do not replace a defective fuse with a substitute
of another color or amperage rating; this could
lead to a circuit overload, ultimately resulting in
a fire in the vehicle.◀
A pair of plastic tweezers is found on the current
distributor.
See the inside of the cover for information on
fuse assignment.

Manual transmission
Gearshift lever in neutral position.
7-gear Sport automatic transmission Manually release the transmission lock
Manually release the transmission lock,
even if there is no malfunction involving the
transmission. Otherwise, there is the danger
that the transmission lock will be engaged au‐
tomatically during towing.◀
Manually release the transmission lock, refer to
page 58.
Adhere to the towing speed and distance
Do not exceed a towing speed of 30 mph/
50 km/h and a towing distance of 30 miles/50 km
or damage to the transmission can occur.◀
Observe during towing Observe the notes on towing
Observe all notes on towing or vehicle
damage or accidents can occur.◀▷Make sure that the ignition is switched on;
otherwise, the low beams, tail lamps, turn
signals, and windshield wipers may be un‐
available.▷When the engine is stopped, there is no
power assist. Consequently, more force
needs to be applied when braking and steer‐
ing.▷Larger steering wheel movements are re‐
quired.▷Switch on the hazard warning system, de‐
pending on local regulations.▷If the electrical system has failed, clearly
identify the vehicle being towed by placing
a sign or a warning triangle in the rear win‐
dow.▷Do not tow the vehicle with the rear axle
tilted, as the front wheels could turn.Towing methods
Do not lift the vehicle
Do not lift the vehicle by the tow fitting or
body and chassis parts; otherwise, damage may
result.◀
Tow bar
The tow fittings used should be on the same
side on both vehicles.
Should it prove impossible to avoid mounting
the tow bar at an offset angle, please observe
the following:▷Clearance and maneuvering capability will
be sharply limited during cornering.▷The tow bar will generate lateral forces if it
is attached offset.
Tow rope
When starting to tow the vehicle, make sure that
the tow rope is taut.
To avoid jerking and the associated stresses on
the vehicle components when towing, always
use nylon ropes or nylon straps.
Attaching the tow rope correctly
Only secure the tow rope on the tow fit‐
ting; otherwise, damage can occur when it is se‐
cured on other parts of the vehicle.◀
Tow truck Do not lift the vehicle
Do not lift the vehicle by the tow fitting or
body and chassis parts; otherwise, damage may
result.◀
Secure the vehicle against rolling off
Apply the parking brake after towing and
secure the vehicle against rolling off if neces‐
sary.
Have the operability of transmission position P
checked by the service center.◀

Caring for special components
Light-alloy wheels
Use wheel cleaner, particularly during the winter
months. Do not use aggressive, acidic, strongly
alkaline or abrasive cleaners, or steam jets
above 140 ℉/60 ℃; follow the manufacturer's
instructions.
Chrome surfaces
Carefully clean components such as the radiator
grille or door handles with an ample supply of
water, possibly with shampoo added, particu‐
larly when they have been exposed to road salt.
Rubber components
Aside from water, treat only with rubber cleans‐
ers.
When cleaning rubber seals, do not use any sil‐
icon-containing car care products in order to
avoid damage or reduced noise damping.
Fine wood parts
Clean fine wood facing and fine wood compo‐
nents only with a moist rag. Then dry with a soft
cloth.
Plastic components
These include:▷Imitation leather surfaces.▷Headliner.▷Lamp lenses.▷Instrument cluster cover.▷Matte black spray-coated components.▷Painted parts in the interior.
Clean with a microfiber cloth.
Moisten the cloth lightly with water if necessary.
Do not soak the headliner.
Do not use cleansers that contain alcohol
or solvents
Do not use cleansers that contain alcohol or sol‐
vents, such as lacquer thinners, heavy-duty
grease removers, fuel, or such; this could lead to
surface damage.◀
Safety belts
Dirty belt straps impede the reeling action and
thus have a negative impact on safety.
No chemical cleaning
Do not clean chemically; this can destroy
the webbing.◀
Use only a mild soapy solution, with the safety
belts clipped into their buckles.
Do not allow the reels to retract the safety belts
until they are dry.
Carpets and floor mats No objects in the area around the pedals
Keep floor mats, carpets, and any other
objects out of the area of motion of the pedals;
otherwise, the function of the pedals could be
impeded while driving
Do not place additional floor mats over existing
mats or other objects.
Only use floor mats that have been approved for
the vehicle and can be properly fixed in place.
Ensure that the floor mats are securely fastened
again when they are returned after being re‐
moved, such as for cleaning.◀
Floor mats can be removed from the passenger
compartment for cleaning.
When returning the floor mats, secure them
again to prevent slipping.
If the floor carpets are very dirty, clean with a
microfiber cloth and water or a textile cleaner. To
prevent matting of the carpet, rub back and forth
in the direction of travel only.
Cleaning the interior
When cleaning the interior, do not move
both seats all the way forward while moving
them to their uppermost position and leaning
the backrests forward. Otherwise, the seatsSeite 184MobilityCare184
