four weeks, the battery may be damaged by
exhaustive discharging.
If you leave the vehicle parked for longer than
six weeks, the vehicle may suffer damage as a
result of lack of use.

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-

more quickly and protecting them against
corrosion.
Limited braking performance on salt-
treated roads
If you drive on salted roads, a layer of salt
residue may form on the brake discs and brake
pads. This can result in a significantly lon-
ger braking distance.
RBrake occasionally to remove any possible
salt residue. Make sure that you do not
endanger other road users when doing so.
RCarefully depress the brake pedal and the
beginning and end of a journey.
RMaintain a greater distance to the vehicle
ahead.
Servicing the brakes
!The brake fluid level may be too low, if:
Rif the red brake warning lamp lights up
in the instrument cluster and
Ryou hear a warning tone while the engine
is running
Observe additional warning messages in
the multifunction display.
The brake fluid level may be too low due to
brake pad wear or leaking brake lines.
Have the brake system checked immedi-
ately. Consult a qualified specialist work-
shop to arrange this.
!A function or performance test should
only be carried out on a 2-axle dynamome-
ter. If you wish to operate the vehicle on
such a dynamometer, please consult a
qualified specialist workshop in advance.
You could otherwise damage the drive train
or the brake system.
!As the ESP®system operates automati-
cally, the engine and the ignition must be
switched off (the SmartKey must be in posi-
tion 0or 1in the ignition lock) if:
Rthe parking brake is tested using a brake
dynamometer (maximum 10 seconds).
Rthe vehicle is towed with the front axle
raised.
Braking triggered automatically by ESP
®
may seriously damage the brake system. All checks and maintenance work on the brake
system must be carried out at a qualified
specialist workshop.
Have brake pads installed and brake fluid
replaced at a qualified specialist workshop.
If the brake system has only been subject to
moderate loads, you should test the function-
ality of your brakes at regular intervals.
When having brake pads/linings fitted, smart
recommends that you only use those which are
approved for smart vehicles or are of an
equivalent quality standard. Brake pads/
linings which have not been approved for
smart vehicles or which are not of an equiv-
alent quality could affect your vehicle's
operating safety.
smart recommends that you only use brake
fluid which is approved for smart vehicles or
is of an equivalent quality standard. Brake
fluid which has not been approved for smart
vehicles or which
is not of an equivalent
quality could affect your vehicle's operating
safety.
Driving on wet roads
Hydroplaning
If water has accumulated to a certain depth on the road surface, there is a danger of hydro-
planing occurring, even if:
Ryou drive at low speeds.
Rthe tires have adequate tread depth.
For this reason, in the event of heavy rain or in conditions in which hydroplaning may
occur, you must drive in the following man-
ner:
Rlower your speed.
Ravoid ruts.
Ravoid sudden steering movements
Rbrake carefully.
Driving on flooded roads
!Bear in mind that vehicles traveling in
front or in the opposite direction create
waves. This may cause the maximum per-
missible water depth to be exceeded.
Failure to observe these notes may result in damage to the engine, electrical systems
and transmission.
104Driving tips
>> Driving and parking.
The parking aid does not take into account
obstacles located:
Rbelow the detection range, e.g. people,
animals or objects
Rabove the detection range, e.g. overhang-
ing loads, truck overhangs or loading
ramps.
