trailer tongue load). It is indicated on 
Certification label located on the driver's 
door B-pillar.
Kilopascal (kPa)

6.9 kPa to one psi; another metric unit for 
air pressure is bars. There are 
100 kilopascals (kPa) to one bar.
Maximum load rating
The maximum load in kilograms and 
pounds that can be carried by the tire.
Maximum loaded vehicle weight
The sum of curb weight, accessory weight, 
vehicle capacity weight and production 
options weight.Maximum tire inflation pressure
This number is the greatest amount of air 
pressure that should ever be put in the tire 
under normal driving conditions.
Normal occupant weight
The number of occupants the vehicle is 
designed to seat, multiplied by 
68 kilograms (150 lbs).
Occupant distribution
The distribution of occupants in a vehicle 
at their designated seating positions.
Production options weight
The combined weight of those installed 
regular production options weighing over 
5 lbs (2.3 kilograms) in excess of those 
standard items which they replace, not 
previously considered in curb weight or 
accessory weight, including heavy duty 
brakes, ride levelers, roof rack, heavy duty 
battery, and special trim.PSI (P
ounds per s
quare i
nch)
A standard unit of measure for air pressure 
-> bar, kilopascal (kPa).
Recommended tire inflation pressure
Recommended tire inflation pressure 
listed on placard located on driver's door 
B-pillar for normal driving conditions. 
Provides best handling, tread life and 
riding comfort.
Rim

342 Practical hintsWhat to do if …?Problem
Possible cause
Suggested solution
l
Only vehicles with Distronic*: 
The red distance warning lamp 
comes on while driving.
You are too close to the vehicle in front of 
you to maintain selected speed.
Apply the brakes immediately to in-
crease the following distance.
l
Only vehicles with Distronic*: 
The red distance warning lamp 
comes on while driving and you 
hear a warning sound.
You are gaining too rapidly on the vehi-
cle ahead of you.
The distance warning system has recog-
nized a stationary obstacle on your 
probable line of travel.
Apply the brakes immediately.
Carefully observe the traffic situation. 
You may need to brake or maneuver to 
avoid hitting an obstacle.
v
The yellow ESP warning lamp 
flashes while driving.
The ESP or traction control has come into 
operation because of detected traction loss 
in at least one tire.
Distronic* is deactivated.
When driving off, apply as little throttle 
as possible.
While driving, ease up on the accelera-
tor.
Adapt your speed and driving to the pre-
vailing road and weather conditions.
Do not deactivate the ESP.  Exceptions: 
(page 83).
Failure to follow these instructions increas-
es the risk of an accident.

408 Practical hintsTowing the vehicleMercedes-Benz recommends that the vehi-
cle be transported with all wheels off the 
ground using flatbed or appropriate wheel 
lift/dolly equipment. This method is pref-
erable to other types of towing.When circumstances do not permit the 
recommended towing methods, the vehi-
cle may be towed with all wheels on the 
ground or front wheels raised (except vehi-
cles with 4MATIC) only so far as necessary 
to have the vehicle moved to a safe loca-
tion where the recommended towing 
methods can be employed.
!Use flatbed or wheel lift/dolly equip-
ment with SmartKey in starter switch 
turned to position0.
Do not tow with sling-type equipment. 
Towing with sling-type equipment over 
bumpy roads will damage radiator and 
supports.
To prevent damage during transport, 
do not tie down vehicle by its chassis or 
suspension parts.
Switch off the tow-away alarm 
(page 89) and the automatic central 
locking (
page 112).
Do not tow-start the vehicle.
!Vehicles with 4MATIC:
Do not tow with one axle raised. Doing 
so could damage the transfer case, 
which is not covered by the 
Mercedes-Benz Limited Warranty.
All wheels must be on or off the ground. 
Observe instructions for towing the ve-
hicle with all wheels on the ground.
!If the vehicle is towed with the front 
axle raised (not permissible for vehicles 
with 4MATIC), the engine must be shut 
off (SmartKey in starter switch 
position0 or 1). Otherwise the ESP will 
immediately be engaged and will apply 
the rear wheel brakes.
When towing the vehicle with all wheels 
on the ground, the selector lever must 
be in positionN and the SmartKey 
must be in starter switch position2.
When towing the vehicle with all wheels 
on the ground or the front axle raised, 
the vehicle may be towed only for dis-
tances up to 30 miles (50 km) and at a 
speed not to exceed 30 mph 
(50 km/h).
