Please also observe the following breaking-innotes:
= With certain handling and driving safety sys-
tems, the sensors will adjust automatically
while a certain distance is being driven a"ser
the vehicle has been delivered or a"ser repairs.
Full system e"Mectiveness will be reached only
once this teach-in process has concluded.
= Brake pads, brake disks and tires that are
either new or have been replaced will achieve
optimum braking performance and grip only
a"ser several hundred kilometers of driving.
Compensate for the reduced braking e"Mect by
applying greater force to the brake pedal.
Notes on optimizing acceleration
If all necessary requirements and activation con-
ditions are ful"Nlled, the best possible acceleration
can be achieved from a standstill.
Do not use optimized acceleration on public
roads. Individual wheels could spin and you could
lose control of the vehicle. There is an increased risk of skidding and/or accident.
Be sure to observe the safety notes and informa-
tion on ESP n
( page 189).
Pulling away with optimized acceleration
&WARNING Risk of skidding and accidents
due to the wheels spinning
If you pull away using optimized acceleration,
individual wheels can spin and the vehicle can
skid.
There is an increased risk of skidding and
accidents, especially when ESP n
is switched
o"M!
Make sure that there are no persons or
obstacles in the vicinity of the vehicle.
Requirements
= the vehicle is run in (  page 154).
= the vehicle and tires are in good condition.
= the roadway has a high-grip surface.
= the engine and transmission are at normal
operating temperature.
*NOTE Increased wear due to optimized
acceleration
When pulling away with optimized accelera-
tion, all components of the drivetrain are sub-
jected to a very high load.
This can lead to increased component wear.
Do not always pull away with optimized
acceleration.Engage the [ drive position (  page 172).Move the steering wheel to the straight-ahead
position.Select the & drive program (  page 168).Deactivating ESP n
( page 191).Depress and hold the brake pedal "Nrmly with
your le"s foot.With your right foot, fully depress the acceler-
ator pedal.Driving and parking155

A"ser no more than "Nve seconds, take your le"s
foot quickly o"M the brake, but keep the accel-
erator pedal depressed.
The vehicle will pull away at maximum acceler-
ation.Switch on ESP n
once the acceleration proce-
dure is complete.
Ending optimized acceleration
Remove your foot from the accelerator pedal.Reactivate ESP n
.\bA"ser you pull away with optimized accelera-
tion, components of the drivetrain can
become very hot, which means that optimized
acceleration values may only be reached again a"ser a few minutes.
Notes on driving
&WARNING Risk of accident due to objects
in the driver\bs footwell
Objects in the driver\bs footwell may impede
pedal travel or block a depressed pedal.
This jeopardizes the operating and road safety
of the vehicle.Stow all objects in the vehicle securely so that they cannot get into the driver\bs
footwell.Always install the "Ooor mats securely
and as prescribed in order to ensure that
there is always su"Pcient room for the
pedals.Do not use loose "Ooor mats and do not
place "Ooor mats on top of one another.&WARNING Risk of accident due to incor-
rect footwear
Incorrect footwear includes, for example:
= Shoes with platform soles
= Shoes with high heels
= Slippers
There is a risk of an accident.
Always wear suitable footwear so that
you can operate the pedals safely.&WARNING Risk of accident if the vehicle is
switched o"M while driving
If you switch o"M the vehicle while driving,
safety functions are restricted or no longer
available.
This may a"Mect the power steering system and
the brake force boosting, for example.
You will need to use considerably more force
to steer and brake, for example.
Do not switch o"M the vehicle while driv-
ing.&DANGER Risk of death caused by exhaust
gases
Combustion engines emit poisonous exhaust
gases such as carbon monoxide. Inhaling
these exhaust gases is hazardous to health
and leads to poisoning.
Never leave the engine or, if present, the
auxiliary heating running in an enclosed
space without su"Pcient ventilation.156Driving and parking

&WARNING Risk of skidding and of an acci-
dent due to shi"sing down on slippery road
surfaces
If you shi"s down on slippery road surfaces to
increase the engine braking e"Mect, the drive
wheels may lose traction.
Do not shi"s down on slippery road surfa-
ces to increase the engine braking
e"Mect.&DANGER Risk of fatal injury due to poison-
ous exhaust gases
If the tailpipe is blocked or su"Pcient ventila-
tion is not possible, poisonous exhaust gases
such as carbon monoxide may enter the vehi- cle. This is the case, for example, if the vehicle
gets stuck in the snow.
Keep the tailpipe and the area around
the vehicle free from snow when the
engine or the stationary heater is run-
ning.Open a window on the side of the vehicle
facing away from the wind to ensure an
adequate supply of fresh air.&WARNING Risk of accident and injury due
to being under the in"Ouence of alcohol
and drugs while driving
Drinking and driving and/or taking drugs and
driving are very dangerous combinations. Even a small amount of alcohol or drugs can a"Mect
your re"Oexes, perceptions and judgment.
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 taking drugs.&WARNING Risk of accident due to the
brake system overheating
If you leave your foot on the brake pedal when
driving, the brake system may overheat.
This increases the braking distance and the
brake system can even fail.Never use the brake pedal as a footrest.Do not depress the brake pedal and the
accelerator pedal at the same time while
driving.*NOTE Engine damage due to excessively
high engine speeds
The engine will be damaged if you drive with
the engine in the overrevving range.
Do not drive with the engine in the over- revving range.*NOTE Wearing out the brake linings by
continuously depressing the brake pedalDo not depress the brake pedal continu-
ously whilst driving.To use the braking e"Mect of the engine,
shi"s to a lower gear in good time.Driving and parking157

*NOTE Damage to the drivetrain and
engine when pulling awayDo not warm up the engine while the
vehicle is stationary. Pull away immedi-
ately.Avoid high engine speeds and driving at
full throttle until the engine has reached
its operating temperature.*NOTE Damage to the catalytic converter
due to non-combusted fuel
The engine is not running smoothly and is mis-
"Nring.
Non-combusted fuel may get into the catalytic
converter.
Only depress the accelerator pedal
slightly.Have the cause recti"Ned immediately at
a quali"Ned specialist workshop.*NOTE Reduced battery life due to frequent
short-distance trips
The 12 V battery may not be su"Pciently
charged when the vehicle is used only for
short-distance trips. This reduces the life of
the battery.
Drive longer distances regularly to
charge the battery.*NOTE Damage to the vehicle due to not
observing the maximum permitted head-
room clearance
If the vehicle height is greater than the maxi- mum permitted headroom clearance, the roof
and other parts of the vehicle may be dam-
aged.
Observe the signposted headroom clear- ance.If the vehicle height is greater than the permitted headroom clearance, do not
enter.Observe the changed vehicle height with add-on roof equipment.\bPlease bear in mind that all the speed values
stated in this Operator\bs Manual are approxi-
mate and are subject to a certain tolerance.
Notes on driving with a roof load, trailer or fully laden vehicle
When driving with a loaded roof luggage rack or trailer as well as with a fully laden or fully occu-
pied vehicle, the vehicle\bs driving and steering
characteristics change.
You should therefore bear the following in mind:
= Do not exceed the permissible roof load and
towing capacity. Also observe the information
in the Technical Data.
= Distribute the roof load and the load inside the
vehicle evenly, placing heavy objects at the
bottom. Also comply with the notes on loading the vehicle (  page 109).
= Drive attentively, and avoid abrupt starts, brak-
ing and steering as well as rapid cornering.
