SIC4474
TOW mode should be used when pulling a
heavy trailer or hauling a heavy load. Driving
the vehicle in TOW mode with no trailer/
load or light trailer/light load will not cause
any damage. However, fuel economy may be
reduced, and the transmission/engine driv-
ing characteristics may feel unusual.
Push the TOW mode switch to activate
TOW mode. The indicator light in the vehicle
information display illuminates when TOW
mode is selected. Push the TOW mode
switch again to turn TOW mode off.
TOW mode is automatically canceled when
the ignition switch is placed in the OFF
position.
SIC4455
The vehicle should be driven with the Vehicle
Dynamic Control (VDC) system on for most
driving conditions.
If the vehicle is stuck in mud or snow, the
VDC system reduces the engine output to
reduce wheel spin. The engine speed will be
reduced even if the accelerator is depressed
to the floor. If maximum engine power is
needed to free a stuck vehicle, turn the VDC
system off.
To turn off the VDC system, push the VDC
OFF switch. The
indicator will illumi-
nate.
Push the VDC OFF switch again or restart
the engine to turn on the system. (See
“Vehicle Dynamic Control (VDC) system” (P.5-125).)

PROGRAMMING HomeLink®FOR
CANADIAN CUSTOMERS AND
GATE OPENERS
Canadian radio-frequency laws require
transmitter signals to “time-out” (or quit)
after several seconds of transmission –
which may not be long enough for
HomeLink
®to pick up the signal during
programming. Similar to this Canadian law,
some U.S. gate operators are designed to
“time-out” in the same manner.
If you live in Canada or you are having
difficulties programming a gate operator or
garage door opener by using the “Program-
ming HomeLink
®” procedures, replace “Pro-
gramming HomeLink®” Step 2 with the
following:
NOTE:
When programming a garage door opener,
etc., unplug the device during the “cycling”
process to prevent possible damage to the
garage door opener components.
Step 2: Using both hands, simultaneously
press and hold the desired HomeLink
®
button and the hand-held transmitter but-
ton. During programming, your hand-held
transmitter may automatically stop trans-
mitting. Continue to press and hold the
desired HomeLink
®button while you press
and re-press (“cycle”) your hand-held trans- mitter every two seconds until the frequency
signal has been learned. The HomeLink
®
indicator light will flash slowly and then
rapidly after several seconds upon success-
ful programming.
DO NOTrelease until the
HomeLink
®indicator light flashes slowly and
then rapidly. When the indicator light flashes
rapidly, both buttons may be released. The
rapid flashing indicates successful program-
ming.
Proceed with “Programming HomeLink
®”
step 3 to complete.
Remember to plug the device back in when
programming is completed.
OPERATING THE HomeLink®
UNIVERSAL TRANSCEIVER
The HomeLink®Universal Transceiver, after
it is programmed, can be used to activate the
programmed device. To operate, simply
press and release the appropriate pro-
grammed HomeLink
®Universal Transceiver
button. The amber indicator light will illumi-
nate while the signal is being transmitted.
For convenience, the hand-held transmitter
of the device may also be used at any time.

SET/memory switches
The automatic drive positioner system has
three features:
. Entry/exit function
. Memory storage
. Setting memory function
ENTRY/EXIT FUNCTION
This system is designed so that the driver’s
seat and steering column will automatically
move when the automatic transmission 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
The shift lever must be in the P (Park)
position with the ignition switch in the OFF
position.
The entry/exit function can be activated or
canceled by pressing 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 upon Exit” key or “Slide Driver Seat Back on Exit”
key is turned to ON or OFF in the [Settings]
menu on the lower display. (See 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 turned from the ON
position to the LOCK position. The entry/
exit function will be activated.
MEMORY STORAGE
Two positions for the driver’s seat, steering
column and outside mirrors can be stored in
the automatic drive positioner memory.
Follow these procedures to use the memory
system.
1. Move the shift lever to the P (Park)
position.
2. Adjust the driver’s seat, steering column and outside mirrors to the desired posi-
tions by manually operating each adjust-
ing switch. For additional information,
see “Seats” (P.1-3) and “Tilt/telescopic
steering” (P.3-29) and “Outside mirrors”
(P.3-37).

ENGINE PROTECTION MODE
The engine has an engine protection mode to
reduce the chance of damage if the coolant
temperature becomes too high (for example,
when climbing steep grades in high tem-
perature with heavy loads, such as when
towing a trailer).
When the engine temperature reaches a
certain level:
.The engine coolant temperature gauge
will move toward the H position.
. Engine power may be reduced.
. The air conditioning cooling function may
be automatically turned OFF for a short
time (the blower will continue to oper-
ate).
Engine power and, under some conditions,
vehicle speed will decrease. Vehicle speed
can be controlled with the accelerator pedal,
but the vehicle may not accelerate at the
desired speed. The transmission will down-
shift or upshift as it reaches prescribed shift
points. You can also shift manually.
As driving conditions change and engine
coolant temperature is reduced, vehicle
speed can be increased using the accelerator
pedal, and air conditioning cooling function
will automatically be turned back ON. If:
1. The engine coolant temperature is not
reduced.
2. The air conditioning cooling function does not turn back ON.
3. The engine oil pressure warning light
illuminates or engine coolant tempera-
ture gauge does not return to the normal
range from the H position, this may
indicate a malfunction. Move the vehicle
off the road to a safe area and allow the
engine to cool. If after checking the oil
and coolant, the
remains on or
engine coolant temperature does not
return to the normal range, do not
continue to drive. It is recommended
you contact an INFINITI retailer.
The Malfunction Indicator Light (MIL)
may also come ON. You do not need to have
your vehicle towed, unless it remains on, but
have it inspected soon. It is recommended
you visit an INFINITI retailer for this service.
See “Warning lights, indicator lights and
audible reminders” (P.2-11).
WARNING
Overheating can result in reduced engine
power and vehicle speed. The reduced
speed may be lower than other traffic, which could increase the chance of a
collision. Be especially careful when
driving. If the vehicle cannot maintain a
safe driving speed, pull to the side of the
road in a safe area. Allow the engine to
cool and return to normal operation. See
“If your vehicle overheats” (P.6-14).
CAUTION
Running the engine with the engine oil
pressure warning light on could cause
serious damage to the engine almost
immediately. Such damage is not cov-
ered by warranty. Turn off the engine as
soon as it is safe to do so.

AUTOMATIC TRANSMISSION
7 speed automatic transmission
The automatic transmission in your vehicle is
electronically controlled by a transmission
control module to produce maximum effi-
ciency and smooth operation.
Shown on the following pages are the
recommended operating procedures for this
transmission. Follow these procedures for
maximum vehicle performance and driving
enjoyment.
Starting the vehicle
After starting the engine, fully depress the
foot brake pedal and push the shift lever
button before shifting the shift lever to the R
(Reverse), N (Neutral), D (Drive) or Manual
shift mode position. Be sure the vehicle is
fully stopped before attempting to shift the
shift lever.
This automatic transmission model is de-
signed so that the foot brake pedal must be
depressed before shifting from P (Park) to
any drive position while the ignition switch
position is ON.
The shift lever cannot be moved out of the P
(Park) position and into any of the other
gear positions if the ignition switch is
pushed to the LOCK, OFF or ACC position.1. Keep the foot brake pedal depressed and
push the shift lever button to shift into a
driving gear.
2. Release the parking brake and foot brake, then gradually start the vehicle in
motion.
WARNING
.Do not depress the accelerator pedal
while shifting from P (Park) or N
(Neutral) to R (Reverse), D (Drive) or
manual shift mode. Always depress
the brake pedal until shifting is
completed. Failure to do so could
cause you to lose control and have
an accident.
. Cold engine idle speed is high, so use
caution when shifting into a forward
or reverse gear before the engine has
warmed up.
. Never shift to either P (Park) or R
(Reverse) position while the vehicle is
moving forward and P (Park) or D
(Drive) position while the vehicle is
moving reversing. This could cause an
accident or damage the transmission.
. Do not downshift abruptly on slip-
pery roads. This may cause a loss of
control.
CAUTION
.To avoid possible damage to your
vehicle; when stopping the vehicle on
an uphill grade, do not hold the
vehicle by depressing the accelerator
pedal. The foot brake should be used
for this purpose.
. Except in an emergency, do not shift
to the N (Neutral) position while
driving. Coasting with the transmis-
sion in the N (Neutral) position may
cause serious damage to the trans-
mission.

5-20Starting and driving
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
