Manual shift mode
When the shift lever is in the manual shift
gate, the transmission is ready for the
manual shift mode. Shift ranges can be
selected manually by moving the shift lever
up or down.
When shifting up, move the shift lever to the
+ (up) side. The transmission shifts to the
higher range.
When shifting down, move the shift lever to
the − (down) side. The transmission shifts to
the lower range.
When canceling the manual shift mode,
return the shift lever to the D (Drive)
position. The transmission returns to the
normal driving mode.
In the manual shift mode, the shift range is
displayed in the vehicle information display
between the speedometer and tachometer.
Shift ranges up or down one by one as
follows:
M1?
/M2 ?
/M3?
/M4 ?
/M5?
/M6?
/M7
M7 (7th):
Use this position for all normal forward
driving at highway speeds.
M6 (6th) andM5 (5th):
Use these positions when driving up long
slopes, or for engine braking when driving
down long slopes.
M4 (4th),M3 (3rd) andM2 (2nd):
Use these positions for hill climbing or engine
braking on downhill grades.
M1 (1st):
Use this position when climbing steep hills
slowly or driving slowly through deep snow,
or for maximum engine braking on steep
downhill grades.
. Remember not to drive at high speeds for
extended periods of time in lower than
7th gear. This reduces fuel economy.
. Moving the shift lever rapidly to the same
side twice will shift the ranges in succes-
sion.
. In the manual shift mode, the transmis-
sion may not shift to the selected gear
or may automatically shift to the other
gear. This helps maintain driving per-
formance and reduces the chance of
vehicle damage or loss of control.
. When the transmission does not shift to
the selected gear, the Automatic Trans-
mission (AT) position indicator (in the
vehicle information display) will blink
and the buzzer will sound. .
In the manual shift mode, the transmis-
sion automatically shifts down to 1st
gear before the vehicle comes to a stop.
When accelerating again, it is necessary
to shift up to the desired range.
Accelerator downshift — In D (Drive)
position —
For passing or hill climbing, fully depress the
accelerator pedal to the floor. This shifts the
transmission down into the lower gear,
depending 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 condi-
tion.
If the vehicle is driven under extreme
conditions, such as excessive wheel spinning
and subsequent hard braking, the fail-safe
system may be activated. This will occur
even if all electrical circuits are functioning
properly. In this case, push the switch to the
OFF position and wait for 3 seconds. Then
push the ignition switch back to the ON
position. The vehicle should return to its
normal operating condition. If it does not
return to its normal operating condition,
have the transmission checked and re-
paired, if necessary. It is recommended you

play. Use thebutton to select “Driver
Assistance”. Then push the OK button.
2. Select “Lane” and push the OK button.
3. Select “Warning(LDW)” and push the OK button.
The warning systems switch
is used to
turn on and off the LDW system when it is
activated on the vehicle information display.
When the warning systems switch
is
turned off, the warning systems ON indica-
tor light
on the switch is off.
The warning systems switch
will turn on
and off the LDW and BSW systems at the
same time.
NOTE:
If you disable the LDW system, the system
will remain disabled the next time you start
the vehicle’s engine.
LDW SYSTEM LIMITATIONS
WARNING
Listed below are the system limitations
for the LDW system. Failure to follow
the warnings and instructions for proper
use of the LDW system could result in
serious injury or death. .
The system will not operate at speeds
below approximately 37 MPH (60
km/h) or if it cannot detect lane
markers.
. Do not use the LDW system under
the following conditions as it may not
function properly:
— During bad weather (rain, fog, snow, etc.).
— When driving on slippery roads, such as on ice or snow.
— When driving on winding or un- even roads.
— When there is a lane closure due to road repairs.
— When driving in a makeshift or temporary lane.
— When driving on roads where the lane width is too narrow.
— When driving without normal tire conditions (for example, tire wear,
low tire pressure, installation of
spare tire, tire chains, non-stan-
dard wheels).
— When the vehicle is equipped with non-original brake parts or sus-
pension parts. — When towing a trailer or other
vehicle.
. The system may not function prop-
erly under the following conditions:
— On roads where there are multi- ple 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.
— On roads where discontinued lane markers are still detectable.
— On roads where there are sharp curves.
— On roads where there are sharply contrasting objects, such as sha-
dows, snow, water, wheel ruts,
seams or lines remaining after
road repairs. (The LDW system
could detect these items as lane
markers.)
— On roads where the traveling lane merges or separates.
— When the vehicle’s traveling di- rection does not align with the
lane marker.
— When traveling close to the ve- hicle in front of you, which ob-

tection range.
— When rain, snow, dirt or object adheres to the windshield in front
of the lane camera unit.
— When the headlights are not bright due to dirt on the lens or
if the aiming is not adjusted
properly.
— When strong light enters the lane camera unit. (For example, the
light directly shines on the front
of the vehicle at sunrise or sun-
set.)
— When a sudden change in bright- ness occurs. (For example, when
the vehicle enters or exits a tunnel
or under a bridge.)
SYSTEM TEMPORARILY UNA-
VAILABLE
Condition A:
If the vehicle is parked in direct sunlight
under high temperature conditions (over
approximately 104°F (40°C)) and then
started, the LDW system may be deacti-
vated automatically, the LDW indicator will
flash and the following message will appear in the vehicle information display.
.
“Not Available: High Camera Temp”
When the interior temperature is reduced,
the LDW system will resume operating
automatically and the LDW indicator will
stop flashing.
Condition B:
The warning function of the LDW system is
not designed to work under the following
conditions:
. When you operate the lane change signal
and change traveling lanes in the direc-
tion of the signal. (The LDW system will
become operable again approximately 2
seconds after the lane change signal is
turned off.)
. When the vehicle speed lowers to less
than approximately 37 MPH (60 km/h).
Action to take:
After the above conditions have finished and
the necessary operating conditions are sa-
tisfied, the LDW system will resume.SYSTEM MALFUNCTION
If the LDW system malfunctions, it will
cancel automatically and “Malfunction”
warning message will appear in the vehicle
information display. If the warning message
appears, pull off the road to a safe location
and stop the vehicle. Place the ignition switch in the OFF position and restart the
engine. If the warning message continues to
appear, have the system checked. It is
recommended that you visit an INFINITI
retailer for this service.

LDP SYSTEM OPERATION
The LDP system operates above approxi-
mately 37 MPH (60 km/h) and when the
lane markings are clear. When the vehicle
approaches either the left or the right side of
the traveling lane, steering wheel will vibrate
and the LDP indicator (orange) on the
vehicle information display will blink to alert
the driver. Then, the LDP system will auto-
matically 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.
To turn on the LDP system, push the
dynamic driver assistance switch on the
steering wheel after starting the engine.
The LDP ON indicator on the vehicle
information display will illuminate. Push the
dynamic driver assistance switch again to
turn off the LDP system. The LDP ON
indicator will turn off.

The lane camera unitfor the LDP system
is located above the inside mirror. To keep
the proper operation of the LDP system and
prevent a system malfunction, be sure to
observe the following:
. Always keep the windshield clean.
. Do not attach a sticker (including trans-
parent material) or install an accessory
near the camera unit.
. Do not place reflective materials, such as
white paper or a mirror, on the instru-
ment panel. The reflection of sunlight
may adversely affect the camera unit’s
capability of detecting the lane markers. .
