You should regularly check the pressure of theemergency spare wheel, particularly prior tolong trips, and correct the pressure as neces-sary (Ypage 307). The value on the wheel isvalid.
Snow chains must not be mounted on emer-gency spare wheels.
General notes
You can ask for information regarding permit-ted emergency spare wheels at an authorizedMercedes-Benz Center.
An emergency spare wheel may also be moun-ted against the direction of rotation. Observethe time restriction on use as well as thespeed limitation specified on the emergencyspare wheel.
Replace the tires after six years at the latest,regardless of wear. This also applies to theemergency spare wheel.
Tire pressure loss warning system (Can-ada only):as long as you are driving with theemergency spare wheel mounted, the tirepressure loss warning system cannot functionreliably. Only restart the tire pressure losswarning system when the defective wheel hasbeen replaced with a new wheel.
Vehicles with tire pressure monitor (USAonly):after an emergency spare wheel hasbeen mounted, the system may still displaythe tire pressure of the removed wheel for afew minutes. The value displayed for themounted emergency spare wheel is not thesame as the current tire pressure of the emer-gency spare wheel.

CCDD
Approachand depar-ture angleswhen thevehicle isloaded andready todrive
When the vehicle is loaded and ready to drive,it has a full tank, all fluids have been refilledand the driver is in the vehicle.
For further information about approach/depar-ture angles, see (Ypage 156).
Maximum gradient-climbing capabil-
ity
Note that the vehicle's gradient-climbing capa-bility depends on the off-road conditions andthe road surface conditions.
GLA 250: the maximum gradient climbing abil-ity is 40%.
GLA 250 4MATIC:the maximum gradientclimbing ability is 65%.
Missing values for theMercedes‑AMG GLA 45 4MATIC were notavailable at the time of going to print.
Accelerate carefully and make sure that thewheels do not spin when driving on steep ter-rain.

Technical data

If the load on the front axle is reduced whenpulling away on a steep uphill slope, the frontwheels have a tendency to spin. 4ETS recogni-zes this and brakes the wheels accordingly.The rear wheel torque is increased, making iteasier to drive off.
For further information about the maximumgradient climbing ability, see (Ypage 156).
