cranking again, otherwise the starter
could be damaged.
4. Warm-up
Allow the engine to idle for at least 30 sec-
onds after starting. Do not race the engine
while warming it up. Drive at moderate
speed for a short distance first, especially in
cold weather. In cold weather, keep the en-
gine running for a minimum of2-3minutes before shutting it off. Starting and stopping
the engine over a short period of time may
make the vehicle more difficult to start.
5. To stop the engine, shift the shift lever to the P (Park) position or to N (Neutral) and apply
the parking brake (M/T) and push the igni-
tion switch to the OFF position.

CONTINUOUSLY VARIABLE
TRANSMISSION (CVT) (if so
equipped)
WARNING
●Do not depress the accelerator pedal
while shifting from P (Park) or N (Neu-
tral) to R (Reverse) , D (Drive) or L (Low) .
Always depress the brake pedal until
shifting is completed. Failure to do so
could cause you to lose control and
have an accident.
● Cold engine idle speed is high, so use
caution when shifting into a forward or
reverse gear before the engine has
warmed up.
● Do not downshift abruptly on slippery
roads. This may cause a loss of control.
● Never shift to either the P (Park) or R
(Reverse) position while the vehicle is
moving forward and P (Park) or D
(Drive) position while the vehicle is re-
versing. This could cause an accident or
damage the transmission.
CAUTION
● Except in an emergency, do not shift to
the N (Neutral) position while driving.
Coasting with the transmission in the N
(Neutral) position may cause serious
damage to the transmission.
● To avoid possible damage to your ve-
hicle, when stopping the vehicle on an
uphill grade, do not hold the vehicle by
depressing the accelerator pedal.
The CVT in your vehicle is electronically con-
trolled to produce maximum power and smooth
operation.

WARNING
If the shift lever cannot be moved from the
P (Park) position while the engine is run-
ning and the brake pedal is depressed, the
stop lights may not work. Malfunctioning
stop lights could cause an accident injur-
ing yourself and others.
Accelerator downshift
— in D (Drive) position —
For passing or hill climbing, depress the accel-
erator pedal to the floor. This shifts the transmis-
sion down into a lower gear, depending on the
vehicle speed.
Fail-safe
If the vehicle is driven under extreme con-
ditions, such as excessive wheel spinning
and subsequent hard braking, the fail-safe
system may be activated. The Malfunction
Indicator Light (MIL) may come on to indi-
cate the fail-safe mode is activated. For
additional information, refer to “Malfunc-
tion Indicator Light (MIL)” in the “Instru-
ment and controls” section of this manual.
This will occur even if all electrical circuits
are functioning properly. In this case, place
the ignition switch in the OFF position and
wait for 10 seconds. Then push the switchback to the ON position. The vehicle should
return to its normal operating condition. If
it does not return to its normal operating
condition, have the transmission checked
and repaired, if necessary. It is recom-
mended that you visit a NISSAN dealer for
this service.
WARNING
When the high fluid temperature protec-
tion mode or fail-safe operation occurs,
vehicle speed may be gradually reduced.
The reduced speed may be lower than
other traffic, which could increase the
chance of a collision. Be especially careful
when driving. If necessary, pull to the side
of the road at a safe place and allow the
transmission to return to normal opera-
tion, or have it repaired if necessary.
