a risk of fire.
Carry out regular checks to make sure that
there are no flammable foreign materials
in the engine compartment or in the exhaust
system.
!Do not depress the accelerator when
starting the engine.
iDuring a cold start, the engine runs at
higher speeds to enable the catalytic con-
verter to reach its operating temperature.
The sound of the engine may change during
this time.

depressed.
XDepress the clutch pedal fully.
XShift to neutral.
Automatic transmission
XShift the transmission to position P
(Ypage 92).
The transmission position display in the
multifunction display shows P
(
Ypage 92).
iYou can start the engine in transmission
positions Pand N.
In order to start the engine in transmission
position Nyou must depress the brake pedal
and keep it depressed.
Starting procedure
XTurn the key to position 3in the ignition
lock (Ypage 87) and release it as soon as the

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

changes gear automatically. All
forward gears are available.
Driving tips
Changing gear
The automatic transmission shifts to the
individual gears automatically when it is in
transmission position D. This automatic
gearshifting behavior is determined by:
Rthe selected drive program:
Rthe position of the accelerator pedal
Rthe road speed
Accelerator pedal position
Your style of driving influences how the auto-
matic transmission shifts gear:
Rlittle throttle: early upshifts
Rmore throttle: late upshifts

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.
