engine INFINITI M 2010 Repair Manual

WARNING
Apply the parking brake if the selector lever is
in any position while the engine is not running.
Failure to do so could cause the vehicle to move
unexpectedly or roll away and result in serious
personal injury or property damage.
CAUTION
To prevent automatic transmission damage,
move the selector lever to the P (Park) or R
(Reverse) position only when the vehicle is
completely stopped.
P (Park) position :
Use this selector position when the vehicle is
parked or when starting the engine. Make sure
the vehicle is completely stopped. The brake
pedal must be depressed and the selector lever
button pushed in to move the selector lever from
the N (Neutral) position or any drive position to
the P (Park) position. Apply the parking brake.
When parking on a hill, apply the parking brake
first, then move the selector lever to the P (Park)
position. R (Reverse) :
Use this position to back up. Always be sure the
vehicle is completely stopped before selecting
the R (Reverse) position.
The brake pedal must
be depressed and the selector lever button
pushed in to move the selector lever from the P
(Park) position, the N (Neutral) position or any
drive position to the R (Reverse) position.
N (Neutral) :
Neither forward nor reverse gear is engaged.
The engine can be started in this position. You
may shift to the N (Neutral) position and restart
a stalled engine while the vehicle is moving.
D (Drive) :
Use this position for all normal forward driving.
DS (Drive Sport) mode
When the selector lever is shifted from the D
(Drive) position to the manual shift gate, the
transmission enters the DS (Drive Sport) mode.
This mode is designed for performance-oriented
driving.
In this mode, the transmission automatically
shifts to allow smooth acceleration and engine
braking on a winding road or on a hilly road. When canceling the DS mode, return the selec-
tor lever to the D (Drive) position. The transmis-
sion returns to the normal driving mode.
Manual shift mode
When the selector lever is shifted from the D
(Drive) position to the manual shift gate with
the vehicle stopped or while driving, the trans-
mission enters the manual shift mode. Shift
ranges can be selected manually by moving the
selector lever up or down.
c
When shifting up, move the selector lever to
the + (up) side. The transmission shifts to
the higher range.
c When shifting down, move the selector lever
to the 2(down) side. The transmission
shifts to the lower range.
c When canceling the manual shift mode, re-
turn the selector lever to the D (Drive) posi-
tion. The transmission returns to the normal
driving mode.
In the manual shift mode, the shift range is
displayed on the position indicator in the meter.

Precaution :
c Remember not to drive at high speeds for
extended periods of time in lower than 5th
gear (5-speed model) or 7th gear (7-speed
model). This reduces fuel economy. c
Moving the selector lever rapidly to the same
side twice will shift the ranges in succes-
sion.
c In the manual shift mode, the transmission
may not shift to the selected gear. This helps
maintain driving performance and reduces
the chance of vehicle damage or loss of con-
trol.
c In the manual shift mode, the transmission
automatically shifts down to 1st gear before
the vehicle comes to a stop. When accelerat-
ing again, it is necessary to shift up to the
desired range.
Accelerator downshift Ð In D (Drive)
position Ð
For passing or hill climbing, fully depress the
accelerator pedal to the floor. This shifts the
transmission down into the lower gear, depend-
ing on the vehicle speed.
Fail-safe
When the fail-safe operation occurs, note that
the transmission will be locked in any of the
forward gears according to the condition.
If the vehicle is driven under extreme conditions,
such as excessive wheel spinning and subse-
quent hard braking, the fail-safe system may be
activated. This will occur even if all electrical

The LDW and LDP systems monitor the lane
markers on the traveling lane using the camera
unit
s1located inside the front map light cover.
When the camera unit detects that the vehicle is
traveling close to either the left or the right of
the traveling lane, the lane departure warning
light
s2on the instrument panel blinks in
orange and a warning chime sounds. When the
LDP system is on, it will automatically apply the
brakes for a short period of time, using the
function of the Vehicle Dynamic Control (VDC)
system.
To turn on the LDW system, push the LDW
switch
s3. The LDW ON indicator lights4on the
switch will illuminate.

LANE DEPARTURE WARNING (LDW)
SYSTEM
Precautions on LDW system
WARNING
c This system is only a warning device to in-
form the driver of a potential unintended
lane departure. It will not steer the vehicle or
prevent loss of control. 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.
c The system will not operate at speeds below
approximately 45 MPH (72 km/h) or if it can-
not detect lane markers.
c If the LDW system malfunctions, it will can-
cel automatically, and the lane departure
warning light (orange) will illuminate.
c If the lane departure warning light (orange)
illuminates, pull off the road to a safe loca-
tion and stop the vehicle. Turn the engine off
and restart the engine. If the lane departure
warning light (orange) continues to illumi-
nate, have the system checked by an INFINITI

cThe LDP system will not operate at speeds
below approximately 45 MPH 72 km/h) or if it
cannot detect lane markers.
c The LDP system may not function properly
under the following conditions, and do not
use the LDP system:
± During bad weather (rain, fog, snow, wind, etc.).
± When driving on slippery roads, such as on ice or snow, etc.
± When driving on winding or uneven roads.
± When there is a lane closure due to road repairs.
± When driving in a makeshift lane.
± When driving on roads where the lane width is too narrow.
± When driving without normal tire condi- tions (for example, tire wear, low tire
pressure, installation of spare tire, tire
chains, non-standard wheels).
± When the vehicle is equipped with non- original brake parts or suspension parts. c
If the LDP system malfunctions, it will cancel
automatically. The lane departure warning
light (orange) on the instrument panel will
illuminate.
c If the lane departure warning light (orange)
illuminates, pull off the road to a safe loca-
tion and stop the vehicle. Turn the engine off
and restart the engine. If the warning light
(orange) continues to illuminate, have the
LDP system checked by an INFINITI retailer.
c Excessive noise will interfere with the warn-
ing chime sound, and the chime may not be
heard.
The functions of the LDP system (warning and
brake control assist) may or may not operate
properly under the following conditions:
c On roads where there are multiple parallel
lane markers; lane markers that are faded or
not painted clearly; yellow painted lane
markers; non-standard lane markers; or lane
markers covered with water, dirt, snow, etc.
c On roads where discontinued lane markers
are still detectable.
c On roads where there are sharp curves.
c On roads where there are sharply contrast-
ing objects, such as shadows, snow, water, wheel ruts, seams or lines remaining after
road repairs. (The LDP system could detect
these items as lane markers.)
c On roads where the traveling lane merges or
separates.
c When the vehicle's traveling direction does
not align with the lane marker.
c When traveling close to the vehicle in front
of you, which obstructs the lane camera unit
detection range.
c When rain, snow or dirt adheres to the
windshield in front of the lane camera unit.
c When the headlights are not bright due to
dirt on the lens or if the aiming is not
adjusted properly.
c When strong light enters the lane camera
unit. (For example, the light directly shines
on the front of the vehicle at sunrise or
sunset.)
c When a sudden change in brightness occurs.
(For example, when the vehicle enters or
exits a tunnel or under a bridge.)
While the LDP system is operating, you may
hear a sound of brake operation. This is normal
and indicates that the LDP system is operating
properly.

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

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.

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

light (orange) will come on and the ªCLEAN
SENSORº indicator will appear.
Action to take :
If the warning light comes on, park the vehicle
in a safe place, turn the engine off. Clean the
sensor window with a soft cloth and then
perform the settings again.Condition C :
When the ICC system is not operating properly,
the chime sounds and the ICC system warning
light (orange) will come on.
Action to take :
If the warning light comes on, park the vehicle
in a safe place. Turn the engine off, restart the
engine, resume driving and set the ICC system
again.
If it is not possible to set the system or the
indicator stays on, it may indicate that the ICC
system is malfunctioning. Although the vehicle
is still driveable under normal conditions, have
the vehicle checked at an INFINITI retailer.
