suspension NISSAN ALTIMA COUPE 2012 D32 / 4.G Owners Manual

When the VDC switch is used to turn off the
system, the VDC system still operates to prevent
one drive wheel from slipping by transferring
power to a non slipping drive wheel. The
indicator flashes if this occurs. All other VDC
functions are off and the
indicator will not
flash.
The VDC system is automatically reset to on
when the ignition switch is placed in the off
position then back to the on position.
The computer has a built in diagnostic feature
that tests the system each time you start the
engine and move the vehicle forward or in reverse
at a slow speed. When the self-test occurs, you
may hear a clunk noise and/or feel a pulsation in
the brake pedal. This is normal and is not an
indication of a malfunction.
WARNING
● The VDC system is designed to help the
driver maintain stability but does not
prevent accidents due to abrupt steer-
ing operation at high speeds or by care-
less or dangerous driving techniques.
Reduce vehicle speed and be especially
careful when driving and cornering on
slippery surfaces and always drive
carefully. ●
Do not modify the vehicle’s suspension.
If suspension parts such as shock ab-
sorbers, struts, springs, stabilizer bars,
bushings and wheels are not NISSAN
recommended for your vehicle or are
extremely deteriorated, the VDC system
may not operate properly. This could
adversely affect vehicle handling per-
formance, and the
indicator may
flash or both the
andindi-
cator lights may illuminate.
● If brake related parts such as brake
pads, rotors and calipers are not
NISSAN recommended or are extremely
deteriorated, the VDC system may not
operate properly and both the
and theindicator lights may
illuminate.
● If engine control related parts are not
NISSAN recommended or are extremely
deteriorated, both the
andindicator lights may illuminate. ●
When driving on extremely inclined sur-
faces such as higher banked corners,
the VDC system may not operate prop-
erly and the
indicator may flash or
both the
andindicator
lights may illuminate. Do not drive on
these types of roads.
● When driving on an unstable surface
such as a turntable, ferry, elevator or
ramp, the
indicator may flash or
both the
andindicator
lights may illuminate. This is not a mal-
function. Restart the engine after driv-
ing onto a stable surface.
● If wheels or tires other than the NISSAN
recommended ones are used, the VDC
system may not operate properly and
the
indicator may flash or both
the
andindicator lights may
illuminate.
● The VDC system is not a substitute for
winter tires or tire chains on a snow
covered road.

REMOVING SPOTS
Remove tar and oil spots, industrial dust, insects,
and tree sap as quickly as possible from the
surface of the paint to avoid lasting damage or
staining. Special cleaning products are available
at a NISSAN dealer or any automotive accessory
store.
UNDERBODY
In areas where road salt is used in winter, it is
necessary to clean the underbody regularly in
order to prevent dirt and salt from building up and
causing the acceleration of corrosion on the un-
derbody and suspension. Before the winter pe-
riod and again in the spring, the underseal must
be checked and, if necessary, retreated.
GLASS
When cleaning the rear window, it may be easier
to clean if the high-mounted stop light (if so
equipped) is removed first.
Be careful when removing the high-mounted
stop light to reduce the risk of damaging the
high-mounted stop light wires.
To remove the high-mounted stop light:
1Push toward rear of vehicle.
2Lift to remove.
The high-mounted stop light must be properly
reinstalled before driving your vehicle. Use glass cleaner to remove smoke and dust film
from the glass surfaces. It is normal for glass to
become coated with a film after the vehicle is
parked in the hot sun. Glass cleaner and a soft
cloth will easily remove this film.
CAUTION
When cleaning the inside of the windows,
do not use sharp-edged tools, abrasive
cleaners or chlorine-based disinfectant
cleaners. They could damage the electri-
cal conductors, radio antenna elements or
rear window defroster elements.
ALUMINUM ALLOY WHEELS (if so
equipped)
Wash the wheels regularly with a sponge damp-
ened in a mild soap solution, especially during
winter months in areas where road salt is used. If
not removed, road salt can discolor the wheels.
CAUTION
Follow the directions below to avoid
staining or discoloring the wheels:
●
Do not use a cleaner that uses strong
acid or alkali contents to clean the
wheels.

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
Only certain SAE class “S” tire chains can
be used on this vehicle. Using the wrong
Class “S” chains on this vehicle will cause
damage to the vehicle. If you plan to use
tire chains/cables, you should use a tire
chain that meets the minimum clearances
for 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 a tire chain that
is designed to provide the specified space
A
between the installed tire chain1and where the
tire meets the rim
2as shown on the chart.
Wheel size Minimum space required
16 in .7 in (17 mm)
17 in .2 in (4 mm)
18 in .2 in (4 mm)
A tire chain that provides the specified amount of
space will provide the necessary clearance be-
tween the tire and the closest vehicle suspension
or body component. The minimum clearances are
determined using the factory-equipped tires.
Other types may damage your vehicle. Use chain
tensioners when recommended 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 possibility of whipping action dam-
age 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 performance may be ad-
versely 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
tire chains in such conditions can cause damage
to the various mechanisms of the vehicle due to
some overstress.

WARNING
Never connect a trailer brake system di-
rectly to the vehicle brake system.
Pre-towing tips
●Be certain your vehicle maintains a level
position when a loaded and/or unloaded
trailer is hitched. Do not drive the vehicle if it
has an abnormal nose-up or nose-down
condition; check for improper tongue load,
overload, worn suspension or other possible
causes of either condition.
● Always secure items in the trailer to prevent
load shift while driving.
● Keep the cargo load as low as possible in
the trailer to keep the trailer center of gravity
low.
● Load the trailer so approximately 60% of the
trailer load is in the front half and 40% is in
the back half. Also make sure the load is
balanced side to side.
● Check your hitch, trailer tire pressure, ve-
hicle tire pressure, trailer light operation, and
trailer wheel lug nuts every time you attach a
trailer to the vehicle. ●
Be certain your rearview mirrors conform to
all federal, state or local regulations. If not,
install any mirrors required for towing before
driving the vehicle.
● Determine the overall height of the vehicle
and trailer so the required clearance is
known.
Trailer towing tips
In order to gain skill and an understanding of the
vehicle’s behavior, you should practice turning,
stopping and backing up in an area which is free
from traffic. Steering stability and braking perfor-
mance will be somewhat different than under
normal driving conditions.
● Always secure items in the trailer to prevent
load shift while driving.
● Lock the trailer hitch coupler with a pin or
lock to prevent the coupler from inadver-
tently becoming unlatched.
● Avoid abrupt starts, acceleration or stops.
● Avoid sharp turns or lane changes.
● Always drive your vehicle at a moderate
speed. ●
When backing up, hold the bottom of the
steering wheel with one hand. Move your
hand in the direction in which you want the
trailer to go. Make small corrections and
back up slowly. If possible, have someone
guide you when you are backing up.
Always block the wheels on both vehicle and
trailer when parking. Parking on a slope is not
recommended; however, if you must do so:CAUTION
If you move the shift selector to the P
(Park) position before blocking the
wheels and applying the parking brake,
transmission damage could occur.
1. Apply and hold the brake pedal.
2. Have someone place blocks on the downhill side of the vehicle and trailer wheels.
3. After the wheel blocks are in place, slowly release the brake pedal until the blocks ab-
sorb the vehicle load.
4. Apply the parking brake.
5. Shift the transmission into P (Park) .
6. Turn off the engine.
