control over the vehicle, accidents and
serious or fa
tal injuries.
·
Never switch o the ignition while the
vehicle is in motion.
NOTICE
If the Auto StartStop system is used in very
high outside tempera
tures over a long peri-
od, the 12-volt vehicle battery can be dam-
aged.
·
Avoid using Auto StartStop at very high
outside temperatures.
In some cases, it may be necessary to
restart the engine manually. Follow
any c
orresponding messages on the instru-
ment cluster display.
Always deactivate the Auto StartStop
system manually when driving
through water.
Troubleshooting
Engine no l
onger starts automatically
Vehicles with eco-coasting function: If the
engine no longer starts automatically, the
warning Error: Vehicle energy system.
Please visit workshop may appear on the
instrument cluster display.
1. Start the engine manually → page 146.
2. Deactivate Auto StartStop manually
→ page 157.
3. Go to a suitably qualified workshop and
have the system checked.
Information on driving
General driving tips
Think ahead when driving
The average fuel consumption will increase
if you do not adopt a steady driving style.
Keeping a close eye on the trac can help
to avoid frequent acceleration and braking.
Keeping a sucient distance from the vehi-
cle in front will help you to think ahead
when driving.
Avoid driving at full throttle
The rolling and air resistance increase at
excessively high speeds. This in turn increa-
ses the force needed to move the vehicle.
Never make use of the vehicle’s top speed.
Observe the tyre pressures
A low tyre pressure does not just mean
greater wear, but also increases the rolling
resistance of the tyres and thus the aver-
age fuel consumption. Use optimised roll-
ing resistance tyres.
Adjust the tyre pressure according to the
vehicle load:
— Observe the information on the tyre pres-
sure sticker → page 350.
— Tyre Pressure Loss Indicator → page 356.
— Tyre Pressure Monitoring System
→ page 360.
Use low viscosity engine oils
Fully synthetic engine oils with low viscosi-
ty reduce frictional resistance in the engine
and spread better and more quickly, espe-
cially for cold starts.
WARNING
The engine power may be reduced at in-
crea
sing altitude due to the lower air den-
sity. Reduced engine power can lead to
accidents, e.g. when overtaking. This can
result in severe or fatal injuries.
·
Always adapt your speed and driving
style to the current visibility, weather
and road or trac conditions.
WARNING
Lack of attention in road tra
c can cause
accidents and serious or fatal injuries.
·
Always observe the current rules of the
road and speed limits and drive with an
anticipatory driving style.
·
Take regular breaks on long journeys –
at least every two hours.
WARNING
Alcohol, drugs, medication and narcotics
c
an severely impair perception, reaction
times and driving safety. This could cause
you to lose control of the vehicle. This
