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. 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.
Letting the engine warm up/cool down
Applies to: Sand RS models
You can reduce the amount of wear and tear on
your vehicle during a sporty driving session sim­
ply by adopting a more restrained driving style
while the engine is warming up and cooling
down.
When the engine is cold, the engine speed is limi­
ted so that the full range of engine power is not
available. Once the engine has reached operating
temperature, the rev Limit moves to a higher
range of engine speeds. In addition, the tyres will
not develop their full grip potential until they
have had a chance to warm up on the road.
Even though the engine continues to be cooled
after you switch it off, it is particularly important
to give it time to cool down before parking. The
engine, brakes, exhaust system and gearbox will
66 all
reach very high temperatures when you adopt
a sporty driving style. Before you park the vehi­
cle, allow it to cool down to normal temperature
by driving at moderate engine speeds for several
miles.
Avoiding damage to the car
CD 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.
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.
CD 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 71 before driving through water.
i Note
- It is advisable to check the depth at the
deepest point before approaching the wa­
ter.

CX) -
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).
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 en­
vironment 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 in­
stance when you can see that the next traffic
lights are red.
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. 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 start/stop system*, it is worthwhile
switching off the engine at level crossings, for in- Driving
stance, or at traffic lights with a long red phase.
The fuel saved after only 30 -40 seconds is
greater than the amount of fuel needed to re­
start the engine.
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.
Regular servicing
Regular servicing can establish a basis for good
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 percent more fuel than necessary.
Check the oil level when filling the tank. Oil con­
sumption depends to a great extent on the en­
gine load and engine speed. It is quite normal
that the oil consumption of a new engine only
reaches its lowest level after a certain mileage.
This means that the oil consumption can only be
properly assessed after about 5,000 km.
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 tyre pressures to save fuel. If the tyre
pressures are just 0.5 bar too low, this can in­
crease the fuel consumption by as much as 5 %.
Due to the greater rolling resistance, under-infla­
tion also increases tyre wear and impairs han­
dling.
67

Downloaded from www.Manualslib.com manuals search engine Driving
The tyre pressures should always be checked
when the tyres are cold.
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.
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*.
Steering Adjusting the steering wheel position
The height and reach of the steering wheel can
be adjusted as required to suit the driver.

CD CAUTION
If the engine has been working hard for a 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.
{(D Note
After the engine is stopped, the radiator fan
may remain on or turn itself back on for up to
10 minutes, even if the ignition is switched
off. This may occur for the following reasons:
- Residual heat has raised the coolant tem-
perature.
- Direct sunlight has additionally heated up
the engine compartment while the engine is
warm.
-Applies to vehicles with diesel particulate
filter: The emission control system is hot
because of the regeneration process, even
though the engine has not yet reached oper­
ating temperature.

In start/stop mode, the engine is switched off
automatically when the vehicle stops, e.g. at
traffic lights. The ignition remains on during this
stop phase. The engine is automatically started
on demand.
The start/stop system is automatically activated
each time you switch on the ignition.
Basic conditions for start/stop mode
- The driver's door must be closed.
- The driver's seat belt must be buckled.
- The bonnet must be closed.
- The vehicle must have been moving at over 4
km/h since the last stop.
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.
- Always take the key with you when leaving
the vehicle -even if you only intend to be
gone for a short time. This is especially im­
portant if children are left in the car. They
might otherwise be able to start the engine
or use power-operated equipment such as
the electric windows -this could lead to in­
juries.
- To avoid injury, make sure that the start/
stop system is switched off before working
in the engine compartment ¢page 73.
