Express opening and closing of sliding/pop-up roof
To select a sunroof opening position, press the switch to
resistance point and release it when the sunroof has
reached the required position.
The sliding/pop-up roof now opens to the position set if
the switch is pressed past resistance point in the “open”
direction.
If you wish to change the opening position of the
sunroof, move the switch to resistance point in the
direction you require.
Stopping the sliding/pop-up roof:
Move the switch in any direction.
If the movement of the sliding/pop-up roof is blocked
during the closing procedure, the sunroof will stop and
reopen slightly.
Note:
Opening the sliding/pop-up roof automatically almost
fully (less approximately 1 inch [3 cm]), the sunroof
must have been opened first by pressing the switch to
resistance point and releasing it when the sunroof has
reached an almost fully open position.

not operate if the sliding/pop-up roof is being
closed by moving the switch to its resistance point
and holding it there, or when using the electronic
main key or the lock button at each door handle
(vehicles with KEYLESS-GO).The closing procedure of the sliding/pop-up roof
can be immediately reversed by either moving the
switch in any direction, or pressing buttonŒon
the electronic main key and holding it; or (vehicles
with KEYLESS-GO) when carrying the KEYLESS-
GO-card, pull and hold a door handle.When leaving the vehicle, always remove the

Notes:
For improved recognition of the KEYLESS-GO-card the

The gear selector lever can only be moved with the
vehicle battery charged and connected, and the starter
switch in the Operation position. With the gear selector
lever in position “P”, the brake pedal must also be
depressed.Important!
For the KEYLESS-GO-system to function properly, the
operator should observe the following:
•If the KEYLESS-GO-card is positioned farther away
from the vehicle (e.g. inside clothing or a briefcase),
the vehicle cannot be locked (see page 40) or started
with the start-/stop button (see page 227).
•If the KEYLESS-GO-card is removed from the vehicle
while the engine is running, or by placing the card
in front of the center armrest (see page 190), the
message “CHIP-CARD – NOT RECOGNIZED!” will
appear repeatedly while driving in the
multifunction display, see page 38.

•Do not forget, the engine can be started by anyone if
a KEYLESS-GO-card is left inside the vehicle.
•To be able to operate the vehicle in the case of a
malfunction in the KEYLESS-GO-system (e.g. strong
radio frequency disturbance), we recommend that
you carry the electronic key plus mechanical key
with you and keep them in a safe place so that they
are always handy. Never leave the electronic key in
the vehicle.
•To avoid radio transmission interference, never store
the KEYLESS-GO-card together with other electronic
items (e.g. cellular telephones, other KEYLESS-GO-
cards) or metallic objects (e.g. coins, metal foil).Notes:
With the engine at idle speed, the charging rate of the
alternator (output) is limited.
It is therefore recommended that you turn off
unnecessary electrical consumers while driving in stop-
and-go traffic. This precaution helps to avoid draining of
the battery.
Unnecessary strain on the battery and charging system
may be minimized by turning off the following power
consumers, for example:
Heated seats, rear window defroster. In addition, the
automatic climate air volume control should be set to
the lowest position.

cluster displayPractical hints Car care Index Stopping
For brief stops, e.g. at traffic lights, leave the
transmission in gear and hold vehicle with the service
brake.
For longer stops with the engine idling, shift into “N”
or “P” and hold the vehicle with the service brake.
When stopping the vehicle on an uphill gradient, do not
hold it with the accelerator, use the brake. This avoids
unnecessary transmission heat build up.
Maneuvering
To maneuver in tight areas, e.g. when pulling into a
parking space, control the vehicle speed by gradually
releasing the brakes. Accelerate gently and never
abruptly step on the accelerator.
To rock a vehicle out of soft ground (mud or snow),
alternately shift from forward to reverse, while applying
slight partial throttle.Rocking a vehicle free in this manner may cause the
ABS or traction system malfunction indicator lamp to
come on. Turn off and restart the engine to clear the
malfunction indication.
Wa r n i n g !
Getting out of your vehicle with the selector lever
not fully engaged in position “P” is dangerous.
Also, when parked on an incline, position “P” alone
may not prevent your vehicle from moving,
possibly hitting people or objects.Always set the parking brake in addition to shifting
to position “P”, see page 238 for parking brake. When parked on an incline, also turn front wheel
against curb.Wa r n i n g !
When leaving the vehicle always remove the
electronic key from the starter switch, take the
KEYLESS-GO-card (if so equipped) with you and
lock the vehicle. Do not leave children unattended
in the vehicle, or with access to an unlocked
vehicle. Children could move the gear selector lever
from position “P”, which could result in an
accident or serious injury.
