memory can a ll be reset to zero at the same
time under
Reset in the menu.
I n addition, you can determine what informa­
tion from the trip computer should be shown
in the instrument cluster d isplay. If one of the
p ieces of driver information is turned
Off, that
driver information will not be shown in the
display. The information will continue to be
calculated by the trip computer and can be
turned back
On at any time .
@ Tips
-This function is not available on all
vehicles.
- The dr iving information in the efficiency
program is also reset to zero with the
s ingle-trip memory.
Gearshift Indicator
App lies to vehicles: with manua l transmission and gear­
shift indicator
This indicator can help conserve fuel.
F ig. 12 Disp lay : Gea rs hift indicator
In order to become familiar with the gearshift
indictor, at first just drive the way you are
used to. If the current gear -and the driving
situa tion -is not the best one for conserving
fuel, then the indicator will display the recom­
mended gear. The display shows the current
gear and the gear that is recommended
¢ fig. 12.
- Upshifting The display will light up to the
right of the gear currently se lected if it is
recommending a higher gear.
-Downshifting: The display will light up to
the
left of the gear currently selected if it is
recommend ing a lower gear.
Sometimes the indicator will recommend
skipping a gear (3
> S).
If there is no gearshift recommendation, then
j us t drive in the appropriate gear for conserv­
ing fuel.
(D Note
This indicator can help you conserve fuel.
This indicator is not meant to show you
which gear you should always be in in all
driving situations . Sometimes, in situa­
tions such as passing, driving through
mountains or when towing a trailer, there
won't be any gearshift recommendation.
@ Tips
The display does not light up when the
clutch pedal is being depressed.

damage to the load and even the vehicle
itse lf.
- Make sure that the open rear lid and the
sunroof do not come into contact with
objects on the roof.
Loading the roof rack
Always distribute loads evenly. J\llake sure
anything on the roof rock is securely tied
down.
.. Always dist ribute the loads on the roof rack
evenly .
.. Always attach items to the roof rack securely
before you drive off.
The maximum permissible roof weight is
2 00 lb (90 kg ). The roof weight is the total of
the we ight of the roof rack, the attachments
and the cargo you are carry ing. You must also
not exceed the maximum load weight for the
roof rack you are using .
When us ing a roof rack system which has a
lower load carry ing capac ity , you must not use
up the total max imum perm issible load carry­
ing capacity specified above. Instead, you
should load the roof rack system only to the maximum capacity spec ified by the manufac­
turer of the roof rack system.
A WARNING
Weak, damaged or improper straps used
to secure items to the roof rack can fail
during hard braking or in a co llision and
cause serious personal injury.
- Make sure the roo f rack is insta lled exact­
ly as specified above
,=;,page 69.
- Always use suitable mounting straps for
sec uring items to the roof rack to help
prevent items from shifting or flying for­
ward.
- Items on the roof rack must always be
sec urely mo unted.
- T he use of a roof rack can negative ly af ­
fect the way a vehicle handles . Cargo
that is large, heavy, bulky, long or flat
will have a greater negative influence on
.
the vehicle's aerodynamics, center of
grav ity and overall handling. Always
drive s lowly, avoid sudden braking and
maneuvers when transporting cargo on
the roof of your vehicle.
- Never exceed the maximum permissible
load carrying capacity of the roof of your
veh icle, the permissible axle weights and
the permissible total weight of you r vehi­
cle~
page 280, Weights.
(D Note
Make sure that the opened rear lid does
not come in contact with the cargo on the
r oof.
@ For the sake of the environment
As a result of the increased wind resist­
ance created by a roof rack, you r vehicle is
us ing fuel unnecessarily . So remove the
r oof rack after using it.

General information
A WARNING
Read and follow t he important safety pre­
cautions o n
~ page 132, S towing lug­
gage.

7 4 Seats and storage
If nothing is hung on the hooks, they will fold
back in by themselves.
In a collision, the laws of physics mean that
even smaller items that are loose in the vehi­
cle will turn into heavy missiles that can cause
serious injury. Items in the vehicle p ick up ki­
netic energy which varies with the vehicle and
the weight of the item . Vehicle speed is the
most significant factor .
For example, in a frontal collision at a speed
of 30 mph (48 km/h), the forces acting on a 10-lb (5 kg) object a re about
20 times the
normal weight of the item. This means that
the weight of the item would suddenly be the
equ ivalent of about 200 lbs (90 kg). One can
easily imagine the injuries that an item of that
weight flying freely through the passenger
compartment can cause in a collision at a
speed considered relatively low .
8_ WARNING
Weak, damaged or improper straps used
to secure items to tie-downs can fail dur­ ing hard braking or in a collision and cause
serious personal injury.
- Always use suitable retaining straps and
properly secure items to the tie-downs in
the luggage compartment to help pre­
vent items from shifting or flying for­
ward .
- Never attach a child seat tether strap to
a tie -down.
- For strength-related reasons, the mount­
ing hooks can only be used to secure ob­
jects weighing up to 10 lb. (5 kg) . Heavi ­
er objects will not be adequately secured
- there is a r isk of injury.
Tie-downs
Applies to vehicles: with tie-downs
Four tie-downs for securing luggage pieces
and two for hanging bags , sacks, etc. are
lo­
cated in the luggage compartment.

A WARNING
-The ski sack is intended only for the
transportation of skis and other light ob ­
jects . To reduce the risk of serious per­
sonal injury, never transport heavy or
pointed objects in the ski sack.
- When braking rapidly or during an acci­
dent, the load could be displaced and
cause injury to occupants.
- Sharp edges on the load must be covered
for protection. Always fasten the belt
tightly around the sack and its contents
