Power assistance
Brakes Excessive use of road salt and other snow melting
chemicals spread on roads during the winter months
may cause a build up of moisture or residue to form on
the braking components. This build up or residue could
cause light corrosion of the braking components if the
vehicle is parked with the brakes cold. Apply steady and
even braking pressure when stopping the vehicle to
warm up and dry the brake components.
Important!
Please pay attention to the function of the brake assist
system (BAS), see page 271.
The condition of the parking brake system is checked
each time the vehicle is in the shop for the required
maintenance service.
If the parking brake is released and the brake warning
lamp in the instrument cluster stays on, the brake fluid
level in the reservoir is too low.
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 at an authorized
Mercedes-Benz Center immediately.
Wa r n i n g !
When the engine is not running, the brake and
steering systems are without power assistance.
Under these circumstances, a much greater effort is
necessary to stop or steer the vehicle.Wa r n i n g !
After driving in heavy rain for some time without
applying the brakes or through water deep enough
to wet brake components or salty road conditions,
the first braking action may be somewhat reduced
and increased pedal pressure may be necessary to
obtain expected braking effect. Be sure to maintain
a safe distance from vehicles in front.Resting your foot on the brake pedal will cause
excessive and premature wear of the brake pads.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.

Electronic stability program (ESP) — warning lamp The yellow ESP warning lamp in the
speedometer dial comes on with the
electronic key in starter switch position 2.
It should go out with engine running.
If the ESP malfunction indicator lamp remains
illuminated with the engine running, a malfunction has
been detected in the system. Pressing the accelerator
pedal will require greater effort. Only partial engine
output will be available.
See electronic stability program (ESP) on page 274 if the
warning lamp lights up or flashes when the vehicle is
moving. Seat belt nonusage warning lamp
With the electronic key in starter switch
position 2, the seat belt nonusage warning
lamp comes on, and a warning sounds for a
short time if the drivers seat belt is not fastened.
After starting the engine, the seat belt nonusage
warning lamp blinks for a brief period to remind the
driver and passengers to fasten seat belts.
