2023 INFINITI QX50 snow chains

•If brake related parts such as brake pads,
rotors and calipers are not INFINITI rec-
ommended or are extremely deterio-
rated, the VDC system may not operate
properly and both the
and theindicator lights may illuminate.
• If engine control related parts are not
INFINITI recommended or are extremely
deteriorated, both the
andindicator lights may illuminate.
• When driving on extremely inclined sur-
faces such as higher banked corners, the
VDC system may not operate properly
and the
indicator light may flash or
both theandindicator lights
may illuminate. Do not drive on these
types of roads.
• When driving on an unstable surface
such as a turntable, ferry, elevator or
ramp, the
indicator light may flash
or both theandindicator
lights may illuminate. This is not a mal-
function. Restart the engine after driv-
ing onto a stable surface. •
If wheels or tires other than the INFINITI
recommended ones are used, the VDC
system may not operate properly and
the
indicator light may flash or both
theandindicator lights may
illuminate.
• The VDC system is not a substitute for
winter tires or tire chains on a snow cov-
ered road. The chassis control is an electric control mod-
ule that includes the following functions:
• Active Trace Control
• Active Engine Brake
• Active Ride Control
ACTIVE TRACE CONTROL
This Active Trace Control senses driving
based on the driver’s steering and
acceleration/braking patterns, and controls
brake pressure at individual wheels to aid
tracing at corners and help smooth vehicle
response.
When the lower display is used to turn off the
Vehicle Dynamic Control system, the Active
Trace Control system is also turned off.
When the PERSONAL mode is selected, the
Active Trace Control can be set to ON (en-
abled) or OFF (disabled).

5-144Starting and driving

Check for and remove objects obstructing
the area around the sonar sensors.
Do not attach stickers (including transparent
material), install accessories or apply addi-
tional paint near the sonar sensors.
Do not strike or damage the area around the
sonar sensors. It is recommended that you
visit an INFINITI retailer if the area around
the sonar sensors is damaged due to a
collision.FREEING A FROZEN DOOR LOCK
To prevent a door lock from freezing, apply
de-icer through the key hole. If the lock be-
comes frozen, heat the key before inserting it
into the key hole, or use the INFINITI Intelli-
gent Key.
ANTIFREEZE
In the winter when it is anticipated that the
temperature will drop below 32°F (0°C),
check the antifreeze to assure proper winter
protection. For additional information, see
“Engine cooling system” (P. 8-4).
BATTERY
If the battery is not fully charged during ex-
tremely cold weather conditions, the battery
fluid may freeze and damage the battery. To
maintain maximum efficiency, the battery
should be checked regularly. For additional
information, see “Battery” (P. 8-12).
DRAINING OF COOLANT WATER
If the vehicle is to be left outside without
antifreeze, drain the cooling system, including
the engine block. Refill before operating the
vehicle. For additional information, see
“Changing engine coolant” (P. 8-5).
TIRE EQUIPMENT
1. SUMMER tires have a tread designed toprovide superior performance on dry
pavement. However, the performance of
these tires will be substantially reduced in
snowy and icy conditions. If you operate
your vehicle on snowy or icy roads,
INFINITI recommends the use of MUD &
SNOW or ALL SEASON TIRES on all four
wheels. It is recommended that you visit
an INFINITI retailer for the tire type, size,
speed rating and availability information.
2. For additional traction on icy roads, stud- ded tires may be used. However, some
U.S. states and Canadian provinces pro-
hibit their use. Check local, state and pro-
vincial laws before installing studded tires.
Skid and traction capabilities of studded
snow tires on wet or dry surfaces may be
poorer than that of non-studded snow tires.
3. Tire chains may be used. For additional information, see “Tire chains”(P. 8-38).

VEHICLE RECOVERY (freeing a
stuck vehicle)
WARNING
To avoid vehicle damage, serious personal
injury or death when recovering a stuck
vehicle:
• Contact a professional towing service to
recover the vehicle if you have any ques-
tions regarding the recovery procedure.
• Tow chains or cables must be attached
only to main structural members of the
vehicle.
• Do not use the vehicle tie-downs to tow
or free a stuck vehicle.
• Only use devices specifically designed for
vehicle recovery and follow the manu-
facturer's instructions.
• Always pull the recovery device straight
out from the front of the vehicle. Never
pull at an angle.
• Route recovery devices so they do not
touch any part of the vehicle except the
attachment point. If your vehicle is stuck in sand, snow, mud,
etc., use a tow strap or other device designed
specifically for vehicle recovery. Always fol-
low the manufacturer's instructions for the
recovery device.
Rocking a stuck vehicle
WARNING
• Stand clear of a stuck vehicle.
• Do not spin your tires at high speed. This
could cause them to explode and result in
serious injury. Parts of your vehicle could
also overheat and be damaged.
If your vehicle is stuck in sand, snow, mud,
etc., use the following procedure:
1. Turn off the Vehicle Dynamic Control (VDC) system.
2. Make sure the area in front and behind the vehicle is clear of obstructions.
3. Turn the steering wheel right and left to clear an area around the front tires. 4. Slowly rock the vehicle forward and
backward.
• Shift back and forth between R (Re- verse) and D (Drive).
• Apply the accelerator as little as pos- sible to maintain the rocking motion.
• Release the accelerator pedal before shifting between R (Reverse) and D
(Drive).
• Do not spin the tires above 35 mph (55 km/h).
5. If the vehicle cannot be freed after a few tries, contact a professional towing ser-
vice to remove the vehicle.
