Door and trunk open warning
This warning illuminates when a door or the trunk
has been opened when the engine is running.
Push warning (CVT models)
After the Shift P warning illuminates, the Push

This warning illuminates when the parking brake
is set and the vehicle is driven.
SHIFT P warning (CVT models)
This warning illuminates when the ignition switch
is pushed to stop the engine with the shift selec-
tor in any position except in the P (Park) position.
If this warning illuminates, the ignition switch is
placed in the OFF position. Move the shift selec-
tor to the P (Park) position or place the ignition
switch in the ON position.
An inside warning chime will also sound.
If the shift selector is moved to the P (Park)
position, the Push warning will appear. Refer to
“Push warning (CVT models)” in this section.

direction. See “Push-button ignition switch” in
the “Starting and driving” section.NISSAN Intelligent Key™ removal indica-
tor
This indicator illuminates when the driver’s door
is opened with the ignition switch placed in the
OFF position and the Intelligent Key placed in the
Intelligent Key port. A key reminder chime also

you when leaving the vehicle.
NISSAN Intelligent Key™ battery dis-
charge indicator
This indicator illuminates when the Intelligent Key

If this indicator illuminates, replace the battery
with a new one. See “NISSAN Intelligent Key™” in
the “Maintenance and do-it-yourself” section.
Loose fuel cap warning
This warning appears when the fuel-filler cap is
not tightened correctly after the vehicle has been
refueled. See “Fuel-filler cap” in the “Pre-driving
checks and adjustments” section.
Check tire pressure warning
This warning appears when the low tire pressure
warning light in the meter illuminates and low tire
pressure is detected. If this warning appears,
stop the vehicle and adjust the tire pressure to
the recommended COLD tire pressure shown on
the Tire and Loading Information label. See “Low
tire pressure warning light” earlier in this section
and “Tire Pressure Monitoring System (TPMS)”
in the “Starting and driving” section.

CAUTION
During the first 1,200 miles (2,000 km) ,
follow these recommendations to obtain
maximum engine performance and en-
sure the future reliability and economy of
your new vehicle. Failure to follow these
recommendations may result in short-
ened engine life and reduced engine
performance.● Avoid driving for long periods at constant
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 possible.
● Do not tow a trailer for the first 500 miles
(800 km) . Your engine, axle or other parts
could be damaged. ●
Accelerate slowly and smoothly. Maintain
cruising speeds with a constant accelerator
position.
● Drive at moderate speeds on the highway.
Driving at high speed lowers fuel economy.
● Avoid unnecessary stopping and braking.
Maintain a safe distance behind other ve-
hicles.
● Use a proper gear range which suits road
conditions. On level roads, shift into high
gear as soon as possible.
● Avoid unnecessary engine idling.
● Keep your engine tuned up.
● Follow the recommended periodic mainte-
nance schedule.
● Keep the tires inflated to the correct pres-
sure. Low tire pressure increases tire wear
and lowers fuel economy.
● Keep the wheels in correct alignment. Im-
proper alignment increases tire wear and
lowers fuel economy.
● Air conditioner operation lowers fuel
economy. Use the air conditioner only when
necessary. ●
When cruising at highway speeds, it is more
economical to use the air conditioner and
leave the windows closed to reduce drag.
● Use the recommended viscosity engine oil.
See “Capacities and recommended
fuel/lubricants” in the “Technical and con-
sumer information” section of this manual.
