GWARNING
During convenience opening, body parts
could be drawn in or become trapped

also switched on when a door is opened. This
means that slightly cooled air enters the vehi-
cle interior after the engine is started, to cool
the vehicle more rapidly.
Switching the residual heat function
on/off
General notes
Only vehicles with dual-zone automatic climate
control have the residual heat function.
Once the engine is switched off, it is possible to
make use of the residual heat of the engine to
continue heating or ventilating the front com-
partment of the vehicle for approximately
30 minutes. The heating or ventilation time
depends on the set interior temperature.

Starting the engine
Important safety notes
GWARNING
Combustion engines emit poisonous exhaust
gases such as carbon monoxide. Inhaling
these exhaust gases leads to poisoning. There
is a risk of fatal injury. Therefore never leave
the engine running in enclosed spaces with-
out sufficient ventilation.
!Do not depress the accelerator when start-
ing the engine.
XBefore starting the engine, make sure that:
Rall the doors are closed.
Rall the vehicle occupants are wearing their
seat belts correctly.
Rthe parking brake is applied.
iIf you depress the brake pedal before start-
ing the engine, the pedal travel may be shorter
and pedal resistance higher.
If you depress the brake pedal again after
starting the engine, pedal travel and resist-
ance will be back to normal again.

GWARNING
If the engine speed is above the idling speed
and you engage transmission position Dor R,
the vehicle could pull away suddenly. There is
a risk of an accident.
When engaging transmission position Dor R,
always firmly depress the brake pedal and do not simultaneously accelerate.
!Only shift into reverse gear when the vehicle
is stationary k. Otherwise, you could dam-
age the transmission.
XDepress the brake pedal and keep it
depressed.
The parking lock is released.
XShift the transmission to position hork.
On vehicles with a reverse warning feature,
when reverse gear kis engaged a warning
tone sounds to alert other road users
(
Ypage 125).
XRelease the parking brake (Ypage 136).
The F (only USA) or J(only Canada)
indicator lamp in the instrument cluster goes
out.
XRelease the brake pedal.
Hill start assist automatically maintains the
brake pressure for about another two sec-
onds after the brake pedal is released. This
makes it possible to pull away without the
vehicle immediately rolling back
(
Ypage 125).
XCarefully depress the accelerator pedal.
It is only possible to shift the transmission from
position jto the desired transmission position
if you d
epress the brake pedal. Only then is the
parking lock released. If the brake pedal is not
depressed, the DIRECT SELECT lever can still be
moved but the parking lock remains engaged.
The vehicle locks centrally once you have pulled
away. The locking knobs in the doors drop down.
You can open the doors from the inside at any
time.
You can also deactivate the automatic locking

Refueling
Important safety notes
GWARNING
Fuel is highly flammable. Improper handling of
fuel creates a risk of fire and explosion.
Avoid fire, open flames, smoking and creating
sparks under all circumstances. Switch off the
engine and, if applicable, the auxiliary heating
before refueling.
GWARNING
Fuel is poisonous and hazardous to health.
There is a risk of injury.
You must make sure that fuel does not come into contact with your skin, eyes or clothing
and that it is not swallowed. Do not inhale fuel
vapors. Keep fuel away from children.
If you or others come into contact with fuel,
observe the following:
RWash away fuel from skin immediately
using soap and water.
RIf fuel comes into contact with your eyes,
immediately rinse them thoroughly with
clean water. Seek medical assistance with-
out delay.
RIf fuel is swallowed, seek medical assis-
tance without delay. Do not induce vomit-
ing.
RImmediately change out of clothing which
has come into contact with fuel.
GWARNING
Electrostatic buildup can create sparks and
ignite fuel vapors. There is a risk of fire and
explosion.
Always touch the vehicle body before opening
the fuel filler flap or touching the fuel pump
nozzle. Any existing electrostatic buildup is
thereby discharged.
