MERCEDES-BENZ CLA 2023 Owners Manual

Function of 4MATIC
4MATIC ensures that all four wheels are driven. Together with ESP n
and 4ETS, 4MATIC improves
the traction of your vehicle whenever a driven wheel spins due to insuPcient traction.
If you fail to adapt your driving style, 4MATIC can
neither reduce the risk of an accident nor override the laws of physics. 4MATIC cannot take accountof road, weather and traPc conditions. 4MATIC is
only an aid. You are responsible especially for
maintaining a safe distance from the vehicle in front, for vehicle speed, for braking in good time
and for staying in lane.\bIn wintry road conditions, the maximum eMect
of 4MATIC can be achieved only if you use
winter tires (M\fS tires), with snow chains if
necessary.Refueling
Refueling the vehicle
&WARNING Risk of Nre or explosion from
fuel
Fuels are highly Oammable.
Fire, open Oames, smoking and creating
sparks must be avoided.Before refueling, switch oM the vehicle
and, if installed, the stationary heater,
and leave them switched oM during refu-
eling.&WARNING Risk of injury from fuels
Fuels are poisonous and hazardous to your
health.
Do not swallow fuel or let it come into
contact with skin, eyes or clothing.Do not inhale fuel vapor.Keep children away from fuel.Keep doors and windows closed during
the refueling process.
If you or other people come into contact with
fuel, observe the following:
Immediately rinse fuel oM your skin with
soap and water.If fuel comes into contact with your eyes, immediately rinse them thoroughly with
clean water. Seek medical attention
immediately.If you swallow fuel, seek medical atten-
tion immediately. Do not induce vomit-
ing.Change immediately out of clothing that has come into contact with fuel.&WARNING Risk of Nre and explosion due
to electrostatic charge
Electrostatic charge can ignite fuel vapor.
Driving and parking149

Before you open the fuel Nller cap or
take hold of the pump nozzle, touch the metallic vehicle body.To avoid creating another electrostatic
charge, do not get into the vehicle again
during the refueling process.*NOTE Damage caused by the wrong fuel
Vehicles with a gasoline engine:
Even small amounts of the wrong fuel could
result in damage to the fuel system, the
engine and the emission control system.
Only refuel with low-sulfur spark-ignition
engine fuel.
This fuel may contain up to 10% ethanol. Your vehicle is suitable for use with E10 fuel.
Never refuel with one of the following fuels: = Diesel
= Gasoline with more than 10% ethanol by
volume, e.g. E15, E85, E100
= Gasoline with more than 3% methanol by
volume, e.g. M15, M30, M85, M100
= Gasoline with additives containing metal
If you have accidentally refueled with the
wrong fuel:Do not switch on the vehicle.Consult a qualiNed specialist workshop.*NOTE Do not use diesel to refuel vehicles
with a gasoline engine
If you have accidentally refueled with the
wrong fuel:
= Do not switch on the vehicle. Otherwise
fuel can enter the engine.
Even small amounts of the wrong fuel
could result in damage to the fuel system and the engine. The repair costs are high.
Consult a qualiNed specialist workshop.Have the fuel tank and fuel lines drained
completely.*NOTE Damage to the fuel system due to
overNlling the fuel tankOnly Nll the fuel tank until the pump noz-
zle switches oM.
If too much fuel has been added due, for
example, to a faulty Nlling pump:
Do not switch on the vehicle.Consult a qualiNed specialist workshop.*NOTE Fuel may spray out when you
remove the fuel pump nozzleOnly Nll the fuel tank until the pump noz-
zle switches oM.
Requirements
= The vehicle is unlocked.
Observe the notes on service Ouids and fuel.
Only refuel with fuel that has at least the octane rating speciNed in the information label in the fuel
Nller Oap. Otherwise, engine output may be
reduced and fuel consumption increased.

Parking
Parking the vehicle
&WARNING Risk of accident and injury
caused by an insuPciently secured vehi-
cle rolling away
If the vehicle is not securely parked suP-
ciently, it can roll away in an uncontrolled way
even at a slight downhill gradient.
On uphill or downhill gradients, turn the
front wheels so that the vehicle rolls
towards the curb if it starts moving.Apply the parking brake.Switch the transmission to position ].&WARNING Risk of Nre caused by hot
exhaust system parts
Flammable materials such as leaves, grass or
twigs may ignite.
Park the vehicle so that no Oammable
material can come into contact with hot
vehicle components.In particular, do not park on dry grass- land or harvested grain Nelds.&WARNING Risk of accident and injury due
to children les unattended in the vehicle
If you leave children unattended in the vehicle,
they could, in particular:
= open doors, thereby endangering other
persons or road users.
= get out and be struck by oncoming traPc.

=operate vehicle equipment and become
trapped, for example.
In addition, the children could also set the
vehicle in motion by, for example:
= releasing the parking brake.
= changing the gearbox position.
= starting the vehicle.Never leave children unattended in the
vehicle.When leaving the vehicle, always take the key with you and lock the vehicle.Keep the key out of reach of children.*NOTE Damage to the vehicle due to it roll-
ing awayAlways secure the vehicle against rolling away.Bring the vehicle to a standstill by depressing
the brake pedal.On uphill or downhill gradients, turn the front
wheels so that the vehicle rolls towards the
curb if it starts moving.Apply the electric parking brake.Engage transmission position ] in a station-
ary vehicle with the brake pedal depressed
(  page 145).Switch oM the vehicle by pressing button 1.Release the service brake slowly.Get out of the vehicle and lock it.\bWhen you park the vehicle, you can still oper-

&DANGER Risk of death caused by exhaust
gases
Combustion engines emit poisonous exhaust
gases such as carbon monoxide. Inhaling
these exhaust gases is hazardous to health
and leads to poisoning.
