accident, the glass may shatter. This may re-
sult in an opening in the roof.
In a vehicle rollover, occupants not wearing
their seat belts or not wearing them properly
may be thrown out of the opening.
Such an opening also presents a potential
for injury for occupants wearing their seat
belts properly as entire body parts or por-
tions of them may protrude from the pas-
senger compartment.
When leaving the vehicle, always remove the
SmartKey or SmartKey with KEYLESS-GO*
from the starter switch, take it with you, and
lock the vehicle. Do not leave children
unattended in the vehicle, or with access to
an unlocked vehicle. Unsupervised use of
vehicle equipment can cause an accident
and/or serious personal injury.!
To avoid damaging the seals, do not trans-
port any objects with sharp edges which can
stick out of the tilt/sliding panel.
Do not open the tilt/sliding panel if there is snow
or ice on the roof, as this could result in malfunc-
tions.

Roof rack*
Flip the covers upward.
Only attach the roof-rack system to the
anchorage points under the covers.
Observe manufacturer’s instructions
for installation.
Loading instructions
The total load weight including vehicle oc-
cupants and luggage/cargo should not ex-
ceed the load limit or vehicle capacity
weight as indicated on the corresponding
placard located on the driver’s door B-pillar
(page 503).
Warning!
G
Only use roof racks approved by
Mercedes-Benz for your vehicle model to
avoid damage to the vehicle.
Follow the manufacturer’s installation
instructions. Otherwise, an improperly
attached roof rack system or its load could
become detached from the vehicle.
Do not exceed the maximum roof load of
220 lb (100 kg).
Take into consideration that when the roof
rack is loaded, the handling characteristics
are different from those when operating the
vehicles without the roof rack loaded.
!
Load the roof rack in such a way that the ve-
hicle cannot be damaged while driving.
Make sure

G
Always fasten items being carried as secure-
ly as possible using cargo tie-down hooks
and fastening materials appropriate for the
weight and size of the load.
In an accident, during hard braking or sud-
den maneuvers, loose items will be thrown
around inside the vehicle and can cause in-
jury to vehicle occupants unless the items
are securely fastened in the vehicle.
To help avoid personal injury during a colli-
sion or sudden maneuver, exercise care
when transporting cargo. Put luggage or car-
go in the trunk if possible.

Driving instructions
Driving instructions
Drive sensibly – save fuel
Fuel consumption, to a great extent,
depends on driving habits and operating
conditions.
To save fuel you should:
Keep tires at the recommended tire
inflation pressures.
Remove unnecessary loads.
Remove roof rack when not in use.
Allow engine to warm up under low
load use.
Avoid frequent acceleration and decel-
eration.
Have all maintenance work performed
at the intervals specified in the Mainte-
nance Booklet and as required by the
Maintenance System (U.S. vehicles) or
FSS PLUS (Canada vehicles). Contact
an authorized Mercedes-Benz Center.
Fuel consumption is also increased by driv-
ing in cold weather, in stop-and-go traffic,
on short trips, and in hilly area.

the footwell, make sure that the pedals still
have sufficient clearance.Warning!

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 ve-
hicle.
