low oil pressure MERCEDES-BENZ GLC COUPE 2016 Owners Manual

aged tyres or chassis components replaced
immediately.
! Always maintain a distance of at least 30 cm
between the vehicle and the high-pressure
cleaner nozzle. Information about the correct
distance is available from the equipment
manufacturer.
Move the high-pressure cleaner nozzle
around when cleaning your vehicle.
Do not aim directly at any of the following:
R tyres
R door gaps, roof gaps, joints etc.
R electrical components
R battery
R plug connectors
R lamps
R seals
R trim elements
R ventilation slots
Damage to seals or electrical components
can lead to leaks or failures.
! Vehicles with decorative film: parts of your
vehicle are covered with a decorative film.
Maintain a distance of at least 70 cm between the parts of the vehicle covered with the film
and the nozzle of the high pressure cleaner.
Information about the correct distance is
available from the equipment manufacturer.
Move the high-pressure cleaner nozzle
around whilst cleaning.
! If the key is within the rear detection range
of KEYLESS-GO, the following situations, for
example, could lead to the unintentional
opening of the tailgate:
R using a car wash
R using a high-pressure cleaner
Make sure that the key is at least 3 m away
from the vehicle.
Cleaning the paintwork !
Do not affix:
R stickers
R films
R magnetic plates or similar items
to painted surfaces. You could otherwise
damage the paintwork. Scratches, corrosive deposits, areas affected by
corrosion and damage caused by inadequate
care cannot always be completely repaired. In
such cases, visit a qualified specialist workshop.
X Remove impurities immediately, where pos-
sible, whilst avoiding rubbing too hard.
X Soak insect remains with insect remover and
rinse off the treated areas afterwards.
X Soak bird droppings with water and rinse off
the treated areas afterwards.
X Remove coolant, brake fluid, tree resins, oils,
fuels and greases by rubbing gently with a
cloth soaked in petroleum ether or lighter
fluid.
X Use tar remover to remove tar stains.
X Use silicone remover to remove wax.
Care and treatment of matt paintwork !
Never polish the vehicle or the light alloy
wheels. Polishing makes the paintwork shiny.
! The following may cause the paint to
become shiny and thus reduce the matt
effect:
R vigorous rubbing with unsuitable materials
R frequent use of car washes
R washing the vehicle in direct sunlight
! Never use paint cleaner, buffing or polishing
products, or gloss preserver, e.g. wax, for the purpose of paintwork care. These products
are only suitable for high-gloss surfaces. Their
use on vehicles with matt paintwork leads to
considerable surface damage or, more spe-
cifically, to shiny, spotted areas.
Always have paintwork repairs carried out at a
qualified specialist workshop.
! Do not use wash programs with a hot wax
treatment under any circumstances.
Observe these notes if your vehicle has a clear, matt finish. This will help you to avoid damage to the paintwork due to incorrect treatment.
These notes also apply to light-alloy wheels with
a clear matt finish.
The vehicle should preferably be washed by
hand using a soft sponge, car shampoo and
plenty of water.
Use only insect remover and car shampoo from the range of approved Mercedes-Benz care
products. Care

flash rust to form on the surface. You can
restore the original shine of the exhaust pipe by cleaning it regularly, especially in winter and
after washing the vehicle.
X Clean the exhaust pipe with a care product
tested and approved by Mercedes-Benz.
Cleaning the trailer tow hitch H
Environmental note
Dispose of oily and greasy cloths in an envi-
ronmentally-responsible manner.
! Do not clean the ball coupling with a high-
pressure cleaner. Do not use solvents.
The ball coupling must be cleaned if it becomes
dirty or corroded.
X Remove rust on the ball, e.g. with a wire
brush.
X Remove dirt with a clean, lint-free cloth or a
brush.
X After cleaning, lightly oil or grease the ball
coupling.
X Check that the vehicle's trailer tow hitch is
working properly.
You can also have the maintenance work on the
ball coupling and the trailer tow hitch carried out
by a qualified specialist workshop. Interior care
Cleaning the display !
For cleaning, do not use any of the following:
R alcohol-based thinner or petrol
R abrasive cleaning agents
R commercially-available household cleaning
agents
These may damage the display surface. Do
not put pressure on the display surface when cleaning. This could lead to irreparable dam-
age to the display.
X Before cleaning the display, make sure that it
is switched off and has cooled down.
X Clean the display surface using a commer-
cially available microfibre cloth and TFT/LCD
display cleaner.
X Dry the display surface using a dry microfibre
cloth. Cleaning the plastic trim G
WARNING
Care products and cleaning agents containing solvents can cause surfaces in the cockpit to
become porous. This could result in plastic
parts breaking away when the airbags are
deployed. There is a danger of injury.
Do not use care products and cleaning agents containing solvents to clean the cockpit.
! Never attach the following to plastic surfa-
ces:
R stickers
R films
R perfume oil container or similar
You could otherwise damage the plastic.
! Do not allow cosmetics, insect repellent or
sunscreen to come in contact with the plastic trim. This maintains the high-quality look of
the surfaces.
X Wipe the plastic trim with a damp, lint-free
cloth, e.g. a microfibre cloth.
X Heavy soiling: use care and cleaning prod-
ucts recommended and approved by
Mercedes-Benz.
The surface may change colour temporarily.
Wait until the surface is dry again.
Cleaning the steering wheel and selec-
tor lever X
Thoroughly wipe with a damp cloth or use
leather care agents that have been recom-
mended and approved by Mercedes-Benz.
Cleaning wood trim and trim elements !
Do not use solvent-based cleaning agents
such as tar remover, wheel cleaners, polishes
or waxes. There is otherwise a risk of damag- ing the surface. 336
CareMaintenance and care

The wear patterns on the front and rear tyres
differ depending on the operating conditions.
Interchange the wheels before a clear wear pat-
tern has formed on the tyres. Front tyres typi-
cally wear more on the shoulders, while rear
tyres wear more in the centre.
On vehicles that have front and rear wheels of
the same size, you can interchange the wheels
every 5,000 to 10,000 km depending on the
degree of tyre wear. Ensure the direction of
rotation is maintained.
Clean the contact surfaces of the wheel and the
brake disc thoroughly every time a wheel is
interchanged. Check the tyre pressure and, if
necessary, restart the tyre pressure loss warn-
ing system (Y page 361) or the tyre pressure
monitor (Y page 363). Direction of rotation
Tyres with a specified direction of rotation have additional benefits, e.g. if there is a risk of aqua- planing. These advantages can only be gained if
the tyres are fitted corresponding to the direc-
tion of rotation.
An arrow on the sidewall of the tyre indicates its correct direction of rotation. Storing wheels
Store wheels in a cool, dry and preferably dark
place if they are not being used. Protect the
tyres against oil, grease, petrol and diesel. Fitting a wheel
Preparing the vehicle X
Stop the vehicle on solid, non-slippery and
level ground.
X Apply the electric parking brake manually.
X Move the front wheels to the straight-ahead
position.
X Shift the transmission to position P.
X Make sure that the vehicle level is set to "Nor-
mal" on vehicles with AIR BODY CONTROL
(Y page 188).
X Switch off the engine.
X Vehicles without KEYLESS-GO: remove the
key from the ignition lock. X
Vehicles with KEYLESS-GO start-function
or KEYLESS-GO: open the driver's door.
The vehicle electronics now have status 0.
This is the same as the key having been
removed.
X Vehicles with KEYLESS-GO start function
or KEYLESS-GO: remove the Start/Stop but-
ton from the ignition lock (Y page 144).
X If included in the vehicle equipment, remove
the tyre-change tool kit from the vehicle.
X Safeguard the vehicle against rolling away.
i Apart from some country-specific variants,
vehicles are not equipped with tyre-changing
tools. Some tools for changing a tyre are spe- cific to the vehicle. For more information on
which tools are required to perform a wheel
change on your vehicle, consult a qualified
specialist workshop.
Necessary tyre-changing tools may include,
for example:
R Jack
R wheel chock
R Wheel wrench
R Centring pin
Securing the vehicle against rolling
away If your vehicle is equipped with a wheel chock, it
can be found in the tyre-change tool kit
(Y page 340).
The folding wheel chock is an additional secur-
ing measure to safeguard the vehicle from roll-
ing away, e.g. during a wheel change.
