2015 MERCEDES-BENZ CLA SHOOTING BRAKE catalytic converter

depress the brake pedal. Only then can the
parking lock be deactivated.
All vehicles (except Mercedes-AMG vehi-
cles): if you do not depress the brake pedal,
the DIRECT SELECT lever can still be moved
but the parking lock remains engaged.
Mercedes-AMG vehicles: if you do not
depress the brake pedal, the selector lever
can still be moved but the parking lock
remains engaged.
Vehicles with automatic transmission: at
transmission fluid temperatures below
Ò20 †, you can only shift out of position Pinto
another transmission position when the
engine is running.
i Vehicles with automatic transmis-
sion: upshifts take place at higher engine
speeds after a cold start. This helps the
catalytic converter to reach its operating
temperature more quickly.
Vehicles with automatic transmission:
information on automatically releasing the
electric parking brake (Y page 193).
Pulling away with a trailer To ensure that you do not roll backwards
when pulling away on an uphill slope, apply
the electric parking brake.
X Press and hold handle :.
The electric parking brake continues to
brake and prevent the vehicle from rolling
backwards. The red
!indicator lamp in the instru-
ment cluster remains lit.
X Depress the accelerator pedal.
X As soon as the vehicle/trailer combination
is held by the driving force of the engine,
release lever :.
the electric parking brake is released
The red !indicator lamp in the instru-
ment cluster goes out.
For further information on the electric parking
brake, see (Y page 193).
Hill start assist Hill start assist helps you when pulling away
forwards or in reverse on an uphill gradient. It
holds the vehicle for a short time after you
have removed your foot from the brake pedal.
This gives you enough time to move your foot from the brake pedal to the accelerator pedal and depress it before the vehicle begins to
roll. G
WARNING
After a while, hill start assist no longer holds
the vehicle and it may roll away. There is a risk of an accident and injury.
Therefore, quickly move your foot from the
brake pedal to the accelerator pedal. Never
leave the vehicle when it is held by hill start
assist.
Hill start assist is not active if:
R you are pulling away on a level road or a
downhill gradient
R on vehicles with automatic transmission,
the transmission is in position N
R the electric parking brake is applied
R ESP ®
is malfunctioning

X Pull dipstick :out of the dipstick tube.
X Wipe off oil dipstick :.
X Slowly slide oil dipstick :into the guide
tube to the stop, and take it out again.
If the level is between MIN mark =and
MAX mark ;, the oil level is correct.
X If the oil level has dropped to MIN mark =
or below, top up with 1.0 l of engine oil.
Topping up engine oil G
WARNING
Certain components in the engine compart-
ment could be very hot, e.g. the engine, the
radiator and parts of the exhaust system.
There is a risk of injury when accessing the
engine compartment.
As far as possible, allow the engine to cool
down and only touch the components descri- bed in the following. G
WARNING
If engine oil comes into contact with hot com- ponents in the engine compartment, it may
ignite. There is a risk of fire and injury.
Make sure that engine oil does not spill out
over the filler neck. Allow the engine to cool
down and thoroughly clean the components
that have come into contact with engine oil
before you start the engine. H
Environmental note
When topping up the oil, take care not to spill
any. If oil enters the soil or waterways, it is
harmful to the environment.
! Only use engine oils and oil filters that
have been approved for vehicles with a ser-
vice system. You can obtain a list of the
engine oils and oil filters tested and
approved in accordance with the
Mercedes-Benz Specifications for Service
Products at any Mercedes-Benz Service
Centre.
Damage to the engine or exhaust system is caused by the following:
R using engine oils and oil filters that have
not been specifically approved for the
service system
R changing the engine oil and oil filter after
missing the change interval required by
the service system
R using engine oil additives
! Do not add too much oil. Topping up with
too much engine oil can result in damage to
the engine or to the catalytic converter.
Have excess engine oil siphoned off. Engine compartment
337Maintenance and care Z

Jump-starting
For the jump-starting procedure, use only the jump-starting connection point, consisting of a positive terminal and an earth point, in the engine compartment. G
WARNING
Battery acid is caustic. There is a risk of injury.
Avoid contact with the skin, eyes or clothing. Do not breathe in any battery gases. Do not lean over the battery. Keep the batteries out of the reach of children. Immediately rinse off battery acid
thoroughly with plenty of clean water and seek medical attention at once. G
WARNING
During charging and jump-starting, explosive gases can escape from the battery. There is a risk of an explosion.
Particularly avoid fire, naked flames, creating sparks and smoking. Ensure there is sufficient
ventilation while charging and jump-starting. Do not lean over a battery. G
WARNING
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.
R Make sure that the positive terminal of a connected battery does not come into contact with
vehicle parts.
R Never place metal objects or tools on a battery.
R It is important that you observe the described order of the battery terminals when connecting
and disconnecting a battery.
R When jump-starting, make sure that the battery poles with identical polarity are connected.
R It is particularly important to observe the described order when connecting and disconnecting
the jump leads.
R Never connect or disconnect the battery terminals while the engine is running. G
WARNING
A discharged battery can freeze at temperatures below freezing point. When jump-starting the
vehicle or charging the battery, gases can escape from the battery. There is a risk of an explosion.
Allow the frozen battery to thaw out before charging it or jump-starting.
! Vehicles with a petrol engine:
avoid repeated and lengthy starting attempts. Otherwise,
the non-combusted fuel may damage the catalytic converter.
If the indicator/warning lamps do not light up at low temperatures, it is very likely that the
discharged battery has frozen. In this case you may neither jump-start the vehicle nor charge
the battery. Let the battery thaw first. The service life of a battery that has been thawed may
be reduced. The starting characteristics may be impaired, especially at low temperatures.
Have the thawed battery checked at a qualified specialist workshop. 360
