For system-dependent automatic engine shutdown
to work, the following conditions must be 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.
Some additional conditions for the system to function correctly cannot be in-
fluenced or recognised by the driver. Therefore, the system can react differ-
ently in situations which are identical from the driver's perspective.
If after stopping the car, the message START-STOP NOT POSSIBLE appears in
the segment display or the MAXI DOT display shows the
» Fig. 108 warning
sign, then the conditions for automatic engine shut-down are not being met.
Running the engine e.g. is essential for the following reasons.
› The engine temperature for the proper function of the system has not yet
been reached.
› The charge state of the vehicle battery is too low.
› The current consumption is too high.
› High air-conditioning or heating capacity (high fan speed, big difference be-
tween the desired and actual interior temperature).
Note■ If the vehicle remains outdoors for a long time in minus temperatures or in
direct sunlight, it can take several hours until the internal temperature of the
vehicle battery reaches a suitable temperature for proper operation of the
START STOP system.■
If the driver's seat belt is removed for more than approx. 30 seconds or the
driver's door is opened during stop mode, the engine will have to be started
manually.
■
After the manual engine start and with a manual gearbox the automatic en-
gine shutdown can take place only when a minimum distance required for the
system function has been covered.

WARNING■Do not clamp the jump-start cable to the negative terminal of the dis-
charged battery. There is the risk of detonating gas seeping out of the bat-
tery being ignited by the strong spark resulting from the engine being star-
ted.■
The non-insulated parts of the terminal clamps must never touch each
other – there is a risk of short circuit!
■
The jump-start cable connected to the positive terminal of the battery
must not come into contact with electrically conducting parts of the vehicle
– there is a risk of short circuit!
■
Route the jump-start cables so that they cannot be caught by any rotat-
ing parts in the engine compartment.
■
There must not be any contact between the two vehicles, otherwise cur-
rent may flow as soon as the negative terminals are connected.
Towing the vehicle
Introduction

Braided tow rope / Spiral tow rope
This chapter contains information on the following subjects:
Front towing eye

Rear towing eye

Vehicles with a tow hitch
169
For towing a braided tow rope is to be used » Fig. 148-
.
When towing, the following guidelines must be observed.
Vehicles with manual transmission may be towed in with a tow bar or a tow
rope or with the front or rear wheels raised.
Vehicles with automatic transmission may be towed in with a tow bar or a tow
rope or with the front wheels raised. If the vehicle is raised at the rear, the au-
tomatic gearbox will be damaged!
Driver of the tow vehicle›
Engage the clutch gently when starting off or depress the accelerator partic-
ularly gently if the vehicle is fitted with an automatic gearbox.
›
Only then, approach correctly when the rope is taut.
The maximum towing speed is 50 km/h.
Driver of the towed vehicle
›
Switch on the ignition so that the steering wheel is not locked and so that
the turn signal lights, windscreen wipers and windscreen washer system can
be used.
›
Take the vehicle out of gear or move the selector lever into position N if the
vehicle is fitted with an automatic gearbox.
Please note that the brake servo unit and power steering only operate if the
engine is running. If the engine is not running, significantly more physical force
is required to depress the brake pedal and steer the vehicle.
If using a tow rope, ensure that it is always kept taught.
Both drivers should be familiar with the problems which might possibly occur while a vehicle is being towed. Unskilled drivers should not attempt to tow an-
other vehicle or to be towed in one.
The vehicle must be transported on a special breakdown vehicle or trailer if it
is not possible to tow the vehicle in the way described or if the towing dis-
tance is greater than 50 km.
WARNING■ When towing, respect the national legal provisions, especially those
which relate to the identification of the towing vehicle and the vehicle be- ing towed.■
When towing, exercise increased caution.
■
For towing no spiral tow rope is to be used » Fig. 148-
, the towing eye
may unscrew out of the vehicle - there is a risk of accidents.
■
The tow rope should not be twisted - there is a risk of accidents.
