2010 INFINITI G37 engine

Remember, drinking and driving don’t mix! And
that is true for drugs, too (over-the-counter,
prescription, and illegal drugs). Don’t drive if
your ability to operate your vehicle is impaired
by alcohol, drugs, or some other physical con-
dition.
ALL-WHEEL DRIVE (AWD) DRIVING
SAFETY PRECAUTIONS WARNING● Do not drive beyond the performance capa-
bility of the tires, even with AWD engaged.
Accelerating quickly, sharp steering maneu-
vers or sudden braking may cause loss of
control.
● Always use tires of the same type, size,
brand, construction (bias, bias-belted or ra-
dial), and tread pattern on all four wheels.
Install tire chains on the rear wheels when
driving on slippery roads and drive carefully.
● This vehicle is not designed for offroad
(rough road) use. Do not drive on sandy or
muddy roads that tires may get stuck in. ● For AWD equipped vehicles, do not attempt
to raise two wheels off the ground and shift
the transmission to any D (Drive) or R (Re-
verse) position with the engine running. Do-
ing so may result in drivetrain damage or
unexpected vehicle movement which could
result in serious vehicle damage or personal
injury.
● Do not attempt to test an AWD equipped ve-
hicle on a 2-wheel dynamometer, (such as
the dynamometers used by some states for
emissions testing), or similar equipment
even if the other two wheels are raised off
the ground. Make sure you inform test facil-
ity personnel that your vehicle is equipped
with AWD before it is placed on a dynamom-
eter. Using the wrong test equipment may
result in drivetrain damage or unexpected
vehicle movement which could result in seri-
ous vehicle damage or personal injury.
● When a wheel is off the ground due to an
unlevel surface, do not spin the wheel
excessively. WARNINGDo not operate the push-button ignition switch
while driving the vehicle except in an emer-
gency. (The engine will stop when the ignition
switch is pushed 3 consecutive times or the
ignition switch is pushed and held for more
than 2 seconds.) If the engine stops while the
vehicle is being driven, this could lead to a
crash and serious injury.
Before operating the push-button ignition
switch, be sure to move the selector lever to the
P (Park) position (for automatic transmission
model) or the shift lever to the N (Neutral)
position (for manual transmission model).PUSH-BUTTON IGNITION SWITCH

AUTOMATIC TRANSMISSION
7 speed automatic transmission The automatic transmission in your vehicle is
electronically controlled by a transmission con-
trol module to produce maximum efficiency and
smooth operation.
Shown on the following pages are the recom-
mended operating procedures for this transmis-
sion. 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 selector lever button
before shifting the selector lever to the R (Re-
verse), N (Neutral), D (Drive), DS (Drive Sport) or
Manual shift mode position. Be sure the vehicle
is fully stopped before attempting to shift the
selector lever.
This automatic transmission model is designed
so that the foot brake pedal must be depressed
before shifting from P (Park) to any drive posi-
tion while the ignition switch position is ON.
The selector 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 selector 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 (Re-
verse), D (Drive), DS (Drive Sport) 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 cau-
tion when shifting into a forward or reverse
gear before the engine has warmed up.
● Never shift to P (Park) or R (Reverse) while
vehicle is moving forward. Never shift to P
(Park), D (Drive) or DS (Drive Sport) while
vehicle is moving rearward. Failure to do so
could cause you to lose control and have an
accident. CAUTION● 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.
● Do not downshift abruptly on slippery roads.
This may cause a loss of control.

: Push the button while depressing the
brake pedal,
: Push the button,
: Just move the selector lever.
After starting the engine, fully depress the
brake pedal and shift the selector lever from P
(Park) to R (Reverse), N (Neutral), D (Drive), DS
(Drive Sport) or Manual shift mode position. Push the button to shift into P (Park) or R
(Reverse). All other positions can be selected
without pushing the button.
WARNINGApply the parking brake if the selector lever is
in any position while the engine is not running.
Failure to do so could cause the vehicle to move
unexpectedly or roll away and result in serious
personal injury or property damage.
CAUTIONMake sure the vehicle is completely stopped
and the transmission is in the P (Park) position.
P (Park) position :
Use this selector position when the vehicle is
parked or when starting the engine. Make sure
the vehicle is completely stopped. The brake
pedal must be depressed and the selector lever
button pushed in to move the selector lever from
the N (Neutral) position or any drive position to
the P (Park) position. Apply the parking brake.
When parking on a hill, apply the parking brake
first, then move the selector lever to the P (Park)
position. CAUTIONUse this position only when the vehicle is com-
pletely stopped.
R (Reverse) :
Use this position to back up. Always be sure the
vehicle is completely stopped before selecting
the R (Reverse) position. The brake pedal must
be depressed and the selector lever button
pushed in to move the selector lever from the P
(Park) position, the N (Neutral) position or any
drive position to the R (Reverse) position.
N (Neutral) :
Neither forward nor reverse gear is engaged.
The engine can be started in this position. You
may shift to the N (Neutral) position and restart
a stalled engine while the vehicle is moving.
D (Drive) :
Use this position for all normal forward driving.Selector lever SSD0596

M
6 (6th) and M
5 (5th) :
Use this position when driving up long slopes,
or for engine braking when driving down long
slopes. M
4 (4th), M
3 (3rd) and M
2 (2nd) :
Use these positions for hill climbing or engine
braking on downhill grades. M
1 (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 selector lever rapidly to the same
side twice will shift the ranges in succes-
sion.
● In the manual shift mode, the transmission
may not shift to the selected gear. This helps
maintain driving performance and reduces
the chance of vehicle damage or loss of con-
trol.
When this situation occurs, the Automatic
Transmission (AT) position indicator light (on
the dot matrix liquid crystal display) will
blink and the chime will sound. ● In the manual shift mode, the transmission
automatically shifts down to 1st gear before
the vehicle comes to a stop. When accelerat-
ing 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, depend-
ing 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 condition.
If the vehicle is driven under extreme conditions,
such as excessive wheel spinning and subse-
quent 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 re-
turn to its normal operating condition. If it does
not return to its normal operating condition,
have an INFINITI retailer check the transmission
and repair if necessary. Shift lock release If the battery charge is low or discharged, the
selector lever may not be moved from the P
(Park) position even with the brake pedal de-
pressed and the selector lever button pushed.
To move the selector lever, perform the follow-
ing procedure:
1. Push the ignition switch to the OFF or
LOCK position.
2. Apply the parking brake.
3. Remove the shift lock cover
