Things to remember when driving
Break-in procedures
To ensure that your vehicle continues to
furnish optimized economy of operation
throughout an extended service life, we
request that you devote careful attention
to the following information.
Engine and differential
Up to 1,200 miles/2,000 km:
During this initial period you should attempt
to avoid constant, steady-state operation
and vary both vehicle and engine speeds
as often as possible. Until the break-in
period has been completed you should
also refrain from exceeding the following:
> 4,500 rpm or 105 mph/170 km/h
Always obey all official speed limits.
Avoid full-throttle operation and use of the
transmission's kick-down mode during
these initial miles.
Once you have driven 1,200 miles/
2,000 km, the engine or vehicle speeds can
be gradually increased.
Tires
Due to technical factors associated with
their manufacture, tires do not achieve their
full traction potential until after an initial
break-in period. Therefore, drive reservedly
during the first 200 miles/300 km.
Brake system
Brakes require an initial break-in period of
approx. 300 miles/500 km to achieve opti-
mized contact and wear patterns between
brake pads and rotors.
Following component replacements
Observe the break-in instructions again if
previously addressed components must be
replaced again during driving later.
General driving notes
Hot exhaust system
Extreme temperatures occur at the
catalytic converter on this and every
catalyst-equipped vehicle. Do not remove
the heat shields installed adjacent to vari-
ous sections of the exhaust system, and
never apply undercoating to them. When
driving, standing at idle and while parking
take care to avoid possible contact
between the hot exhaust system and any
highly flammable materials such as hay,
leaves, grass, etc. Such contact could lead
to a fire, accompanied by the risk of serious
property damage as well as personal
injury.
<
Air conditioning
Condensation forms in the air conditioner
system during operation, and then exits
under the vehicle. Traces of condensed
water under the vehicle are thus normal.
Before driving into a car wash
1. Fold in the exterior mirrors, refer to
page
53 , as otherwise they could be
damaged due to the width of the vehicle
2. Leave the remote control in the ignition
lock, as otherwise the P position of the
automatic transmission will automati-
cally be selected when the remote con-
trol is removed. Refer to page
63
and 69 .
With Comfort Access, be sure to
observe the instructions on page
63
3. Release the parking brake, especially
when you have activated Automatic
Hold. Refer to page
64 and 65 .
