WARNING Risk of accident due tothe
brake sy stem overheating
If yo u lea veyour foot on the brake pedal
when driving, the brake sy stem may over‐
heat.
This increases the braking dis tance and the
brake sy stem may evenfa il.
#Ne ver use the brake pedal as a foot re st.
#Do not depress the brake pedal and the
accelerator pedal at the same time
while driving.
* NO
TEWearing out the brake linings by
continuously dep ressing the brake pedal
#Do not depress the brake pedal contin‐
uously whilst driving.
#To use the braking ef fect of the engine,
shift toa lo werge ar in good time.
* NO
TEDama getothe driv etra in and the
engine when pulling away
#Do not warm upthe engine when the
ve hicle is stationar y.Pull away immedi‐
atel y.
#Avoid high engine speeds and driving at
full thro ttle until the engine has reached
operating temp erature.
#Do not allow the wheels tospin.
* NO
TEDama getothe catalytic con verter
due tonon-combu sted fuel
The engine is not running smoot hly and is
misfiring.
Non-combus ted fuel may get into the cata‐
lytic con verter.
#Only depress the accelera tor pedal
slightl y.
#Have the cause rectified immediately at
a qu alified specialist workshop.
Limited braking ef fect on salt-treate dro ads:
Rdue tosalt build-up on the brake discs and
brake lining, the braking dis tance can
increase conside rably or result in braking
only on one side.
Rmaintain a much greater dis tance totheve hi‐
cle in front.
To preve nt salt build-up:
Rbrake occasionally while paying attention to
th e tra ffic conditions.
Rcarefully depress the brake pedal at the end
of the journey and when starting the next
journe y.

Speed control cruise control
Function of cruise control
Cruise cont rol accelerates and brakes theve hi‐
cle automatically in order tomaintain a pr evi‐
ously stored speed.
If yo u accelerate toove rtake, forex ample, the
st ored speed is not dele ted. If youre mo veyour
fo ot from the accelerator pedal af terove rtaking,
cruise control will resume speed regulation back
to thestored speed.
Yo u can operate cruise cont rol with the cruise
control le ver.
If yo ufa ilto adapt your dr ivingst yle, cruise con‐
trol can neither reduce therisk of an accident
nor override the la wsof ph ysics. It cannot take
into account road, weather or traf fic conditions.
Cruise control is only an aid. You are responsible
fo rth e dis tance totheve hicle in front, forve hi‐
cle speed, for braking in good time and forst ay ‐
ing in lane.
Sy stem limitations
Cruise control may be unable tomaintain the
st ored speed on uphill gradients. The stored
speed is resumed when the gradient evens out. Change into a lo
werge ar in good time on long
and steep downhill gradients. Take particular
no te ofthis when driving a laden vehicle. By
doing so, you will make use of the braking ef fect
of the engine. This relie vesth e load on the brake
sy stem and pr events the brakes from overheat‐
ing and
wearin
g tooqu ickl y.
Do not use cruise control in thefo llowing situa‐
tions:
RIn traf fic situations whi chrequ ire frequent
ch anges of speed, e.g. in heavy traf fic, on
winding roads
ROn slippery roads. Accelerating can cause
th e drive wheels tolose traction and the
ve hicle could then skid
RWhen visibility is poor

WARNING Risk of burn s from hot com‐
ponent parts in the engine compartment
Cer tain component parts in the engine com‐
partment can be very hot, e.g. the engine,
th e cooler and parts of theex haust sy stem.
#Let the engine cool down and only

WARNING Danger of burn s when open‐
ing the engine hood
If yo u open the engine hood when the engine
has overheated or during a fire inthe engine
compartment, you could come into contact
with hot gases or other escaping operating
fl uids.
#Before opening the engine hood, allow
th e engine tocool down.
#Intheeve nt of a fire inthe engine com‐
partment, keep the engine hood closed

TEOverheating at high outside tem‐
peratures
If an inappro priate coolant is used, the
engine cooling sy stem is not suf ficiently pro‐
te cted against overheating and cor rosion at
high outside temp eratures.
#Alw ays use coolant appr ovedby

#Obser vethe instructions in the
Mercedes-Benz Specifications for Oper‐
ating Fluids 310.1.
Ha ve the coolant regularly changed at a qualified
specialist workshop.
The proportion of cor rosion inhibitor/antifreeze
concentrate in the engine cooling sy stem should
be:
RA minimum of 50% (antifreeze pr otection
down toappr oximately -35 °F (-37 °C)).
