2010 INFINITI QX gas type

NOTE:
The lift gate must be unlocked in order to
open the glass hatch.
WARNING
Do not drive with the glass hatch open.
This could allow dangerous exhaust gases
to be drawn into the vehicle. See “Exhaust
gas” in the “Starting and driving” section
of this manual.
FUEL-FILLER CAP
The fuel-filler cap is a ratcheting type. Turn the
cap counterclockwise to remove. To tighten, turn
the cap clockwise until ratcheting clicks are
heard.
Put the fuel-filler cap on the cap holder
1while
refueling.
WARNING
● Gasoline is extremely flammable and
highly explosive under certain condi-
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
fuel-filler cap as a replacement. It has a
built-in safety valve needed for proper
operation of the fuel system and emis-
sion control system. An incorrect cap
can result in a serious malfunction and
possible injury. It could also cause the
malfunction indicator light to come on.
● Never pour fuel into the throttle body to
attempt to start your vehicle.

CAUTION
●Do not use leaded gasoline. Deposits
from leaded gasoline will seriously re-
duce the three-way catalyst’s ability to
help reduce exhaust pollutants.
● Keep your engine tuned up. Malfunc-
tions in the ignition, fuel injection, or
electrical systems can cause overrich
fuel flow into the three-way catalyst,
causing it to overheat. Do not keep driv-
ing if the engine misfires, or if notice-
able loss of performance or other un-
usual operating conditions are
detected. Have the vehicle inspected
promptly by an INFINITI dealer.
● Avoid driving with an extremely low fuel
level. Running out of fuel could cause
the engine to misfire, damaging the
three-way catalyst.
● Do not race the engine while warming it
up.
● Do not push or tow your vehicle to start
the engine.
ON-PAVEMENT AND OFF-ROAD
DRIVING PRECAUTIONS
Utility vehicles have a significantly higher
rollover rate than other types of vehicles.
They have higher ground clearance than passen-
ger cars to make them capable of performing in a
variety of on-pavement and off-road applications.
This gives them a higher center of gravity than
ordinary cars. An advantage of higher ground
clearance is a better view of the road, allowing
you to anticipate problems. However, they are not
designed for cornering at the same speeds as
conventional two-wheel drive vehicles any more
than low-slung sports cars are designed to per-
form satisfactorily under off-road conditions. If at
all possible, avoid sharp turns at high speeds. As
with other vehicles of this type, failure to operate
this vehicle correctly may result in loss of control
or vehicle rollover. In a rollover crash, an unbelted
person is significantly more likely to die than a
person wearing a seat belt.
Be sure to read the driving safety precautions
later in this section.
TIRE PRESSURE MONITORING
SYSTEM (TPMS)
Each tire, including the spare (if provided) ,
should be checked monthly when cold and in-
flated to the inflation pressure recommended by
the vehicle manufacturer on the vehicle placard
or tire inflation pressure label. (If your vehicle has
tires of a different size than the size indicated on
the vehicle placard or tire inflation pressure label,
you should determine the proper tire inflation
pressure for those tires.)
As an added safety feature, your vehicle has been
equipped with a tire pressure monitoring system
(TPMS) that illuminates a low tire pressure telltale
when one or more of your tires is significantly
under-inflated. Accordingly, when the low tire
pressure telltale illuminates, you should stop and
check your tires as soon as possible, and inflate
them to the proper pressure. Driving on a signifi-
cantly under-inflated tire causes the tire to over-
heat and can lead to tire failure. Under-inflation
also reduces fuel efficiency and tire tread life, and
may affect the vehicle’s handling and stopping
ability.

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.

Operation is subject to the following two
conditions: (1) This device may not cause
harmful interference, and (2) this device
must accept any interference received, in-
cluding interference that may cause undes-
ired operation of the device.HEADLIGHTS
Replacing the xenon headlight bulb
(Low-beam)
If replacement is required, see an INFINITI dealer.
WARNING
HIGH VOLTAGE
When xenon headlights are on, they pro-
duce a high voltage. To prevent an electric
shock, never attempt to modify or disas-
semble. Always have your xenon head-
lights replaced at an INFINITI dealer. For
additional information, see “Headlight
and turn signal switch” in the “Instru-
ments and controls” section.
Replacing the halogen headlight bulb
(High-beam)
The headlight is a semi-sealed beam type which
uses a replaceable headlight (halogen) bulb. Be-
cause the headlight assembly must be removed
from the vehicle for bulb replacement, see your
INFINITI dealer.
CAUTION
●High pressure halogen gas is sealed
inside the halogen bulb. The bulb may
break if the glass envelope is scratched
or the bulb is dropped.
● When handling the bulb, do not touch
the glass envelope.
● DO NOT TOUCH THE BULB WITH BARE
HANDS.
● Use the same number and wattage as
shown in the chart.
● Do not leave the bulb out of the head-
light reflector for a long period of time
as dust, moisture and smoke may enter
the headlight body and affect the per-
formance of the headlight.
● Aiming is not necessary after replacing
the bulb. When aiming adjustment is
necessary, contact an INFINITI dealer.
Fog may temporarily form inside the lens of the
exterior lights in the rain or in a car wash. A
temperature difference between the inside and
the outside of the lens causes the fog. This is not
a malfunction. If large drops of water collect
inside the lens, contact an INFINITI dealer.
