Notes on using a power washer
& WARNING Risk of an accident when
using power washers with round-spray
nozzles
The water jet can cause externally invisible
damage.
Components damaged in this way may unex‐
pectedly fail.
Do not use a power washer with round-
#
spray nozzles.
Have damaged tires or chassis parts
#
replaced immediately.
To avoid damage to your vehicle, observe the fol‐
lowing when using a power washer:
The SmartKey is at a minimum distance of
R
10 ft (3 m) away from the vehicle. Otherwise
the trunk lid could open unintentionally.
Maintain a distance of at least 11.8 in
R
(30 cm) to the vehicle.
Vehicles with decorative foil: parts of your
R
vehicle are covered with a decorative foil.
Maintain a distance of at least 27.6 in
(70 cm) between the foil-covered parts of the
vehicle and the nozzle of the power washer.
Move the power washer nozzle around whilst
cleaning. The water temperature of the
power washer must not exceed 140°F
(60°C).
Observe the information on the correct dis‐
R
tance in the equipment manufacturer's oper‐
ating instructions.
Do not direct the nozzle of the power washer
R
directly at sensitive parts, e.g. tires, soft top,
wind deflector net, gaps, electrical compo‐
nents, batteries, light sources and ventilation
slits.
Washing the vehicle by hand
* NOTE Engine damage due to water
ingress
Take care not to point the water jet

Wash the vehicle with lukewarm water using
#
a soft car sponge. When doing so, do not
