stop start INFINITI QX30 2019 Repair Manual

CAUTION
Never tow the vehicle with one axle raised.
This may damage the differential. Damage
of this sort is not covered by the warranty.
All wheels must be fully raised (see "Four-
Wheel Drive (4WD) models")
4WD, together with VDC, improves the trac-
tion of your vehicle whenever a drive wheel
spins due to insufficient grip.
If you fail to adapt your driving style, 4WD
can neither reduce the risk of an accident nor
override the laws of physics. 4WD cannot
take account of road, weather, and traffic
conditions. 4WD is only an aid. You are re-
sponsible for the distance to the vehicle in
front, for vehicle speed, for braking in good
time, and for staying in lane.
If a drive wheel spins due to insufficient grip
•When pulling away, only depress the ac-
celerator pedal as far as is necessary.
•Accelerate less when driving.
NOTE
In wintry driving conditions, the maximum
effectiveness of 4WD can only be achieved if
you use winter tires (M+S tires), with snow
chains if necessary.
WARNING
•Do not stop or park the vehicle over
flammable materials such as dry grass,
waste paper or rags. They may ignite
and cause a fire.
•Safe parking procedures require that
both the parking brake be applied and
the P (Park) position engaged. Failure to
do so could cause the vehicle to move
unexpectedly or roll away and result in
an accident.
•When parking the vehicle, make sure the
P (Park) position is engaged. The shift
lever cannot be moved out of the P
(Park) position without depressing the
brake pedal.
•Never leave the engine running while the
vehicle is unattended.
•Do not leave children unattended inside
the vehicle. They could unknowingly ac-
tivate switches or controls or move the
vehicle. Unattended children could be-
come involved in serious accidents.
•To help avoid risk of injury or death
through unintended operation of the
vehicle and/or its systems, do not leave
children, people who require the assis-
tance of others, or pets unattended in
your vehicle. Additionally, the tempera-
ture inside a closed vehicle on a warm
day can quickly become high enough to
cause a significant risk of injury or death
to people and pets.
CAUTION
Always secure the vehicle correctly against
rolling away. Otherwise, the vehicle or its
drive train could be damaged.
To ensure that the vehicle is secured against
rolling away unintentionally:
•The electric parking brake must be applied.
•The transmission must be in position P
(Park) and the transmission position dis-
play must show P in the vehicle informa-
tion display.
•The key must be removed from the ignition
switch.
•On uphill or downhill gradients, the front
wheels must be turned towards the curb.
PARKING
Starting and driving5-87

•Do not place the ignition switch in the on
position while the steering wheel or a
tire is removed.
•Do not turn the steering wheel as much
as possible while the ignition switch is in
any position other than the ON position.
•Installing an accessory on the steering
wheel, or changing the steering wheel,
may reduce the steering performance.
NOTE
When the steering wheel is operated repeat-
edly or continuously while parking or driving
at a very low speed, the power assistance for
the steering wheel will be reduced. This is to
prevent overheating of the electric power
steering system and protect it from becom-
ing damaged. While the power assistance is
reduced, steering wheel operation will be-
come heavy. When the temperature of the
electric power steering system decreases,
the power assistance level will return to nor-
mal. Avoid repeating such steering wheel
operations that could cause the electric
power steering system to overheat.The brake system has two separate hydraulic
circuits. If one circuit malfunctions, you will
still have braking ability at two wheels.
BRAKE PRECAUTIONS
WARNING
While driving on a slippery surface, be
careful when braking, accelerating or
downshifting. Abrupt braking or acceler-
ating could cause the wheels to skid and
result in an accident.
Vacuum assisted brakes
The brake booster aids braking by using en-
gine vacuum. If the engine stops, you can
stop the vehicle by depressing the brake
pedal. However, greater foot pressure on the
brake pedal will be required to stop the ve-
hicle. The stopping distance will be longer.
WARNING
•If the engine is not running or is turned
off while driving, the power assist for
the brakes will not work. Braking will be
harder.
•Do not coast with the engine stopped.When the brake pedal is depressed slowly
and firmly, you may hear a clicking noise and
feel a slight pulsation. This is normal and
indicates that the Brake Assist System is op-
erating (if equipped).
Using brakes
Avoid resting your foot on the brake pedal
while driving. This will overheat the brakes,
wear out the brake linings/pads faster, and
increase fuel consumption.
To help reduce brake wear and to prevent the
brakes from overheating, reduce speed and
downshift to a lower gear before going down
a slope or long grade. Overheated brakes
may reduce braking performance and could
result in loss of vehicle control.
While driving on a slippery surface, be careful
when braking, accelerating or downshifting.
Abrupt braking or acceleration could cause
the wheels to skid and result in an accident.
Wet brakes
When the vehicle is washed or driven through
water, the brakes may get wet. As a result,
your braking distance will be longer and the
vehicle may pull to one side during braking.
To dry the brakes, drive the vehicle at a safe
speed while lightly depressing the brake
pedal to heat up the brakes. Do this until the
BRAKE SYSTEM
5-90Starting and driving

brakes return to normal. Avoid driving the
vehicle at high speeds until the brakes func-
tion correctly.
Driving uphill
When starting on a steep gradient, it is some-
times difficult to operate the brake. Use the
parking brake to hold the vehicle. When ready
to start, make sure that the shift lever is in an
appropriate forward or reverse driving posi-
tion, release the parking brake while depress-
ing the accelerator pedal. If your vehicle has
an electric parking brake, this will automati-
cally release when you depress the accelera-
tor pedal (DCT models).
Driving downhill
The engine braking action is effective for
controlling the vehicle while descending hills.
A low gear position in the manual shift mode,
low enough to obtain sufficient engine brak-
ing, should be selected.
Parking brake break-in
Break in the parking brake shoes whenever the
stopping effect of the parking brake is weak-
ened or whenever the parking brake shoes
and/or drums/rotors are replaced, in order to
assure the best braking performance.
This procedure is described in the vehicle ser-
vice manual and can be performed by an
INFINITI retailer.
ANTI-LOCK BRAKING SYSTEM
(ABS)
WARNING
The Anti-lock Braking System (ABS) is a
sophisticated device, but it cannot prevent
accidents resulting from careless or dan-
gerous driving techniques. It can help
maintain vehicle control during braking on
slippery surfaces. Remember that stopping
distances on slippery surfaces will be lon-
ger than on normal surfaces even with
ABS. Stopping distances may also be lon-
ger on rough, gravel or snow covered
roads, or if you are using tire chains. Al-
ways maintain a safe distance from the ve-
hicle in front of you. Ultimately, the driver
is responsible for safety.
Tire type and condition may also affect
braking effectiveness.
–When replacing tires, install the specified
size of tires on all four wheels.–When installing a replacement tire, make
sure that it is the proper size and type as
specified on the tire and loading informa-
tion label. (See "Wheels and Tires".)
–For detailed information, see "Wheels and
tires".
The Anti-lock Braking System (ABS) controls
the brakes so the wheels do not lock during
hard braking or when braking on slippery sur-
faces. The system detects the rotation speed
at each wheel and varies the brake fluid pres-
sure to prevent each wheel from locking and
sliding. By preventing each wheel from lock-
ing, the system helps the driver maintain
steering control and helps to minimize swerv-
ing and spinning on slippery surfaces.
Using system
Depress the brake pedal and hold it down.
Depress the brake pedal with firm steady pres-
sure, but do not pump the brakes. The ABS will
operate to prevent the wheels from locking up.
Steer the vehicle to avoid obstacles.
WARNING
Do not pump the brake pedal. Doing so may
result in increased stopping distances.
Starting and driving5-91

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.

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.

In addition to the vehicle load, the driving
distance possible depends upon:
•Vehicle speed.
•Road condition.
•Outside temperature.
The driving distance possible in run-flat mode
may be reduced by extreme driving
conditions/maneuvers, or it can be increased
through a moderate style of driving.
The driving distance possible in run-flat mode
is counted from the moment the tire pressure
loss warning appears in the vehicle informa-
tion display.
You must not exceed a maximum speed of
50 MPH (80 km/h).
When replacing one or all tires, observe the
following specifications for your vehicle's tires:
•Size
•Type
•Run-flat mark
If a tire has gone flat and cannot be replaced
with a run flat tire, a standard tire may be
used as a temporary measure. Make sure that
you use the proper size and type (summer or
winter tire).
WARNING
Do not exceed the stated maximum speed.
Avoid abrupt steering and driving maneu-
vers, and driving over obstacles (curbs, pot
holes, off road). This applies in particular to
a laden vehicle.
Stop driving in emergency mode if:
•You hear banging noises.
•The vehicle starts to shake.
•You see smoke and smell rubber.
•VDC is intervening constantly.
•There are tears in the sidewalls of the
tire.
After driving in emergency mode, have the
wheel rims checked with regard to their
further use. It is recommended you visit an
INFINITI retailer for this service. The faulty
tire must be replaced.
REMOVING AND FITTING
