71 Safety and Security
Driving and safety systems
Driving and safety systems
In this section you will find information on
the following driving safety systems:

ABS (Antilock Brake System)


BAS (Brake Assist System)


4-ETS (Electronic Traction System)


EBP (Electronic Brake Proportioning)


ESP (Electronic Stability Program)
ABS
The 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 ap-
proximately 5 mph (8 km/h) independent
of road surface conditions.
On slippery road surfaces, the ABS will re-
spond even with light brake pressure.
The
-
warning lamp in the instrument
cluster (page 25) lights up when you
turn the key to position2. It goes out when
the engine is running.
iIn winter operation, the maximum ef-
fectiveness of the ABS, ESP, EBP and
4-ETS is only achieved with winter tires
(M + S tires), or snow chains as re-
quired.
Warning!
G
The following factors increase the risk of ac-
cidents:

Excessive speed, especially in turns


Wet and slippery road surfaces


Following another vehicle too closely
ABS, BAS, ESP and 4-ETS cannot reduce this
risk.
Always adjust your driving style to the pre-
vailing road and weather conditions.
Warning!
G
Do not pump the brake pedal. Use firm,
steady brake pedal pressure instead. Pump-
ing the brake pedal defeats the purpose of
ABS and significantly reduces braking effec-
tiveness.

76 Safety and SecurityDriving and safety systemsLOW RANGE – ESP
During off-road driving a special low range
system for the ESP is operational with
transmission in LOW RANGE mode
(page 118).
In the LOW RANGE mode ESP operates in
a traction improving fashion specifically
adapted for off-road driving. At speeds be-low 27 mph (45 km / h), the ESP assists in
over-/understeering, thus improving vehi-
cle traction.
Switching off the ESP
To improve the vehicle’s traction, turn off
the ESP in driving situations where it would
be advantageous to have drive wheels spin
and thus cut into surfaces for better grip
such as:


starting out on slippery surfaces and in
deep snow in conjunction with snow
chains


in sand or gravel


when driving off-roadWhen the ESP is turned off


engine torque is not limited.


the drive wheels can spin.
This helps the wheels cut into surfaces
for a better grip.
!The engine must be shut off when

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


the vehicle is being towed with the
front axle raised.
Otherwise, the ESP will engage the
brakes and seriously damage the brake
system.
The ESP will only function properly if
you use wheels of the recommended
tire size (
page 279).
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.
!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.iTurn ESP on immediately if the afore-
mentioned circumstances do not apply
anymore.

184 OperationDriving instructionsTire speed rating
Additional information on winter tires can
be found under “Winter tires”
(page 213).
ML 320, ML 350
Your vehicle is factory equipped with
“H”-rated tires, which have a speed rating
of 130 mph (210 km/h).
ML 500
Your vehicle is factory equipped with
“V”-rated tires, which have a speed rating
of 150 mph (240 km/h).
An electronic speed limiter prevents your
vehicle from exceeding the speed rating.
ML 55 AMG
Your vehicle is factory equipped with
“W”-rated tires, which have a speed rating
of 168 mph (270 km/h).
Despite of the tire speed rating, local
speed limits should be obeyed. Use pru-
dent driving speeds appropriate to prevail-
ing conditions.
Winter driving instructions
The most important rule for slippery or icy
roads is to drive sensibly and to avoid
abrupt acceleration, braking and steering
maneuvers. Do not use the cruise control
system under such conditions.
When the vehicle is in danger of skidding,
move selector lever to positionN. Try to
keep the vehicle under control by correc-
tive steering action.Road salts and chemicals can adversely af-
fect braking efficiency. Increased pedal
force may become necessary to produce
the normal brake effect.
We therefore recommend depressing the
brake pedal periodically when traveling at
length on salt-strewn roads.Warning!
G
Even when permitted by law, never operate
a vehicle at speeds greater than the maxi-
mum speed rating of the tires.
Exceeding the maximum speed for which
tires are rated can lead to sudden tire fail-
ure, causing loss of vehicle control and pos-
sibly resulting in an accident and/or serious
injury and possible death, for you and for
others.
iInformation on driving with snow
chains (
page 214).
Warning!
G
On slippery road surfaces, never downshift
in order to obtain braking action. This could
result in drive wheel slip and reduced vehi-
cle control. Your vehicle’s ABS will not pre-
vent this type of control loss.
Do not use LOW RANGE mode when driving
on ice or packed snow. At speeds below
18 mph (30 km / h) vehicle steering is ad-
versely affected by the LOW RANGE ABS
(page 72).

214 OperationWinter drivingBlock heater (Canada only)
The engine is equipped with a block heat-
er.
The electrical cable may be installed at
your authorized Mercedes-Benz Center.
Snow chains
Snow chains should only be driven on
snow-covered roads at speeds not to ex-
ceed 30 mph (50 km/h). Remove chains
as soon as possible when driving on roads
without snow. Observe the following guidelines when us-
ing snow chains:


Chains should only be used on all four
wheels. With only two chains available,
they should be mounted on the rear
wheels. Follow the manufacturer’s
mounting instructions.


Use only snow chains that are ap-
proved by Mercedes-Benz. Your autho-
rized Mercedes-Benz Light Truck
C e n t e r w i l l b e g l a d t o a d v i s e y o u o n t h i s
subject.
iWhen driving with snow chains, you
may wish to deactivate the ESP
(page 76) before setting the vehicle
in motion. This will improve the
vehicle’s traction.
!ML 55 AMG
Do not use snow chains with tire size
285/50 R 18.

279 Technical data
Rims and tires
Rims and tires
Use only tires and rims which have been
specifically developed for your vehicle and
tested and approved by Mercedes-Benz.
Other tires and rims can have detrimental
effects, such as

poor handling characteristics


increased noise


increased fuel consumption
Rims and tires
!Moreover, tires and rims not approved
by Mercedes-Benz may, under load, ex-
hibit dimensional variations and differ-
ent tire deformation characteristics
under load that could cause them to
come into contact with the vehicle
body or axle parts. Damage to the tires
or the vehicle may be the result.
iFurther information on tires and rims is
available at any authorized
Mercedes-Benz Light Truck Center. A
tire inflation pressure table is located
on the fuel filler cap of the vehicle. The
tire pressure should be checked regu-
larly and should only be adjusted on
cold tires. Follow tire manufacturer’s
maintenance recommendation includ-
ed with vehicle.
