traction control INFINITI QX30 2018 Owner's Manual

Stop the vehicle immediately, paying atten-
tion to road and traffic conditions, and switch
off the engine.
Secure the vehicle against rolling away.
Leave the vehicle and keep a safe distance
from the vehicle until the engine has cooled
down.
Check the coolant level and top up the cool-
ant, observing the warning notes (see "If your
vehicle overheats").
If you have to top up the coolant frequently,
have the engine cooling system checked.
Make sure that the air supply to the engine
radiator is not blocked, e. g. by frozen slush.
Do not start the engine again until the cool-
ant temperature is below 250°F (120°C). The
engine may otherwise be damaged.
Low fuel warning light
This light comes on when the fuel level in the
fuel tank is getting low. Refuel as soon as it is
convenient, preferably before the fuel gauge
reaches 0 (Empty).There will be a small re-
serve of fuel in the tank when the fuel gauge
reaches 0 (Empty).
Vehicle Dynamic Control
(VDC) warning light
The VDC warning light blinks when the Ve-
hicle Dynamic Control (VDC) system is oper-
ating, thus alerting the driver to the fact that
the road surface is slippery and the vehicle is
nearing its traction limits.
You may feel or hear the system working, this
is normal.
The light will continue to blink for a few sec-
onds after the VDC system stops limiting
wheel spin.
Cruise control or Intelligent Cruise Control is
deactivated.
For additional information see " Vehicle Dy-
namic Control (VDC) OFF indicator light " and
"Vehicle Dynamic Control (VDC) system".
INDICATOR LIGHTS
Turn signal/hazard indicator
lights
The appropriate light flashes when the turn
signal switch is activated. Both lights flash
when the hazard switch is turned on.
Low beam indicator light
This light comes on when the switch is turned
to the position:
The headlights will come
on and front side, tail, number plate and in-
strument lights remain on.
Vehicle Dynamic Control
(VDC) OFF indicator light
The light comes on when the Vehicle Dy-
namic Control (VDC) has been disabled. This
indicates that the VDC system is not operat-
ing.
Disabling the VDC system causes the For-
ward Emergency Braking system to become
unavailable. See " Forward emergency brak-
ing (FEB) system (if equipped)" for more de-
tails.
This light also comes on briefly when the
ignition switch is turned to the ON position.
The light will turn off after approximately
1 second if the VDC system is operational.
When the VDC OFF indicator light and VDC
warning light (see " Vehicle Dynamic Control
(VDC) warning light" later in this section)
come on with the VDC system turned on, it
alerts the driver to the fact that the system's
fail-safe mode is operating. This means that
the system may not be functioning properly.

tion, refer to "Flat tire".
DRINKING ALCOHOL/DRUGS
AND DRIVING
WARNING
Never drive under the influence of alcohol
or drugs. Alcohol in the bloodstream re-
duces coordination, delays reaction time
and impairs judgement. Driving after
drinking alcohol increases the likelihood of
being involved in an accident injuring your-
self and others. Additionally, if you are in-
jured in an accident, alcohol can increase
the severity of the injury.INFINITI is committed to safe driving. How-
ever, you must choose not to drive under the
influence of alcohol. Every year thousands of
people are injured or killed in alcohol-related
accidents. Although the local laws vary on
what is considered to be legally intoxicated,
the fact is that alcohol affects all people dif-
ferently and most people underestimate the
effects of alcohol.
Remember, drinking and driving don’t mix!
And that is true for drugs, too (over-the-
counter, prescription, and illegal drugs). Don’t
drive if your ability to operate your vehicle is
impaired by alcohol, drugs, or some other
physical condition.
DRIVING SAFETY PRECAUTIONS
Your INFINITI is designed for both normal
and off-road use. However, avoid driving in
deep water or mud as your INFINITI is mainly
designed for leisure use, unlike a conventional
off-road vehicle.
Remember that 2–wheel drive vehicles are
less capable than all-wheel drive (AWD)
models for rough road driving and extrication
when stuck in deep snow or mud, or the like.Please observe the following precautions:
WARNING
•Spinning the front wheels on slippery
surfaces may cause the AWD warning
message to display and the AWD system
to automatically switch from the AWD
to 2WD mode. This could reduce the
traction. Be especially careful when
towing a trailer. (AWD models)
•Drive carefully when off the road and
avoid dangerous areas. Every person
who drives or rides in this vehicle should
be seated with their seat belt fastened.
This will keep you and your passengers
in position when driving over rough ter-
rain.
•Do not drive across steep slopes. Instead
drive either straight up or straight down
the slopes. Off-road vehicles can tip
over sideways much more easily than
they can forward or backward.
•Many hills are too steep for any vehicle.
If you drive up them, you may stall. If you
drive down them, you may not be able to
control your speed. If you drive across
them, you may roll over.
5-10Starting and driving

Self-test feature
The ABS includes electronic sensors, electric
pumps, hydraulic solenoids and a computer.
The computer has a built-in diagnostic fea-
ture that tests the system each time you start
the engine and move the vehicle at a low
speed in forward or reverse. When the self-
test occurs, you may hear a “clunk” noise
and/or feel a pulsation in the brake pedal.
This is normal and does not indicate a mal-
function. If the computer senses a malfunc-
tion, it switches the ABS off and illuminates
the ABS warning light on the instrument
panel. The brake system then operates nor-
mally, but without anti-lock assistance. If the
ABS warning light illuminates during the
self-test or while driving, have the vehicle
checked. It is recommended you visit an
INFINITI retailer for this service.
Normal operation
The ABS operates at speeds above 3 to 6
MPH (5 to 10 km/h). The speed varies ac-
cording to road conditions.
When the ABS senses that one or more
wheels are close to locking up, the actuator
rapidly applies and releases hydraulic pres-
sure. This action is similar to pumping the
brakes very quickly. You may feel a pulsation
in the brake pedal and hear a noise from
under the hood or feel a vibration from the
actuator when it is operating. This is normal
and indicates that the ABS is operating prop-
erly. However, the pulsation may indicate
that road conditions are hazardous and extra
care is required while driving.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 wheel
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 function).
•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 conditions).
The VDC system can help the driver to main-
tain control of the vehicle, but it cannot pre-
vent loss of vehicle control in all driving situ-
ations.
VEHICLE DYNAMIC CONTROL (VDC)
SYSTEM
5-92Starting and driving

CAUTION
•When VDC is deactivated, the
VDC OFF warning light lights up con-
tinuously.
•If both thewarning light and
warning light are lit continuously, VDC
is not available due to a malfunction.
TRACTION CONTROL SYSTEM
(TCS)
The Traction Control System (TCS) is part of
VDC.
Traction control brakes the drive wheels indi-
vidually if they spin. This enables you to pull
away and accelerate on slippery surfaces, for
example if the road surface is slippery on one
side. In addition, more drive torque is trans-
ferred to the wheel or wheels with traction.
Traction control remains active if you deacti-
vate VDC.
CHARACTERISTICS OF VDC
If theVDC warning light goes out before
beginning the journey, VDC is automatically
active.If VDC intervenes, the
VDC warning
light flashes in the combination meter.
If VDC intervenes:
•Do not deactivate VDC under any circum-
stances.
•When pulling away, only depress the ac-
celerator pedal as far as is necessary.
•Adapt your driving style to suit the prevail-
ing road and weather conditions.
Deactivating/activating VDC
WARNING
If you deactivate VDC, VDC no longer
stabilizes the vehicle. There is an increased
risk of skidding and an accident.
Only deactivate VDC in the situations
described in the following section.
You can select between the following sta-
tuses of VDC:
•VDC is activated.
•VDC is deactivated.
It may be best to deactivate VDC in the fol-
lowing situations:
•When using snow chains.
•In deep snow.
•On sand or gravel.NOTE
Activate VDC as soon as the situations de-
scribed above no longer apply. VDC will oth-
erwise not be able to stabilize the vehicle if
the vehicle starts to skid or a wheel starts to
spin.
You can activate/deactivate VDC using the
vehicle information display. To activate/
deactivate VDC:
1. Start the engine
2. Press the
orbutton on the
steering wheel to select the [DriveAssist]
menu in the vehicle information display.
3. Press the
orbutton to select
VDC.
4. Press thebutton on the steering
wheel. The current selection is displayed.
5. To activate/deactivate: press the
button again.
VDC is deactivated if the
warning
light in the combination meter lights up
continuously when the engine is running.
Characteristics when VDC is deactivated:
If VDC is deactivated and one or more wheels
start to spin, the
VDC warning light
flashes in the combination meter. In such
situations, VDC will not stabilize the vehicle.
5-94Starting and driving

If you deactivate VDC:
•VDC no longer intervenes in understeer or
oversteer situations.
•Engine torque is no longer limited and the
drive wheels are able to spin.
The spinning of the wheels results in a
cutting action, so the tires cut through the
loose surface until the hit solid ground,
giving better traction.
•Traction control is still activated.
•VDC still provides support when you brake.
EBD (ELECTRONIC BRAKE
FORCE DISTRIBUTION)
EBD monitors and controls the brake pres-
sure on the rear wheels to help improve han-
dling during braking.
WARNING
If EBD is malfunctioning, the EBD [Inop-
erative See Operator's Manual] warning is
displayed in the vehicle information dis-
play. The
VDC warning light may also
light up.
If EBD is malfunctioning as a result of a
VDC malfunction, the rear wheels can lock,
e.g. under full braking. This increases the
risk of skidding and an accident.You should therefore adapt your driving
style to the different handling characteris-
tics. Have the brake system checked. It is
recommended you see an INFINITI retailer.
STEER CONTROL
STEER CONTROL helps you by transmitting
a noticeable steering force to the steering
wheel in the direction required for vehicle
stabilisation.
This steering support is provided in particular
if:
•Both right wheels or both left wheels are
on a wet or slippery road surface when
you brake.
•The vehicle starts to skid.
WARNING
No steering support is provided from
STEER CONTROL, if:
•VDC is malfunctioning.•The steering is faulty.
Power steering will, however, continue to
function.
WARNING
•Never rely solely on the Hill Start Assist
(HSA) system to prevent the vehicle
from moving backward on a hill. Always
drive carefully and attentively. Depress
the brake pedal when the vehicle is
stopped on a steep hill. Be especially
careful when stopped on a hill on frozen
or muddy roads. Failure to prevent the
vehicle from rolling backwards may re-
sult in a loss of control of the vehicle and
possible serious injury or death.
•The Hill Start Assist system is not de-
signed to hold the vehicle at a standstill
on a hill. Depress the brake pedal when
the vehicle is stopped on a steep hill.
Failure to do so may cause the vehicle to
roll backwards and may result in a colli-
sion or serious personal injury.
•The Hill Start Assist system may not
prevent the vehicle from rolling back-
wards on a hill under all load or road
conditions. Always be prepared to de-
press the brake pedal to prevent the
vehicle from rolling backwards. Failure
to do so may result in a collision or seri-
ous personal injury.
HILL START ASSIST (HSA)

3. Tire chains may be used if desired. Make
sure they are the proper size for the tires
on your vehicle and are installed according
to the chain manufacturer’s instructions.
Use chain tensioners when recommended
by the tire chain manufacturer to ensure a
tight fit. Loose end links of the tire chains
must be secured or removed to prevent
the possibility of whipping action damage
to the fenders or underbody. In addition,
drive at a reduced speed, otherwise, your
vehicle may be damaged and/or vehicle
handling and performance may be ad-
versely affected.
SPECIAL WINTER EQUIPMENT
It is recommended that the following items
be carried in the vehicle during the winter:
•A scraper and stiff-bristled brush to re-
move ice and snow from the windows.
•A sturdy, flat board to be placed under the
jack to give it firm support.
•A shovel to dig the vehicle out of snow-
drifts.
•Extra washer fluid to refill the windshield
washer fluid reservoir.
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 reaching it. Try
not to brake while on the ice, and avoid
any sudden steering maneuvers.
•Do not use cruise control on slippery
roads.
•Snow can trap dangerous exhaust gas
under your vehicle. Keep snow clear of
the exhaust pipe and from around your
vehicle.

name molding that is higher or deeper than
the same molding on the other sidewall of the
tire, or (2) the outward facing sidewall of an
asymmetrical tire that has a particular side
that must always face outward when
mounted on a vehicle.
TYPES OF TIRES
WARNING
•When changing or replacing tires, be
sure all four tires are of the same type
(i.e, summer, all season or snow) and
construction. An INFINITI retailer may
be able to help you with information
about tire type, size, speed rating and
availability.
•Replacement tires may have a lower
speed rating than the factory equipped
tires, and they may not match the po-
tential maximum vehicle speed. Never
exceed the maximum speed rating of the
tire.
•Always use tires of the same type, size,
brand, construction and tread pattern
on all four wheels. Failure to do so may
result in a circumference difference be-
tween tires on the front and rear axles
which can cause the Vehicle Dynamic
Control (VDC) system to malfunctionresulting in personal injury or death, ex-
cessive tire wear and may damage the
transmission, transfer case and differ-
ential gears.
•For additional information regarding
tires, refer to “Important Tire Safety In-
formation” (US) or “Tire Safety Infor-
mation“ (Canada) in the Warranty In-
formation Booklet.
CAUTION
ONLY use spare tires specified for the
model.
If excessive tire wear is found, it is recom-
mended that all four tires be replaced with
tires of the same size, brand, construction
and tread pattern. The tire pressure and
wheel alignment should also be checked and
corrected as necessary. It is recommended
that you visit an INFINITI retailer for this
service.
All season tires
INFINITI specifies all season tires on some
models to provide good performance all year,
including snowy and icy road conditions. All
season tires are identified by ALL SEASON
and/or M&S on the tire sidewall. Snow tires
have better snow traction than all seasontires and may be more appropriate in some
areas.
Summer tires
INFINITI specifies summer tires on some
models to provide superior performance on
dry roads. Summer tire performance is sub-
stantially reduced in snow and ice. Summer
tires do not have the tire traction rating M&S
on the tire sidewall.
If you plan to operate your vehicle in snowy or
icy conditions, INFINITI recommends the use
of snow or all season tires on all four wheels.
Snow tires
If snow tires are needed, it is necessary to
select tires equivalent in size and load rating
to the original equipment tires. If you do not,
it can adversely affect the safety and han-
dling of your vehicle.
Generally, snow tires have lower speed rat-
ings than factory equipped tires and may not
match the potential maximum vehicle speed.
Never exceed the maximum speed rating of
the tire. If you install snow tires, they must be
the same size, brand, construction and tread
pattern on all four wheels.
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
