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

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
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. 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

WARNING
The hill-start assist system is not
designed to function as a parking brake and
does not prevent the vehicle from moving
when parked on an incline.
Always engage the parking brake in
addition to shifting to park position P.
On uphill grades the hill‑start assist
system maintains the pressure in the brake
system for approximately one second after
you have released the brake pedal.
Therefore, you can start off smoothly
without the vehicle moving immediately
after releasing the brake pedal.
X Release the brake pedal.
X Apply sufficient pressure to the
accelerator pedal.
! After approximately one second, the
hill‑start assist system stops braking
the vehicle, which then can roll
backwards. If you open the driver’s door
