Introduction

DEF (BlueTEC vehicles only)
Important notes on use To function properly, BlueTEC exhaus
tgas
aftertreatment must be operated with the
reducing agen tDEF. Adding DEF is one of the
tasks performed during maintenance. Under
normal operating conditions, a tank of DEF
lasts until the next service due date.
When the supply of DEF is almos tused up,
the Check Additive See Operator's Manual message is shown in the
multifunction display.
When the DEF supply sinks to a minimum
level, the Remaining Starts: 16 message
is shown in the multifunction display.
If the Remaining Starts: 16 message
appears in the multifunction display, you can
start the engine another 16 times. If DEF is
not added, it will then not be possible to
restart the engine. Refill the DEF tank with
approximately 1gal(3.8 l)of DEForh ave the
DE Ftank refilled at a qualified specialist
workshop.
Use the special DE Frefill bottle when filling
between maintenance intervals. Contact a
qualified specialist workshop with any
questions or, if necessary, contact Roadside
Assistance (Y page 22).
If the outside temperature is lower than
12 ‡ (Ò11) †, damage may occur when
adding DEF. If DEF is frozen and there is an
active warning indicator, it may not be
possible to add DEF. Park the vehicle in a
warmer place, e.g. in a garage, until DEFh as
become fluid again .Itwill the nbe possible to
add DEF again. Alternatively, have the DEF
tank refilled at a qualified specialist
workshop.
Further information about BlueTEC exhaust
gas aftertreatmen tand DEF is available at any
authorized Mercedes-Benz Center. Important notes on topping up G

General notes
Important safety notes G
WARNING
Always remembe rthat you must concentrate
primarily on driving the vehicle. The driver's
concentration must always be directed
primarily at road traffic. For your own safety
and that of others, we recommend that you
stop the vehicle at a safe place and in
accordance with 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-relevan tfunctions are only available
with limitations, or no tatall. 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 whe nthey are not
needed.
X Warm up the engine at low engine speeds.
X Avoid frequent acceleration or braking.
X Have all maintenance work carried out as
indicated by the service intervals in the
Maintenance Booklet or by the service
interval display.
Fuel consumption also increases when
driving in cold weather, in stop-and-go traffic
and in mountainous terrain. 168
Driving tipsDriving and parking

Drinking an
ddriving G
WARNING
Drinking and driving and/or taking drugs and
driving are very dangerous combinations.
Even a small amount of alcohol or drugs can
affec tyour 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.
Exhaust check G
WARNING
Combustion engines emit poisonous exhaust
gases such as carbon monoxide. Inhaling
these exhaust gases leads to poisoning. There
is a risk of fatal injury. Therefore never leave
the engine running in enclosed spaces
without sufficient ventilation.
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 must 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. Engine oil
! Vehicles with adiesel particle filter: if
the vehicle is predominantly used to travel
short distances, this can lead to
malfunctions in the automatic cleaning of the diesel particle filter. This can result in
fuel collecting in the engine oil and causing
engine failure. Therefore, if you frequently
drive short distances, make sure to drive
on highways or country roads for 20
minutes at least every 310 miles (500km).
Braking
Important safety notes G
WARNING
If you shift down on a slippery road surface in
an attempt to increase the engine's braking
effect, the drive wheels could lose their grip.
There is an increased danger of skidding and
accidents.
Do not shift down for additional engine
braking 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
helps avoid overheating and excessive
wear of the brakes.
When you take advantage of the engine
braking effect, a drive wheel may not turn
for some time, e.g. on a slippery road
surface. This could cause damage to the
drive train. This type of damage is not
covered by the Mercedes-Benzw arranty.
Do no tdepress the brake pedal continuously
while the vehicle is in motion, e.g. never
cause the brakes to rub by applying constant
slight pedal pressure. This results in
excessive and premature wear to the brake
pads.
Heavy and light loads G
WARNING
If you rest your foot on the brake pedal while
driving, the braking system can overheat .This Driving tips
169Driving and parking
Z

All checks and maintenance work on the
brake system must be carried ou
tata
qualified specialist workshop. Consult a
qualified specialist workshop to arrange this.
Have brake pads installed and brake fluid
replaced at a qualified specialist workshop.
If the brake system has only been subjectto
moderate loads, you should test the
functionality of yourb rakes at regular
intervals. To do so, press firmly on the brake
pedal when driving at a high speed. This
improves the grip of the brake pads.
You can find a description of Brake Assist
(BAS) on ( Ypage 68).
Mercedes-Benz recommends that you only
have brake pads/linings installed on your
vehicle which have been approved for
Mercedes-Benz vehicles or which correspond
to an equivalent quality standard .Brake
pads/linings which have not been approved
for Mercedes-Benz vehicles or which are not
of an equivalent quality could affect your
vehicle's operating safety.
Mercedes-Benz recommends that you only
use brake fluid that has been specially
approved for yourv ehicle by Mercedes-Benz,
or which corresponds to an equivalent quality
standard. Brake fluid which has not been
approved for Mercedes-Benz vehicles or
which is not of an equivalent quality could
affect your vehicle's operating safety.
Parking brake G
WARNING
If you must brake the vehicle with the parking
brake, the braking distanc eis considerably
longer and the wheels could lock. There is an
increased danger of skidding and accidents.
Only use the parking brake to brake the
vehicle when the service brake is faulty. Do
not apply the parking brake too firmly. If the
wheels lock, release the parking brake until
the wheels begin turning again.
If you brake the vehicle with the parking
brake, the brake lamps will not light up. If you drive on wet roads or dirt-covered
surfaces, road salt and/or dirt could get into
the parking brake.
In order to prevent corrosion and a reduction
in the braking power of the parking brake,
observe the following:
R
Gently depress the parking brake from time
to time before beginning the journey.
R Drive a distance of approximately 110 yds
(100 m) at a maximum speed of 12 mph
(20 km/h). Driving on wet roads
Hydroplaning If water has accumulated to a certain depth
on the road surface, there is a danger of
hydroplaning occurring, even if:
R
you drive at low speeds.
R the tires have adequate tread depth.
For this reason, in the event of heavy rain or
in conditions in which hydroplaning may
occur, you must drive in the following
manner:
R lower your speed.
R avoid ruts.
R brake carefully.
Driving on flooded roads !
Do not drive through flooded areas.
Check the depth of any water before driving
through it. Drive slowly through standing
water. Otherwise, water may enter the
vehicle interior or the engine compartment.
This can damage the electronic
components in the engine or the automatic
transmission. Water can also be drawn in
by the engine's air suction nozzles and this
can cause engine damage. Driving tips
