2018 NISSAN ALTIMA SL fuel

FUEL GAUGE
The gauge indicates theapproximatefuel
level in the tank.
The gauge may move slightly during brak-
ing, turning, acceleration, or going up or
down hills.
The gauge needle returns to 0 (Empty) af-
ter the ignition switch is placed in the OFF
position.
The low fuel warning message shows in
the vehicle information display when the
amount of fuel in the tank is getting low. Refill the fuel tank before the gauge reg-
isters 0 (Empty).
The

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.

Master warning light
When the ignition is in the ON position, the
master warning light illuminates if any of
the following are displayed on the vehicle
information display.∙ No key warning
∙ Low windshield-washer fluid warning
∙ Parking brake release warning
∙ Door/trunk open warning
∙ Loose fuel cap
∙ Low tire pressure warning

Operation
The MIL will come on in one of two ways:∙ MIL on steady — An emission control system malfunction has been de-
tected. Check the fuel-filler cap if the
Loose Fuel Cap warning appears in the
vehicle information display. If the fuel-
filler cap is loose or missing, tighten or
install the cap and continue to drive the
vehicle. The

WARNING
∙ Never allow anyone to ride in thecargo area or on the rear seat when it
is in the fold-down position. Use of
these areas by passengers without
proper restraints could result in seri-
ous injury or death in an accident or
sudden stop.
∙ Properly secure all cargo with ropes or straps to help prevent it from sliding
or shif ting. Do not place cargo higher
than the seatbacks. In a sudden stop
or collision, unsecured cargo could
cause personal injury.
∙ When returning the seatbacks to the upright position, be certain they are
completely secured in the latched po-
sition. If they are not completely se-
cured, passengers may be injured in
an accident or sudden stop.
∙ Closely supervise children when they are around cars to prevent them from
playing and becoming locked in the
trunk where they could be seriously
injured. Keep the car locked, with the
rear seatback and trunk lid securely
latched when not in use, and prevent
children’s access to car keys.
OPENER OPERATION
The fuel-filler door release is located below
the instrument panel. To open the fuel-filler
door, pull the release. To lock, close the fuel-
filler door securely.
FUEL-FILLER CAP

∙ Do not fill a portable fuel container inthe vehicle or trailer. Static electricity
can cause an explosion of flammable
liquid, vapor or gas in any vehicle or
trailer. To reduce the risk of serious
injury or death when filling portable
fuel containers:
– Always place the container on the ground when filling.
– Do not use electronic devices when filling.
– Keep the pump nozzle in contact with the container while you are
filling it.
– Use only approved portable fuel containers for flammable liquid.

To remove the fuel-filler cap:1. Turn the fuel-filler cap counterclock- wise to remove.
2. Put the fuel-filler cap on the cap holder
1while refueling.
To install the fuel-filler cap: 1. Insert the fuel-filler cap straight into the fuel-filler tube.
2. Turn the fuel-filler cap clockwise until a single click is heard.
Loose Fuel Cap warning
The Loose Fuel Cap warningAappears in
the vehicle information display when the
fuel-filler cap is not tightened correctly af-
ter the vehicle has been refueled. It may
take a few driving trips for the message to
be displayed. To turn off the warning, per-
form the following:
1. Remove and install the fuel-filler cap as soon as possible. For additional infor-
mation, refer to “Fuel-filler cap” in this
section.
2. Tighten the fuel-filler cap until it clicks.

CAUTION
During the first 1,200 miles (2,000 km),
follow these recommendations to ob-
tain maximum engine performance
and ensure the future reliability and
economy of your new vehicle. Failure to
follow these recommendations may re-
sult in shortened engine life and re-
duced engine performance.∙ Avoid driving for long periods at con- stant speed, either fast or slow, and do
not run the engine over 4,000 rpm.
∙ Do not accelerate at full throttle in any gear.
∙ Avoid quick starts.
∙ Avoid hard braking as much as pos- sible. Follow these easy-to-use Fuel Efficient
Driving Tips to help you achieve the most
fuel economy from your vehicle.
1. Use Smooth Accelerator and Brake
Pedal Application
∙ Avoid rapid starts and stops.
∙ Use smooth, gentle accelerator and brake application whenever possible.
∙ Maintain constant speed while com- muting and coast whenever pos-
sible.
2. Maintain Constant Speed
∙ Look ahead to try and anticipate and minimize stops.
∙ Synchronizing your speed with traffic lights allows you to reduce your num-
ber of stops.
∙ Maintaining a steady speed can mini- mize red light stops and improve fuel
efficiency.
3. Use Air Conditioning (A/C) at Higher
Vehicle Speeds
∙ Below 40 mph (64 km/h), it is more efficient to open windows to cool the
vehicle due to reduced engine load. ∙ Above 40 mph (64 km/h), it is more
efficient to use A/C to cool the vehicle
due to increased aerodynamic drag.
∙ Recirculating the cool air in the cabin when the A/C is on reduces cooling
load.
4. Drive at Economical Speeds and
Distances
∙ Observing the speed limit and not exceeding 60 mph (97 km/h) (where
legally allowed) can improve fuel effi-
ciency due to reduced aerodynamic
drag.
∙ Maintaining a safe following distance behind other vehicles reduces un-
necessary braking.
∙ Safely monitoring traffic to anticipate changes in speed permits reduced
braking and smooth acceleration
changes.
∙ Select a gear range suitable to road conditions.
