light INFINITI QX70 2014 Owner's Manual

The Vehicle Dynamic Control (VDC) system
uses various sensors to monitor driver
inputs and vehicle motion. Under certain
driving conditions, the VDC system helps
to perform the following functions.
.Controls brake pressure to reduce tire
slip on one slipping drive wheel so
power is transferred to a non slipping
drive wheel on the same axle.
. Controls brake pressure and engine
output to reduce drive wheel slip based
on vehicle speed (traction control func-
tion).
. Controls brake pressure at individual
wheels and engine output to help the
driver maintain control of the vehicle in
the following conditions:
— understeer (vehicle tends to not
follow the steered path despite
increased steering input)
— oversteer (vehicle tends to spin due
to certain road or driving condi-
tions).
The VDC system can help the driver to
maintain control of the vehicle, but it
cannot prevent loss of vehicle control in
all driving situations.
When the VDC system operates, the VDC
warning light
in the instrument panel flashes so note the following:
.
The road may be slippery or the system
may determine some action is required
to keep the vehicle on the steered path.
. You may feel a pulsation in the brake
pedal and hear a noise or vibration
from under the hood. This is normal
and indicates that the VDC system is
working properly.
. Adjust your speed and driving to the
road conditions.
See “Vehicle Dynamic Control (VDC) warn-
ing light” (P.2-19) and “Vehicle Dynamic
Control (VDC) off indicator light” (P.2-21).
If a malfunction occurs in the system, the
VDC warning light
illuminates in the
instrument panel. The VDC system auto-
matically turns off.
The VDC OFF switch is used to turn off the
VDC system. The VDC off indicator
illuminates to indicate the VDC system is
off. When the VDC switch is used to turn off
the system, the VDC system still operates
to prevent one drive wheel from slipping by
transferring power to a non slipping drive
wheel. The VDC warning light
flashes if
this occurs. All other VDC functions are off,
and the VDC warning light
will not
flash. The VDC system is automatically reset to on when the ignition switch is
placed in the off position then back to the
on position.
See
“Vehicle Dynamic Control (VDC) warn-
ing light” (P.2-19) and “Vehicle Dynamic
Control (VDC) off indicator light” (P.2-21)
The computer has a built-in diagnostic
feature that tests the system each time you
start the engine and move the vehicle
forward or in reverse at a slow speed.
When the self-test occurs, you may hear a
“clunk” noise and/or feel a pulsation in the
brake pedal. This is normal and is not an
indication of a malfunction.
WARNING
. The VDC system is designed to help the
driver maintain stability but does not
prevent accidents due to abrupt steering
operation at high speeds or by careless
or dangerous driving techniques. Reduce
vehicle speed and be especially careful
when driving and cornering on slippery
surfaces and always drive carefully.
. Do not modify the vehicle’s suspension.
If suspension parts such as shock
absorbers, struts, springs, stabilizer

bars, bushings and wheels are not
INFINITI recommended for your vehicle
or are extremely deteriorated, the VDC
system may not operate properly. This
could adversely affect vehicle handling
performance, and the VDC warning light
may illuminate.
. If brake related parts such as brake
pads, rotors and calipers are not INFINITI
recommended or are extremely deterio-
rated, the VDC system may not operate
properly and the VDC warning light
may illuminate.
. If engine control related parts are not
INFINITI recommended or are extremely
deteriorated, the VDC warning light
may illuminate.
. When driving on extremely inclined
surfaces such as higher banked corners,
the VDC system may not operate prop-
erly and the VDC warning light
may
illuminate. Do not drive on these types
of roads.
. When driving on an unstable surface
such as a turntable, ferry, elevator or
ramp, the VDC warning light
may
illuminate. This is not a malfunction.
Restart the engine after driving onto a stable surface.
. If wheels or tires other than the INFINITI
recommended ones are used, the VDC
system may not operate properly and
the VDC warning light
may illumi-
nate.
. The VDC system is not a substitute for
winter tires or tire chains on a snow
covered road.
The Rear Active Steer system is an electro-
nically controlled four-wheel steering sys-
tem.
The angle of the rear wheels are adjusted
by the Rear Active Steer system, depending
on the vehicle speed and steering angle.
The rear wheels are designed to turn
momentarily in the opposite direction and
then change to the same direction as the
front wheels.
At low speeds, the rear wheels will not turn
and the system functions as a two-wheel
steering system.
If a malfunction occurs in the system, the
Rear Active Steer function will stop but the
ordinary two-wheel steering system will
operate normally. The “RAS”warning light
will illuminate. If the light illuminates while
driving, contact an INFINITI retailer for
repair.
WARNING
The Rear Active Steer system, although a
sophisticated device, cannot prevent acci-
dents resulting from careless or dangerous
driving techniques. Ultimately the responsi-
bility for safety of self and others rests in
the hands of the driver. Therefore only

SIC2574
Push the switch on to warn other drivers
when you must stop or park under
emergency conditions. All turn signal lights
will flash.
WARNING
.If stopping for an emergency, be sure to
move the vehicle well off the road.
. Do not use the hazard warning flashers
while moving on the highway unless
unusual circumstances force you to drive
so slowly that your vehicle might be-
come a hazard to other traffic. .
Turn signals do not work when the
hazard warning flasher lights are on.
The flasher can be actuated with the
ignition switch in any position.
Some state laws may prohibit the use of
the hazard warning flasher switch while
driving. In the event of a roadside emergency,
Roadside Assistance Service is available to
you. Please refer to your Warranty Informa-
tion Booklet (U.S.) or Warranty & Roadside
Assistance Information Booklet (Canada)
for details.
HAZARD WARNING FLASHER SWITCH
ROADSIDE ASSISTANCE PROGRAM

To shut off the engine in an emergency
situation while driving perform the follow-
ing procedure:
.Rapidly push the push-button ignition
switch 3 consecutive times in less than
1.5 seconds, or
. Push and hold the push-button ignition
switch for more than 2 seconds.TIRE PRESSURE MONITORING SYS-
TEM (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 appears on 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 re-
minders” (P.2-13),“Tire Pressure informa-
tion” (P.4-11) and “Tire Pressure
Monitoring System (TPMS)” (P.5-4).
WARNING
.If the low tire pressure warning light
illuminates or LOW PRESSURE informa-
tion is displayed 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 pressure 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 remain on after 1 minute.
Contact your INFINITI retailer as soon as
possible for tire replacement and/or
system resetting.
. Replacing tires with those not originally
specified by INFINITI could affect the
proper operation of the TPMS.

WARNING
Always follow the instructions below. Failure
to do so could result in damage to the
charging system and cause personal injury.
1. Remove the engine compartment cover,if necessary. See “Engine compartment
check locations ”(P.8-7).
2. If the booster battery is in another vehicle
*A, position the two vehicles
(
*Aand*B) to bring their batteries
into close proximity to each other.
Do not allow the two vehicles to touch.
3. Apply parking brake. Move the shift lever to the P (Park) position. Switch off
all unnecessary electrical systems
(light, heater, air conditioner, etc.).
4. Remove vent caps on the battery (if so equipped). Cover the battery with a
firmly wrung out moist cloth
*Cto
reduce explosion hazard.
5. Connect jumper cables in the sequence as illustrated (
*1?*2?*3?*4).

7-2Appearance and care
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
droppings, 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 dishwash-
ing liquid mixed with clean, lukewarm
(never hot) water.
CAUTION
. Do not use car washes that use acid in
the detergent. Some car washes, espe-
cially 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
household soap, strong chemical deter-
gents, gasoline or solvents.
. Do not wash the vehicle in direct sun-
light 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 foreign substances so the
paint surface is not scratched or da-
maged.
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.
WAXING
Regular waxing protects the paint surface
and helps retain new vehicle appearance.
Polishing is recommended to remove built-
up wax residue and to avoid a weathered
appearance before reapplying wax.
An INFINITI retailer can assist you in
choosing the proper product.
CLEANING EXTERIOR

7-4Appearance and care
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-
abrasive 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 dis-
coloration of the rubber. If a tire dressing is
applied to the tires, it may react with the
coating and form a compound. This com-
pound 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 diffi-
cult to remove). .
Wipe off excess tire dressing using a
dry towel. Make sure the tire dressing
is completely removed from the tire
tread/grooves.
. Allow the tire dressing to dry as
recommended by tire dressing manu-
facturer. Occasionally remove loose dust from the
interior 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
frequently.
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 check-
ing 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 5,000 miles (8,000 km).
Tires*: Check the pressure with a gauge
often and always prior to long distance
trips. If necessary, adjust the pressure in
all tires, including the spare, to the
pressure specified. Check carefully for
damage, cuts or excessive wear.
Tire Pressure Monitoring System (TPMS)
transmitter components: Replace the TPMS
transmitter grommet seal, valve core and
cap when the tires are replaced due to
wear or age.
Tire, wheel alignment and balance: If thevehicle 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 Book-
let.
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) mechan-
ism:
On a fairly steep hill, check that your
vehicle is held securely with the shift lever
in the P (Park) position without applying
any brakes.
Brake pedal: Check the pedal for smooth
operation. 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
operation regularly. The vehicle should be
securely held on a fairly steep hill with only
the parking brake applied. If the parking
brake needs adjusted, see an INFINITI
retailer.
Seat belts: Check that all parts of the seat
belt system (for example, buckles, an-
chors, adjuster and retractors) operate
properly and smoothly, and are installed
securely. Check the belt webbing for cuts,
fraying, wear or damage.
Seats: Check seat position controls such as
Maintenance and do-it-yourself8-3

8-4Maintenance and do-it-yourself
seat adjusters, seatback recliner, etc. to
ensure they operate smoothly and that all
latches lock securely in every position.
Check that the head restraints 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
steering conditions, such as excessive free
play, hard steering or strange noises.
Warning lights and chimes: Make sure that
all warning lights and chimes are operating
properly.
Windshield defroster: Check that the air
comes out of the defroster outlets properly
and in sufficient quantity when operating
the heater or air conditioner.
Windshield wiper and washer*: Check that
the wipers and washer operate properly
and that the wipers do not streak.
Under the hood and vehicle
The maintenance items listed here should
be checked periodically (for example, each
time you check the engine oil or refuel).
Battery*: Check the fluid level in each cell.
It should be between the MAX and MIN
lines. Vehicles operated in high tempera- tures or under severe condition require
frequent checks of the battery fluid level.
NOTE:
Care should be taken to avoid situations
that can lead to potential battery dis-
charge and potential no-start conditions
such as:
1.
Installation or extended use of electro-
nic accessories that consume battery
power when the engine is not running
(Phone chargers, GPS, DVD players,
etc.)
2. Vehicle is not driven regularly and/or
only driven short distances.
In these cases, the battery may need to be
charged to maintain battery health.
Brake fluid level*: Make sure that the
brake fluid level is between the MAX and
MIN lines on the reservoir.
Engine coolant level*: Check the coolant
level when the engine is cold.
Engine drive belts*: Make sure that no belt
is frayed, worn, cracked or oily.
Engine oil level*: Check the level after
parking the vehicle on a level spot and
turning off the engine. Wait more than 15
minutes for the oil to drain back into the oil pan.
Exhaust system:
Make sure there are no
loose supports, cracks or holes. If the
sound of the exhaust seems unusual or
there is a smell of exhaust fumes, im-
mediately have the exhaust system in-
spected by an INFINITI retailer. (See
“Precautions when starting and driving”
(P.5-3) section for exhaust gas (carbon
monoxide).)
Fluid leaks: Check under the vehicle for
fuel, oil, water or other fluid leaks after the
vehicle has been parked for a while. Water
dripping from the air conditioner after use
is normal. If you should notice any leaks or
if gasoline fumes are evident, check for the
cause and have it corrected immediately.
Power steering fluid level* and lines:
Check the level when the fluid is cold,
with the engine off. Check the lines for
proper attachment, leaks, cracks, etc.
Radiator and hoses: Check the front of the
radiator and clean off any dirt, insects,
leaves, etc., that may have accumulated.
Make sure the hoses have no cracks,
deformation, rot or loose connections.
Underbody: The underbody is frequently
exposed to corrosive substances such as
