Vehicles with a petrol
engine:
The engine is not run-
ning smoothly and is
misfiring. There is a malfunction in the engine electronics or in a mechanical
component of the engine management system.
X
Only depress the accelerator pedal slightly.
Otherwise, non-combusted fuel may get into the catalytic con-
verter and damage it.
X Have the cause rectified immediately at a qualified specialist
workshop. The coolant tempera-
ture display is showing
more than 120 †. The
coolant warning lamp
may also be lit and a
warning tone may
sound. The coolant level is too low. The coolant is too hot and the engine
is no longer 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 265). 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 no longer being cooled
sufficiently.
X If the coolant temperature is less than 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 on
mountain roads and stop-start traffic. Manual transmission

WARNING
The movement of the pedals must not be
impaired in any way. Do not keep any objects
in the driver's footwell. Make sure that floor-
mats or carpets are correctly secured and
that there is sufficient clearance for the ped-
als.
Do not place several floormats on top of one
another. G
WARNING
Do not change down for additional engine
braking on a slippery road surface. This could
cause the drive wheels to lose their grip and
the vehicle could skid. This could cause you to lose control of your vehicle and cause an
accident.
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 damage 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. Manual transmission

!
On long and steep downhill gradients,
especially if the vehicle is ladenort owing
a trailer, you must shift into gear 1, 2or3
in good time. This uses the engine's braking
effect .This relieves the load on the brake
system and prevents the brakes from over-
heating and wearing too quickly. Gear lever

M is shown in the multifunction display.
Manual drive program Mis temporarily
active. Depending on which gearshift pad-
dle is pulled, the automatic transmission
immediately shifts into the next gear down
or up. i
When manual drive program Mis activa-
ted via the steering wheel gearshift pad-
dles, the temporarily active manual drive
program Mwill be deactivated automati-
cally after a limited time, if the driving sit-
uation permits. In this case, the automatic
transmission shifts into the automatic drive
program that was last engaged, i.e. Eor S.
When driving on downhill gradients, the
temporarily active manual drive program
M will only be deactivated if the accelerator
pedal is depressed while the vehicle is roll-
ing downhill.
Upshifting X
Pull the right-hand steering wheel gearshift
paddle (Y page 138).
The automatic transmission shifts up to the
next gear.
i If the maximum engine speed on the cur-
rently engaged gear is reached and you
continue to accelerate, the automatic
transmission automatically shifts up in
order to prevent engine damage.
Downshifting X
Pull the left-hand steerin gwheel gearshift
paddle (Y page 138).
The automatic transmission shifts down to
the next gear.
i If you brake the vehicle or stop without
shifting down, the automatic transmission
will shift down to a gear that will allow the
vehicle to accelerate or pull away again.
i For maximum acceleration, pull the left-
hand steering wheel gearshift paddle until
the transmission selects the optimum gear
for the current speed.
i If the engine exceeds the maximum
