80 Safety and SecurityDriving safety systemsABS
The Antilock Brake System (ABS) regulates 
the brake pressure so that the wheels do 
not lock during braking. This allows you to 
maintain the ability to steer your vehicle.
The ABS is functional above a speed of 
approximately 5 mph (8 km/h) indepen-
dent of road surface conditions.
On slippery road surfaces, the ABS will re-
spond even to light brake pressure. The - indicator lamp in the instrument 
cluster comes on when you switch on igni-
tion. It goes out when the engine is run-
ning.
Braking
If the ABS activates during braking, the 
ABS/ESP warning lamp v in the instru-
ment cluster dial flashes. Because of the 
SBC brake system, you will not feel any 
pulsation in the brake pedal.
Keep firm and steady pressure on the 
brake pedal.
Continuous, steady brake pedal pressure 
yields the advantages provided by the ABS, 
namely braking power and the ability to 
steer the vehicle.The ABS/ESP warning lamp v flashes 
whenever the ABS is activated which can 
be an indication of hazardous road condi-
tions and functions as a reminder to take 
extra care while driving.
Emergency brake maneuver
Keep continuous, full pressure on the 
brake pedal.
Warning!
G
Do not pump the brake pedal. Use firm, 
steady brake pedal pressure instead. Pump-
ing the brake pedal defeats the purpose of 
the ABS and significantly reduces braking 
effectiveness.
Warning!
G
When the ABS is malfunctioning, the BAS 
and the ESP are also switched off.
When the ABS is malfunctioning, the wheels 
may lock during hard braking, reducing 
steering capability and extending the brak-
ing distance.

82 Safety and SecurityDriving safety systemsESP
The Electronic Stability Program (ESP) is 
operational as soon as the engine is run-
ning and monitors the vehicle's traction 
(force of adhesive friction between the 
tires and the road surface) and handling.
The ESP recognizes when a wheel is spin-
ning or if the vehicle starts to skid. By ap-
plying brakes to the appropriate wheel and 
by limiting engine output, the ESP works to 
stabilize the vehicle. The ESP is especially 
useful while driving off and on wet or slip-
pery road surfaces. The ESP also stabilizes 
the vehicle during braking maneuvers.
The ABS/ESP warning lamp v in the in-
strument cluster (
page 25) flashes when 
the ESP is engaged.
The ABS/ESP warning lamp v in the 
instrument cluster comes on when you 
switch on the ignition. It goes out when the 
engine is running.
Warning!
G
Never switch off the ESP when you see the 
ABS/ESP warning lamp v flashing in the 
instrument cluster. In this case proceed as 
follows:
While driving off, apply as little throttle 
as possible.
While driving, ease up on the accelera-
tor.
Adapt your speed and driving style to 
the prevailing road conditions.
Failure to observe these guidelines could 
cause the vehicle to skid.
The ESP cannot prevent accidents resulting 
from excessive speed.
Warning!
G
The ESP cannot prevent the natural laws of 
physics from acting on the vehicle, nor can 
it increase the traction afforded. The ESP 
cannot prevent accidents, including those 
resulting from excessive speed in turns, or 
hydroplaning. Only a safe, attentive, and 
skillful driver can prevent accidents. The ca-
pabilities of an ESP equipped vehicle must 
never be exploited in a reckless or danger-
ous manner which could jeopardize the us-
er’s safety or the safety of others.iThe ESP will only function properly if 
you use wheels of the recommended 
tire size (
page 422).

Press ESP switch1 until the ABS/ESP 
warning lamp v in the instrument 
cluster comes on.
ESP is deactivated.Switching on the ESP
Press ESP switch1. 
The ABS/ESP warning lamp v in 
the instrument cluster goes out.
You are now again in normal driving 
mode with the ESP switched on.
Warning!
G
When the  ABS/ESP warning lampv is 
illuminated continuously, the ESP is 
switched off. 
Adapt your speed and driving to the prevail-
ing road conditions and to the non-operating 
status of the ESP.!Avoid spinning of a drive wheel for an 
extended period with the ESP switched 
off. This may cause serious damage to 
the drivetrain which is not covered by 
the Mercedes-Benz Limited Warranty.
!Turn on the ESP immediately if the 
aforementioned circumstances do not 
apply anymore.

Warning
G
Driving when your engine is badly over-
heated can cause some fluids which 
may have leaked into the engine com-
partment to catch fire. You could be se-
riously burned.
Steam from an overheated engine can 
cause serious burns an can occur just by 
opening the hood. Stay away from the 
engine if you see or hear steam coming 
from it.
Turn off the engine, get out of the vehicle 
and do not stand near the vehicle until the 
engine has cooled down.

stop-and-go traffic, the coolant tempera-
ture may rise close to 248°F (120°C).
The engine should not be operated with 
the coolant temperature above 248°F 
(120°C). Doing so may cause serious en-
gine damage which is not covered by the 
Mercedes-Benz Limited Warranty.

The red marking on the tachometer de-
notes excessive engine speed.
To help protect the engine, the fuel supply 
is interrupted if the engine is operated 
within the red marking.
!Excessive coolant temperature triggers 
the coolant temperature warning lamp 
(page 352) and a warning in the

Outside temperature indicator
The outside temperature is displayed in 
the right multifunction display 
(page 24). For information on how to se-
lect the unit of the displayed temperature, 
i.e. degrees Celsius (°C) or degrees Fahr-
enheit (°F), see “Selecting temperature 
display mode” (
page 148).The temperature sensor is located in the 
front bumper area. Due to its location, the 
sensor can be affected by road or engine 
heat during idling or slow driving. There-
fore, the accuracy of the displayed temper-
ature can only be verified by comparison to 
a thermometer placed next the sensor, not 
by comparison to external displays, e.g. 
bank signs, etc.
When moving the vehicle into colder ambi-
ent temperatures (e.g. when leaving your 
garage), you will notice a delay before the 
lower temperature is displayed. 
A delay also occurs when ambient temper-
atures rise. This prevents inaccurate tem-
perature indications caused by heat 
radiated from the engine during idling or 
slow driving.
Warning!
G
The outside temperature indicator is not de-
signed to serve as an ice-warning device and 
is therefore unsuitable for that purpose.
Indicated temperatures just above the freez-
ing point do not guarantee that the road sur-
face is free of ice. The road may still be icy, 
especially in wooded areas or on bridges.
