2017 INFINITI QX30 overheating

RADAR MAINTENANCE
The two radar sensor unitsAfor the BSW
system are located near the rear bumper. Al-
ways keep the area near the radar sensors
clean.
The radar sensors may be blocked by temporary
ambient conditions such as splashing water,
mist or fog.
The blocked condition may also be caused by
objects such as ice, frost or dirt obstructing the
radar sensors.
Check for and remove objects obstructing the
area around the radar sensors.
Do not attach stickers (including transparent
material), install accessories or apply addi-
tional paint near the radar sensors. Do not strike or damage the area around the
radar sensors. It is recommended you consult
an INFINITI retailer if the area around the radar
sensors is damaged due to a collision.

Cruise control maintains a constant road speed
for you. It brakes automatically in order to avoid
exceeding the set speed. You must select a
lower gear in good time on long and steep
downhill gradients, especially if the vehicle is
laden or towing a trailer.WARNING
For vehicles with automatic transmission, you
need to have selected manual drive program M
(see
Manual drive program earlier in this sec-
tion). By doing so, you will make use of the
braking effect of the engine. This relieves the
load on the brake system and prevents the
brakes from overheating and wearing too
quickly.
Use cruise control only if road and traffic con-
ditions are appropriate for maintaining a steady
speed for a prolonged period. You can set the
cruise control at any road speed above 20 MPH
(30 km/h).
The speed indicated in the speedometer may
differ slightly from the set speed.

slight pulsation. This is normal and indicates
that the Brake Assist System is operating (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 brakesreturn to normal. Avoid driving the vehicle at
high speeds until the brakes function 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 position,
release the parking brake while depressing the
accelerator pedal. If your vehicle has an electric
parking brake, this will automatically release
when you depress the accelerator pedal (DCT
models).
Driving downhill
The engine braking action is effective for con-
trolling the vehicle while descending hills.
A low gear position in the manual shift mode,
low enough to obtain sufficient engine braking,
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 so-
phisticated device, but it cannot prevent acci-
dents resulting from careless or dangerous
driving techniques. It can help maintain ve-
hicle control during braking on slippery sur-
faces. Remember that stopping distances on
slippery surfaces will be longer than on normal
surfaces even with ABS. Stopping distances
may also be longer on rough, gravel or snow
covered roads, or if you are using tire chains.
Always 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 information label. (See
5-88Starting and driving

WARNING
•Do not continue to drive if your vehicle over-
heats. Doing so could cause engine damage
or a vehicle fire.
•To avoid the danger of being scalded, never
remove the radiator or coolant reservoir cap
while the engine is hot. When the radiator or
coolant reservoir cap is removed, pressur-
ized hot water will spurt out, possibly caus-
ing serious injury.
•Do not open the hood if steam is coming out.
If the engine of your vehicle is overheating
(indicated by the engine coolant temperature
gauge) or if you feel a lack of engine power,
detect unusual noise, etc., proceed as follows:
1. Move and park the vehicle safely off the road and away from traffic.
2. Turn on the hazard warning flasher lights.
3. Apply the parking brake.
4. Press the P (Park) button. DO NOT STOP THE ENGINE.
5. Open all windows. 6. Switch off the air conditioner system (if
equipped).
7. Set the heater or air conditioner temperature control to maximum “HOT” and fan speed
control to maximum speed.
8. Exit the vehicle.
9. Visually inspect and listen for steam or coolant escaping from the radiator before
opening the hood.WARNING
If steam or water is coming from the engine,
stand clear to prevent getting burned.
10. Open the hood. For details, see Hoodin
the 3. Pre-driving checks and adjustments
section.
11. Visually check if the cooling fan is running.
12. Visually check the radiator and radiator hoses for leakage.
WARNING
Be careful not to allow your hands, hair, jew-
elry or clothing to come into contact with, or
get caught in, engine belts or the engine cool-
ing fan. The engine cooling fan can start at any
time.
13. After the engine cools down, check the coolant level in the engine coolant reservoir
with the engine running. Do not open the
radiator cap (if equipped).
14. If the level is low, remove the engine cool- ant reservoir cap and add coolant slowly
into the reservoir. After refilling the reser-
voir to the MAX level, install the reservoir
cap.
15. Close the hood.
Have your vehicle inspected or repaired. It is
recommended you visit an INFINITI retailer.
IF YOUR VEHICLE OVERHEATS
In case of emergency6-13

•When adding or replacing coolant, be sure
to use only INFINITI Genuine Engine Cool-
ant, BASF Glysantin G40 or equivalent in its
quality. The use of other types of engine
coolant may damage the engine cooling
system.
CHECKING ENGINE COOLANT LEVEL
NOTE
The coolant level must only be checked and cor-
rected when the engine is cold.
1. Park the vehicle on a level surface.Only check the coolant level if the vehicle is
on a level surface and the engine is cold.
2. Slowly turn cap
1half a turn counter-
clockwise to allow excess pressure to es-
cape.
3. Turn cap
1further counter-clockwise and
remove it.
If the coolant is at the level of marker bar
3in the filler neck when cold, there is enough
coolant in coolant expansion tank
2. 4. If necessary, top up with INFINITI Genuine
Engine Coolant, BASF Glysantin G40 or
equivalent in its quality.
5. Replace cap
1and turn it clockwise as far
as it will go.
If the cooling system frequently requires cool-
ant, have it checked. It is recommended that you
visit an INFINITI retailer for this service.
CHANGING ENGINE COOLANT
An INFINITI retailer can change the engine
coolant.
Improper servicing can result in reduced heater
performance and engine overheating.

level roads, it is recommended you have an
INFINITI retailer correct the condition. Failure to
correct the condition is misuse of the vehicle, for
which INFINITI is not responsible.
Incorrect ignition timing will result in knocking,
after-run and/or overheating. This in turn may
cause excessive fuel consumption or damage to
the engine. If any of the above symptoms are
encountered, have your vehicle checked. It is
recommended you visit an INFINITI retailer.
However, now and then you may notice light
spark knock for a short time while accelerating
or driving up hills. This is no cause for concern,
because you get the greatest fuel benefit when
there is light spark knock for a short time under
heavy engine load.

ENGINE OIL AND OIL FILTER
RECOMMENDATIONS
Selecting the correct oil
It is essential to choose the correct grade,
quality, and viscosity engine oil to ensure sat-
isfactory engine life and performance. For addi-
tional information, refer toRecommended
fluids/lubricants and capacities earlier in this
section. INFINITI recommends the use of an
energy conserving oil in order to improve fuel
economy.
Select only engine oils that meet the American
Petroleum Institute (API) certification or Interna-
tional Lubricant Standardization and Approval Committee (ILSAC) certification and SAE viscos-
ity standard. These oils have the API certifica-
tion mark on the front of the container. Oils
which do not have the specified quality label
should not be used as they could cause engine
damage.
Oil additives
INFINITI does not recommend the use of oil
additives. The use of an oil additive is not
necessary when the proper oil type is used and
maintenance intervals are followed.
Oil which may contain foreign matter or has
been previously used should not be used.
Oil viscosity
The engine oil viscosity or thickness changes
with temperature. Because of this, it is impor-
tant that the engine oil viscosity be selected
based on the temperatures at which the vehicle
will be operated before the next oil change.
Choosing an oil viscosity other than that recom-
mended could cause serious engine damage.
Selecting the correct oil filter
Your new vehicle is equipped with a high—
quality genuine INFINITI oil filter. When replac-
ing, it is recommended you use the genuine oil
filter or its equivalent for the reason described
in “Change intervals”.
