How to change the set vehicle
speed
The set vehicle speed can be adjusted.
To change to a faster cruising speed:
∙ Push and hold the RES+ switch. The set vehicle speed increases by approximately
5 mph (5 km/h).
∙ Push, then quickly release, the RES+ switch. Each time you do this, the set
speed increases by approximately 1 mph
(1 km/h). To change to a slower cruising speed:
∙ Push and hold the SET- switch. The set vehicle speed decreases by approxi-
mately 5 mph (5 km/h).
∙ Push, then quickly release, the SET- switch. Each time you do this, the set
speed decreases by approximately 1 mph
(1 km/h).
How to momentarily accelerate or
decelerate
∙ Depress the accelerator pedal when ac-celeration is required. Release the accel-
erator pedal to resume the previously set
vehicle speed.
∙ Depress the brake pedal when decelera- tion is required. Control by the ProPILOT
Assist system is canceled. Push the RES+
switch to resume the previously set ve-
hicle speed.

WARNING
When the accelerator pedal is depressed
and you are approaching the vehicle ahead,
the ICC system will neither control the
brake nor warn the driver with the chime
and display. The driver must manually con-
trol the vehicle speed to maintain a safe
distance to the vehicle ahead. Failure to do
so could result in severe personal injury or
death.
NOTE:
When you accelerate by depressing the ac-
celerator pedal or decelerate by pushing the
SET- switch and the vehicle travels faster
than the speed set by the driver, the set
speed vehicle indicator will blink.
How to change the set distance to
the vehicle ahead
The distance to the vehicle ahead can be
selected at any time.
Each time the DISTANCE switch
Ais
pushed, the set distance will change to long,
middle, short and back to long again in that
sequence.

2. Middle 150 (45)
3. Short 90 (30)
∙ The distance to the vehicle ahead changes automatically according to the
vehicle speed. The higher the vehicle
speed, the longer the distance.
∙ If the engine is stopped, the set distance becomes “long.” (Each time the engine is
started, the initial setting becomes
“long.”)

Failure to follow the warnings and instruc-
tions for proper use of the PFCW system
could result in serious injury or death.
∙ The PFCW system can help warn thedriver before a collision occurs but will
not avoid a collision. It is the driver’s re-
sponsibility to stay alert, drive safely and
be in control of the vehicle at all times.
The PFCW system can help alert the driver
when there is a sudden braking of a second
vehicle traveling in front of the vehicle ahead
in the same lane. The PFCW system uses a radar sensor
A
located on the front of the vehicle to measure
the distance to the vehicle ahead in the same
lane.

Follow these easy-to-use Fuel Efficient Driv-
ing 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 Dis-
tances
∙ 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.

CHANGING ENGINE OIL
1. Park the vehicle on a level surface andapply the parking brake.
2. Start the engine and let it idle until it reaches operating temperature, then
turn it off.
3. Remove the oil filler cap
Aby turning it
counterclockwise. 4. Remove clips
Band under-engine pro-
tector. 5. Place a large drain pan under the drain
plug
C.
6. Remove the drain plug
Cwith a wrench
by turning it counterclockwise and com-
pletely drain the oil.
If the engine oil filter is to be changed,
remove and replace it at this time. For
additional information, refer to “Chang-
ing engine oil filter” in this section.
∙ Waste oil must be disposed of properly.
∙ Check your local regulations.

Seat belts:Check that all parts of the seat
belt system (for example, buckles, anchors,
adjusters and retractors) operate properly
and smoothly, and are installed securely.
Check the belt webbing for cuts, fraying,
wear or damage.
Seats: Check seat position controls such as
seat adjusters, seatback recliner, etc., to en-
sure they operate smoothly and all latches
lock securely in every position. Check that the
head restraints/headrests move up and
down smoothly and the locks (if so equipped)
hold securely in all latched positions.
Steering wheel: Check for changes in the
steering system, such as excessive free play,
hard steering or strange noises.
Warning lights and chimes: Make sure all
warning lights and chimes are operating
properly.
Windshield defroster: Check that the air
comes out of the defroster outlets properly
and in sufficient quantity when operating the
heater or air conditioner.
Windshield wiper and washer*: Check that
the wipers and washer operate properly and
that the wipers do not streak.Under the hood and vehicle
The maintenance items listed here should be
checked periodically (for example, each time
you check the engine oil or refuel).
Battery (except for maintenance free bat-
teries)*: Check the fluid level in each cell. It
should be between the MAX and MIN lines.
Vehicles operated in high temperatures or
under severe conditions require frequent
checks of the battery fluid level.
NOTE:
Care should be taken to avoid situations
that can lead to potential battery discharge
and potential no-start conditions such as:
1. Installation or extended use of elec-
tronic accessories that consume 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 battery may need to be
charged to maintain battery health.
Brake fluid level*: Make sure that the brake
fluid level is between the MAX and MIN lines
on the reservoir. Engine coolant level*:
Check the coolant level
when the engine is cold.
Engine drive belt*: Make sure the drive belt is
not frayed, worn, cracked or oily.
Engine oil level*: Check the level after parking
the vehicle on a level spot and turning off the
engine. Wait more than 15 minutes for the oil
to drain back into the oil pan.
Exhaust system: Make sure there are no
loose supports, cracks or holes. If the sound
of the exhaust seems unusual or there is a
smell of exhaust fumes, immediately have the
exhaust system inspected. It is recommended
that you visit an INFINITI retailer for this
service. For additional information, refer to
“Exhaust gas (carbon monoxide)” in the
“Starting and driving” section of this manual.
Fluid leaks: Check under the vehicle for fuel,
oil, water or other fluid leaks after the vehicle
has been parked for a while. Water dripping
from the air conditioner after use is normal. If
you should notice any leaks or if fuel fumes
are evident, check for the cause and have it
corrected immediately.
9-4Maintenance and schedules

To help ensure smooth, safe and economical
driving, INFINITI provides two maintenance
schedules that may be used, depending upon
the conditions in which you usually drive.
These schedules contain both distance and
time intervals, up to 90,000 miles
(144,000 km)/144 months. For most
people, the odometer reading will indicate
when service is needed. However, if you drive
very little, your vehicle should be serviced at
the regular time intervals shown in the sched-
ule.
After 90,000 miles
(144,000 km)/144 months, continue main-
tenance at the same mileage/time intervals.
ADDITIONAL MAINTENANCE
ITEMS FOR SEVERE OPERATING
CONDITIONS
Additional maintenance items for severe op-
erating conditionsshould be performed on
vehicles that are driven under especially de-
manding conditions. Additional maintenance
items should be performed if you primarily
operate your vehicle under the following con-
ditions:
∙ Repeated short trips of less than 5 miles (8 km). ∙ Repeated short trips of less than 10 miles
(16 km) with outside temperatures re-
maining below freezing.
∙ Operating in hot weather in stop-and-go “rush hour” traffic.
∙ Extensive idling and/or low speed driving for long distances, such as police, taxi or
door-to-door delivery use.
∙ Driving in dusty conditions.
∙ Driving on rough, muddy or salt spread roads.
∙ Towing a trailer, using a camper or a car-top carrier.
NOTE:
For vehicles operated in Canada, both stan-
dard and severe maintenance items should
be performed at every interval.
OIL CONTROL SYSTEM
Your vehicle is equipped with oil control sys-
tem. It calculates engine oil and filter change
intervals based on driving conditions. Driving
in the following severe conditions will shorten
the engine oil and filter change interval.
