Driving ab
road 238 Driving on wet roads
If water has accumulated to a certain depth
on the road surface, there is a danger of aqua-
planing occurring, even if:
R you drive at low speeds
R the tyres have adequate tread depth
For this reason, do not drive in tyre ruts, and
brake carefully. Driving on flooded roads
If you have to drive on stretches of road on
which water has collected, please bear in
mind that:
R the maximum permitted still water depth is
25 cm.
R you should drive no faster than at walking
pace.
! Note that vehicles in front or oncoming
vehicles create waves. This could mean
that the maximum permitted water depth
is exceeded.
You must observe these notes, otherwise
damage may occur to the engine, electrics
or transmission. Driving abroad
Points to remember
An extensive Mercedes-Benz Service network
is also available in other countries. You can
obtain the relevant workshop directories
from any Mercedes-Benz Service Centre.
Only low-octane fuel is available in certain
countries.
You can find further information about fuel
grades on (Y page 218). Symmetrical dipped beam
If your journey takes you to countries where
vehicles are driven on the opposite side of the
road to the country in which the vehicle is
registered, your headlamps must be switched
to symmetrical dipped beam. Oncoming traf-
fic will be dazzled less. G
Risk of injury
Vehicles with xenon headlamps*:
Xenon bulbs are under high voltage. You
could get an electric shock and be seriously
or even fatally injured if you touch the elec-
tric contacts on xenon bulbs. Do not, there-
fore, remove the cover on xenon bulbs. Do not change xenon headlamps yourself,
but have them replaced at a qualified spe-
cialist workshop which has the necessary
specialist knowledge and tools to carry out
the work required.
Mercedes-Benz recommends that you use
a Mercedes-Benz Service Centre for this
purpose. In particular, work relevant to
safety or on safety-related systems must be
carried out at a qualified specialist work-
shop.

G
Risk of accident
When reversing the vehicle towards the
trailer, make sure there is nobody between
the trailer and the vehicle.
Couple and uncouple the trailer carefully. If
you do not couple the trailer to the towing
vehicle correctly, the trailer could become
detached.
Make sure that the following values are not
exceeded:
R The permitted trailer drawbar nose-
weight
R The permitted trailer load R
The permitted rear axle load of the towing
vehicle
R The maximum permissible gross vehicle
weight of both the towing vehicle and the
trailer
You will find the applicable permissible val-
ues which must not be exceeded in the
vehicle documents.
You will find the values approved by the
manufacturer on the vehicle identification
plates and those for the towing vehicle in
the “Technical data” section.
You will find installation dimensions and loads
in the "Technical data" section
(Y page 375).
The maximum permissible trailer drawbar
noseweight on the ball coupling is 76 kg
(Saloon) or 84 kg (Estate). However, the
actual noseweight must not exceed the value
given on the trailer coupling and trailer iden-
tification plates. The lowest weight applies.
! Use a noseweight as close as possible to
the maximum permissible noseweight. Do
not use a noseweight of less than 50 kg,
otherwise the trailer may come loose. Bear in mind that the payload and the rear
axle load are reduced by the actual nose-
weight.
i On vehicles without level control, the
height of the ball coupling will alter accord-
ing to the load placed on the vehicle. In this
case, you should use a trailer with a height-
adjustable drawbar.
Coupling up a trailer G
Risk of injury
Do not connect a trailer with an engaged
overrun brake. Otherwise, your hand could
become trapped between the bumper and
drawbar.
! Do not uncouple a trailer with overrun
brake between the bumper and drawbar,
otherwise your vehicle could be damaged
by the spring action of the overrun brake.
X Position the trailer level behind the vehicle.
X Couple up the trailer.
X Establish the electrical connection
between the vehicle and the trailer. Operation

Trailer towing
241
Driving tips In Germany, the maximum permitted speed
for vehicle/trailer combinations is 80 km/h.
!
A maximum speed of 80 km/h should not
be exceeded, even in countries where
higher speeds are permitted for vehicle/
trailer combinations.
When towing a trailer, your vehicle's handling
characteristics will be different in comparison
to when driving without a trailer.
The vehicle/trailer combination:
R is heavier
R is restricted in its acceleration and gradi-
ent-climbing capability
R has an increased braking distance
R is affected more by strong crosswinds
R demands more sensitive steering
R consumes more fuel
On long and steep downhill gradients you
must select a lower gear in good time, or in
vehicles with automatic transmission*, select
shift range 1,2or 3.
i This also applies if you have activated
cruise control, Distronic* or Speedtronic. This uses the braking effect of the engine and
you will not have to brake to such an extent
to maintain the same 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. G
Risk of accident
Never depress the brake pedal continu-
ously while the vehicle is in motion, e.g.
never cause the brakes to rub by applying
constant slight pedal pressure. This causes
the brake system to overheat, increases
the braking distance and can lead to the
brakes failing completely.
Driving tips
R Maintain a greater distance from the vehi-
cle in front than when driving without a
trailer.
R Avoid braking abruptly. If possible, brake
gently at first to allow the trailer to run on.
Then increase the braking force rapidly.
R The values given for gradient-climbing
capabilities from a standstill refer to sea
level. When driving in mountainous areas,
note that the power output of the engine, and consequently the vehicle's gradient-
climbing capability, decrease with increas-
ing altitude.
If the trailer swings from side to side:
X Do not accelerate.
X Do not counter-steer.
X Brake if necessary. G
Risk of accident
On no account should you attempt to draw
the vehicle/trailer combination out by
increasing speed. Folding in the ball coupling
i Fold in the ball coupling when you are not
using the trailer tow hitch. Operation

Care
245H
Environmental note
Dispose of empty packaging, cleaning
cloths and polishing wads in an environ-
mentally responsible manner.
! Do not affix:
R stickers
R films
R magnetic plates or similar items
to painted surfaces, otherwise you could
damage the paintwork. Vehicle care
! Do not park the vehicle for a long period
of time directly after cleaning, especially if
the wheels have just been cleaned with a
wheel cleaner. Wheel cleaners could cause
rapid corrosion of the brake discs and
brake pads/linings. After cleaning, park
the vehicle when it is at normal operating
temperature. Automatic car wash G
Risk of accident
The vehicle is braked when HOLD is activa-
ted. Therefore, deactivate HOLD before the
vehicle is washed in an automatic car wash.
You can wash the vehicle in an automatic car
wash from the very start.
! Do not use a touch-free automatic car
wash that uses chemical agents to wash
the vehicle.
Preferably use one with high-pressure jets for
prewashing.
If the vehicle is very dirty, prewash it before
cleaning it in an automatic car wash.
! Make sure that the automatic car wash is
suitable for the size of the vehicle. Fold in
the exterior mirrors before the vehicle is
washed. There is otherwise a risk of dam-
age to the exterior mirrors.
! Make sure the side windows are com-
pletely closed, the ventilation/heater
blower is fully turned off and the wind-
screen wiper switch is set to 0. The rain
sensor may otherwise be activated, for
instance, leading to inadvertent wiper sweeps being triggered. This could cause
damage to the vehicle.
After using an automatic car wash, wipe any
wax and drying agents off the windscreen and
the wiper blades. This will prevent smears and
reduce wiping noises caused by residue on
the windscreen.
High-pressure cleaners G
Risk of accident
Do not use high-pressure cleaners with cir-
cular-jet nozzles (dirt grinders) to clean
your vehicle or - especially - the tyres. You
could otherwise damage the tyres and
cause an accident.
! Observe the instructions issued by the
equipment manufacturer concerning the
distance to be maintained between the
nozzle of the high-pressure cleaner and the
vehicle (at least 30 cm).
Move the high-pressure cleaner nozzle
around when cleaning your vehicle.
Do not aim directly at any of the following:
R tyres
R door joint
R electrical components Operation

Risk of accident and injury
The operating safety of the vehicle could be impaired if service work is carried out incorrectly. There is a risk that you could lose control of
the vehicle and cause an accident. The safety systems may no longer be able to protect you or others as they are designed to do.
Always have maintenance work carried out at a qualified specialist workshop which has the necessary specialist knowledge and tools to
carry out the work required.
Mercedes-Benz recommends that you use a Mercedes-Benz Service Centre for this purpose.
