2010 INFINITI QX check engine

Parking brake indicator
When the ignition switch is placed in the ON
position, the light comes on when the parking
brake is applied.
Low brake fluid warning light
When the ignition switch is in the ON position,
the light warns of a low brake fluid level. If the light
comes on while the engine is running with the
parking brake not applied, stop the vehicle and
perform the following:1. Check the brake fluid level. Add brake fluid as necessary. See “Brake fluid” in the “Main-
tenance and do-it-yourself” section of this
manual.
2. If the brake fluid level is correct, have the warning system checked by an INFINITI
dealer.
WARNING
●Your brake system may not be working
properly if the warning light is on. Driv-
ing could be dangerous. If you judge it
to be safe, drive carefully to the nearest
service station for repairs. Otherwise,
have your vehicle towed because driv-
ing it could be dangerous. ●
Pressing the brake pedal with the en-
gine stopped and/or a low brake fluid
level may increase your stopping dis-
tance and braking will require greater
pedal effort as well as pedal travel.
● If the brake fluid level is below the
MINIMUM or MIN mark on the brake
fluid reservoir, do not drive until the
brake system has been checked at an
INFINITI dealer.
Charge warning light
If this light comes on while the engine is running,
it may indicate the charging system is not func-
tioning properly. Turn the engine off and check
the generator belt. If the belt is loose, broken,
missing, or if the light remains on, see an INFINITI
dealer immediately.
CAUTION
● Do not ground electrical accessories
directly to the battery terminal. Doing
so will bypass the variable control sys-
tem and the vehicle battery may not
charge completely. Refer to “Variable
voltage control system” in the “Mainte-
nance and do-it-yourself” section later
in this manual. ●
Do not continue driving if the generator
belt is loose, broken or missing.
Check suspension warning
light
This light may indicate a malfunction in the auto-
leveling suspension.
For additional information, refer to “Jacking up
vehicle and removing the damaged tire” in the “In
case of emergency” section of this manual.
Engine oil pressure low/Engine coolant temperature
high warning light
This light warns of low engine oil pressure or high
engine coolant temperature.
If the light flickers or comes on during normal
driving, pull off the road in a safe area, stop the
engine and allow it to cool. If the light remains on
after checking the oil and coolant, stop the en-
gine immediately and call an INFINITI dealer or
other authorized repair shop.
This light is not designed to indicate a low
oil or low coolant level. Check the oil level
with the dipstick and check the coolant level on
the reservoir. See “Engine oil” and “Checking
engine coolant level” in the “Maintenance and

do-it-yourself” section of this manual. Also 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
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.
● If the gauge indicates engine coolant
temperature over the normal range,
stop the vehicle as soon as safely pos-
sible. If the engine is overheated, con-
tinued operation of the vehicle may se-
riously damage the engine. See “If your
vehicle overheats” in the “In case of
emergency” section for immediate ac-
tion required.
4WD warning light (

tion switch is placed in the ON position. It turns
off soon after the engine is started. If the engine or vehicle is not functioning properly,
the warning light will either remain illuminated or
blink. See “4WD warning light” in the “Starting
and driving” section.
CAUTION
●
If the warning light comes on or blinks
during operation, have your vehicle
checked by an INFINITI dealer as soon
as possible.

tank is getting low. Refuel as soon as it is conve-
nient, preferably before the fuel gauge reaches E
(Empty) . There will be a small reserve of fuel
in the tank when the fuel gauge needle
reaches E (Empty) .
Low tire pressure warning light
Your vehicle is equipped with a Tire Pressure
Monitoring System (TPMS) that monitors the tire
pressure of all tires except the spare.
The low tire pressure warning light warns of low
tire pressure or indicates that the TPMS is not
functioning properly.
After the ignition switch is placed in the ON
position, this light illuminates for about 1 second
and turns off.

Malfunction Indicator Light(MIL)
If this indicator light comes on steady or blinks
while the engine is running, it may indicate a
potential emission control malfunction.
The Malfunction Indicator Light may also come
on steady if the fuel-filler cap is loose or missing,
or if the vehicle runs out of fuel. Check to make
sure the fuel-filler cap is installed and closed
tightly, and that the vehicle has at least 3 gallons
(11.4 liters) of fuel in the fuel tank.
After a few driving trips, the
light should
turn off if no other potential emission control
system malfunction exists.
If this indicator light comes on steady for 20
seconds and then blinks for 10 seconds when
the engine is not running, it indicates that the
vehicle is not ready for an emission control sys-
tem inspection/maintenance test. See “Readi-
ness for inspection/maintenance (I/M) test” in the
“Technical and consumer information” section of
this manual. Operation
The malfunction indicator light will come on in
one of two ways:
● Malfunction indicator light on steady — An
emission control system malfunction has
been detected. Check the fuel-filler cap. If
the fuel-filler cap is loose or missing, tighten
or install the cap and continue to drive the
vehicle. The
light should turn off after
a few driving trips. If the
light does not
turn off after a few driving trips, have the
vehicle inspected by an INFINITI dealer. You
do not need to have your vehicle towed to
the dealer.
● Malfunction indicator light blinking — An en-
gine misfire has been detected which may
damage the emission control system. To re-
duce or avoid emission control system dam-
age:
– do not drive at speeds above 45 MPH (72 km/h) .
– avoid hard acceleration or deceleration.
– avoid steep uphill grades.
– if possible, reduce the amount of cargo being hauled or towed. The malfunction indicator light may stop blinking
and come on steady. Have the vehicle inspected
by an INFINITI dealer. You do not need to have
your vehicle towed to the dealer.
CAUTION
Continued vehicle operation without hav-
ing the emission control system checked
and repaired as necessary could lead to
poor driveability, reduced fuel economy,
and possible damage to the emission con-
trol system.
Security indicator light
This light blinks whenever the ignition switch is in
the LOCK, OFF or ACC position. This function
indicates the security system equipped on the
vehicle is operational.
For additional information, see “Security sys-
tems” later in this section.
Slip indicator light
This indicator light will blink when the traction
control system is limiting wheel spin. Slippery
road conditions may exist if the slip indicator
blinks on. If this happens, adjust your driving
accordingly.

The slip indicator light also comes on when you
turn the ignition switch to the ON position. The
light will turn off after about 2 seconds if the
system is operational. If the light does not come
on or does not go off, have the traction control
system checked by an INFINITI dealer.
Turn signal/hazard indicatorlights
The appropriate light flashes when the turn signal
switch is activated.
Both lights flash when the hazard switch is turned
on.
Vehicle Dynamic Control(VDC) OFF indicator light
This indicator light comes on when the Vehicle
Dynamic Control (VDC) OFF switch is pushed to
OFF, the transfer case is in the 4LO position
(
model) , or when the VDC system is not
functioning properly. This indicates the VDC sys-
tem is not operating.
Push the VDC OFF switch again or restart the
engine and the system will operate normally. See
“Vehicle Dynamic Control (VDC) system” in the
“Starting and driving” section of this manual. The VDC OFF light also comes on when you
place the ignition switch in the ON position. The
light will turn off after about 2 seconds if the
system is operational. If the light stays on or
comes on along with the SLIP indicator light
while you are driving, have the VDC system
checked by an INFINITI dealer.
While the VDC system is operating, you might
feel slight vibration or hear the system working
when starting the vehicle or accelerating, but this
is normal.
AUDIBLE REMINDERS
Brake pad wear warning
The disc brake pads have audible wear warnings.
When a disc brake pad requires replacement, it
makes a high pitched scraping sound when the
vehicle is in motion, whether or not the brake
pedal is depressed. Have the brakes checked as
soon as possible if the warning sound is heard.

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.

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.
