VANITY MIRROR
To use the front vanity mirror, pull down the
sun visor and pull up the cover.The automatic drive positioner system has
two features:
.
Entry/exit function
. Memory storage
ENTRY/EXIT FUNCTION
This system is designed so that the driver’s
seat and steering column will automatically
move when the shift lever is in the P (Park)
position. This allows the driver to get into
and out of the driver’s seat more easily.
The driver’s seat will slide backward and the
steering wheel will move up when the
driver’s door is opened with the ignition
switch in the LOCK position.
The driver’s seat and steering wheel will
return to the previous positions when the
ignition switch is pushed to the ACC posi-
tion.
The driver’s seat will not return to the
previous positions if the seat or steering
adjusting switch is operated when the seat is
at the exit position.
Cancel or activate entry/exit func-
tion
All the following conditions must be met
before cancelling or activating the entry/exit
function. .
The ignition switch is placed in the LOCK
position.
. The entry/exit function is not in opera-
tion.
. The following switches are not operated.
— Seat memory switches
— Power seat switches
— Electric tilting/telescopic steering wheel switch
The entry/exit function can be activated or
canceled by pushing and holding the SET
switch for more than 10 seconds.
The entry/exit function can also be acti-
vated or canceled if the [Lift Steering Wheel
on Exit] or [Slide Driver Seat Back on Exit]
key is turned to ON or OFF in the [Settings]
menu on the lower display. (See the INFINITI
InTouch
TMOwner’s Manual.)
Initialize entry/exit function
If the battery cable is disconnected, or if the
fuse opens, the entry/exit function will not
work though this function was set on before.
In such a case, after connecting the battery
or replacing with a new fuse, open and close
the driver’s door more than two times after
the ignition switch is switched from the ON
position to the LOCK position. The entry/
exit function will be activated.

dicator lights and audible reminders”
(P.2-10).)
BEFORE STARTING THE ENGINE

1. Apply the parking brake.
2. Move the shift lever to the P (Park) or N(Neutral) position. (P is recommended.)
The starter is designed not to operate
unless the shift lever is in either of the
above positions.
3. Push the ignition switch to the ON position. Firmly depress the brake pedal
and push the ignition switch to start the
engine.
To start the engine immediately, push
and release the ignition switch while
depressing the brake pedal with the
ignition switch in any position.
.If the engine is very hard to start inextremely cold weather or when re-
starting, depress the accelerator ped-
al a little (approximately 1/3 to the
floor) and while holding, crank the
engine. Release the accelerator pedal
when the engine starts.
.If the engine is very hard to start
because it is flooded, depress the
accelerator pedal all the way to the
floor and hold it. Push the ignition
switch to the ON position to start
cranking the engine. After 5 or 6
seconds, stop cranking by pushing
the ignition switch to OFF. After
cranking the engine, release the accel-
erator pedal. Crank the engine withyour foot off the accelerator pedal
by
depressing the brake pedal and push-
ing the push-button ignition switch to
start the engine. If the engine starts,
but fails to run, repeat the above
procedure.
CAUTION
Do not operate the starter for more than
15 seconds at a time. If the engine does
not start, push the ignition switch to
OFF and wait 10 seconds before crank-
ing again, otherwise the starter could be
damaged.
4. Warm-up
Allow the engine to idle for at least 30
seconds after starting. Do not race the
engine while warming it up. Drive at
moderate speed for a short distance
first, especially in cold weather. In cold
weather, keep the engine running for a
minimum of 2 - 3 minutes before shut-
ting it off. Starting and stopping the
engine over a short period of time may
make the vehicle more difficult to start.
When racing the engine up to 4,500 rpm
or more under no load condition, the
engine will enter the fuel cut mode. 5. To stop the engine, shift the shift lever to
the P (Park) position and push the
ignition switch to the OFF position.
NOTE:
Care should be taken to avoid situations
that can lead to potential battery discharge
and potential no-start conditions such as:
1. Installation or extended use of electro-
nic accessories that consume battery
power when the engine is not running
(Phone chargers, GPS, DVD players,
etc.)
2. Vehicle is not driven regularly and/or
only driven short distances.
In these cases, the battery may need to be
charged to maintain battery health.
REMOTE ENGINE START (if so
equipped)
Vehicles started with the remote engine
start function require the ignition switch to
be placed in the ON position before the shift
lever can be moved from the P (Park)
position. To place the ignition switch in the
ON position, perform the following steps:
1. Make sure that the Intelligent Key is on you.
2. Depress the brake pedal.
3. Push the ignition switch once to the ON position.
Starting and driving5-15
STARTING THE ENGINE

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.
