At a glance

The headlamp range control is used to adapt the
downward angle of the headlamp beams in
accordance with the load on your vehicle. The
cone of light from the headlamps changes if
seats are occupied or if the cargo compartmentis being loaded or unloaded. This can impair vis-
ibility and cause glare to oncoming traffic.
You can only adjust the headlamp range while
the engine is running.
XTurn headlamp range control :to the cor-
responding position. The road ahead should
be lit up for 40 mto 100 mand the low-beam
headlamps should not cause glare to oncom-
ing traffic.
Select position gif the vehicle is unladen.
Cornering lamps
The cornering lamps improve the illumination of
the road over a wide angle in the direction you
are turning, enabling better visibility in tight
bends, for example.
The cornering light function switches on
automatically, if:
Ryou are traveling at a speed of less than
25 mph (40 km/h) and you switch on a turn
signal or turn the steering wheel.
Ryou are traveling at a speeds of between
25 mph (40 km/h) and 43 mph (70 km/h) and
turn the steering wheel.
The cornering lamp may remain lit for a short
time, but is automatically switched off after no
more than 3 minutes.
iIf reverse gear is engaged the lamp on the
opposite side of the vehicle switches on
instead.
Hazard warning lamps
GWARNING
The rear exterior light will be covered if you:
Ropen the rear doors by 90°
Ropen the rear dropside.
The vehicle will then be difficult for other road users to see or will not be seen by them at all,
particularly if it is dark or visibility is poor.
There is a risk of an accident.
You should therefore ensure in this and simi-
lar situations that the vehicle is visible from
the rear in accordance with the relevant
national regulations, by using the warning tri-
angle, for instance.
Hazard warning lamp switch
XTo switch on/off: press the£hazard
warning lamp switch.
If you have indicated a turn while the hazard
warning lamps are switched on, only the turn
signal lamps on the side of the vehicle selected
will light up.
The hazard warning lamps switch on automati-
cally if:
Ran air bag is deployed.
Ryou brake sharply and bring the vehicle to a
halt from a speed of more than 45 mph
(70 km/h).
If the hazard warning lamps have been switched
on automatically, press the £hazard warn-
ing lamp switch to switch them off.
iThe hazard warning lamps work even when
the ignition is switched off.
Headlamp cleaning system
The headlamps are cleaned automatically with a
high-pressure water jet if the "Wipe with washer
fluid" function is activated (
Ypage 96) while
the low-beam headlamps are on and the engine is running.
You can find information on refilling washer fluid
in the "Maintenance and care" section
(
Ypage 225).

Windshield wipers
Switching the windshield wiper
on/off
!
Do not operate the windshield wipers when
the windshield is dry, as this could damage
the wiper blades. Moreover, dust that has col-
lected on the windshield can scratch the glass
if wiping takes place when the windshield is
dry. If it is necessary to switch on the windshield
wipers in dry weather conditions, always use
washer fluid when operating the windshield
wipers.
!If the windshield wipers leave smears on the
windshield after the vehicle has been washed
in an automatic car wash, wax or other resi-
dues may be the reason for this. Clean the
windshield using washer fluid after washing
the vehicle in an automatic car wash.
!Vehicles with rain/light sensor:
Switch the wipers off in dry weather. Other-
wise, dirt or optical effects may cause unde-
sired windshield wiper sweeps. This could
then damage the windshield wiper blades or
scratch the windshield.
The windshield will no longer be wiped properly
if the wiper blades are worn. Replace the wiper
blades twice a year (
Ypage 97), ideally in
spring and fall.

XTo wipe with washer fluid: press the com-
bination switch beyond the pressure point in
the direction of arrow :.
The detent positions of the combination switch

Lights and windshield wiper s

iCanada only:
If the wind shield wiper s areswitched on and
you stop the veh icle, the windshield wiper
speed isreduced. For example, ifyou have
selected level IIand stop the veh icle,wipin g
continues with intermittent wipe whilethe
veh icle is stationary. Ifintermittent wipe is
selected, the intervals become longer.
Vehicles with a rain and light sensor: you
can use level Ias the universal setting. The
rain and light sensor sets the appropriate wip-
ing frequency automatically, according to the
intensity of the rain. When you stop the veh i-
cle, leve lsIII and IIare swit ched down to
level Iautomatically.
The wind shield wiper will return to the original
level when you drive faster than 5 mph
(8 km/h).
You can adjust the sensitivit y of the rain and
light sensor using the on-board computer
(
Ypage 171).
In formation on checking the washer fluid level
can befound inthe "Maintenance and care"
section (
Ypage 225).

Replacing the wiper blades
GWARNING
If the wind shield wipers begin to move while
you are changing the wiperblades, you could
be trapped by the wiper arm. There isa risk of
injury.
Always switch off the windshield wipers and
ignition before changing the wiper blades.
!Never open the hood if a windshield wiper
arm has been folded away from the wind-
shield.
Never fold a windshield wiper armwithout a
wiper blade back onto the windshield/rear
wind ow.
Hold the windshield wiper arm firmly when
you change the wiper blade. If you release the
windshield wiper arm without a wiperblade
and itfalls onto the windshield, the windshield
may be damaged by the force of the impact.
We recommend that you have the wiper
blades replaced at a qualified specialist work-
shop.
!Only hold the wiperblade by the wiperarm.
You could otherwise damage the wiper rub-
ber.
The wind shield will no longerbe wipedproperly
if the wiper blades are worn. Replace the wiper
blades twice a year, ideally in spring and fall.
