To end this, you can either depress the accel-

ended automatically if:
R you manoeuvre to avoid the obstacle
R you drive slowe rthan approximately

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

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
