Driving precautions
Running-in
Moving parts need a certain time to achieve
maximum operating efficiency as a unit. Please
comply with the following instructions, which
are intended to ensure that your car achieves its
optimum operating life and economy.
Engine and final drive
Observe the national speed limits in the country
in which you are travelling.
Up to 2000 km, approx. 1200 miles
Drive at varying road and engine speeds, but do
not exceed the following values:
> Petrol engine
4500 rpm, or 160 km/h or 100 mph
> Diesel engine
3500 rpm, or 150 km/h or 90 mph
Avoid full throttle and do not use the automatic
transmission kick-down.
From 2000 km, approx. 1200 miles,
onwards
Engine and road speeds can be gradually
increased.
Sequential Manual Gearbox SMG
Do not use the acceleration assistant during
running-in, see page
61 .
Tyres
New tyres do not achieve their full road
grip immediately, for production reasons. You
should therefore drive in a restrained manner
for the first 300 km, approx. 200 miles.
Brake system
Brake pads and discs do not achieve a favoura-
ble wear and contact pattern until the car has
covered about 500 km, approx. 300 miles. Drive
with caution during this running-in period.
Clutch
The clutch needs to be run in for about 500 km,
approx. 300 miles, before it will operate with
maximum efficiency. Operate the clutch gently
while running it in.
After fitting new parts
The same running-in procedures should be
observed if any of the components mentioned
above have to be renewed in the course of the
car's operating life.
General driving notes
Closing the luggage compartment lid/
tailgate
Drive only with the luggage compartment
lid/tailgate fully closed, otherwise exhaust
gases could enter the passenger compart-
ment.
<
However, should you need to drive with the lug-
gage compartment lid/tailgate open:
1. Close all windows and the glass roof or pan-
orama glass roof.
2. Increase the air volume from the automatic
air conditioning considerably, see page
99
or 103 .
Hot exhaust system
High temperatures occur in the exhaust
system of all vehicles. Never remove the
head shields protecting this area, nor apply
underseal to them. Make sure that when the car
is driven or parked and when the engine is
idling, no easily flammable material such as hay,
leaves, grass, etc. comes into contact with the
hot exhaust pipe. It could ignite and cause a fire,
with the risk of severe injuries or damage.
