80 Cornering light function (bi-xenon
headlamps*)
Specially designed headlamps light up the
area into which you are driving when turning
corners.
If you are driving at speeds below 40 km/h,
the cornering light function is activated either
by the turn signals or when the steering wheel
is turned. At speeds between 40 km/h and
70 km/h, only a steering wheel movement
activates the cornering light function. If you
are driving at speeds above 70 km/h the cor-
nering light function is deactivated.

G
Risk of accident
Do not keep any objects in the driver's foot-
well. If you use a floormat or carpet in the
driver's footwell, make sure that they are
correctly secured and that there is suffi-
cient clearance for the pedals.
Objects could otherwise get between the
pedals in the event of sudden braking or
acceleration. You may then no longer be
able to brake, change gear or accelerate as
intended. This may result in an accident and
injury. G
Risk of poisoning
Never leave the engine running in enclosed
spaces. The exhaust gases contain carbon
monoxide. Inhaling exhaust fumes consti-
tutes a health hazard and could lead to loss
of consciousness or even death.
! Do not depress the accelerator pedal
when starting the engine. i
If you depress the brake when starting the
engine, pedal travel will be unusually long
and there will be less pedal resistance.

X Release the parking brake (Y page 89). Automatic engine start (ECO start/
stop function*)
The ECO start/stop function automatically
switches on the engine as soon as you pre-
pare to pull away, e.g. by engaging a gear.
X Depress the clutch pedal.
The engine starts automatically.
X Shift to either first or reverse gear and pull
away.
! Do not engage a gear without depressing
the clutch as this disables the automatic
engine start function. As a result, the bat-
tery cannot be recharged and the demister
function of Thermotronic* is not available.
i When manoeuvring in and out of parking
spaces, the ECO start/stop function will
not automatically switch off the vehicle's
engine. The engine will only be switched off
automatically if the vehicle has reached a
speed of at least 15 km/h before coming
to a standstill again.
i The system can differentiate between
starting the engine with the key and the
automatic engine start via the ECO start/
stop function. Controls

Driving and pa
rking 88 Pulling away
! Warm up the engine quickly. Do not use
the engine's full performance until it has
reached operating temperature.
Only shift into reverse gear when the vehi-
cle is stationary.
Where possible, avoid spinning the drive
wheels when pulling away on slippery
roads. Otherwise, you could damage the
drive train.
i The vehicle locks centrally once you have
pulled away. The locking knobs in the doors
drop down.
You can open the doors from the inside at
any time.
You can also deactivate the automatic lock-
ing feature (Y page 110).
Manual transmission X
Depress the brake pedal.
X Depress the clutch pedal.
X Shift to either first or reverse gear.
X Release the parking brake (Y page 89).
X Slowly release the clutch pedal and
depress the accelerator pedal. !
Change gear in good time and avoid spin-
ning the wheels. Otherwise, you could dam-
age the vehicle.
AUTOTRONIC* i
It is only possible to move the selector
lever to the desired position if you depress
the brake pedal. Only then is the selector
lever lock released.
X Depress the brake pedal and keep it
depressed.
The selector lever lock is released.
X Release the parking brake.
X Move the selector lever to position Dor R.
i Wait until the shift process is completed
before pulling away.
X Release the brake pedal.
X Carefully depress the accelerator pedal.
i Upshifts take place at higher engine
speeds after a cold start. This helps the
catalytic converter to reach its operating
temperature more quickly. Hill start assist Hill start assist helps you when pulling away
on uphill gradients. It holds the vehicle for a
short time after you have removed your foot
from the brake pedal. This gives you enough
time to move your foot from the brake pedal
to the accelerator pedal and depress it before
the vehicle begins to roll.
G
Risk of accident
Never leave the vehicle when it is held by
hill start assist. After approximately one
second, hill start assist will no longer brake
your vehicle and it could roll away.
X Remove your foot from the brake pedal.
i Once you have taken your foot off the
brake pedal, the vehicle is held for around
one second.
X Pull away.
Hill start assist does not function if:
R you are pulling away on a level road or a
downhill gradient.

not steer the vehicle with the key removed.
Never leave children unsupervised in the
vehicle. They could release the parking
brake. This could lead to a serious or fatal
accident. G
Risk of fire

not under any circumstances come into
contact with easily ignitable material such
as dry grass or petrol. The material could
otherwise ignite and set the vehicle on fire. Parking brake 1

Risk of accident
If the engine is not running, there is no
power assistance for the steering and
brakes. Steering and braking will then
require significantly greater effort.
As a result, you might lose control of the
vehicle, cause an accident and injure your-
self and others.

Notes on the transmission
G
Risk of accident
The movement of the pedals must not be
impaired in any way. Do not keep any
objects in the driver's footwell. Make sure
that floormats or carpets are correctly
secured and that there is sufficient clear-
ance for the pedals. G
Risk of accident
Do not change down for additional engine
braking on a slippery road surface. This
could cause the drive wheels to lose their
grip and the vehicle could skid. This could
cause you to lose control of your vehicle
and cause an accident. Controls

braking will be required to prevent the vehi-

load on the brake system and prevents the
brakes from overheating and wearing too
