[ i J Tips
If the climate control system is operating in cooling mode, air flows
primarily from the outlets in the center console and in the door
pillars . To achieve adequate cooling, you should never close the
outlets completely. •
Using climate controls economically
Using the climate controls prudently can help save fuel.
When you use the air conditioner, engine power is reduced
and fuel consumption increases. To save fuel, you should
use the air conditione r only when necessary. Also please
n ote the following points:
- If you want to save fuel, activate ECON.
If you are going to drive with the windows open, use
ECON.
W For the sake of the environment
By reducing the amount of fuel you use, you also reduce the amount
of pollutants emitted into the air.•

& WARNING
Improperly stored luggage or other items can fly through the
vehicle causing serious personal injury in the event of hard braking or an accident. To help reduce the risk of serious personal injury:
• Always put objects, for example, luggage or other heavy items
in the luggage compartment.
• Always secure objects in the luggage compartment using the
tie-down hooks and suitable straps.
& WARNING
Heavy loads will influence the way your vehicle handles. To help
reduce the risk of a loss of control leading to serious personal
injury :
• Always keep in mind when transporting heavy objects, that a
change in the center of gravity can also cause changes in vehicle
handling:
-Always distribute the load as evenly as possible.
- Place heavy objects as far forward in the luggage compart-
ment as possible.
• Never exceed the Gross Axle Weight Rating or the Gross
Vehicle Weight Rating specified on the safety compliance sticker on the left door jamb. Exceeding permissible weight standards
can cause the vehicle to slide and handle differently.
• Please observe information on safe driving
~ page 200.
& WARNING
To help prevent poisonous exhaust gas from being drawn into the
vehicle, always keep the rear lid closed while driving.
• Never transport objects larger than those fitting completely
into the luggage area because the rear lid cannot be fully closed.
& WARNING (continued)
• If you absolutely must drive with the rear lid open, observe the
following notes to reduce the risk of poisoning :
- Close all windows,
- Close the power roof,
- Open all air outlets in the instrument panel,
- Switch off the air recirculation,
- Set the fresh air fan to the highest speed.
& WARNING
Always make sure that the doors, all windows , the power roof and
the rear lid are securely closed and locked to reduce the risk of
injury when the vehicle is not being used.
• After closing the rear lid, always make sure that it is properly
closed and locked .
• Never leave your vehicle unattended especially with the rear lid
left open. A child could crawl into the vehicle through the luggage
compartment and close the rear lid becoming trapped and unable
to get out . Being trapped in a vehicle can lead to serious personal
injury.
• Never let children play in or around the vehicle.
• Never let passengers ride in the luggage compartment. Vehicle
occupants must always be properly restrained in one of the
vehicle's seating positions.
[ i] Tips
Air circulation helps to reduce window fogging. Stale air escapes to
the outside through vents in the trim panel, on the left side of the
luggage compartment. Be sure to keep these slots free and open. •
