2014 MERCEDES-BENZ CLA wheel bolts

Cleaning the wheels
!Do notuse acidic wheel cleaning products
to remove brake dust. This could damage
wheel bolts and brake components.
!Do not park the vehicle for an extended
period straight after cleaning it, particularly
after having cleaned the wheels with wheel
cleaner. Wheel cleaners could cause
increased corrosion of the brake discs and
brake pads/linings. For this reason, you
should drive for a few minutes after
cleaning. Braking heats the brake discs and
the brake pads/linings, thus drying them.
The vehicle can then be parked.
Cleaning the paintwork
!Do not affix:
Rstickers
Rfilms
Rmagnetic plates or similaritems
to painted surfaces.You could otherwise
damage the paintwork.
XRemove dirt immediately, where possible,
while avoiding rubbing too hard.
XSoak insect remains with insect remover
and rinse off the treated areas afterwards.
XSoak bird droppings with water and rinse
off the treated areas afterwards.
XRemove coolant, brake fluid, tree resin,
oils, fuels and greases by rubbing gently
with a cloth soaked in petroleum ether or
lighter fluid.
XUse tar remover to remove tar stains.
XUse silicone remover to remove wax.
XUse a suitable touch-up stick, e.g. MB
Touch-Up Stick, to repair slight damage to
the paintwork quickly and provisionally.
The following cannot always be completely
repaired:
Rscratches
Rcorrosive deposits
Rareas affected by corrosion
Rdamage caused by inadequate care
In such cases, visit a qualified specialist
workshop.
If water no longer forms "beads" on the paint
surface, use the paint care products
recommended and approved by Mercedes-
Benz.This is the case approximately every
three to five months, depending on the
climate conditions and the care product used.
If the dirt has penetrated the paint surface or
if the paintwork has become dull, then the
paintwork should be cleaned. For cleaning,
please use the paint cleaner recommend and
approved by Mercedes Benz.
Do not use these care products in the sun or
on the hood while the hood is hot.
Matte finish care
!Never polish the vehicle or the light alloy
wheels. Polishing causes the finish to
shine.
!The following may cause the paint to
become shiny and thus reduce the matte
effect:
RVigorous rubbing with unsuitable
materials.
RFrequent use of car washes.
RWashing the vehicle in direct sunlight.
!Never use paint cleaner, buffing or
polishing products, or gloss preserver, e.g.
wax. These products are only suitable for
high-gloss surfaces. Their use on vehicles
with matte finish leads to considerable
surface damage (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 matte finish. This will help you to avoid
damage to the paintwork due to incorrect
treatment.

Maintenance and care
Z

Observe the following when raising the
vehicle:
Rto raise the vehicle, only use the vehicle-
specific jack that has been tested and
approved by Mercedes-Benz.Ifused
incorrectly, the jack could tip over with the
vehicle raised.
Rthe jack is designed only to raise and hold
the vehicle for a short time while a wheel
is being changed. It is not suited for
performing maintenance work under the
vehicle.
Ravoid changing the wheel on uphill and
downhill slopes.
Rbefore raising the vehicle, secure it from
rolling away by applying the parking brake
and inserting wheel chocks. Never
disengage the parking brake while the
vehicle is raised.
Rthe jack must be placed on a firm, flat and
non-slip surface. On a loose surface, a
large, load-bearing underlay must be used.
On a slippery surface, a non-slip underlay
must be used, e.g. rubber mats.
Rdo not use wooden blocks or similar
objects as a jack underlay.Otherwise, the
jack will not be able to achieve its load-
bearing capacity due to the restricted
height.
Rmake sure thatthe distance between the
underside of the tires and the ground does
not exceed 1.2 in (3 cm).
Rnever place your hands and feet under the
raised vehicle.
Rnever lie under the raised vehicle.
Rnever start the engine when the vehicle is
raised.
Rnever open or close a door or the tailgate
when the vehicle is raised.
Rmake sure that no persons are present in
the vehicle when the vehicle is raised.
!The jack is designed exclusively for
jacking up the vehicle at the jacking points.
Otherwise, your vehicle could be damaged.
Steel wheel with wheel trim
XVehicles with steel wheels:carefully
reach into two of the wheel trim openings
and remove the wheel trim.
XUsing lug wrench, loosen the bolts on
the wheel you wish to change by about one
full turn. Do not unscrew the bolts
completely.
The jacking points are located just behind the
wheel housings of the front wheels and just
in front of the wheel housings of the rear
wheels (arrows).
