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.

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

using the trailer tow hitch. Operation

Where will I find...?
254 Vehicle tool kit, jack and spare
wheel*
The vehicle tool kit is located in a stowage
compartment underneath the floor of the
boot/luggage compartment. G
Risk of injury
The jack is designed only to raise and hold
the vehicle for a short time while a wheel
is being changed.
If you are carrying out work on the vehicle,
you must use stands.
Make sure that the jack is placed on a firm,
non-slip and level surface. Do not use
wooden blocks or similar objects as a jack
underlay. Otherwise, the jack will not be
able to achieve its load-bearing capacity
due to the restricted height.
Do not start the engine at any time while a
wheel is being changed.
Do not lie under the vehicle when it is being
supported by the jack. If you do not raise
the vehicle as described, it could slip off the
jack (e.g. if the engine is started or a door
or the boot lid/tailgate is opened or closed)
and you could be seriously injured. i
When using the jack, you should also
observe the safety notes in the "Flat tyre"
section (Y page 324).
