Notes on breaking-in a new vehicle
Important safety notes
New and replaced brake pads and discs only reach their optimum braking effect after several hundred kilometers of driving. Compensate for this by applying greater force to the brake pedal.
The first 1,000miles (1,500 km)
The more you look after the engine when it is new, the more satisfied you will be with its performance in the future.
RYou should therefore drive at varying
vehicle and engine speeds for the first 1,000 miles (1,500 km).
RAvoid heavy loads, e.g. driving at full
throttle, during this period.
RChange gear in good time, before the
tachometer needle is Ô of the way to the red area of the tachometer.
RDo not manually shift to a lower gear to
brake the vehicle.
RIf possible, do not depress the accelerator
pedal past the point of resistance (kickdown).
ROnly select shift ranges 3, 2 or 1 when
driving slowly, e.g. in mountainous terrain.
After 1,000 miles (1,500 km), you can increase the engine speed gradually and accelerate the vehicle to full speed.
Additional breaking-in notes for AMG vehicles:
RDo not drive faster than 85 mph
(140 km/h) for the first 1,000 miles (1,500 km).
ROnly allow the engine to reach a maximum
engine speed of 4,500 rpm briefly.
RChange gear in good time.
RIdeally, for the first 1,000 miles (1,500 km),
drive in program C.
i You should also observe these notes on breaking in if the engine or parts of the drive train on your vehicle have been replaced.
i Always observe the respective speed
limits.

166 Driving
When engaging transmission position D or R, always firmly depress the brake pedal and do not simultaneously accelerate.
X Depress the brake pedal and keep it
depressed.
X Shift the transmission to position D or
R(Y page 169).
X Release the brake pedal.
X Carefully depress the accelerator pedal.
The electric parking brake (Y page 184) is automatically released. The red F (USA only) or ! (Canada only) indicator lamp in the instrument cluster goes out.
i It is only possible to shift the transmission
from position P to the desired position if you depress the brake pedal. Only then is the parking lock released. If you do not depress the brake pedal, you can move the DIRECT SELECT lever but the parking lock remains engaged.
i The vehicle locks centrally once you have pulled away. The locking knobs in the doors drop down.
You can open the doors from the inside at any time.
You can also deactivate the automatic locking feature (Y page 280).
i Upshifts take place at higher engine
speeds after a cold start. This helps the catalytic converter to reach its operating temperature more quickly.
Pulling away with a trailer

Hill start assist
G WARNING After a short time, hill start assist will no longer brake your vehicle and it could roll away. There is a risk of an accident and injury.
Therefore, quickly move your foot from the brake pedal to the accelerator pedal. Never leave the vehicle when it is held by hill start assist.
X Remove your foot from the brake pedal.
The vehicle is then held for about a second.
X Pull away.
Hill start assist helps you when pulling away forwards or in reverse on an uphill gradient. It holds the vehicle for a short time after you have removed your foot from the brake pedal. This gives you enough time to move your foot from the brake pedal to the accelerator pedal and to depress it before the vehicle begins to roll.
Hill start assist will not function if:
Ryou are pulling away on a level road or on
a downhill gradient.
Rthe transmission is in position N.
Rthe electric parking brake is applied.
RESP® is malfunctioning.
