have switched off due to a mal-
function. The BAS is also 
switched off.
The brake system is still func-
tional but without the EBP, the 
ABS, and the ESP

Continue driving with added caution. 
Wheels may lock during hard braking, 
reducing steering capability.
Have the system checked at an 
authorized Mercedes-Benz Light Truck 
Center as soon as possible.
Failure to follow these instructions increases 
the risk of an accident.

Tire pressure
Check tires
The pressure is too low in one or 
more tires.
Check and correct tire inflation pressure as 
required.
Tire pressure
Caution - tire defect
One or more tires are deflating.
Carefully bring the vehicle to a halt, avoiding 
abrupt steering and braking maneuvers.
If necessary, change the wheel.
Caution - tire defect
Vehicles with Advanced TPMS*:
One or more tires are deflating.
The respective tire is shown in the 
multifunction display.
Carefully bring the vehicle to a halt, avoiding 
abrupt steering and braking maneuvers.
If necessary, change the wheel.
Warning!
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 will cause excessive 
heat build-up and possibly a fire.

Preparing the vehicle
Park the vehicle in a safe distance from 
moving traffic on a hard, flat surface 
when possible.
Turn on the hazard warning flasher 
(page 142).
Turn the steering wheel so that the 
front wheels are in a straight-ahead 
position.
Set the parking brake (
page 57).
Set the automatic transmission to park 
positionP (
page 187).
Turn off the engine (
page 39).
Remove the SmartKey from the starter 
switch.
Vehicles with KEYLESS-GO*:
Turn off the engine by pressing the 
KEYLESS-GO* button once 
(page 67).
Open the driver’s door (this puts 
the starter switch in position0, 
same as with the SmartKey re-
moved from the starter switch). The 
driver’s door then can be closed 
again.
Have any passenger exit the vehicle at 
a safe distance from the roadway.
Warning!
G
The dimensions of the spare wheel 
(Minispare wheel or collapsible tire) are dif-
ferent from those of the road wheels. As a 
result, the vehicle handling characteristics 
change when driving with a spare wheel 
mounted. Adapt your driving style accord-
ingly.
The spare wheel is for temporary use only. 
When driving with a spare wheel mounted, 
ensure proper tire pressure and do not ex-
ceed a vehicle speed of 50 mph (80 km/h).
Drive to the nearest Mercedes-Benz Light 
Truck Center as soon as possible to have the 
spare wheel replaced with a regular road 
wheel.
Never operate the vehicle with more than 
one spare wheel mounted.
Do not switch off the ESP
® when a 
Minispare wheel is mounted.
Warning!
G
Vehicles with air suspension package*:
Do not open or close any doors or the 
tailgate while mounting a spare wheel. The 
vehicle could rise or lower to a previously 
selected level. You or others could be 
injured as a result.
i
Open door only when conditions are safe to 
do so.

Towing the vehicle
Warning!
G
If circumstances require towing the vehicle 
with all wheels on the ground, always tow 
with a tow bar if:
the engine will not run
there is a malfunction in the power 
supply or in the vehicle’s electrical sys-
tem
Prior to towing the vehicle with all wheels on 
the ground, make sure the starter switch is 
in position2 (
page 40).
Warning!
G
With the engine not running, there is no 
power assistance for the brake and steering 
systems. In this case, it is important to keep 
in mind that a considerably higher degree of 
effort is necessary to brake and steer the 
vehicle. Adapt your driving accordingly.
i
To signal turns while being towed with 
hazard warning flasher in use, set the starter 
switch to position2 and activate combination 
switch for left or right turn signal in usual manner 
– only the selected turn signal will operate.
Upon canceling the turn signal, the hazard 
warning flasher will operate again.
i
If the battery is disconnected or discharged, 
the automatic transmission will remain locked in 
positionP and the SmartKey will not turn in the 
starter switch. For more information, see “Bat-
tery” (page 507) and “Jump starting” 
(
page 515).
!
When towing the vehicle with all wheels on 
the ground, note the following:
With the automatic central locking activated and 
the ignition in position2 (
page 40), the vehicle 
doors lock if the left front wheel is turning at a 
speed of approximately 9 mph (15 km/h) or 
above.
To prevent the vehicle doors from locking, 
deactivate the automatic central locking 
(
page 126).
Towing of the vehicle should only be done using 
the towing eye bolt. Never attach tow cable, tow 
rope or tow rod to vehicle chassis, frame or sus-
pension parts.
