Suitability of the seat
sfor attaching ISOFIXc hild restraint systemsIf you use
ababy car seat of category 0or0+orarearward-facing child restraint system of category
Ionar ear seat, you must adjust the driver's or front-passenger seat so that the seat does not touch
the child restraint system.
If you use acategory I, forward-facing child restraint system, you shouldr emove the head restraint
from the respective seat, if possible (Y page 70). The backrest of the child restraint system must,
as far as possible, lie flat against the backrest of the seat.
Alwayso bserve the notes in the "Child restraint system" section (Y page 40) and the child restraint
system manufacturer's installation instructions.
Make sure that the child's feet do not touch the front seat. If necessary ,move the front seat forward
slightly.
For certain child restraint systems in weight categories II or III, this can mean that the area of use
is restricted. The maximum size setting of the child restraint system may not be possible due to
possible contact with the roof.
When you remove the child restraint system, you must replace the head restraints again immedi-
ately (Y page 70). All vehicle occupants must adjust their head restraints correctly before begin-
ning the journey.

General notes i
Observ

tion (Y page 52).
ESP ®
monitors driving stability and traction, i.e.
power transmission between the tyres and the
road surface.
If ESP ®
detects that the vehicle is deviating from
the direction desired by the driver, one or more
wheels are braked to stabilise the vehicle. The
engine output is also modified to keep the vehi- cle on the desired course within physical limits.
ESP ®
assists the driver when pulling awayon
wet or slippery roads. ESP ®

4ETS traction control is part of ESP ®
.
4ETS traction control is no longer active above a
speed of approximately 60 km/h.
Traction control brakes the drive wheels indi-
vidually if they spin. This enables you to pull
awaya nd accelerate on slippery surfaces, e.g. if
the road surface is slippery on one side. In addi-
tion, more drive torque is transferred to the
wheel or wheels with traction.
Traction control remains active if you deactivate
ESP ®
