4M(4th), 3M(3rd) and 2M(2nd):
Use these positions for hill climbing or engine
braking on downhill grades.
1
M(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 ignition
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 repaired, if necessary. It is recom-
mended you visit an INFINITI retailer for
this service.

detect the lane markers for certain
roads, weather or driving conditions.
. Using Active Lane Control under
some conditions of road, lane marker
or weather, or if you attempt to
change lanes without using the lane
change signal could lead to an un-
expected system operation. In such
conditions, you need to correct the
vehicle’s direction with your steering
operation to avoid accidents.
. Active Lane Control will not operate
at speeds below approximately 45 MPH (70 km/h) or if it cannot detect
lane markers.
. Active Lane Control may not operate
properly and should not be used
under the following conditions:
— During bad weather (rain, fog, snow, etc.).
— When driving on slippery roads, such as on ice or snow, etc.
— When driving on winding or un- even 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 with a tire that is not within normal tire conditions
(for example, tire wear, low tire
pressure, installation of spare tire,
tire chains, non-standard wheels).
— When the vehicle is equipped with non-original steering parts or sus-
pension parts.
. Active Lane Control may or may not
operate properly 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
