counterclockwise to allow any excess pres‐
sure to dissipate, and then open it.3.The coolant level is correct if it lies between
the minimum and maximum marks in the
filler neck.4.If the coolant is low, slowly add coolant up to
the specified level; do not overfill.5.Turn the cap until there is an audible click.6.Have the cause of the coolant loss elimi‐

Socket for OBD Onboard
Diagnosis
There is an OBD socket on the driver's side for
checking the primary components in the vehicle
emissions.
Emissions
▷The warning lamp lights up:
Emissions are deteriorating. Have
the vehicle checked as soon as pos‐
sible.
Canadian model: warning light indi‐
cates the engine symbol.▷The warning lamp flashes under certain cir‐
cumstances:
This indicates that there is excessive misfir‐
ing in the engine.
Reduce the vehicle speed and have the sys‐
tem checked immediately; otherwise, seri‐
ous engine misfiring within a brief period can
seriously damage emission control compo‐
nents, in particular the catalytic converter.
Fuel cap
The indicator lamp lights up.
If the fuel cap is not properly tightened,
the OBD system may conclude that fuel
vapor is escaping. If the cap is then tightened,
the display should go out in a short time.
Data memory
Your vehicle records data relating to vehicle op‐
eration, faults and user settings. These data are
stored in the remote control and can be read out
with suitable devices, particularly when the ve‐
hicle is serviced. The data obtained in this way
provide valuable information for service proc‐
esses and repair or for optimizing and develop‐
ing vehicle functions further.
In addition, if you signed a service contract for
Assist, certain vehicle data can be sent directly
from the vehicle to facilitate the desired serv‐
ices.Seite 235MaintenanceMobility235

attempt in order to allow the discharged bat‐
tery to recharge.3.Let both engines run for several minutes.4.Disconnect the jumper cables in the reverse
order.
Check the battery and recharge if necessary.
Tow-starting and towing
Automatic transmission: transporting
your vehicle
Note
Your vehicle is not permitted to be towed.
Therefore, contact a service center in the event
of a breakdown.
Do not have the vehicle towed
Have your vehicle transported on a loading
platform only; otherwise, damage may occur.◀
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.◀
Use the tow fitting screwed in at the front for
maneuvering the vehicle only.
Towing other vehicles
General information Light towing vehicle
Your vehicle must not be lighter than the
vehicle being towed; otherwise, it will not be
possible to control vehicle response.◀
Attaching the tow bar/tow rope correctly
Attach the tow bar or tow rope to the tow
fitting; connecting it to other vehicle parts may
cause damage.◀▷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.
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:
▷Maneuvering capability is limited during cor‐
nering.▷The tow bar will generate lateral forces if it
is secured with an 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.◀
