Do not swallow fuel or let it come into contact
with skin, eyes or clothing. Do not inhale fuel
vapours. Keep fuels out of the reach of chil-
dren.
If you or others come into contact with fuel,
observe the following:
R Wash the fuel off any affected areas of skin
with water and soap immediately.
R If you get fuel in your eyes, rinse them thor-
oughly with clean water immediately. Seek
immediate medical attention.
R If fuel is swallowed, seek immediate medi-
cal attention. Do not induce vomiting.
R Change any clothing that has come into
contact with fuel immediately. G
WARNING
Electrostatic charge can cause sparks and
thereby ignite fuel vapours. There is a risk of
fire and explosion.
Always touch the vehicle body before opening the fuel filler flap or touching the fuel pump
nozzle. This discharges any electrostatic
charge that may have built up. G
WARNING
Vehicles with a diesel engine:
If you mix diesel fuel with petrol, the flash
point of this fuel mixture is lower than that of pure diesel fuel. When the engine is running,
components in the exhaust system may over-
heat unnoticed. There is a risk of fire.
Never refuel with petrol. Never add petrol to
diesel fuel.
! Do not use diesel to refuel vehicles with a
petrol engine. Do not switch on the ignition if you accidentally refuel with the wrong fuel.
Otherwise, the fuel will enter the fuel system.
Even small amounts of the wrong fuel can
result in damage to the fuel system and the
engine. Notify a qualified specialist workshop
and have the fuel tank and fuel lines drained
completely.
! Do not use petrol to refuel vehicles with a
diesel engine. Do not switch on the ignition if you accidentally refuel with the wrong fuel. Otherwise, fuel can enter the fuel system.
Even small amounts of the wrong fuel could
result in damage to the fuel system and the
engine. The repair costs are high. Notify a
qualified specialist workshop and have the
fuel tank and fuel lines drained completely.
! Overfilling the fuel tank could damage the
fuel system.
! Take care not to spill any fuel on painted
surfaces. You could otherwise damage the
paintwork.
! Use a filter when adding fuel from a fuel can.
The fuel lines and/or the fuel injection system could otherwise be blocked by particles fromthe fuel can.
Do not get back into the vehicle during the refu-
elling process; Otherwise, electrostatic charge
could build up again.
If you overfill the fuel tank, some fuel may spray out when you remove the fuel pump nozzle.

not exceed the maximum permissible speed for
your vehicle/trailer combination. Notes on towing a trailer
General notes Trailer towing is not possible on the following
models:
R CLA 180 d BlueEFFICIENCY Edition
R CLA 250 Sport
R CLA 250 Sport 4MATIC
R Mercedes‑AMG CLA 45 4MATIC
When towing a trailer, set the tyre pressure on
the rear axle of the towing vehicle for the max-
imum load. Further information on the tyre pres-
sure table in the fuel filler flap (Y page 313).
Please note that when towing a trailer, the fol-
lowing driving systems have limited availability
or are not available at all.
R Parking Assist PARKTRONIC (Y page 177)
R Blind Spot Assist (Y page 192)
The height of the ball coupling changes with the
load of the vehicle. If necessary, use a trailer
with a height-adjustable drawbar.
You will find fitting dimensions and loads under "Technical data" (Y page 334).
Driving tips Observe the notes on ESP
®
trailer stabilisation
(Y page 72).
The maximum permissible speed for vehicle/
trailer combinations depends on the type of
trailer. Before beginning the journey, check the
trailer's documents to see what the maximum
permitted speed is. Observe the legally prescri-
bed maximum speed in the relevant country.
For certain Mercedes-Benz vehicles, the maxi-
mum permissible rear axle load is increased
when towing a trailer. See the "Technical data"
section to find out whether this applies to your
vehicle. If you utilise any of the added maximum rear axle load when towing a trailer, the vehicle/
trailer combination may not exceed a maximum speed of 100 km/h for reasons concerning the
operating permit. This also applies in countries
in which the permissible maximum speed for
vehicle/trailer combinations is above
100 km/h. When towing a trailer, your vehicle's handling
characteristics will be different to when driving
without a trailer and the vehicle will consume
more fuel.
Shift into a lower gear in good time on long and steep downhill gradients. For vehicles with auto-
matic transmission, you need to have selected
manual drive program M(Y page 150).
This also applies if you have activated cruise
control, SPEEDTRONIC or Distance Pilot
DISTRONIC.
This will use the braking effect of the engine, so
less braking will be required to maintain the
vehicle speed. This relieves the load on the
brake system and prevents the brakes from
overheating and wearing too quickly. If you need additional braking, depress the brake pedal
repeatedly rather than continuously.
Briefly depressing the accelerator pedal on
downhill gradients while the manual drive pro-
gram Mis temporarily activated (vehicles with
automatic transmission): the automatic trans-
mission may switch back to the last active auto-
matic drive program Eor S. The automatic trans-
mission may shift to a higher gear. This can
reduce the engine's braking effect.
Driving tips R
Maintain a greater distance to the vehicle in
front than when driving without a trailer.
R Avoid braking abruptly. If possible, brake gen-
tly at first to allow the trailer to run on. Then,
increase the braking force rapidly.
R The values given for gradient-climbing capa-
bilities from a standstill refer to sea level.
When driving in mountainous areas, note that
the power output of the engine, and conse-
quently the vehicle's gradient-climbing capa-
bility from a standstill, decrease with increas-
ing altitude.
If the trailer swings from side to side:
X Do not accelerate under any circumstances
X Do not countersteer
X Brake, if necessary 196

pressure that is too low can significantly
impair the vehicle's braking and driving char-
acteristics. There is a risk of accident.
Do not continue driving. Contact a qualified
specialist workshop.
Tyre pressure reached G
WARNING
A tyre temporarily sealed with tyre 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 tyre that
has been repaired using tyre sealant.
The maximum permissible speed for a tyre
sealed with tyre sealant is 80 km/h. The upper
part of the TIREFIT sticker must be affixed to the
instrument cluster where it will be easily seen by
the driver.
If a tyre pressure of 200 kPa (2.0 bar/29 psi) has been attained after ten minutes:
X Switch off the tyre inflation compressor.
X Unscrew the filler hose from the valve of the
faulty tyre.
Please note that tyre sealant may leak out
when unscrewing the filler hose.
X Stow the tyre sealant bottle, the tyre inflation
compressor and the warning triangle.
X Pull away immediately.
X Stop after driving for approximately ten
minutes and check the tyre pressure with the
tyre inflation compressor.
The tyre pressure must now be at least
130 kPa (1.3 bar/19 psi). G
WARNING
If the required tyre pressure is not reached
after driving for a short period, the tyre is too badly damaged. The tyre sealant cannot
repair the tyre in this instance. Damaged tyres and a tyre pressure that is too low can signif-
icantly impair the vehicle's braking and driv-
ing characteristics. There is a risk of accident. Do not continue driving. Contact a qualified
specialist workshop.
i In your vehicle, you will find a sticker with
the Mercedes-Benz Service24h telephone
number, e.g. on the B-pillar on the driver's
side.
X Correct the tyre pressure if it is still at least
130 kPa (1.3 bar/19 psi). See the tyre pres-
sure table on the fuel filler flap for values.
X To increase the tyre pressure: switch on
the tyre inflation compressor. X
When the tyre pressure is correct, unscrew
the filler hose from the valve of the sealed
tyre.
Please note that tyre sealant may leak out
when unscrewing the filler hose.
X Screw the valve cap onto the tyre valve of the
sealed tyre. X
To remove the tyre sealant bottle from the
tyre inflation compressor, press together the
locking tabs on the yellow cap.
X Pull the tyre sealant bottle out of the tyre
inflation compressor.
The filler hose stays on the tyre sealant bottle. 298
