brakes NISSAN QASHQAI 2018 Owner´s Manual

5-108Starting and driving
tion, it switches the ABS off and illumi-
nates the ABS warning light on the
instrument panel. The brake system then
operates normally, 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 a NISSAN dealer for this service.
Normal operation
The ABS operates at speeds above 3 to 6
MPH (5 to 10 km/h). The speed varies
according to road conditions.
When the ABS senses that one or more
wheels are close to locking up, the
actuator rapidly applies and releases
hydraulic pressure. 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 properly. How-
ever, the pulsation may indicate that road
conditions are hazardous and extra care
is required while driving.The Vehicle Dynamic Control (VDC) sys-
tem uses various sensors to monitor
driver inputs and vehicle motion. Under
certain driving conditions, the VDC sys-
tem helps to perform the following func-
tions.
.
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 con-
trol 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 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 help 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.
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.2-15) and “Vehicle Dynamic
Control (VDC) off indicator light” (P.2-17).
VEHICLE DYNAMIC CONTROL (VDC) SYSTEM

WARNING
.Never rely solely on the hill start
assist system to prevent the ve-
hicle 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 care-
ful when stopped on a hill on
frozen or muddy roads. Failure
to prevent the vehicle from rolling
backwards may result in a loss of
control of the vehicle and possi-
ble serious injury or death.
. The hill start assist system is not
designed 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 collision or serious personal
injury.
. The hill start assist system may
not prevent the vehicle from roll-
ing backwards on a hill under all
load or road conditions. Always
be prepared to depress the brake
pedal to prevent the vehicle from
rolling backwards. Failure to do so may result in a collision or
serious personal injury.
The hill start assist system automatically
keeps the brakes applied to help prevent
the vehicle from rolling backwards in the
time it takes the driver to release the
brake pedal and apply the accelerator
when the vehicle is stopped on a hill.
The hill start assist system will operate
automatically under the following condi-
tions:
. The transmission is shifted to a for-
ward or reverse gear.
. The vehicle is stopped completely on a
hill by applying the brake.
The maximum holding time is 2 seconds.
After 2 seconds the vehicle will begin to
roll back and the hill start assist system
will stop operating completely.
The hill start assist system will not
operate when the transmission is shifted
to the N (Neutral) or P (Park) position (CVT
models) or on a flat and level road.
When the Vehicle Dynamic Control (VDC)
warning light illuminates in the meter, the
hill start assist system will not operate.
(See “Vehicle Dynamic Control (VDC)
warning light” (P.2-15).)
FREEING A FROZEN DOOR LOCK
To prevent a door lock from freezing,
apply deicer through the key hole. If the
lock becomes frozen, heat the key before
inserting it into the key hole, or use the
Intelligent Key system or the remote
keyless entry key fob.
ANTI-FREEZE
In the winter when it is anticipated that
the outside temperature will drop below
32°F (0°C), check the anti-freeze to assure
proper winter protection. For additional
information, see “Engine cooling system”
(P.8-4).
BATTERY
If the battery is not fully charged during
extremely cold weather conditions, the
battery fluid may freeze and damage the
battery. To maintain maximum efficiency,
the battery should be checked regularly.
For additional information, see “Battery”
(P.8-11).
DRAINING OF COOLANT WATER
If the vehicle is to be left outside without
anti-freeze, drain the cooling system,
including the engine block. Refill before
operating the vehicle. For details, see
“Engine cooling system” (P.8-4).

Be careful not to clog the washer nozzle. This may cause improper windshield
washer operation. If the nozzle is clogged,
remove any objects with a needle or small
pin
. Be careful not to damage the
nozzle. It is recommended you contact a NISSAN
dealer if checking or replacement is
required.
If the brakes do not operate properly, it is
recommended you have the brakes
checked by a NISSAN dealer.
SELF-ADJUSTING BRAKES
Your vehicle is equipped with self-adjust-
ing brakes.
The disc-type brakes self-adjust every
time the brake pedal is applied.
WARNING
Have your brake system checked if
the brake pedal height does not
return to normal. It is recommended
you visit a NISSAN dealer for this
service.
BRAKE PAD WEAR WARNING
The disc brake pads have audible wear
warnings. When a brake pad requires
replacement, it will make a high pitched
scraping sound when the vehicle is in
motion. This scraping sound will first
occur only when the brake pedal is
depressed. After more wear of the brake
pad, the sound will always be heard even
if the brake pedal is not depressed. Have
the brakes checked as soon as possible if
the wear warning sound is heard.
Under some driving or climate conditions,

other corrosive materials, check lubrica-
tion 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
checking 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.
Wheel alignment and balance: If the
vehicle 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 Informa-
tion” (US) or “Tire Safety Information”
(Canada) in the NISSAN Warranty Infor-
mation Booklet.
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 scheduled mainte-
nance, 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.
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, have your vehicle checked immediately. It is recommended you visit
a NISSAN dealer for this service. Keep the
floor mat away from the pedal.
Brakes:
Check that the brakes do not pull
the vehicle to one side when applied.
Continuously Variable Transmission
(CVT) P (Park) mechanism: On a fairly
steep hill, check that the vehicle is held
securely with the shift lever in the P (Park)
position without applying any brakes.
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, it is re-
commended you visit a NISSAN dealer for
this service.
Seat belts: Check that all parts of the seat
belt system (for example, buckles, an-
chors, adjusters 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 seat adjusters, seatback recliners, 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.
