Warning!G
When leaving the vehicle, always remove the
SmartKey from the starter switch, take it
with you, and lock the vehicle. Do not leave
children unattended in the vehicle, or with
access to an unlocked vehicle. Children
could release the parking brake, which
could result in an accident and/or serious
personal injury.
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 mes-
sage
Release parking brake appears in the
multifunction display when driving off, you have
forgotten to release the parking brake.
Release the parking brake (
page 48).
iAt vehicle speeds of approximately 9 mph
(15 km/h), the automatic central locking system
engages and the locking knobs drop down.
The automatic door lock feature can be deacti-
vated (
page 143).
You can open a locked door from the inside.
Open door only when conditions are safe to do
so.
!Simultaneously depressing the accelerator
pedal and applying the brake reduces engine
performance and causes premature brake and
drivetrain wear.
!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.
