Index
some jurisdictions, it is forbidden for drivers
to use mobile phones while driving.
Only
operate
COMAND (Cockpit Management
and Data System) in compliance with all legal
requirements and when the road, weather and
traffic conditions permit. You may otherwise
not be able to observe the traffic conditions,
endangering yourself and others.
Remember that your vehicle covers a distance
of 44 ft (approximately 14 m) a second when
it is traveling at only 30 mph (approximately
50 km/h).
Drive sensibly – save fuel Observe the following tips to save fuel:
R
The tires should always be inflated to the
recommended tire pressure.
R Remove unnecessary loads.
R Warm up
the engine at low engine speeds.
R Avoid frequent acceleration or braking.
R Observe the service intervals in the
Maintenance Booklet or in the service
interval display. Have all the maintenance
work carried in accordance with Daimler
AG regulations.
Fuel consumption also increases when
driving in cold weather, in stop-and-go traffic
and in mountainous terrain.
Drinking and driving G
WARNING
Drinking
and driving and/or taking drugs and
driving are very dangerous combinations.
Even a small amount of alcohol or drugs can
affect your reflexes, perceptions and
judgment.
The possibility of a serious or even fatal
accident are
greatly increased when you drink
or take drugs and drive.
Do not drink or take drugs and drive or allow
anyone to drive who has been drinking or
taking drugs. Pedals G
WARNING
Make sure absolutely no objects are
obstructing the pedals' range of movement.
Keep the driver's footwell clear of all
obstacles. If there are any floormats or
carpets in the footwell, make sure that the
pedals still have sufficient clearance.
During sudden driving or braking maneuvers,
the objects could get caught between the
pedals. You could then no longer brake or
accelerate. This could lead to accidents and
injury.
Rolling with the engine switched off G
WARNING
There
is no power assistance for the steering
and the
brake when the engine is not running.
Steering and braking requires significantly
more effort and you could lose control of the
vehicle and cause an accident as a result.
Do not turn off the engine while the vehicle is
in motion. G
WARNING
Electric power is required to operate the
brake system.
A malfunction in the power supply or in the
vehicle's electrical system can impair the
operation of the brake system and result in
the brake system switching to emergency
mode. In this situation, the red brake system
warning lamp and warning messages may
appear in the instrument cluster while the
vehicle is moving. When braking, the driver
must depress the brake pedal considerably
more firmly and much further in order to
obtain the expected braking effect. If
necessary, apply full pressure to the brake
pedal. Brakes are only applied to the front
wheels. Stopping distance is increased. Driving tips

Tire Pressure The tire pressure loss warning system has detected a significant
loss in pressure.

G WARNING
With tire pressures which are too low, there is a risk of the
following hazards:
R they may burst, especially as the load and vehicle speed
increase.
R they may
wear excessively and/or unevenly, which may greatly
impair tire traction.
R the driving characteristics, as well as steering and braking, may
be greatly impaired.
There is a risk of an accident.
