that the TPMS is not a substitute for
proper tire maintenance, and it is the driver’s
responsibility to maintain correct tire pressure,
even if under-inflation has not reached the level to
trigger illumination of the TPMS low tire pressure
telltale.
Your vehicle has also been equipped with a
TPMS malfunction indicator to indicate when the
system is not operating properly. The TPMS mal-
function indicator is combined with the low tire
pressure telltale. When the system detects a
malfunction, the telltale will flash for approxi-
Starting and driving5-3

avoid driving when tired. Never drive when under
the influence of alcohol or drugs (including pre-
scription or over-the-counter drugs which may
cause drowsiness) . Always wear your seat belt
as outlined in the “Safety – Seats, seat belts and
supplemental restraint system” section of this
manual, and also instruct your passengers to do
so.
Seat belts help reduce the risk of injury in colli-
sions and rollovers.In a rollover crash, an
unbelted or improperly belted person is
significantly more likely to be injured or
killed than a person properly wearing a
seat belt.
OFF-ROAD RECOVERY
If the right side or left side wheels leave the road
surface, maintain control of the vehicle by follow-
ing the procedure below. Please note that this
procedure is only a general guide. The vehicle
must be driven as appropriate based on the con-
ditions of the vehicle, road and traffic.
1. Remain calm and do not overreact.
2. Do not apply the brakes.
3. Maintain a firm grip on the steering wheel with both hands and try to hold a straight
course. 4. When appropriate , slowly release the accel-
erator pedal to gradually slow the vehicle.
5. If there is nothing in the way, steer the ve- hicle to follow the road while vehicle speed
is reduced. Do not attempt to drive the ve-
hicle back onto the road surface until vehicle
speed is reduced.
6. When it is safe to do so, gradually turn the steering wheel until both tires return to the
road surface. When all tires are on the road
surface, steer the vehicle to stay in the ap-
propriate driving lane.
● If you decide that it is not safe to return the
vehicle to the road surface based on vehicle,
road or traffic conditions, gradually slow the
vehicle to a stop in a safe place off the road.RAPID AIR PRESSURE LOSS
Rapid air pressure loss or a “blow-out” can occur
if the tire is punctured or is damaged due to
hitting a curb or pothole. Rapid air pressure loss
can also be caused by driving on under-inflated
tires.
Rapid air pressure loss can affect the handling
and stability of the vehicle, especially at highway
speeds. Help prevent rapid air pressure loss by maintain-
ing the correct air pressure and visually inspect
the tires for wear and damage. See “Wheels and
tires” in the “Maintenance and do-it-yourself”
section of this manual. If a tire rapidly loses air
pressure or “blows-out” while driving, maintain
control of the vehicle by following the procedure
below. Please note that this procedure is only a
general guide. The vehicle must be driven as
appropriate based on the conditions of the ve-
hicle, road and traffic.
WARNING
The following actions can increase the
chance of losing control of the vehicle if
there is a sudden loss of tire air pressure.
Losing control of the vehicle may cause a
collision and result in personal injury.
●
The vehicle generally moves or pulls in
the direction of the flat tire.
● Do not rapidly apply the brakes.
● Do not rapidly release the accelerator
pedal.
● Do not rapidly turn the steering wheel.
1. Remain calm and do not over react.

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 function on
the Intelligent Key.
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 toprovide 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:
● A scraper and stiff-bristled brush to remove
ice and snow from the windows and wiper
blades.
● A sturdy, flat board to be placed under the
jack to give it firm support. ●
A shovel to dig the vehicle out of snowdrifts.
● Extra washer fluid to refill the windshield-
washer fluid reservoir.
DRIVING ON SNOW OR ICE
WARNING
● Wet 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.
● Whatever 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.
● Allow more stopping distance under
these conditions. Braking should be
started sooner than on dry pavement.
● Allow greater following distances on
slippery roads.

Installing the spare tire
The spare tire is designed for emergency
use. See specific instructions under the
heading “Wheels and tires” in the “Mainte-
nance and do-it-yourself” section of this
manual.1. Clean any mud or dirt from the surface be- tween the wheel and hub.
2. Carefully put the spare tire on and tighten the wheel nuts finger tight.
3. With the wheel nut wrench, tighten wheel nuts alternately and evenly as illustrated until
they are tight. 4. Lower the vehicle slowly until the tire
touches the ground. Then, with the wheel
nut wrench, tighten the wheel nuts securely
in the sequence illustrated (
A,B,C,D,
E) . Lower the vehicle completely.
WARNING
●Incorrect wheel nuts or improperly
tightened wheel nuts can cause the
wheel to become loose or come off.
This could cause an accident.
● Do not use oil or grease on the wheel
studs or nuts. This could cause the nuts
to become loose.
● Retighten the wheel nuts when the ve-
hicle has been driven for 600 miles
(1,000 km) (also in cases of a flat tire,
etc.) .
As soon as possible, tighten the wheel nuts
to the specified torque with a torque
wrench.
Wheel nut tightening torque: 83 ft-lb (113 N·m)
The wheel nuts must be kept tightened to
specification at all times. It is recom-
mended that wheel nuts be tightened to
specifications at each lubrication interval. Adjust tire pressure to the COLD pressure.
COLD pressure: After vehicle has been
parked for three hours or more or driven
less than 1 mile (1.6 km) .
COLD tire pressures are shown on the tire
and loading information label affixed to the
driver side center pillar.
5. Securely store the flat tire and jacking equip- ment in the vehicle.
6. Place the spare tire cover and the trunk floor carpeting over the damaged tire.
7. Close the trunk.
WARNING
● Always make sure that the spare tire
and jacking equipment are properly se-
cured after use. Such items can become
dangerous projectiles in an accident or
sudden stop.
● The spare tire is designed for emer-
gency use. See specific instructions un-
der the heading “Wheels and tires” in
the “Maintenance and do-it-yourself”
section of this manual.

6-6In case of emergency

WARNING
●If the Hybrid System stops operating
while driving, the power assist for the
brakes and steering will not work. Brak-
ing and steering will be harder.
● If the Hybrid System stops operating
while driving, do not open any door until
the vehicle comes to a complete stop.
Opening a door will lock the steering
wheel. This may cause the driver to lose
control of the vehicle and could result in
serious vehicle damage or personal
injury.
The Hybrid System may stop operating while
driving if the high voltage battery becomes dis-
charged, the 12-volt battery becomes dis-
charged or the fuel tank is empty. If the Hybrid
System stops operating while driving, perform
the following: 1. Reduce your speed gradually. Pull to the side of the road to a safe area.
2. Turn on the hazard warning flashers.
3. Set the “POWER” switch at ACC or OFF, and try to start the Hybrid System.
4. If the Hybrid System will not start, see “Ve- hicle does not start” in this section. Before attempting to jump start the vehicle, make
sure the fuel tank is not empty and the correct
starting procedure is followed. See “Starting the
Hybrid System” in the “Starting and driving” sec-
tion. Do not drive the vehicle on battery power
only if the fuel tank is empty. The high voltage
battery will become discharged and the Hybrid
System will turn off.
CONFIRM BATTERY IS
DISCHARGED
Confirm the battery is discharged by pushing the
ignition switch to the ON position. Confirm the
instrument cluster or head lights come on at the
normal brightness levels or that other accesso-
ries such as the audio system come on. Push the
ignition switch to turn the Hybrid System on.
● If the lights do not dim or the accessories do
not turn off, see “Emergency start” in this
section.
● If the lights become dim or the accessories
turn off, check the following:
1. Check that the 12-volt battery terminals are tight and clean. See “12-volt Battery” in the
“Maintenance and do-it-yourself” section.
The battery is located on the right hand side
of the trunk behind an access panel. If the
12-volt battery terminals are loose, contact
your NISSAN dealer. 2. If the 12-volt battery terminals are tight and
clean, try to jump start the vehicle. See
“Jump starting” in this section.
EMERGENCY START
When the Hybrid System cannot be started, the
following procedure can be used if the Hybrid
System and “POWER” switch function normally:
1. Put the transmission in P (Park) position.
2. Push the ignition switch to the ACC posi- tion.
3. Depress the brake pedal.
4. Push and hold the ignition switch for about 15 seconds. Even if the Hybrid System
starts using this procedure, the system may
be malfunctioning. Do not continue to use
this emergency procedure to start the sys-
tem. Have the vehicle checked by your
NISSAN dealer.
If the Hybrid System still does not start, contact
you NISSAN dealer.

●Use only genuine NISSAN floor mats
specifically designed for use in your ve-
hicle model. See your NISSAN dealer
for more information.
● Properly position the mats in the floor-
well using the floor mat positioning aid.
See Floor mat positioning aid in this
section.
The use of genuine NISSAN floor mats can ex-
tend the life of your vehicle carpet and make it
easier to clean the interior. Mats should be main-
tained with regular cleaning and replaced if they
become excessively worn.
Floor mat positioning aid
This vehicle includes a front floor mat bracket to
act as a floor mat positioning aid. Genuine
NISSAN floor mats have been specially designed
for your vehicle model. The driver’s and passen-
ger’s side floor mats have a grommet hole incor-
porated in them. Position the mat by placing the
floor mat bracket hook through the floor mat
grommet hole while centering the mat in the
floorwell.
Periodically check to make certain the mats are
properly positioned.
SEAT BELTS
The seat belts can be cleaned by wiping them
with a sponge dampened in a mild soap solution.
Allow the belts to dry completely in the shade
before using them. See “Seat belt maintenance”
in the “Safety – Seats, seat belts and supplemen-
tal restraint system” section of this manual.
WARNING
Do not allow wet seat belts to roll up in the
retractor. NEVER use bleach, dye or
chemical solvents to clean the seat belts,
since these materials may severely
weaken the seat belt webbing.
