All checks and service work on the brake system should 
be carried out by an authorized Mercedes-Benz Center.
Install only brake pads and brake fluid recommended by 
Mercedes-Benz.
Caution!
When driving down long and steep grades, relieve the 
load on the brakes by shifting into a lower gear to use 
the engine’s braking power. This helps prevent 
overheating of the brakes and reduces brake pad wear.
After hard braking, it is advisable to drive on for some 
time, rather than immediately parking, so the air stream 
will cool down the brakes faster.
Driving off
Apply the service brakes to test them briefly after 
driving off. Perform this procedure only when the road 
is clear of other traffic.
Warm up the engine smoothly. Do not place full load on 
the engine until the operating temperature has been 
reached.
When starting off on a slippery surface, do not allow one 
drive wheel to spin for an extended period with the ESP 
switched off. Doing so may cause serious damage to the 
drive train which is not covered by the Mercedes-Benz 
Limited Warranty.
Wa r n i n g !
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.

Winter driving
Have your vehicle winterized at your authorized 
Mercedes-Benz Center before the onset of winter.
• Change the engine oil if the engine contains an oil 
which is not approved for winter operation. For 
viscosity (SAE / CCMC class) and filling quantity, 
seepage379.
• Check engine coolant anticorrosion / antifreeze 
concentration.
• Additive for the windshield washer and headlamp 
cleaning system: Add MB Concentrate “S” to a 
premixed windshield washer solvent / antifreeze 
which is formulated for below freezing 
temperatures, see page 320.
• Test battery: Battery capacity drops with decreasing 
ambient temperature. A well charged battery helps 
to ensure that the engine can be started, even at low 
ambient temperatures.
• Tires: We recommend M+S rated radial-ply tires on 
all four wheels for the winter season. Observe 
permissible maximum speed for M+S rated 
radial-ply tires and the legal speed limit. Note:
In winter operation, the maximum effectiveness of the 
antilock brake system (ABS) and electronic stability 
program (ESP) can only be achieved with M+S rated 
radial-ply tires and / or snow chains recommended by 
Mercedes-Benz. Snow chains maximize performance.

Canceling
To cancel the cruise control, briefly push lever to 
position 3.
When you step on the brake pedal or the vehicle 
speed drops below approximately 20 mph 
(30 km / h), for example when driving upgrade, the 
cruise control will be canceled.
If the cruise control cancels by itself and remains 
inoperative until the engine is restarted, have the 
system checked at your authorized Mercedes-Benz 
Center as soon as possible. 4
Resume
If the lever is briefly pushed to position 4 when 
driving at a speed exceeding approximately 20 mph
(30 km / h), the vehicle resumes the speed which 
was set prior to the cancellation of the cruise 
control.
The last memorized speed is canceled when the 
electronic key in the starter switch is turned to 
position 1 or 0.
Important!
Moving gear selector lever to position “N” switches the 
cruise control off.

Brake assist system (BAS)
The BAS is designed to maximize the vehicle’s braking 
capability during emergency braking maneuvers by 
having maximum power boost applied to the brakes 
more quickly in emergency braking conditions than 
might otherwise be afforded solely by the driver’s 
braking style. This can help reduce braking distances 
over what ordinary driving and braking style might do. 
The BAS complements the antilock brake system (ABS).
Applying the brakes very quickly results in maximum 
BAS assistance.
To receive the benefit of the system you must apply 
continuous full braking power during the stopping 
sequence. Do not reduce brake pedal pressure.
Once the brake pedal is released, the BAS is deactivated.
If the BAS warning message is displayed, a malfunction 
has been detected in the system. The brake system 
functions in the usual manner, but without BAS.
With the ABS malfunctioning, the BAS is also switched 
off.
If a BAS warning message is displayed, have the BAS 
checked at your authorized Mercedes-Benz Center as 
soon as possible.
Wa r n i n g !
BAS cannot prevent the natural laws of physics 
from acting on the vehicle, nor can it increase 
braking efficiency beyond that afforded by the 
condition of the vehicle brakes and tires or the 
traction afforded. The BAS cannot prevent 
accidents, including those resulting from excessive 
speed in turns, following another vehicle too 
closely, or aquaplaning. Only a safe, attentive, and 
skillful driver can prevent accidents. The 
capabilities of a BAS equipped vehicle must never 
be exploited in a reckless or dangerous manner 
which could jeopardize the user’s safety or the 
safety of others.

ABS control
The ABS malfunction indicator lamp
- in the 
instrument cluster comes on with the electronic key in 
starter switch position 2 and should go out with the 
engine running.
When the ABS malfunction indicator lamp in the 
instrument cluster comes on while the engine is 
running, it indicates that the ABS has detected a 
malfunction and has switched off. In this case, the brake 
system functions in the usual manner, but without 
antilock assistance.
For ABS malfunction indicator lamp, see page 287.
With the ABS malfunctioning, the BAS and ESP are also 
switched off. Both malfunction indicator lamps come on 
with the engine running.
If the charging voltage falls below 10 volts, the 
malfunction indicator lamp comes on and the ABS is 
switched off. When the voltage is above this value again, 
the malfunction indicator lamp should go out and the 
ABS is operational. If the ABS malfunction indicator lamp stays illuminated, 
have the system checked at your authorized 
Mercedes-Benz Center as soon as possible.
Note:
To alert following vehicles to slippery road conditions 
you discover, operate your hazard warning flashers as 
appropriate.

Notes:
The yellow ESP warning lamp
v in the speedometer 
dial comes on with the electronic key in starter switch 
position 2. It should go out with the engine running.
If the ESP warning message is displayed, a malfunction 
has been detected in the system. Only partial engine 
output will be available.
Have the ESP checked at your authorized 
Mercedes-Benz Center as soon as possible.
For ESP warning message, see page 288.
With the ABS malfunctioning, the ESP is also switched 
off.
Driving the vehicle with varied size tires will cause the 
wheels to rotate at different speeds, therefore the ESP 
may activate (yellow ESP warning lamp in speedometer 
dial comes on). For this reason, all wheels, including the 
spare wheel, must have the same tire size.  When testing the parking brake on a brake test 
dynamometer, the engine must be shut off. Otherwise, 
the ESP will immediately be engaged and will apply the 
rear wheel brakes. 
In winter operation, the maximum effectiveness of the 
ESP is only achieved with Mercedes-Benz recommended 
M+S rated radial-ply tires and / or snow chains.
Synchronizing ESP
If the power supply was interrupted (battery 
disconnected or empty), the ESP warning message may 
be displayed with the engine running.
Turn steering wheel completely to the left and then to 
the right. The ESP warning message should go out.

What you should know at the gas station
Fuel supply Open flap by pushing near front (arrow). Turn fuel cap 
to the left and hold on to it until possible pressure in 
tank has been released, then remove cap. Failure to 
remove slowly could result in personal injury.
See page 354 for manual release of fuel filler flap.
Fuel
To prevent fuel vapors from escaping into open air, fully 
insert filler nozzle unit.
Only fill fuel tank until the filler nozzle unit cuts out 
– do not top up or overfill.
Leaving the engine running and the fuel cap open can 
cause the “CHECK ENGINE” lamp to illuminate, see 
page 283 for notes on the “CHECK ENGINE” lamp.
Wa r n i n g !
Gasoline is highly flammable and poisonous. It 
burns violently and can cause serious injury. 
Whenever you are around gasoline, avoid inhaling 
fumes and skin contact, extinguish all smoking 
materials. Never allow sparks, flame or smoking 
materials near gasoline!
Wa r n i n g !
Overfilling of fuel tank may result in creating 
pressure in the system which could cause a gas 
discharge such as the gas spraying back out upon 
removing the filler nozzle which could cause 
personal injury.
