GWARNING
If the child restraint system is installed incor-
rectly on a suitable seat, it cannot protect as
intended. The child cannot then be restrained
in the event of an accident, heavy braking or
sudden changes of direction. There is an
increased risk of injury, possibly even fatal.
Make sure that you observe the child restraint
system manufacturer's installation instruc-
tions and the notes on use. Please ensure,
that the base of the child restraint system is
always resting completely on the seat cush-
ion. Never place objects, e.g. cushions, under
or behind the child restraint system. Only use
child restraint systems with the original cover
designed for them. Only replace damaged
covers with genuine covers.
GWARNING
If the child restraint system is installed incor-
rectly or is not secured, it can come loose in
the event of an accident, heavy braking or a
sudden change in direction. The child
restraint system could be thrown about, strik-
ing vehicle occupants. There is an increased
risk of injury, possibly even fatal.
Always install child restraint systems prop-
erly, even if they are not being used. Make
sure that you observe the child restraint sys-
tem manufacturer's installation instructions.
You will find further information on stowingobjects, luggage or loads under "Loading guide-lines" (Ypage 278).
GWARNING
Child restraint systems or their securing sys-
tems which have been damaged or subjected
to a load in an accident can no longer protect
as intended. The child cannot then be
restrained in the event of an accident, heavy
braking or sudden changes of direction. There
is an increased risk of injury, possibly even
fatal.
Replace child restraint systems which have
been damaged or subjected to a load in an
accident as soon as possible. Have the secur-
ing systems on the child restraint system
checked at a qualified specialist workshop,
before you install a child restraint system
again.
The securing systems of child restraint systemsare:
Rthe seat belt system
Rthe LATCH-type (ISOFIX) securing rings
Rthe Top Tether anchorages

Driving tips
Changing gear
The automatic transmission shifts through theindividual gears automatically when it is in trans-mission position[. This automatic gear shift-ing behavior is determined by:
Rthe selected drive program
Rthe position of the accelerator pedal
Rthe road speed
Accelerator pedal position
Your style of driving influences how the auto-matic transmission shifts gear:
Rlittle throttle: early upshifts
Rmore throttle: late upshifts
Double-clutch function
When shifting down, the double-clutch functionis active regardless of the currently selecteddrive program. The double-clutch function
reduces load change reactions and is conduciveto a sporty driving style. The sound generated bythe double-clutch function depends on the driveprogram selected.
Kickdown
Use kickdown for maximum acceleration.
XDepress the accelerator pedal beyond thepressure point.The automatic transmission shifts to a lowergear depending on the engine speed.
XEase off the accelerator pedal once thedesired speed is reached.The automatic transmission shifts back up.
Gliding mode
Gliding mode is available depending on theequipment.
Gliding mode is characterized by the following:
RThe combustion engine is disconnected fromthe drive train.
RThe engine speed corresponds to the idlingspeed.
RThe multifunction display hides the gear indi-cator and displays transmission position[in green (Ypage 142).

Important safety notes
GWARNING
The automatic transmission switches to neu-
tral positionNwhen you switch off the engine.
The vehicle may roll away. There is a risk of an
accident.
After switching off the engine, always switch
to parking positionP. Prevent the parked vehi-
cle from rolling away by applying the parking
brake.
Vehicles with automatic transmission
XApply the electric parking brake.

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.
