 Careless use of the electric windows 
can cause severe injuries. 
- When locking the vehicle from the outside, 
make sure that nobody is inside the vehicle, 
as the windows cannot be opened from the 
inside in an emergency. 
© Note 
The windows can be operated for about ten 
minutes after the ignition has been switched 
off. The window switches are only deactivated 
when the driver's door or the front passeng

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 • 
72  
Page 75 of 364
Driving 
instance when you can see that the next traffic 
lights are red. This takes advantage of the engine 
braking effect, reducing wear on the brakes and 
tyres.
 Emissions and fuel consumption will drop 
to zero due to the overrun fuel cut-off. 
Change gear early to save fuel 
An effective way of saving fuel is to change up 
quickly through the gears. Running the engine at 
high rpm in the lower gears uses an unnecessary 
amount of
 fuel. 
Applies to: vehicles with manual gearbox 
Shift up to second gear as soon as possible. If 
possible, we recommend shifting up to the next 
gear at approx. 2,000 rpm. 
Applies to: vehicles with automatic gearbox 
Press the accelerator slowly and avoid using the 
"kick-down"
 feature. 
Avoid driving at high speed 
Avoid travelling at top speed. Fuel consumption, 
exhaust emissions and noise Levels all increase 
very rapidly at higher speeds. Driving at moder
ate speeds will help to save
 fuel. 
Do not let the engine idle for longer than 
necessary 
Engine idling periods are automatically reduced 
on vehicles with start/stop system*. On vehicles 
without a start/stop system, it is worthwhile 
switching off the engine at level crossings, for in
stance, or at traffic lights with a long red phase. 
The fuel saved after about 5 seconds can be 
greater than the amount of fuel needed to re
start a warm engine (the exact fuel saving de
pends on the engine version). 
The engine takes a very long time to warm up 
when it is running at idling speed. Mechanical 
wear and pollutant emissions are also especially 
high during this initial warm-up phase. It is 
therefore best to drive off immediately after 
starting the engine. Avoid running the engine at 
high speed. 
o
 Regular servicing 
Regular servicing can establish a basis for good 
iS
 fuel economy before you start driving. A
 well-
serviced engine gives you the benefit of im
proved fuel efficiency as well as maximum relia
bility and an enhanced resale value. A poorly 
maintained engine can consume up to ten per
cent more fuel than necessary. 
Avoid short trips 
The engine and emission control system need to 
reach their proper working temperature in order 
to minimise fuel consumption and emissions. 
A cold engine uses disproportionately more
 fuel. 
The engine only reaches its working temperature 
after about four kilometres, when fuel consump
tion will return to a normal level. 
Check tyre pressures 
Always make sure the tyres are inflated to the 
correct pressures
 •=>page
 306 to save
 fuel.
 If the 
tyre pressures
 are
 just 0.5
 bar
 too Low, this can 
increase the fuel consumption by as much as 5 
%. Due to the greater rolling resistance, under-
inflation also increases tyre wear and impairs 
handling. 
Do not use winter tyres all through the year; they 
will increase fuel consumption by up to 10 %. 
Avoid carrying unnecessary loads 
Every kilo of extra weight will increase the fuel 
consumption, so it is worth checking the Luggage 
compartment occasionally to make sure that no 
unnecessary loads are being transported. 
The roof carrier increases the air resistance of the 
vehicle and should be removed when not in use. 
This will save about 12 % of fuel at speeds of be
tween 60 and 75
 mph. 
Save electrical energy 
The engine drives the alternator to generate elec
tricity. This means that fuel consumption rises 
when more power is required for electrical equip
ment. Switch off electrical equipment when it is 
not needed. Electrical equipment which uses a 
lot of electricity includes the blower (at a high 
setting), the rear window heating and the seat 
heating*.

A WARNING 
- Never run the engine in confined spaces.

© CAUTION 
Avoid high engine speeds, full throttle and ex
treme load conditions until the engine has 
reached its normal operating temperature; 
otherwise this can damage the engine. 
© For the sake of the environmen 
Do not warm up the engine by running it with 
the car stationary. You should drive off imme
diately whenever possible. This will help avoid 
unnecessary exhaust emissions. 
© Note 
- If it is difficult to turn the ignition key to po

A,
 WARNING 
- Never switch off the engine until the vehicle 
is stationary. Otherwise you may not have 
the full benefit of the brake servo and pow
er steering. You may need more strength to 
steer and brake the vehicle than you nor
mally would. This would mean a greater risk 
of accidents and serious injury, because you 
cannot steer and brake in the normal
 man
ner. 
- Never remove the key from the ignition 
while the vehicle is moving. The steering 
lock could engage suddenly, and you would 
not be able to steer the car. 
- Always take the key with you when you leave 
the vehicle. Otherwise the engine can be 
started or power-operated equipment such 
as the electric windows can be used. This 
could result in serious injury. 
- When parking, always move the selector 
lever to position
 P
 to prevent the vehicle 
from rolling back accidentally. 
© CAUTION 
If the engine has been working hard
 fora
 long 
time,
 there is a risk of heat building up in the 
engine compartment after the engine has 
been switched off; this could cause engine 
damage. For this reason, you should Leave the 
engine idling for about 2 minutes before 
switching
 it
 off.
