WARNING Risk of accident when using
high-pressure cleaning equipment wi th
ro und-spr aynozzles
The wate r jet from a round-spr aynozzle (dirt
grinder) may cause damage totires and sus‐
pension components that is not visible.
Components damaged in this wa yma yfa il
unexpec tedly.
00BBDo not use high-pressure cleaning
equipment wi thround-spr aynozzles to
clean your vehicle.
00BBDamaged tires or suspension compo‐
nents must be replaced immediatel y.
Toavo id damage to yourvehicle, obser vethefo l‐
lowing when using a high-pressure cleaner:
RKe ep the SmartK eyat least 10ft(3 m) away
from theve hicle. Otherwise the trunk lid
could open unintentionall y.
RMaintain a distance of at least 11.8 in
(30 cm) totheve hicle.
RVe hicles with deco rative foil: parts of your
ve hicle are co vered with a decorative foil.
Maintain a dis tance of at least 27.6 in
(70 cm) between thefo il-c ove red parts of the
ve hicle and the nozzle of the high pressure
cleaner. Mo vethe high-pressure cleaner noz‐
zle around whilst cleaning.
RObser vethe information on the cor rect dis‐
ta nce in the equipment manufacturer's oper‐
ating instructions.
RDo not point the nozzle of the high-pressure
cleaner directly at sensitive parts such as
tires, the soft top, the wind deflector net,
slits, electrical component parts, batteries,
light sources and ventilation slot s.
Washing theve hicle byhand
Obser vethe legal requirements, e.g. in a number
of countries, washing byhand is only permitted
in specially designated wash ba ys.
00BBUse a mild cleaning agent, e.g. car shampoo.

Maintenance and care

Uniform Tire Quality Grading Standards: a
uniform standard tograde thequ ality of tires
with rega rd totread quality, tire traction and
te mp erature characteristics. The quality grading
assessment is made bythe manufacturer follow‐
ing specifications from theU. S. go vernment. The
qu ality grade of a tire is imprinted on the side
wa ll of the tire.
Re commended tire pressure :th ere commen‐
ded tire pressure is the tire pressure specified
fo rth e tires mounted totheve hicle at thefa c‐
to ry.
The tire and information table conta insthere c‐
ommended tire pressures for cold tires, the max‐
imum permissible load and the maximum per‐
missible vehicle speed.
The tire pressure table conta insthere commen‐
ded tire pressures for cold tires under various
operating conditions, i.e. loading and/or speed
of theve hicle.
Increased vehicle weight due tooptional
equipment: the combined weight of all standard
and optional equipment available forth eve hicle, re
ga rdless of whe ther it is actually ins talled on
th eve hicle or not.
Rim: the part of the wheel on which the tire is
ins talled.
GA WR (Gross Axle Weight Rating): the GAWR
is the maximum permissible axle load. The
actual load on an axle must ne verexc eed the
gros s axle weight rating. The gross axle
weight
ra ti

ng can be found on theve hicle identification
plate on the B‑pillar on the driver's side.
Speed rating: the speed rating is pa rtof the tire
identification. It specifies the speed range for
which a tire is appr oved.
GV W (Gross Vehicle Weight): the gross vehicle
we ight comprises thewe ight of theve hicle
including fuel, tools, the spare wheel, accesso‐
ri es ins talled, occupants, luggage and the trailer
dr aw bar nose weight, if applicable. The gross
ve hicle weight must not exceed the gross vehicle
we ight rating GVWR as specified on theve hicle
identification plate on the B‑pillar on the driver's
side.
GV WR (Gross Vehicle Weight Rating): the
GV WR is the maximum permitted gross weight of
the fully laden vehicle (weight of theve hicle
including all accessories, occupants, fuel, lug‐
ga ge and the trailer dr awbar nose weight if appli‐
cable). The grossve hicle weight rating is speci‐
fi ed on theve hicle identification plate on the
B‑pillar on the driver's side.
Maximum weight of the laden vehicle: the
maximum weight is the sum of the curb weight
of theve hicle, thewe ight of the accessori es,the
maximum load and thewe ight of optional equip‐
ment ins talled at thefa ctor y.
Kilopascal (kPa): metric unitfor tire pressure .
6.9 kPa cor responds to1 psi. Ano ther unit for
tire pressure is bar.
10 0 ki
lopascal (kPa) equals
1 bar.
Load index: in additiontothe load-bearing
index, the load index may also be imprinted on
th e side wall of the tire. This specifies the load-
bearing capacity of the tire more precisel y.
Curb weight: thewe ight of a vehicle with stand‐
ard equipment including the maximum capacity
of fuel, oil and coolant. It also includes the air
conditioning sy stem and optional equipment if
