carpets in the footwell, make sure the pedals
still have sufficient clearance.
During sudden driving or braking maneuvers
the objects could get caught between the
pedals. You could then no longer brake or
accelerate. This could lead to accidents and
injury.
GWarning!
With the engine not running, there is no power
assistance for the brake and steering
systems. In this case, it is important to keep
in mind that a considerably higher degree of
effort is necessary to brake and steer the
vehicle. Adapt your driving accordingly.
Starting the engine
GWarning!
Inhalation of exhaust gas is hazardous to your
health. All exhaust gas contains carbon
monoxide (CO), and inhaling it can cause
unconsciousness and possible death.
Do not run the engine in confined areas (such
as a garage) which are not properly ventilated.
If you think that exhaust gas fumes are
entering the vehicle while driving, have the
cause determined and corrected
immediately. If you must drive under these
conditions, drive only with at least one
window fully open at all times.

your safety and the safety of others, we
recommend that you pull over to a safe
location and stop before placing or taking a
telephone call. If you choose to use the
telephone while driving, please use the hands-
free device and only use the telephone when
weather, road and traffic conditions permit.
Some jurisdictions prohibit the driver from
using a mobile phone while driving a vehicle.

vehicle occupants unless the items are
securely fastened in the vehicle.
To help avoid personal injury during a collision
or sudden maneuver, exercise care when
transporting cargo. Do not pile luggage or
cargo higher than the seat backrests.
Never drive a vehicle with the tailgate open.
Deadly carbon monoxide (CO) gases may
enter vehicle interior resulting in
unconsciousness and death.
Load distribution
The Gross Vehicle Weight (GVW) which is the
weight of the vehicle includingRfuel
Rtools
Rspare wheel
Rinstalled accessories
Rpassengers
Rluggage/cargo
It must never exceed the load limit and the
Gross Vehicle Weight Rating (GVWR) for your
vehicle. The load limit and the GVWR are
specified on the placard located on the
driver’s door B-pillar (Y page 246).
In addition, the load must be distributed so
that the weight on each axle never exceeds
the Gross Axle Weight Rating (GAWR) for the
front and rear axle. The GVWR and GAWR for
your vehicle are indicated on the certification
label located on the driver’s door B-pillar
(Y page 246).
For more information, see “Tire and Loading
Information” (Y page 161).
The handling characteristics of a fully loaded
vehicle depend greatly on the load
distribution. It is therefore recommended to
load the vehicle according to the illustration
shown. The heaviest items are to be placed
towards the front of the vehicle.
i The cargo compartment is the preferred
place to carry objects. The expanded cargo
volume (Y page 128) should only be used
for items which do not fit in the cargo
compartment alone.
Please pay attention to and comply with the
following instructions when loading the
vehicle and transporting cargo:
RAlways pad off sharp edges.
RAlways place items being carried against
front or rear seat backrests, and fasten
them as securely as possible.
RThe heaviest portion of the cargo should
always be kept as low as possible against
front or rear seat backrests.
For additional safety when transporting cargo
while the rear seats are unoccupied, fasten
the outer seat belts crosswise into the
opposite side buckles :.
