78 Safety and SecurityDriving safety systemsBraking
At the instant one of the wheels is about to 
lock up, a slight pulsation can be felt in the 
brake pedal, indicating that the ABS is in 
the regulating mode.
Keep firm and steady pressure on the 
brake pedal while experiencing the 
pulsation.
Continuous steady brake pedal pressure 
yields the advantages provided by the ABS, 
namely braking power and ability to steer 
the vehicle.
The pulsating brake pedal can be an 
indication of hazardous road conditions 
and functions as a reminder to take extra 
care while driving.Emergency brake maneuver
Keep continuous full pressure on the 
brake pedal.
For more information, see “Practical hints” 
(
page 302) and (
page 310).
BAS
The Brake Assist System (BAS) operates in 
emergency situations. If you apply the 
brakes very quickly, the BAS automatically 
provides full brake boost, thereby poten-
tially reducing the braking distance. Apply 
continuous full braking pressure until the 
emergency braking situation is over. The 
ABS will prevent the wheels from locking.
When you release the brake pedal, the 
brakes function again as normal. The BAS 
is then deactivated.
Warning!
G
The ABS cannot prevent the natural laws of 
physics from acting on the vehicle, nor can 
it increase braking or steering efficiency 
beyond that afforded by the condition of the 
vehicle brakes and tires or the traction af-
forded. The ABS cannot prevent accidents, 
including those resulting from excessive 
speed in turns, following another vehicle too 
closely, or hydroplaning. Only a safe, atten-
tive, and skillful driver can prevent acci-
dents. The capabilities of an ABS equipped 
vehicle must never be exploited in a reck-
less or dangerous manner which could jeop-
ardize the user’s safety or the safety of 
others.
Warning!
G
If the BAS is malfunctioning, the brake sys-
tem is still functioning normally, but without 
the additional brake boost available that 
BAS would normally provide in an emergen-
cy braking maneuver. Therefore, the braking 
distance may increase.

Driving safety systems
When you switch off the ESP
the ESP does not stabilize the vehicle
the engine output is not limited, which 
allows the drive wheels to spin and 
thus cut into surfaces for better grip
the traction control will still brake a 
spinning wheel
the ESP continues to operate when you 
are brakingThe switch is located on the center 
console.
1ESP switch (off/on)
Press switch1.
The ESP warning lampv in the 
speedometer comes on.
The ESP is deactivated.
Switching on the ESP
Press switch1 again.
The ESP warning lampv in the 
speedometer goes out.
You are now again in normal driving 
mode with the ESP switched on.
iWhen the ESP is switched off and one 
or more drive wheels are spinning, the 
ESP warning lampv in the speed-
ometer flashes. However, the ESP will 
then not stabilize the vehicle.
Warning!
G
When the 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.

82 Safety and SecurityDriving safety systemsFour wheel electronic traction system (4MATIC) with the ESP
Models with all-wheel-drive only.
The 4MATIC improves vehicle’s ability to 
use available traction, e.g. during winter 
operation in mountains under snowy 
conditions, by applying power to all four 
wheels.Warning!
G
If you see the ESP warning lampv flash-
ing in the speedometer, 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.
!Do not tow with one axle raised.
Otherwise the transfer case can be 
damaged, which is not covered by the 
Mercedes-Benz Limited Warranty.!Performance testing must only be con-
ducted on a two-axle dynamometer.
Otherwise the transfer case can be 
damaged, which is not covered by the 
Mercedes-Benz Limited Warranty.
!Because of the ESP’s automatic 
operation, the engine must be shut off 
(SmartKey in starter switch position0 
or1) when the parking brake is being 
tested on a brake test dynamometer
Active braking action through ESP may 
otherwise seriously damage the front 
or rear axle brake system.
Operational tests with the engine 
running can only be conducted on a 
two-axle dynamometer.iAt highly demanding operating condi-
tions, the electronic traction system 
may temporarily switch off to prevent 
overheating of the drive wheel brakes.

96 Controls in detailLocking and unlockingAutomatic central locking
The doors and the trunk automatically lock 
when the ignition is switched on and the 
wheels are turning at vehicle speeds of 
approximately 9 mph (15 km/h) or more.
You can open a locked door from the 
inside. Open door only when conditions 
are safe to do so.
You can deactivate the automatic locking 
mode using the control system, see “Set-
ting automatic locking” (
page 145). 
Locking and unlocking from the inside
You can lock or unlock the doors and the 
trunk from inside using the central locking 
or unlocking switch. This can be useful, for 
example, if you want to lock the vehicle 
before starting to drive.
You cannot lock or unlock the fuel filler flap 
with the central locking or unlocking 
switch.
iThe doors unlock automatically after an 
accident if the force of the impact 
exceeds a preset threshold.
To prevent the vehicle door locks from 
locking, deactivate the automatic 
central locking when the vehicle
is pushed or towed
is on a test stand
Warning!
G
When leaving the vehicle, always remove the 
SmartKey from the starter switch, take it 
with you and lock the vehicle. Do not leave 
children unattended in the vehicle, or with 
access to an unlocked vehicle. Unsuper-
vised use of vehicle equipment may cause 
an accident and/or serious personal injury.

If the exterior lamp switch is set toU,
the headlamps may switch off unexpect-
edly when the system senses bright 
ambient light, for example light from 
oncoming traffic.
the headlamps will not be automatically 
switched on under foggy conditions. 
To minimize risk to you and to others, 
activate headlamps by turning exterior lamp 
switch toB when driving or when traffic 
and / or ambient lighting conditions require 
you to do so.
In low ambient lighting conditions, only 
switch from positionU toB with the 
vehicle at a standstill. Switching fromU 
toB will briefly switch off the 
headlamps. Doing so while driving in low 
ambient lighting conditions may result in an 
accident.
The automatic headlamp feature is only an 
aid to the driver. The driver is responsible for 
the operation of the vehicle's lights at all 
times.
