2014 MERCEDES-BENZ CLA warning

Cleaning the seat covers
General notes
!Do notuse microfiber cloths to clean
genuine leather, artificial leather or
Alcantara® covers. If used often, these can
damage the cover.
iNote that regularcare is essential to
ensure that the appearance and comfort of
the covers is retained overtime.
Genuine leather seat covers
Leather is a natural product.
It exhibits natural surface characteristics, for
example:
RDifferences in the texture
RSigns of stretching and marking
RSlightnuances of color
These are characteristics of leather and not
material defects.
!To retain the natural appearance of the
leather, observe the followingcleaning
instructions:
RClean genuine leathercovers carefully
with a damp cloth and then wipe the
covers down with a dry cloth.
RMake sure that the leather does not
become soaked. It may otherwise
become rough and cracked.
ROnly use leather care agents that have
been tested and approved by Mercedes-
Benz. You can obtain these from a
qualified specialist workshop.
Seat covers of other materials
!Observe the following when cleaning:
RClean artificial leather covers with a cloth
moistened with a solution containing
1% detergent (e.g. dish washing liquid).
RClean cloth covers with a microfiber
cloth moistened with a solution
containing 1% detergent (e.g. dish
washing liquid). Rub carefully and always
wipe entire seat sections to avoid leaving
visible lines. Leave the seat to dry
afterwards. Cleaning results depend on
the type of dirt and how long it has been
there.
RClean Alcantara® covers with a damp
cloth. Make sure that you wipe entire
seat sections to avoid leaving visible
lines.
Cleaning the seat belts
GWARNING
Seat belts can become severely weakened if
bleached or dyed. This could cause the seat
belts to tear or fail, for instance, in the event
of an accident.This poses an increased risk
of injury or fatal injury.
Never bleach or dye the seat belts.
!Do not clean the seat belts using chemical
cleaning agents. Do not dry the seat belts
by heating at temperatures above 176 ‡
(80 †) or in direct sunlight.

properties) (Ypage 295)
Vehicle preparation is not necessary on
vehicles with MOExtended tires.
Ra TIREFIT kit (Ypage 294)
Information on changing/mounting a wheel
(Ypage 336).
XStop the vehicle on solid, non-slippery and
level ground, as far away as possible from
traffic.
XSwitch on the hazard warning lamps.
XSecure the vehicle against rolling away
(Ypage 153).
XIf possible, bring the frontwheels into the
straight-ahead position.
XSwitch off the engine.
XRemove the SmartKey from the ignition
lock.
XAll occupants must get out of the vehicle.
Make sure that they are not endangered as
they do so.
XMake sure that no one is near the danger
area while a wheel is being changed.
Anyone who is not directly assisting in the
wheel change should, for example, stand
behind the barrier.
XGet out of the vehicle. Pay attention to
traffic conditions when doing so.
XClose the driver's door.
iVehicles equipped with MOExtended tires
are not equipped with a TIREFIT kit at the
factory. It is therefore recommended that
you additionally equip your vehicle with a
TIREFIT kit if you mount tires that do not
feature run-flat properties, e.g. winter tires.
A TIREFIT kit can be obtained from a
qualified specialist workshop.
MOExtended tires (tires with run-flat
properties)
General notes
With MOExtended tires (tires with run flat
characteristics), you can continue to drive
your vehicle even if there is a total loss of
pressure in one or more tires. The affected
tire must not show any clearly visible damage.
You can recognize MOExtended tires by the
MOExtended marking which appears on the
sidewall of the tire. You will find this marking
next to the tire size designation, the load-
bearing capacity and the speed index
(Ypage 330).
MOExtended tires may only be used in
conjunction with an active tire pressure loss
warning system or with an active tire pressure
monitor.
If the pressure loss warning message
appears in the multifunction display:
RObserve the instructions in the display
messages (Ypage 234).
RCheck the tire for damage.
RIf driving on, observe the following notes.
The maximum driving distance is
approximately 50 miles (80 km) when the
vehicle is partially laden and approximately
18 miles (30 km) when the vehicle is fully
laden.
In addition to the vehicle load, the driving
distance possible depends upon:
RSpeed
RRoad condition
ROutside temperature
The driving distance possible in run-flat mode
may be reduced by extreme driving
Flat tire295
Breakdown assistance

conditions/maneuvers, or it can be increased
through a moderate style of driving.
The maximum permissible distance which
can be driven in run-flat mode is counted from
the moment the tire pressure loss warning
appears in the multifunction display.
You mustnot exceed a maximum speed of
50 mph (80 km/h).
iWhen replacing one or all tires, make sure
that you use only tires:
Rof the size specified for the vehicle and
Rmarked "MOExtended"
If a tire has gone flat and cannot be
replaced with a MOExtended tire, a
standard tire may be used as a temporary
measure. Make sure that you use the
proper size and type (summer or winter
tire).
iVehicles equipped with MOExtended tires
are not equipped with a TIREFIT kit at the
factory. It is therefore recommended that
you additionally equip your vehicle with a
TIREFIT kit if you mount tires that do not
feature run-flat properties, e.g. winter tires.
A TIREFIT kit can be obtained from a
qualified specialist workshop.
Important safety notes
GWARNING
When driving in emergency mode, the driving
characteristics deteriorate, e.g. when
cornering, accelerating quickly and when
braking. There is a risk of an accident.
Do not exceed the stated maximum speed.
Avoid abrupt steering and driving maneuvers,
and driving over obstacles (curbs, potholes,
off-road). This applies in particular to a laden
vehicle.
Stop driving in emergency mode if:
Ryou hear banging noises.
Rthe vehicle starts to shake.
Ryou see smoke and smell rubber.
RESP®is intervening constantly.
Rthere are tears in the sidewalls of the tire.
After driving in emergency mode, have the
wheel rims checked at a qualified specialist
workshop with regard to their further use. The
defective tire must be replaced in every case.
TIREFIT kit
Important safety notes
GWARNING
In the following situations, the tire sealant is
unable to provide sufficient breakdown
assistance, as it is unable to seal the tire
properly:
Rthere are cuts or punctures in the tire larger
than those mentioned above.
Rthe wheel rim is damaged.
Ryou have driven at very low tire pressures
or on a flat tire.
There is a risk of an accident.
Do not drive any further. Contact a qualified
specialist workshop.
GWARNING
The tire sealant is harmful and causes
irritation. It must not come into contact with
your skin, eyes or clothing or be swallowed.
Do not inhale TIREFIT fumes. Keep tire sealant
away from children. There is a risk of injury.
If you come into contact with the tire sealant,
observe the following:
RRinse off the tire sealant from your skin
immediately with water.
RIf the tire sealant comes into contact with
your eyes, immediately rinse them
thoroughly with clean water.
RIf tire sealant is swallowed, immediately
rinse your mouth out thoroughly and drink
plenty of water. Do not induce vomiting,
and seek medical attention immediately.
296Flat tire
Breakdown assistance

iFirst, tire sealant is pumped into the tire.
The pressure can briefly rise to
approximately 500 kPa (5 bar/73 psi).
Do notswitch off the tire inflation
compressor during this phase.
XLet the tire inflation compressor run for a
maximum of tenminutes. The tire should
thenhave attained a pressure of at least
200 kPa (2.0 bar/29 psi).
!Do notoperate the tire inflation
compressor for longer than ten minutes at
a time without a break. It may otherwise
overheat.
The tire inflation compressor can be
operated again once it has cooled down.
Ifapressure of 200 kPa(2.0 bar/29 psi) has
been attained after a maximum of after ten
minutes, see (Ypage 298).
Ifapressure of 200 kPa(2.0 bar/29 psi) has
not been attained after a maximum of ten
minutes, see (Ypage 298).
iIf tire sealant leaks out, allow it to dry.It
can then be removed like a layeroffilm.
If your clothes are soiled with tire sealant,
have themcleaned with perchloroethylene
at a dry cleaner as soon as possible.
Tire pressure not reached
Ifapressure of 200 kPa(2.0 bar/29 psi) has
not been achieved after ten minutes:
XSwitch off the tire inflation compressor.
XUnscrew the filler hose from the valve of
the faulty tire.
XVery slowly drive forwards or reverse
approximately 30 ft (10 m).
XPump up the tire again.
After a maximum of ten minutes, the tire
pressure must be at least 200 kPa (2.0 bar/
29 psi).
GWARNING
If the required tire pressure is not reached
after the specified time, the tire is too badly
damaged. The tire sealant cannot repair the
tire in this instance. Damaged tires and a tire
pressure that is too low can significantly
impair the vehicle's braking and driving
characteristics. There is a risk of accident.
Do not continue driving. Contact a qualified
specialist workshop.
Tire pressure reached
GWARNING
Atire temporarily sealed with tire sealant
impairs the driving characteristics and is not
suitable for higher speeds. There is a risk of
accident.
You should therefore adapt your driving style
accordingly and drive carefully. Do not exceed
the specified maximum speed with a tire that
has been repaired using tire sealant.
!After use, excess tire sealant may run out
of the filler hose. This could cause stains.
Therefore, place the filler hose in the plastic
bag that contained the TIREFIT kit.
HEnvironmental note
Have the used tire sealant bottle disposed of
professionally, e.g. ataqualified specialist
workshop.
Ifatire pressure of 200 kPa(2.0 bar/29 psi)
has beenachieved afterten minutes:
XSwitch off the tire inflation compressor.
XUnscrew the filler hose from the valve of
the faulty tire.
XStow the tire sealant bottle and the tire
inflation compressor.
XPull away immediately.
The maximum speed for a tire sealed with tire
sealant is 50 mph(80km/h). The upper part
of the TIREFIT sticker must be affixed to the
instrument cluster in the driver's field of
vision.
298Flat tire
Breakdown assistance

XStop after driving for approximately ten
minutes and check the tire pressure with
the tire inflation compressor.
The tire pressure mustnow be at least
130 kPa (1.3 bar/19 psi).
GWARNING
If the required tire pressure is not reached
after driving for a short period, the tire is too
badly damaged. The tire sealant cannot repair
the tire in this instance. Damaged tires and a
tire pressure that is too low can significantly
impair the vehicle's braking and driving
characteristics. There is a risk of accident.
Do not continue driving. Contact a qualified
specialist workshop.
XCorrect the tire pressure if it is still at least
130 kPa (1.3 bar/19 psi) (for the values,
see the Tire and Loading Information
placard on the driver's side B-pillar or tire
pressure table on the fuel filler flap).
XTo increase the tire pressure:switch on
the tire inflation compressor.
XTo reduce the tire pressure:depress
pressure release buttonnext to
pressure gauge.
XTo remove the tire sealant bottle from the
tire inflation compressor, press together
the locking tabs on the yellow cap.
XPull the tire sealant bottle out of the tire
inflation compressor.
The filler hose remains attached to the tire
sealant bottle.
XStow the tire sealant bottle and the tire
inflation compressor.
XDrive to the nearest qualified specialist
workshop and have the tire changed there.
XHave the tire sealant bottle and the filler
hose replaced as soon as possible at a
qualified specialist workshop.
XHave the tire sealant bottle replaced every
four years at a qualified specialist
workshop.

In the event of a short circuit or a similar
incident, contact a qualified specialist
workshop immediately. Do not drive any
further. You should have all work involving the
battery carried out ataqualified specialist
workshop.
GWARNING
Electrostatic build-up can lead to the creation
of sparks, which could ignite the highly
explosive gases of a battery. There is a riskof
an explosion.
Before handling the battery, touch the vehicle
body to remove any existing electrostatic
build-up.
The highly flammable gas mixture forms when
charging the battery as well as when jump-
starting.
Always make sure that neither you northe
battery is electrostatically charged.Abuild-
up of electrostaticcharge can be caused, for
example:
Rby wearing clothing made from synthetic
fibers
Rdue to friction between clothing and seats
Rif you push or pull the battery across the
carpet or other synthetic materials
Rif you wipe the battery with a cloth
GWARNING
During the charging process, a battery
produces hydrogen gas. If a short circuit
occurs or sparks are created, the hydrogen
gas can ignite. There is a risk of an explosion.
RMake sure that the positive terminal of a
connected battery does not come into
contact with vehicle parts.
RNever place metal objects or tools on a
battery.
RIt is important that you observe the
described order of the battery terminals
when connecting and disconnecting a
battery.
RWhen jump-starting, make sure that the
battery poles with identical polarity are
connected.
RIt is particularly important to observe the
described order when connecting and
disconnecting the jumper cables.
RNever connect or disconnect the battery
terminals while the engine is running.
GWARNING
Battery acid is caustic. There is a risk of injury.
Avoid contact with the skin, eyes or clothing.

There is a risk of an explosion.
Allow the frozen battery to thaw out before
charging it or jump-starting.
!Only use battery chargers with a
maximum charging voltage of 14.8 V.
!Only charge the battery using the jump-
starting connection point.
The jump-starting connection point is in the
engine compartment (Ypage 303).
XOpen the hood.
XConnect the battery charger to the positive
terminal and ground point in the same
order as when connecting the donor
battery in the jump-starting procedure
(Ypage 303).
If, at low temperatures, the indicator lamps/
warning lamps in the instrument cluster do
not light up, it is highly likely that the
discharged battery has frozen.Inthis case
you may neither jump-start the vehicle nor
charge the battery. The service life of a
thawed-out battery may be shorter. The
starting characteristics can be impaired,
particularly at low temperatures. Have the
thawed-out battery checked at a qualified
specialist workshop.
Only charge the installed battery with a
battery charger which has been tested and
approved by Mercedes-Benz. An accessory
battery charge unit specially adapted for
Mercedes-Benzvehicles and tested and
approved by Mercedes-Benzis available. It
permits the charging of the battery in its
