If the electric drive of the sliding door is
at risk of overheating, e.g. as a result of
frequent opening and closing within a
short amount of time, the sliding door
opens completely and is locked (func-
tion override). After approx. 30 seconds,
the sliding door is again operational.

tion (

2To open the sliding door
iFollowing a battery disconnection or
malfunction, it is necessary to fully
close the sliding door once by press-
ing and holding the switch on the
center console or in the doorway
(\2
page 93) and then to fully open
and close the door once by pressing
one of the switches briefly. This re-
stores normal operation of the slid-
ing door.
iIn the event of a malfunction or if the
battery is disconnected, you can dis-
connect the sliding door from the
electric drive via the unlocking me-
chanism and then open/close the sli-
ding door manually (

Do not accelerate to prevent your vehi-
cle from rolling backwards on an uphill
gradient. Instead, you should either use
the handbrake or depress the brake ped-
al. This prevents excessive wear on the
clutch.
Select a lower gear (shift range
3, 2 or
1)
(
\2
page 204) in good time on long and
steep downhill gradients, especially if
towing a trailer. This prevents the brakes
from overheating and wearing too rapidly.
It is best not to stop the vehicle immedi-
ately after the brakes have been subject-
ed to an extreme load; continue driving
for a short time instead. The brakes are
cooled down more quickly in the airflow.The first time the brakes are applied af-
ter a long period of driving in heavy rain
without braking, it is possible that:
\4
there will be a delayed braking
response
\4
you will need to depress the brake
pedal more firmly
You should therefore maintain a greater
distance from the vehicle in front.
BrakingWarning
G
There is no power assistance for the ser-
vice brake when the engine is not running.
You will need to use significantly more
force to brake and could therefore lose
control of the vehicle and cause an acci-
dent.
Never switch off the engine while driving.
Warning
G
Make sure that other road users are not
put at risk by your braking.

310 OperationDriving tips
4
If possible, do not brake abruptly, but
rather engage the brake slightly at first
to permit the trailer to activate its brake.
Then increase the braking force.Warning
G
Take into consideration that when towing
a trailer, the handling characteristics are
different and less stable from those when
operating the vehicle without a trailer.
It is important to avoid sudden maneu-
vers. Sudden maneuvers may lead to loss
of control over the vehicle-trailer combi-
nation. This could cause an accident re-
sulting in property damage or injury to
you or others.
!
CAUTION
If the transmission hunts between
gears on inclines, manually shift to a
lower gear (select
"4", "3", "2"
or
"1"). A lower gear and reduction
of speed reduces the chance of the
engine overloading and / or over-
heating.
When going down a long hill, shift
into a lower gear and use the en-
gine’s braking effect. Avoid riding the
brakes, thus overheating the vehicle
and trailer brakes.
If the engine coolant rises to an ex-
tremely high temperature (coolant tem-
perature needle approaching the red
zone) when the air conditioner is on,
turn off the air conditioner. Engine cool-
ant heat can be additionally vented by
opening the windows, switching the cli-
mate control fan speed to high and set-
ting the temperature control to the
maximum hot position.
Extreme care must be exercised since
your vehicle with a trailer will require ad-
ditional passing distance ahead than
when driving without a trailer. Because
your vehicle and trailer is longer than
your vehicle alone, you will also need to
go much farther ahead of the passed ve-
hicle before you can return to your lane.
