snow chains NISSAN SENTRA 2009 Owner´s Manual

The brake system has two separate hydraulic
circuits. If one circuit malfunctions, you will still
have braking at 2 wheels.
BRAKE PRECAUTIONS
Vacuum assisted brakes
The brake booster aids braking by using engine
vacuum. If the engine stops, you can stop the
vehicle by depressing the brake pedal. However,
greater foot pressure on the brake pedal will be
required to stop the vehicle and stopping dis-
tance will be longer.
Using the brakes
Avoid resting your foot on the brake pedal while
driving. This will overheat the brakes, wear out the
brake pads faster, and reduce gas mileage.
To help reduce brake wear and to prevent the
brakes from overheating, reduce speed and
downshift to a lower gear before going down a
slope or long grade. Overheated brakes may
reduce braking performance and could result in
loss of vehicle control.
WARNING
●While driving on a slippery surface, be
careful when braking, accelerating or
downshifting. Abrupt braking or accel-
erating could cause the wheels to skid
and result in an accident.
●If the engine is not running or is turned
off while driving, the power assist for
the brakes will not work. Braking will be
harder.
Wet brakes
When the vehicle is washed or driven through
water, the brakes may get wet. As a result, your
braking distance will be longer and the vehicle
may pull to one side during braking.
To dry the brakes, drive the vehicle at a safe
speed while lightly pressing 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 function correctly.
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
drum/rotors are replaced, in order to assure the
best brake performance.This procedure is described in the vehicle service
manual and can be performed by a NISSAN
dealer.
ANTI-LOCK BRAKING SYSTEM
(ABS) (if so equipped)
WARNING
●The Anti-lock Braking System (ABS) is a
sophisticated device, but it cannot pre-
vent accidents resulting from careless
or dangerous driving techniques. It can
help maintain vehicle control during
braking on slippery surfaces. Remem-
ber that stopping distances on slippery
surfaces will be longer than on normal
surfaces 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 vehicle in front
of you. Ultimately, the driver is respon-
sible for safety.
●Tire type and condition may also affect
braking effectiveness.
– When replacing tires, install the
specified size of tires on all four
wheels.

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” in the
“Maintenance and do-it-yourself” section of this
manual.
BATTERY
If the battery is not fully charged during extremely
cold weather conditions, the battery fluid may
freeze and damage the battery. To maintain maxi-
mum efficiency, the battery should be checked
regularly. For details, see “Battery” in the “Main-
tenance 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” 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:
●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 window washer fluid to refill the reser-
voir tank.
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.

CAUTION
●Tow chains or cables must be attached
only to the main structural members of
the vehicle or the towing hooks (if so
equipped) . Otherwise, the vehicle body
will be damaged.
●Use the towing hook (if so equipped)
only to free a vehicle stuck in sand,
snow, mud, etc. Never tow the vehicle
for a long distance using only the tow-
ing hook.
●The towing hook is under tremendous
force when used to free a stuck vehicle.
Never pull the hook at an angle.
●Always pull the cable straight out from
the front or rear of the vehicle.
●Pulling devices should be routed so
they do not touch any part of the sus-
pension, steering, brake or cooling
systems.
●Pulling devices such as ropes or canvas
straps are not recommended for use in
vehicle towing or recovery.
Pulling a stuck vehicle
Front (if so equipped)
Do not use the hook to tow the vehicle.Rear (if so equipped)
Do not use the hook to tow the vehicle.
Rocking a stuck vehicle
If your vehicle is stuck in sand, snow, mud, etc.,
use the following procedure:
1. Make sure the area in front and behind the
vehicle is clear of obstructions.
2. Turn the steering wheel right and left to clear
an area around the front tires.

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.
TIRE CHAINS
CAUTION
Tire chains/cables should not be installed
on P225/45R17 size tires. Installation of
the tire chains/cables on P225/45R17 size
tires will cause damage to the vehicle. If
you plan to use tire chains/cables, you
should install P205/55R16 size tires on
your vehicle.
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 de-
signed to meet the minimum clearances between
the tire and the closest vehicle suspension or
body component required to accommodate the
use of a winter traction device (tire chains or
cables) . The minimum clearances are determined
using the factory equipped tires. Other types may
damage your vehicle. Use chain tensioners whenrecommended 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 pos-
sibility 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 perfor-
mance may be adversely affected.
Tire chains must be installed only on the
front wheels and not on the rear wheels.
Never install tire chains on a TEMPORARY USE
ONLY spare tire.
Do not use tire chains on dry roads. Driving with
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 7,500 miles (12,000 km) .
See “Flat tire” in the “In case of emer-
gency” section of this manual for tire re-
placing procedures.
As soon as possible, tighten the
wheel nuts to the specified torque
with a torque wrench.

Care of wheels
●Wash the wheels when washing the vehicle
to maintain their appearance.
●Clean the inner side of the wheels when the
wheel is changed or the underside of the
vehicle is washed.
●Do not use abrasive cleaners when washing
the wheels.
●Inspect wheel rims regularly for dents or
corrosion. Such damage may cause loss of
pressure or poor seal at the tire bead.
●NISSAN recommends waxing the road
wheels to protect against road salt in areas
where it is used during winter.
Spare tire (TEMPORARY USE ONLY
spare tire)
Observe the following precautions if the TEM-
PORARY USE ONLY spare tire must be used.
Otherwise, your vehicle could be damaged or
involved in an accident:
WARNING
●The spare tire should be used for emer-
gency use only. It should be replaced
with the standard tire at the first oppor-
tunity to avoid possible tire or differen-
tial damage.
●Drive carefully while the TEMPORARY
USE ONLY spare tire is installed. Avoid
sharp turns and abrupt braking while
driving.
●Periodically check spare tire inflation
pressure. Always keep the pressure of
the TEMPORARY USE ONLY spare tire
at 60 psi (420 kPa, 4.2 bar) .
●With the TEMPORARY USE ONLY spare
tire installed do not drive the vehicle at
speeds faster than 50 MPH (80 km/h) .
●When driving on roads covered with
snow or ice, the TEMPORARY USE
ONLY spare tire should be used on the
rear wheels and the original tire used
on the front wheels (drive wheels) . Use
tire chains only on the front (original)
tires.●Tire tread of the TEMPORARY USE
ONLY spare tire will wear at a faster rate
than the standard tire. Replace the
spare tire as soon as the tread wear
indicators appear.
●Do not use the spare tire on other
vehicles.
●Do not use more than one spare tire at
the same time.
●Do not tow a trailer when the TEMPO-
RARY USE ONLY spare tire is installed.
CAUTION
●Do not use tire chains on a TEMPO-
RARY USE ONLY spare tire. Tire chains
will not fit properly and may cause dam-
age to the vehicle.
●Because the TEMPORARY USE ONLY
spare tire is smaller than the original
tire, ground clearance is reduced. To
avoid damage to the vehicle, do not
drive over obstacles. Also, do not drive
the vehicle through an automatic car
wash since it may get caught.
