more.
The indicator lamp on the button goes
out.
Air conditioning
The cooling function, only operational
when the engine is running, cools the
vehicle interior down to the selected
temperature. The cooling function also
dehumidifies the air in the vehicle interior,
thus preventing the windows from fogging
up. Deactivating
It is possible to deactivate the air condi-
tioning (cooling) function of the climate
control system. The air in the vehicle will
then no longer be cooled or dehumidified.
Press button

after 5 minutes if the air conditioning is
turned off

after 30 minutes if the outside temperature
is above approximately 41°F (5°C)
iCondensation may drip out from underneath
the vehicle. This is normal and not an indication
of a malfunction.
Warning!G
If you turn off the coo ling function, the inte-
rior air is not dried. The windows can fog up
more quickly. Window fogging may impair
visibility and endanger you and others.

authorized Mercedes-Benz Light Truck Center.
iHow long the system will provide heating
depends on

the coolant temperature

the battery voltage
Regardless of the temperature and air volume
set on the climate control panel, an interior
temperature is aimed at by 72°F (22°C) and the
blower runs on low speed to protect the vehicle
battery.
iThe residual heat is automatically turned off:

when the ignition is switched on

after about 30 minutes

if the coolant temperature is too low

if the battery voltage drops

258 Operation
Driving instructions

Comply with the warnings
(
page 253) and rules for off-road
driving (
page 253).

Switch off the exterior lamps as well as
the climate control.

Select gear range 2 or 1 on the auto-
matic transmission (
page 167).

Enter and leave the water only at a
shallow spot, driving at walking speed.

Drive through the water slowly and at a
constant speed.

Do not stop vehicle while immersed in
water, and do not shut off the engine.
There is a very high level of driving
resistance in water. The surface is
slippery and may not be firm, making
pulling away in water difficult and
dangerous.

Make sure that only small bow waves
are formed when driving the vehicle
through water.

Clean mud off the tire tread after
driving through water.

To dry the brakes, apply pressure to the
brake pedal several times after leaving
the water. Crossing obstacles
!Never accelerate before driving into the
water. The bow wave could force water into the
engine and auxiliary equi pment, thus damaging
them.
!Do not open any of the vehicle’s doors while
driving through water. Water could otherwise en-
ter the vehicle interior and damage the vehicle’s
electronics, as well as the interior equipment.
!Obstacles can damage the vehicle
underbody or suspension components. If possi-
ble, use the assistance of a second person out-
side the vehicle to scout the path you intend to
take and check for adeq uate ground clearance
when you cross obstacles with your vehicle. The
person assisting you outside the vehicle should
always be a safe distance away from the vehicle
and positioned so that he or she cannot get hurt
in case of any unexpected vehicle movement.
After off-road driving or crossing obstacles,
inspect vehicle for any damage, especially
vehicle underbody and suspension components.
Failure to do so can adversely affect the vehi-
cle’s future performance, including increased
chance of an accident.

302 Operation
Tires and wheels
Uniform Tire Quality Grading Standards
(U.S. vehicles)
Tire manufacturers are required to grade
tires based on three performance
factors: treadwear, traction and
temperature resistance.1 Treadwear
2 Traction
3 Temperature resistance Quality grades can be found, where
applicable, on the tire sidewall between
tread shoulder and maximum section
width. For example:
All passenger car tires must conform to
federal safety requirements in addition to
these grades.
Treadwear
The treadwear grade is
a comparative rat-
ing based on the wear rate of the tire when
tested under controlled conditions on a
specified government test course. For
example, a tire graded 150 would wear one
and one-half (1
1/2) times as well on the
government course as a tire graded 100.
The relative performance of tires depends
upon the actual condit ions of their use,
however, and may depart significantly
from the norm due to variations in driving
habits, service practices and differences in
road characteristics and climate.
iFor illustration purposes only. Actual data
on tires are specific to each vehicle and may vary
from data shown in above illustration.

Operation
Vehicle care
Rinse with clean water and thoroughly
dry with a chamois.
Do not allow cleaning agents to dry on
the finish.
Automatic car wash
You can have your car washed in an auto-
matic car wash from the start. Automatic
car washes without brushes are prefera-
ble.
To protect the filter system, switch the
climate control to air recirculation
mode (
page 183). If the vehicle is very dirty, prewash it
before running it through the automatic
car wash.
Ornamental moldings
For regular cleaning and care of
ornamental moldings, use a damp cloth.
!Do not use scouring agents on these parts.
Never apply strong force and only use a soft,
non-scratching cloth when cleaning the vehicle.
Do not attempt to wipe the surface with a dry
cloth or sponge.
Otherwise you may scratch or damage the paint.
!Do not clean your vehicle in an automatic
touchless car wash which use caustic spray.
Otherwise the caustic spray will damage the
paint or ornamental moldings.
!Make sure that the windshield wiper switch
is set to 0 (
page 58). Otherwise, e.g. the rain
sensor could activate and cause the wipers to
move unintentionally. This may lead to vehicle
damage.
Due to the width of the vehicle, fold in exterior
rear view mirrors prior to running the vehicle
through an automatic car wash to prevent
damage to the mirrors.
iAfter running the vehicle through an auto-
matic car wash, wipe any wax off of the wind-
shield (
page 319). This will prevent smears
and reduce wiping noise which can be caused by
residual wax on the windshield.
When leaving the car wash, make sure that the
mirrors are folded out. Otherwise they may
vibrate.
!Do not use chrome cleaner on ornamental
moldings. Although ornamental moldings may
have chrome appearance, they could be made of
anodized aluminum that will be damaged when
cleaned with chrome cleaner. Instead, use a
damp cloth to clean those ornamental moldings.
For very dirty ornamental moldings of which you
are sure are chrome-plated, use a chrome
cleaner. If in doubt whether an ornamental
molding is chrome-plated, contact an authorized
Mercedes-Benz Light Truck Center.
