WARNING
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. G
WARNING
Inhalation of exhaust gas is hazardous to
your health. All exhaust gas contains
carbon monoxide (CO), and inhaling it can
cause unconsciousness and lead to death.
Do not run the engine in confined areas
(such as a garage) which are not properly
ventilated. If you think that exhaust gas
fumes are entering the vehicle while
driving, have the cause determined and
corrected immediately. If you must drive
under these conditions, drive only with at
least one window fully open at all times. 78

WARNING
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. G
WARNING
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

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. G
WARNING
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.
G
WARNING
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. If a brake circuit has failed (
Y page 164),
you must depress 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. G
WARNING
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. Driving and parking
