R Do not start the engine if the battery is frozen. Let the battery thaw first.
R Only jump-start from batteries with a 12 V voltage rating.
R Only use jump leads that are not damaged and have a sufficient cross-section and insulated
terminal clamps.
R Make sure that the two vehicles do not touch.
Make sure that:
R the jumper cables are not damaged.
R when the jumper cables are connected to the battery, uninsulated sections of the terminal

!Make sure that the electric parking brake
is released. If the electric parking brake is
faulty, visit a qualified specialist workshop.
!Only secure the tow rope or tow bar at the
towing eyes. Otherwise, the vehicle could
be damaged.
!Do not use the towing eyes for recovery
purposes as this could damage the vehicle. If in doubt, recover the vehicle with a crane.
!When towing, pull away slowly and
smoothly. If the tractive power is too high,
the vehicles could be damaged.
!The vehicle can be towed a maximum of
30 miles (50km). The towing speed of
30 mph (50km/h) must not be exceeded.
If the vehicle has to be towed more than
30 miles (50km), the front axle must be
raised or the entire vehicle raised andtransported.
!Do not tow with sling-type equipment.
This could damage the vehicle.
!When towing vehicles with KEYLESS-GO,
use the key instead of the Start/Stop but-
ton. Otherwise, the automatic transmission
may shift to position Pwhen the driver's or
front-passenger door are opened, which
could lead to damage to the transmission.
!Vehicles with automatic transmission
must not be started by tow-starting. This
could otherwise damage the transmission.
It is better to have the vehicle transported
than to have it towed away.
If the vehicle can no longer be driven because of an accident or breakdown, you have the
following options:
R transporting the vehicle
As a rule, you should have the vehicle trans-
ported.

applied in certain circumstances, or
R the transmission may not be shifted to P
iSwitch off non-essential consumers, e.g.
