2010 INFINITI M engine

LDP system operation
The LDP system provides a lane departure warn-
ing and brake control assistance when the
vehicle is driven at speeds of approximately 45
MPH (72 km/h) and above. When the vehicle
approaches either the left or the right side of
the traveling lane, a warning chime will sound
and the lane departure warning light (orange)
on the instrument panel will blink to alert the
driver. Then, the LDP system will automatically
apply the brakes for a short period of time to
help assist the driver to return the vehicle to the
center of the traveling lane.The warning and assist functions will stop when
the vehicle returns to a position inside of the
lane marker.
To turn on the LDP system, push the LDP switch
on the steering wheel after starting the engine.
The LDP ON indicator light (green) on the instru-
ment panel will illuminate. Push the LDP switch
again to turn off the LDP system. The LDP ON
indicator light will turn off.

LANE CAMERA UNIT MAINTENANCE
The lane camera units1for the LDW/LDP
system is located inside the map light cover. To
keep the proper operation of the LDW/LDP
systems and prevent a system malfunction, be
sure to observe the following:
c Always keep the windshield clean.
c Do not attach a sticker (including transpar-
ent material) or install an accessory near the
camera unit.
c Do not place reflective materials, such as
white paper or a mirror, on the instrument
panel. The reflection of sunlight may ad-
versely affect the camera unit's capability of
detecting the lane markers. c
Do not strike or damage the areas around
the camera unit. Do not touch the camera
lens or remove the screw located on the
camera unit. If the camera unit is damaged
due to an accident, contact an INFINITI re-
tailer.
PRECAUTIONS ON CRUISE CONTROL
cIf the cruise control system malfunctions, it
will cancel automatically. The SET indicator
on the dot matrix crystal display will then
blink to warn the driver.
c If the engine coolant temperature becomes
excessively high, the cruise control system
will be canceled automatically.
c If the SET indicator blinks, turn the cruise
control main switch off and have the system
checked by your INFINITI retailer.
c The SET indicator may sometimes blink
when the cruise control main switch is
turned ON while pushing the
RESUME/ACCELERATE, SET/COAST or CAN-
CEL switch. To properly set the cruise control
system, perform the steps below in the order
indicated.
WARNING
Do not use the cruise control when driving un-
der the following conditions:
cwhen it is not possible to keep the vehicle at
a set speed
c in heavy traffic or in traffic that varies in
speed
c on winding or hilly roads

cThe distance to the vehicle ahead will
change according to the vehicle speed. The
higher the vehicle speed, the longer the
distance. c
If the engine is stopped, the set distance
becomes ªlongº. (Each time the engine is
started, the initial setting becomes ªlongº.)
Approach warning
If your vehicle comes closer to the vehicle
ahead due to rapid deceleration of that vehicle
or if another vehicle cuts in, the system warns
the driver with the chime and ICC system dis-
play. Decelerate by depressing the brake pedal
to maintain a safe vehicle distance if:
cThe chime sounds.
c The vehicle ahead detection and set dis-
tance indicator blink.
The warning chime may not sound in some
cases when there is a short distance between
vehicles. Some examples are:
c When the vehicles are traveling at the same
speed and the distance between vehicles is
not changing
c When the vehicle ahead is traveling faster
and the distance between vehicles is in-
creasing
c When a vehicle cuts in near your vehicle
The warning chime will not sound in the follow-
ing cases:
c When your vehicle approaches vehicles that
are parked or moving slowly.
c When the accelerator pedal is depressed,
overriding the system.

NOTE:
The approach warning chime may sound and the
system display may blink when the ICC sensor
detects some reflectors
sAwhich are fitted on
vehicles in other lanes or on the side of the road.
This may cause the ICC system to decelerate or
accelerate the vehicle. The ICC sensor may de-
tect these reflectors when the vehicle is driven
on winding roads, hilly roads or when entering
or exiting a curve. The ICC sensor may also de-
tect reflectors on narrow roads or in road con-
struction zones. In these cases you will have to
manually control the proper distance ahead of
your vehicle. Also, the sensor sensitivity can be affected by
vehicle operation (steering maneuver or driving
position in the lane) or traffic or vehicle condi-
tion (for example, if a vehicle is being driven
with some damage).
Automatic cancellation
A chime sounds under the following conditions
and the control is automatically canceled.
c
When the vehicle speed falls below approxi-
mately 20 MPH (32 km/h)
c When the selector lever is not in the D, DS or
Manual mode
c When the windshield wipers are operating at
low (LO) or high speed (HI). If the vehicle is
equipped with a rain sensing auto-wiper, the
system may cancel when the wipers are set
to intermittent (INT).
c When the SNOW mode switch is turned on
c When the VDC is turned off
c When the VDC operates
c When the engine coolant temperature be-
comes excessively high

PREVIEW FUNCTION (for Intelligent
Cruise Control system equipped
models)
The ICC system with the preview function iden-
tifies the need to apply emergency braking by
sensing the vehicle ahead in the same lane and
the distance to the vehicle ahead and relative
speed from it, it applies the brake pre-pressure
before the driver depresses the brake pedal and
helps improve brake response by reducing
pedal free play.
For more details, see ªBRAKE ASSISTº later in
this section.

CAUTION
During the first 1,200 miles (2,000 km), follow
these recommendations to obtain maximum
engine performance and ensure the future reli-
ability and economy of your new vehicle. Fail-
ure to follow these recommendations may re-
sult in shortened engine life and reduced
engine performance.
c Avoid driving for long periods at constant
speed, either fast or slow. Do not run the
engine over 4,000 rpm.
c Do not accelerate at full throttle in any gear.
c Avoid quick starts.
c Avoid hard braking as much as possible. c
Accelerate slowly and smoothly. Maintain
cruising speeds with a constant accelerator
position.
c Drive at moderate speeds on the highway.
Driving at high speed lowers fuel economy.
c Avoid unnecessary stopping and braking.
Keep a safe distance behind other vehicles.
c Select a gear range suitable to road condi-
tions.
c Avoid unnecessary engine idling.
c Keep your engine tuned up.
c Follow the recommended periodic mainte-
nance schedule.
c Keep the tires inflated to the correct pres-
sure. Low tire pressure increases tire wear
and lowers fuel economy.
c Keep the wheels in correct alignment. Im-
proper alignment increases tire wear and
lowers fuel economy.
c Climate control operation lowers fuel
economy. Use the air conditioner only when
necessary.
c When cruising at highway speeds, it is more
economical to use the air conditioner and
leave the windows closed to reduce drag. c
Use the recommended viscosity engine oil.
