General notes
Running in
A new vehicle should be run in over
a
distance of
1,500 km. For the first 1,000 km the engine
speed should not exceed 2/3 of the maximum
permissible engine speed - do not use full throt
tle and do not tow a trailer or caravan. From
1,000 to 1,500 km you can gradually increase
the engine rpm and road speed.
During its first few hours of running, the internal
friction in the engine is greater than later on
when all the moving parts have bedded down.
How the vehicle is driven for the first 1,500 km
also influences the engine quality. After this
peri
od you should continue driving at moderate en
gine speeds, in particular when the engine is
cold.
This helps to reduce wear and tear on the
engine and increases the potential mileage which
can be covered by the engine.
You should also avoid driving with the engine
speed too low. Change down to a lower gear
when the engine no longer runs "smoothly". Ex
cessively high engine speeds are prevented by an
automatic rev limiter.
A WARNING
After driving through water, mud, sludge,
etc., the braking effect can be delayed slightly
due to moisture on the discs and brake pads.
Applying the brakes carefully several times
will remove the moisture and restore the full
braking effect.
© CAUTION
- Parts of the vehicle (e.g. engine, gearbox,
running gear or electrical components) can
be badly damaged when driving through
water.
- Always switch off the start/stop system*
^>page
79 before driving through water.
© ' Note
- It is advisable to check the depth at the
deepest point before approaching the wa
ter.
- Do NOT stop the vehicle, drive in reverse or
switch off the engine before you are out of
the water.
- Bear in mind that waves created by oncom
ing traffic could exceed the permissible
wading depth of your vehicle.
- Avoid driving through salt water (corrosion).
Avoiding damage to the car
© CAUTION
Take care not to damage
Low-mounted
parts
of the car (such as the spoiler or exhaust sys
tem) on steep ramps, uneven road surfaces or
roadside kerbs, etc. This applies especially to
vehicles with low ground clearance and to all
vehicles when fully laden.
Driving through water on roads
Please note the following in order to prevent
damage to the vehicle when driving through wa
ter (e.g. on flooded roads):
- The water level must not be higher than the ve
hicle's underbody.
- Do not drive faster than walking pace.
How to improve economy and minimise
pollution
Fuel economy, environmental impact and wear
on the engine, brakes and tyres depend largely
on the way you drive the vehicle. By adopting an
economical driving style and anticipating the
traffic situation ahead, you can reduce fuel
con
sumption by 10
-15
%. The following section
gives you some tips on Lessening the impact on
the environment and reducing your operating
costs at the same time.
Anticipate well in advance
A car uses most fuel when accelerating. If
you
an
ticipate hazards and speed changes well in ad
vance,
you will need to brake less and thus accel
erate Less. Wherever possible, Let the car slow
down gradually with a gear engaged, for •

Driving
A WARNING
- The driver should never get out of the
vehi
cle when the engine is running and a gear is
engaged.
If you have to leave your vehicle
while the engine is running, you must apply
the parking brake and engage the parking
lock P.
-If the engine is running and a gear is engag
ed (D/S or R) or the vehicle is in "tiptronic"
mode,
you will need to hold the car with the
footbrake. Otherwise, the car will "creep"
forwards as the power transmission is not
fully interrupted even when the engine is
idling.
- The accelerator pedal must on no account
be pressed inadvertently when the vehicle is
stationary. The vehicle could otherwise start
moving immediately (in some cases even if
the parking brake is engaged) and possibly
cause an accident.
- Do not press the accelerator while selecting
a gear with the vehicle stationary and the
engine running, as this could cause an
acci
dent.
- Never move the selector lever to R or P
when driving at normal speeds, as this could
cause an accident.
- Before you drive down a steep gradient, re
duce the speed and use "tiptronic" to select
a low gear.
- Never allow the brake to drag when driving
downhill and do not use the brake pedal too
often
or
for long periods. Constant braking
will cause the brakes to overheat and will
considerably reduce the effectiveness of the
brakes. It will increase the braking distance
and could cause the brake system to
fail.
- To avoid rolling back on gradients always
hold the vehicLe with the footbrake or park
ing brake if you have to stop.
- Never attempt to hold the vehicle with the
clutch when stopping on a gradient. The
clutch is disengaged automatically if it is
overloaded and becomes too hot - accident
risk! If the clutch is overloaded, the indica
tor lamp
0
will light up and a message will
appear
^>page
92.
© CAUTION
- When you have stopped on a gradient, do
not try to stop the vehicle rolling back by ac
celerating when a gear is engaged. This
could cause the automatic gearbox to over
heat and become damaged. Apply the park
ing brake or press the brake pedal in order
to prevent the vehicle from rolling back.
- If you allow the car to roll with the selector
lever in position N with the engine switched
off, the automatic gearbox will be damaged
as it will not be lubricated
^page
328,
Tow-starting / towing
away.
- In certain driving and traffic conditions, for
instance in stop-and-go traffic, if you have
to pull away frequently or if the vehicle
creeps forwards over a long distance, the
gearbox can overheat and become dam
aged.
If the indicator Lamp
[5J
or the warn
ing
lampH
Lights up, stop the vehicle at
the first opportunity and let the gearbox
cool down

© Note
For safety reasons the parking brake will only
release automatically if the driver's door is
closed.
Downhill speed control
Applies to: vehicles with automatic gearbox
The downhill speed control function helps the
driver when driving down steep gradients.
Downhill speed control is activated on a downhill
gradient when the selector lever is in D/S and the
driver presses the brake pedal. The gearbox auto
matically selects a suitable gear for the gradient.
The downhill speed control function attempts to
maintain the speed at which the vehicLe was trav
elling when the foot brake was applied (subject
to the laws of physics and technical limitations of
the power train). It may be necessary to adjust
the speed again using the foot brake. The down
hill speed control can change down to 3rd gear
but no further, so it may be necessary to change
to tiptronic mode on very steep gradients. In this
case,
change down manually to 2nd or 1st gear in •

Towing a trailer
Towing a trailer
Driving the vehicle with a
trailer or caravan
Technical requirements
The
towing bracket must comply with certain
technical requirements.
Your car is intended mainly for transporting pas
sengers and luggage. However, if suitably equip
ped,
it can also be used to tow a trailer or cara
van.
If the car is supplied with a factory-fitted towing
bracket it will already have the necessary techni
cal modifications and meet the statutory require
ments.
A 13-pin socket is provided to make the electrical
connection between the car and the trailer. If the
trailer you wish to tow has a 7-pin plug, the nec
essary adapter cable can be obtained from a spe
cialist retailer.
If
a
towing bracket is to be fitted after the car is
purchased,
this must be done according to the in
structions of the towing bracket manufacturer
^page
102.
A WARNING
If
a
towing bracket is retrofitted, the installa
tion should be carried out by
a
qualified work
shop.
- In particular in high outside temperatures it
is not possible to drive up long steep gradi
ents without
a
suitable cooling system. The
engine would then overheat.
- Incorrect installation can result in a safety
risk.
Points to check before towing
There are a number of points which need to be
checked before towing a trailer or caravan.
*•
Observe the maximum permitted trailer
weights
^>page
342.
Trailer weights
Never exceed the maximum permitted trailer
weights.
If
you
do not load the trailer up to the maximum
permitted trailer weight, you can then climb cor
respondingly steeper gradients.
The maximum trailer weights listed are only ap
plicable for altitudes up to 1000 m above sea
level.
With increasing altitude the engine power
and therefore the car's climbing ability are im
paired because of the reduced air density, so the
maximum trailer weight has to be reduced ac
cordingly. The weight of the car and trailer must
be reduced by about 10% for every further
1000 m (or part thereof). This figure refers to
the combined weight of the (loaded) vehicle and
(Loaded) trailer.
The figures for the draw bar weight that appear
on the identification plate of the towing bracket
are for certification purposes only. The correct
figures for your specific model, which may be
lower than these figures for the towing bracket,
are given in the registration documents and in
•=>
page 343.
Drive select*
Please note that the
efficiency*
mode is not
available in towing mode.
Exterior lights
Before starting
a
journey, make sure that all the
lights for the trailer are working properly.
Distributing the load
Distribute loads in the trailer so that heavy ob
jects are as near to the axle as possible. Loads
carried in the trailer must be secured to prevent
them slipping. A badly distributed load can also
affect handling. This can activate the trailer sta
bilisation feature and cause the vehicle to reduce
speed.
Where possible, operate the trailer with the max
imum permitted draw bar weight on the ball
joint of the towing bracket, but do not exceed the
specified limit. •
