Climatronic automatically maintains a com-
fortable temperature. To do so, it automati-
cally regulates the supplied air temperature
and the blower and air distribution levels.
The system also allows for the effect of sun-
light, so there is no need for manual adjust-
ment. It also has a humidity sensor that
helps to automatically demist the wind-
screen.

● When mov in
g with the engine switched off,
the ignition key must always remain in posi-
tion 2
››› Fig. 172 ›
›› page 151 (ignition on).
The control lamps will light up in this posi-
tion. Otherwise, the steering lock could en-
gage suddenly. Risk of accident!
● Do not remove the key from the ignition un-
til the
vehicle has come to a standstill and is
secure (e.g. the handbrake is engaged). Oth-
erwise, the steering lock could suddenly en-
gage. Risk of accident!
● Always take the ignition key with you when
you le
ave the vehicle. This is particularly im-
portant if you leave children in the vehicle.
Children could, for example, start the engine
with the subsequent risk of accident.
● Never leave the engine running in unventi-
lated or c
losed rooms. The exhaust gases
contain carbon monoxide, an odourless and
colourless poisonous gas. Risk of fatal acci-
dents! Carbon monoxide can cause people to
lose consciousness and can cause death. ●
Never l e
ave the vehicle unattended if the
engine is running.
● Never switch the engine off until the vehi-
cle h
as come to a complete stop. Risk of acci-
dent! CAUTION
● Turnin g the s
teering wheel fully in either
direction when the vehicle is stationary and
the engine is in gear puts the power steering
under great stress. This could lead to noise.
Never leave the steering wheel turned fully in
either direction for more than 15 seconds.
Risk of damage to the power steering system!
● The starter motor may only be used (key
position 3
››› Fig. 172 ›
›› page 151 in the ig-
nition) if the engine is off. Using the starter
motor when the engine is running could dam-
age it.
● Immediately release the ignition key when
the engine st
arts, otherwise damage could be
caused to the starter motor.
● When the engine is cold, you should avoid
high engine speed
s, driving at full throttle
and over-loading the engine before it reaches
operating temperature. Risk of engine dam-
age!
● Do not tow-start the engine. Risk of engine
damag
e! In vehicles with a catalytic convert-
er, fuel that has not been burned could reach
the catalytic converter and catch fire in it.
This would lead to a fault in the catalytic con-
verter. You may use the battery from another » 149

● In the event of damage to the standard
front s
poiler or where a different front spoil-
er, wheel trims, etc. are subsequently fitted,
make sure the air vent to the brakes on the
front wheels is not blocked. Otherwise, brak-
ing operations may be impaired. Risk of acci-
dent!
● Always fully release the handbrake. If it is
only p
artially released, this will cause over-
heating of the rear brakes, which can impair
the function of the brake system. Risk of acci-
dent!
● Never leave children unsupervised in the
vehicl
e. They could release the handbrake or
move the gear lever. The vehicle could start
moving. Risk of accident!
● Insufficient fuel can cause the engine to run
irregu
larly or to switch off. Brake assist sys-
tems could be impaired. Risk of accident!
● Always adjust your driving style to suit visi-
bility
, the weather and road and traffic condi-
tions. The best vehicle safety offered by
brake assist systems must never encourage
you to run greater risks. Risk of accident! CAUTION
● Ob ser
ve the information concerning new
brake pads ››› page 161.
● Where braking is not necessary, do not
wear do
wn the brake pads by pressing down gently on the brake pedal. This causes the
brak
e
s to overheat, increasing their wear and
increasing braking distances.
● To ensure the brake assist systems work
properly, a
ll wheels must be fitted with tyres
approved by the manufacturer. Note
● If y
ou brake suddenly and the brake system
control unit regards the situation as hazard-
ous for the drivers behind you, the brake
lights will begin to flash automatically. After
reducing speed to approximately 10 km/h (6
mph) or stopping the vehicle, the brake lights
will stop flashing and the hazard warning
lights will switch on. The hazard warning
lights are automatically switched off when
you accelerate or restart the vehicle.
● On long, steep gradients, reduce your
speed and ch
ange to a lower gear (manual
gearbox) or move the selector lever to a lower
gear position (automatic gearbox). This uses
the force of the engine and the brakes do not
suffer as much. If you still have to brake, do
so intermittently, pressing down repeatedly
on the brake pedal.
● Vehicle modifications (e.g. to the engine,
brake
s, frame or a combination of wheels and
tyres) could impair the brake assist systems

example, if the vehicle begins to skid, the
E SC
br
akes the appropriate wheel automati-
cally.
The warning lamp on the general instru-
ment panel starts flashing when the system
is working.
The stability (ESC) system includes the fol-
lowing systems:
● Anti-lock brake system (ABS),
● Traction control system (TCS),
● Electronic differential lock (EDL),
● Hydraulic brake assist system (HBA),
● Hill hold control (HHC).
The ASR should be sw
itched on at all times.
Only under certain circumstances should the
system be switched off, e.g.
● driving with chains,
● driving in deep snow or on very soft surfa-
ces,
● D
uring the “swinging movement” required
to remo
ve a stuck vehicle
Switch the ASR back on as soon as possible.
Brake assist system (HBA)*
The HBA system is activated when you press
down on the brake pedal suddenly. It increa-
ses braking power, helping to reduce braking
distances. To reduce braking distance as
much as possible, keep the brake pedal pressed down firmly until the vehicle comes
to a st
andstill.
With the help of this system, the ABS is acti-
vated more quickly and more efficiently.
The brake assist function is deactivated auto-
matically when the brake pedal is released.
Hill hold control (HHC)*
The HHC system makes it easier to start the
vehicle on hills. The system maintains the
brake pressure created by pressing down on
the brake pedal for 2 seconds after it has
been released. Your foot can be removed
from the brake pedal and you can use the ac-
celerator pedal and move away on a hill with-
out having to use the handbrake. The brake
pressure drops as the accelerator pedal is
pressed. If the vehicle cannot be started, it
will start to move backwards after 2 seconds.
The HHC is activated on gradients of over
5%, if the driver door is closed. It only works
for starting on hills, moving both forward and
in reverse. It is not activated during start-up
down hill.
Control lamp
If the control lamp flashes, the ESC is
working.
If the warning lamp illuminates on igni-
tion, the ESC system may have switched off
due to technical reasons. Turn off the ignition and turn it on again. Upon switching on the
ignition again, if the w
arning lamp has
switched off, this means the ESC is function-
ing correctly again.
If the warning lamp is illuminated there is
a fault in the ESC.
The informative display indicates:
Report No.: electronic stability
control (ESC)
or Report No.: Traction control
system (ASR)
Go to a technical service. Note
If the battery is disconnected and connected
again, the y
ellow warning lamp lights up
when the ignition is switched on. This warn-
ing lamp must switch off after covering a
short distance. Anti-lock brake system (ABS)
The ABS system prevents the wheels locking
durin
g br
ak
ing. This helps the driver keep
control of the vehicle.
The driver is made aware of ABS assistance
by the pulsating of the brake pedal and a
characteristic noise. »

The engine can only be started in positions P
or N. If, on engaging the steering lock,
switching the ignition on/off or starting the
engine, the selector lever is not in these posi-
tions, the informative display will show Move

P/N is shown on the general
dash panel display.
At temperatures below -10°C (14°F), the en-
gine can only be started in position P.
Move the selector lever to position P when
parking the vehicle on a flat surface. On a
slope, the handbrake should be firmly ap- plied before moving the selector lever to the
park po
sition. This reduces the load on the
lock mechanism while making it easier to
move the selector lever from position P.
If, while the vehicle is moving, the selector
lever is accidentally moved to position N, re-
lease the accelerator and wait for the engine
to idle before moving it back into position. WARNING
● Never pr e
ss the accelerator when selecting
the automatic gearbox operating mode when
the vehicle is stationary. Risk of accident!
● Never move the selector lever to positions
R or P when driving. Ri
sk of accident!
● If the vehicle is to be stopped with a gear
selected and the en
gine idling (e.g. waiting
or moving slowly at traffic lights), press down
on the brake pedal because the transmission
is not entirely interrupted when the engine is
idling and the vehicle will tend to start mov-
ing.
● Apply the handbrake firmly and put the se-
lector l
ever in position P before opening the
bonnet and working on the vehicle with the
engine running. Risk of accident! Strictly fol-
low the safety instructions ››› page 202, En-
gine compartment.
● When stopping on a slope (hill), try not to
stop the
vehicle from moving by pressing the
“accelerator” with a gear selected. This could
overheat the clutch. If the clutch risks being
burnt due to this force, it would switch off and the vehicle could move backwards. Risk
of ac
c
ident!
● If you have to stop on a hill, press down on
the brake ped
al to stop the vehicle from mov-
ing.
● The drive wheels could lose traction on a
slipper

function is activated. Risk of sliding! CAUTION
● In D SG aut om
atic gearboxes, the double
clutch is protected from overloads. If the hill
hold control is used, the clutches are subjec-
ted to greater force if the vehicle is at a
standstill on a slope or suddenly accelerating
on a slope.

The first 1,500 km Over the first 1,500 kilometres the engine
mus
t
be run in.
Up to 1000 kilometres
– Do not drive at more than 3/4 of the maxi-
mum speed corr
esponding to the engaged
gear, i.e. up to 3/4 of the maximum permit-
ted engine speed.
– Do not drive at full speed.
– Avoid high engine speeds.
– Do not tow a trailer.
From 1000 t o 1500 k
ilometres (600 to 900
miles)
– Slowly increase the engine speed until
re
aching the maximum permitted speed of
the engaged gear, i.e. the maximum per-
mitted engine speed.
During its first few hours of running, the in-
ternal friction in the engine is greater than
later on, when all the moving parts have bed-
ded in. How the vehicle is driven over approx-
imately the first 1,500 kilometres (900
miles), determines the success of the proc-
ess of running in the engine. Even after running in, the vehicle should not
be unnece
ssarily driven at high engine
speeds. The maximum permitted engine
speed is marked at the start of the red zone
on the rev counter dial. The gear must be
changed up when the red area is reached in
vehicles with a manual gearbox. Extremely
high engine speeds when accelerating are
automatically limited, however the engine is
not protected against high engine speeds
produced by incorrectly changing to a lower
gear, which could cause the engine to run at
revs above the maximum permitted amount,
and consequently result in damage to the en-
gine.
Additionally, vehicles with a manual gearbox
must also bear the following in mind: do not
drive with the engine speed too low. Change
down to a lower gear when the engine no
longer runs smoothly. Observe the recom-
mendations for changing gear

New tyres
New tyres must be submitted to “running in”,
given that initially their grip is not yet at the
maximum level. During the first 500 km (120
