2011 INFINITI QX light

●If wheels or tires other than the INFINITI rec-
ommended ones are used, the VDC system
may not operate properly and the VDC warn-
ing light
may illuminate.
● The VDC system is not a substitute for winter
tires or tire chains on a snow covered road.
VEHICLE DYNAMIC CONTROL (VDC)
OFF SWITCH
The vehicle should be driven with the Vehicle
Dynamic Control (VDC) system ON for most
driving conditions.
When the vehicle is stuck in mud or snow, the
VDC system reduces the engine output to re-
duce 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 Vehicle Dynamic Control (VDC)
system, push the VDC OFF switch. The VDC off
indicator light
will illuminate.
Push the VDC OFF switch again or restart the
engine to turn ON the system.

In the event of a roadside emergency, Roadside
Assistance Service is available to you. Please
refer to your Warranty Information Booklet
(U.S.) or Warranty & Roadside Assistance Infor-
mation Booklet (Canada) for details.To shut off the engine in an emergency situation
while driving perform the following procedure:
●
Rapidly push the push-button ignition
switch 3 consecutive times, or
● Push and hold the push-button ignition
switch for more than 2 seconds.TIRE PRESSURE MONITORING SYSTEM
(TPMS)
This vehicle is equipped with the Tire Pressure
Monitoring System (TPMS). It monitors tire
pressure of all tires except the spare. When the
low tire pressure warning light is lit and the
CHECK TIRE PRESSURE warning (if so equipped)
appears in the dot matrix liquid crystal display,
one or more of your tires is significantly under-
inflated. If the vehicle is being driven with low
tire pressure, the TPMS will activate and warn
you of it by the low tire pressure warning light.
This system will activate only when the vehicle
is driven at speeds above 16 MPH (25 km/h). For
more details, see “WARNING/INDICATOR LIGHTS
AND AUDIBLE REMINDERS” in the “2. Instru-
ments and controls” section, “TIRE PRESSURE
information” in the “4. Monitor, climate, audio,
phone and voice recognition systems” section
and “TIRE PRESSURE MONITORING SYSTEM
(TPMS)” in the “5. Starting and driving” section.

WARNING
●If the low tire pressure warning light illumi-
nates or LOW PRESSURE information is dis-
played on the monitor screen while driving,
avoid sudden steering maneuvers or abrupt
braking, reduce vehicle speed, pull off the
road to a safe location and stop the vehicle
as soon as possible. Driving with under-
inflated tires may permanently damage the
tires and increase the likelihood of tire fail-
ure. Serious vehicle damage could occur and
may lead to an accident and could result in
serious personal injury. Check the tire pres-
sure for all four tires. Adjust the tire pressure
to the recommended COLD tire pressure
shown on the Tire and Loading Information
label to turn the low tire pressure warning
light OFF. If the light still illuminates while
driving after adjusting the tire pressure, a
tire may be flat. If you have a flat tire, replace
it with a spare tire as soon as possible.
● When a spare tire is mounted or a wheel is
replaced, the TPMS will not function and the
low tire pressure warning light will flash for
approximately 1 minute. The light will re-
main on after 1 minute. Contact your INFINITI
retailer as soon as possible for tire replace-
ment and/or system resetting. ●
Replacing tires with those not originally
specified by INFINITI could affect the proper
operation of the TPMS.
● Do not inject any tire liquid or aerosol tire
sealant into the tires, as this may cause a
malfunction of the tire pressure sensors.
CHANGING A FLAT TIRE
If you have a flat tire, follow the instructions
below.
Stopping the vehicle
1. Safely move the vehicle off the road and
away from traffic.
2. Turn on the hazard warning flashers.
3. Park on a level surface and apply the parking brake. Move the selector lever to

4. Turn off the engine.
5. Raise the hood to warn other traffic, and to signal professional road assistance
personnel that you need assistance.
6. Have all passengers get out of the vehicle and stand in a safe place, away from
traffic and clear of the vehicle.
WARNING
●Make sure the parking brake is securely ap-
plied and the automatic transmission is in
the P (Park) position.
● Never change tires when the vehicle is on a
slope, ice or slippery areas. This is
hazardous.
● Never change tires if oncoming traffic is
close to your vehicle. Wait for professional
road assistance.

6-12In case of emergency

In order to maintain the appearance of your
vehicle, it is important to take proper care of it.
To protect the paint surface, wash your vehicle
as soon as you can:
●after a rainfall to prevent possible damage
from acid rain
● after driving on coastal roads
● when contaminants such as soot, bird drop-
pings, tree sap, metal particles or bugs get
on the paint surface
● when dust or mud builds up on the surface
Whenever possible, store or park your vehicle
inside a garage or in a covered area.
When it is necessary to park outside, park in a
shady area or protect the vehicle with a body
cover.
Be careful not to scratch the paint surface when
putting on or removing the body cover.WASHING
Wash dirt off the vehicle with a wet sponge and
plenty of water. Clean the vehicle thoroughly
using a mild soap, a special vehicle soap or
general purpose dishwashing liquid mixed with
clean, lukewarm (never hot) water.
CAUTION
● Do not use car washes that use acid in the
detergent. Some car washes, especially
brushless ones, use some acid for cleaning.
The acid may react with some plastic vehicle
components, causing them to crack. This
could affect their appearance, and also could
cause them not to function properly. Always
check with your car wash to confirm that acid
is not used.
● Do not wash the vehicle with strong house-
hold soap, strong chemical detergents,
gasoline or solvents.
● Do not wash the vehicle in direct sunlight or
while the vehicle body is hot, as the surface
may become water-spotted. ●
Avoid using tight-napped or rough cloths,
such as washing mitts. Care must be taken
when removing caked-on dirt or other for-
eign substances so the paint surface is not
scratched or damaged.
Rinse the vehicle again with plenty of clean
water.
Inside flanges, seams and folds on the doors,
hatches and hood are particularly vulnerable to
the effects of road salt. Therefore, these areas
must be regularly cleaned. Make sure that the
drain holes in the lower edge of the door are
open. Spray water under the body and in the
wheel wells to loosen the dirt and wash away
road salt.
Avoid leaving water spots on the paint surface
by using a damp chamois to dry the vehicle.
CLEANING EXTERIOR
7-2Appearance and care

Aluminum alloy wheels
Wash regularly with a sponge dampened in a
mild soap solution, especially during winter
months in areas where road salt is used. Salt
could discolor the wheels if not removed.
CAUTION
Follow the directions below to avoid staining or
discoloring the wheels:
●Do not use a cleaner that uses strong acid or
alkali contents to clean the wheels.
● Do not apply wheel cleaners to the wheels
when they are hot. The wheel temperature
should be the same as ambient temperature.
● Rinse the wheel to completely remove the
cleaner within 15 minutes after the cleaner is
applied.
CHROME PARTS
Clean chrome parts regularly with a non- abra-
sive chrome polish to maintain the finish.
TIRE DRESSING
INFINITI does not recommend the use of tire
dressings. Tire manufacturers apply a coating
to the tires to help reduce discoloration of the
rubber. If a tire dressing is applied to the tires,
it may react with the coating and form a com-
pound. This compound may come off the tire
while driving and stain the vehicle paint.
If you choose to use a tire dressing, take the
following precautions:
● Use a water-based tire dressing. The coating
on the tire dissolves more easily with an
oil-based tire dressing.
● Apply a light coat of tire dressing to help
prevent it from entering the tire
tread/grooves (where it would be difficult to
remove).
● Wipe off excess tire dressing using a dry
towel. Make sure the tire dressing is com-
pletely removed from the tire tread/grooves.
● Allow the tire dressing to dry as recom-
mended by tire dressing manufacturer. Occasionally remove loose dust from the inte-
rior trim, plastic parts and seats using a vacuum
cleaner or soft bristled brush. Wipe the vinyl
and leather surfaces with a clean, soft cloth
dampened in mild soap solution, then wipe
clean with a dry soft cloth.
Regular care and cleaning is required in order to
maintain the appearance of the leather.
Before using any fabric protector, read the
manufacturer’s recommendations. Some fabric
protectors contain chemicals that may stain or
bleach the seat material.
Use a cloth dampened only with water, to clean
the meter and gauge lens.
WARNING
Do not use water or acidic cleaners (hot steam
cleaners) on the seat. This can damage the seat
or occupant classification sensors. This can
also affect the operation of the air bag system
and result in serious personal injury.

When driving in areas using road salt or other
corrosive materials, check lubrication fre-
quently.
Lights*:Clean the headlights on a regular
basis. Make sure that the headlights, stop
lights, tail lights, turn signal lights, and other
lights are all operating properly and installed
securely. Also check headlight aim.
Road wheel nuts (lug nuts)*: When checking the
tires, make sure no wheel nuts are missing, and
check for any loose wheel nuts. Tighten if
necessary.
Tire rotation*: Tires should be rotated every
7,500 miles (12,000 km).
Tires*: Check the pressure with a gauge often
and always prior to long distance trips. If nec-
essary, adjust the pressure in all tires, includ-
ing the spare, to the pressure specified. Check
carefully for damage, cuts or excessive wear.
Tire Pressure Monitoring System (TPMS) trans-
mitter components: Replace the TPMS transmit-
ter grommet seal, valve core and cap when the
tires are replaced due to wear or age.
Tire, wheel alignment and balance: If the vehicle
should pull to either side while driving on a
straight and level road, or if you detect uneven
or abnormal tire wear, there may be a need for
wheel alignment. If the steering wheel or seat vibrates at normal
highway speeds, wheel balancing may be
needed.
For additional information regarding tires, refer
to “Important Tire Safety Information” (US) or
“Tire Safety Information” (Canada) in the
INFINITI Warranty Information Booklet.
Windshield:
Clean the windshield on a regular
basis. Check the windshield at least every six
months for cracks or other damage. Have a
damaged windshield repaired by a qualified
repair facility.
Windshield wiper blades*: Check for cracks or
wear if they do not wipe properly.
Inside the vehicle
The maintenance items listed here should be
checked on a regular basis, such as when
performing periodic maintenance, cleaning the
vehicle, etc.
Accelerator pedal: Check the pedal for smooth
operation and make sure the pedal does not
catch or require uneven effort. Keep the floor
mat away from the pedal.
Automatic transmission P (Park) mechanism: On
a fairly steep hill, check that your vehicle is held
securely with the selector lever in the P (Park)
position without applying any brakes. Brake pedal:
Check the pedal for smooth opera-
tion. If the brake pedal suddenly goes down
further than normal, the pedal feels spongy or
the vehicle seems to take longer to stop, see an
INFINITI retailer immediately. Keep the floor mat
away from the pedal.
Brakes: Check that the brakes do not pull the
vehicle to one side when applied.
Parking brake: Check the parking brake opera-
tion regularly. The vehicle should be securely
held on a fairly steep hill with only the parking
brake applied. If the parking brake needs ad-
justed, see an INFINITI retailer.
Seat belts: Check that all parts of the seat belt
system (for example, buckles, anchors, adjuster
and retractors) operate properly and smoothly,
and are installed securely. Check the belt web-
bing for cuts, fraying, wear or damage.
Seats: Check seat position controls such as
seat adjusters, seatback recliner, etc. to ensure
they operate smoothly and that all latches lock
securely in every position. Check that the head
restraints/headrests move up and down
smoothly and that the locks (if so equipped)
hold securely in all latched positions.
Steering wheel: Check for changes in the steer-
ing conditions, such as excessive free play,
hard steering or strange noises.
