In preparation for the next engine start, the
engine may have a slightly delayed shutoff
af ter placing the ignition switch in the
OFF position, depending on the driving
conditions.
NOTE:
The engine would NOT start within 3 sec-
onds of turning the engine off.
NOTE:
Care should be taken to avoid situations
that can lead to potential battery dis-
charge and potential no-start conditions
such as:
1. Installation or extended use of elec-tronic accessories that consume bat-
tery power when the engine is not
running (phone chargers, GPS, DVD
players, etc.).
2. The vehicle is not driven regularly and/or only driven short distances.
In these cases, the battery may need to
be charged to maintain battery health.
REMOTE ENGINE START (if so
equipped)
Vehicles started with the Remote Engine
Start require the ignition switch to be
placed in the ON position before the shif t
lever can be moved from the P (Park) posi-
tion. To place the ignition switch in the ON
position, follow these steps:
1. Make sure that the Intelligent Key is on you.
2. Apply the brake.
3. Push the ignition switch once to the ON position.
For additional information, see “NISSAN In-
telligent Key®” (P. 3-2).
ENGINE PROTECTION MODE
The engine has an engine protection mode
to reduce the chance of damage if the cool-
ant temperature becomes too high (for ex-
ample, when climbing steep grades in high
temperatures with heavy loads, such as
when towing a trailer). When the engine tem-
perature reaches a certain level:
• The engine coolant temperature gauge will move toward the H position.
• Engine power may be reduced.
• The air conditioning cooling function may be automatically turned off for a short
time (the blower will continue to operate).
Engine power and, under some conditions,
vehicle speed will decrease. Vehicle speed
can be controlled with the accelerator pedal,
but the vehicle may not accelerate at the
desired speed. The transmission will down-
shif t or upshif t as it reaches prescribed shif t
points. You can also shif t manually.
As driving conditions change and engine
coolant temperature is reduced, vehicle
speed can be increased using the accel-
erator pedal, and the air conditioning cool-
ing function will automatically be turned
back on.
DRIVING THE VEHICLE
5-18Starting and driving

The Malfunction Indicator Light (MIL) may
also come on if the engine coolant tem-
perature is not reduced or the air condi-
tioning cooling function does not turn back
on. Ifonly it remains on, you do not need to
have your vehicle towed, but have it in-
spected soon. It is recommended that you
visit a NISSAN dealer for this service. For
additional information, see “Malfunction In-
dicator Light (MIL)” (P. 2-19).
WARNING
Overheating can result in reduced en-
gine power and vehicle speed. The re-
duced speed may be lower than other
traffic, which could increase the chance
of a collision. Be especially careful
when driving. If the vehicle cannot
maintain a safe driving speed, pull to
the side of the road in a safe area. Allow
the engine to cool and return to normal
operation. For additional information,
see “If your vehicle overheats” (P. 6-13).
CAUTION
Running the engine with the engine oil
pressure warning light on could cause
serious damage to the engine almost
immediately. Such damage is not cov-
ered by warranty. Turn off the engine as
soon as it is safe to do so.
AUTOMATIC TRANSMISSION (A/T)
WARNING
• Do not depress the accelerator pedal
while shif ting from P (Park) or N (Neu-
tral) to R (Reverse), D (Drive). Always
depress the brake pedal until shif ting
is completed. Failure to do so could
cause you to lose control and have an
accident.
• Cold engine idle speed is high, so use
caution when shif ting into a forward
or reverse gear before the engine has
warmed up.
• Never shif t to either the P (Park) or R
(Reverse) position while the vehicle is
moving forward and P (Park) or D
(Drive) position while the vehicle is
reversing. This could cause an acci-
dent or damage the transmission. •
Do not downshif t abruptly on slip-
pery roads. This may cause a loss of
control.
• Except in an emergency, do not shif t
to the N (Neutral) position while driv-
ing. Coasting with the transmission
in the N (Neutral) position may cause
serious damage to the transmission.CAUTION
• To avoid possible damage to your ve-
hicle, when stopping the vehicle on
an uphill grade, do not hold the ve-
hicle by depressing the accelerator
pedal. The foot brake should be used
for this purpose.
The A/T in your vehicle is electronically con-
trolled to produce maximum power and
smooth operation.
The recommended operating procedures
for this transmission are shown on the fol-
lowing pages. Follow these procedures for
maximum vehicle performance and driv-
ing enjoyment.

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 possible.
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 ex- ceeding 60 mph (97 km/h) (where le-
gally allowed) can improve fuel effi-
ciency due to reduced aerodynamic
drag.
• Maintaining a safe following distance behind other vehicles reduces unnec-
essary braking.
• Safely monitoring traffic to anticipate changes in speed permits reduced
braking and smooth acceleration
changes.
• Select a gear range suitable to road conditions.
5. Use Cruise Control
• Using cruise control during highway driving helps maintain a steady speed.
• Cruise control is particularly effective in providing fuel savings when driving
on flat terrains.
6. Plan for the Shortest Route
• Utilize a map or navigation system to determine the best route to save time. 7.
Avoid Idling
• Shutting off your engine when safe for stops exceeding 30–60 seconds saves
fuel and reduces emissions.
8. Buy an Automated Pass for Toll Roads
• Automated passes permit drivers to use special lanes to maintain cruising
speed through the toll and avoid stop-
ping and starting.
9. Winter Warm Up
• Limit idling time to minimize impact to fuel economy.
• Vehicles typically need no more than 30 seconds of idling at start-up to ef-
fectively circulate the engine oil before
driving.
• Your vehicle will reach its ideal operat- ing temperature more quickly while
driving versus idling.
10. Keeping your Vehicle Cool
• Park your vehicle in a covered parking area or in the shade whenever
possible.
• When entering a hot vehicle, opening the windows will help to reduce the
inside temperature faster, resulting in
reduced demand on your A/C system.
FUEL EFFICIENT DRIVING TIPS
5-108Starting and driving

•When the temperature inside the ve-
hicle is lower than approximately 68°F
(20°C).
• When the temperature inside the ve-
hicle is higher than approximately 86°C
(30°F). (When the air conditioner is off,
the Idling Stop System will operate.)
• When the front defroster is turned on.
• When more than 3 minutes have
elapsed since the Idling Stop System
was active.
• When the accelerator pedal is
depressed.
• When the steering wheel is operated.
(The steering wheel operation may be-
come heavy, but this is not a
malfunction.)
• When the battery capacity is low.
• When the power consumption is high.
• When the shif t lever is any range other
than D (Drive).
• When the Idling Stop OFF switch is
pushed.NOTE:
The following condition will prevent the
Idling Stop System from automatically
restarting the engine. Starting the en-
gine with the ignition switch operation is
then necessary:
• The hood is open.
Use this system while waiting at a stop
light, etc. When the vehicle is stopped for
long periods of time, turn off the engine.
When the engine is stopped by the Idling
Stop System, heating, cooling and dehu-
midif ying functions will be deactivated. To
avoid the air conditioning functions from
being deactivated, turn off the Idling Stop
System by pushing the Idling Stop OFF
switch.
RETROGRADE MOVEMENT
CONTROL FUNCTION
This system is designed to reduce the ret-
rograde movement that occurs while the
driver’s foot changes from depressing the
brake pedal to the accelerator pedal when
moving the vehicle while the Idling Stop
System is active on a hilly road.
IDLING STOP SYSTEM DISPLAY
The status of the Idling Stop System can be
checked in the vehicle information display.
Starting and driving5-131

• When the Idling Stop System is deacti-vated af ter the engine has been auto-
matically stopped by the Idling Stop Sys-
tem, the engine will immediately restart if
suitable conditions are present. The en-
gine will then be prevented from auto-
matically stopping during the same
journey.
NOTE:
•The Idling Stop System ON or OFF mes-
sage is displayed for a few seconds in
the vehicle information display when
the Idling Stop System OFF switch is
pushed. For additional information, see
“Idling Stop System Display ” (P. 5-131).
• The Idling Stop System resets to ON every time the ignition switch is
switched from the OFF position to the
ON position.
• It is best to disable the ISS system when towing a trailer. You can do this
by pushing the Idling Stop OFF switch.
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,
see “Engine cooling system” (P. 8-6).
BATTERY
If the battery is not fully charged during
extremely cold weather conditions, the
battery fluid may freeze and damage the
battery. To maintain maximum efficiency,
the battery should be checked regularly.
For additional information, see “Battery”
(P. 8-16).
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, see
“Changing engine coolant” (P. 8-7).
TIRE EQUIPMENT
1. SUMMER tires have a tread designed to provide superior performance on dry
pavement. However, the performance of
these tires will be substantially reduced
in snowy and icy conditions. If you oper-
ate your vehicle on snowy or icy roads,
NISSAN recommends the use of MUD &
SNOW or ALL SEASON TIRES on all four
wheels. It is recommended that you visit
a NISSAN dealer for the tire type, size,
speed rating and availability information.
2. For additional traction on icy roads, studded tires may be used. However,
some U.S. states and Canadian prov-
inces prohibit their use. Check local,
state and provincial laws before install-
ing studded tires.
Skid and traction capabilities of studded
snow tires on wet or dry surfaces may be
poorer than that of non-studded snow
tires.
3. Tire chains may be used. For additional information, see “Tire chains” (P. 8-40).
