driving” section.
Tow mode should be used when pulling a heavy
trailer or hauling a heavy load. Driving the vehicle
in the tow mode with no trailer/load or light
trailer/light load will not cause any damage. How-
ever, fuel economy may be reduced, and the
transmission/engine driving characteristics may
feel unusual.
Press the tow mode switch to activate tow mode.
The indicator light on the tow mode switch illumi-
nates when tow mode is selected. Press the tow
mode switch again to turn tow mode OFF.

1. Apply the parking brake.
2. Move the shift selector to P (Park) or N(Neutral) . P (Park) is recommended.
The shift selector cannot be moved out
of P (Park) and into any of the other
gear positions if the ignition key is
turned to the OFF position or if the key
is removed from the ignition switch.
The starter is designed not to operate if
the shift selector is in any of the driving
positions.
3. Crank the engine with your foot off the
accelerator pedal by turning the ignition
key to START. Release the key when the
engine starts. If the engine starts, but fails to
run, repeat the above procedure.
● If the engine is very hard to start in ex-
tremely cold weather or when restarting,
depress the accelerator pedal a little (ap-
proximately 1/3 to the floor) and hold it
and then crank the engine. Release the
key and 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.
Crank the engine for 5 to 6 seconds. After
cranking the engine, release the accel- erator pedal. Crank the engine
with your
foot off the accelerator pedal by turn-
ing the ignition key to START. Release the
key when the engine starts. 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, turn the key off and wait 10
seconds before cranking again, otherwise
the starter could be damaged.
4. Allow the engine to idle for at least 30 sec- onds 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 shutting it
off. Starting and stopping the engine over a
short period of time may make the vehicle
more difficult to start.
ENGINE PROTECTION MODE
The engine has an engine protection mode to
reduce the chance of damage if the coolant tem-
perature becomes too high (for example, when
climbing steep grades in high temperature 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 operate) .
Engine power and, under some conditions, ve-
hicle 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 downshift 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 re- duced.
2. The air conditioning cooling function does not turn back ON.
3. The engine oil pressure warning/engine coolant temperature high indicator
il-
luminates, this may indicate a malfunction.
Move the vehicle off the road in a safe area
and allow the engine to cool. If after check-
ing the oil and coolant, the
remains
on, do not continue to drive and call an
INFINITI dealer.
The malfunction indicator lamp may also come
ON. You do not need to have your vehicle towed,
unless it remains on, but have it inspected soon
by an INFINITI dealer. See “Warning/Indicator
Lights and Audible reminders” in the “Instruments
and Controls” section of this manual.
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 col-
lision. Be especially careful when driving.
If the vehicle cannot maintain a safe driv-
ing 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” in the “In case of emer-
gency” section of this manual.
CAUTION
Running the engine with the engine oil
pressure warning light on could cause se-
rious damage to the engine almost imme-
diately. Such damage is not covered by
warranty. Turn off the engine as soon as it
is safe to do so.
AUTOMATIC TRANSMISSION
WARNING
● Do not depress the accelerator pedal
while shifting from P (Park) or N (Neu-
tral) to R (Reverse) , or L (Low) . 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 P (Park) or R (Reverse)
while the vehicle is moving. This could
cause an accident.
CAUTION
● When stopping the vehicle on an uphill
grade, do not hold the vehicle by de-
pressing the accelerator pedal. The foot
brake should be used for this purpose.
● Do not downshift abruptly on slippery
roads. This may cause a loss of control.
The automatic transmission in your vehicle is
electronically controlled to produce maximum
power and smooth operation.
