temporary breathing difficulty for people
with asthma or other breathing trouble. To
avoid this, you may wish to get out of the
vehicle as soon as it is safe to do so. If you
have any breathing difficulty but cannot
get out of the vehicle after the air bag
inflates, then get fresh air by opening a
window or door.GWarning!
To reduce the risk of injury when the front
air bags inflate, it is very important for
the driver and passenger to always be in a
properly seated position and to wear their
respective seat belt.
For maximum protection in the event of a
collision always be in normal seated
position with your back against the
backrest. Fasten your seat belt and ensure
it is properly positioned on your body.
Since the air bag inflates with
considerable speed and force, a proper
seating and hands on steering wheel
position will help to keep you at a safe
distance from the air bag.
Occupants who are unbelted, out of position
or too close to the air bag can be seriously
injured or killed by an air bag as it
inflates extremely quickly and with great
force:
R Sit properly belted in a position that is
as upright as possible with your back
against the seat backrest.
R Adjust the driver’s seat as far as possible
rearward, still permitting proper
operation of vehicle controls. The
distance from the center of the driver’s
breastbone to the center of the air bag
cover on the steering wheel must be at
least 10 inches (25 cm) or more. You should
be able to accomplish this by
adjustments to the seat. If you have any
problems, please contact an authorized
smart center.
R Do not lean your head or chest close to the
steering wheel or dashboard.
R Keep hands on the outside of the steering
wheel rim. Placing hands and arms inside
the rim can increase the risk and
potential severity of hand/arm injury
when the driver’s front air bag inflates.
R Adjust the passenger seat as far as
possible rearward from the dashboard
when the seat is occupied.
R Occupants, especially children, should
never place their bodies or lean their
heads in the area of the door where the
head-thorax air bag (cabriolet) or
thorax-pelvis side air bag (coupé)
inflates. This could result in serious
injuries or death should the head-thorax
air bag (cabriolet) or thorax-pelvis side
air bag (coupé) be deployed. Always sit
as upright as possible, wear the seat belt
properly and use an appropriately sized
infant restraint, toddler restraint, or
booster seat recommended for the size
and weight of the child.
Failure to follow these instructions can
result in severe injuries to you or other
occupants.
If you sell your vehicle, it is important that
you make the buyer aware of this safety
information. Be sure to give the buyer this
Operator’s Manual.
i Air bags are designed to deploy only in
certain frontal impacts (front air bags
and knee bags), or side impacts (head-
thorax air bags, window curtain air bags
and thorax-pelvis air bags) which
exceed preset thresholds. Only during
these events will they provide their
supplemental protection.
The driver and passenger should always
wear their seat belts. Otherwise it is not
possible for air bags to provide their
supplemental protection.
In case of other types of impacts and
impacts below air bag deployment
thresholds, air bags will not deploy. The
driver and passenger will then be
protected to the extent possible by a34Occupant safety>> Safety.

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

indicates that the respective systems
are operational.
Seats
Safety notes
GWarning!
All seat adjustments, as well as fastening
of seat belts, must be done before the
vehicle is operated.
GWarning!
When adjusting the seat, make sure no one
becomes trapped.
Do not adjust the driver’s seat while
driving. Adjusting the seat while driving
could cause the driver to lose control of the
vehicle.
Never ride in a moving vehicle with the seat
backrest in an excessively reclined
position as this can be dangerous. You
could slide under the seat belt in a
collision. If you slide under the seat belt,
it could apply force at the abdomen or neck,
potentially causing serious or fatal
injuries. The seat backrest and seat belts
provide the best restraint when the wearer
is in a position that is as upright as
possible and seat belts are properly
positioned on the body.
Your seat must be adjusted so that you can
correctly fasten your seat belt.
Observe the following points:
R Adjust the seat backrest until your arms
are slightly angled when holding the
steering wheel.
R Adjust the seat to a comfortable seating
position that still allows you to reach the
accelerator/brake pedal safely. The
position should be as far back as
possible with the driver still able to
operate the controls properly.
R Never place hands under the seat or near
any moving parts while a seat is being
adjusted.
Failure to do so could result in an accident
and/or serious personal injury.
Observe the notes on the air bag system.
GWarning!
Children 12 years old and under must be
seated and properly secured in an
appropriately sized infant restraint,
toddler restraint, or booster seat
recommended for the size and weight of the

The brake fluid level is correct when it
is between the minimum mark and the
maximum mark.
R If the brake fluid level has fallen
slightly below the minimum mark,
drive to an authorized smart center.
R If the brake fluid level has fallen
significantly below the minimum
mark, call Roadside Assistance or an
authorized smart center.XRemount the service flap and close it
( Y page 122).
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.

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 127).
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 132). 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
P ressure 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
placard. If your vehicle has tires of a
different size than the size indicated on
the Tire and Loading Information placard,
you should determine the proper tire
inflation pressure for those tires.

Always follow the recommended tire
inflation pressure ( Y page 127) for proper
tire inflation.
Loading the vehicle
Two labels on your vehicle show how much
weight it may properly carry.
1)The Tire and Loading Information
placard can be found on the driver’s
door B‑pillar. This placard tells you
important information about the
number of people that can be in the
vehicle and the total weight that can be
carried in the vehicle. It also contains
information on the proper size and
recommended tire inflation pressures
for the original equipment tires on
your vehicle.2)The certification label, also found on
the driver’s door B‑pillar, tells you
about the gross weight capacity of your
vehicle, called the Gross Vehicle
Weight Rating (GVWR). The GVWR
includes the weight of the vehicle, all
occupants, fuel and cargo. The
certification label also tells you about
the front and rear axle weight capacity,
called the Gross Axle Weight Rating
(GAWR). The GAWR is the total allowable
weight that can be carried by a single
axle (front or rear). Never exceed the
GVWR or GAWR for either the front axle
or rear axle.0046 Driver’s door B‑pillarFollowing is a discussion on how to work
with the information contained on the Tire
and Loading Information placard with
regards to loading your vehicle.
Tire and Loading InformationGWarning!
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.
Tire and Loading Information placard
i Data shown on Tire and Loading
Information placard example are for
illustration purposes only. Load limit
data are specific to each vehicle and may
vary from data shown in the following
illustration. Refer to Tire and Loading
Information placard on vehicle for
actual data specific to your vehicle.
The Tire and Loading Information placard
showing load limit information 0046 is
located on the driver’s door B‑pillar
( Y page 132).
XLocate the statement “The combined
weight of occupants and cargo should
never exceed XXXX kg or XXXX lbs.” on the
Tire and Loading Information placard.132Tires and wheels>> Operation.

Steps for determining correct load limit
The following steps have been developed as required of all manufacturers under Title 49,
Code of U.S. Federal Regulations, Part 575 pursuant to the “National Traffic and Motor
Vehicle Safety Act of 1966”.XStep 1: Locate the statement “The combined weight of occupants and cargo should never
exceed XXXX kg or XXXX lbs.” on your vehicle’s Tire and Loading Information placard.XStep 2: Determine the combined weight of the driver and passenger that will be riding
in your vehicle.XStep 3: Subtract the combined weight of the driver and passenger from XXXX kilograms
or XXXX lbs.XStep 4: The resulting figure equals the available amount of cargo and luggage load
capacity. For example, if the “XXXX” amount equals 540 lbs and there will be one 150 lbs
passenger in your vehicle, the amount of available cargo and luggage load capacity is
390 lbs (540 lbs - 150 lbs = 390 lbs).XStep 5: Determine the combined weight of luggage and cargo being loaded on the
vehicle. That weight may not safely exceed the available cargo and luggage load
capacity calculated in step 4.
i The maximum cargo compartment load is 110 lbs (50 kg).
The following table shows examples on how to calculate total and cargo load capacities
with varying seating configurations and number and size of occupants. The following
examples use a load limit of 540 lbs. This is for illustration purposes only . Make sure
you are using the actual load limit for your vehicle stated on the vehicle’s Tire and
Loading Information placard ( Y page 132).

sudden tire failure. The grade C
corresponds to a level of performance
which all passenger car tires must meet
under the Federal Motor Vehicle Safety
Standard No. 109. Grades B and A represent
higher levels of performance on the
laboratory test wheel than the minimum
required by law.
Rotating tires
GWarning!
Do not rotate front and rear wheels as they
have different dimensions, e.g. rim size,
wheel offset etc. Otherwise, the handling
can be affected and you could endanger
yourself and others.
Thoroughly clean the mounting face of the
wheels and brake discs, i.e. the inner side
of the wheels/tires each time the wheels/
tires are changed. Check for and ensure
proper tire inflation pressure.
GWarning!
Have the tightening torque checked after
changing a wheel. Wheels could become
loose if not tightened with a torque of
81 lb‑ft (110 Nm).
Only use genuine smart wheel bolts
specified for your vehicle’s rims.
For information on wheel change, see “Flat
tire” ( Y page 188).
