brake NISSAN ALTIMA 2012 Service Manual

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:

To drive away:1. Start the vehicle.
2. Apply and hold the brake pedal.
3. Shift the transmission into gear.
4. Release the parking brake.
5. Drive slowly until the vehicle and trailer are clear from the blocks.
6. Apply and hold the brake pedal.
7. Have someone retrieve and store the blocks. ● While going downhill, the weight of the
trailer pushing on the tow vehicle may dete-
riorate overall handling characteristics.
Therefore, to maintain adequate control, re-
duce your speed and shift to a lower gear.
Avoid long or repeated use of the brakes
when descending a hill, as this reduces their
effectiveness and could cause overheating.
Shifting to a lower gear instead provides
“engine braking” and reduces the need to
brake as frequently.
● If the engine coolant temperature rises to a
high temperature, refer to “If your vehicle
overheats” in the “In case of emergency”
section of this owner’s manual.
● Trailer towing requires more fuel than normal
circumstances. ●
Avoid towing a trailer for your vehicle’s first
500 miles (805 km) .
● For the first 500 miles (805 km) that you do
tow, do not drive over 50 MPH (80 km/h) .
● Have your vehicle serviced more often than
at intervals specified in the recommended
Maintenance Schedule in the “NISSAN Ser-
vice and Maintenance Guide”.
● When making a turn, your trailer wheels will
be closer to the inside of the turn than your
vehicle wheels. To compensate for this,
make a larger than normal turning radius
during the turn.
● Crosswinds and rough roads will adversely
affect vehicle/trailer handling, possibly caus-
ing vehicle sway. When being passed by
larger vehicles, be prepared for possible
changes in crosswinds that could affect ve-
hicle handling.
Do the following if the trailer begins to sway: 1. Take your foot off the accelerator pedal to allow the vehicle to coast and steer as
straight ahead as the road conditions allow.
This combination will help stabilize the ve-
hicle
– Do not correct trailer sway by steering or applying the brakes. 2. When the trailer sway stops, gently apply the
brakes and pull to the side of the road in a
safe area.
3. Try to rearrange the trailer load so it is bal- anced as described earlier in this section.
● Be careful when passing other vehicles.
Passing while towing a trailer requires con-
siderably more distance than normal pass-
ing. Remember, the length of the trailer must
also pass the other vehicle before you can
safely change lanes.
● Use the Tow Mode or downshift the trans-
mission to a lower gear for engine braking
when driving down steep or long hills. This
will help slow the vehicle without applying
the brakes.
● Avoid holding the brake pedal down too long
or too frequently. This could cause the
brakes to overheat, resulting in reduced
braking efficiency.
● Increase your following distance to allow for
greater stopping distances while towing a
trailer. Anticipate stops and brake gradually.
● NISSAN recommends that the cruise con-
trol not be used while towing a trailer.

Additional information concerning motor
vehicle safety may be obtained from
Transport Canada’s Road Safety Informa-
tion Centre at 1-800-333-0371 or online
at www.tc.gc.ca/roadsafety (English
speakers) or

speakers) .
To notify NISSAN of any safety concerns
please contact our Consumer Information
Centre toll free at 1-800-387-0122.Due to legal requirements in some states and
Canadian Provinces, your vehicle may be re-
quired to be in what is called the “ready condi-
tion” for an Inspection/Maintenance (I/M) test of
the emission control system.
The vehicle is set to the “ready condition” when it
is driven through certain driving patterns. Usually,
the ready condition can be obtained by ordinary
usage of the vehicle.
If a powertrain system component is repaired or
the battery is disconnected, the vehicle may be
reset to a “not ready” condition. Before taking the
I/M test, check the vehicle’s
inspection/maintenance test readiness condi-
tion. Place the ignition switch in the ON position
without starting the engine. If the Malfunction
Indicator Light (MIL) comes on steady for 20
seconds and then blinks for 10 seconds , the I/M
test condition is “not ready”. If the MIL does not
blink after 20 seconds, the I/M test condition is
“ready”. Contact a NISSAN dealer to set the
“ready condition” or to prepare the vehicle for
testing.This vehicle is equipped with an Event Data Re-
corder (EDR) . The main purpose of an EDR is to
record, in certain crash or near crash-like situa-
tions, such as an air bag deployment or hitting a
road obstacle, data that will assist in understand-
ing how a vehicle’s systems performed. The EDR
is designed to record data related to vehicle
dynamics and safety systems for a short period of
time, typically 30 seconds or less. The EDR in this
vehicle is designed to record such data as:
● How various systems in your vehicle were
operating;
● Whether or not the driver and passenger
safety belts were buckled/fastened;
● How far (if at all) the driver was depressing
the accelerator and/or brake pedal; and,
● How fast the vehicle was traveling.
● Sounds are not recorded.
These data can help provide a better understand-
ing of the circumstances in which crashes and
injuries occur. NOTE: EDR data are recorded by
your vehicle only if a nontrivial crash situation
occurs; no data are recorded by the EDR under
normal driving conditions and no personal data
(e.g. name, gender, age and crash location) are
recorded. However, other parties, such as law
enforcement, could combine the EDR data with
