0The key can be withdrawn in this position only. The 
steering is locked when the key is removed from the 
steering lock. If necessary, move steering wheel 
slightly to allow the locking mechanism to engage. 
The key can only be removed with the selector lever 
in position “P”. After removing the key or with the 
key in steering lock position 0, the selector lever is 
locked in position “P”.1Steering is unlocked.
(If necessary, move steering wheel slightly to allow 
the key to be turned clockwise to position 1.) Most 
electrical consumers can be operated. For detailed

cluster displayPractical hints Car care Index Maneuvering
To maneuver in tight areas, e.g. when pulling into a 
parking space, control the vehicle speed by gradually 
releasing the brakes. Accelerate gently and never 
abruptly step on the accelerator.
To rock a vehicle out of soft ground (mud or snow), 
alternately shift from forward to reverse, while applying 
slight partial throttle.
Rocking a vehicle free in this manner may cause the 
ABS or traction system malfunction indicator lamp to 
come on. Turn off and restart the engine to clear the 
malfunction indication.Towing a trailer
If the transmission hunts between gears on inclines, 
manually shift to a lower gear (select “4”, “3”, “2” 
or “1”). A lower gear and reduction of speed reduces the 
chance of engine overloading and / or overheating.
At very steep inclines, not manageable with selector 
lever in position “1”, switch transfer case to LOW 
RANGE, see page 209 for instructions on how to engage 
LOW RANGE.
For instructions on trailer towing refer to page 190.
Wa r n i n g !
Getting out of your vehicle with the selector lever 
not fully engaged in position “P” is dangerous. 
Also, when parked on an incline, position “P” alone 
may not prevent your vehicle from moving, 
possibly hitting people or objects.Always set the parking brake in addition to shifting 
to position “P”, see page 173 for parking brake. When parked on an incline, also turn front wheel 
against curb.
Wa r n i n g !
When leaving the vehicle always remove the key 
from the steering lock, and lock the vehicle. Do not 
leave children unattended in the vehicle, or with 
access to an unlocked vehicle. Children could move 
the gear selector lever from position “P”, which 
could result in an accident or serious injury.

leave children unattended in the vehicle, or with 
access to an unlocked vehicle. Children could 
release the parking brake, which could result in an 
accident or serious injury.

219 Malfunction and indicator lamps
Te ch n ica l
data Instruments 
and controlsOperation DrivingInstrument 
cluster displayPractical hints Car care Index Brake warning lamp
When the brake warning lamp appears 
while the engine is running, this means:
•there is insufficient brake fluid in the reservoir 
(engine running and parking brake released), or
•the parking brake is set (engine running)
•the electronic brake proportioning (EBP) system is 
malfunctioning.
Note:
If you find that the minimum mark on the brake fluid 
reservoir is reached, have the brake system checked for 
brake pad thickness and leaks.Supplemental restraint system (SRS) indicator lamp
The operational readiness of the airbag 
system is verified by the indicator lamp 
“SRS” in the instrument cluster when 
turning the key in steering lock to position 1 or 2. If no 
fault is detected, the lamp will go out after 
approximately 5 seconds; after the lamp goes out, the 
system continues to monitor the components and 
circuitry of the airbag system and will indicate a 
malfunction by coming on again.
See page 56 for notes on airbags, page 55 for belt 
tensioners, and page 65 for infant and child seat 
restraints.
Wa r n i n g !
Driving with the brake warning lamp illuminated 
can result in an accident. Have your brake system 
checked immediately if the brake warning lamp 
stays on. Don’t add brake fluid before checking the 
brake system. Overfilling the brake fluid reservoir 
can result in spilling brake fluid on hot engine 
parts and the brake fluid catching fire. You can be 
seriously burned.BRAKE
Wa r n i n g !
In the event a malfunction of the “SRS” is indicated 
as outlined above, the “SRS” may not be 
operational. For your safety, we strongly 
recommend that you visit an authorized 
Mercedes-Benz Light Truck Center immediately to 
have the system checked; otherwise the “SRS” may 
not be activated when needed in an accident, which 
could result in serious or fatal injury, or it might 
deploy unexpectedly and unnecessarily which 
could also result in injury.SRS
