Risk of accident
New brake pads/lini ngso nly have optimal
braking performance after several hundred
kilome tres. Un tilt hen ,compensate for this by
applying greater force to the brake pedal. This
also applies when brake pads/linings or
brake discs have been changed. Th
ef irst 1500 km
The mor eyou look after the engin ewhen it is
new, the happier you will be with its perform-
anc eint he future.
R Therefore, drive at varying speeds and
engin espeeds for the first 1500 km.
R Avoi doverstrainin gthe vehicle during this
period, e.g. drivin gatfull throttle.
R Change gear in good time, at the latest
when the rev counter needle is 2
/ 3 of the
way to the red area in the rev counter dis-
play.
R Do not manually shift to alower gear to
brake the vehicle.
Vehicles with automatic transmission:
R If possible, do not depress the accelerator
pedal past the point of resistanc e(kick-
down).
R Only select shift ranges 3,2or 1whe ndriv-
ing slowly, e.g .inmountainou sterrain. Af
ter1 500 km, you may gradually bring the
vehicl euptof ull road and engine speeds.
i Also observe these running-in notes when
the vehicle's engine, front-axle transmis-
sion or differential have been replaced. Driving
Important safety notes
G
Risk of accident
Do not place any objects in the driver' sfoot-
well. If you use afloormat 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 object sorthe floormats coul dother-
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. Thi scould lead to accident sand
injury. G
Risk of accident
Do not chang edown for additional engine
brakin gonas lippery 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 performanc euntil it has
reache doperating temperature.
Only set the automatic transmission to the
respective driv eposition swhen the vehicle
is stationary.
Where possible, avoid spinnin gthe drive
wheels when pulling away on slippery
roads. Otherwise, you could damage the
drive train. 134

There is amalfunction in the engine electronics.
R There is amalfunction in the fuel supply.
R The on-board voltage is too low because the starter battery is

Problem Possible causes/consequences and
M Solutions
Vehicles with
apetrol
engine:
The engine is not run-
ning smoothly and is
misfiring. There is
amalfunction in the engine electronics or amechanical
componen tofthe engin emanagement system.
X Only depress the accelerator pedal slightly.
X Have the cause rectified immediately at aqualified specialist
workshop.
Otherwise, non-combusted fuel may get into the catalytic con-
verter and damage it. The coolant tempera-
ture display is showing
more than 120 †. The
coolant warning lamp
may also be lit and a
warning tone may
sound. (Y
page 192). The coolant level is too low. The coolant is too hot and the engine
is no longer being cooled sufficiently.
X
Stop as soo naspossible and allow the engin eand the coolant
to cool down.
X Check the coolant level (Y page261). Observe the warning
notes as you do so and top up the coolan tifnecessary. If the coolan
tlevel is correc t,the radiator fan may be faulty. The
coolant is too hot and the engine is no longe rbeing cooled suffi-
cien tly.
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 driving. Manual transmission

!
Whe nshifting between 5thand 6thgear,
you should always push the gear lever all
the way to the right. Otherwise, you could
shift uninte ntionally into 3rdor4th gear
and damage the transmission. Do not exceed the maximum speed for the
individual gears.
Shiftin
gdown at too high aspeed (trans-
mission braking) can cause the engine to
overrev ,leading to engine damage.
! On long and steep downhill gradients,
especiall yifthe vehicle is laden or towing
at railer, yo umust 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. Neutral
