Important safety notes
G
Risk of accident
Only remove the key from the ignition lock
when the vehicle is stationary, as you cannot
steer the vehicle when the key is removed.
Never leave children unsupervised in the vehi-
cle. They could release the parking brake. This
could lead to aserious or fatal accident. G
Risk of fire
Make sure that the exhaust system does not
under any circumstances com einto contact
with easily ignitable material such as dry grass
or petrol .Otherwise, the flammable material
may ignite and set the vehicle on fire.
To ensure that the vehicle is secured against
rolling away unintentionally:
R the parking brake must be appl ied.
R on vehicles wit hmanual transmission,
engage first gear or reverse gear.
R on vehicles with automatic transmission,
the transmissio nmust be in position Pand
the key must be removed from the ignition
lock.
R on steep uphill or downhill gradients, turn
the front wheel stowards the kerb. Parking brake

Heav
yand light loads G
Risk of accident
Never depr esst he brake pedal continuously
while the vehicle is in motion ,e.g. never cause
the brakes to rub by applying cons tant slight
pedal pressure. Thi scauses the brake system
to overheat, increases the braking distance
and can lead to the brakes failing completely.
If the brakes have been subjected to aheavy
load, do not stop the vehicle immediately ,but
drive on for ashort while. This allow sthe air-
flo wtoc ool the brakes mor equickly.
If the brakes have been used only moderately,
you should occasionally test their effective-
ness. To do this, brake more firmly from a
higher speed. This improves the grip of the
brakes.
Wet roads If driving in heavy rain for
aprolonged period
of time without braking, there may be a
delayed reaction from th ebrake swhen brak-
ing for the first time. This ma yalso occur after
the vehicle has been washed.
You have to depress the brake pedal more
firmly. Maintain agreater distance from the
vehicl einfront.
After driving on awet road or havin gthe vehi-
cle washed, brake firml ywhile paying atten-
tion to the traffic conditions. This will warm
up the brake discs, thereby drying them more
quickly and protecting them against corro-
sion.
Limited braking perfo rmance on salt
treated roads G
Risk of accident
The layer of salt on the brake discs and the
brake pads/linings may cause adelay in the
braking effect ,resultin ginas ignifican tlyl on-
ger brakin gdistance, which could lead to an
accident.
To avoid this danger, you should: R
occasionally brake carefully, without put-
ting other road users at risk, when you are
drivin gons alted roads. This helps to
remove any salt that may have started to
build up on the brake discs and the brake
pads/linings.
R maintain agreater distance to th evehicle
ahead and driv ewith particular care.
R carefully apply the brakes at the end of a
trip and immediately after commencing a
new trip, so that salt residues are removed
from the brake discs.
New brake pads/linin gs G
Risk of accident
New brake pads/lining sonly reach thei ropti-
mum braking effect after severa lhundred kil-
ometres of driving. Before this optimum brak-
ing effect is reached, you should compensate
for the reduced braking effect by applying
greater pressure when braking. This also
applies after the brake discs or the brake
pads/lining shave been replaced.
For safety reasons, Mercedes-Benz recom-
mends that you only have brake pads/linings
fitted to your vehicle which have been
approved for Mercedes-Benz vehicles or
which correspond to an equivalent quality
standard. Brake pads/lining swhich hav enot
been approved for Mercedes-Benz vehicles or
which ar enot of an equivalent quality could
affect your vehicle' soperating safety. Ty
re traction G
Risk of accident
Whil ethe vehicle can be fully con trolled at a
cer tain speed on dry roads, you must reduce
your speed on wet or icy roads to achieve the
same road safety. Otherwise, you could cause
an accident.
Pay particular attention to the road conditions
at temperatures around freezin gpoint. Driving tips

When you are driving back on the same side

Cruise control
Import ants afety notes Cruise control maintain
saconstant road
speed for you. It brakes automatically in order
to avoid exceeding the set speed. On long and
steep downhil lgradients ,especially if the
vehicle is laden or towing atrailer, yo umust
shift to alower gear in good tim eorselect
shift range 1,2or 3on vehicles with auto-
matic transmission. By doing so, you will
mak euse of the brakin geffect of th eengine,
which relieves the load on the brake system and prevents the brakes from overheating
and wearing too quickly. G
Risk of accident
Do not change down for additional engine
braking on aslippery road surface. This could
cause the drive wheels to lose their grip and
the vehicle could skid.
Use cruise control only if road and traffic con-
ditions make it appropriate to maintain a
steady speed for aprolonged period. Yo ucan
store any road spee dabove 30 km/h. G
Risk of accident
Cruise control cannot take account of road
and traffic conditions.
Always pay atten tion to traffic conditions
even when cruise control is activated.
Cruise control is only an aid designed to assist
driving. You are responsible for the vehicle's
speed and for brakin gingood time. G
Risk of accident
Do not use cruise control:
R in road and traffic condition swhich do not
allow you to maintain aconstant speed (e.g.
heavy traffic or winding roads). You could
otherwise cause an accident.
R on slippery roads. Brakin goraccelerating
coul dcause the drive wheels to lose trac-
tion and the vehicle could then skid.
R when there is poor visibility, e.g. due to fog,
heavy rain or snow
