129 Shifting procedure
The transmission selects individual gears
automatically, depending on:
• the gear selector lever
positionD(

page 129)
• the position of the accelerator
(

page 131)
• the vehicle speed
• uphill or downhill grades
Press release button
1 (
page 128) to
disengage the gear selector lever lock when
moving the gear selector lever from
•P toR,N, orD
•R toP
•N toR orP
!
Allow 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 gearR or parking
positionP only when the vehicle is stopped.
Avoid spinning of a drive wheel for an extend

ed period when driving off on slippery road
surfaces. Otherwise, the the drivetrain could
be damaged, which is not covered by the smart
Limited Warranty.
With manual gearshiftingM selected
(

page 132), you can use the gear selector
lever or steering wheel gearshift control

to change the gears manually.

Effect
ì
Park position
Gear selector lever position when
the vehicle is parked. Place the
gear selector lever in park
positionP only when the vehicle is
stopped. The park position is not
intended to serve as a brake when
the vehicle is parked.
Rather, the driver should always
set the parking brake in addition to
placing the gear selector lever in
park positionP to secure the
vehicle.
The key can only be removed from
the starter switch with the gear
selector lever in park positionP.
With the key removed, the gear
selector lever is locked in park
positionP.

ë
Neutral position
No power is transmitted from the
engine to the drive axle. When the
brakes are released, the vehicle
can be moved freely (pushed or
towed).
Effect

has to change the gears manually.
G
Warning!
Getting out of your vehicle with the gear
selector lever not fully engaged in park
positionP 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 ex

cept park position P. Also, park
positionP alone is not intended to or
capable of preventing your vehicle from
moving, possibly hitting people or
objects.
Always set the parking brake in addition
to shifting to park positionP
(
page 125).
When parked on an incline, turn the front
wheels towards the road curb.
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, as these materials
could be ignited and cause a vehicle fire.

131 Driving tips
Accelerator position
Your driving style influences the
transmission’s shifting behavior:
Less throttle, earlier upshifting
More throttle, later upshifting
Kickdown
Use kickdown when you want maximum
acceleration.
>Press the accelerator past the point of
resistance.
Depending on the engine speed the
transmission shifts into a lower gear.
>Ease on the accelerator when you have
reached the desired speed.
The transmission shifts up again.Stopping
When you stop briefly, e.g. at traffic lights:
>Leave the transmission in gear.
>Hold the vehicle with the brake.
When you stop for a longer period with the
engine idling and/or on a hill:
>Set the parking brake.
>Move the gear selector lever to park
positionP.
Working on the vehicle
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 move the gear selector
lever from park positionP, which could
result in an accident and/or serious
personal injury.
G
Warning!
When working on the vehicle, set the
parking brake and move the gear selec

tor lever to park positionP. Otherwise
the vehicle could roll away.

>> Controls. Driving off uphill
Your vehicle has a hill start assist system.
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.>Release the brake pedal.
>Apply sufficient pressure to the accelera

tor.
!
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 within this time, the hill start as

sistance is deactivated and a warning signal
sounds.
i
The hill start assist system is inactive if
you start off with the parking brake set.
Manual gearshiftingWith manual gearshiftingM selected, system

controlled automatic gearshifting is switched
off and you need to change the gears by up

shifting or downshifting manually using the
gear selector lever or the steering wheel
gearshift control

Allow engine to warm up under low load
use. Do not place full load on the engine until
the operating temperature has been reached.

ed period when driving off on slippery road
surfaces. Otherwise, the the drivetrain could
be damaged, which is not covered by the smart

G
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 set the parking brake in addition
to shifting to park positionP.1 Model passion only.

Emergency operation (limp
home
mode)In this mode only a certain gear or a certain
gear combination can be selected. This mode
is triggered in case of transmission malfunc

tions and enables you driving to the nearest
workshop such as a smart center.
If vehicle acceleration becomes less respon

sive or sluggish or the transmission no longer
shifts, the transmission is most likely operat

ing in limp
home (emergency operation)
mode. The transmission position indicator
flashes and the ¬ symbol appears in the mul

tifunction display (

page 136).
Driving in limp
home mode:
>Move the gear selector lever to drive
positionD (

>Continue to drive.
>Have the transmission checked at an autho

rized smart center as soon as possible.
i
It is possible that a gear combination in

cluding the reverse gear can not be selected.
Keep in mind when parking, that reversing the
vehicle might be impossible.
In case of a minor transmission malfunction, it
might be possible to teach
in the transmis

sion in order to restore the normal transmis

sion mode.
i
If the attempt to teach
in the transmission
fails, you cannot continue to drive. Therefore
we strongly recommend that you have the
transmission taught
in at a qualified work

shop or at an authorized smart center.
Teaching
in the transmission system:
>Stop the vehicle in a safe location.
>Move the gear selector lever to park
positionP.
>Turn off the engine.
>Wait at least 30 seconds before restarting.
