Driving
Economical and environmentally-friendly
driving
The amount of fue l consumption, the environ ­
mental impact and the wear to the engine,
brak es and tir es d epends mostly on your driving
style. W ith an anticipatory and economic driv ing
style, fuel consumption can be reduced by ap­ proximately 10-15% . The following tips will help
you conserve the environment and your money at the same time .
Anticip atory d riving
A vehicle uses the most fuel when acce lerating.
When you drive with ant ic ipat ion , you do not
need to brake as often and so you accelerate less .
When possible, let your ve hicle coast w ith a
g ear
e ngag ed ,
for example , when you notice that the
next traffic light is red. This produ ces a n eng ine
b raking effect, which helps to protect the brakes
and tires and reduces the emissions and fuel con­
sumption to zero (f uel shut-off during decelera ­
tion).
Shift effici ently
An effective way to save f uel is to upshift earlie r.
Staying in a gear too long uses fue l unnecessari ­
ly. Press down on the accelerator pedal slowly
and avoid "k ick-down".
Avoid full acceleration
You sho uld rare ly t ravel at the maximum vehicle
speed. High speeds cause a disp roportiona tely
h igh increase in fuel consumption, emissions and
traffic noise . Slower driving saves fuel.
Reduce idling time
The Start-Stop system * helps to reduce the id ling
time automatically . In vehicles witho ut the Start­
S top sys tem* , it is efficient to switch the eng ine
off when stopped at ra ilroad cross ings a nd long
red lights . Stopping t he engine for 30 -40 sec ­
onds already saves more fuel than the amount of
extra fuel needed to restart the eng ine .
It takes a very long time in idle to wa rm the en­
gine up to operating temperature . Wea r and
emissions are especially high in the warm -up
phase. Therefore, yo u should begin driving im-
74
mediate ly after s tarting the engine . Avoid high
RPMs whi le doing this.
Have maintenance performed regularly
By having maintenance pe rformed regu la rly on
you r vehicle, you can help to reduce fuel con ­
s u mption before you even sta rt to drive. The
maintenance condition of your vehicle not on ly
affects traffic safety and long-term value but al ­
so impacts fuel consumption. A poorly main­
ta ined engine can lead to fuel consumption that
i s 10% higher than normal.
Avo id short trip s
The engine and exha ust cleaning system must
reach their optima l operating temperature to ef­
fect ive ly reduce consumpt ion and emissions.
A cold engine uses a d isproportionately high
amount of fue l. The engine reaches operating
temperat ure and cons umption no rmalizes on ly
after approximate ly four kilometers.
Check the tire pre ssure
To save fuel, ma ke sure the tires are always in­
flated to t he corre ct pressure
¢ page 291 . The
fuel consumption can increase by 5% if the pres­
sure is only 0 .5 bar too low. Due to the increased
roll ing resistance, low tire pressures w ill also
lead to greater tire wear and will affect driving
behavior.
D rive with summer tires when possib le because
th is can increase fue l economy by up to 10%.
Eliminate unnecessary we ight
Since eve ry po und of extra weight increases f uel
consump tion, it pays to remove any unnecessa ry
weight .
A roof rac k increases the w ind resis tan ce on the
vehicle and shou ld be removed when it is not
needed . You will save approximately 12% o f you r
fuel when at speeds from 62-75 mph (100-120 km/h) .
Save energy
The eng ine d rives the genera tor , which gene rates
e lectric ity; the fuel consumpt ion also increases
with t he demand for e lec tricity . T he refore, switch ..,_

-Some noise after starting the engine is nor­
mal and is no cause for concern.
- If you leave the vehicle with the ignition
switched on, the ignition will switch off af­
ter a certain amount of time. Make sure that
electrical equipment such as the exterior
lights are switched off.
Stopping the engine
"'Bring the vehicle to a full stop.
"'Select the P or N selector lever position.
"'Press the
I START ENGINE STOPI button
r::?v page 76, fig. 90.
Steering lock
The steering locks when you turn the engine off
using the
I START ENGINE STOPI button and
open the driver's door. The locked steering helps
prevent vehicle theft.
Emergency off function
If it is absolutely necessary, the engine can also
be turned off while driving in the R, Dor S selec­
tor lever position at speeds below 6 mph (10 km/
h). To stop the engine, press and hold the
I START ENGINE STOPI button and also press the
brake pedal.
& WARNING
-Never turn off the engine before the vehicle
has come to a complete stop. The full func­
tion of the brake booster and the power
steering is not guaranteed. You must use
more force to turn or brake. Because you
cannot steer and brake as you usually
would, this could lead to accidents and seri­
ous injuries .
- Always take the key with you whenever you
leave your vehicle. Otherwise, the engine
could be started or electrical equipment
such as the power windows could be operat­
ed. This can lead to serious injury.
- For safety reasons, always park the vehicle
with the selector lever in the P position.
Driving
Otherwise, there is the risk that the vehicle
could roll unintentionally.
@ Note
If the engine has been under heavy load for
an extended period of time, heat builds up in
the engine compartment after the engine is
switched off and there is a risk of damaging
the engine. For this reason, let the engine run
at idle for approximately two minutes before
shutting it off.
(D Tips
After the engine has been switched off, the
radiator fan can continue to run for up to 10
minutes -even with the ignition switched off .
It can also switch on again after some time if
the coolant temperature rises as the result of
heat buildup or if the engine is already warm
and the engine compartment is also heated
by the sun's rays.
