Important safety notes
GWARNING
If children are left unsupervised in the vehicle,
they could:
Ropen the doors, thus endangering other
people or road users.
Rget out and disrupt traffic.
Roperate the vehicle's equipment.
Additionally, children could set the vehicle in
motion if, for example, they:
Rrelease the parking brake.
Rshifting the automatic transmission out of
park positionP
RStart the engine.
There is a risk of an accident and injury.
When leaving the vehicle, always take the
SmartKey with you and lock the vehicle. Never
leave children or animals unattended in the
vehicle. Always keep the SmartKey out of
reach of children.
GDANGER
Combustion engines emit poisonous exhaust
gases such as carbon monoxide. Inhaling
these exhaust gases is hazardous to health
and can result in poisoning. There is a risk of
fatal injury. Therefore, never leave the engine
running an enclosed space without adequate
ventilation.
GWARNING
Flammable materials introduced through
environmental influence or by animals can
ignite if in contact with the exhaust system or
parts of the engine that heat up. There is a risk
of fire.
Carry out regular checks to make sure that
there are no flammable foreign materials in
the engine compartment or in the exhaust
system.
General notes
The catalytic converter is preheated for up to30 seconds after a cold start. The sound of theengine may change during this time.

Driving and parking

For safety reasons, Mercedes-Benz recom-mends only installing the following brake disksand brake pads/linings:
Rbrake disks that have been approved byMercedes-Benz
Rbrake pads/linings that have been approvedby Mercedes-Benz or that are of an equivalentstandard of quality
Other brake disks or brake pads/linings cancompromise the safety of your vehicle.
Always replace all brake disks and brake pads/linings on an axle at the same time. Alwaysinstall new brake pads/linings when replacingbrake disks.
The vehicle is equipped with lightweight brakedisks to which the wheel assembly with rim andthreaded connection is matched.
The use of brake disks other than thoseapproved by Mercedes-Benz can change thetrack width and is subject to approval, if appli-cable.
Shock-type loads when handling the brakediscs, such as when changing wheels, can leadto a reduction in comfort when driving with light-weight brake discs. Avoid shock-type loads onthe lightweight brake disks, particularly on thebrake plate.
Mercedes-Benz recommends that you only usebrake fluid that has been specially approved foryour vehicle by Mercedes-Benz, or which corre-sponds to an equivalent quality standard. Brakefluid which has not been approved forMercedes-Benz vehicles or which is not of anequivalent quality could affect your vehicle'soperating safety.
Driving on wet roads
Hydroplaning
If water has accumulated to a certain depth onthe road surface, there is a danger of hydro-planing occurring, even if:
Ryou drive at low speeds
Rthe tires have adequate tread depth
For this reason, in the event of heavy rain or inconditions in which hydroplaning may occur,you must drive in the following manner:
Rlower your speed
Ravoid ruts
Ravoid sudden steering movements
Rbrake carefully
Driving on flooded roads
!Bear in mind that vehicles traveling in frontor in the opposite direction create waves. Thismay cause the maximum permissible waterdepth to be exceeded.
Failure to observe these notes may result indamage to the engine, electrical systems andtransmission.
If you have to drive on stretches of road on whichwater has collected, please bear in mind that:
Rin the case of standing water, the water levelmay be no higher than the lower edge of thevehicle body
Ryou should drive no faster than walking pace
Winter driving
GWARNING
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 brak-
ing on a slippery road surface.
GDANGER
If the exhaust pipe is blocked or adequate
ventilation is not possible, poisonous gases
such as carbon monoxide (CO) may enter the
vehicle. This is the case, e.g. if the vehicle
becomes trapped in snow. There is a risk of
fatal injury.
If you leave the engine or the auxiliary heating
running, make sure the exhaust pipe and area
around the vehicle are clear of snow. To
ensure an adequate supply of fresh air, open a
window on the side of the vehicle that is not
facing into the wind.
Have your vehicle winter-proofed at a qualifiedspecialist workshop at the onset of winter.
Drive particularly carefully on slippery road sur-faces. Avoid sudden acceleration, steering and

braking maneuvers. Do not use cruise control orActive Distance Assist DISTRONIC.
If the vehicle threatens to skid or cannot bestopped when moving at low speed:
XShift the transmission to position\\.
The outside temperature indicator is notdesigned to serve as an ice-warning device andis therefore unsuitable for that purpose.Changes in the outside temperature are dis-played after a short delay.
Indicated temperatures just above the freezingpoint do not guarantee that the road surface isfree of ice. The road may still be icy, especially inwooded areas or on bridges. The vehicle couldskid if you fail to adapt your driving style. Alwaysadapt your driving style and drive at a speed tosuit the prevailing weather conditions.
You should pay special attention to road condi-tions when temperatures are around freezingpoint.

Cruise control
General notes
Cruise control maintains a constant road speedfor you. It brakes automatically in order to avoidexceeding the set speed. Change into a lower
gear in good time on long and steep downhillgradients. This is especially important if thevehicle is laden or towing a trailer. By doing so,you will make use of the braking effect of theengine. This relieves the load on the brake sys-tem and prevents the brakes from overheatingand wearing too quickly.
Use cruise control only if road and traffic con-ditions make it appropriate to maintain a steadyspeed for a prolonged period. You can store anyroad speed above 20 mph (30 km/h).
Important safety notes
Cruise control can neither reduce the risk of anaccident if you fail to adapt your driving style noroverride the laws of physics. Cruise control can-not take into account the road, traffic andweather conditions. Cruise control is only anaid. You are responsible for maintaining a safedistance to the vehicle in front, for vehiclespeed, for braking in good time and for staying inlane.
Do not use cruise control:
Rin road and traffic conditions which do notallow you to maintain a constant speed, e.g. inheavy traffic or on winding roads
Ron slippery road surfaces. Braking or accel-erating could cause the drive wheels to losetraction and the vehicle could then skid
Rwhen there is poor visibility, e.g. due to fog,heavy rain or snow
If there is a change of drivers, advise the newdriver of the speed stored.
iThe speed indicated in the speedometermay differ slightly from the speed stored.
