2019 INFINITI QX50 ESP

The chassis control is an electric control mod-
ule that includes the following functions:∙ Active Trace Control
∙ Active Engine Brake
∙ Active Ride Control
ACTIVE TRACE CONTROL
This system senses driving based on the driv-
er’s steering and acceleration/braking pat-
terns, and controls brake pressure at indi-
vidual wheels to help smooth vehicle
response.
When the lower display is used to turn off the
VDC system, the Active Trace Control sys-
tem is also turned off.
If the Active Trace Control is not functioning
properly, the FEB with Pedestrian Detection
system warning indicator light illuminates in
the instrument panel.
The Active Trace Control can be set to on
(enabled) or off (disabled) through the lower
display “Infiniti Drive Mode Selector” menu
option.
ACTIVE ENGINE BRAKE
The Active Engine Brake function adds subtle
deceleration by controlling Continuously
Variable Transmission (CVT) gear ratio, de-
pending on the cornering condition calcu-
lated from the driver’s steering input and plu-
ral sensors. This benefit is for easier
traceability and less workload of adjusting
speed with braking at corners.
The Active Engine Brake also enhances brak-
ing feel by adding subtle deceleration with
CVT gear ratio control according to the driv-
er’s brake pedal operation
The Active Engine Brake can be set to on
(enabled) or off (disabled) through the lower
display “Infiniti Drive Mode Selector” menu
option.

WARNING
∙ Never rely solely on the hill start assistsystem to prevent the vehicle from mov-
ing backward on a hill. Always drive care-
fully 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 result 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. Fail-
ure 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 pre- vent the vehicle from rolling 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. When the vehicle is stopped on a hill, the hill
start assist system automatically keeps the
brakes applied to help prevent the vehicle
from rolling backward in the time it takes the
driver to release the brake pedal and apply
the accelerator.
The hill start assist system will operate auto-
matically under the following conditions:
∙ The transmission is shifted to a forward or reverse gear.
∙ The vehicle is stopped completely on a hill by applying the brake. The maximum
holding time is 2 seconds. After 2 sec-
onds the vehicle will begin to roll back and
the hill start assist system will stop oper-
ating completely.
The hill start assist system will not operate
when the shift lever is placed in the N (Neu-
tral), the Park button is pressed to place the
vehicle in the P (Park) position or on a flat and
level road. The sonar system sounds a tone to inform the
driver of obstacles near the bumper.
When the sonar system is turned on, the
sonar view will automatically appear in the
center display when the camera is activated.
WARNING
Failure to follow the warnings and instruc-
tions for proper use of the sonar system
could result in serious injury or death.
∙ The sonar system is not a replacement for
proper driving procedures and is not de-
signed to prevent contact with vehicles
or objects.

∙ The driver is always responsible forsafety during parking and other maneu-
vers. Always look around and check that
it is safe to do so before parking.
∙ This function is designed as an aid to the driver in detecting large stationary ob-
jects to help avoid damaging the vehicle.
If your vehicle sustains damage to the bum-
per fascia, leaving it misaligned or bent, the
sensing zone may be altered causing inaccu-
rate measurement of obstacles or false
alarm.
CAUTION
∙ Excessive noise (such as audio system volume or an open vehicle window) will
interfere with the tone and it may not be
heard.
∙ Keep the sonar sensors (located on the bumper fascias) free from snow, ice and
large accumulations of dirt. Do not clean
the sensors with sharp objects. If the sen-
sors are covered, the accuracy of the so-
nar function will be diminished.
SYSTEM OPERATION
The system informs with a visual and audible
signal of front obstacles when the shift lever
is in the D (Drive) position and both front and
rear obstacles when the shift lever is in the R
(Reverse) position.

The system is deactivated at speeds above
6 mph (10 km/h). It is reactivated at lower
speeds.
The intermittent tone will stop after 3 sec-
onds when an obstacle is detected by only
the corner sensor and the distance does not
change. The tone will stop when the obstacle
get away from the vehicle. When the object is detected, the indicator
(green) appears and blinks and the tone
sounds intermittently. When the vehicle
moves closer to the object, the color of the
indicator turns yellow and the rate of the
blinking increases. When the vehicle is very
close to the object, the indicator stops blink-
ing and turns red, and the tone sounds con-
tinuously.

In order to maintain the appearance of your
vehicle, it is important to take proper care of
it.
To protect the paint surfaces, wash your ve-
hicle as soon as you can:∙ After a rainfall to prevent possible dam- age from acid rain.
∙ After driving on coastal roads.
∙ When contaminants such as soot, bird droppings, tree sap, metal particles or
bugs get on the paint surface.
∙ When dust or mud builds up on the sur- face.
Whenever possible, store or park your vehicle
inside a garage or in a covered area.
When it is necessary to park outside, park in a
shady area or protect the vehicle with a body
cover.
Be careful not to scratch the paint surface
when putting on or removing the body cover.WASHING
Wash dirt off with a wet sponge and plenty
of water. Clean the vehicle thoroughly using a
mild soap, a special vehicle soap or general
purpose dishwashing liquid mixed with clean,
lukewarm (never hot) water.
CAUTION
∙ Do not use car washes that use acid in the detergent. Some car washes, especially
brushless ones, use some acid for clean-
ing. The acid may react with some plastic
vehicle components, causing them to
crack. This could affect their appearance,
and also could cause them not to function
properly. Always check with your car
wash to confirm that acid is not used.
∙ Do not wash the vehicle with strong household soap, strong chemical deter-
gents, gasoline or solvents.
∙ Do not wash the vehicle in direct sunlight or while the vehicle body is hot, as the
surface may become water-spotted.
∙ Avoid using tight-napped or rough cloths, such as washing mitts. Care must
be taken when removing caked-on dirt or
other foreign substances so the paint
surface is not scratched or damaged. Rinse the vehicle thoroughly with plenty of
clean water.
Inside edges, seams and folds on the doors,
hatches and hood are particularly vulnerable
to the effects of road salt. Therefore, these
areas must be cleaned regularly. Take care
that the drain holes in the lower edge of the
door are open. Spray water under the body
and in the wheel wells to loosen the dirt and
wash away road salt.
A damp chamois can be used to dry the ve-
hicle to avoid water spots.
WAXING
Regular waxing protects the paint surface
and helps retain new vehicle appearance.
Polishing is recommended to remove built-up
wax residue and to avoid a weathered ap-
pearance before re-applying wax.
An INFINITI retailer can assist you in choos-
ing the proper product.
∙ Wax your vehicle only after a thorough washing. Follow the instructions supplied
with the wax.
∙ Do not use a wax containing any abra- sives, cutting compounds or cleaners that
may damage the vehicle finish.
CLEANING EXTERIOR
7-2Appearance and care

Machine compounding or aggressive polish-
ing on a base coat/clear coat paint finish may
dull the finish or leave swirl marks.
REMOVING SPOTS
Remove tar and oil spots, industrial dust, in-
sects, and tree sap as quickly as possible from
the surface of the paint to avoid lasting dam-
age or staining. Special cleaning products are
available at an INFINITI retailer or any auto-
motive accessory store. It is recommended
that you visit an INFINITI retailer for these
products.
UNDERBODY
In areas where road salt is used in winter, it is
necessary to clean the underbody regularly in
order to prevent dirt and salt from building up
and causing the acceleration of corrosion on
the underbody and suspension. Before the
winter period and again in the spring, the
underseal must be checked and, if necessary,
re-treated.
GLASS
Use glass cleaner to remove smoke and dust
film from the glass surfaces. It is normal for
glass to become coated with a film after the
vehicle is parked in the hot sun. Glass cleaner
and a soft cloth will easily remove this film.
CAUTION
When cleaning the inside of the windows,
do not use sharp-edged tools, abrasive
cleaners or chlorine-based disinfectant
cleaners. They could damage the electrical
conductors, radio antenna elements or rear
window defroster elements.
ALUMINUM ALLOY WHEELS
Wash the wheels regularly with a sponge
dampened in a mild soap solution, especially
during winter months in areas where road
salt is used. If not removed, road salt can
discolor the wheels.
CAUTION
Follow the directions below to avoid stain-
ing or discoloring the wheels:
∙ Do not use a cleaner that uses strong acidor alkali contents to clean the wheels.
∙ Do not apply wheel cleaners to the wheels when they are hot. The wheel
temperature should be the same as ambi-
ent temperature.
∙ Rinse the wheel to completely remove the cleaner within 15 minutes after the
cleaner is applied.
CHROME PARTS
Clean all chrome parts regularly with a non-
abrasive chrome polish to maintain the finish.
TIRE DRESSINGS
INFINITI does not recommend the use of tire
dressings. Tire manufacturers apply a coating
to the tires to help reduce discoloration of the
rubber. If a tire dressing is applied to the tires,
it may react with the coating and form a
compound. This compound may come off the
tire while driving and stain the vehicle paint.
If you choose to use a tire dressing, take the
following precautions:
∙ Use a water-based tire dressing. The coating on the tire dissolves more easily
than with an oil-based tire dressing.
∙ Apply a light coat of tire dressing to help prevent it from entering the tire
tread/grooves (where it would be diffi-
cult to remove).
∙ Wipe off excess tire dressing using a dry towel. Make sure the tire dressing is com-
pletely removed from the tire
tread/grooves.
∙ Allow the tire dressing to dry as recom- mended by tire dressing manufacturer.
Appearance and care7-3

WARNING
Do not allow wet seat belts to roll up in the
retractor. NEVER use bleach, dye or chemi-
cal solvents to clean the seat belts, since
these materials may severely weaken the
seat belt webbing.
CLEANING THE SEAT TRACKS
CAUTION
Periodically clean the seat tracks to pre-
vent reduction of ability to move the seats.
Clean periodically with a high-powered
vacuum cleaner. Dirt and debris may reduce
the ability to adjust the seat. A wet cleansing
agent may be used if necessary.
MOST COMMON FACTORS
CONTRIBUTING TO VEHICLE
CORROSION
Most vehicle corrosion is caused by:
∙ The accumulation of moisture-retaining dirt and debris in body panel sections,
cavities, and other areas.
∙ Damage to paint and other protective coatings caused by gravel and stone
chips or minor traffic collisions.
ENVIRONMENTAL FACTORS
INFLUENCE THE RATE OF
CORROSION
Moisture
Accumulation of sand, dirt and water on the
vehicle body underside can accelerate corro-
sion. Wet floor coverings will not dry com-
pletely inside the vehicle and should be re-
moved for drying to avoid floor panel
corrosion.
Relative humidity
Corrosion will be accelerated in areas of high
relative humidity, especially those areas where the temperatures stay above freezing
and where atmospheric pollution exists and
road salt is used.
Temperature
High temperatures accelerate the rate of cor-
rosion to those parts which are not well ven-
tilated.
Air pollution
Industrial pollution, the presence of salt in the
air in coastal areas, or heavy road salt use
accelerates the corrosion process. Road salt
also accelerates the disintegration of paint
surfaces.
PROTECT YOUR VEHICLE FROM
CORROSION
∙ Wash and wax your vehicle often to keep
the vehicle clean.
∙ Always check for minor damage to the paint and repair it as soon as possible.
∙ Keep drain holes at the bottom of the doors open to avoid water accumulation.
∙ Check the underbody for accumulation of sand, dirt or salt. If present, wash with
water as soon as possible.
