Electrical outlet 
Two electrical outlets can be found, one at the front  
passenger footwell, and the other in the rear 
compartment (always operational).  To  o p e n : 
Flip up cover and insert electrical plug (cigar lighter  
type). 
Note: 
The electrical outlets can be used to accommodate  
accessories (e.g. air pump, auxiliary lamps) up to 
maximum 180 W. 
Stowing things in the vehicle
Wa r n i n g ! 
To help avoid personal injury during a collision or  
sudden maneuver, always use partition net when  
transporting cargo. Always fasten items being  
carried as securely as possible using cargo tie-
down rings and fastening materials appropriate for  
the weight and size of the load.

Hood 
To  o pen : 
To unlock the hood, pull release lever (1) under the  
driver’s side of the instrument panel. At the same time a  
handle (2) will extend out of the radiator grill (it may be 
necessary to lift the hood up slightly). 
Caution! 
To avoid damage to the windshield wipers or hood, open  
the hood only with wipers in the parked position.  Pull handle (2) to its stop out of radiator grill and open  
hood (do not pull up on handle). 
To  c l o s e : 
Lower hood and let it drop into lock from a height of  
approximately 1 ft. (30 cm). 
To avoid hood damage, please make sure that hood is  
fully closed. If not, repeat closing procedure. Do not  
push down on hood to attempt to fully close it.

Wa r n i n g ! 
To help prevent personal injury, stay clear of  
moving parts when the hood is open and the engine 
is running. Be sure the hood is properly closed  
before driving. When closing hood, use extreme  
caution not to catch hands or fingers.The radiator fan may continue to run for  
approximately 30 seconds or even restart after the  
engine has been turned off. Stay clear from fan 
blades.
The engine is equipped with a transistorized  
ignition system. Because of the high voltage it is  
dangerous to touch any components (ignition coils, 
spark plug sockets, diagnostic socket) of the  
ignition system 
• with the engine running, 
• while starting the engine, 
• if ignition is “on” and the engine is turned   manually.If you see flames, steam or smoke coming from the  
engine compartment, or if the coolant temperature  
gauge indicates that the engine is overheated, do  
not open the hood. Move away from vehicle and do 
not open the hood until the engine has cooled. If  
necessary, call a fire department.

Checking engine oil level 
1  Oil dipstick 
2  Oil filler cap 
To check the engine oil level, park vehicle on level  
ground, with engine at normal operational temperature. 
Check engine oil level approximately 5 minutes after  
stopping the engine, allowing for the oil to return to the  
oil pan.  Wipe oil dipstick clean prior to checking the engine oil  
level. Fully insert dipstick in tube, and remove after 
three seconds to obtain accurate reading. 
Oil level must be between the  
lower (min) and upper (max) mark of 
the dipstick. 
Fill quantity between upper and lower dipstick marking,  
the level is approximately 2.1 US qt (2.0 l). 
Do not overfill the engine.
 Excessive oil must be drained  
or siphoned. It could cause damage to engine and 
catalytic converter not covered by the Mercedes-Benz  
Limited Warranty. 
See page 224 for low engine oil level warning. 
Note: 
See page 89 for engine oil level indicator.

Automatic transmission fluid level 
The transmission has a permanent fill of automatic  
transmission fluid. 
Regular automatic transmission fluid level checks and  
changes are not required. For this reason the dipstick is 
omitted. 
If you notice fluid leaks or gear shifting malfunctions,  
have your authorized Mercedes-Benz Light Truck Center  
check the transmission fluid level. 
Engine oil consumption 
Engine oil consumption checks should only be made  
after the break-in period. During the break-in period,  
higher oil consumption may be noticed and is normal.  
Frequent driving at high engine speeds results in 
increased consumption.  Coolant level 
To check the coolant level, the vehicle must be parked  
on level ground and the engine stopped. 
Check coolant level only when coolant is cold. 
The coolant level should reach the COLD LEVEL mark in  
the reservoir.P20.30-0241-20

Adding coolant 
If coolant has to be added, a 50 / 50 mixture of water and  
MB anticorrosion / antifreeze should be added. 
After adding coolant, close cap until you hear it click a  
few times. 
The drain plugs for the cooling system are located on  
the left and right side of the engine block directly above 
the engine mounts and at the bottom of the radiator. 
Anticorrosion / antifreeze mixture, see page 297.
Wa r n i n g ! 
In order to avoid possible serious burns or injury:  • Use extreme caution when opening the hood if   there are any signs of steam or coolant leaking 
from the cooling system, or if the coolant 
temperature gauge indicates that the coolant is 
overheated.
• Do not remove pressure cap on coolant   reservoir if engine temperature is above 194  °F  
(90  °C). Allow engine to cool down before  
removing cap. The coolant reservoir contains 
hot fluid and is under pressure.• Using a rag, slowly open cap approximately  1/2 turn to relieve excess pressure. If opened  
immediately, scalding hot fluid and steam will  
be blown out under pressure.• Do not spill antifreeze on hot engine parts.  Antifreeze contains ethylene glycol which may 
burn if it comes into contact with hot engine  
parts.

Windshield washer/headlamp cleaning system 
The reservoir should be refilled with MB Windshield  
washer concentrate and water (or commercially 
available premixed windshield washer solvent/ 
antifreeze, depending on ambient temperatures). 
1 Windshield washer / headlamp cleaning / rear  
window wiper / washer system fluid reservoir 
Vehicles without headlamp cleaning system: 
Capacity approximately 5.3 US qt (5.0 l). 
Vehicles with headlamp cleaning system: 
Capacity approximately 8.0 US qt (7.6 l).
Wa r n i n g ! 
Washer solvent / antifreeze is highly flammable. Do  
not spill washer solvent / antifreeze on hot engine  
parts, because it may burn. You can be seriously  
burned.

Wa r n i n g ! 
The jack is designed exclusively for jacking up the  
vehicle at the jack take-up brackets built into either 
side of the vehicle. To help avoid personal injury,  
use the jack only to lift the vehicle during a wheel  
change. Never get beneath the vehicle while it is 
supported by the jack. Keep hands and feet away  
from the area under the lifted vehicle. Always  
firmly set parking brake and block wheels before 
raising vehicle with jack.Do not disengage parking brake while the vehicle is 
raised. Be certain that the jack is always vertical 
when in use, especially on hills. Always try to use  
the jack on level surface. Be sure that the jack arm  
end is fully seated in the jack take-up bracket. 
Always lower the vehicle onto sufficient capacity  
jackstands before working under the vehicle.
