General notes
You can deactivate the flow of fresh air tem-
porarily if unpleasant odors are entering the
vehicle from outside or if you are driving
through a tunnel. The air already inside the
vehicle will then be recirculated.
If you switch on air-recirculation mode, the
windows can fog up more quickly, in partic-
ular at low temperatures. Only use air-recir-
culation mode briefly to prevent the windows
from fogging up.

Setting the air vents
Important safety notes
GWARNING
Very hot or very cold air can flow from the
air vents. This could result in burns or
frostbite in the immediate vicinity of the
air vents. There is a risk of injury.
Make sure that all vehicle occupants always
maintain a sufficient distance to the air
outlets. If necessary, redirect the airflow
to another area of the vehicle interior.
GWARNING
If you spray cleaning products or disin-
fectant into the ventilation system of the
vehicle, this could ignite. There is a risk
of fire.
Never spray these or any other substances
into the ventilation system. Always have
work on the ventilation system carried out
at a qualified specialist workshop.
In order to ensure the direct flow of fresh air
through the air vents into the vehicle inte-
rior, please observe the following notes:
Rkeep the air inlet between the service
cover and the windshield free of blockages,
such as ice, snow or leaves.
Rnever cover the air vents or air intake
grilles in the vehicle interior.
iFor optimum climate control in the vehi-
cle, open the air vents fully.

Parking brake
General notes
GWARNING
If you must brake the vehicle with the park-
ing brake, the braking distance is consid-
erably longer and the wheels could lock.
There is an increased danger of skidding
and accidents.
Only use the parking brake to brake the
vehicle when the service brake is faulty. Do
not apply the parking brake too firmly. If
the wheels lock, release the parking brake
until the wheels begin turning again.
GWARNING
If you leave children unsupervised in the
vehicle, they could set it in motion by, for example:
Rrelease the parking brake.
Rshift the automatic transmission out of
park position Por shift manual trans-
mission into neutral.
Rstart the engine.
In addition, they may operate vehicle
equipment and become trapped. There is a
risk of an accident and injury.
When leaving the vehicle, always take the
SmartKey with you and lock the vehicle.
Never leave children unsupervised in the
vehicle.
If you brake the vehicle with the parking
brake, the brake lamps will not light up.

chargers from a qualified specialist work-
shop.
Driving tips
General notes
Important safety notes
GWARNING
If you switch off the ignition while driv-
ing, safety-relevant functions are only
available with limitations, or not at all.
This could affect, for example, the power
steering and the brake boosting effect. You will require considerably more effort to
steer and brake. There is a risk of an acci-dent.
Do not switch off the ignition while driv-
ing.
GWARNING
If you operate mobile communication
equipment while driving, you will be dis-
tracted from traffic conditions. You could
also lose control of the vehicle. There is a
risk of an accident.
Only operate this equipment when the vehi- cle is stationary.
Observe the legal requirements for the coun-
try in which you are driving. Some jurisdic-
tions prohibit the driver from using a mobile
phone while driving a vehicle.
If you make a call while driving, always use
hands-free mode. Only use the telephone when
the traffic situation permits. If you are
unsure, pull over to a safe location and stop
before using the telephone.
Bear in mind that at a speed of only 30 mph
(approximately 50 km/h), the vehicle covers a
distance of 44 ft (approximately 14 m) per
second.
Drive sensibly – save fuel
Observe the following tips to save fuel:
RThe tires should always be inflated to the
recommended tire pressure.
RRemove unnecessary loads.
RWarm up the engine at low engine speeds.
RAvoid frequent acceleration or braking.
RHave all maintenance work carried out as
indicated by the service intervals in the
Maintenance Booklet or by the service
interval display.
Fuel consumption also increases when driv-
ing in cold weather, in stop-start traffic and
in hilly terrain.
Drinking and driving
GWARNING
Drinking and driving and/or taking drugs
and driving are very dangerous combina-
102Driving tips
>> Driving and parking.

tions. Even a small amount of alcohol or
drugs can affect your reflexes, perceptions
and judgment.
The possibility of a serious or even fatal
accident is greatly increased when you
drink or take drugs and drive.
Do not drink or take drugs and drive or
allow anyone to drive who has been drinkingor taking drugs.
Emission control
GWARNING
Combustion engines emit poisonous
exhaust gases such as carbon monoxide.
Inhaling these exhaust gases leads to poi-
soning. There is a risk of fatal injury.
Therefore never leave the engine running
in enclosed spaces without sufficient ven- tilation.
Certain engine systems are designed to keep
the level of poisonous components in exhaust
fumes within legal limits.
These systems only work at peak efficiency if
they are serviced exactly in accordance with
the manufacturer's specifications. There-
fore, only allow qualified and authorized
technicians to perform work on the engine.
The engine settings must not be changed
under any circumstances. Furthermore, all
specific service work must be performed at
regular intervals and in accordance with
smart service requirements. Details can be
found in the Maintenance Booklet.
Braking
Important safety notes
GWARNING
If you shift down on a slippery road surface
in an attempt to increase the engine's
braking effect, the drive wheels could lose
their grip. There is an increased danger of
skidding and accidents.
Do not shift down for additional engine
braking on a slippery road surface.
Downhill gradients
!On long and steep gradients, you must
reduce the load on the brakes by shifting to
a lower gear in good time. This allows you
to take advantage of the engine's braking
effect. This helps you to avoid overheating
the brakes and wearing them out exces-
sively.
When you take advantage of the engine's
braking effect, a drive wheel may not turn
for some time, e.g. on a slippery road sur-
face. This could cause damage to the drive
train, which is not covered by the smart
warranty.
Heavy and light loads
GWARNING
If you rest your foot on the brake pedal
while driving, the braking system can
overheat. This increases the stopping dis-
tance and can even cause the braking system
to fail. There is a risk of an accident.
Never use the brake pedal as a footrest.
Never depress the brake pedal and the
accelerator pedal at the same time.
!Depressing the brake pedal constantly
results in excessive and premature wear to
the brake pads.
If the brakes have been subjected to a heavy
load, do not stop the vehicle immediately.
Drive on for a short while. This allows the
airflow to cool the brakes more quickly.
Wet roads
If you have driven for a long time in heavy
rain without braking, there may be a delayed
reaction from the brakes when braking for the
first time. This may also occur after the vehi-
cle has been washed or driven through deep
water.
You then have to depress the brake pedal more
firmly. Maintain a greater distance from the
vehicle in front.
After driving on a wet road or having the
vehicle washed, brake firmly while paying
attention to the traffic conditions. This will warm up the brake discs, thereby drying them
