2018 NISSAN ALTIMA service indicator

Overdrive (O/D) OFF mode switch
(if so equipped)
When the O/D OFF mode switch is pushed
with the shif t lever in the D (Drive) position,
the
light in the instrument panel illu-
minates. For additional information, refer
to “Overdrive OFF indicator light” in the “In-
struments and controls” section of this
manual.
Use the overdrive OFF mode when you
need improved engine braking. To turn off the overdrive OFF mode, push
the O/D OFF mode switch again. The
indicator light will turn off.
Each time the engine is started, or when
the shif t lever is shif ted to any position
other than D (Drive) and Ds (Drive Sport), the
overdrive OFF mode will automatically turn
off.
Accelerator downshif t
— in D (Drive) position —
For passing or hill climbing, depress the
accelerator pedal to the floor. This shif ts
the transmission down into a lower gear,
depending on the vehicle speed.
High fluid temperature protection
mode
This transmission has a high fluid tem-
perature protection mode. If the fluid tem-
perature becomes too high (for example,
when climbing steep grades in high tem-
peratures with heavy loads, such as when
towing a trailer), engine power and, under
some conditions, vehicle speed will be de-
creased automatically to reduce the
chance of transmission damage. Vehicle
speed can be controlled with the accelera-
tor pedal, but the engine and vehicle speed
may be limited.
Fail-safe
If the vehicle is driven under extreme
conditions, such as excessive wheel
spinning and subsequent hard braking,
the fail-safe system may be activated.
The Malfunction Indicator Light (MIL)
may come on to indicate the fail-safe
mode is activated. For additional infor-
mation, refer to “Malfunction Indicator
Light (MIL)” in the “Instruments and con-
trols” section of this manual. This will oc-
cur even if all electrical circuits are func-
tioning properly. In this case, place the
ignition switch in the OFF position and
wait for 10 seconds. Then push the
switch back to the ON position. The ve-
hicle should return to its normal operat-
ing condition. If it does not return to its
normal operating condition, have the
transmission checked. It is recom-
mended that you visit a NISSAN dealer
for this service.

Malfunction
When the RCTA system malfunctions, it will
turn off automatically. The system mal-
function warning message with the
BSW/RCTA indicator (orange) will appear in
the vehicle information display.
NOTE:
If the BSW system stops working, the
RCTA system (if so equipped) will also
stop working.
Action to take
Stop the vehicle in a safe location, place the
vehicle in the P (Park) position, turn the en-
gine off and restart the engine. If the mes-
sage continues to appear, have the system
checked. It is recommended that you visit a
NISSAN dealer for this service.
SYSTEM MAINTENANCE
The two radar sensors1for the BSW and
RCTA systems are located near the rear
bumper. Always keep the area near the ra-
dar sensors clean.
The radar sensors may be blocked by tem-
porary ambient conditions such as splash-
ing water, mist or fog.
The blocked condition may also be caused
by objects such as ice, frost or dirt ob-
structing the radar sensors.
Check for and remove objects obstructing
the area around the radar sensors. Do not attach stickers (including transpar-
ent material), install accessories or apply
additional paint near the radar sensors.
Do not strike or damage the area around
the radar sensors. It is recommended that
you visit a NISSAN dealer if the area around
the radar sensors is damaged due to a
collision.

Action to take
When the conditions listed above are no
longer present, turn the system off using
the ICC CRUISE
switch. Turn the ICC
system back on to use the system.
Condition B
When the radar sensor area of the front
bumper is covered with dirt or is ob-
structed, the ICC system will automatically
be canceled. If the sensor area is covered
with ice, a transparent or translucent vinyl
bag, etc., the ICC system may not detect
vehicles ahead. In these instances, the ICC
system may not cancel and may not be
able to maintain the selected following dis-
tance from the vehicle ahead. Be sure to
check and clean the sensor area.
The system warning light (orange) will illu-
minate and the “Unavailable: Front Radar
Obstruction” warning message will appear
in the vehicle information display.
When driving on roads with limited road
structures or buildings (for example, or
long bridges, deserts, snow field, driving
next to long walls), the system may illumi-
nate the system warning light (orange) and
display the “Unavailable: Front Radar Ob-
struction” message. Action to take
If the warning light (orange) comes on, park
the vehicle in a safe location and turn the
engine off. Check to see if the sensor area
of the front bumper is blocked. If the sensor
area of the front bumper is blocked, re-
move the blocking material. Restart the
engine. If the warning light continues to
illuminate, have the ICC system checked. It
is recommended that you visit a NISSAN
dealer for this service.
Condition C
When the ICC system is not operating
properly, a chime sounds and the system
warning light (orange) will come on.Action to take
If the warning light comes on, park the ve-
hicle in a safe place. Turn the engine off,
restart the engine, resume driving and set
the ICC system again.
If it is not possible to set the system or
the indicator stays on, it may indicate
that the system is malfunctioning. Al-
though the vehicle is still drivable under
normal conditions, have the vehicle
checked. It is recommended that you
visit a NISSAN dealer for this service.

5-56Starting and driving

If the brakes do not operate properly, have
the brakes checked. It is recommended
that you visit a NISSAN dealer for this ser-
vice.
Self-adjusting brakes
Your vehicle is equipped with self-adjusting
brakes.
The front and rear disc-type brakes self-
adjust every time the brake pedal is ap-
plied.
WARNING
Have your brake system checked if the
brake pedal height does not return to
normal. It is recommended that you
visit a NISSAN dealer for this service.
Brake pad wear indicators
The disc brake pads on your vehicle have
audible wear indicators. When a brake pad
requires replacement, a high pitched
scraping or screeching sound will be heard
when the vehicle is in motion. The noise will
be heard whether or not the brake pedal is
depressed. Have the brakes checked as
soon as possible if the wear indicator
sound is heard.Under some driving or climate conditions,
occasional brake squeak, squeal or other
noise may be heard. Occasional brake
noise during light to moderate stops is nor-
mal and does not affect the function or
performance of the brake system.
Proper brake inspection intervals should
be followed.
For additional information re-
garding brake inspections, refer to the ap-
propriate maintenance schedule informa-
tion in the "Maintenance and schedules"
section of this manual.
If any electrical equipment does not oper-
ate, check for an open fuse.
Fuses are used in the passenger and en-
gine compartment. Spare fuses are pro-
vided and can be found in the passenger
compartment fuse box.
When installing a fuse make sure the fuse is
installed in the fuse box securely.

Wheel nut tightening torque:83 f t-lb (113 N·m)
The wheel nuts must be kept tight-
ened to specifications at all times.
It is recommended that wheel nuts
be tightened to specification at
each tire rotation interval.
WARNING
∙ Af ter rotating the tires, check and adjust the tire pressure.
∙ Retighten the wheel nuts when the vehicle has been driven for
600 miles (1,000 km) (also in
cases of a flat tire, etc.).
∙ Do not include the spare tire in the tire rotation.
∙ For additional information re- garding tires, refer to “Impor-
tant Tire Safety Information”
(US) or “Tire Safety Information”
(Canada) in the Warranty Infor-
mation Booklet.
Tire wear and damage
1. Wear indicator
2. Location mark
WARNING
∙ Tires should be periodically in- spected for wear, cracking,
bulging or objects caught in the
tread. If excessive wear, cracks,
bulging or deep cuts are found,
the tire(s) should be replaced. ∙ The original tires have built-in
tread wear indicators. When the
wear indicators are visible, the
tire(s) should be replaced.
∙ Tires degrade with age and use. Have tires, including the spare,
over 6 years old checked by a
qualified technician because
some tire damage may not be
obvious. Replace the tires as
necessary to prevent tire failure
and possible personal injury.
∙ Improper service of the spare tire may result in serious per-
sonal injury. If it is necessary to
repair the spare tire, it is recom-
mended that you visit a NISSAN
dealer for this service.
∙ For additional information re- garding tires, refer to “Impor-
tant Tire Safety Information”
(US) or “Tire Safety Information”
(Canada) in the Warranty Infor-
mation Booklet.
