2010 NISSAN ALTIMA COUPE ECU

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.
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.

8-42Maintenance and do-it-yourself

Steps for determining correct load
limit
1. Locate the statement “The combinedweight of occupants and cargo
should never exceed XXX kg or XXX
lbs” on your vehicle’s placard.
2. Determine the combined weight of the driver and passengers that will be
riding in your vehicle.
3. Subtract the combined weight of the driver and passengers from XXX kg
or XXX lbs.
4. The resulting figure equals the avail- able amount of cargo and luggage
load capacity. For example, if the
XXX amount equals 1400 lbs. and
there will be five 150 lb. passengers
in your vehicle, the amount of avail-
able cargo and luggage load capac-
ity is 650 lbs. (1400-750 (5 X 150)
= 650 lbs) or (640-340 (5 X 70) =
300 kg.) 5. Determine the combined weight of
luggage and cargo being loaded on
the vehicle. That weight may not
safely exceed the available cargo and
luggage load capacity calculated in
Step 4.
6. If your vehicle will be towing a trailer, load from your trailer will be trans-
ferred to your vehicle. Consult this
manual to determine how this re-
duces the available cargo and lug-
gage load capacity of your vehicle.
Before driving a loaded vehicle, confirm
that you do not exceed the Gross Vehicle
Weight Rating (GVWR) or the Gross Axle
Weight Rating (GAWR) for your vehicle.
See “Measurement of Weights” later in
this section.
Also check tires for proper inflation pres-
sures. See the Tire and Loading Informa-
tion label.
LOADING TIPS
● The GVW must not exceed GVWR
or GAWR as specified on the
F.M.V.S.S./C.M.V.S.S. certification
label.
● Do not load the front and rear axle to
the GAWR. Doing so will exceed the
GVWR.
WARNING
● Properly secure all cargo with
ropes or straps to help prevent it
from sliding or shifting. Do not
place cargo higher than the seat-
backs. In a sudden stop or colli-
sion, unsecured cargo could
cause personal injury.
● Do not load your vehicle any
heavier than the GVWR or the
maximum front and rear GAWRs.
If you do, parts of your vehicle
can break, tire damage could oc-
cur, or it can change the way your
vehicle handles. This could result
in loss of control and cause per-
sonal injury.
Technical and consumer information9-15

●Overloading not only can shorten
the life of your vehicle and the
tire, but can also cause unsafe
vehicle handling and longer brak-
ing distances. This may cause a
premature tire failure which
could result in a serious accident
and personal injury. Failures
caused by overloading are not
covered by the vehicle’s
warranty.
MEASUREMENT OF WEIGHTS
Secure loose items to prevent weight
shifts that could affect the balance of your
vehicle. When the vehicle is loaded, drive
to a scale and weigh the front and the rear
wheels separately to determine axle
loads. Individual axle loads should not ex-
ceed either of the gross axle weight rat-
ings (GAWR) . The total of the axle loads
should not exceed the gross vehicle
weight rating (GVWR) . These ratings are
given on the vehicle certification label. If
weight ratings are exceeded, move or re-
move items to bring all weights below the
ratings.
WARNING
Overloading or improper loading of a
trailer and its cargo can adversely affect
vehicle handling, braking and perfor-
mance and may lead to accidents.
CAUTION
● Do not tow a trailer or haul a heavy load
for the first 500 miles (800 km) . Your
engine, axle or other parts could be
damaged.
● For the first 500 miles (800 km) that you
tow a trailer, do not drive over 50 mph
(80 km/h) and do not make starts at full
throttle. This helps the engine and other
parts of your vehicle wear in at the
heavier loads.
Your new vehicle was designed to be used pri-
marily to carry passengers and cargo. Remember
that towing a trailer places additional loads on
your vehicle’s engine, drive train, steering, brak-
ing and other systems.
A NISSAN Towing Guide (U.S. only) is available
on the website at www.nissanusa.com. This
guide includes information on trailer towing ca-
pability and the special equipment required for
proper towing.
MAXIMUM LOAD LIMITS
Maximum trailer loads
Never allow the total trailer load to exceed the
value specified in the “Towing
Load/Specification” chart found later in this sec-
tion. The total trailer load equals trailer weight
plus its cargo weight. ● When towing a trailer load of 1,000 lbs.
(454 kg) or more, trailers with a brake
system must be used.
TOWING A TRAILER
9-16Technical and consumer information

4,203 lb. (1906 kg) GVWR
– 4,103 lb. (1861 kg) GVW
= 100 lb. (45 kg) Available for tongue weight
1,000 lb. (454 kg) Capacity available for towing
100 lb. (45 kg) Available tongue weight
/ 1,000 lb. (454 kg) Available capacity
= 10 % tongue weight
The available towing capacity may be less than
the maximum towing capacity due to the passen-
ger and cargo load in the vehicle.
Remember to keep trailer tongue weight be-
tween 10 - 15% of the trailer weight or within the
trailer tongue load specification recommended
by the trailer manufacturer. If the tongue load
becomes excessive, rearrange the cargo to ob-
tain the proper tongue load. Do not exceed the
maximum tongue weight specification shown in
the “Towing load/specification” chart even if the
calculated available tongue weight is greater
than 15%. If the calculated tongue weight is less
than 10% , reduce the total trailer weight to
match the available tongue weight. Always verify that available capacities are within
the required ratings.

TOWING SAFETY
Trailer hitch
Choose a proper hitch for your vehicle and trailer.
Make sure the trailer hitch is securely attached to
the vehicle, to help avoid personal injury or prop-
erty damage due to sway caused by crosswinds,
rough road surfaces or passing trucks.
WARNING
Trailer hitch components have specific
weight ratings. Your vehicle may be ca-
pable of towing a trailer heavier than the
weight rating of the hitch components.
Never exceed the weight rating of the
hitch components. Doing so can cause
serious personal injury or property
damage.
Hitch ball
Choose a hitch ball of the proper size and weight
rating for your trailer:
● The required hitch ball size is stamped on
most trailer couplers. Most hitch balls also
have the size printed on the top of the ball.
● Choose the proper class hitch ball based on
the trailer weight.
● The diameter of the threaded shank of the
hitch ball must be matched to the ball mount
hole diameter. The hitch ball shank should
be no more than 1/16” smaller than the hole
in the ball mount.
Technical and consumer information9-19

●The threaded shank of the hitch ball must be
long enough to be properly secured to the
ball mount. There should be at least 2
threads showing beyond the lock washer
and nut.
Ball mount
The hitch ball is attached to the ball mount and
the ball mount is inserted into the hitch receiver.
Choose a proper class ball mount based on the
trailer weight. Additionally, the ball mount should
be chosen to keep the trailer tongue level with the
ground.
Sway control device
Sudden maneuvers, wind gusts, and buffeting
caused by other vehicles can affect trailer han-
dling. Sway control devices may be used to help
control these affects. If you choose to use one,
contact a reputable trailer hitch supplier to make
sure the sway control device will work with the
vehicle, hitch, trailer and the trailer’s brake sys-
tem. Follow the instructions provided by the
manufacturer for installing and using the sway
control device.
Class I hitch
Class I trailer hitch equipment (receiver, ball
mount and hitch ball) can be used to tow trailers
of a maximum weight of 2,000 lb (909 kg) . You may add Class I trailer hitch equipment that
has a 2,000 lb (909 kg) maximum weight rating to
the vehicle, but your vehicle is only capable of
towing the maximum trailer weights shown in the
Towing Load/Specification chart earlier in this
section.
CAUTION
●
Do not use axle-mounted hitches.
● The hitch should not be attached to or
affect the operation of the impact-
absorbing bumper.
● Do not modify the vehicle exhaust sys-
tem, brake system, etc. to install a
trailer hitch.
● To reduce the possibility of additional
damage if your vehicle is struck from
the rear, where practical, remove the
receiver when not in use.
● After the hitch is removed, seal the bolt
holes to prevent exhaust fumes, water
or dust from entering the passenger
compartment.
● Regularly check that all trailer hitch
mounting bolts are securely mounted.
Tire pressures
● When towing a trailer, inflate the ve-
hicle tires to the recommended cold
tire pressure indicated on the Tire
and Loading Information label.
● Trailer tire condition, size, load rating
and proper inflation pressure should
be in accordance with the trailer and
tire manufacturer’s specifications.
Safety chains
Always use suitable safety chains between your
vehicle and the trailer. The safety chains should
be crossed and should be attached to the hitch,
not to the vehicle bumper or axle. Be sure to leave
enough slack in the chains to permit turning
corners.
9-20Technical and consumer information

Trailer lights
CAUTION
When splicing into the vehicle electrical
system, a commercially available power-
type module/converter must be used to
provide power for all trailer lighting. This
unit uses the vehicle battery as a direct
power source for all trailer lights while
using the vehicle tail light, stoplight and
turn signal circuits as a signal source. The
module/converter must draw no more
that 15 milliamps from the stop and tail
lamp circuits. Using a module/converter
that exceeds these power requirements
may damage the vehicle’s electrical sys-
tem. See a reputable trailer dealer to ob-
tain the proper equipment and to have it
installed.
Trailer lights should comply with federal and/or
local regulations. For assistance in hooking up
trailer lights, contact a NISSAN dealer or repu-
table trailer dealer.
Trailer brakes
If your trailer is equipped with a braking system,
make sure it conforms to federal and/or local
regulations and that it is properly installed.
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 inadvert-
ently becoming unlatched.
● Avoid abrupt starts, acceleration or stops.
● Avoid sharp turns or lane changes.
● Always drive your vehicle at a moderate
speed.
