WARNING
New brake pads/linings only have optimal
braking performance after several hundred
kilometres .Until then, compensate for this by
applying greate rforce to the brake pedal. This
also applies when brake pads/linings or
brake discs have been changed. The first 1,500 km
If you treat the engine with sufficient care
from the very start,y ou will be rewarded with
excellent performance for the remainder of
the engine's life.
R Drive at varying vehicle speeds and engine
speeds for the first 1,500 km.
R Avoid overstraining the vehicle during this
period, e.g. driving at full throttle.
R Change gear in good time, before the rev
counter needle is Ôof the way to the red
area of the rev counter.
R Do not shift down a gear manually in order
to brake. Vehicles with automatic transmission:

WARNING
Do not place any objects in the driver's foot-
well. If you use a floormat or carpet in the
driver's footwell, make sure that it is correctly
secured and that there is sufficient clearance
for the pedals.
Do not place several floormats on top of one
another.
Loose objects or the floormats could other-
wise get caught between the pedals if you
accelerate or brake suddenly. You will then
not be able to brake, declutch or accelerate
as intended. This could lead to accidents and
injury. G
WARNING
Do not change down for additional engine
braking on a slippery road surface. This could
cause the drive wheels to lose their grip and
the vehicle could skid. This could cause you
to lose control of your vehicle and cause an
accident.
! Warm up the engine quickly. Do not use
the engine's full performance until it has
reached operating temperature.
Only set the automatic transmission to the
respective drive positions when the vehicle
is stationary.

Problem Possible causes/consequences and
M Solutions
Vehicles with a petrol
engine:
The engine is not run-
ning smoothly and is
misfiring. There is a malfunction in the engine electronics or in a mechanical
component of the engine management system.
X
Only depress the accelerator pedal slightly.
Otherwise, non-combusted fuel may get into the catalytic con-
verter and damage it.
X Have the cause rectified immediately at a qualified specialist
workshop. The coolant tempera-
ture display is showing
more than 120 †. The
coolant warning lamp
may also be lit and a
warning tone may
sound. The coolant level is too low. The coolant is too hot and the engine
is no longer being cooled sufficiently.
X Stop as soon as possible and allow the engine and the coolant
to cool down.
X Check the coolant level (Y page 265). Observe the warning
notes as you do so and top up the coolant if necessary. If the coolant level is correct, the engine radiator fan may be faulty.
The coolant is too hot and the engine is no longer being cooled
sufficiently.
X If the coolant temperature is less than 120 †, you can continue
driving to the nearest qualified specialist workshop.
X Avoid heavy loads on the engine as you do so, e.g. driving on
mountain roads and stop-start traffic. Manual transmission

On long and steep downhill gradients,
especially if the vehicle is ladenort owing
a trailer, you must shift into gear 1, 2or3
in good time. This uses the engine's braking
effect .This relieves the load on the brake
system and prevents the brakes from over-
heating and wearing too quickly. Gear lever
