cluster displayPractical hints Car care Index Road salts and chemicals can adversely affect 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. This can
bring road salt impaired braking efficiency back to
normal. A prerequisite is, however, that this be done
without endangering other drivers on the road.
If the vehicle is parked after being driven on salt treated
roads, the braking ef ficiency should be tested as soon as
possible after driving is resumed while observing the
safety rules in the previous paragraph.Winter driving
Have your vehicle winterized at your authorized
Mercedes-Benz Light Truck Center before the onset of
winter.
•Check the engine oil. 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, see page 361.
•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 form ulated for b elow f r eezin g temperatures
see page 307.
•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.
Wa r n i n g !
If the vehicle becomes stuck in snow, make sure
that snow is kept clear of the exhaust pipe and
from around the vehicle with engine running.
Otherwise, deadly carbon monoxide (CO) gases may
enter vehicle interior resulting in unconsciousness
and death.To assure sufficient fresh air ventilation, open a
window slightly on the side of the vehicle not
facing the wind.

cause the “CHECK ENGINE” lamp to illuminate.
Fuel tank capacity approximately 25.4 US gal (96.0 l).
This includes approximately 5.3 US gal (20.0 l) reserve.
Use premium unleaded gasoline: Posted Octane
Index 91 (Average of 96 RON / 86 MON).
•Engine oil
Engine oil level check, see page 127 and page 304.
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 306 and 365.
• Spark plugs
Approved spark plugs, see page 360.
•Tire pressure
For tire pressure, refer to tire pressure label inside
the fuel filler flap. See page 318 for further details.
•Air conditioner
R-134a refrigerant and special PAG lubricant, see
page 363.
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.
