4-ETS
The 4-Electronic Traction System (4-ETS)
improves vehicle’s ability to utilize avail-
able traction, especially under slippery
road conditions. The brakes are applied to
the spinning wheel and power is allowed to
flow to the wheel(s) with traction.
The 4-ETS function is available between
vehicle speeds of 0 mph (km/h) and
37 mph (60 km/h).
The ESP
® warning lampv in the instru-
ment cluster (
page 26) comes on when
you switch on ignition (
page 39). It goes
out when the engine is running.
The ESP
® warning lampv starts to
flash at any vehicle speed, as soon as a tire
loses traction and the wheel begins to
spin.
Warning!G
The 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, includ-
ing those resulting from excessive speed in
turns, following another vehicle too closely,
or hydroplaning. 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 danger-
ous manner which could jeopardize the
user’s safety or the safety of others.
Warning!G
When you see the ESP® warning lampv
flashing in the instrument cluster, then
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 4-ETS cannot prevent accidents result-
ing from excessive speed.

Warning!G
Never switch off the ESP® when you see the
ESP® warning lampv 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 result-
ing 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, fol-
lowing another vehicle too closely, or hydro-
planing. Only a safe, attentive, and skillful
driver can prevent accidents. The capabili-
ties of a ESP
® equipped vehicle must never
be exploited in a reckless or dangerous
manner which could jeopardize the user’s
safety or the safety of others.
!Operational or performance test must only
be conducted on a two-axle dynamometer. If
such tests are necessary, contact an authorized
Mercedes-Benz Light Truck Center. You could
otherwise seriously damage the brake system or
the transfer case which is not covered by the
Mercedes-Benz Limited Warranty.
!Because the ESP® operates automatically,
the engine and ignition must be shut off when
testing the parking brake on a brake test
dynamometer and such testing should be no
longer than 10 seconds.
Active braking action through ESP
® may
otherwise seriously damage the brake system
which is not covered by the Mercedes-Benz
Limited Warranty.
iThe ESP® will only function properly if you
use wheels of the recommended tire size
(
page 416).
iThe ABS, BAS, and ESP® are automatically
switched off when the differential locks are
switched on (
page 175).

Switching off the ESP®
To improve the vehicle’s traction, switch
off the ESP® in driving situations where it
would be advantageous to have the drive
wheels spin and thus cut into surfaces for
better grip such as:

when driving with snow chains

in deep snow

sand or gravel

when driving off-roadWhen 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 4-ETS will still apply the brake to a
spinning wheel

the ESP® continues to operate when
you are braking

you cannot activate the cruise control
system

the cruise control system switches off
if currently activatedThe ESP
® switch is located on the upper
part of the center console.
1ESP
® switch
With the engine running, press
switch1.
The ESP
® warning lampv in the
instrument cluster comes on.
The ESP
® is deactivated.
Warning!G
The ESP® should not be switched off during
normal driving other than in the circum-
stances described below. Disabling of the
system will reduce vehicle stability in stan-
dard driving maneuvers.
Warning!G
Switch on the ESP® immediately if the afore-
mentioned circumstances do not apply any-
more. Otherwise the ESP
® will not stabilize
the vehicle when it is starting to skid or a
wheel is spinning.
iWhen the ESP® is switched off and one or
more drive wheels are spinning, the ESP® warn-
ing lampv in the instrument cluster flashes.
However, the ESP
® will then not stabilize the
vehicle.

95 Safety and Security
Driving safety systems
Even if the ESP® has been switched off, it
is still active in the following situations:

when braking

at vehicle speeds up to approximately
37 mph (60 km/h), if one wheel
reaches the grip limit, e.g. when the
street is icy on one side
The brake is applied until the wheel
regains sufficient traction.
If one or more drive wheels are spinning,
the ESP
® warning lampv in the instru-
ment cluster flashes, regardless of the
speed.Switching on the ESP
®
Press switch1 once more.
The ESP
® warning lampv in the
instrument cluster goes out.
You are now again in normal driving
mode with the ESP
® switched on.
For more information, see “Practical hints”
(
page 330).
Warning!G
When the ESP® warning lampv is
illuminated continuously, the ESP® is
switched off or it is not operational due to a
malfunction.
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 of time with the ESP® switched
off. This may cause serious damage to the
drivetrain which is not covered by the
Mercedes-Benz Limited Warranty.
iIf the ESP® is switched off, it will be auto-
matically activated when exceeding a vehicle
speed of 37 mph (60 km/h) or exceeding a
severity threshold of side acceleration.

as possible.
iThe instrument cluster illumination is
dimmed or brightened automatically to suit
ambient light conditions.
The instrument cluster illumination will also be
adjusted automatically when you switch on the
vehicle’s exterior lamps.

Warning!G

Driving when your engine is overheated
can cause some fluids which may have
leaked into the engine compartment to
catch fire. You could be seriously
burned.

Steam from an overheated engine can
cause serious burns which can occur
just by opening the hood. Stay away
f r o m t h e e n g i n e i f y o u s e e o r h e a r s t e a m
coming from it.
Stop the vehicle in a safe location away from
other traffic. Turn off the engine, get out of
the vehicle and do not stand near the vehicle
until the engine has cooled down.
!Excessive coolant temperature triggers a
warning message in the multifunction display
(
page 348).
The engine should not be operated with the
coolant temperature above 248°F (120°C).
Doing so may cause serious engine damage
which is not covered by the Mercedes-Benz
Limited Warranty.
iDuring severe operating conditions, e.g.
stop-and-go traffic, the coolant temperature may
rise close to 248°F (120°C).
