INTELLIGENT CRUISE CONTROL
(ICC) (for vehicles with ProPILOT
Assist)
WARNING
Failure to follow the warnings and instruc-
tions for proper use of the ICC system
could result in serious injury or death.
• The ICC system is only an aid to assist the
driver and is not a collision warning or
avoidance device. It is recommended for
highway use only and it is not intended
for city driving. It is the driver’s respon-
sibility to stay alert, drive safely, and be
in control of the vehicle at all times. •
There are limitations to the ICC system
capability. The ICC system does not
function in all driving, traffic, weather,
and road conditions. It is the driver’s re-
sponsibility to stay alert, drive safely,
keep the vehicle in the traveling lane, and
be in control of the vehicle at all times.
• Always observe posted speed limits and
do not set the speed over them.
• The ICC system does not react to sta-
tionary and slow moving vehicles.
• Always drive carefully and attentively
when using the ICC system. Read and
understand the Owner’s Manual thor-
oughly before using the ICC system. To
avoid serious injury or death, do not rely
on the system to prevent accidents or to
control the vehicle’s speed in emergency
situations. Do not use the ICC system
except in appropriate road and traffic
conditions.
5-84Starting and driving

When driving on the freeway at a set speed
and approaching a slower traveling vehicle
ahead, the ICC system adjusts the speed to
maintain the distance, selected by the driver,
from the vehicle ahead. If the vehicle ahead
changes lanes or exits the freeway, the ICC
system accelerates and maintains the speed
up to the set speed. Pay attention to the
driving operation to maintain control of the
vehicle as it accelerates to the set speed.
The vehicle may not maintain the set speed
on winding or hilly roads. If this occurs, you
will have to manually control the vehicle
speed.Normally when controlling the distance to a
vehicle ahead, the system automatically ac-
celerates or decelerates your vehicle accord-
ing to the speed of the vehicle ahead.
Depress the accelerator to properly acceler-
ate your vehicle when acceleration is required
for a lane change. Depress the brake pedal
when deceleration is required to maintain a
safe distance to the vehicle ahead due to
sudden braking or if a vehicle cuts in. Always
stay alert when using the ICC system.
No vehicle detected ahead
The driver sets the desired vehicle speed
based on the road conditions. The ICC sys-
tem maintains the set vehicle speed, similar to
standard cruise control, as long as no vehicle
is detected in the lane ahead. The ICC system
displays the set speed.

ICC system malfunction
If the ICC system malfunctions, it will be
turned off automatically, a chime will sound,
and the speed control status warning (or-
ange) will illuminate.
Action to take:
If the warning light comes on, stop the vehicle
in a safe place. Turn the engine off, restart
the engine and set the ICC system again. If it
is not possible to set the ICC system or the
indicator stays on, it may be a malfunction.
Although the normal driving can be contin-
ued, the ICC system should be inspected. It isrecommended that you visit an INFINITI re-
tailer for this service.
NOTE:
If the ICC system is temporarily unavailable,
the conventional cruise control mode may
still be used. For additional information, see
“Conventional (fixed speed) cruise control
mode” (P. 5-101).
ICC sensor maintenance
The radar sensor is located on the front of the
vehicle.
To keep the ICC system operating properly,
be sure to observe the following:
• Always keep the sensor area clean.
• Do not strike or damage the areas around
the sensor.
• Do not attach a sticker (including transpar- ent material) or install an accessory near
the sensor. This could cause failure or
malfunction.
• Do not attach metallic objects near the sensor area (brush guard, etc.). This could
cause failure or malfunction.

STEERING ASSIST
WARNING
Failure to follow the warnings and instruc-
tions for proper use of the Steering Assist
could result in serious injury or death.
• The Steering Assist is not a replacement
for proper driving procedures and is not
designed to correct careless, inattentive
or absent-minded driving. The Steering
Assist will not always steer the vehicle to
keep it in the lane. It is not designed to
prevent loss of control. It is the driver’s
responsibility to stay alert, drive safely,
keep the vehicle in the traveling lane, and
be in control of the vehicle at all times.
• As there is a performance limit to the
Steering Assist’s capability, never rely
solely on the system. The Steering Assist
does not function in all driving, traffic,
weather, and road conditions. Always
drive safely, pay attention to the opera-
tion of the vehicle, and manually control
your vehicle appropriately.
• The Steering Assist is intended for use on
well-developed freeways or highways
with gentle (moderate) curves. To avoid
risk of an accident, do not use this system
on local or non-highway roads. •
The Steering Assist only steers the ve-
hicle to maintain its position in the center
of a lane. The vehicle will not steer to
avoid objects in the road in front of the
vehicle or to avoid a vehicle moving into
your lane.
• It is the driver’s responsibility to stay
alert, drive safely, keep the vehicle in the
traveling lane, and be in control of the
vehicle at all times. Never take your
hands off the steering wheel when driv-
ing. Always keep your hands on the
steering wheel and drive your vehicle
safely.
• Always drive carefully and attentively
when using the Steering Assist. Read
and understand the Owner’s Manual
thoroughly before using the Steering As-
sist. To avoid serious injury or death, do
not rely on the system to prevent acci-
dents or to control the vehicle’s speed in
emergency situations. Do not use the
Steering Assist except in appropriate
road and traffic conditions.Steering Assist operation
The Steering Assist controls the steering sys-
tem to help keep your vehicle near the center
of the lane when driving. The Steering Assist
is combined with the Intelligent Cruise Con-
trol (ICC) system. For additional information,
see “Intelligent Cruise Control (ICC) (for ve-
hicles with ProPILOT Assist)” (P. 5-84).
The Steering Assist can be activated when
the following conditions are met:
• The ICC system is activated.
• Lane markers on both sides are clearly detected.
• A vehicle ahead is detected (when the ve- hicle is driven at speeds under 37 mph [60
km/h])
• The driver grips the steering wheel.
• The vehicle is driven at the center of the lane.
• The turn signals are not operated.
• The windshield wiper is not operated in the high (HI) speed operation (the steering as-
sist function is disabled after the wiper op-
erates for approximately 10 seconds).

CONVENTIONAL (fixed speed)
CRUISE CONTROL MODE
NOTE:
ProPILOT Assist provides no approach
warnings, automatic braking, or steering as-
sist in the conventional (fixed speed) cruise
control mode.
This mode allows driving at a speed between
25 to 90 mph (40 to 144 km/h) without
keeping your foot on the accelerator pedal.
WARNING
• In the conventional (fixed speed) cruise
control mode, a warning chime does not
sound to warn you if you are too close to
the vehicle ahead, as neither the pres-
ence of the vehicle ahead nor the vehicle-
to-vehicle distance is detected.
• Pay special attention to the distance be-
tween your vehicle and the vehicle ahead
of you or a collision could occur.
• Always confirm the setting in the ICC
system display.
• Do not use the conventional (fixed
speed) cruise control mode when driving
under the following conditions:
– When it is not possible to keep the
vehicle at a set speed –
In heavy traffic or in traffic that var-
ies in speed
– On winding or hilly roads
– On slippery roads (rain, snow, ice,
etc.)
– In very windy areas
• Doing so could cause a loss of vehicle
control and result in an accident.

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 number
of stops.
• Maintaining a steady speed can mini- mize red light stops and improve fuel
efficiency.
3. Use Air Conditioning (A/C) at Higher Ve-
hicle 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 unneces-
sary braking.
• Safely monitoring traffic to anticipate changes in speed permits reduced brak-
ing 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 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 operat- ing temperature more quickly while driv-
ing 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 in-
side temperature faster, resulting in re-
duced demand on your A/C system.
FUEL EFFICIENT DRIVING TIPS
5-132Starting and driving

•Watch for slippery spots (glare ice).
These may appear on an otherwise clear
road in shaded areas. If a patch of ice is
seen ahead, brake before reaching it. Try
not to brake while on the ice, and avoid
any sudden steering maneuvers.
• Do not use the cruise control on slippery
roads.
• Snow can trap dangerous exhaust gases
under your vehicle. Keep snow clear of
the exhaust pipe and from around your
vehicle.
ENGINE BLOCK HEATER (if so
equipped)
Engine block heaters are used to assist with
cold temperature starting.
The engine block heater should be used when
the outside temperature is 20°F (-7°C) or
lower.
WARNING
• Do not use your engine block heater with
an ungrounded electrical system or a
2-pronged adapter. You can be seriously
injured by an electrical shock if you use
an ungrounded connection.
• Disconnect and properly store the engine
block heater cord before starting the en-
gine. Damage to the cord could result in
an electrical shock and can cause serious
injury.
• Use a heavy-duty 3-wire, 3-pronged ex-
tension cord rated for at least 10 A. Plug
the extension cord into a Ground Fault
Interrupt (GFI) protected, grounded
110-VAC outlet. Failure to use the
proper extension cord or a grounded
outlet can result in a fire or electrical
shock and cause serious personal injury. To use the engine block heater:
1. Turn the engine off.
2. Open the hood and unwrap the engine
block heater cord.
3. Plug the engine block heater cord into a grounded 3-wire, 3-pronged extension
cord.
4. Plug the extension cord into a Ground Fault Interrupt (GFI) protected, grounded
110-volt AC (VAC) outlet.
5. The engine block heater must be plugged in for at least2-4hours, depending on
outside temperatures, to properly warm
the engine coolant. Use an appropriate
timer to turn the engine block heater on.
6. Before starting the engine, unplug and properly store the cord to keep it away
from moving parts.
