POSITIONS BEFORE STARTING THE NISSAN
PUREDRIVE™ HYBRID SYSTEM
Starting and driving5-3

1. Apply the parking brake.
2. Move the shift lever to P (Park) or N (Neu-tral) . P (Park) is recommended.
The NISSAN PUREDRIVE™ Hybrid Sys-
tem is designed not to operate if the
shift lever is in any of the driving posi-
tions.
3. Depress the brake pedal and push the igni- tion switch to start the hybrid system. The
READY to drive indicator will illuminate on
the meter.
When starting the hybrid system at
very low outside temperatures, the
READY to drive indicator light will flash
and it may take longer for the READY
to drive indicator light to illuminate.
When the READY to drive indicator
light is flashing, it cannot be shifted
out of P (Park) .
When the READY light is flashing, it
cannot move out of P (Park) . NOTE:
Do not start the vehicle in the N (Neutral)
position.
● The hybrid system may not start even with
the READY to drive indicator light illumi-
nated. Once the READY to drive indicator
light is illuminated you may begin driving the
vehicle.
NOTE:
Care should be taken to avoid situations
that can lead to potential 12-volt battery
discharge and potential no-start conditions
such as: 1. Installation or extended use of elec-
tronic accessories that consume 12-
volt battery power when the engine is
not running (Phone chargers, GPS,
DVD players, etc.)
2. Vehicle is not driven regularly and/or
only driven short distances.
In these cases, the 12-volt battery may
need to be charged to maintain 12-volt bat-
tery health. 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 commut-
ing and coast whenever possible
● Apply light pressure to the accelerator
pedal when driving on flat roads or down
hills
● Avoid pumping the breaks when slowing
the vehicle when possible
2. Maintain Constant Speed
● Look ahead to try and anticipate and mini-
mize stops
● Synchronizing your speed with traffic
lights allows you to reduce your number
of stops
● Maintaining a steady speed can minimize
red light stops and improve fuel efficiency
STARTING THE NISSAN PUREDRIVE™
HYBRID SYSTEM FUEL-EFFICIENT DRIVING TIPS
5-4Starting and driving

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
● Turn off air conditioning when it is not
necessary
4. Drive at Economical Speeds and Dis-
tances
● Observing the speed limit and not ex-
ceeding 60 MPH (97 km/h) (where le-
gally allowed) can improve fuel efficiency
due to reduced aerodynamic drag
● Maintaining a safe following distance be-
hind other vehicles reduces unnecessary
braking
● Safely monitoring traffic to anticipate
changes in speed permits reduced brak-
ing and smooth acceleration changes
● Select a gear range suitable to road con-
ditions
● Frequent short-distance driving can re-
duce fuel economy 5.
Use Cruise Control
● Using cruise control during highway driv-
ing 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 de-
termine 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 stopping 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 effec-
tively circulate the engine oil before driving
● Your vehicle will reach its ideal operating
temperature more quickly while driving
versus idling
● Park your vehicle in moderate ambient
temperatures when possible
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
11. Cargo
● Avoid transporting unnecessary luggage
in the vehicle
● Avoid carrying luggage in the roof rack
which can increase aerodynamic drag
12. Break-in
● Your vehicle may need a break-in period
for more than 4000 miles to improve the
fuel economy
● Avoid measuring fuel economy within ini-
tial 1200 miles
Starting and driving5-5

13.Use D (Drive)
● Use the D (Drive) and drive with the Over
Drive on as much as possible
● Driving with the Over Drive OFF or in the
L (Low) position may cause the engine to
run longer than necessary and reduce
fuel economy
This system uses microphones
1located inside
the vehicle to detect engine booming sound. The
system then automatically produces a muted en-
gine booming sound through the speakers and
woofer (if so equipped) to reduce engine boom-
ing sound.
NOTE:
To operate the active noise control system
properly:
● Do not cover the speakers or woofer (if so
equipped) .
● Do not cover the microphones.

●Do not change or modify speakers including
the woofer and any audio related compo-
nents such as the amplifier.
● Do not make any modification including
sound deadening or modifications around
the microphones or speakers.WARNING
Your brake system may not be working
properly if the hydraulic brake warning
light and the electronically controlled
brake system warning light is on. Driving
could be dangerous. If you judge it to be
safe, drive carefully to the nearest service
station for repairs. Otherwise, have your
vehicle towed because driving it could be
dangerous.
BRAKE PRECAUTIONS
Vacuum-assisted brakes
The brake booster aids braking by using engine
vacuum. If the hybrid system is turned off, you can
stop the vehicle by depressing the brake pedal.
However, greater foot pressure 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
downshift 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.
When applying the brakes, you may hear a sound
coming from the braking system. This is normal.
WARNING
While driving on a slippery surface, be
careful when braking, accelerating or
downshifting. Abrupt braking or acceler-
ating could cause the wheels to skid and
result in an accident.
BRAKE SYSTEM
Starting and driving5-7

Jump starting provides power to the 12–volt sys-
tem to allow the electrical systems to operate.
The electrical systems must be operating to allow
the Li-ion battery to be charged. Jump starting
does not charge the Li-ion battery.
To start the hybrid system with a booster battery,
the instructions and precautions below must be
followed.
WARNING
●The engine may start at any time with-
out warning when the ignition is on and
the hybrid system is in the READY
mode. When jump starting keep your
hands, clothing, hair and tools away
from fans, belts and any other parts that
can move to avoid personal injury.
● If done incorrectly, jump starting can
lead to a 12–volt battery explosion, re-
sulting in severe injury or death. It could
also damage your vehicle.
● Explosive hydrogen gas is always pres-
ent in the vicinity of the battery. Keep all
sparks and flames away from the
battery. ●
Do not allow battery fluid to come into
contact with eyes, skin, clothing or
painted surfaces. Battery fluid is a cor-
rosive sulfuric acid solution which can
cause severe burns. If the fluid should
come into contact with anything, imme-
diately flush the contacted area with
water.
● Keep 12–volt battery out of the reach of
children.
● The booster battery must be rated at
12 volts. Use of an improperly rated
battery can damage your vehicle.
● Whenever working on or near a battery,
always wear suitable eye protectors (for
example, goggles or industrial safety
spectacles) and remove rings, metal
bands, or any other jewelry. Do not lean
over the battery when jump starting.
● Do not attempt to jump start a frozen
battery. It could explode and cause se-
rious injury.
● Your vehicle has an automatic engine
cooling fan. It could come on at any
time. Keep hands and other objects
away from it. ●
Always follow the instructions below.
Failure to do so could result in damage
to the charging system and cause per-
sonal injury.
CAUTION
Do not attempt to jump start a hybrid
vehicle as a booster vehicle.

4. Apply the parking brake. Move the shift lever to P (Park) . Switch off all unnecessary elec-
trical systems (lights, heater, air conditioner,
etc.) . 5. Remove vent caps on the battery (if so
equipped) of the vehicle with battery for
booster. Cover the battery with an old
cloth
Fto reduce explosion hazard.
6. Connect jumper cables in the sequence il- lustrated (
B,C,D,E).
CAUTION
●Always connect positive () to positive
() and negative () to body ground (for
example, strut mounting bolt, engine
lift bracket, etc.) — not to the battery.
● Make sure the jumper cables do not
touch moving parts in the engine com-
partment and that the cable clamps do
not contact any other metal.
● Do not keep the starter motor engaged
for more than 10 seconds. If the engine
does not start right away, place the ig-
nition switch in the OFF position and
wait 10 seconds.
7. Start the engine of the booster vehicle and let it run for a few minutes.

the negative cable then the positive cable.
Have vehicle taken to dealership for
repair.9. After the green READY light in the meter display comes ON, carefully disconnect the
negative cable and then the positive cable.
10. Replace the vent caps (if so equipped) . Be sure to dispose of the cloth used to cover
the vent holes as it may be contaminated
with corrosive acid.
WARNING
●Do not continue to drive if your vehicle
overheats. Doing so could cause engine
damage or a vehicle fire.
● To avoid the danger of being scalded,
never remove the radiator or coolant
reservoir cap while the engine is still
hot. When the radiator or coolant reser-
voir cap is removed, pressurized hot
water will spurt out, possibly causing
serious injury.
● Do not open the hood if steam is com-
ing out.
If your vehicle is overheating (indicated by an
extremely high temperature gauge reading and
the illumination of the engine oil pressure/engine
coolant temperature high indicator light) , or if you
feel a lack of engine power, detect abnormal
noise, etc. take the following steps. 1. Move the vehicle safely off the road, apply the parking brake and move the shift lever to
P (Park) .
Do not turn the NISSAN PUREDRIVE™
Hybrid System off. 2. Turn off the air conditioner. Open all the
windows, move the heater or air conditioner
temperature control to maximum hot and fan
control to high speed.
3. Get out of the vehicle. Look and listen for steam or coolant escaping from the radiator
before opening the hood. (If steam or cool-
ant is escaping, turn off the engine.) Do not
open the hood further until no steam or
coolant can be seen.
4. Open the engine hood.
WARNING
If steam or water is coming from the en-
gine, stand clear to prevent getting
burned.
5. Also check if the cooling fan is running. The radiator hoses and radiator should not leak
water. If the coolant is leaking or the cooling
fan does not run, stop the hybrid system.
6. Visually check drive belts for damage or looseness. Also check if the cooling fan is
running. The radiator hoses and radiator
should not leak water. If coolant is leaking,
the water pump belt is missing or loose, or
the cooling fan does not run, stop the en-
gine.
IF YOUR VEHICLE OVERHEATS
