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.
Turning off the engine
GWarning!
Do not turn off the engine before the
vehicle has come to a complete stop. With
the engine not running, there is no power
assistance for the brake and steering*
systems. In this case, it is important to
keep in mind that a considerably higher
degree of effort is necessary to brake and
steer the vehicle.

Transmission
Introduction
Your vehicle is equipped with a 5‑speed
automated transmission with manual or
automatic mode. For information on
driving with the transmission see also
“Starting” ( Y page 75).
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!
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

Working on the vehicle
GWarning!
When working on the vehicle, engage the
parking brake and move the gear selector
lever to park position P. Otherwise the
vehicle could roll away which could result
in an accident and/or serious personal
injury.
Driving on uphill grades
Your vehicle has a hill‑start assist system.
GWarning!
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.
XRelease the brake pedal.XApply 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
within this time, the hill‑start assist
system is deactivated and a warning
signal sounds.
i The hill‑start assist system is inactive
if you start off with the parking brake
engaged.

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.
As an added safety feature, your vehicle has
been equipped with a tire pressure
monitoring system (TPMS) that illuminates
a low tire pressure telltale when one or
more of your tires is significantly
underinflated.
Accordingly, when the low tire pressure
telltale illuminates, you should stop and
check your tires as soon as possible, and
inflate them to the proper pressure.
Driving on a significantly underinflated
tire causes the tire to overheat and can lead
to tire failure.
Underinflation also reduces fuel
efficiency and tire tread life, and may
affect the vehicle’s handling and stopping
ability. Please note that the TPMS is not a
substitute for proper tire maintenance,
and it is the driver’s responsibility to
maintain correct tire pressure, even if
underinflation has not reached the level to
trigger illumination of the TPMS low tire
pressure telltale.
Your vehicle has also been equipped with a
TPMS malfunction indicator to indicate
when the system is not operating properly.
The TPMS malfunction indicator is
combined with the low tire pressure
telltale. When the system detects a
malfunction, the telltale will flash for
approximately 1 minute and then remain
continuously illuminated.
This sequence will continue upon
subsequent vehicle start-ups as long as the
malfunction exists. When the malfunction
indicator is illuminated, the system may
not be able to detect or signal low tire
pressure as intended.
TPMS malfunctions may occur for a variety
of reasons, including the installation of
incompatible replacement or alternatetires or wheels on the vehicle that prevent
the TPMS from functioning properly. Always
check the TPMS malfunction telltale after
replacing one or more tires or wheels on
your vehicle to ensure that the replacement
or alternate tires and wheels allow the
TPMS to continue to function properly.
i If a condition causing the TPMS to
malfunction develops, it may take up to
10 minutes for the system to signal a
malfunction using the TPMS telltale
flashing and illumination sequence.
The telltale extinguishes after a few
minutes driving if the malfunction has
been corrected.
i Operating radio transmission
equipment (e.g. wireless headsets, two-
way radios) in or near the vehicle could
cause the TPMS to malfunction.
