on the time of year, people inside the ve
hicle can be exposed to very high or very
low temperatures .
0 Note
Avoid high engine rpm, full throttle and
heavy engine loads until the engine has
reached operating temperature -other-
wise you risk engine damage.
@ For the sake of the environment
Do not let the engine run while parked to
warm up . Begin driving immediately. This
reduces unnecessary emissions.
@ Tips
- After starting a cold engine, there may
be a brief period of increased noise be
cause the oil pressure must first build up in the hydraulic valve adjusters . This is
normal and not a cause for concern .
- If you leave the vehicle with the ignition
switched on, the ignition will switch off
after a certain period of time . Please
note that electrical equipment such as
exterior lights will switch off as well
when that happens .
Switching engine off
App lies to vehicles: with Conve nie nce key

Steering lock
The steering locks when you turn the engine
off using the
I S TAR T ENGINE STOP I button
and open the d river 's doo r. T he locked steer

Emergency off
If necessary, the engine can be switched off
with the selector lever in the R or D/S posi
tions. To do so , step on the brake pedal and
press and hold the
I START ENGINE STOP I but-

ton. The vehicle speed must be less than 6
mph/ 10 km/h.
A WARNING
- Never turn off the engine before the ve
hicle has come to a complete stop . The
full function of the brake booster and the power steering is not guaranteed . You
must use more force to turn or brake if
necessary . Because you cannot steer and
brake as you usually would, this could
lead to crashes and serious injuries.
- For safety reasons, you should always
park your vehicle with the selector lever
in P . Otherwise, the vehicle could inad
vertently roll away.
- The radiator fan can continue to run for
up to 10 minutes even after you have
turned off the engine and removed the ignition key. The radiator fan can also
turn on again if the engine coolant heats
up because of intense sunlight or heat
build-up in the engine compartment.
- 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 operated. This can lead to seri
ous inJury.
- Never leave children or persons requiring
assistance unattended in the vehicle. The
doors can be locked using the remote
transmitter, preventing people from es
caping from the vehicle on their own in
the event of an emergency. Depending
on the time of year, people inside the ve hicle can be exposed to very high or very
low temperatures.
(D Note
If the engine has been under heavy load
for an extended period, heat builds up in
the engine compartment after the engine is switched off -there is a risk of damaging
the engine. Allow the engine to run at idle
for about two minutes before switching it
off .

your vehicle and other vehicles.
- For reasons of safety, cruise control
should not be used in the city, in stop
and-go traffic, on twisting roads and
when road conditions are poor (such as
ice, fog, gravel, heavy rain and hydro
plan ing) -you could have an accident.
- Switch the cruise control off temporarily
when dr iv ing in turning lanes, highway
exits or in construction zones.
- Please note that unconsciously "resting"
your foot on the accelerator pedal causes
cru ise contro l not to brake. This is due to
the control system being overridden by
the driver's acceleration.
- Never use the cruise control when driving
off-road or on unpaved roads. The cruise

vehicle is being operated on paved roads,
and is not suitable for use off-road or on
unpaved roads.
- If a brake system malfunction such as
