Vehicle data recording
Information regarding electronic
recording devices
(Including notice pursuant to California Code § 9951)
Please note that your vehicle is equipped with devices that can record vehicle systems data and, if equipped with the Tele Aid system,
may transmit some data in certain accidents.
This information helps, for example, to diagnose vehicle systems after a collision and to continuously improve vehicle safety.
DaimlerChrysler may access the information and share it with others
for safety research or vehicle diagnosis purposes
with the consent of the vehicle owner or lessee
in response to an official request by law enforcement or other government agency
for use in dispute resolution involving DaimlerChrysler, its affiliates or sales/service organization and/or
as otherwise required or permitted by law.
Please check the Tele Aid subscription service agreement for details regarding the information that may be recorded or transmitted
via that system.

Warning!G
On slippery road surfaces, never downshift
in order to obtain braking action. This could
result in drive wheel slip and reduced vehi-
cle control. Your vehicle’s ABS will not pre-
vent this type of loss of control.
!
If you hear a warning signal and the
message
Release parking brake ap-
pears in the multifunction display when
driving off, you have forgotten to re-
lease the parking brake.
!
Simultaneously depressing the acceler-
ator pedal and applying the brake re-
duces engine performance and causes
premature brake and drivetrain wear.
i
Once the vehicle is in motion, the auto-
matic central locking system engages
and the locking knobs drop down.
For more information, see “Automatic
central locking” (
page 103).

Do not run cold engine at high engine
speeds. Running a cold engine at high
engine speeds may shorten the service
life of the engine.
