Driving instructions
Drive sensibly – save fuel
Fuel consumption, to a great extent, depends on driving 
habits and operating conditions.
To save fuel you should:
•keep tires at the recommended inflation pressures,
•remove unnecessary loads,
•remove roof rack when not in use,
•allow engine to warm up under low load use,
•avoid frequent acceleration and deceleration,
•have all maintenance work performed at regular 
intervals by an authorized Mercedes-Benz Light 
Truck Center.
Fuel consumption is also increased by driving in cold 
weather, in stop-and-go traffic, on short trips and in hilly 
country.Drinking and driving
Pedals
Wa r n i n g !
Drinking or taking drugs and driving can be a very 
dangerous combination. Even a small amount of 
alcohol or drugs can affect your reflexes, 
perceptions and judgement.The possibility of a serious or even fatal accident is 
sharply increased when you drink or take drugs 
and drive.Please don’t drink or take drugs and drive or allow 
anyone to drive after drinking or taking drugs.Wa r n i n g !
Keep driver’s foot area clear at all times. Objects 
stored in this area may impair pedal movement.

Specified tire pressures must be maintained. This 
applies particularly if the tires are subjected to high 
loads (e.g. high speeds, heavy loads, high ambient 
temperatures).
Aquaplaning
Depending on the depth of the water layer on the road, 
aquaplaning may occur, even at low speeds and with 
new tires. Reduce vehicle speed, avoid track grooves in 
the road and apply brakes cautiously in the rain.Tire traction
The safe speed on a wet, snow covered or icy road is 
always lower than on a dry road.
You should pay particular attention to the condition of 
the road whenever the outside temperatures are close to 
the freezing point.
We recommend M+S rated radial-ply tires with a 
minimum tread depth of approximately 1/8 in (4 mm) 
for the winter season for all four wheels to insure 
normal balanced handling characteristics. On packed 
snow, they can reduce your stopping distance as 
compared with summer tires. Stopping distance, 
however, is still considerably greater than when the 
road is not snow or ice covered.
Wa r n i n g !
Do not drive with a flat tire. A flat tire affects the 
ability to steer or brake the vehicle. You may lose 
control of the vehicle. Continued driving with a flat 
tire or driving at high speed with a flat tire will 
cause excessive heat build-up and possibly a fire.
Wa r n i n g !
If ice has formed on the road, tire traction will be 
substantially reduced. Under such weather 
conditions, drive, steer and brake with extreme 
caution.

Checklist before off-road driving
•Tires: Check the tread depth and maintain specified 
tire pressure (see tire pressure label inside the fuel 
filler flap). Check tires for possible damage and 
remove foreign objects. The valve caps must be 
mounted.
•Rims: Dented or bent rims can cause tire pressure 
loss and damage the tire beads. For this reason 
change rims before driving off-road.
• Vehicle tool kit: Check if the vehicle jack is 
functional. In all cases take the vehicle tool kit, a 
strong tow rope, a shovel and a small plank (to put 
under the vehicle jack on sandy soil) with you.Driving in steep terrain
Slope angle:
126° (ML 320 and ML 430)
23° (ML 55 AMG)
226° (ML 320 and ML 430)
21° (ML 55 AMG)
Switch to LOW RANGE mode before starting to drive up 
or down steep inclines, see page 209.
Maximum vehicle climbing ability is a 60% grade.

199 Driving systems
Te ch n ica l
data Instruments 
and controlsOperationDrivingInstrument 
cluster displayPractical hints Car care Index 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.
The malfunction indicator lamp for the electronic 
stability program (ESP) is combined with the BAS 
malfunction indicator lamp.
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.

Te ch n ica l
data Instruments 
and controlsOperationDrivingInstrument 
cluster displayPractical hints Car care Index Leaving the engine running and the fuel cap open can 
cause the “CHECK ENGINE” lamp to illuminate.
Fuel tank capacity approximately 19.0 US gal (72.0 l).
This includes approximately 3.2 US gal (12.0 l) reserve.
Use premium unleaded gasoline: Posted Octane 
Index 91 (Average of 96 RON / 86 MON).
•Engine oil
Engine oil level check, see page 89 and page 233.
Fill quantity between upper and lower dipstick 
marking level: 2.1 US qt (2.0 l).
Recommended engine oils, see Approved Service 
Products sheet.• Coolant
For normal replenishing, use water (potable water 
quality).
For further information (e.g. anticorrosion/
antifreeze), see page 292.
• Spark plugs
Approved spark plugs, see page 290.
• Tire pressure
For tire pressure, refer to tire pressure label inside 
the fuel filler flap. See page 250 for further details.
• Air conditioner
R-134a refrigerant and special PAG lubricant, see 
page 294.
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.

cluster displayPractical hintsCar care Index Rotating wheels
The wheels can be rotated according to the degree of 
tire wear while retaining the same direction of travel.
Rotating, however, should be carried out as 
recommended by the tire manufacturer, before the 
characteristic tire wear pattern (shoulder wear on front 
wheels and tread center wear on rear wheels) becomes 
visible, as otherwise the driving properties deteriorate.
Important!
Unidirectional tires must always be mounted with arrow 
on tire sidewall pointing in direction of vehicle forward 
movement.Notes:
Thoroughly clean the inner side of the wheels any time 
you rotate the wheels or wash the vehicle underside.
The use of retread tires is not recommended. Retread 
tires may adversely affect the handling characteristics 
and safety of the vehicle.
Dented or bent rims can cause tire pressure loss and 
dam age to t he tire bead s. For this reason, ch eck rims for 
damage at regular intervals. The rim flanges must be 
checked for wear before a tire is mounted. Remove 
burrs, if any.
Check and ensure proper tire inflation pressure after 
rotating the wheels. For tire inflation pressure see 
page 250.
