General driving tips
Important safety notes G
WARNING
Always remember that you must concentrate primarily on driving the vehicle. The driver's concentration must always be directed pri-
marily at road traffic. For your own safety and that of others, we recommend that you stop
the vehicle at a safe place and in accordancewith the traffic conditions before making or
accepting a phone call.
Comply with all legal requirements if you use
the telephone while driving. Use the hands-
free system and only use the telephone when
road, weather and traffic conditions permit. In
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). G
WARNING
If you switch off the ignition while driving,
safety-relevant functions are only available
with limitations, or not at all. This could affect, for example, the power steering and the brake
boosting effect. You will require considerably
more effort to steer and brake. There is a risk of an accident.
Do not switch off the ignition while driving.
Drive sensibly – save fuel Observe the following tips to save fuel:
X The tires should always be inflated to the
recommended tire pressure.
X Remove unnecessary loads.
X Remove roof carriers when they are not
needed.
X Warm up the engine at low engine speeds.
X Avoid frequent acceleration or braking.
X Have all maintenance work performed at
the service intervals specified in the Ser- 152
Driving tipsDriving and parking 

vice Booklet or indicated by the service
interval indicator.
Fuel consumption also increases when driv-
ing in cold weather, in stop-start traffic and in
hilly 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 judg-
ment.
The possibility of a serious or even fatal acci-
dent 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 tak-
ing drugs.
Pedals G
WARNING
Objects in the driver's footwell can restrict the pedal travel or obstruct a depressed pedal.
The operating and road safety of the vehicle is
jeopardized. There is a risk of an accident.
Make sure that all objects in the vehicle are
stowed correctly, and that they cannot enter
the driver's footwell. Install the floormats
securely and as specified in order to ensure
sufficient clearance for the pedals. Do not use loose floormats and do not place floormats on
top of one another.
Emission control G
WARNING
Inhalation of exhaust gas is hazardous to your health. All exhaust gas contains carbon mon-
oxide (CO), and inhaling it can cause uncon-
sciousness and possible death.
Do not run the engine in confined areas (such as a garage) which are not properly ventilated.
If you think that exhaust gas fumes are enter- ing the vehicle while driving, have the cause
determined and corrected immediately. If you
must drive under these conditions, drive only with at least one window fully open at all
times.
Certain engine systems are designed to keep
the level of poisonous components in exhaust fumes within legal limits.
These systems only work at peak efficiency if they are serviced exactly in accordance with
the manufacturer's specifications. For this
reason, all work on the engine should only be carried out by qualified and authorized
Mercedes-Benz technicians.
The engine settings must not be changed
under any circumstances. Furthermore, all
specific service work must be carried out at
regular intervals and in accordance with the
Mercedes-Benz service requirements. Details
can be found in the Maintenance Booklet. Braking
Important safety notes G
WARNING
If you activate the LOW off-road gear while
driving on a slippery road surface, the wheels may lose traction:
R if you remove your foot from the accelera-
tor pedal when driving
R if off road ABS intervenes when braking
If the wheels lose traction. the vehicle can no
longer be steered. There is an increased dan- ger of skidding and accidents.
Never activate the LOW off-road gear while
driving on a slippery road surface.
Downhill gradients !
On long and steep gradients, you must
reduce the load on the brakes by shifting
early to a lower gear. This allows you to take
advantage of the engine braking effect and Driving tips

use. Otherwise, you could suffer an electric
shock and be seriously or even fatally injured. G
WARNING
Any device that you connect must have a suit- able plug and meet U.S. standards. Never pull at a cable to disconnect a plug from a 115 V
AC power socket. Never use a damaged con-
nection cable. The 115 V AC power socket
must never be connected to another 115 V AC power source. Do not use a converter with anearthed plug for the 115 V AC power socket.
This could cause serious injury to you and/or
other people. G
WARNING
If the 115 V AC power socket is damaged or
pulled out of the trim, do not use or touch the 115 VAC power socket. The use of a 115 VAC
power socket that has been damaged or
pulled out of the trim could cause serious
injury to you or others. 115 V power socket
:provides an AC volt-
age of 115 Vso that small electronic devices
can be connected. These devices, such as
games consoles, chargers and laptops,
should not consume more than a maximum of 150 W altogether.
Requirements for operation of these devices:
R the 12 V sockets in the rear compartment
and the cargo compartment are opera-
tional (Y page 257).
R the plug of the electronic device is plugged
into 115 V power socket :.R
the on-board power supply is within a per-
missible voltage range.
R the electronic device's maximum power
output does not exceed 150 W.
X Open flap =.
X Switch on the ignition.
X Insert the plug of the electronic device into
115 V power socket :.
Indicator lamp ;lights up.
If indicator lamp ;does not light up,
please read the section on malfunctions.
X To turn off: disconnect the plug from 115 V
power socket :.
Ensure that you do not pull on the cord.
X Close flap =.
Possible causes of malfunctions:
R the on-board power supply is not within a
permissible voltage range.
R the temperature of the DC/AC converter is
temporarily too high.
R some small electronic devices have a con-
stant nominal power of less than 150 W,
but a very high switch-on current. In that
case, there is a possibility that these devi-
ces will not function properly as 115 V
socket :is not able to provide a high
enough current.
X If indicator lamp ;still does not light up,
contact a qualified specialist workshop. mbrace
