Driving instructions
Brakes
To help prevent brake disk corrosion after
driving on wet road surfaces (particularly
salted roads), it is advisable to brake the
vehicle with considerable force prior to
parking. The heat generated serves to dry
the brakes.
If your brake system is normally only sub-
jected to moderate loads, you should occa-
sionally test the effectiveness of the
brakes by applying above-normal braking
pressure at higher speeds. This will also
enhance the grip of the brake pads.Refer to the description of the Brake Assist
System (BAS or BAS Plus*) (
page 66).
Brake pad wear or a leak in the system may
be the reason for low brake fluid level in
the reservoir.
The brake fluid level in the reservoir may
be too low if the red brake warning lamp in
the instrument cluster comes on while the
engine is running and an acoustic warning
sounds (
page 569). Observe additional
messages in the multifunction display that
may appear (
page 580).
Have the brake system inspected
immediately. Contact an authorized
Mercedes-Benz Center.
Warning!G
After driving in heavy rain for some time
without applying the brakes or through wa-
ter deep enough to wet brake components,
the first braking action may be somewhat
reduced and increased pedal pressure may
be necessary to obtain expected braking
effect. 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 effec-
tiveness. It may not be possible to stop the
vehicle in sufficient time to avoid an
accident.
!Because the ESP® operates automatically,
the engine and ignition must be shut off
(SmartKey in starter switch position0 or1 or
KEYLESS-GO start/stop button* in position0
or1) when

the electronic parking brake is being tested
on a brake test dynamometer

the vehicle is being towed with the
front/rear axle raised
Active braking action through the ESP
® may oth-
erwise seriously damage the brake system.
Warning!G
Make sure not to endanger any other road
users when carrying out these braking ma-
neuvers.

531 Operation
Tires and wheels
Checking tire pressure electronically
with the Advanced Tire Pressure
Monitoring System (Advanced TPMS)The Advanced TPMS only functions on
wheels that are equipped with the proper
electronic sensors. It monitors the tire in-
flation pressure, as selected by the driver,
in all four tires. A warning is issued to alert
you to a decrease in pressure in one or
more of the tires.
Tire inflation pressure inquiries are made
using the multifunction display. The
present inflation pressures are displayed
only after a few minutes of travel time.
iThe Advanced Tire Pressure Monitoring
System (Advanced TPMS) is equipped with a
combination low tire pressure/TPMS malfunc-
tion telltale in the instrument cluster
(
page 576). Depending on how the telltale illu-
minates, it indicates a low tire inflation pressure
condition or a malfunction in the Advanced
TPMS system itself:

If the telltale illuminates continuously, one
or more of your tires is significantly underin-
flated. There is no malfunction in the
Advanced TPMS.

If the telltale flashes for 60 seconds and
then stays illuminated, the Advanced TPMS
system itself is not operating properly.

Lamps in instrument cluster
General information:
If any of the following lamps in the instru-
ment cluster fails to come on during the
bulb self-check when switching on the igni-
tion, have the respective bulb checked and
replaced if necessary.
ProblemPossible cause/consequenceSuggested solution
-The yellow Antilock
Brake System (ABS)
indicator lamp comes on
while the engine is run-
ning.The ABS has detected a malfunction and
has switched off. The BAS, ESP®, EBP and
PRE-SAFE® are also switched off (see mes-
sages in multifunction display).
The brake system is still functioning nor-
mally but without the ABS available.
If the ABS control unit is malfunctioning,
other systems such as Parktronic*,
DISTRONIC Plus*, navigation system, Park
Assist* and the automatic transmission
may also be malfunctioning.
Continue driving with added caution.
Wheels may lock during hard braking,
reducing steering capability.
Read and observe messages in the mul-
tifunction display (
page 580).
Have the system checked at an autho-
rized Mercedes-Benz Center as soon as
possible.
Failure to follow these instructions increas-
es the risk of an accident.

Vehicle status messages in the multi-
function display
Warning and malfunction messages ap-
pear in the multifunction display located in
the instrument cluster.
Certain warning and malfunction messag-
es are accompanied by an audible signal.
High-priority messages are shown in red
on the multifunction display. Messages of
lower priority are also shown in yellow or
white.
Address these messages accordingly and
follow the additional instructions given in
this Operator’s Manual.Certain messages of high priority cannot
be cleared from the multifunction display
using# or L on the multifunction
steering wheel (
page 257).
Other messages of high priority and mes-
sages of less immediate priority can be
cleared from the multifunction display
using# or L. They are then stored
in the vehicle status message memory
(
page 270). Remember that clearing a
message will only make the message dis-
appear. Clearing a message will not cor-
rect the condition that caused the
message to appear.
Warning!G
No messages will be displayed if either the
instrument cluster or the multifunction dis-
play is inoperative.
As a result, you will not be able to see infor-
mation about your driving conditions, such
as speed or outside temperature, warn-
ing/indicator lamps, malfunction/warning
messages or the failure of any systems.
Driving characteristics may be impaired.
If you must continue to drive, please do so
with added caution. Contact an authorized
Mercedes-Benz Center as soon as possible.

Front pass. airbag
disabled
See Oper. ManualFront passenger front air bag is
deactivated while driving even
though an adult or someone
larger than a small individual is
occupying the front passenger
seat. Forces acting on the seat
may make the system sense a
decrease in weight.Stop the vehicle in a safe location as soon as possible and check the front
passenger seat for the following:
Switch off the ignition (page 336).
Have the front passenger vacate the seat and exit the vehicle.
Adjust the seat in a height position (page 339).
Make sure that no objects which apply forces to the seat are present (e.g.
objects such as books, briefcases etc. lodged underneath, behind or
around the seat). Such forces may cause the system to sense that an oc-
cupant of a lesser weight than actually present is on the front passenger
seat.
Keep the seat unoccupied, close the passenger door and switch on the ig-
nition (
page 336).

Front pass. airbag
disabled
See Oper. ManualWith the seat unoccupied and the ignition switched on (page 336),

the 59indicator lamp right of the instrument cluster should
illuminate and remain illuminated, indicating that the OCS (
page 47)
has deactivated the air bag.

the message “Front passenger airbag enabled See Oper. Manual” or the
message “Front passenger airbag disabled See Oper. Manual” should not
appear in the multifunction display at any time the seat is unoccupied.
Wait at least 60 seconds for the system to complete the necessary check
cycles and to make sure neither message appears in the multifunction dis-
play.
If above conditions are met, you can occupy the front passenger seat again.
Depending on the front passenger classification sensed by the OCS
(
page 47), the59indicator lamp will remain illuminated or go
out.
If above conditions are not met, the system is not working properly. Have the
system checked as soon as possible by an authorized Mercedes-Benz Center.
Warning!G
If the 59indicator lamp re-
mains illuminated with an adult occupant on
the front passenger seat even after
performing the above corrective steps, do
not have any passenger use the front pas-
senger seat until the system has been re-
paired.

enabled
See Oper. ManualFront passenger front air bag is
activated while driving even
though a child, small individual,
or object below the system’s
weight threshold is on the front
passenger seat, or the front pas-
senger seat is empty. Objects
on the seat or forces acting on
the seat may make the system
sense supplemental weight.Stop the vehicle in a safe location as soon as possible and check the front
passenger seat for the following:
Switch off the ignition (page 336).
Remove child and child restraint from front passenger seat and properly
secure the child in rear seat employing the child restraint if necessary.
Remove any other items from on and around the front passenger seat and
make sure the storage bag on the back of the front passenger seat is emp-
ty.
Make sure that 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.
