2018 INFINITI QX30 Engine install

•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

•After a short time, hill start assist will no
longer brake your vehicle and it could
roll away There is a risk of an accident
and injury. Therefore, quickly move your
foot from the brake pedal to the accel-
erator pedal. Never leave the vehicle
when it is held by hill start assist.
Hill start assist helps you when pulling away
forwards or in reverse on an uphill gradient. It
holds the vehicle for a short time after you
have removed your foot from the brake
pedal. This gives you enough time to move
your foot from the brake pedal to the accel-
erator pedal and depress it before the vehicle
begins to roll.
Hill start assist is not active if
•You are pulling away on a level road or a
downhill gradient.
•On vehicles with automatic transmission,
the transmission is in position N.
•The electric parking brake is applied.
•VDC is malfunctioning.
FREEING A FROZEN DOOR LOCK
To prevent a door lock from freezing, apply
deicer through the key hole. If the lock be-
comes frozen, heat the key before inserting it
into the key hole, or use the INFINITI Intelli-
gent Key.
ANTIFREEZE
In the winter when it is anticipated that the
temperature will drop below 32°F (0°C),
check the antifreeze to assure proper winter
protection. For additional information, see
"Engine cooling system".
BATTERY
If the battery is not fully charged during ex-
tremely cold weather conditions, the battery
fluid may freeze and damage the battery. To
maintain maximum efficiency, the battery
should be checked regularly. For details, see
"Battery" of this manual.
DRAINING OF ENGINE COOLANT
If the vehicle is to be left outside without
antifreeze, drain the cooling system, including
the engine block. Refill before operating the
vehicle. For details, see "Changing engine
coolant" of this manual.
TIRE EQUIPMENT
1. SUMMER tires have a tread designed to
provide superior performance on dry
pavement. However, the performance of
these tires will be substantially reduced in
snowy and icy conditions. If you operate
your vehicle on snowy or icy roads,
INFINITI recommends the use of MUD &
SNOW or ALL SEASON TIRES on all four
wheels. It is recommended that you visit
an INFINITI retailer for the tire type, size,
speed rating and availability information.
2. For additional traction on icy roads, stud-
ded tires may be used. However, some
U.S. states and Canadian provinces pro-
hibit their use. Check local, state and pro-
vincial 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.
