For Canada
This device complies with Industry
Canada licence-exempt RSS standard(s).
Operation is subject to the following two
conditions:
1.This device may not cause
interference,
2. This device must accept any interfer-
ence, including interference that may
cause undesired operation of the
device.WARNING
Failure to follow the warnings and in-
structions for proper use of the I-DA
system could result in serious injury or
death.
• The I–DA system is only a warning to
inform the driver of a potential lack
of driver attention or drowsiness. It
will not steer the vehicle or prevent
loss of control.
• The I–DA system does not detect and
provide an alert of the driver’s lack of
attention or fatigue in every
situation.
• It is the driver’s responsibility to:
– stay alert,
– drive safely,
– keep the vehicle in the traveling lane,
– be in control of the vehicle at all times,
– avoid driving when tired,
– avoid distractions (texting, etc). The I–DA system helps alert the driver if the
system detects a lack of attention or driv-
ing fatigue.
The system monitors driving style and
steering behavior over a period of time,
and it detects changes from the normal
pattern. If the system detects that driver
attention is decreasing over a period of
time, the system uses audible and visual
warnings to suggest that the driver take a
break.

INTELLIGENT DRIVER ALERTNESS
SYSTEM OPERATION
If the system detects driver fatigue or that
driver attention is decreasing, the mes-
sage “Take a break?” appears in the vehicle
information display and a chime sounds
when the vehicle is driven at speeds above
37 mph (60 km/h).
The system continuously monitors driver
attention and can provide multiple warn-
ings per trip.The system resets and starts reassessing
driving style and steering behavior when
the ignition switch is cycled from the ON to
the OFF position and back to the ON posi-
tion.

INTELLIGENT DRIVER ALERTNESS
(I-DA) SYSTEM LIMITATIONS

System malfunction
If the Intelligent Driver Alertness system
malfunctions, the system warning mes-
sage will appear in the vehicle information
display and the function will be stopped
automatically.Action to take
Stop the vehicle in a safe location, place the
vehicle in P (Park) position, turn the engine
off and restart the engine. If the system
warning message continues to appear,
have the system checked. It is recom-
mended that you visit a NISSAN dealer for
this service.

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 pos-
sible
• 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
5-110Starting and driving

11.ECO Mode
• The ECO mode helps to enhance the fuel economy by controlling the en-
gine and Continuously Variable Trans-
mission (if so equipped) operation au-
tomatically to avoid rapid
acceleration. • Keep your engine tuned up.
• Follow the recommended scheduled
maintenance.
• 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.
• Use the recommended viscosity engine oil. For additional information, refer to “En-
gine oil and oil filter recommendations” in
the “Technical and consumer informa-
tion” section of this manual.

WARNING
• Do not stop or park the vehicle over
flammable materials such as dry
grass, waste paper or rags. They may
ignite and cause a fire. •
Safe parking procedures require that
both the parking brake be set and the
transmission placed in P (Park) for
Continuously Variable Transmission
(CVT) models or in an appropriate
gear for manual transmission (M/T)
models. Failure to do so could cause
the vehicle to move unexpectedly or
roll away and result in an accident.
Make sure the shif t lever has been
pushed as far forward as it can go
and cannot be moved without de-
pressing the foot brake pedal.
• Never leave the engine running while
the vehicle is unattended. •
Do not leave children unattended in-
side the vehicle. They could unknow-
ingly activate switches or controls or
make the vehicle move. Unattended
children could become involved in
serious accidents.
• To help avoid risk of injury or death
through unintended operation of the
vehicle and/or its systems, do not
leave children, people who require
the assistance of others or pets unat-
tended in your vehicle. Additionally,
the temperature inside a closed ve-
hicle on a warm day can quickly be-
come high enough to cause a signifi-
cant risk of injury or death to people
and pets.
1. Firmly apply the parking brake.
2. M/T models
Place the shif t lever in the R (Reverse)
position. When parking on an uphill
grade, place the shif t lever in 1st gear.
CVT models
Move the shif t lever into the P (Park) po-
sition.

PARKING/PARKING ON HILLS

3. To help prevent the vehicle from rollinginto traffic when parked on an incline, it
is a good practice to turn the wheels as
illustrated.
• HEADED DOWNHILL WITH CURB
O1:
Turn the wheels into the curb and
move the vehicle forward until the
curb side wheel gently touches the
curb.
• HEADED UPHILL WITH CURB
O2:
Turn the wheels away from the curb
and move the vehicle back until the
curb side wheel gently touches the
curb.
• HEADED UPHILL OR DOWNHILL, NO CURB
O3:
Turn the wheels toward the side of the
road so the vehicle will move away
from the center of the road if it moves.
4. Place the ignition switch in the LOCK po- sition and remove the key.

The brake system has two separate hy-
draulic circuits. If one circuit malfunctions,
you will still have braking at two wheels.
BRAKE PRECAUTIONS
Vacuum assisted brakes
The brake booster aids braking by using
engine vacuum. If the engine stops, you
can stop the vehicle by depressing the
brake pedal. However, greater foot pres-
sure on the brake pedal will be required to
stop the vehicle and stopping distance will
be longer.
Using the brakes
Avoid resting your foot on the brake pedal
while driving. This will overheat the brakes,
wear out the brake pads faster, and reduce
gas mileage.
To help reduce brake wear and to prevent
the brakes from overheating, reduce speed
and downshif t to a lower gear before going
down a slope or long grade. Overheated
brakes may reduce braking performance
and could result in loss of vehicle control.
