convertible top while driving. Do not drive
faster than 30 mph/50 km/h; otherwise, ve‐
hicle damage may occur.
▷ Do not attach any roof carrier systems; oth‐
erwise, an accident may occur.◀

Things to remember when driving
Breaking-in period
General information
Moving parts need to be broken in to adjust to
each other.
The following instructions will help achieve a
long vehicle life and good economy.
Engine and differential
Always obey the official speed limit.
Up to 1,200 miles/2,000 km
Do not exceed the maximum engine and road
speed:
▷
For gasoline engine, 4500 rpm and
100 mph/160 km/h.
Avoid full-throttle operation and use of the
transmission's kickdown mode for the initial
miles.
From 1,200 miles/2,000 km
The engine and vehicle speed can gradually be
increased.
Tires
Due to technical factors associated with their
manufacture,
tires do not achieve their full trac‐
tion potential until after an initial breaking-in pe‐
riod.
Drive conservatively for the first 200 miles/
300 km.
Brake system
Brakes require an initial break-in period of ap‐
prox. 300 miles/500 km to achieve optimized
contact and wear patterns between brake pads
and discs. Drive moderately during this break-in
period.
Clutch
The function of the clutch reaches its optimal
level only after a distance driven of approx. 300 miles/500 km. During this break-in period,
engage the clutch gently.
Following part replacement
The

same breaking in procedures should be ob‐
served if any of the components mentioned
above have to be renewed in the course of the
vehicle's operating life.
General driving notes
Closing the trunk lid
Drive with the trunk lid closed
Only drive with the tailgate closed; other‐
wise, in the event of an accident or braking or
evasive maneuvers, passengers or other road
users may be injured or the vehicle may be dam‐
aged. In addition, exhaust fumes may enter the
passenger compartment.◀
If driving with the tailgate open cannot be
avoided:
▷ If the convertible top is closed, close all win‐
dows.
▷ Greatly increase the blower speed.
▷ Drive moderately.
Hot exhaust system Hot exhaust system
High temperatures are generated in the
exhaust system.
Do not remove the heat shields installed and
never apply undercoating to them. When driv‐
ing,

standing at idle and while parking, take care
to avoid possible contact between the hot ex‐
haust system and any highly flammable materi‐
als such as hay, leaves, grass, etc. Such contact
could lead to a fire, and with it the risk of serious
personal injury as well as property damage.
Do not touch hot exhaust pipes; otherwise, there
is the danger of getting burned.◀ Seite 138
138 Online Edition for Part no. 01 40 2 606 521 - 03 11 490
Things to remember when driving

The heat generated in this process helps dry the
brake discs and pads.
In this way braking efficiency will be available
when you need it.
Hills
Drive
long or steep downhill gradients in the gear
in which the least braking is required. Otherwise,
the brake system may overheat, resulting in a
reduction in the brake system efficiency.
Manual transmission:
You can increase the engine's braking effect by
shifting down, going all the way to first gear, if
necessary.
Automatic transmission*:
You can increase the engine's braking effect by
shifting down in the manual mode of the auto‐
matic transmission, refer to page 72.
Avoid load on the brakes
Avoid placing excessive load on the brake
system. Light but consistent brake pressure can
lead to high temperatures, brake wear and pos‐
sibly even brake failure.◀
Do not drive in neutral
Do not drive in neutral or with the engine
stopped, as doing so disables engine braking. In
addition, steering and brake assist is unavailable
with the engine stopped.◀
Brake disc corrosion
Corrosion on the brake discs and contamination
on the brake pads are furthered by:
▷ Low mileage.
▷ Extended periods when the vehicle is not
used at all.
▷ Infrequent use of the brakes.
Corrosion occurs when the minimum pressure
that must be exerted by the pads during brake
applications to clean the discs is not reached.
Should corrosion form on the brake discs, the
brakes will tend to respond with a pulsating ef‐
fect that generally cannot be corrected. Condensation under the parked vehicle
When
using the automatic climate control, con‐
densation water develops that exits underneath
the vehicle.
Therefore, traces of condensed water under the
vehicle are normal.
Loading
Overloading the vehicle
To avoid exceeding the approved carrying
capacity of the tires, never overload the vehicle.
Overloading can lead to overheating and in‐
creases the rate at which damage develops in‐
side the tires. This could result in a sudden loss
of tire inflation pressure.◀
No fluids in the trunk
Make sure that fluids do not leak into the
trunk; otherwise, the vehicle may be damaged.◀
Determining the load limit 1.
Locate the following statement on your ve‐
hicle’s placard*:
▷The combined weight of occupants and
cargo should never exceed XXX kg or
YYY lbs. Otherwise, damage to the ve‐
hicle

and unstable driving situations may
result.
2. Determine the combined weight of the
driver and passengers that will be riding in
your vehicle.
3. Subtract the combined weight of the driver
and

passengers from XXX kilograms or YYY
pounds. Seite 140
