INFINITI Q50-HYBRID 2018 Owners Manual

6-8In case of emergency
CAUTION
.Do not continue to drive if your
vehicle overheats. Doing so could
cause engine damage or a vehicle fire.
. To avoid the danger of being scalded,
never remove the radiator cap while
the engine is still hot. When the
radiator cap is removed, pressurized
hot water will spurt out, possibly
causing serious injury.
. Do not open the hood if steam is
coming out.
If your vehicle is overheating (indicated by an
extremely high temperature gauge reading),
or if you feel a lack of engine power, detect
abnormal noise, etc., take the following
steps:
1. Move the vehicle safely off the road, apply the parking brake and move the
shift lever to the P (Park) position.
Do not turn the INFINITI Direct Re-
sponse Hybrid
®System off.
2. Turn off the climate control. Open all the windows, move the heater or air condi-
tioner temperature control to maximum
hot and fan control to high speed. 3. If engine overheating is caused by climb-
ing a long hill on a hot day, run the engine
at a fast idle (approximately 1,500 rpm)
until the temperature gauge indication
returns to normal.
4. Get out of the vehicle. Look and listen for steam or coolant escaping from the
radiator before opening the hood. (If
steam or coolant is escaping, turn off the
hybrid system.) Do not open the hood
further until no steam or coolant can be
seen.
5. Open the engine hood.
WARNING
If steam or water is coming from the
engine, stand clear to prevent getting
burned.
6. Also check if the cooling fan is running. The radiator hoses and radiator should
not leak water. If coolant is leaking or the
cooling fan does not run, stop the hybrid
system.
WARNING
Be careful not to allow your hands, hair,
jewelry or clothing to come into contact
with, or get caught in, the engine cooling
fan. The engine cooling fan can start at
any time.
7. After the engine cools down, check the coolant level in the reservoir tank with
the engine running. Add coolant to the
reservoir tank if necessary. Have your
vehicle repaired. It is recommended you
visit an INFINITI retailer for this service.
IF YOUR VEHICLE OVERHEATS

When towing your vehicle, all State (Pro-
vincial in Canada) and local regulations for

7-2Appearance and care
In order to maintain the appearance of your
vehicle, it is important to take proper care of
it.
To protect the paint surface, wash your
vehicle as soon as you can:
.after a rainfall to prevent possible da-
mage 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
surface
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 the vehicle 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 cleaning. The acid may react
with some plastic vehicle compo-
nents, 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 de-
tergents, 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 again with plenty of clean
water.
Inside flanges, seams and folds on the doors,
hatches and hood are particularly vulnerable
to the effects of road salt. Therefore, these
areas must be regularly cleaned. Make sure
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.
Avoid leaving water spots on the paint
surface by using a damp chamois to dry the
vehicle.
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
appearance before reapplying wax.
An INFINITI retailer can assist you in choos-
ing the proper product.
. Wax your vehicle only after a thorough
washing. Follow the instructions sup-
plied with the wax.
CLEANING EXTERIOR

.Do not use a wax containing any abra-
sives, cutting compounds or cleaners
that may damage the vehicle finish.
Machine compound or aggressive polishing
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,
insects, and tree sap as quickly as possible
from the paint surface to avoid lasting
damage or staining. Special cleaning pro-
ducts are available at an INFINITI retailer or
any automotive accessory stores.
UNDERBODY
In areas where road salt is used in winter, the
underbody must be cleaned regularly. This
will 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 win-
dows, do not use sharp-edged tools,
abrasive cleaners or chlorine-based dis-
infectant cleaners. They could damage
the electrical conductors, radio antenna
elements or rear window defroster ele-
ments.
WHEELS
Wash the wheels when washing the vehicle
to maintain their appearance.
. Clean the inner side of the wheels when
the wheel is changed or the underside of
the vehicle is washed.
. Inspect wheel rims regularly for dents or
corrosion. Such damage may cause loss
of pressure or poor seal at the tire bead.
. INFINITI recommends that the road
wheels be waxed to protect against road
salt in areas where it is used during winter.
CAUTION
Do not use abrasive cleaners when
washing the wheels.
Aluminum alloy wheels
Wash regularly with a sponge dampened in a
mild soap solution, especially during winter
months in areas where road salt is used. Salt
could discolor the wheels if not removed.
CAUTION
Follow the directions below to avoid
staining or discoloring the wheels:
.
Do not use a cleaner that uses strong
acid or 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
ambient temperature.
. Rinse the wheel to completely re-
move the cleaner within 15 minutes
after the cleaner is applied.
Appearance and care7-3

7-4Appearance and care
Bright wheels (if so equipped)
The bright wheels use a different coating
process than typical aluminum alloy wheel
and they are not plated wheels. These
wheels are clear-coated and require the
following special cleaning. They should be
regularly washed with a soft sponge soaked
in a lot of water. After washing with water,
wipe clean with a dry, soft cloth and dry
completely. When there is chemical or tire
wax, or dirt such as an antifreeze agent on
the surface, wash them with water as soon
as possible.
CAUTION
.The surfaces of the wheels use a
different coating process than typical
aluminum alloy wheels. Do not use
aluminum alloy wheel cleaners or
abrasive cleaners to clean the wheels.
Using such cleaners could damage the
wheel surfaces.
. Do not use an automatic car wash if
the vehicle is equipped with bright
wheels. The wheel coating may be
damaged.
. Do not use a brush to wash the
wheels if the vehicle is equipped with
bright wheels. The wheel coating may be damaged.
CHROME PARTS
Clean chrome parts regularly with a non-
abrasive chrome polish to maintain the
finish.
TIRE DRESSING
INFINITI does not recommend the use of tire
dressings. Tire manufacturers apply a coat-
ing 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
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 difficult to
remove).
. Wipe off excess tire dressing using a dry
towel. Make sure the tire dressing is
completely removed from the tire tread/
grooves. .
Allow the tire dressing to dry as recom-
mended by tire dressing manufacturer.

Occasionally remove loose dust from the
interior trim, plastic parts and seats using a
vacuum cleaner or soft bristled brush. Wipe
the vinyl and leather surfaces with a clean,
soft cloth dampened in mild soap solution,
then wipe clean with a dry soft cloth.
Regular care and cleaning is required in order
to maintain the appearance of the leather.
Before using any fabric protector, read the
manufacturer’s recommendations. Some
fabric protectors contain chemicals that
may stain or bleach the seat material.
Use a cloth dampened only with water, to
clean the meter and gauge lens.
WARNING
Do not use water or acidic cleaners (hot
steam cleaners) on the seat. This can
damage the seat or occupant classifica-
tion sensors. This can also affect the
operation of the air bag system and
result in serious personal injury.
CAUTION
.Never use benzine, thinner, or any
similar material. .
For cleaning, use a soft cloth, dam-
pened with water. Never use a rough
cloth, alcohol, benzine, thinner or any
kind of solvent or paper towel with a
chemical cleaning agent. They will
scratch or cause discoloration to the
lens.
. Do not spray any liquid such as water
on the meter lens. Spraying liquid
may cause the system to malfunction.
. Small dirt particles can be abrasive
and damaging to the leather surfaces
and should be removed promptly. Do
not use saddle soap, car waxes,
polishes, oils, cleaning fluids, sol-
vents, detergents or ammonia-based
cleaners as they may damage the
leather’s natural finish.
. Do not clean the interior or trunk
using water. If water contacts the
Lithium-ion (Li-ion) battery, it may
cause a short circuit and damage the
battery.
. Only use fabric protectors approved
by INFINITI.
. Do not use glass or plastic cleaner on
meter or gauge lens covers. It may
damage the lens cover.
