Overdrive (O/D) OFF switch (if so
equipped)
When the O/D OFF switch is pushed with
the shif t lever in the D (Drive) position,
the
light in the instrument panel illu-
minates. For additional information, refer
to “Overdrive OFF indicator light” in the “In-
struments and controls” section of this
manual.
Use the overdrive OFF mode when you
need improved engine braking. To turn off the overdrive OFF mode, push
the O/D OFF switch again. The
indi-
cator light will turn off.
Each time the engine is started, or when
the shif t lever is moved to any position
other than D (Drive), the overdrive OFF
mode will be automatically turned off.
Accelerator downshif t
— in D (Drive) position —
For passing or hill climbing, depress the
accelerator pedal to the floor. This shif ts
the transmission down into a lower gear,
depending on the vehicle speed.
Fail-safe
If the vehicle is driven under extreme
conditions, such as excessive wheel
spinning and subsequent hard braking,
the fail-safe system may be activated.
The Malfunction Indicator Light (MIL)
may come on to indicate the fail-safe
mode is activated. For additional infor-
mation, refer to “Malfunction Indicator
Light (MIL)” in the “Instruments and con-
trols” section of this manual. This will oc-
cur even if all electrical circuits are func-
tioning properly. In this case, place the
ignition switch in the OFF position and
wait for 10 seconds. Then push the switch back to the ON position. The ve-
hicle should return to its normal operat-
ing condition. If it does not return to its
normal operating condition, have the
transmission checked and repaired, if
necessary. It is recommended that you
visit a NISSAN dealer for this service.
WARNING
When the high fluid temperature pro-
tection mode or fail-safe operation oc-
curs, vehicle speed may be gradually re-
duced. The reduced speed may be lower
than other traffic, which could increase
the chance of a collision. Be especially
careful when driving. If necessary, pull
to the side of the road at a safe place
and allow the transmission to return to
normal operation, or have it repaired if
necessary.

ICC SYSTEM OPERATION
The ICC system maintains a selected dis-
tance from the vehicle in front of you within
the speed range 0 to 90 mph (0 to
144 km/h) up to the set speed. The set
speed can be selected by the driver be-
tween 20 to 90 mph (32 to 144 km/h), based
on road conditions.
The vehicle travels at the set speed when
the road ahead is clear.
The ICC system is designed to maintain a
selected distance from the vehicle in front
of you and can reduce the speed to match
a slower vehicle ahead. The system will de-
celerate the vehicle as necessary and if the
vehicle ahead comes to a stop, the vehicle
decelerates to a standstill. However, the ICC
system can only apply up to 40% of the
vehicle’s total braking power.
This system should only be used when traf-
fic conditions allow vehicle speeds to re-
main fairly constant or when vehicle
speeds change gradually. If a vehicle
moves into the traveling lane ahead or if a
vehicle traveling ahead rapidly decelerates,
the distance between vehicles may be-
come closer because the ICC system can-
not decelerate the vehicle quickly enough.
If this occurs, the ICC system will sound a

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 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 cruis-
ing 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
effectively circulate the engine oil be-
fore driving
∙ Your vehicle will reach its ideal oper- ating 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 sys-
tem
11. ECO Mode
∙ The ECO mode helps to enhance the fuel economy by controlling the en-
gine and Continuously Variable
Transmission (if so equipped) opera-
tion automatically to avoid rapid ac-
celeration.

WARNING
Always follow the instructions below.
Failure to do so could result in damage
to the charging system and cause per-
sonal injury.1. If the booster battery is in another ve- hicle, position the two vehicles to bring
their batteries near each other.
Do not allow the two vehicles to
touch. 2. Apply the parking brake. Move the shif t
lever to N (Neutral) (manual transmis-
sion) or to P (Park) (CVT). Switch off all
unnecessary electrical systems (lights,
heater, air conditioner (if so equipped),
etc.).
3. Turn the ignition switch to the LOCK position.
4. Ensure the vent caps are level and tight.
5. Connect the jumper cables in the se- quence illustrated (
A,B,C,D).
CAUTION
∙ Always connect positive () to posi-tive ( ) and negative () to body
ground (for example, strut mounting
bolt, engine lif t bracket, etc.) — not to
the battery.
∙ Make sure the jumper cables do not touch moving parts in the engine
compartment and that the cable
clamps do not contact any other
metal.
6. Start the engine of the booster vehicle and let it run for a few minutes.
7. Keep the engine speed of the booster vehicle at about 2,000 rpm and start the
engine of the vehicle being jump
started.
CAUTION
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 3 to 4 seconds before trying again.
8. Af ter starting the engine, carefully dis- connect the negative cable and then
the positive cable.

CAUTION
∙ Do not push start this vehicle. Thethree-way catalyst may be damaged.
∙ Continuously Variable Transmission (CVT) models and Manual Transmis-
sion (M/T) cannot be push-started or
tow-started. Attempting to do so may
cause transmission damage
∙ For Manual Transmission (M/T) mod- els, never try to start the vehicle by
towing it. When the engine starts, the
forward surge could cause the vehicle
to collide with the tow vehicle. If your vehicle is overheating (indicated by
an extremely high temperature gauge
reading), or if you feel a lack of engine
power, detect abnormal noise, etc., take the
following steps.
WARNING
∙ Do not continue to drive if your vehicle
overheats. Doing so could cause en-
gine damage or a vehicle fire.
∙ To avoid the danger of being scalded, never remove the radiator cap while
the engine is still hot. When the radia-
tor cap is removed, pressurized hot
water will spurt out, possibly causing
serious injury.
∙ Do not open the hood if steam is com- ing out.
1. Move the vehicle safely off the road, ap- ply the parking brake and move the
shif t lever to N (Neutral) (manual trans-
mission) or to P (Park) (CVT).
Do not stop the engine.
2. Turn off the air conditioner (if so equipped). Open all the windows, move
the heater or air conditioner tempera-
ture 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 coolant is escaping, turn off
the engine.) Do not open the hood fur-
ther until no steam or coolant can be
seen.
4. Open the engine hood.
WARNING
If steam or water is coming from the
engine, stand clear to prevent getting
burned.
5. 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 cool-
ant is leaking, the water pump belt is
missing or loose, or the cooling fan
does not run, stop the engine.
WARNING
Be careful not to allow your hands, hair,
jewelry or clothing to come into contact
with, or get caught in, engine belts or
the engine cooling fan. The engine cool-
ing fan can start at any time.

6. Af ter the engine cools down, check thecoolant level in the engine coolant res-
ervoir with the engine running. Add
coolant to the engine coolant reservoir
if necessary. Have your vehicle re-
paired. It is recommended that you visit
a NISSAN dealer for this service. When towing your vehicle, all State (Provin-
cial in Canada) and local regulations for
towing must be followed. Incorrect towing
equipment could damage your vehicle.
Towing instructions are available from a
NISSAN dealer. Local service operators are
generally familiar with the applicable laws
and procedures for towing. To assure
proper towing and to prevent accidental
damage to your vehicle, NISSAN recom-
mends having a service operator tow your
vehicle. It is advisable to have the service
operator carefully read the following pre-
cautions:
WARNING
∙ Never ride in a vehicle that is being
towed.
∙ Never get under your vehicle af ter it has been lif ted by a tow truck.
CAUTION
∙ When towing, make sure that thetransmission, axles, steering system
and powertrain are in working condi-
tion. If any of these conditions apply,
dollies or a flatbed tow truck must be
used.
∙ Always attach safety chains before towing.
For additional information, refer to “Flat
towing” in the “Technical and consumer in-
formation” section of this manual.
