2008 MERCEDES-BENZ GLK SUV brake light

R
Select shift range 1.
R Drive very slowly.
R As far as possible, try to drive straight over
the centre of obstacles, front wheel first,
then rear wheel.
! Obstacles could damage the floor of the
vehicle or components of the chassis. Ask
passengers for guidance when driving over
large obstacles. Any damage to the vehicle
always increases the risk of an accident. Fording
Water depth
:must not exceed 30 cm when
the vehicle is loaded and ready to drive.
Loaded and ready to drive means: a full tank,
all fluids topped up and the driver is in the
vehicle.
! The depth of water must not exceed
30 cm. Note that the possible water depth
is less in flowing water.
R Establish how deep the water is and the
characteristics of the body of water before
fording.
R Restrict the shift range to 1or 2.
R Avoid high engine speeds.
R Enter and exit the water at a flat place and
at a steady walking pace.
! Under no circumstances should you
accelerate before entering the water. The
bow wave could cause water to enter and damage the engine and neighbouring
assemblies.
R Drive slowly and at an even speed through
the water.
R Do not stop.
! Do not open any of the vehicle’s doors
while fording. Otherwise, water could get
into the vehicle interior and damage the
vehicle’s electronics and interior equip-
ment.
R Water offers a high degree of resistance,
and the ground is slippery and in some
cases unstable. Therefore, it is difficult and
dangerous to pull away in the water.
R Ensure that a bow wave does not form as
you drive.
R Clean any mud from the tyre tread after
crossing a ford.
R Apply the brakes to dry them after crossing
a ford. Driving on sand
Observe the following rules when driving on
sand:
R Select a shift range appropriate to the ter-
rain.
R Drive quickly to overcome the rolling resist-
ance. The vehicle could otherwise dig itself
into the sand.
R Drive in the tracks of other vehicles, if pos-
sible. Make sure that the ruts are not too
deep, that the sand is firm enough and that
your vehicle has sufficient ground clear-
ance. Off-road driving

removed, remove the ball coupling and clean
it.
If the ball coupling can still not be fitted
(locked) after it has been cleaned, remove the
ball coupling. The trailer coupling must then
not be used to tow a trailer, as safe operation
is not guaranteed.
Have the entire trailer coupling checked at a
qualified specialist workshop. Mercedes-
Benz recommends that you use a Mercedes-
Benz Service Centre for this purpose. In par-
ticular, work relevant to safety or on safety-
related systems must be carried out at a quali-
fied specialist workshop. Notes on towing a trailer
G
Risk of accident
When reversing the vehicle towards the
trailer, make sure there is nobody between
the trailer and the vehicle.
Couple and uncouple the trailer carefully. If
you do not couple the trailer to the towing
vehicle correctly, the trailer could become
detached.
Make sure that the following values are not
exceeded:
R the permissible trailer drawbar noseweight
R the permissible trailer load
R the permissible rear axle load of the towing
vehicle
R the maximum permissible gross vehicle
weight of both the towing vehicle and the
trailer
You will find the applicable permissible val-
ues, which must not be exceeded, in the vehi-
cle documents.
You will find the values approved by the man-
ufacturer on the vehicle identification plates
and those for the towing vehicle in the "Tech-
nical data" section. You will find installation dimensions and loads
in the "Technical data" section
(Y page 253).
The maximum drawbar load of the trailer
drawbar on the ball coupling is 80 kg. How-
ever, the actual noseweight must not exceed
the value given on the trailer coupling and
trailer identification plates. The lowest weight
applies.
! Use a noseweight as close as possible to
the maximum permissible noseweight. Do
not use a noseweight of less than 50 kg,
otherwise the trailer may come loose.
Bear in mind that the payload and the rear
axle load are reduced by the actual nose-
weight.
i The height of the ball coupling changes
with the load of the vehicle. If necessary,
use a trailer with a height-adjustable trailer
drawbar.
Coupling up a trailer G
Risk of injury
Do not disconnect a trailer with an engaged
overrun brake. Otherwise, your hand could
become trapped between the bumper and
trailer drawbar.
! Do not disconnect a trailer with an
engaged overrun brake. Otherwise, your
vehicle could be damaged by the rebound-
ing of the overrun brake.
X Position the trailer level behind the vehicle.
X Couple up the trailer.
X Establish the electrical connection
between the vehicle and the trailer.
Driving tips i
Observe the notes on ESP ®
trailer stabi-
lisation (Y page 53).
In Germany, the maximum permitted speed
for vehicle/trailer combinations is 80 km/h. 164

G
Risk of accident
A maximum speed of 80 km/h should not be
exceeded, even in countries where higher
speeds are permitted for vehicle/trailer com-
binations. This lowers the risk of an accident.
When towing a trailer, your vehicle's handling
characteristics will be different in comparison
to when driving without a trailer.
The vehicle/trailer combination:
R is heavier
R is restricted in its acceleration and gradi-
ent-climbing capability
R has an increased braking distance
R is affected more by strong crosswinds
R demands more sensitive steering
R consumes more fuel
On long and steep downhill gradients, you
must select shift range 1,2or 3in good time.
i This also applies if you have activated
cruise control* or Speedtronic*.
This will use the braking effect of the engine,
so less braking will be required to maintain
the speed. This relieves the load on the brake
system and prevents the brakes from over-
heating and wearing too quickly. If you need
additional braking, depress the brake pedal
repeatedly rather than continuously. G
Risk of accident
Never depress the brake pedal continuously
while the vehicle is in motion, e.g. never cause
the brakes to rub by applying constant slight
pedal pressure. This causes the brake system
to overheat, increases the braking distance
and can lead to the brakes failing completely. Driving tips
R
Maintain a greater distance from the vehi-
cle in front than when driving without a
trailer.
R Avoid braking abruptly. If possible, brake
gently at first to allow the trailer to run on.
Then, increase the braking force rapidly.
R The values given for gradient-climbing
capabilities from a standstill refer to sea
level. When driving in mountainous areas,
note that the power output of the engine,
and consequently the vehicle's gradient-
climbing capability, decrease with increas-
ing altitude.
If the trailer swings from side to side:
X Do not accelerate.
X Do not counter-steer.
X Brake if necessary. G
Risk of accident
On no account should you attempt to draw the
vehicle/trailer combination out by increasing
speed. Removing the ball coupling
X Pull the protective cap off the lock in the
handwheel.
X Insert the key into the lock in the hand-
wheel.
X Turn the key clockwise.
The lock is unlocked.
X Hold the ball coupling. Pull the handwheel
away from the ball coupling and turn it
clockwise until it engages.
The green area on the ball coupling is
aligned with the red mark on the hand-
wheel.
X Pull out the ball coupling downwards.
X Clean the ball coupling if it is dirty.
X Open the stowage well under the luggage
compartment floor. Trailer towing*

coupling recess.
X Press the protective cap into the ball cou-
pling recess until it engages.
X Store the ball coupling with the key inser-
ted in the ball coupling recess.
X Fold the trailer power socket upwards. G
Risk of accident
Do not carry the ball coupling in the vehicle
interior if it is not secured.
Otherwise, you and others could be injured by
the ball coupling being thrown around if you:
R brake sharply
R change direction suddenly
R are involved in an accident Trailer power supply
When it leaves the factory, your vehicle's
trailer socket outlet is equipped with a per-
manent power supply and a power supply that
is switched on via the ignition lock.
The permanent power supply is supplied via
trailer socket pin 9.
The power supply that is switched on via the
ignition lock is supplied via trailer socket pin
10.
! You can connect consumers with a power
rating of up to 240 W to the permanent
power supply and up to 180 W to the power
supply that is switched on via the ignition
lock.
You must not charge a trailer battery using
the power supply.
The trailer's permanent power supply is
switched off in the event of low vehicle supply
voltage and after six hours at the latest.
The trailer's turn signal lamps are only guar-
anteed to function when bulbs are used.
You can obtain further information about
installing the trailer electrics from a qualified
specialist workshop, e.g. a Mercedes-Benz
Service Centre. X
To switch the connected power supply
on or off: turn the key in the ignition lock
to position 2or 0, respectively. Trailer with 7-pin connector
If your trailer has a 7-pin connector, you can
connect it to the 13-pin socket on the ball
coupling using an adapter or, if necessary, an
adapter cable. Both of these can be obtained
at a qualified specialist workshop, e.g. at a
Mercedes-Benz Service Centre.
Fitting the adapter X
Open the socket cover.
X Insert connector with lug :into
groove ;on the socket and turn the con-
nector clockwise to the stop.
X Make the cover engage.
X If you are using an adapter cable, secure
the cable to the trailer with cable ties.
! Make sure that there is sufficient cable
play so that the cable cannot become
detached when cornering. 166

Otherwise, you could damage the paint fin-
ish or plastic. H
Environmental note
Dispose of empty packaging, cleaning cloths
and polishing wads in an environmentally
responsible manner. Vehicle care
! Do not park the vehicle for a long period
of time directly after cleaning, especially if
the wheels have just been cleaned with a
wheel cleaner. Wheel cleaners could cause
rapid corrosion of the brake discs and
brake pads/linings. After cleaning, park
the vehicle when it is at normal operating
temperature.
Automatic car wash You can wash the vehicle in an automatic car
wash from the beginning.
! Do not use a touch-free automatic car
wash that uses chemical agents to wash
the vehicle.
Preferably use automatic car washes without
brushes.
If the vehicle is very dirty, pre-wash it before
cleaning it in an automatic car wash. !
Make sure that the automatic car wash is
suitable for the size of the vehicle. Fold in
the exterior mirrors before the vehicle is
washed. There is otherwise a risk of dam-
age to the exterior mirrors.
! Make sure that the automatic transmis-
sion is not in position Pwhen washing your
vehicle in a tow-through car wash.
Do not remove the key from the ignition
lock. Do not open the driver's or front-
passenger door when the engine is
switched off, as this automatically shifts
the automatic transmission to park posi-
tion Pand locks the wheels, unless you
have previously shifted the automatic
transmission to N.
! Make sure that the side windows are com-
pletely closed, that the ventilation/heater
blower is fully turned off and that the wind-
screen wiper switch is set to 0. Otherwise,
the rain sensor may be activated, triggering
unintended wiper movements. This could
cause damage to the vehicle.
After using an automatic car wash, wipe off
wax and drying agents from the windscreen
and the wiper blades. This will prevent smears
and reduce wiping noises caused by residue
on the windscreen.
High-pressure cleaners G
Risk of accident
Do not use high-pressure cleaners with circu-
lar-jet nozzles (dirt grinders) to clean your
vehicle, in particular the tyres. Otherwise, you
could damage the tyres and cause an acci-
dent.
! Observe the instructions issued by the
equipment manufacturer concerning the
distance to be maintained between the
nozzle of the high-pressure cleaner and the
vehicle (at least 30 cm).
Move the high-pressure cleaner nozzle
around when cleaning your vehicle. 168 CareOperation
