check engine light INFINITI QX 2010 User Guide

The vehicle should be driven with the Vehicle
Dynamic Control (VDC) system on for most driv-
ing 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 come on.
Push the VDC OFF switch again or restart the
engine to turn on the system. See “Vehicle Dy-
namic Control (VDC) system” in the “Starting and
driving” section.
WARNING
The rear sonar system is a convenience
but it is not a substitute for proper back-
ing. Always turn and check that it is safe to
do so before backing up. Always back up
slowly.
The rear sonar system is active when the ignition
switch is placed in the ON position and the shift
selector is in R (Reverse) .
When sensors detect obstacles within 5.9 ft (1.8
m) of the rear bumper, a beeping tone is emitted. The rear sonar system can be disabled by push-
ing the OFF switch. When the system is disabled,
the indicator light on the switch will illuminate.
The system will automatically reset the next time
the ignition switch is placed in the ON position.
See “Rear sonar system” in the “Starting and
driving” section.

tions. You could be burned or seriously
injured if it is misused or mishandled.
Always stop the engine and do not
smoke or allow open flames or sparks
near the vehicle when refueling.
● Do not attempt to top off the fuel tank
after the fuel pump nozzle shuts off
automatically. Continued refueling may
cause fuel overflow, resulting in fuel
spray and possibly a fire.
● Use only an original equipment type

INFINITI VEHICLE IMMOBILIZER
SYSTEM
The INFINITI Vehicle Immobilizer System will not
allow the engine to start without the use of the
registered key.
If the engine fails to start using the registered key,
it may be due to interference caused by another
registered key, an automated toll road device or
automated payment device on the key ring. Re-
start the engine using the following procedures:1. Leave the ignition switch in the ON position for approximately 5 seconds.
2. Turn the ignition switch to the OFF or LOCK position and wait approximately 5 seconds.
3. Repeat step 1 and 2 again. 4. Restart the engine while holding the device
(which may have caused the interference)
separate from the registered key.
If the no start condition re-occurs, INFINITI rec-
ommends placing the registered key on a sepa-
rate key ring to avoid interference from other
devices. ●
Make sure the area around the vehicle is
clear.
● Check fluid levels such as engine oil, cool-
ant, brake fluid, and window washer fluid as
frequently as possible, or at least whenever
you refuel.
● Check that all windows and lights are clean.
● Visually inspect tires for their appearance
and condition. Also check tires for proper
inflation.
● Check that all doors are closed.
● Position seat and adjust head restraint.
● Adjust inside and outside mirrors.
● Fasten seat belts and ask all passengers to
do likewise.
● Check the operation of warning lights when
the ignition switch is placed in the ON
D
position. See “Warning/indicator lights and
audible reminders” in the “Instruments and
controls” section of this manual.

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

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.

Shift lock release
If the battery is discharged, the shift selector may
not be moved from the P (Park) position even with
the brake pedal depressed.
To move the shift selector, release the shift lock.
The shift selector can be moved to N (Neutral) .
However, the steering wheel will be locked un-
less the ignition switch is turned to the ON posi-
tion. This allows the vehicle to be moved if the
battery is discharged.
To push the shift lock release, complete the fol-
lowing procedure:1. Place the ignition switch in the LOCK posi-
tion.
2. Apply the parking brake.
3. Remove the shift lock release cover as shown.
4. Insert a small screwdriver in the shift lock release slot and push down.
5. Move the shift selector to the N (Neutral) position while holding down the shift lock
release.
6. Turn the ignition switch to the ON position to unlock the steering wheel. Now the vehicle
may be moved to the desired location.

(Park) , have an INFINITI dealer check the auto-
matic transmission system as soon as possible.
WARNING
If the shift selector cannot be moved from
the P (Park) position while the engine is
running and the brake pedal is depressed,
the stop lights may not work. Malfunction-
ing stop lights could cause an accident
injuring yourself and others.
Accelerator downshift
— in D position —
For passing or hill climbing, depress the accel-
erator pedal to the floor. This shifts the transmis-
sion down into a lower gear, depending on the
vehicle speed.
Fail-safe
When the fail-safe operation occurs, please note
that the transmission will be locked in any of the
forward gears according to the condition.
If the vehicle is driven under extreme con-
ditions, 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, place the ignition
switch in the OFF position and wait for 3
seconds. Then turn 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 dealer check
the transmission and repair it if necessary.

●When cruising at highway speeds, it is more
economical to use the air conditioner and
leave the windows closed to reduce drag.
● For vehicles equipped with
, use 4H or
4L position only when necessary. Four-
wheel drive operation lowers fuel economy.
WARNING
● For 4WD equipped vehicles, do not at-
tempt to raise two wheels off the
ground and shift the transmission to
any drive or reverse position with the
engine running. Doing so may result in
drivetrain damage or unexpected ve-
hicle movement which could result in
serious vehicle damage or personal
injury.
● Do not attempt to test a 4WD equipped
vehicle 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 facility personnel
that your vehicle is equipped with 4WD
before it is placed on a dynamometer.
Using the wrong test equipment may
result in drivetrain damage or unex-
pected vehicle movement which could
result in serious vehicle damage or per-
sonal injury.
CAUTION
● Do not drive the vehicle in the 4H or 4LO
position on dry hard surface roads. Driv-
ing on dry, hard surfaces in 4H or 4LO
may cause unnecessary noise, tire wear
and increased fuel consumption.
If the 4WD warning light turns on when
you are driving on dry hard surface
roads:
– in the 4H position, shift the 4WD shift switch to 2WD.
– in the 4LO position, stop the vehicle, move the automatic transmission
shift selector to the N position and
shift the 4WD shift switch to 2WD
● If the warning light is still on after the
above operation, have your vehicle
checked by an INFINITI dealer as soon
as possible.
● The transfer case may be damaged if
you continue driving with the warning
light blinking.
