(120°C). The coolant temperature may
climb to the red marking:

at high outside temperatures

Warning!
G
Driving when your engine is badly overheat-
ed can cause some fluids which may have
leaked into the engine compartment to
catch fire. You could be seriously burned.
Steam from an overheated engine can cause
serious burns and can occur just by opening
the engine hood. Stay away from the engine
if you see or hear steam coming from it.
Turn off the engine, get out of the vehicle
and do not stand near the vehicle until the
engine has cooled down.
!Avoid driving at excessive engine
speeds, as it may result in serious en-
gine damage that is not covered by the
Mercedes-Benz Limited Warranty.

Outside temperature indicator
When moving the vehicle into colder ambi-
ent temperatures (e.g. when leaving your
garage), you will notice a delay before the
lower temperature is displayed.
A delay also occurs when ambient temper-
atures rise. This prevents inaccurate tem-
perature indications caused by heat
radiated from the engine during idling or
slow driving.
Setting clock
Hour
Pull out right knob5 in the instrument
cluster (
page 20) and turn it counter-
clockwise.
Minutes

Pull out right knob5 in the instrument
cluster and turn it clockwise.
Warning!
G
The outside temperature indicator is not de-
signed to serve as an ice-warning device and
is therefore unsuitable for that purpose.
Indicated temperatures just above the freez-
ing point do not guarantee that the road sur-
face is free of ice. The road may still be icy,
especially in wooded areas or on bridges.
iTo adjust the time by a single hour or a
few minutes, turn knob5 just a few
degrees in the direction indicated for
hours or minutes.

92 Controls in detailManual transmission
Manual transmissionInformation on driving with a manual trans-
mission is found in the “Getting started”
section (
page 40).
Do not exceed the maximum speed in the
individual gears. Refer to tachometer
(
page 90) for engine speeds.
Shifting into reverse
Stop the vehicle completely.

Pull gearshift lever up and shift in
Rreverse.
Warning!
G
For vehicles equipped with a manual trans-
mission, getting out of your vehicle with the
gearshift lever not engaged in first or re-
verse gear and parking brake engaged is
dangerous. Also, when parked on an incline,
an engaged first or reverse gear alone may
not prevent your vehicle from moving, possi-
bly hitting people or objects.
Always set the parking brake in addition to
engaging first or reverse gear (
page 47).
When parked on an incline, turn front wheels
towards the road curb.
Do not park this vehicle in areas where com-
bustible materials such as grass, hay or
leaves can come into contact with the hot
exhaust system, as these materials could be
ignited and cause a vehicle fire.Warning!
G
When leaving the vehicle, always remove the
key from the steering lock, and lock the ve-
hicle. Do not leave children unattended in
the vehicle, or with access to an unlocked
vehicle. Children could move the gearshift
lever, which could result in an accident
and/or serious injury.
On slippery road surfaces as well as high en-
gine speeds, never downshift in order to ob-
tain braking action. This could result in drive
wheel slip and reduced vehicle control. Your
vehicle’s ABS will not prevent this type of
loss of control.
!Downshifting gears leading to overrev-
ving the engine can result in engine
damage that is not covered by the
Mercedes-Benz Limited Warranty.
Never hold the vehicle stopped on a hill
by using the clutch pedal. The clutch
may be damaged which is not covered
by the Mercedes-Benz Limited
Warranty.
Do not exceed the engine speed limits
(page 90).
