2018 NISSAN ALTIMA SL belt

When pretensioner(s) activate, smoke is re-
leased and a loud noise may be heard. This
smoke is not harmful and does not indi-
cate a fire. Care should be taken not to
inhale it, as it may cause irritation and
choking. Those with a history of a breath-
ing condition should get fresh air promptly.
Af ter the pretensioner(s’) activation, load
limiters allow the seat belt to release web-
bing (if necessary) to reduce forces against
the chest.
The supplemental air bag warning
light

∙ If there is an impact to your vehiclefrom any direction, your Occupant
Classification Sensor (OCS) should be
checked to verif y it is still functioning
correctly. It is recommended that you
visit a NISSAN dealer for this service.
The OCS should be checked even if
no air bags deploy as a result of the
impact. Failure to verif y proper OCS
function may result in an improper air
bag deployment resulting in injury or
death.
1-68Safety—Seats, seat belts and supplemental restraint system

Supplemental air bagwarning light
When the ignition switch is placed in the ON
or START position, the supplemental air
bag warning light illuminates for about
7 seconds and then turns off. This means
the system is operational.
If any of the following conditions occur, the
front air bag, side air bag, curtain air bag,
and pretensioner systems need servicing
and your vehicle must be taken to a NISSAN
dealer:
∙ The supplemental air bag warning light remains on af ter approximately 7 sec-
onds.
∙ The supplemental air bag warning light flashes intermittently.
∙ The supplemental air bag warning light does not come on at all.
Unless checked and repaired, the supple-
mental restraint system (air bag system)
and/or the pretensioners may not function
properly. For additional details, refer to
“Supplemental Restraint System (SRS)” in
the “Safety—Seats, seat belts and supple-
mental restraint system” section of this
manual.

∙ Do not grip the inside or spokes of thesteering wheel when driving off-road.
The steering wheel could move sud-
denly and injure your hands. Instead
drive with your fingers and thumbs on
the outside of the rim.
∙ Before operating the vehicle, ensure that the driver and all passengers
have their seat belts fastened.
∙ Always drive with the floor mats in place as the floor may become hot.
∙ Lower your speed when encountering strong crosswinds. With a higher cen-
ter of gravity, your NISSAN is more af-
fected by strong side winds. Slower
speeds ensure better vehicle control.
∙ Do not drive beyond the performance capability of the tires, even with AWD
engaged.
∙ For AWD equipped vehicles, do not at- tempt to raise two wheels off the
ground and shif t the transmission to
any drive or reverse position with the
engine running. Doing so may result
in drivetrain damage or unexpected
vehicle movement which could result
in serious vehicle damage or personal
injury. ∙ Do not attempt to test an AWD
equipped vehicle on a 2-wheel dyna-
mometer (such as the dynamometers
used by some states for emissions
testing) or similar equipment even if
the other two wheels are raised off the
ground. Make sure you inform test fa-
cility personnel that your vehicle is
equipped with AWD before it is placed
on a dynamometer. Using the wrong
test equipment may result in drive-
train damage or unexpected vehicle
movement which could result in seri-
ous vehicle damage or personal
injury.
∙ When a wheel is off the ground due to an unlevel surface, do not spin the
wheel excessively.
∙ Accelerating quickly, sharp steering maneuvers or sudden braking may
cause loss of control.
∙ If at all possible, avoid sharp turning maneuvers, particularly at high
speeds. Your NISSAN vehicle has a
higher center of gravity than a pas-
senger car. The vehicle is not de-
signed for cornering at the same
speeds as passenger cars. ∙ Failure to operate this vehicle cor-
rectly could result in loss of control
and/or a rollover accident.
∙ Always use tires of the same type, size, brand, construction (bias, bias-
belted, or radial), and tread pattern on
all four wheels. Install tire chains on
the front wheels when driving on slip-
pery roads and drive carefully.
∙ Be sure to check the brakes immedi- ately af ter driving in mud or water. For
additional information, refer to “Brake
precautions” in this section.
∙ Avoid parking your vehicle on steep hills. If you get out of the vehicle and it
rolls forward, backward or sideways,
you could be injured.
∙ Whenever you drive off-road through sand, mud or water as deep as the
wheel hub, more frequent mainte-
nance may be required. For additional
information, refer to “Maintenance
under severe operating conditions” in
the “Maintenance and schedules” sec-
tion of this manual.
5-12Starting and driving

PEDAL TYPE
To engage:Firmly depress the parking
brake.
To release:
1. Firmly apply the foot brake.
2. Move the shif t lever to the P (Park) po- sition.
3. Firmly depress the parking brake pedal and it will release.
4. Before driving, be sure the brake warn- ing light goes out.
SWITCH TYPE (models with
electronic parking brake system)
The electronic parking brake can be ap-
plied or released automatically or by oper-
ating the parking brake switch.
Automatic operation
The electronic parking brake will apply au-
tomatically if the ignition switch is placed in
the OFF position when the brake force is
maintained by the automatic brake hold
function. The electronic parking brake is automati-
cally released as soon as the vehicle starts
and the accelerator pedal is depressed
with the driver’s seat belt fastened.

∙ The automatic brake hold functionwill not be activated if the Vehicle Dy-
namic Control (VDC) OFF indicator
light, electronic parking brake warn-
ing light or master warning light illu-
minate and the chassis control sys-
tem fault message appears in the
vehicle information display.
∙ To maintain the braking force to keep the vehicle to a standstill, a noise may
be heard. This is not a malfunction.
HOW TO ACTIVATE/DEACTIVATE
THE AUTOMATIC BRAKE HOLD
FUNCTION
For additional information on activating
and deactivating the automatic brake hold
function, refer to the instructions outlined
in this section.
How to activate the automatic
brake hold function
1. With the ignition switch in the ON posi- tion, push the automatic brake hold
switch
1. The indicator light on the au-
tomatic brake hold switch
2illumi-
nates.

nates.
To use the automatic brake hold function,
the following conditions need to be met: ∙ The driver’s seat belt is fastened.
∙ The electronic parking brake is re- leased.
∙ The shif t lever is not in the P (Park) posi- tion.
∙ The vehicle is not parked on a steep hill.
NOTE:
The automatic brake hold function re-
sets to OFF every time the ignition
switch is switched from the OFF position
to the ON position.

The illustration shows the location of the
floor mat positioning aids.
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 com-
pletely in the shade before using them. For
additional information, refer to “Seat belt
maintenance” in the “Safety—Seats, seat
belts and supplemental restraint system”
section of this manual.

1. Visually inspect the belt for signs of un-usual wear, cuts, or fraying. If the belt is
in poor condition, have it replaced. It is
recommended that you visit a NISSAN
dealer for this service.
2. Have the belt checked regularly for condition.
REPLACING SPARK PLUGS
Iridium-tipped spark plugs
It is not necessary to replace iridium-
tipped
Aspark plugs as frequently as con-
ventional type spark plugs because they
last much longer. Follow the maintenance
log shown in the “Maintenance and sched-
ules” section of this manual. Do not service
iridium-tipped spark plugs by cleaning or
regapping.
∙ Always replace spark plugs with rec-
ommended or equivalent ones.
