Driving and parking

=
V ehicles with automatic transmission: do not
depress the accelerator pedal beyond the
pressure point (kickdown).
= Only increase the engine speed gradually and
accelerate the vehicle to full speed aser
1,500 km.
This also applies when the engine or parts of the
drivetrain have been replaced.
Please also observe the following running-in
notes:
= In certain driving and driving safety systems,
the sensors adjust automatically while a cer-
tain distance is being driven aser the vehicle
has been delivered or aser repairs. Full sys-
tem eMectiveness is not reached until the end
of this teach-in process.
= Brake pads, brake discs and tyres that are
either new or have been replaced only achieve
optimum braking eMect and grip aser several
hundred kilometres of driving. Compensate for
the reduced braking eMect by applying greater
force to the brake pedal. Notes on driving

WARNING Risk of accident due t
o objects
in the driver's footwell
Objects in the driver's footwell may impede
pedal tr
avel or block a depressed pedal.
This jeopardises the operating and road safety
of the vehicle. 
Stow all objects in the vehicle securely
so t
hat they cannot get into the driver's
footwell.

he Ooor mats securely and as
prescribed in order to ensure that there
is always suPcient room for the pedals. 
Do not use loose Ooor mats and do no
t
place Ooor mats on top of one another. &
WARNING Risk of accident due t
o incor-
rect footwear
Incorrect footwear includes, for example: = shoes wit

h platform soles =
shoes wit
h high heels
= slippers
There is a risk of an accident.

DANGER Risk of f atal injuries due to
exhaust gases
Combustion engines emit poisonous exhaust
g
ases such as carbon monoxide. Breathing in
these exhaust gases is hazardous to health
and results in poisoning. 
Never leave the engine and, if present,
t

he stationary heater, running in an
enclosed space without suPcient venti-
lation. &
WARNING Risk of skidding and of an acci-
dent due t
o shising down on slippery road
surfaces
If you shis do
wn on slippery road surfaces to
increase the engine braking eMect, the drive
wheels may lose traction. 
Do not shis do
wn on slippery road surfa-
ces to increase the engine braking
eMect. &
DANGER Risk of f
atal injury due to poison-
ous exhaust gases
If the tailpipe is blocked or suPcient v
entila-
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
t

he vehicle free from snow when the
engine or the stationary heater is run-
ning. 
Open a window on the side of the vehicle
f

acing away from the wind to ensure an
adequate supply of fresh air. &
WARNING Risk of accident due t
o the
brake system overheating
If you leave your foot on the brake pedal when
dr
iving, 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
acceler
ator pedal at the same time while
driving. *
NOTE Engine damag
e due to excessively
high engine speeds The engine will be damaged if you drive with
t

he engine in the overrevving range. 
Do not drive with the engine in the over-
r
evving range. *
NOTE Causing w
ear to the brake linings by
permanently depressing the brake pedal 
Do not permanently depress the brake
pedal while dr

iving.

NOTE Damag e to the drivetrain and
engine when pulling away 
Do not warm up the engine while the
v

ehicle is stationary. Pull away immedi-
ately. 
Avoid high engine speeds and driving at
full t

hrottle until the engine has reached
its operating temperature. *
NOTE Damag
e to the catalytic converter
due to non-combusted fuel The engine is not running smoothly and is mis-
Nr

ing.
Non-combusted fuel may get into the catalytic
converter. 
Only depress the accelerator pedal
slightl

y. 
Have the cause r
ectiNed immediately at
a qualiNed specialist workshop. *
NOTE R
educed battery life due to frequent
short-distance trips The 12 V battery may not be
suPcientl
y
charged when the vehicle is used only for
short-distance trips. This reduces the life of
the battery. 
Drive longer distances regularly to
c

harge the battery. *
NOTE Damag
e to the vehicle due to not
observing the maximum permitted head-
room clearance If the vehicle height is greater than the maxi-
mum per
mitted 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
per
mitted headroom clearance, do not
enter. 
Observe the changed vehicle height with
add-on r
oof equipment. Notes on driving with a roof load, trailer or fully
laden v
ehicle
When driving with a loaded roof luggage rack or
trailer as well as with a fully laden or fully occu-
pied vehicle, the vehicle's driving and steering
characteristics change.
You should bear the following in mind:
= Do not exceed the permissible roof load and
towing capacity. Also observe the technical
data in the printed Owner's Manual.
= Evenly distribute the roof load, and place
heavy objects at the bottom. Also comply with
the notes on loading the vehicle
( page 121).
= Drive attentively, and avoid suddenly pulling
away, braking and steering as well as rapid
cornering.
Notes on driving on salt-treated roads
The braking eMect is limited on salt-treated roads. Driving and parking
175

Therefore, observe the following notes:
= due t
o salt build-up on the brake disks and
brakepads, the braking distance can increase
considerably or result in braking only on one
side
= maintain a much greater safe distance to the
vehicle in front
To remove salt build-up:
= brake occasionally while paying attention to
the traPc conditions
= carefully depress the brake pedal at the end of
the journey and when starting the next jour-
ney
Notes on aquaplaning
Aquaplaning can take place once a certain
amount of water has accumulated on the road
surface.
Observe the following notes during heavy precipi-
tation or in conditions in which aquaplaning may
occur:
= reduce speed
= avoid tyre ruts =
a void sudden steering movements
= brake carefully
% Also observe the notes on regularly checking
wheels and tyr

es ( page 379).
Notes on driving through water on the road sur-
f
ace
Water which has entered into the vehicle can
damage the engine, electrics and transmission.
Water can also enter the air intake of the engine
and cause engine damage.
Observe the following if you must drive through
water:
= The water, when calm, may only reach the
lower edge of the vehicle body.
= Drive at a maximum speed of 10 km/h; water
can otherwise enter the vehicle interior or
engine compartment.
= Vehicles travelling in front, or oncoming vehi-
cles, can create waves which may exceed the
maximum permissible depth of the water.
The braking eMect of the brakes is reduced aser
fording. Brake carefully while paying attention to the
tr
aPc conditions until braking power has been
fully restored. ECO start/stop function
