∙ Do not leave children or adults who would normally require the assis-
tance of others alone in your vehicle.
Pets should also not be lef t alone.
They could accidentally injure them-
selves or others through inadvertent
operation of the vehicle. Also, on hot,
sunny days, temperatures in a closed
vehicle could quickly become high
enough to cause severe or possibly
fatal injuries to people or animals.
∙ Do not use the recirculation mode for long periods as it may cause the inte-
rior air to become stale and the win-
dows to fog up.

Operating tips
∙ Keep the windows and moonroof (if soequipped) closed while the air condi-
tioner is in operation.
∙ Af ter parking in the sun, drive for two or three minutes with the windows open
to vent hot air from the passenger
compartment. Then, close the win-
dows. This allows the air conditioner to
cool the interior more quickly. ∙
The air conditioning system should
be operated for approximately
10 minutes at least once a month.
This helps prevent damage to the
system due to lack of lubrication.
∙ A visible mist may be seen coming from the ventilators in hot, humid conditions
as the air is cooled rapidly. This does not
indicate a malfunction.
∙ If the engine coolant temperature
gauge indicates engine coolant tem-
perature over the normal range, turn

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.
∙ Do not tow a trailer for the first 500 miles (805 kilometers). Your engine, axle or
other parts could be damaged. 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 Dis-
tances
∙ 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.
BREAK-IN SCHEDULE FUEL EFFICIENT DRIVING TIPS
5-24Starting and driving

∙ The system is designed as an aid tothe driver in detecting large station-
ary objects to help avoid damaging
the vehicle. The system will not detect
small objects below the bumper, and
may not detect objects close to the
bumper or on the ground.
∙ If your vehicle sustains damage to the rear bumper fascia, leaving it mis-
aligned or bent, the sensing zone may
be altered causing inaccurate mea-
surement of obstacles or false alarms.
The RSS sounds a tone to warn the driver of
obstacles near the rear bumper when the
shif t lever is in R (Reverse). The system may
not detect objects at speeds above 3 mph
(5 km/h) and may not detect certain angu-
lar or moving objects.
The RSS detects obstacles up to 5.9 f t
(1.8 m) from the rear bumper with a de-
creased coverage area at the outer cor-
ners of the bumper (refer to the illustration
for approximate zone coverage areas). As
you move closer to the obstacle, the rate of
the tone increases. When the obstacle is
less than 10 in (25.0 cm) away, the tone will
sound continuously. If the RSS detects a
stationary or receding object further than
10 in (25.0 cm) from the side of the vehicle, the tone will sound for only 3 seconds.
Once the system detects an object ap-
proaching, the tone will sound again.
The RSS automatically turns on when the
shif t lever is placed in R (Reverse) and the
ignition is ON. The RSS OFF switch on the
instrument panel allows the driver to turn
the RSS on and off. To turn the RSS off, the
ignition must be on, and the shif t lever in R
(Reverse). An indicator light on the switch
will illuminate when the system is turned
off. If the indicator light illuminates when
the RSS is not turned off, it may indicate a
malfunction in the RSS.
Keep the RSS sensors (located on the rear
bumper fascia) free from snow, ice and
large accumulations of dirt (do not clean
the sensors with sharp objects). If the sen-
sors are covered, it will affect the accuracy
of the RSS.FREEING A FROZEN DOOR LOCK
To prevent a door lock from freezing, apply
de-icer through the key hole. If the lock
becomes frozen, heat the key before in-
serting it into the key hole or use the re-
mote keyless entry key fob (if so equipped).
ANTIFREEZE
In the winter when it is anticipated that the
temperature will drop below 32°F (0°C),
check the antifreeze to assure proper win-
ter protection. For additional information,
refer to “Engine cooling system” in the “Do-
it-yourself ” section of this manual.
BATTERY
This vehicle is equipped with a sealed
maintenance free battery. It is recom-
mended that you visit a NISSAN dealer for
service.
DRAINING OF COOLANT WATER
If the vehicle is to be lef t outside without
antifreeze, drain the cooling system, includ-
ing the engine block. Refill before operating
the vehicle. For additional information, refer
to “Changing engine coolant” in the “Do-it-
yourself ” section of this manual.
