Pulling away
General notes
GWARNING
Vehicles with automatic transmission:
If the engine speed is above the idling
speed and you engage transmission posi-
tion Dor R, the vehicle could pull away
suddenly. There is a risk of an accident.
When engaging transmission position Dor
R, always firmly depress the brake pedal
and do not simultaneously accelerate.
!Vehicles with manual transmission:
change gear in good time and avoid spin-
ning the wheels. You could otherwise dam-
age the vehicle.
!Release the parking brake before driving
off. The parking brake can otherwise over-
heat, malfunction and wear out quickly.
Accelerate gently when pulling away.
The vehicle locks centrally once you have
pulled away.
You can open the doors from the inside at any
time.
You can also deactivate the automatic locking
feature (
Ypage 55).
Vehicles with automatic transmission: you
can only shift the transmission from position
P to the desired transmission position if:
Rthe ignition is switched on
Ryou depress the brake pedal and keep it
depressed and
Ryou press release button on the selector
lever (Ypage 92).
Only then is the shift lock released.
iVehicles with automatic transmission:
transmission shifts take place at higher
engine speeds after a cold start. This helps
the catalytic converter to reach its oper-
ating temperature more quickly.
Hill start assist
Hill start assist helps you when pulling away forwards or in reverse on an uphill gradient.
It holds the vehicle for a short time after you have removed your foot from the brake pedal.
This gives you enough time to move your foot
from the brake pedal to the accelerator pedal
and to depress it before the vehicle begins to
roll.
GWARNING
After a short time, hill start assist will no
longer brake your vehicle and it could roll

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.

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.

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.

Prevent water from entering the vehicle inte-
rior or the engine compartment. If you must
drive through standing water, bear in mind
that:
Rthe water level should not exceed the lower
edge of the vehicle body in still water
Ryou should drive no faster than at walking
pace.
Winter driving
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.
GDANGER
If the exhaust pipe is blocked or adequate
ventilation is not possible, poisonous
gases such as carbon monoxide (CO) may
enter the vehicle. This is the case, e.g. if
the vehicle becomes trapped in snow. There
is a risk of fatal injury.
If you have to leave the engine running,
keep the exhaust pipe and the area around
the vehicle free of snow. To ensure an ade- quate supply of fresh air, open a window on
the side of the vehicle that is not facing
into the wind.
Have your vehicle winterproofed at a quali-
fied specialist workshop at the onset of win-
ter.
Drive particularly carefully on slippery road
surfaces. Avoid sudden acceleration, steer-
ing and braking maneuvers. Do not use cruise
control.
If the vehicle threatens to skid or cannot be
stopped when moving at low speed:
XTry to bring the vehicle under control
using corrective steering.
XVehicles with automatic transmission:
shift the transmission to position N.The outside temperature indicator is not
designed to serve as an ice-warning device
and is therefore unsuitable for that purpose.
Changes in the outside temperature are dis-
played after a short delay.
Indicated temperatures just above the freez-
ing point do not guarantee that the road sur-
face is free of ice. The road may still be icy,
especially in wooded areas or on bridges.
You should pay special attention to road con-
ditions when temperatures are around freez-
ing point.
For more information on driving with snow
chains, see (
Ypage 179).
For more information on driving with summer
tires, see (
Ypage 179).
Observe the notes in the "Winter operation"
section (
Ypage 179).
Driving systems
Cruise control
General notes
Cruise control maintains a constant road
speed for you. Cruise control does not brake
the vehicle automatically. Only the engine's
braking effect is available. In order to
reduce speed and maintain distance to other
road users, you need to brake yourself. This
interrupts cruise control.
Use cruise control only if road and traffic
conditions make it appropriate to maintain a steady speed for a prolonged period. You can
use cruise control at speeds above 20 mph
(30 km/h).
Important safety notes
If you fail to adapt your driving style, cruise
control can neither reduce the risk of an
accident nor override the laws of physics.
Cruise control cannot take into account road,
weather or traffic conditions. Cruise control
is only an aid. You are responsible for the
distance to the vehicle in front, for vehicle
speed, for braking in good time and for stay-ing in lane.
