2019 NISSAN ALTIMA SL engine

TACHOMETER
The tachometer indicates engine speed in
revolutions per minute (rpm). Do not rev
the engine into the red zone
1.

VARIABLE COMPRESSION TURBO
(if so equipped)
Your engine is equipped with a variable
compression ratio system called “Variable
Compression Turbo”. This system can vary
the engine compression ratio continu-
ously.
According to driving conditions, the system
applies optimum compression ratio auto-
matically to achieve both high output and
high fuel economy efficiency.This is not a physical gauge. It is a display
option in the vehicle information display
that can be selected. For additional infor-
mation, refer to “Vehicle information dis-
play” in this section.
1Compression ratio status display
Displays the status of compression ra-
tio controlled by Variable Compression
Turbo. The lowest compression ratio
(8:1) and the highest (14:1) are displayed
as “Power” and ”Eco” respectively.
2Turbo charger boost pressure gauge
Displays the turbo charger boost pres-
sure.
NOTE:
Under some conditions, the compres-
sion ratio may not change. This is not a
malfunction of the system.

CAUTION
Use the headlights with the engine run-
ning to avoid discharging the vehicle
battery.
Autolight system (if so equipped)
The autolight system allows the headlights
to turn on and off automatically. The auto-
light system can:∙ Turn on the headlights, front parking, tail, license plate and instrument panel
lights automatically when it is dark.
∙ Turn off all the lights when it is light.
∙ Keep all the lights on for a period of time af ter you place the ignition switch in the
OFF position and all doors are closed. NOTE:
Autolight activation sensitivity and the
time delay for autolight shutoff can be
adjusted. For additional information, re-
fer to “Vehicle information display ” in
this section.
To turn on the autolight system:
1. Turn the headlight switch to the AUTO position
1.
2. Turn the ignition switch to ON.
3. The autolight system automatically turns the headlights on and off.
Initially, if the ignition switch is placed in the
OFF position and a door is opened and lef t
open, the headlights remain on for a period
of time. If another door is opened while the
headlights are on, then the timer is reset.
To turn the autolight system off, turn the
switch to the OFF,

Be sure you do not put anything on top
of the autolight sensor located in the top
side
1of the instrument panel. The au-
tolight sensor controls the autolight; if it
is covered, the autolight sensor reacts as
if it is dark out and the headlights will
illuminate. If this occurs while parked
with the engine off and the ignition
switch placed in the ON position, your
vehicle’s battery could become dis-
charged.

DAYTIME RUNNING LIGHTS (DRL)
SYSTEM (Type A) (if so equipped)
The Daytime Running Lights (DRL) automati-
cally illuminate when the engine is started
with the parking brake released. The DRL
operate with the headlight switch in the
OFF position. Turn the headlight switch to

∙ Only certain power outlets are de-signed for use with a cigarette lighter
unit. Do not use any other power out-
let for an accessory lighter. For addi-
tional information, it is recommended
that you visit a NISSAN dealer.
∙ Do not use with accessories that ex- ceed a 12 volt, 120W (10A) power draw.
∙ Do not use double adapters or more than one electrical accessory.
∙ Use power outlets with the engine running to avoid discharging the ve-
hicle battery.
∙ Avoid using power outlets when the air conditioner, headlights, or rear
window defroster is on.
∙ Before inserting or disconnecting a plug, be sure the electrical accessory
being used is turned OFF.
∙ Push the plug in as far as it will go. If good contact is not made, the plug
may overheat or the internal tem-
perature fuse may open.
∙ When not in use, be sure to close the cap. Do not allow water or any other
liquid to contact the outlet.

∙ When the climate system is in auto-matic operation and the engine coolant
temperature and outside air tempera-
ture are low, the air flow outlet may de-
fault to defroster mode for a maximum
of 2 minutes 30 seconds. This is not a
malfunction. Af ter the engine coolant
temperature warms up, the air flow out-
let will return to foot mode and opera-
tion will continue normally.
∙ When the outside and interior cabin temperatures are moderate to high, the
intake setting may default to turn off air
recirculation to allow fresh air into the
passenger compartment. You may no-
tice air flow from the foot mode, bi-level
mode, or side demist vent outlets for a
maximum of 15 seconds. This may oc-
cur when the previous climate setting
was turned off. This is not a malfunction.
Af ter the initial warm air is expelled, the
intake will return to automatic control,
the air flow outlet will return to previous
settings, and operation will continue
normally. To exit, press any climate con-
trol button. ∙ Keep the moonroof (if so equipped)
closed while the air conditioner is in op-
eration.
∙ If you feel that the air flow mode you have selected and the outlets the air is
coming out do not match, select
the

∙ 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.
