Before attempting to restart the engine:
X Turn the key back to position uin the ignition lock.
or X Press the Start/Stop button repeatedly until all indicator lamps on
the instrument cluster go out.
X Start the engine again (Y page 134). Avoid excessively long and
frequent attempts to start the engine, as this will drain the battery.
If the engine does not start after several attempts: X Consult a qualified specialist workshop. The engine does not
start. The starter motor
can be heard. The
reserve fuel warning
lamp is lit and the fuel
gauge display is at the
reserve level. The fuel tank is empty.
X Refuel the vehicle. The engine does not
start. You cannot hear
the starter motor. The on-board voltage is too low because the battery is too weak or
discharged.

Problem
Possible causes/consequences and
M
MSolutions The starter motor was exposed to excessively high thermal load.
X Start the engine again (Y page 134).
If the engine still does not start: X Consult a qualified specialist workshop. Vehicles with a petrol
engine:
The engine is not running
smoothly and is misfir-
ing. The engine electronics or a mechanical component of the engine
management system are/is malfunctioning.
X Depress the accelerator pedal only slightly.
Otherwise, non-combusted fuel may get into the catalytic converter
and damage it.
X Have the cause rectified immediately at a qualified specialist work-
shop. The coolant temperature
display is showing more
than 120 †. A display
message may also
appear on the multifunc-
tion display and a warn-
ing tone may sound. The coolant level is too low. The coolant is too hot and the engine is not
being cooled sufficiently.
X Stop as soon as possible and allow the engine and the coolant to
cool down.
X Check the coolant level (Y page 312). Observe the warning notes
as you do so and top up the coolant if necessary. If the coolant level is correct, the engine radiator fan may be faulty. The
coolant is too hot and the engine is not being cooled sufficiently.
X If the coolant temperature is below 120 †, you can continue driving
to the nearest qualified specialist workshop.
X Avoid heavy loads on the engine as you do so, e.g. driving in moun-
tainous terrain and stop-start traffic. DYNAMIC SELECT switch

Gear lever
! Only engage gear when the clutch pedal is
depressed.
! When shifting between
5thand 6thgear,
you should always push the gear lever all the
way to the right. Otherwise, you could shift
unintentionally into 3rdor4th gear and dam-
age the transmission. If you shift down at too high a speed (trans-
mission braking), this can cause the engine to
overrev, leading to engine damage.
Do not use the clutch bite point to keep the
vehicle stationary on uphill gradients. There is otherwise a risk of damaging the clutch.
! On long and steep downhill gradients, espe-
cially if the vehicle is laden or towing a trailer,
you must shift into gear 1, 2or3in good time.
This uses the engine's braking effect. This
relieves the load on the brake system and
prevents the brakes from overheating and
wearing too quickly. k
