50 Getting startedDrivingStarting difficulties
If the engine does not start as described,
carry out the following steps:
If you are starting the engine with the
SmartKey, turn SmartKey in starter
switch to position0 and repeat starting
procedure.
If you are starting the engine with
KEYLESS-GO*: Close any doors that
may be open to allow for better detec-
tion of the SmartKey with
KEYLESS-GO*.
Or:
Start the engine with the SmartKey as
radio signals from another source may
be interfering with the SmartKey with
KEYLESS-GO*.
Repeat the starting procedure
(page 48).
Remember that extended starting at-
tempts can drain the battery.
Get a jump start (
page 456).If the engine does not start after several
starting attempts, there could be a mal-
function in the engine electronics or in the
fuel supply system.
Notify an authorized Mercedes-Benz
Center.
Parking brake
1Release handle
2Parking brake pedal
Release the parking brake by pulling on
release handle1.
The indicator lamp; (USA only)
or3 (Canada only) in the clock
goes out.
Warning!
G
When leaving the vehicle, always remove the
SmartKey or SmartKey with KEYLESS-GO*
from the starter switch, take it with you, and
lock the vehicle. Do not leave children unat-
tended in the vehicle, or with access to an
unlocked vehicle. Children could release the
parking brake, which could result in an acci-
dent and/or serious personal injury.
74 Safety and SecurityOccupant safetyRoll bars
The roll bars are integrated into the rear
head restraints.
The roll bars raise automatically in an acci-
dent or in a critical driving situation.You can manually lower the roll bars again
when the soft top is open (
page 424).
With the soft top closed, contact an autho-
rized Mercedes-Benz Center to have the
roll bars lowered. Do not attempt to lower
the roll bars manually with the soft top
closed. Lowering the roll bars manually
with the soft top closed may impair the
function of the roll bars.
Warning!
G
Make sure nothing is blocking the roll bars’
path of motion. Otherwise someone could
be injured when the roll bars are raised. The
head restraints should therefore always be
in the raised position when the rear seat is
occupied (
page 120).
iWhen the roll bars are raised automati-
cally, you will hear a ratcheting sound
and the rear head restraints will also
rise.
iYou cannot lower the rear head
restraints with the rear head restraint
lowering switch (
page 120) when the
roll bars are in the raised position.
Also, you cannot operate the soft top
using the soft top switch when the roll
bars are in the raised position.
If the soft top is open, you can man-
ually lower the roll bars
(page 424).
If the soft top is closed, contact an
authorized Mercedes-Benz Center
to have the roll bars lowered.
Warning!
G
If the yellow roll bar warning lamp in
the clock does not go out after starting the
engine, or if it comes on while driving, then
the roll bar system is not operating properly
and may not activate in an accident. In this
case, raise the roll bars manually before
continuing to drive (
page 423).
For safety reasons, drive only with the roll
bars raised until the malfunction is repaired.
Have your vehicle checked at an authorized
Mercedes-Benz Center.
