Steering wheel adjustment  (electrical)
(optional)
To adjust the steering wheel position, turn the electronic 
key in starter switch to position 1 or 2. With the driver’s 
door open, the steering wheel can also be operated with 
the electronic key removed or in starter switch 
position 0. The switch is located on the driver’s door.
1 Steering column, lengthen or shorten column
Move the switch to the front or rear.
2 Steering column, height
Move the switch up or down.
Note:
The steering wheel adjustment can be stored together 
with the seat and exterior mirror adjustment.
See page 93 for notes on the memory function.
Wa r n i n g !
Do not adjust the steering wheel while driving. 
Adjusting the steering wheel while driving could 
cause the driver to lose the control of the vehicle.When leaving the vehicle always remove the 
electronic key from the starter switch and lock your 
vehicle.The steering wheel adjustment feature can also be 
operated with the driver’s door open. Do not leave 
children unattended in the vehicle, or with access 
to an unlocked vehicle. Unsupervised use of vehicle 
equipment may cause serious personal injury.

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.

Winter driving instructions
The most important rule for slippery or icy roads is to 
drive sensibly and to avoid abrupt acceleration, braking 
and steering maneuvers. Do not use the cruise control 
system under such conditions.
When the vehicle is in danger of skidding, move 
selector lever to position “N” or in case of manual 
transmission declutch. Try to keep the vehicle under 
control by corrective steering action.
Road salts and chemicals can adversely affect braking 
efficiency. Increased pedal force may become necessary 
to produce the normal brake effect. We therefore 
recommend depressing the brake pedal periodically 
when traveling at length on salt-strewn roads. This can 
bring road salt impaired braking efficiency back to 
normal. A prerequisite is, however, that this be done 
without endangering other drivers on the road. If the vehicle is parked after being driven on salt treated 
roads, the braking efficiency should be tested as soon as 
possible after driving is resumed while observing the 
safety rules in the previous paragraph.
Wa r n i n g !
If the vehicle becomes stuck in snow, make sure 
that snow is kept clear of the exhaust pipe and 
from around the vehicle with engine running.

and death.To assure sufficient fresh air ventilation, open a 
window slightly on the side of the vehicle not 
facing the wind.

Battery
Important!
Battery replacement information:
The maintenance-free battery is located in the engine 
compartment on the right hand side.
The service life of the battery is dependent on its 
condition of charge. The battery should always be kept 
sufficiently charged, in order to last an optimum length 
of time. Therefore, we strongly recommend that you have the 
battery charge checked frequently, and corrected if 
necessary, especially if you use the vehicle less than 
approximately 200 miles (300 km) per month, 
mostly for short distance trips, or if it is not used for 
long periods of time.
Only charge a battery with a battery charger after the 
battery has been disconnected from the vehicle’s 
electrical circuit.
Always disconnect the battery negative lead first and 
connect last.
When removing and connecting the battery, always 
make sure that all electrical consumers are off and the 
electronic key is in starter switch position 0. The 
battery, its filler caps, the vent tube and the opposite 
plug must always be securely installed when the vehicle 
is in operation.
While the engine is running the battery terminal clamps 
must not be loosened or detached, otherwise the 
generator and other electronic components would be 
damaged.
Wa r n i n g !
Failure to follow these instructions can result in 
severe injury or death.Never lean over batteries while connecting, you 
might get injured.Battery fluid contains sulfuric acid. Do not allow 
this fluid to come in contact with eyes, skin or 
clothing. In case it does, immediately flush affected 
area with water and seek medical help if necessary.A battery will also produce hydrogen gas, which is 
flammable and explosive. Keep flames or sparks 
away from battery, avoid improper connection of 
jumper cables, smoking etc.

Jump starting Important!
A discharged battery can freeze at approximately +14
°F
(–10
°C). In that case, it must be thawed out before 
jumper cables are used. Attempting to jump start a 
frozen battery can result in it exploding, causing 
personal injury. 
Jumper cable specifications:
• Minimum cable cross-section of 25 mm
2 or 
approximately 2 AWG
• Maximum length of 11.5 ft. (3.5 m).
If the battery is discharged, the engine should be started 
with jumper cables and the (12 V) battery of another 
vehicle.
Only use 12 V battery to jump start your vehicle. Jump 
starting with more powerful battery could damage the 
vehicle’s electrical systems, which will not be covered 
by the Mercedes-Benz Limited Warranty.
The battery is located in the engine compartment on the 
right hand side.
