During the brief warm-up period this delayed upshift
and increased engine noise might be perceived as a
malfunction. However, neither the engine nor
transmission are negatively affected by this mode of
operation.
The delayed upshift is effective with vehicle speeds
below 31 mph (50 km/h) at partial throttle and engine
temperatures below 95
°F (35
°C).
To avoid overrevving the engine when the selector lever
is moved to a lower gear ran ge, t he tr an s mis sion will n ot
shift to a lower gear, if the engine’s revolutions per
minute limit would be exceeded. In this case there will
be no downshift, even when the vehicle speed reaches
the engine’s rpm limit of that gear, e.g. by applying the
service brakes.
To prevent the engine from laboring at low RPM when
driving uphill gradients or with your vehicle heavily
loaded, the automatic transmission will downshift when
necessary to maintain engine RPM within the best
torque range. Gear ranges:
Upshift through 4th gear only. Suitable for
performance driving.
Upshift through 3rd gear only. Suitable for
moderately steep hills. Since the transmission
does not shift higher than 3rd gear, this gear
selection will allow use of the engine’s braking
power downhill.
Upshift through 2nd gear only. For driving in
mountainous regions or under extreme operating
conditions. This gear selection will allow use of
the engine’s braking power when descending
steep grades.
Use this position, which makes maximum use of
the engine’s braking effect, while descending
very steep or lengthy downgrades and only at
speeds below 40 mph (60 km/h).
Note:
To avoid overrevving the engine on rpm limit, the
transmission will upshift automatically to the next
higher gear as long as the vehicle is accelerating.

Electronic stability program (ESP)
The ESP enhances directional control and reduces
driving wheel spin of the vehicle under various driving
conditions.
Over/understeering of the vehicle is counteracted by
applying brakes to the appropriate wheel to create a
countervailing vehicle movement. Engine torque is also
limited. The ESP warning lamp, located in the
speedometer dial, starts to flash when ESP is in
operation. Important!
If the ESP warning lamp
v flashes:
• During take-off apply as little throttle as possible.
• While driving ease up on the accelerator.
• Adapt your speed and driving to the prevailing road
conditions.
• Do not switch off the ESP.
Caution!
If the vehicle is towed with the front axle raised (see
page 341, “Towing the vehicle”), the engine must be
shut off (electronic key in starter switch position 0 or 1).
Otherwise, the ESP will immediately be engaged and
will apply the rear wheel brakes.
Wa r n i n g !
ESP cannot prevent the natural laws of physics
from acting on the vehicle, nor can it increase the
traction afforded. The ESP cannot prevent
accidents, including those resulting from excessive
speed in turns, or aquaplaning. Only a safe,
attentive, and skillful driver can prevent accidents.
The capabilities of an ESP equipped vehicle must
never be exploited in a reckless or dangerous
manner which could jeopardize the user’s safety or
the safety of others.

ESP control switch
ESP control switch located on center console. 1 Press to switch ESP off
ESP warning lamp v in located in speedometer
dial comes on.
2 Press to switch ESP on
ESP warning lamp v in located in speedometer
dial goes out. To improve the vehicle’s traction when driving with
snow chains, or starting off in deep snow, sand or gravel,
switch off ESP by pressing the upper half (1) of the ESP
switch. The ESP warning lamp
v located in the
speedometer dial, is continuously illuminated.
With the ESP system switched off, the engine torque
reduction feature is cancelled. Therefore, the enhanced
vehicle stability offered by ESP is unavailable.
Adapt your speed and driving to the prevailing road
conditions.
A portion of the ESP system remains active, even with
the switch in the OFF position.
If one drive wheel loses traction and begins to spin, the
brake is applied until the wheel regains sufficient
traction. The traction control engages at vehicle speeds
up to approximately 24 mph (40 km / h), and switches
off at 50 mph (80 km / h).

reduction feature are unavailable.
2 This message may be displayed if the power supply was interrupted (battery disconnected or empty). Synchronize ESP, see
page 275
3 The system is temporarily unavailable. The reason could be that the self-diagnosis has not been completed. The display will clear
itself after driving a short distance at more than 12 mph (2o km/h).
4 The system is unavailable due to low voltage, e.g. battery not being charged.
5 A malfunction has been detected in the system. In case of ESP malfunction the ESP warning lamp in the instrument cluster
illuminates and the ESP switch in the center console does not
function. If in addition the ABS is malfunctioning, only partial
engine output will be available.
6 The display or the system is malfunctioning.

It is imperative that the wheel mounting bolts be
fastened to a tightening torque of 80 ft.lb. (110 Nm)
whenever wheels are mounted.
For rim and tire specifications, refer to “Technical Data”.
Rotating wheels
The wheels can be rotated according to the degree of
tire wear while retaining the same direction of travel.
Rotating, however, should be carried out as
recommended by the tire manufacturer, before the
characteristic tire wear pattern (shoulder wear on front
wheels and tread center wear on rear wheels) becomes
visible, as otherwise the driving properties deteriorate.
Notes:
Thoroughly clean the inner side of the wheels any time
you rotate the wheels or wash the vehicle underside.
The use of retread tires is not recommended. Retread
tires may adversely affect the handling characteristics
and safety of the vehicle.
Dented or bent rims can cause tire pressure loss and
damage to the tire beads. For this reason, check rims for
damage at regular intervals. The rim flanges must be
checked for wear before a tire is mounted. Remove
burrs, if any.
Check and ensure proper tire inflation pressure after
rotating the wheels. For tire inflation pressure see
inside of fuel filler flap and also page 278.
Wa r n i n g !
Worn, old tires can cause accidents. If the tire tread
is badly worn, or if the tires have sustained
damage, replace them.When replacing rims, use only genuine
Mercedes-Benz wheel bolts specified for the
particular rim type. Failure to do so can result in
the bolts loosening and possibly an accident.

12. Using the wrench, tighten the five bolts evenly,
following the sequence illustrated, until all bolts are
tight.
Observe a tightening torque of 80 ft.lb. (110 Nm). Notes:
Before storing the jack, it should be fully collapsed, with
handle folded in.
For proper storage of vehicle jack see page 321.
