It can also result in the brakes overheating,
thereby significantly reducing their
effectiveness. It may not be possible to stop
the vehicle in sufficient time to avoid an
accident.
After hard braking, it is advisable to drive on
for
some time, rather than immediately park,
so that the air stream will cool down the
brakes faster.
Wet roads G
Warning!
After driving in heavy rain for some time
without
applying the brakes or through water
deep enough to wet brake components, the
first braking action may be somewhat
reduced and increased pedal pressure may be
necessary to obtain expected brake effect.
Maintain a safe distance from vehicles in
front.
To help prevent brake disk corrosion after
driving on wet or salt-covered roads, it is
advisable to brake the vehicle with
considerable force prior to parking. The heat
generated serves to dry the brakes.
Salt-covered roads G
Warning!
A layer of salt on the brake discs and the brake
linings may cause a delay in the braking
effect, resulting in a significantly increased
braking distance, which could lead to an
accident.
To avoid this danger, you should:
R occasionally brake carefully when you are
driving on salt-covered roads, so that any
layer of salt that may have built up on the
brake discs and the brake linings is removed without putting other road users
at risk
R maintain a greater distance to the vehicle
ahead and drive with 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 disc
Brake service !
The brake fluid level in the reservoir may
be

too low if the brake warning lamp in the
instrument cluster comes on and an
acoustic warning sounds although the
parking brake is released. Observe
additional messages in the multifunction
display that may appear.
Brake pad wear or a leak in the system may
be the reason for low brake fluid in the
reservoir.
Have the brake system inspected
immediately. Contact an authorized
Mercedes-Benz Center.
All checks and service work on the brake
system should be carried out by qualified
technicians only. Contact an authorized
Mercedes-Benz Center.
Only install brake pads and use brake fluid
recommended by Mercedes-Benz. G
Warning!
If other than recommended brake pads are
installed, or other than recommended brake
fluid is used, the braking properties of the
vehicle

can be degraded to an extent that safe
braking is substantially impaired. This could
result in an accident.
! Because the ESP ®
operates
automatically, the engine and ignition must
be shut off (SmartKey in starter switch
position 0 or 1 or KEYLESS-GO start/stop
button in position 0 or 1) when the parking
brake is being tested on a brake test Driving instructions

child restraint if necessary.
X Remove any other items from on and around the front

of the front passenger seat is empty.
X Make sure no objects which apply forces to the seat are
present

(e.g. objects such as books, briefcases etc. lodged
behind or around the seat, head restraints pushing against
roof etc.). The system may recognize such forces as
supplemental weight and sense that an occupant on the
front passenger seat is of a greater weight than actually
present.
X Keep the seat unoccupied, close the front passenger door

If above conditions are met, you can occupy the front
passenger seat again. Depending on the front passenger
classification sensed by the OCS, the 04
indicator lamp will remain illuminated or go out.
If above conditions are not met, the system is not working

During severe operation conditions and stop-and-go city
traffic, the coolant temperature may rise close to 248‡
(120†). G
Warning!
Driving when your engine is overheated can cause some fluids which may have leaked into the
engine compartment to catch fire. You could be seriously burned.
Steam
from an overheated engine can cause serious burns which can occur just by opening the
engine hood. Stay away from the engine if you see or hear steam coming from it.
Stop the vehicle in a safe location away from other traffic. Turn off the engine, get out of the
vehicle and do not stand near the vehicle until the engine has cooled down.
! The engine should not be operated with the coolant temperature above 248‡ (120†).
Doing so may cause serious damage which is not covered by the Mercedes-Benz Limited
Warranty. 244
