CONTROLSElectronically unlock the trans-
mission lock to maneuver vehi-
cle from a danger area.
Unlocking is possible, if the
starter can spin the engine.
Before unlocking the transmis-
sion lock, set the parking brake
to prevent the vehicle from roll-
ing away.
1Press and hold down brake
pedal.
2 Press the Start/Stop button.
The starter must audibly
start. Hold the Start/Stop but-
ton pressed.
3 With your free hand, press
the button on the selector
lever, arrow 1, and press the
selector lever into selector
lever position N and hold,
arrow N, until selector lever position N is displayed in the
instrument cluster.
A vehicle messag
e is displayed.
4Release Start/Stop button
and selector lever.
5 Release brake, as soon as
the starter stops.
6 Maneuver the vehicle from
the danger area and secure it
against moving on its own.
For additional information, see
the chapter on tow-starting and
towing, refer to page 326.
Launch Control enables opti-
mum acceleration on surfaces
with good traction under dry sur-
rounding conditions.
The use of Launch Control
causes premature component
wear since this function rep-
resents a very heavy load for
the vehicle.

Do not steer the steering wheel
when driving off with Launch
Control.
Launch Control is available
when the engine is at operating
temperature. The engine is at
operating temperature after an
uninterrupted trip of at least 6
miles/10 km.
1Switch on drive-ready state.
2 Press the sport button.
SPORT will be dis played on the
instrument cluster, indicating sport
mode has been selected.
3 Press the button.
TRACTION will be displayed on the
instrument cluster and the VSC
OFF indicator la mp will illuminate.
4Select the D selector lever
position.
5 Firmly depress the brake
pedal with your left foot.
6 Fully depress and hold the
accelerator pedal at the kick-
down position.
A flag symbol will be shown in the
instrument cluster.
7The engine speed will be
adjusted for launching. Release the brake pedal
within 3 seconds.
After Launch Control has been
used, the transmission must
cool down for approx. 5 minutes
before Launch Control can be
used again. Launch Control
adjusts to the surrounding con-
ditions, when used again.
To increase vehicle stability,
activate VSC Vehicle Stability
Control System again as soon
as possible.
An experienced driver may be
able to achieve better accelera-
tion values in VSC OFF mode.
The Sport mode button influ-
ences the driving dynamics
properties of the vehicle.
The following systems are
affected, for instance:
 Engine characteristics.
 Automatic transmission.

This system supports driving off
on uphill grades.
1Hold the vehicle in place with
the foot brake.
2 Release the foot brake and
drive off without delay.
After the foot brake is released,
the vehicle is held in place for
approx. 2 seconds.
Depending on the vehicle load-
ing, the vehicle may roll back
slightly.
Within the physical limits, the
system helps to keep the vehicle
on a steady course by reducing
engine speed and by braking
the individual wheels.
VSC detects the following unsta-
ble driving conditions, for
instance:
 Fishtailing, which can lead to
oversteering. 
Loss of traction of the front
wheels, which can lead to
understeering.

WARNING
The system cannot serve as a
substitute for the driver’s personal
judgment in assessing the traffic
situation. Based on the limits of
the system, it cannot inde-
pendently react to all traffic situa-
tions. There is a risk of accident.
Adjust driving style to traffic condi-
tions. Watch the surrounding traf-
fic situation closely, be ready to
take over steering and braking at
any time, and actively intervene
where appropriate.
WARNING
When driving with a roof load, for
instance with roof-mounted lug-
gage rack, the vehicle's center of
gravity is higher, which increases
the risk of the vehicle tipping in
critical driving sit uations. There is
a risk of accidents or risk of dam-
age to property. Do not deactivate
VSC Vehicle Stability Control Sys-
tem when driving with roof load.

2023-1. CONTROLS
In this case, even if the VSC oper-
ates, it cannot operate sufficiently
to avoid a possible dangerous situ-
ation. The driver is solely responsi-
ble for understanding their
surroundings and driving at a safe
speed.
Traction mode is a version of the
VSC Vehicle Stability Control
System where forward momen-
tum is optimized.
The system ensures maximum
headway on special road condi-
tions or loose road surfaces, for
instance unplowed snowy
roads, but with somewhat lim-
ited driving stability.
When Traction mode is acti-
vated, the vehicle has maximum
traction. Driving stability is lim-
ited during acceleration and
when driving in curves.
You may find it useful to briefly
activate Traction mode in the
following situations:
 When driving in slush or on
uncleared, snow-covered
roads.
 When driving off from deep
snow or loose ground.
 When driving with snow chains.
If Traction mode is activated,

power transfer in all driving con-
ditions by helping prevent wheel
spin at either rear wheel.

Moving parts need to begin
working together smoothly.
The following instructions will
help you to achieve a long vehi-
cle life and good efficiency.
During break-in, do not use the
Launch Control, refer to page
135.Do not exceed the maximum
engine and road speed:

For gasoline engine 4,500
rpm and 100 mph/160 km/h.
Avoid full load or kickdown
under all circumstances.
The engine and vehicle speed
can gradually be increased.
Tire traction is not optimal due to
manufacturing circumstances
when tires are brand-new; they
achieve their full traction poten-
tial after a break-in time.
Drive conservatively for the first
200 miles/300 km.

Temperature A B C
All passenger vehicle tires must
conform to Federal Safety
Requirements in addition to
these grades
The treadwear grade is a com-
parative rating based on the
wear rate of the tire when tested
under controlled conditions on a
specified government test
course. E.g., a tire graded 150
would wear one and one-half, 1
g, times as well on the govern-
ment course as a tire graded
100. The relative performance
of tires depends upon the actual
conditions of their use, however,
and may depart significantly
from the norm due to variations
in driving habits, service prac-
tices and differences in road
characteristics and climate.
The traction grades, from high-
est to lowest, are AA, A, B, and
C.Those grades represent the
tire's ability to stop on wet pave-
ment as measured under con-
trolled conditions on specified
government test surfaces of
asphalt and concrete. A tire
marked C may have poor trac-
tion performance.
The traction grade assigned to
this tire is based on
straight-ahead braking traction
tests, and does not include
acceleration, cornering, hydro-
planing, or peak traction charac-
teristics.
The temperature grades are A,
the highest, B, and C, represent-
ing the tire's resistance to the
generation of heat and its ability
to dissipate heat when tested
under controlled conditions on a
specified indoor laboratory test
wheel. Sustained high tempera-
ture can cause the material of
the tire to degenerate and
reduce tire life, and excessive
temperature can lead to sudden
tire failure.
The grade C corresponds to a
level of performance which all
passenger vehicle tires must
meet under the Federal Motor
Vehicle Safety Standard No.
109. Grades Band A represent
higher levels of performance on
the laboratory test wheel than
the minimum required by law.
