hing it off.
● If the engine is cold, avoid high engine
speeds, p
ushing the engine too hard and rap-
id acceleration.
● Do not start the engine by pushing the ve-
hicle or t
owing it. Unburnt fuel could enter
the catalytic converter and damage it. Note
● Do not wait
until the engine warms up with
the vehicle stationary; if you have good visi-
bility through the windows, start driving im-
mediately. This helps the engine reach oper-
ating temperature faster and reduces emis-
sions.
● Electrical components with a high power
cons
umption are switched off temporarily
when the engine starts.
● When starting with a cold engine, noise
level
s may briefly increase. This is quite nor-
mal, and no cause for concern.
● When the outside temperature is below
+5°C (+41°F), if the en
gine is diesel, some
smoke may appear under the vehicle when
the fuel-operated auxiliary heater is on. Stopping the engine

Never switch off the engine while the vehicle
is mo
ving. This could cause loss of control of
the vehicle, accidents and serious injury.
● The airbags and belt tensioners do not
work when the ignition i
s switched off.
● The brake servo does not work with the en-
gine off. Ther
efore, you need to press the

● Power steering does not work when the en-
gine is not
running. You need more strength
to steer when the engine is switched off. ●
If the ignition i s
switched off, the steering
column could be locked, making it impossible
to control the vehicle. CAUTION
If the engine is made to work hard for a long
time, it ma
y overheat after being switched
off. To prevent damage to the engine before
switching it off, leave it idle for approx. 2 mi-
nutes in neutral. Note
After switching off the engine, the cooling fan
ma y
continue to operate in the engine com-
partment for a few more minutes, even with
the ignition off. The radiator fan is automati-
cally switched off. “My Beat” Function

Driving
● If the
v
ehicle is parked facing downhill,
turn the front wheels so that they point to-
wards the kerb .
● If the vehicle is parked facing uphill
, turn
the front wheels so that they point away from
the kerb.
● Secure the vehicle as usual by applying the
handbrak
e firmly and putting it in 1st gear. WARNING
● Tak e me
asures to reduce the risk of injury
when you leave your vehicle unattended.
● Never park where the hot exhaust system
coul
d ignite inflammable materials, such as
dry grass, low bushes, spilt fuel etc.
● Never allow vehicle occupants to remain in
the vehic
le when it is locked. They would be
unable to open the vehicle from the inside,
and could become trapped in the vehicle in
an emergency. In the event of an emergency,
locked doors will delay assistance to vehicle
occupants.
● Never leave children alone in the vehicle.
They cou
ld set the vehicle in motion, for ex-
ample, by releasing the handbrake or the
gearbox lever.
● Depending on weather conditions, it may
become extr
emely hot or cold inside the vehi-
cle. This can be fatal. Braking and stability systems
El ectr
onic
Stability Control (ESC)* This Electronic Stability System reduces the
risk
of
skidding and improves the vehicle's
stability and ability to hold the road.
The Electronic Stability Control (ESC) contains
the electronic differential lock (EDL) and the
traction control system (ASR). The ESC works
together with the ABS. Both control lamps
will light up if the ESC or ABS systems are
faulty.
The ESC system is started automatically
when the engine is started.
The ESC system is always active and cannot
be switched off. With the Easy Connect sys-
tem it is only possible to deactivate the ASR
or else select Sport mode.
The ASR can be deactivated when wheel spin
is desirable ›››
page 184.
For example:
● When driving with snow chains.
● When driving in deep snow or on loose sur-
fac e
s.
● When the vehicle is stuck, to rock it back-
ward
s and forwards.
Press the button to switch the ASR back on
when you no longer need wheel spin. Electronic Stability Control (ESC)*
The ESC r
educes the risk of skidding by brak-
ing the wheels individually.
The system uses the steering wheel angle
and road speed to calculate the changes of
direction desired by the driver, and constant-
ly compares them with the actual behaviour
of the vehicle. When irregularities occur, for
example, if the vehicle begins to skid, the
ESC brakes the appropriate wheel automati-
cally.
The forces acting on the braked wheel bring
the vehicle back to a stable condition. If the
vehicle tends to oversteer (the rear end
slides out), the system will act on the front
wheel on the outside of the turn.
Control lamp
There are two control lamps for the electronic
stability control. The lamp provides infor-
mation concerning function and disconnec-
tion status.
Both control lamps light up together when
the ignition is switched on and should turn
off after approximately 2 seconds. This is the
time taken for the function check.
This programme includes the ABS, EDL and
ASR. It also includes emergency braking as-
sistance (BAS). »

manent manual gear change using the
gearshift paddles, move the selector lever
from position D/S to the right.
When accelerating, the gearbox automatical-
ly shifts up into the next gear shortly before
the maximum engine speed is reached.
If you select a lower gear, the automatic gear-
box will not shift down until there is no risk of
over-revving the engine.
When the kick-down feature is used, the
gearbox shifts down to a lower gear, depend-
ing on road speed and engine speed.

Advice
Removing snow – Use a small brush to remove snow from the
windo
w
s and mirrors.
Removing ice – Use a de-icer spray.
Use a cl
ean cloth or chamois leather to dry
the windows. The chamois leathers used on
painted surfaces are not suitable to clean
windows because they are soiled with wax
deposits which could smear the windows.
If possible, use a de-icing spray to remove
ice. If you use an ice scraper, push it in one
direction only without swinging it.
Use window cleaner or a silicone remover to
clean rubber, oil, grease and silicone depos-
its off.
Wax deposits can only be removed with a
special cleaner available at your Technical
Service. Wax deposits on the windscreen
could cause the wiper blades to judder. Add-
ing a window cleaner that dissolves wax to
the windscreen washer fluid reservoir pre-
vents wiper blades from juddering, but the
wax deposits are not removed. CAUTION
● Never u se w
arm or hot water to remove
snow and ice from windows and mirrors. This
could cause the glass to crack! ●
The heatin g el
ement for the rear window is
located on the inner side of the window. To
prevent damage, do not put stickers over the
heating elements on the inside of the win-
dow. Cleaning windscreen wiper blades
Clean wiper blades improve visibility.
1. Use a soft cloth to remove dust and dirt
from the w ind
screen wiper blades.
2. Use window cleaner to clean the wind- scr
een wiper blades. Use a sponge or a
cloth to remove stubborn dirt.
Care of rubber seals If rubber seals are well looked after, they will
not
fr
eez
e so quickly.
1. Use a soft cloth to remove dust and dirt from the rubber seal
s.
2. Apply a specialist care product to the rub- ber seals.
The rubber s
trips on the doors, windows, etc.
will remain pliable and last longer if they are
treated with a suitable rubber care product
from time to time (for example silicone
spray). Caring for rubber seals will also prevent pre-
matur
e ageing and leaks. The doors will be
easier to open. If rubber seals are well looked
after, they will not freeze so quickly in winter.
Door lock cylinder The door lock cylinders can freeze up in win-
ter
.
T
o de-ice the lock cylinders you should only
use spray with lubricating and anti-corrosive
properties.
Cleaning chrome parts 1. Clean chrome parts with a damp cloth.
2. Polish chrome parts with a soft, dry cloth.
If
thi
s
does not provide satisfying results, use
a specialist chrome cleaning product.
Chrome cleaning products will remove stains
from the surface. CAUTION
To prevent scratching chrome surfaces:
● Never use an abrasive cleaning product on
chr ome.
● Do not

● Aft er fittin
g the temporary spare wheel,
check the tyre pressures as soon as possible.
Failure to do so may cause an accident. The
tyre pressure is listed on the back of the left
front door frame.
● Do not drive at over 80 km/h (50 mph)
when the temporar
y spare wheel is fitted on
the vehicle: risk of accident!
● Avoid heavy acceleration, hard braking and
fas
t cornering: risk of accident!
● Never use more than one temporary spare
wheel at the s
ame time, risk of accident.
● No other type of tyre (normal summer or
winter ty
re) may be fitted on the compact
temporary spare wheel rim. Winter service
W int
er ty
resIn winter conditions winter tyres will consid-
er
ab
ly
improve the vehicle's handling. The design of summer tyres (width, rubber com-
pound, tre
ad pattern) gives less grip on ice
and snow.
Winter tyres must be inflated to a pressure of
0.2 bar (2.9 psi/20 kPa) higher than the pres-
sures specified for summer tyres (see the
sticker on the back of the left front door
frame).
Winter tyres must be fitted on all four wheels.
Information on permitted winter tyre sizes
can be found in the vehicle's registration
documentation. Use only radial winter tyres.
All tyre sizes listed in the vehicle documenta-
tion also apply to winter tyres.
Winter tyres lose their effectiveness when the
tread is worn down to a depth of 4 mm.
The speed rating code ››› page 277, New
tyres and wheels determines the following
speed limits for winter tyres: ››› max. 160 km/h (99 mph)
m
ax. 180 km/h (112 mph)
m ax. 190 km/h (118 mph)
m
ax. 210 km/h (130 mph)
In some countries, vehicles which can exceed
the speed rating of the fitted tyre must have
an appropriate sticker in the driver's field of
view. These stickers are available from your
technical service. The legal requirements of
each country must be followed. Q
S
T
H Do not have winter tyres fitted for unnecessa-
rily lon
g periods. Vehicles with summer tyres
handle better when the roads are free of
snow and ice.
If you have a flat tyre, please refer to the
notes on the spare wheel ››› page 277, New
tyres and wheels . WARNING
The maximum speed for the winter tyres must
not be e x
ceeded. Otherwise, this could lead
to damage and risk of accident. For the sake of the environment
Fit your summer tyres again as soon as possi-
bl e.
They are quieter, do not wear so quickly
and reduce fuel consumption. 280
