Antilock Brake System (ABS)GWarning!
Do not pump the brake pedal. Use firm,
steady brake pedal pressure instead.
Pumping the brake pedal defeats the
purpose of the ABS and significantly
reduces braking effectiveness.
The
Antilock Brake System (ABS) regulates
the brake pressure so that the wheels do not
lock during braking. This allows you to
maintain the ability to steer your vehicle.
On slippery road surfaces, the ABS will
respond even to light brake pressure.
The ABS indicator lamp in the instrument
cluster ( Y page 22) comes on when you
switch on the ignition. It goes out when the
engine is running.
Braking
At the instant one of the wheels is about to
lock up, a slight pulsation can be felt in
the brake pedal, indicating that the ABS is
regulating the brake pressure.
XKeep firm and steady pressure on the
brake pedal while experiencing the
pulsation.
Continuous, steady brake pedal pressure
yields the advantages provided by the ABS,
namely braking power and the ability to
steer the vehicle.
A pulsating brake pedal can be an
indication of hazardous road conditions
and functions as a reminder to take extra
care while driving.
Emergency brake maneuver
XKeep continuous full pressure on the
brake pedal.GWarning!
When the ABS is malfunctioning, the
hydraulic brake assistant and the ESP ®
are
also switched off.
When the ABS is malfunctioning, the wheels
may lock during hard braking, reducing
steering capability and extending the
braking distance.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
Electronic 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 0067 in the
instrument cluster flashes when the ESP ®
is
engaged.
The ESP ®

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 0067 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 202).
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

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

lamp 0027 (USA only) or 004D (Canada
only) in the instrument cluster goes out.XEngaging: Pull up parking brake
lever 0046 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!
When leaving the vehicle, always remove the
key from the starter switch, take it with
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
R the brake servo has failed
R a brake circuit has failed
R the 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.
0046Brake pedal
If a brake circuit has failed ( Y page 150),
you must depress the brake pedal further
down to achieve the same effect and the
braking distance is increased.
i The brake servo will only function with
the engine switched on.

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.
Shifting procedure
The transmission selects individual gears
automatically, depending on:
R the gear selector lever position D
( Y page 80)
R the position of the accelerator pedal
( Y page 81)
R the vehicle speed
R uphill or downhill grades
Press release button 0046 (Y page 79) to
disengage the gear selector lever lock
when moving the gear selector lever from
R P to R, N , or D
R R to P
R N to R or P
! Allow the engine to warm up under low
load use. Do not place full load on the
engine until the operating temperature
has been reached.
Shift into reverse gear R or parking
position P only when the vehicle is
stopped.
Avoid spinning of a drive wheel for an
extended period when driving off on
slippery road surfaces. Otherwise, the
drivetrain could be damaged, which is
not covered by the smart Limited
Warranty.
With manual gearshifting M selected
( Y page 82), you can use the gear selector
lever or steering wheel gearshift control
to change the gears manually.

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

Do not overinflate tires. Overinflated
tires can adversely affect handling and
ride comfort, wear unevenly, increase
stopping distance, and result in sudden
deflation (blowout) because they are more
likely to become punctured or damaged by
road debris, potholes etc.
Do not overload the tires by exceeding the
specified load limit as indicated on the
Tire and Loading Information placard on
the driver’s door B‑pillar. Overloading the
tires can overheat them, possibly causing
a blowout. Overloading the tires can also
result in handling or steering problems, or
brake failure.
Check the tire inflation pressure at least
once a month.
Check and adjust the tire inflation
pressure when the tires are cold
( Y page 115).
Checking tire inflation pressure
manually
Follow the steps below to achieve correct
tire inflation pressure:
XRemove the cap from the valve on one tire.XFirmly press a tire gauge onto the valve.XRead the tire inflation pressure on tire
gauge and check against the
recommended tire inflation pressure on
the Tire and Loading Information
placard on the driver’s door B‑pillar
( Y page 120). If necessary, add air to
achieve the recommended tire inflation
pressure.XIf you have overfilled the tire, release
tire inflation pressure by pushing the
metal stem of the valve with e.g. a tip of
a pen. Then recheck the tire inflation
pressure with the tire gauge.XInstall the valve cap.XRepeat this procedure for each tire.Tire Pressure Monitoring System
(TPMS)*
Your vehicle may be equipped with a Tire
Pressure Monitoring System (TPMS).
It monitors the tire inflation pressure in
all four tires. A warning is issued to alert
you to a decrease in pressure in one or more
of the tires.
The Tire Pressure Monitoring System
(TPMS) is equipped with a combination low
tire pressure/TPMS malfunction telltale in
the instrument cluster. Depending on how
the telltale illuminates, it indicates a low
tire pressure condition or a malfunction in
the TPMS system itself:
R If the telltale illuminates continuously,
one or more of your tires is significantly
underinflated. There is no malfunction
in the TPMS.
R If the telltale flashes for 60 seconds and
then stays illuminated, the TPMS system
itself is not operating properly.
The TPMS only functions on wheels that are
equipped with the proper electronic
sensors.
GWarning!
The TPMS does not indicate a warning for
wrongly selected inflation pressures.
Always adjust tire inflation pressure
according to the Tire and Loading
Information placard on the driver’s door
B‑pillar.
The TPMS is not able to issue a warning due
to a sudden dramatic loss of pressure (e.g.
tire blowout caused by a foreign object). In
this case bring the vehicle to a halt by
carefully applying the brakes and avoiding
abrupt steering maneuvers.
GWarning!
Each tire should be checked monthly when
cold and inflated to the inflation pressure
recommended by the vehicle manufacturer
on the Tire and Loading Information
