GWarning!
The ABS cannot prevent the natural laws of
physics from acting on the vehicle, nor can
it increase braking or steering efficiency
beyond that afforded by the condition of the
vehicle brakes and tires or the traction
afforded. The ABS cannot prevent
accidents, including those resulting from
excessive speed in turns, following
another vehicle too closely, or
hydroplaning. Only a safe, attentive, and
skillful driver can prevent accidents. The
capabilities of an ABS equipped vehicle
must never be exploited in a reckless or
dangerous manner which could jeopardize
the user’s safety or the safety of others.
Electronic Stability Program (ESP ®
)
Your vehicle is equipped with the
E lectronic Stability Program (ESP ®
). The
ESP ®
is operational as soon as the engine
is running and it monitors the vehicle’s
traction (force of adhesive friction
between the tires and the road surface) and
handling.
The ESP ®
recognizes when a wheel is
spinning or if the vehicle starts to skid.
By applying brakes to the appropriate
wheel and by limiting the engine output,
the ESP ®
works to stabilize the vehicle. The
ESP ®
is especially useful while driving off
and on wet or slippery road surfaces. The
ESP ®
also stabilizes the vehicle during
braking and steering maneuvers.
The ESP ®
warning lamp 00F2 in the
instrument cluster flashes when the ESP ®
is
engaged.
The ESP ®
warning lamp 00F2 in the
instrument cluster comes on when you
switch on the ignition. It goes out when the
engine is running.
Depending on the driving situation, the
ESP ®
R reduces the speed
R selectively brakes individual wheels
R equalizes the speed of the driven wheels
R stabilizes the vehicle when braking
R assists you in evasive maneuvers on all
roadsGWarning!
If the ESP ®
warning lamp 00F2 in the
instrument cluster flashes, proceed as
follows:
R While driving off, apply as little
throttle as possible.
R While driving, ease up on the accelerator
pedal.
R Adapt your speed and driving style to the
prevailing road conditions.
Failure to observe these guidelines could
cause the vehicle to skid.
The ESP ®
cannot prevent accidents
resulting from excessive speed.
GWarning!
The ESP ®
cannot prevent the natural laws of
physics from acting on the vehicle, nor can
it increase the traction afforded. The
ESP ®
cannot prevent accidents, including
those resulting from excessive speed in
turns, or hydroplaning. Only a safe,
attentive, and skillful driver can prevent
accidents. The capabilities of an ESP ®
equipped vehicle must never be exploited
in a reckless or dangerous manner which
could jeopardize the user’s safety or the
safety of others.
! Because the ESP ®
operates
automatically, the engine must be turned
off (ignition switched off) when the
parking brake is being tested on a brake
test dynamometer. Active braking action
through the ESP ®
may otherwise seriously

damage the brake system which is not
covered by the smart Limited Warranty.
i The ESP ®
will only function properly if
you use wheels of the recommended tire
size ( Y page 217).
Hydraulic brake assistant
The hydraulic brake assistant operates in
emergency situations. If you apply the
brakes very quickly, the hydraulic brake
assistant automatically provides full
brake boost, thereby potentially reducing
the braking distance.
XApply continuous full braking pressure
until the emergency braking situation is
over.
The ABS will prevent the wheels from
locking.
When you release the brake pedal, the
brakes function again as normal. The
hydraulic brake assistant is then
deactivated.
GWarning!
When the hydraulic brake assistant is
malfunctioning, the brake system is still
functioning normally, but without the
additional brake boost that would normally
be provided during an emergency braking
maneuver. Therefore, the braking distance
may increase.
GWarning!
The hydraulic brake assistant cannot
prevent the natural laws of physics from
acting on the vehicle, nor can it increase
braking efficiency beyond that afforded by
the condition of the vehicle brakes and
tires or the traction afforded. The
hydraulic brake assistant cannot prevent
accidents, including those resulting from
excessive speed in turns, following
another vehicle too closely, or
hydroplaning. Only a safe, attentive, and
skillful driver can prevent accidents. The
capabilities of a hydraulic brake assistant
equipped vehicle must never be exploited
in a reckless or dangerous manner which
could jeopardize the user’s safety or the
safety of others.
Activating the hazard warning flasher
after an emergency braking maneuver
If you bring the vehicle to a complete stop
by strongly braking at a speed of more than
43 mph (70 km/h), the hazard warning
flasher comes on automatically as soon as
the vehicle is at a standstill. The hazard
warning flasher will remain on until it is
switched off using the hazard warning
flasher switch ( Y page 68) or until the
speed of the vehicle has exceeded 6 mph
(10 km/h).
Anti-theft systems
Electronic immobilizer
The electronic immobilizer prevents
unauthorized persons from starting your
vehicle.
When leaving the vehicle, always take the
key with you and lock the vehicle. The
engine can be started by anyone with a key
that is left inside the vehicle.
XActivating: Remove the key from the
starter switch.XDeactivating: Insert the key in the
starter switch.XTurn the key to starter switch position 1.
Anti-theft warning system*
Once the anti-theft warning system has
been armed, a visual and audible alarm is
triggered when
R someone opens a door or the tailgate
R someone enters the vehicle’s interior

Starting the engine
! Shift the transmission into park
position P or reverse gear R only when the
vehicle is stopped in order to avoid
damaging the transmission.
XMake sure the gear selector lever is set
to park position P.
The transmission position indicator
should be on P.XDo not depress the accelerator pedal.XTurn the key to starter switch position

The engine starts automatically (“touch-
start” function).
Driving
XDepress the brake pedal.XPress release button 0046 (Y page 78) to
disengage the gear selector lever lock.XMove the gear selector lever to drive
position D.
D appears in the transmission position
indicator.XRelease the brake pedal.XCarefully depress the accelerator pedal.GWarning!
On slippery road surfaces, never downshift
in order to obtain braking action. This
could result in drive wheel slip and
reduced vehicle control. Your vehicle’s ABS
will not prevent this type of loss of control.
GWarning!
It is dangerous to shift the transmission
out of park position P or neutral position
N if the engine speed is higher than idle
speed. If your foot is not firmly on the brake
pedal, the vehicle could accelerate quickly
forward or in reverse. You could lose
control of the vehicle and hit someone or
something. Only shift into gear when the
engine is idling normally and when your
right foot is firmly on the brake pedal.
! Do not run a cold engine at high engine
speeds. Running a cold engine at high
engine speeds may shorten the service
life of the engine.
! Simultaneously depressing the
accelerator pedal and applying the
brakes reduces engine performance and
causes premature brake and drivetrain
wear.
Reversing the vehicle
! Shift the transmission into reverse
gear R only when the vehicle is stopped
in order to avoid damaging the
transmission.
You can drive in reverse gear at a speed
of up to 9 mph (15 km/h).
XDepress the brake pedal.XPress the release button ( Y page 78) to
disengage the gear selector lever lock.XMove the gear selector lever to reverse
gear R.

Parking
GWarning!
Do not park this vehicle in areas where
combustible materials such as grass, hay or
leaves can come into contact with the hot
exhaust system. These materials could be
ignited and cause a vehicle fire.
Vehicle movement can cause serious
personal injury or damage to the vehicle or
the vehicle drivetrain. Therefore, always
do the following before turning off the
engine and leaving the vehicle:

RKeep right foot on the brake pedal.
R Engage the parking brake.
R Move the gear selector lever to park
position P.
R Slowly release the brake pedal.
R When parked on an incline, always turn
the front wheels towards the curb.
R Turn the key to starter switch position 0
and remove the key from the starter
switch.
R Take the key with you and lock the vehicle
when leaving.GWarning!
With the engine not running, there is no
power assistance for the brake and
steering* systems. In this case, it is
important to keep in mind that a
considerably higher degree of effort is
necessary to brake and steer the vehicle.
Adapt your driving accordingly.
XProperly stop and park the vehicle.XDepress the brake pedal.XEngage the parking brake ( Y page 80).
When the ignition is switched on or the
engine is running, the brake warning
lamp 0027 (USA only) or 004D (Canada
only) in the instrument cluster comes on.XRelease the brake pedal.
Parking brake
The parking brake serves to secure the
vehicle against rolling away when it is
stationary or parked.
GWarning!
Engaging the parking brake while the
vehicle is in motion can cause the rear
wheels to lock up. You could lose control of
the vehicle and cause an accident. In
addition, the vehicle’s brake lights do not
light up when the parking brake is engaged.
XReleasing: Depress the brake pedal.XPull up slightly on parking brake
lever 0047 and press release button 0046.XPush parking brake lever 0047 down as far
as it will go.
When the ignition is switched on or the
engine is running, the brake warning
lamp 0027 (USA only) or 004D (Canada
only) in the instrument cluster goes out.XEngaging: Pull up parking brake
lever 0047 firmly.
When the ignition is switched on or the
engine is running, the brake warning
lamp 0027 (USA only) or 004D (Canada
only) in the instrument cluster comes on.GWarning!
Getting out of your vehicle with the
transmission not fully engaged in park
position P is dangerous. When the engine is
shut off and the brakes are released, the
vehicle can be moved freely with the gear
selector lever in all positions except park
position P. Also, when parked on an incline,
park position P alone may not prevent your
vehicle from moving, possibly hitting
people or objects.
Always engage the parking brake in
addition to shifting to park position P.
When parked on an incline, always turn the
front wheels towards the curb.
GWarning!

you, and lock the vehicle. Do not leave
children unattended in the vehicle, or with
access to an unlocked vehicle. Children
could release the parking brake and/or
move the gear selector lever from park
position P, either of which could result in
an accident and/or serious personal
injury.
Brake pedal
The brake pedal has two brake circuits
independent of each other. A brake servo is
used during braking (when the engine is
running) to increase pedal force.
GWarning!
Make sure absolutely no objects are
obstructing the pedals’ range of motion.
Keep the driver’s footwell clear of all
obstacles. If there are any floormats* or
carpets in the footwell, make sure the
pedals still have sufficient clearance.
During sudden acceleration or braking
maneuvers, the objects could get caught
between or beneath the pedals and restrict
your ability to brake or accelerate. This
could lead to accidents and/or injury.
GWarning!
Considerably more effort will be required
to apply the brakes if
Rthe brake servo has failed
Ra brake circuit has failed
Rthe engine is switched off, e.g. for
towing the vehicle
The braking distance is likewise greater.
Make sure the engine is running whenever
the vehicle is rolling. Have the brake
system repaired at an authorized smart
center, if there is a fault in the brake
system.
If a brake circuit has failed (Y page 166),
you must depress brake pedal \000F further
down to achieve the same effect and the
braking distance is increased.
iThe brake servo will only function with
the engine switched on.
GWarning!
In the event of the vehicle needing to be
towed, a significantly greater amount of
pedal pressure will be required when the
engine is switched off.
Turning off the engine
GWarning!
Do not turn off the engine before the
vehicle has come to a complete stop. With
the engine not running, there is no power
assistance for the brake and steering*
systems. In this case, it is important to
keep in mind that a considerably higher
degree of effort is necessary to brake and
steer the vehicle.

Driving systems
Cruise control*
The cruise control maintains the speed you
set for your vehicle automatically. On
downhill grades, the cruise control does
not brake the vehicle via the brake system.
The cruise control can only use the braking
power of the engine. You must apply the
brakes yourself in order to reduce the
vehicle speed. The cruise control will then
be canceled.
GWarning!
The cruise control is a convenience system
designed to assist the driver during
vehicle operation. The cruise control
cannot take road, traffic, and weather
conditions into account. The driver is and
must always remain responsible for the
vehicle’s speed and for safe brake
operation.
Do not use the cruise control
Rif the road, traffic, and weather
conditions do not make it advisable to
travel at a constant speed

Tires and wheels
Safety notes
Contact an authorized smart center for
information on tested and recommended
rims and tires for summer and winter
operation. They can also offer advice
concerning tire service and purchase.
GWarning!
Replace rims or tires with the same
designation, manufacturer and type as
shown on the original part. For further
information contact an authorized smart
center. If incorrectly sized rims and tires
are mounted, the wheel brakes or
suspension components can be damaged.
Also, the operating clearance of the wheels
and the tires may no longer be correct.
GWarning!
Worn, old tires can cause accidents. If the
tire tread is worn to minimum tread depth,
or if the tires have sustained damage,
replace them.
When replacing rims, only use genuine
smart wheel bolts specified for the
particular rim type. Failure to do so can
result in the bolts loosening and possibly
an accident.
Retreaded tires are not tested or
recommended by smart, since previous
damage cannot always be recognized on
retreads. The operating safety of the
vehicle cannot be assured when such tires
are used.GWarning!
If you feel a sudden significant vibration
or ride disturbance, or you suspect that
possible damage to your vehicle has
occurred, you should turn on the hazard
warning flashers, carefully slow down, and
drive with caution to an area which is a safe
distance from the road.
Inspect the tires and the vehicle underbody
for possible damage. If the vehicle or tires
appear unsafe, have the vehicle towed to the
nearest authorized smart center or tire
dealer for repairs.
GWarning!
Do not drive with a flat tire. A flat tire
affects the ability to steer or brake the
vehicle. You could lose control of the
vehicle. Continued driving with a flat tire
or driving at high speed with a flat tire
will cause excessive heat build-up and
possibly a fire.
Modifications to the brake system and
wheels and the use of brake dust rings are
not permissible.
Important guidelines
R Only use sets of tires and rims of the same
type and make.
R Tires must be of the correct size for the
rim.
R Break in new tires for approximately
60 miles (100 km) at moderate speeds.
R Regularly check the tires and rims for
damage. Dented or bent rims can cause
tire pressure loss and damage to the tire
beads.
