The maximum permissible speed for vehicle/
trailer combinations depends on the type of
trailer. Before beginnin gthe journey, check
the trailer's document stosee what the max-
imum permitted speed is. Observe the legally
prescribed maximum speed in the relevant
country.
For certain Mercedes-Benz vehicles, the max-
imum permissible rear axle load is increased
when towing atrailer. See the "Technical
data" section to find out whether this applies to your vehicle (Y page 484). If you utilise any
of the added maximum rear axle load when
towing atrailer, the vehicle/trailer combina-
tion may not exceed amaximum speed of
100 km/hf or reasons concerning the oper-
ating permit. This also applie sincountrie sin
which the permissible maximu mspee dfor
vehicle/trailer combinations is above
100 km/h.
When towing atrailer, you rvehicle's handling
characteristics wil lbedifferent in comparison
to whe ndriving without atrailer and it will
consume more fuel.
Change into alower gea ringood time on long
and steep downhill gradients.
i This also applie
sifyou have activated
cruis econtrol, SPEEDTRONIC or
DISTRONIC PLUS.
This wil luse the braking effect of the engine,
so less braking wil lberequired to maintain
vehicle speed. This relieves the loa donthe
brake system and prevents the brake sfrom
overheating and wearing too quickly. If you
need additiona lbraking, depress the brake
pedal repeatedl yrather than continuously.
Driving tips If the trailer swings from side to side:
X Do not accelerate.
X Do not countersteer.
X Brake if necessary. R
Maintain agreater distance to the vehicle in
front than whe ndriving without atrailer.
R Avoid braking abruptly .Ifpossible ,brake
gently at first to allow the trailer to run on.
Then, increase the braking force rapidly.
R The values give nfor gradient-climbing
capabilities from astandstil lrefer to sea
level. When driving in mountainous areas,
note that the power outpu tofthe engine,
and consequently the vehicle's gradient-
climbing capability, decrease with increas-
ing altitude. Foldin
gout the ball coupling G
WARNING
If the bal lcoupling is not correctly engaged,
the trailer can detach .There is arisk of an
accident.
Always engag ethe bal lcoupling as described. G
WARNING
If you release the bal lcoupling or it does not
engag ecorrectly whe nfolding in, it wil lswing
out. Withi npivoting range of the bal lcoupling,
there is an increased risk of an accident and
injury.
Only release the bal lcoupling if the pivoting
range is unobstructed. Always make sure that the bal lcoupling engages whe nfolding in. Saloon
Before you can tow
atrailer with you rvehicle,
you must fold out the bal lcoupling. 268
