In addition, children could set the vehicle in
motion, for example, if they:
R release the parking brake.
R change the transmission position.
R start the vehicle.
There is a risk of accident and injury.
Never leave children unsupervised in the
vehicle.
When leaving the vehicle, always take the
SmartKey with you and lock the vehicle.
Keep the SmartKey out of the reach of chil-
dren. G
WARNING
If persons, particularly children are subjec-
ted to prolonged exposure to extreme heat
or cold, there is a risk of injury, possibly
even fatal. Never leave children unattended
in the vehicle. G
WARNING
If the child restraint system is subjected to
direct sunlight, parts may get very hot. Chil-
dren may burn themselves on these parts,
particularly on the metal parts of the child
restraint system. There is a risk of injury.
If you leave the vehicle, taking the child with
you, always ensure that the child restraint
system is not exposed to direct sunlight.
Protect it with a blanket, for example. If the
child restraint system has been exposed to
direct sunlight, let it cool down before secur-
ing the child in it. Never leave children unat-
tended in the vehicle.
Make sure that all vehicle occupants have fas-
tened their seat belts properly and are seated
correctly. This is particularly important for chil-
dren.
Observe the safety notes on seat belts
(Y page
48) and the notes on the correct use
of the seat belt (Y page 49).
A booster seat may be necessary to achieve
proper seat belt positioning for children over
40 lbs (18 kg) until they reach a height where
a three-point seat belt fits properly without a
booster seat. Special seatbelt retractor
G
WARNING
If the seat belt is released while driving, the
child restraint system will no longer be
secured properly. The special seat belt
retractor is disabled and the inertia real
draws in a portion of the seat belt. The seat
belt cannot be immediately refastened.
There is an increased risk of injury, possibly
even fatal.
Stop the vehicle immediately, paying atten-
tion to road and traffic conditions. Reacti-
vate the special seat belt retractor and
secure the child restraint system properly.
All seat belts in the vehicle, except the driver's
seat belt, are equipped with a special seat belt
retractor. When activated, the special seat belt
retractor ensures that the seat belt cannot
slacken once the child seat is secured.
Installing a child restraint system:
X Make sure you observe the child restraint
system manufacturer's installation instruc-
tions.
X Pull the seat belt smoothly from the belt
outlet.
X Engage seat belt tongue in belt buckle.
Activating the special seat belt retractor:
X Pull the seat belt out fully and let the inertia
reel retract it again.
While the seat belt is retracting, you should
hear a ratcheting sound. The special seat
belt retractor is enabled.
X Push the child restraint system down so that
the seat belt is tight and does not loosen.
Removing the child restraint system and deac-
tivating the special seat belt retractor:
X Make sure you observe the child restraint
system manufacturer's installation instruc-
tions.
X Press the release button of the seat belt
buckle and guide the seat belt tongue back
towards the belt sash guide.
The special seat belt retractor is deactiva-
ted. Children in the vehicle

Important safety notes
In certain driving and driving safety systems,
the sensors adjust automatically while a cer-
tain distance is being driven after the vehicle
has been delivered or after repairs. Full system
effectiveness is not reached until the end of
this teach-in procedure.
New or replaced brake pads and brake discs
only reach their optimal braking effect after a
few hundred kilometers of driving. Until then,
compensate for this by applying greater force
to the brake pedal. The first 1000 miles (1500 km)
For the service life and economy of your vehi-
cle it is crucial that you break in the engine
with due care.
R Therefore, protect the engine for the first
1000 miles (1500 km

) by driving at varying
vehicle and engine speeds.
R Avoid overstraining the vehicle and high
engine speeds during this period, e.g. driv-
ing at full throttle. Do not exceed Ø of the
permissible maximum speed for each gear.
R Do not change down a gear manually in
order to brake.
R Try to avoid depressing the accelerator
pedal beyond the pressure point (kickdown).
After 1000 miles (1500 km), you can increase
the engine speed gradually and accelerate the
vehicle to full speed.
i You should also observe these notes on
breaking-in if the engine or parts of the drive
train on your vehicle have been replaced. Driving

WARNING
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. 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. G
WARNING
If the parking brake has not been fully
released when driving, the parking brake
can:
R overheat and cause a fire
R lose its hold function.
There is a risk of fire and an accident.
Release the parking brake fully before driv-
ing off.
! Warm up the engine quickly. Do not use
the engine's full performance until it has
reached operating temperature.
Only shift the automatic transmission to the
desired drive position when the vehicle is
stationary.
Where possible, avoid spinning the drive
wheels when pulling away on slippery roads.
You could otherwise damage the drive train. 126

Visual check of the vehicle exterior X
In particular, check the following compo-
nents on the vehicle, and on the trailer as
necessary:
R
license plates, vehicle lighting, turn sig-
nals, brake lamps and wiper blades for
dirt and damage
R tires and wheels for firm seating, correct
tire pressure and general condition
R trailer tow hitch for play and security
The trailer coupling is one of the most
important vehicle parts with regard to
road safety. Observe the notes on opera-
tion, care and maintenance of the trailer
tow hitch (see the manufacturer's operat-
ing instructions).
X Rectify any noticeable defects before com-
mencing the journey. Checks in the vehicle Emergency equipment/first-aid kit
X Check the equipment to make sure that it is
accessible, complete and ready for use.
The first aid and breakdown assistance equip-
ment is located:
R in the front door stowage compartments
R in the seat base of the left front seat
R in the rear stowage compartment on the
right-hand side of the vehicle

G
WARNING
Objects in the driver's footwell may restrict
the clearance around the pedals or block a
depressed pedal. This jeopardizes the oper-
ating and road safety of the vehicle. There is
a risk of an accident.
Stow all objects securely in the vehicle so
that they do not get into the driver's foot-
well. When using floormats or carpets, make
sure that they are properly secured so that
they do not slip or obstruct the pedals. Do
not place several floormats or carpets on
top of one another. G
WARNING
Unsuitable footwear can hinder correct
usage of the pedals, e.g.:
R shoes with thick soles
R shoes with high heels
R slippers
There is a risk of an accident.
Wear suitable footwear to ensure correct
usage of the pedals. Driving
