2010 INFINITI QX coolant

OPERATING TIPS
●When the engine coolant temperature and
outside air temperature are low, the air flow
from the foot outlets may not operate for a
maximum of 150 seconds. However, this is
not a malfunction. After the coolant tempera-
ture warms up, air flow from the foot outlets
will operate normally.
The sunload sensor
1, located on the top center
of the instrument panel, helps the system main-
tain a constant temperature. Do not put anything
on or around this sensor. Rear seat temperature and fan speed can be
controlled from both the front seat overhead con-
sole controls
Aor the rear seat overhead con-
sole controls
B.
Press the REAR CTRL button to transfer control
of the rear climate functions to the rear passen-
gers.
To operate the rear air conditioner, the engine
must be running.
If the rear seat fan control dial is set to (0) , the air
conditioner is turned off. If it is set to any of the fan
speed positions, air is discharged from the rear
vents at the corresponding speed.

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.

DRAINING OF COOLANT WATER
If the vehicle is to be left outside without anti-
freeze, drain the cooling system, including the
engine block. Refill before operating the vehicle.
For details, see “Changing engine coolant” in the
“Maintenance and do-it-yourself” section of this
manual.
TIRE EQUIPMENT
1. SUMMER tires have a tread designed toprovide superior performance on dry pave-
ment. However, the performance of these
tires will be substantially reduced in snowy
and icy conditions. If you operate your ve-
hicle on snowy or icy roads, INFINITI recom-
mends the use of MUD & SNOW or ALL
SEASON TIRES on all four wheels. Please
consult an INFINITI dealer for the tire type,
size, speed rating and availability informa-
tion.
2. For additional traction on icy roads, studded tires may be used. However, some U.S.
states and Canadian provinces prohibit their
use. Check local, state and provincial laws
before installing studded tires.
Skid and traction capabilities of studded
snow tires on wet or dry surfaces may be
poorer than that of non-studded snow tires. 3. Tire chains may be used. For details see
“Tire chains” in the “Maintenance and do-it-
yourself” section of this manual.
SPECIAL WINTER EQUIPMENT
It is recommended that the following items be
carried in the vehicle during winter:
● A scraper and stiff-bristled brush to remove
ice and snow from the windows and wiper
blades.
● A sturdy, flat board to be placed under the
jack to give it firm support.
● A shovel to dig the vehicle out of snowdrifts.
● Extra window washer fluid to refill the reser-
voir tank.
DRIVING ON SNOW OR ICE
WARNING
● Wet ice (32°F, 0°C and freezing rain) ,
very cold snow or ice can be slick and
very hard to drive on. The vehicle will
have much less traction or “grip” under
these conditions. Try to avoid driving on
wet ice until the road is salted or
sanded. ●
Whatever the condition, drive with cau-
tion. Accelerate and slow down with
care. If accelerating or downshifting too
fast, the drive wheels will lose even
more traction.
● Allow more stopping distance under
these conditions. Braking should be
started sooner than on dry pavement.
● Allow greater following distances on
slippery roads.
● Watch for slippery spots (glare ice) .
These may appear on an otherwise
clear road in shaded areas. If a patch of
ice is seen ahead, brake before reach-
ing it. Try not to brake while on the ice,
and avoid any sudden steering
maneuvers.
● Do not use the cruise control on slip-
pery roads.
● Snow can trap dangerous exhaust
gases under your vehicle. Keep snow
clear of the exhaust pipe and from
around your vehicle.

ENGINE BLOCK HEATER (if so
equipped)
Engine block heaters are available through
INFINITI dealers to assist in cold temperature
starting. The engine block heater should be used
when the outside temperature is 20° F (-7° C) or
lower.
To use the engine block heater:1. Turn the engine off.
2. Open the hood and unwrap the engine block heater cord.
3. Plug the engine block heater cord into a grounded 3-wire, 3-pronged extension
cord.
4. Plug the extension cord into a Ground Fault Interrupt (GFI) protected, grounded 110-
volt AC (VAC) outlet.
5. The engine block heater must be plugged in for at least2-4hours, depending on outside
temperatures, to properly warm the engine
coolant. Use an appropriate timer to turn the
engine block heater on.
6. Before starting the engine, unplug and prop- erly store the cord to keep it away from
moving parts.
WARNING
●Do not use your engine block heater
with an ungrounded electrical system
or a 2-pronged adapter. You can be se-
riously injured by an electrical shock if
you use an ungrounded connection.
● Disconnect and properly store the en-
gine block heater cord before starting
the engine. Damage to the cord could
result in an electrical shock and can
cause serious injury.
● Use a heavy-duty 3-wire, 3-pronged ex-
tension cord rated for at least 10 A. Plug
the extension cord into a Ground Fault
Interrupt (GFI) protected, grounded
110-VAC outlet. Failure to use the
proper extension cord or a grounded
outlet can result in a fire or electrical
shock and cause serious personal
injury.

WARNING
Do not push start this vehicle. The three-
way catalyst may be damaged.
CAUTION
Automatic transmission models cannot
be push-started or tow-started. Attempt-
ing to do so may cause transmission
damage.
WARNING
●Do not continue to drive if your vehicle
overheats. Doing so could cause engine
damage or a vehicle fire.
● To avoid the danger of being scalded,
never remove the radiator or coolant
reservoir cap while the engine is still
hot. When the radiator or coolant reser-
voir cap is removed, pressurized hot
water will spurt out, possibly causing
serious injury.
● Do not open the hood if steam is com-
ing out.
If your vehicle is overheating (indicated by an
extremely high temperature gauge reading and
the illumination of the engine oil pressure/engine
coolant temperature high indicator light) , or if you
feel a lack of engine power, detect abnormal
noise, etc. take the following steps. 1. Move the vehicle safely off the road, apply the parking brake and move the shift selector
to P (Park) .
Do not stop the engine.
2. Turn off the air conditioner. Open all the windows, move the heater or air conditioner
temperature control to maximum hot and fan
control to high speed. 3. Get out of the vehicle. Look and listen for
steam or coolant escaping from the radiator
before opening the hood. (If steam or cool-
ant is escaping, turn off the engine.) Do not
open the hood further until no steam or
coolant can be seen.
4. Open the engine hood.
WARNING
If steam or water is coming from the en-
gine, stand clear to prevent getting
burned.
5. Visually check drive belts for damage or looseness. Also check if the cooling fan is
running. The radiator hoses and radiator
should not leak water. If coolant is leaking,
the water pump belt is missing or loose, or
the cooling fan does not run, stop the en-
gine.
WARNING
Be careful not to allow your hands, hair,
jewelry or clothing to come into contact
with, or get caught in, engine belts or the
engine cooling fan. The engine cooling
fan can start at any time.

6. After the engine cools down, check the cool-ant level in the engine coolant reservoir tank
with the engine running. Add coolant to the
engine coolant reservoir tank if necessary.
Have your vehicle repaired at an INFINITI
dealer. When towing your vehicle, all State (Provincial in
Canada) and local regulations for towing must be
followed. Incorrect towing equipment could dam-
age your vehicle. Towing instructions are avail-
able from an INFINITI dealer. Local service opera-
tors are generally familiar with the applicable laws
and procedures for towing. To assure proper
towing and to prevent accidental damage to your
vehicle, INFINITI recommends having a service
operator tow your vehicle. It is advisable to have
the service operator carefully read the following
precautions:
WARNING
●
Never ride in a vehicle that is being
towed.
● Never get under your vehicle after it has
been lifted by a tow truck.
CAUTION
● When towing, make sure that the trans-
mission, axles, steering system and
powertrain are in working condition. If
any of these conditions apply, dollies or
a flatbed tow truck must be used.
● Always attach safety chains before
towing. For information about towing your vehicle behind
a recreational vehicle (RV) , refer to “Flat towing”
in the “Technical and consumer information” sec-
tion of this manual.
