112Using the system

Power steeringFirst read and observe the introductory information and safety warn-ings
on page 130.
The power steering enables you to steer the vehicle with less physical force.
The power steering only works when the engine is running. It is still fully possible to steer the vehicle if the power steering fails or if the en-gine is not running (e.g. when towing). However, greater physical effort is re-
quired to turn the steering wheel.
Starting and stopping the engine using the key
Introduction
This chapter contains information on the following subjects:
Electronic immobilizer

Stopping the engine
133
Starting and stopping the engine on vehicles with the KESSY system » page 133.
The engine can only be started using a correctly coded original key. The engine running noises may louder at first be louder for a short time afterstarting the cold engine. This is quite normal and is not an operating problem.
WARNING■ When driving, the ignition key must always be in the position 2 » Fig. 118 on
page 132 (ignition switched on) without the engine running. This position is
confirmed by the appearance of certain indicator lamps in the instrument clus-
ter. ■ If the key is not in position 2,
it could unexpectedly lock the steering -
danger of accident!
■
Only pull the ignition key from the ignition lock when the vehicle has come
to a complete stop (by applying the handbrake). Otherwise, the steering could
be blocked – risk of accident!
■
When leaving the vehicle, the ignition must always be removed. This is par-
ticularly important if children are left in the vehicle. Children could otherwise
start the engine for example – risk of accident or injury!
■
Never leave the vehicle unattended with the engine running.
■
Never switch off the engine before the vehicle is stationary – risk of acci-
dent!
WARNING■ Never leave the engine running in unventilated or closed rooms. The ex-
haust gases from the engine contain substances such as odourless and col-
ourless carbon monoxide (a poisonous gas) – risk to life! ■ Carbon monoxide can cause unconsciousness and death.
CAUTION
■The starter must only be operated when the engine is not running and the vehi-
cle is at a standstill. The starter or engine can be damaged if the starter is activa-
ted when the engine is running 3
» Fig. 118 on page 132.
■
Do not tow start the engine – there is a risk of damaging the engine and the
catalytic converter. The battery from another vehicle can be used as a jump-start
aid » page 234 , Jump-starting .
CAUTION
■
Avoid high engine revolutions, full throttle and high engine loads before the en-
gine has reached its operating temperature – risk of damaging the engine!■
Do not switch the engine off immediately at the end of your journey after the
engine has been operated over a prolonged period at high loads but leave it to
run at an idling speed for about 1 minute. This prevents any possible accumulation
of heat when the engine is switched off.
131Starting-off and Driving

For the sake of the environmentDo not warm up the engine while the vehicle is stationary. If possible, start your
journey as soon as the engine has started. Through this the engine reaches its operating temperature more rapidly and the pollutant emissions are lower.
Note
After switching off the ignition, the radiator fan may intermittently continue to
operate for approx. 10 minutes.
Electronic immobilizer
First read and observe the introductory information and safety warn-ings
on page 131.
An electronic chip is integrated in the head of the key. The immobiliser is deacti-
vated with the aid of this chip when the key is inserted in the ignition lock.
The electronic immobiliser is automatically activated when the ignition key is
withdrawn from the lock.
The engine will not start if a non-authorized ignition key is used.
The following message is shown in the information cluster display.
Immobilizer active.

Information messages
161
The START-STOP system helps you to save fuel while at the same time reducing
harmful exhaust emissions and CO 2 emissions.
The function is automatically activated each time the ignition is switched on. In the start-stop mode, the engine automatically switches to the vehicle's idle phase, e.g. when stopped at traffic lights. The engine restarts automatically
where necessary.
The system can work only if the following basic conditions are met. The driver's door is closed.
The driver has fastened the seat belt.
The bonnet is closed.The driving speed was higher than 4 km.h after the last stop.
No trailer is coupled.
WARNING■ The brake servo unit and power steering only operate if the engine is run-
ning.■
Never let the vehicle roll with the engine switched off.
CAUTION
Always deactivate the START-STOP system before driving through wa-
ter » page 148 .Note■
If the driver's seat belt is removed for more than approx. 30 seconds or the driv-
er's door is opened during stop mode on vehicles with manual transmission or au- tomatic transmission (when the selector lever in position P), the engine must be
started manually » page 133.■
After manually starting the engine on vehicles with manual transmission, auto-
matic engine shut down is not possible until the vehicle has travelled the re-
quired minimum distance for START-STOP mode.
■
If, on vehicles with automatic transmission, the selector lever positions D, S or N
are selected after driving in reverse, the vehicle will first need to achieve a speed
of over 10 km/h before automatic engine shut down can take place again.
■
Changes to the outdoor temperature can have an effect on the internal temper-
ature of the vehicle battery even after several hours. If the vehicle remains out-
doors for a long time in minus temperatures or in direct sunlight, it can take sev-
eral hours until the internal temperature of the vehicle battery reaches a suitable temperature for proper operation of the START STOP system.
■
If Climatronic is running in automatic mode, the engine may not switch off auto-
matically under certain conditions.

159Assist systems

The automatic start procedure takes place again. The warning symbol goes
out.
Further information on automatic transmission Engine shut down takes place when the selector lever is in positions P, D , S and N
and in Tiptronic mode.
When the selector lever is in position P, the engine remains shut down even after
you release the brake pedal. Start the engine by pressing the gas pedal or by moving the selector lever into a different mode and releasing the brake pedal.
If the selector lever is moved into position R during the STOP phase , the engine
will re-start.
No automatic engine shutdown takes place when the vehicle is moving at low speed (e.g. during a traffic jam or when tuning) and remains stationary after
pressing the brake pedal lightly. Automatic engine shutdown takes place if you
press the brake pedal down with more force.
Operating conditions of the system
First read and observe the introductory information and safety warn-ings
on page 159.
The START-STOP system is very complex. Some of the procedures are hard to check without servicing.
No engine shut down is carried out
Before each STOP phase, the system checks whether certain conditions have
been met. No engine shut down takes place in the following situations.
› The engine has not reached the minimum temperature for the START STOP
mode.
› The temperature inside the vehicle has not reached the temperature set in the
air-conditioning system.
› The external temperature is very low/high.
› The intensive windscreen heater (Climatronic) or windscreen heater/ventilation
is switched on with the maximum air temperature setting (manual air condition-
ing system).
› The parking aid/Park Assist is switched on.
› The charge state of the vehicle battery is too low.
› The stationary vehicle is on a steep slope or a steep downhill section.
› The idling speed is too high.
› The steering angle is too large (manoeuvring).
› The selector lever position
R is selected (e.g. when parking).
The warning symbol appears in the instrument cluster display.
The automatic start procedure takes place again
During the STOP phase, the engine fires up without any active driver intervention, e.g. in the following situations.
› The vehicle begins to roll, e.g. on a slope.
› The difference between the temperature setting of the air-conditioning system
and the inside temperature is too large.
› The intensive windscreen heater (Climatronic) or windscreen heater/ventilation
is switched on with the maximum air temperature setting (manual air condition-
ing system).
› The brake pedal was pressed several times (the pressure in the braking system
is too low).
› The charge state of the vehicle battery is too low.
› The current consumption is too high.
